KOMERI Research Centre Selects Unisim Software
The Unisim software from Honeywell will provide a series of unified simulation solutions to improve performance throughout the lifecycle of the centre, allowing KOMERI to create the virtual environments necessary to support LNG-FPSO training and education services required by Korea's shipbuilding and offshore companies. Tae-Hyoung Kim, head of the KOMERI testing and certification centre, said: 'KOMERI needs to build these virtual environments to help our country's top shipbuilders and leading companies in heavy industries strengthen their positions for LNG-FPSO projects around the world.
'By using Multi-Purpose Dynamic Simulator (MPDS) technologies, which is based on Honeywell's equipment, software and services, these companies will be able to make use of technologies, which will help them develop better plant designs, and which will in turn improve their operations,' Kim added. Whether for simulation of on-line or off-line process unit design and optimisation applications, Honeywell said Unisim has the capabilities to help customers realise benefits across the lifecycle of their facilities. Shipbuilding and offshore companies can capture and share process knowledge, improve profitability and maximise the return on their simulation investments.
Water Plant Cuts Costs with Net Concentrator
Automation systems at the facility control processes that ensure the quality of the treated water and compliance with state health department and EPA regulations. To update its operations and increase efficiency, the OCWA decided to switch from analogue remote terminal units to digital control systems through an online Scada system powered by Ethernet and Modbus network communications. Moore Industries helped the OCWA in implementing its new system by delivering isolated I/O modules, which eliminate potential signal loop interference from the Ethernet control network.
The I/O modules within the Net Concentrator system contain ground loops or other individual aberrations locally, stopping them from impacting other readings at the site. The system also reduced total wiring by transmitting process control and monitoring signals across a single digital communications link. Geoffrey G Miller, executive engineer at the OCWA, said: 'Having isolated I/O modules was critical to the success of our facility control process upgrades. 'This system allows our technicians to view I/O directly from the plant through a local HMI or laptop.
'Doing this has saved us time and money by reducing trips to the field,' he added. Installing the Net Concentrator system helped the OCWA solve several data collection problems, according to Moore Industries. The ability to monitor the water filtration beds in real time has improved operator reaction time and increased efficiency. In addition, it is said to be a reliable solution in reducing overhead related to hard wiring and maintenance.
Venting Function for Safety Relief Valves
Witt-Gasetechnik has developed a venting function for safety relief valves, enhancing accident prevention and advantageous when handling flammable and toxic gases. The SV805 A enables functional tests of installed Witt safety relief valves at any time. Andreas Heyer, product manager at Witt-Gasetechnik, said: 'The Witt relief valve SV805 A with straight design has been developed especially for venting with a connected blow-off pipe.
'The escaping gas is not emitted into the ambient air but rather directly led into the blow-off pipe by using the venting function,' he added. In practice, the function enables time savings as safety relief valves previously had to be dismounted for functional tests, which could result in a substantial installation effort. Safety relief valves protect vessels and pipes in gas-technical plants from critical overpressure. The valves blow off gas automatically when the preset opening pressure is reached.

Seal-less Motors Withstand Contact with Salt Water
Astrosyn has announced that its latest range of hybrid seal-less stepper motors can operate in wet and corrosive environments thanks to advanced anti-corrosion coatings. A range of corrosion-proof coatings applied to every surface and component, both inside and outside, enables the motors to withstand prolonged contact even with salty water. Traditionally, motors intended for harsh environments are fitted with seals on their shafts and end caps.
However, temperature variations in particular mean than sooner or later these allow in moisture and contaminants, which eventually lead to corrosion and failure. Stepper motors are particularly susceptible to the effects of corrosion, owing to the small air gaps between their rotors and stators. The coatings and materials used in the Astrosyn motors are tailored to each component.
For example, the permanent magnets, aluminium endbells and steel laminations are made from upgraded materials before being given an appropriate coating. Another advantage of eliminating seals, according to Astrosyn, is that seals around the shaft introduce additional friction, which causes a significant reduction in torque. Suitable applications for the motors include mobile phone masts, marine antennas, food processing equipment, chemical industries, and the automotive sector.

Brewery Selects Chronos BTH in-Process Weigher
Chronos BTH has worked with family brewery Joseph Holt to update its malt intake weighing system, replacing an old mechanical scale with an Atex-compliant Chrono-Bulk APW in-process weigher. With access to the malt weighing room being severely restricted, the Chronos BTH engineers designed new infeed and discharge chutes that could be manoeuvred into the existing space. Similar restrictions applied to the APW weigher, which was originally conceived for restricted-space applications such as this.
The old mechanical scale was dismantled in situ and the individual parts were moved out of the malt weighing room. Following the reconfiguration of the infeed and discharge chute work, the APW weigher was moved into position and installed. The Chronos-Weigh PC456 weighing controller was mounted remotely from the weigher on the wall of the malt weighing room, enabling compliance with the required Atex zoning requirements.

RVA Supplies Decommissioning Services to Ineos
RVA Group has been appointed by PVC manufacturer Ineos Chlorvinyls to manage large-scale UK decommissioning projects in Barry and Runcorn. Ineos Chlorvinyls engaged RVA to oversee the safe execution of the two major projects and ensure the maximisation of income from the resale of redundant plant and metallic arisings including high-value exotic alloys. RVA commenced its role at Ineos Chlorvinyls' Barry site after manufacturing ceased in March 2010 as part of a consolidation of activities.
Having planned to decommission and clean the site before handing it back to the landlord with the plant intact, Ineos sought RVA's isolation and decommissioning guidance. However, acknowledging the financial implications of Ineos's proposed site exit strategy, RVA conducted a series of in-depth feasibility and option studies to investigate more commercially attractive routes for the client. Utilising its knowledge and experience of asset recovery, RVA recommended that Ineos hand the site back as flat slab, as plant demolition and dismantling could generate an income from the sale of the process equipment; some had potential for re-use, while other items (as a result of their high-value metallurgy) would create a positive income stream.
To demonstrate its confidence in the proposed alternative site exit strategy, RVA agreed to work for six weeks - at risk - to test the feasibility of its solution. If the project plan had proven unachievable, RVA would have waived all costs for work undertaken during this investigatory period. However, RVA's team was able to demonstrate that the project could be delivered with significant cost savings, reducing the financial burden for Ineos. RVA is now project managing the dismantling and demolition of Ineos Chlorvinyls' production facilities, including process vessels, aluminium and concrete storage silos, a boilerhouse and three steel 1,500m3 storage spheres.
With a 27-man team on site, and kit ranging from excavators with shears and grab buckets to an ultra-long-reach machine, safety remains the main priority. Colin Hopwood, site services manager - Runcorn at Ineos Chlorvinyls, said: 'RVA's role with Ineos commenced with the team's development of a detailed redundant asset management review for our Runcorn site. 'The company drew on its technical engineering experience to assess a number of plants, projected costs of removal, optimised sequencing and a potential rolling decommissioning programme for several areas of the 125-hectare top-tier COMAH site.
'The quality and integrity of this guidance led us to proceed with the Runcorn works and I also recommended RVA's services to a colleague heading up the Barry project,' Hopwood added. Since the sequential decommissioning and demolition of five redundant chemical processing plants began on the high-hazard Runcorn site in August 2010, the site has remained operational elsewhere. Meticulous planning and project co-ordination has therefore been essential to ensure minimal disruption and utmost safety for all parties.
Priority was given to the complex dismantling of Ineos's four distillation columns, ranging from 40-60m in height, which had to be dismantled to a low height before the arrival of the year's high winds. However, due to their proximity to high-hazard pipelines, and given the inherently dangerous nature of hot-cutting techniques, an alternative dismantling process had to be devised. Instead, RVA oversaw the more time-intensive, but safer alternative of using high-pressure abrasive waterjets that ran around the circumference of the columns' cut lines to eliminate the flammable risks, before the top sections could be removed with a lifting nail attached to a 500t crane.
With six months of the programme still to complete, RVA is planning for the dismantling of Ineos's anhydrous caustic soda plant - a procedure that will take place in May 2011. Although the asset is no longer needed by Ineos, the plant is in good condition and is being dismantled for re-erection elsewhere. Due for completion in August 2011, the clearance of the redundant assets within Ineos's Per-Tri, Per-Tri Shipping, ACS, VDC4 and KOH plants will prepare the site for potential new Ineos ventures.

Combustibles Sensor Upgrade Kit for Analyser
Gas analysis specialist Servomex has launched a combustibles sensor upgrade kit for the Servotouch Fluegas (2700) combustion gas analyser. The sulphur-resistant combustible sensor upgrade kit enables a Tfx sensor operating at standard temperature to operate at an elevated temperature, improving performance in high sulphur applications, where excess levels of SO2 can inhibit traditional catalytic sensor function.
In addition to improved performance, Servomex said the sensor upgrade will increase longevity and reduce service downtime where SO2 levels generally exceed 1,000ppm. For applications where the existing combustibles sensor has less than 13 months operational life left, the upgrade is anticipated to extend sensor life. The ability for the combustibles sensor to operate at higher temperatures makes it suitable for a number of applications where coal or heavy oil is the fuel, making it applicable in industries such as power generation.
The Fluegas's high-sensitivity sensor specification remains appropriate for applications where high levels of sulphur are not present, including applications such as natural gas and light oils. The sulphur-resistant combustibles sensor is suitable for all models of the Fluegas (2700A1, 2700A2, 2700B1, 2700C1). The upgrade kit is available for general-purpose versions of the sensor head, with a kit for Div 2 and Zone 2 analysers to follow during 2011.

XY Stage for Inverse Microscope Applications
The stage is driven by a Piline piezoceramic linear motor, which, in contrast to flanged stepper or DC motors with large leadscrew ducts, is integrated inside the stage and therefore does not require any additional installation space. This facilitates the integration of the stage under the microscope and offers unhindered access to the specimen. The Piline motors transmit the force directly to the moving platform, thus keeping the position stable, even when powered down. As a result, they do not generate additional heat. M-687 stages provide maximum closed-loop velocities of up to 250mm/sec. Their settling behaviour is optimised; settling takes place within a few milliseconds.
A slow movement is also important for users; even if a distance of only a few micrometres per second is covered, the movement can still be observed under the microscope at 1,000-fold magnification. By combining a Piline drive with a high-resolution position sensor, a stiff and high-precision stage has been designed that can reach positions repeatedly with submicron accuracy. This is said to be useful for imaging methods such as tiling and stitching that are required for large specimens.
PIR Motion Detectors Support Energy-Saving Schemes
Providing a 10A-rated normally open volt-free output, the detectors will switch loads at any voltage and are not restricted to 230VAC mains tasks. According to the company, 24VAC/VDC supply versions are also available for applications without a mains supply or where safe, low-voltage operation is required. With a 110deg sensing angle and a reach of 2.8m, the 18.21-0300 and 18.31-0300 PIRs will handle all types of regular ceiling-height applications. For high-bay or extended-ceiling-height duties, the 18.31-0031 PIR variant offers a longer sensing range of up to 8m.
The Finder PIRs also offer an adjustable light threshold setting, enabling operation to be varied according to ambient light conditions. In addition, an enhanced light-on time adjustment of up to 35 minutes makes the PIRs suitable for HID lamp applications, which, for reasons of preserving lamp life, place a restriction on the number of starts per hour.
SKF Provides Compressed-Air Management Service
SKF has developed an energy management and monitoring service designed to identify opportunities for the system optimisation and energy reduction of compressed-air systems. The service, called SKF Energy Monitoring Services - Compressed Air Systems, consists of a plant evaluation to identify the key compressed-air system assets and specific areas of end use. Plant data is then collected and analysed to measure and monitor compressed-air system performance and reports provided by SKF specialists highlight the key opportunities for system optimisation and savings.
'We are able to customise this service to each facility's needs and recommend corrective actions to improve system efficiency and reduce costs that are appropriate to the needs of each facility,' said Mike Dwyer, an energy and sustainability management specialist. Without a leak detection and repair programme in place, up to 30 per cent of a system's capacity can be lost to leaks, according to the US Department of Energy.
SKF Energy Monitoring Services - Compressed Air Systems solves this problem, using proven methodologies to detect compressed-air leaks, calculate system losses and provide a method to monitor, optimise and maintain system efficiency, said the company. In addition, the service integrates the SKF Marlin, SKF Aptitude Analyst and SKF Aptitude Inspector measurement and maintenance technologies.

Temperature Data Logger for Use in Meat Industry
The RFOT never needs to be connected to a computer as it has been designed for two-way wireless communication. Full communication can be performed directly from a central PC. In addition to wirelessly transmitting data, the RFOT stores each reading to internal memory for backup. This backup data may be retrieved wirelessly at a later time. The company's easy-to-use software features user-programmable critical control points, called 'cooling flags', to ensure compliance with USDA Appendix B. The cooling flags are automatically annotated on the graph and tabular data views.
The summary tab provides the cool-down duration between each critical control point. The data can also be automatically exported to Microsoft Excel for further calculations. Madgetech offers free firmware upgrades for the life of the product so that data loggers already deployed in the field can grow with new technological developments. Units do not need to be returned to the factory for upgrades; the user can do this automatically from any PC.
Vistagy to Present Fibresim Composites Software
Vistagy will emphasise the growing role of composites in the automotive market at the JEC Composites Show on 29-31 March in Paris, France. The company, which will be exhibiting on Stand T45, claims that its Fibersim composites engineering software supports the entire design-to-manufacturing process for highly engineered products. There are many challenges in adopting structural composites for the high-volume automotive market, including the need to provide engineers with rapid and accurate structural and crash performance analysis; new design methods suitable for high-rate composite manufacturing; and tools for selecting and simulating new materials and processes as well as cost and weight feedback early in the design process.
Fibersim is said to solve these challenges with a variety of capabilities, including multi-layer material simulation - a significant factor in automotive composites that provides insight into the drape-ability of non-crimp fabrics (NCFs) and other new materials - as well as the corresponding manufacturing processes such as forming. The engineering software promotes an open and flexible approach to supporting the entire design-to-manufacturing process. The Vistagy stand will feature the new Lotus Renault GP (LRGP) racing car, which was designed using Fibersim.
Ian Goddard, LRGP's senior CAE engineer who leads the composites design efforts for the company, will also be found on the stand. There will also be demonstrations of Fibersim 2010. On 30 March in the Composites Simulation Forum, David Leigh Hudson, Vistagy's director of product and market strategy for Fibersim, will deliver a presentation entitled 'Simulations for Materials and Manufacturing Processes in Composite Intensive Industries'. Attendees will learn how material- and manufacturing-specific simulations can assist with assessing material deformation and degradation and how specific simulation types can enhance product development.

Wire-to-Wire Feedthroughs Solve Signal-Loss Issues
Wire-to-wire feedthroughs from Douglas Electrical are designed for applications such as thermocouple sensors where signal loss can become an issue. Providing power and/or signal transmission into and out of vacuum or pressure environment is simplified with the fully harnessed wire-to-wire feedthroughs. A continuous wire feedthrough without the need for connectors can solve many signal-loss challenges, according to the company.
For applications requiring shielded conductors, the ability to carry the shielding uninterrupted through the feedthrough preserves attenuation. Design engineers can specify the type and mix of conductors and feedthroughs, as well as custom terminal requirements, as needed. Douglas wire-to-wire feedthroughs can withstand pressure up to 15,000psi and temperatures ranging from cryogenic to more than 350F.

Lifting and Handling Unit for Sterile Environments
Base Handling Products has developed a 'controlled environment' lifting and handling system for aseptic pharmaceutical applications and industries including foodstuffs, microelectronics and research. The system is suitable for use in any stage of a production process where there may be risk of physical or airborne contamination. It can replace other mechanical systems or be used in place of purely manual handling.
By providing a controlled environment the unit enables previously hermetically sealed bags, containers or components to be opened/or handled and discharged without risk of contamination. The first unit was developed for a multi-national pharmaceutical manufacturer to remove the potential contamination of double-wrapped irradiated/autoclaved bags of rubber bungs prior to loading into a filling machine. This was achieved by the design and installation of a glove ported enclosed hoist that removed the operator intervention as much as possible from the loading operation.
The handling system suitable for a grade A pharmaceutical environment had to provide a physical envelope to allow conditioned air from ceiling-located LAF units to directly sweep down through the lift and 'spill' back into the general room. The bespoke machine design enabled rubber stoppers to be lifted and tipped into a vial-filling feed chute at a discharge height of approximately 2,150mm. All aspects of the unit, controls and guarding were fully compliant with all national and international regulations and successfully achieved the customer's own Factory Acceptance Test and Documentation (FAT).
To achieve a controlled environment during lifting and tipping, Base Handling designed the unit with the lift mechanism and all other moving components contained within a special guarded and interlocked enclosure, which is sealed to prevent any ingress of external contamination. The product being handled is loaded into the system via a purpose-built delivery hatch and thereafter is accessed via glove ports. The pharmaceutical handling system is enclosed in a protective outer guard constructed from stainless steel box section and 12mm clear polycarbonate sheet. Each access hatch or door is independently interlocked with a pneumatic interlock switch to ensure a complete safety and product integrity.
The safety system was designed to be a no-stored-energy system so that the lifting carriage always returned to its resting position in a controlled manner even under disconnection or loss of the compressed-air supply. The whole unit is mounted on castors so that it can be easily manoeuvred into position for operation and removed for cleaning. The base frame is a fabricated structure constructed from stainless steel box section with two 100mm-diameter nylon fixed castors and two 100mm-diameter nylon swivel braked castors suitable for an aseptic environment.
The lifting hopper into which the stoppers are loaded was manufactured from grade 316 stainless steel finished to 0.3um Ra and all other surfaces were grade 304 stainless steel finished to 0.8um Ra. Andrew Pitt, sales director of Base Handling Products, said: 'While we are used to manufacturing systems for demanding applications including pharmaceutical and hazardous areas, this aseptic specification required a new design that provides a controlled environment without being too complex in operation, or for cleaning and maintenance.

The base frame is a fabricated structure constructed from stainless steel box section with two 100mm-diameter nylon fixed castors and two 100mm-diameter nylon swivel braked castors suitable for an aseptic environment.
The lifting hopper into which the stoppers are loaded was manufactured from grade 316 stainless steel finished to 0.3um Ra and all other surfaces were grade 304 stainless steel finished to 0.8um Ra. Andrew Pitt, sales director of Base Handling Products, said: 'While we are used to manufacturing systems for demanding applications including pharmaceutical and hazardous areas, this aseptic specification required a new design that provides a controlled environment without being too complex in operation, or for cleaning and maintenance.

Posiplan Gearbox Suits Industrial Applications
A modular design incorporating the flexibility of the Brevini planetary gear range ensure versatility and the ability to engineer solutions according to the application. Product lead time and costs also remain competitive, the company said. The gearboxes are able to accommodate up to 80,000Nm of torque; reduction ratios can reach in excess of 1:70,000 (starting at 1:12) with the inclusion of planetary stages. This means that the Posiplan range is suitable for use in applications where medium/low speeds and high torque are required, such as mixers, conveyors and crushers.
Using the hybrid gearboxes in a shaft-mounted configuration offers the flexibility of fitment in any orientation and can be used to replace high-wearing, high-maintenance, exposed transmission alternatives such as belts, chains and pulleys. It also helps to reduce costs when compared with worm and wheel transmissions; due to the efficiency of the Posiplan gearboxes, the demanded input power is reduced in comparison. The units are also lower in weight and production costs, making them price competitive.
There are two lines in the Posiplan range: the PH (planetary helical) and BPH (bevel planetary helical). The PH is said to offer advantages over traditional helical gear designs by offering a range of reduction ratios within one casing. Brevini said the PH offers a suitable solution for space- and weight-restricted applications. The BPH offers similar levels of performance but incorporates a bevel gear stage to provide a solution with perpendicular input and output shafts. Both lines deliver long life and high-efficiency operation through the specification of high-quality and adequately sized bearings.
Nitrile (NBR) shaft seals are supplied as standard, while alternative seal materials and designs (labyrinth and cassette, for example) are optionally available. Options and accessories include various output shaft designs, auxiliary drives and backstops as well as a number of input adaptations for all possible prime movers. The casings are all nodular-grade cast iron.

Moulded Bipolar Plates for Fuel-Cell Stacks
Bac2, which specialises in advanced polymers and fuel-cell components, will showcase moulded bipolar plates for fuel-cell stacks at the Hannover Messe exhibition on 4-8 April 2011. According to the company, which will be found on Booth D74 in Hall 27, the plates, which are made using the patented Electrophen electrically conductive polymer, reduce the cost of fuel cells because they can be moulded for high-volume production.
It is said to be economical to tool up and mould relatively small quantities of plates, sometimes just a few hundred, in order to realise economies of scale. The mould-flow properties of Electrophen mean that the plates do not need post-processing, such as surface machining or drilling, after moulding. Materials wastage is therefore minimal. Electrophen bipolar plates are available for high-temperature and low-temperature polymer electrolyte membrane (PEM), direct methanol, alkali and phosphoric acid fuel-cell stacks.
Unlike those made from metal, the plates are chemically inert, do not corrode, will not poison fuel-cell electrodes and are rugged enough to withstand harsh environments. They are made using a simple, two-stage, mix-and-mould manufacturing process. In addition to moulded plates, Bac2 supplies blank plates that can be machined for fuel-cell development work. Blank plates are available from stock.

ICs Drive Stepper Motors in Automotive Systems
The A4980 is identical to the A398,1 except for a low-voltage operation feature that will allow the IC to run down to a load-supply voltage of 3.3V (compared with 7V on the A3981). This low-voltage operation may be necessary in some automotive applications where the battery voltage during cold cranking can drop to a critically low level. The built-in current regulator can be programmed to operate in fixed off-time or fixed-frequency PWM modes, with several decay modes available to reduce audible motor noise and increase step accuracy.
In addition, the phase-current tables can be programmed via the SPI interface to create unique microstepping current profiles to further improve motor performance for specific applications. The current in each phase of the motor is controlled through a DMOS full bridge, using synchronous rectification to improve power dissipation. Internal circuits and timers prevent cross-conduction and shoot-through when switching between high-side and low-side drives.
The outputs are protected from short circuits and features for low load current and stalled rotor detection are included. Chip-level protection includes hot and cold thermal warnings, overtemperature shutdown, and overvoltage and undervoltage lockout. The A3981 and A4980 are supplied in a 28-pin TSSOP power package with an exposed thermal pad (package type LP). This package is lead (Pb) free with 100 per cent matt-tin lead-frame plating.

Power Management for Li-Ion/Polymer Cell Systems
Linear Technology has announced the LTC3675, an integrated general-purpose power-management solution for high-power single-cell Lithium-Ion/polymer cell systems. The device features seven independent rails, with I2C control, flexible sequencing and fault monitoring in a 28mm2 QFN package. The LTC3675 contains four high-efficiency synchronous step-down regulators, a high-current/high-efficiency buck-boost regulator, a synchronous boost regulator, a dual-string 40V-LED driver and an always-on LDO.
Pushbutton on/off/reset control, precision enable inputs and a power-on reset output provide flexible and reliable power-up sequencing. The LTC3675's I2C interface provides complete regulator control, status reporting and a maskable interrupt output. Quiescent current is 16uA with all DC/DCs off to maximise battery run time. The LTC3675's four constant-frequency current-mode buck-switching regulators are internally compensated, providing up to 1A and 500mA output currents, respectively, with complete I2C control.
Further, the buck power stages can be paralleled to deliver up to twice the output current with a single inductor. The buck regulators can operate in two different modes. In pulse-skipping mode, the regulator will skip pulses at light loads, but will operate at a constant frequency of 2.25MHz at higher loads. In Burst Mode operation, the regulator will burst at light loads for best efficiency and at higher loads will operate in constant frequency PWM mode for lowest noise performance. I2C may be used to control the device, enabling mode of operation, feedback-regulation voltage and switch slew rate.
The bucks have forward- and reverse-current limiting, soft-start to limit inrush current during start-up, short-circuit protection and slew-rate control for lower radiated EMI. The LTC3675's buck-boost regulator is a 2.25MHz voltage mode regulator designed to deliver up to 1A load current for a typical programmed output voltage of 3.3V. The regulator can be enabled via its enable pin or via I2C. The mode of operation (Burst Mode or PWM), feedback regulation voltage and switch slew rate can all be controlled via I2C.
The buck-boost regulator also features forward current limiting, soft-start to limit inrush current during start-up, short-circuit protection and slew-rate control for lower radiated EMI. The LTC3675's boost regulator is designed to deliver up to 1A load current for a programmed output voltage of up to 5V. Boost DC/DC enable, mode of operation (Burst Mode or PWM), feedback regulation voltage and switch slew rate can all be controlled via I2C. The boost regulator has forward and reverse current limiting, soft start to limit inrush current during start-up, short-circuit protection, slew-rate control for lower radiated EMI and true output disconnect when in shutdown.
The LTC3675's constant-frequency, current-mode 40V LED driver can regulate up to 25mA of current through each of two series 10-LED strings. LED enable, 60dB brightness control and up/down gradation are programmed using I2C. The LED driver can be configured as a general-purpose high-voltage boost converter with a 1.6A (typ) switch current limit. Given its high duty cycle operation, it can boost from below 3V to up to 40V output at 55mA. The LTC3675 is available in a thermally enhanced 0.75mm 44-pin 4 x 7mm QFN package.

IC Offers Ambient Light and Proximity Sensing
The programmable proximity detection enables continuous measurements across the entire range. The device can be put into a low power mode in between ambient light sensing and proximity measurements, providing low average power consumption. Features include programmable analogue gain, programmable integration time and programmable interrupt function with upper and lower threshold. The device offers resolution up to 16-bits and high sensitivity. It also offers a dynamic range of up to 1,000,000:1. Proximity detection is the ability of a system to sense objects within a specified distance.
It can be utilised to determine when an object is approaching the system, or when the system is approaching an object. Infrared is not visible to humans and is therefore a suitable choice for proximity detection. The infrared LED emits light towards an object, and if a target object is present, infrared light will be reflected towards the sensor. The sensor gathers the energy and determines if the amount received is sufficient to declare a 'proximity event'. The specified range that determines a proximity event varies depending upon the application.

Power Station Installs Verder/Naiad Dosing System
'The addition of ferrous iron to seawater causes an effective protective film to establish as Fe2+ is oxidised to colloidal iron, which adheres to the inside walls of the tubes,' he added. Mike Heap, sales director at Verder, said: 'With the Naiad copperas actuator now in place, the process is automatic and requires little manual intervention. 'It has performed well since it was installed some months ago and has enabled one-tonne loads of copperas crystal to be safely employed. 'At Kilroot, the one-tonne bags are lifted into position above the saturator with a crane system and copperas crystal is progressively fed into the reception tank by releasing a draw cord at the base of the bag.
'In Naiad's process, the crystal is continuously dissolved in water and dosed to the works inlet by dedicated Verder Dura pumps, with similar pumps being used to generate the dilute solution. 'The process is regulated by a digital dose controller, which is set up and operated by way of a touch-screen HMI. 'The site operator simply enters the weight of chemical delivered to the unit and starts the dosing process by processing the start button on the dosing panel.

Pressure Regulator for Pneumatic Control Systems
Midland-ACS has launched the OPD Stemsaver, a high-integrity pressure regulator for pneumatic control systems used for valve actuation in the oil, gas and other processing industries. The device guards against any failure of the filter-regulator that controls compressed-air system pressure by providing dual-redundant over-pressure protection. It ensures that any downstream actuators for controlling process valves cannot be accidentally exposed to dangerous over-pressures that could be high enough to shear a valve stem or cause other damage.
The device provides plant and automation engineers with a high-integrity safeguard against a failure mechanism that could lead to costly process shutdown or injury. Pneumatic actuation is widely used in process automation systems for controlling and sequencing valves. Automated control valves are particularly common in hazardous areas, such as offshore platforms and refineries. In hazardous areas, actuated valves are often elements of a plant's emergency procedures, such as the safety instrumented system (SIS) that controls emergency shutdown (ESD).
Depending on the emergency and type of process, valves may be automatically closed, to stop media feeding a fire, for example; parts of the plant may be isolated, or media might be vented to atmosphere via an emergency system vent (ESV). Pneumatic actuation systems typically use a single filter-regulator component, and the failure of this component can expose downstream devices to pressures as high as two or more times the norm. This can be enough to cause significant damage, even providing an actuator with enough torque to shear a valve stem.
Midland-ACS developed OPD Stemsaver following a request from an engineering, procurement and construction (EPC) company working for a North Sea oil producer. A failed filter-regulator had led to the cover of a pneumatic actuator being blown off, leading to costly downtime of operations. The company's OPD Stemsaver design avoids this possibility by providing a dual-redundant pressure regulation facility with one diaphragm regulator, coupled to a spring-tensioned poppet valve. The use of these two different regulation mechanisms provides additional reliability.
As standard, OPD Stemsaver can be set to regulate pressure in the 4-8 bar (58-116lb/in2) range. The device is supplied as a single compact unit, fabricated in 316 stainless steel to meet the anti-corrosion requirements of environments such as offshore platforms and process plants handling harsh media. In use, the secondary regulator is set to operate at a slightly higher pressure than the primary regulator. If the secondary regulator is activated, a reset button also automatically pops up.
This can be linked to a proximity switch to provide feedback to the plant's distributed control system (DCS). OPD Stemsaver is available from Midland-ACS as an individual component. It is also compatible with the company's modular pneumatic control manifold - Impact. This is a universally compatible interface block that mounts directly onto valve actuators and accepts a range of field-proven pneumatic components.

Steam System Helps GTM get Biosolids Treatment
Steam and hot-water systems from Spirax Sarco are helping Anglian Water treat sewage sludge at two new biosolids treatment works in Kings Lynn and Great Billing. The projects are two of four schemes planned by the utility company to reduce biosolids volumes, increase quality and generate energy in the process. This process will not only make the centres self-sufficient in electricity but any surplus will be exported on to the national grid.
Spirax Sarco was brought in to provide consultancy on the specification, design and installation of the steam systems for both sites. A number of Spirax Sarco specialists in condensate recovery, steam trapping and water treatment worked in partnership with the projects' contractors to design an easily maintainable system with minimal downtime. Spirax Sarco supplied boiler-feed tanks and all the steam equipment associated with the standby, dual-fuelled steam boilers at both Kings Lynn and Great Billing.
These boilers are used during start-up and also during very cold weather when they are sometimes needed to supplement the steam from the CHP plants' waste-heat boilers. The company also supplied steam-to-hot-water Easiheat systems to provide standby hot water for both sites. The Spirax Sarco systems are predominantly used during start-up, providing steam and hot water to drive the treatment processes. Both projects have been built by Imtech as part of the Galliford Try Imtech Process (GTM) consortium. The Kings Lynn plant has now been operating for almost three years, processing sludge equivalent to around 19,000 tonnes a year of dry solids.
The Great Billing plant will treat 38,700 tonnes of solids a year and was commissioned in late 2009 early 2010. Although they vary in size, both sites operate similar processes to treat the sewage sludge or biosolids, which are a byproduct of waste-water treatment. First, the sludge is heated by hot water to 42C and hydrolysed to break up some of the bigger molecules. It is then steam heated to 55C to pasteurise it and destroy any pathogens. Microorganisms continue to break down the pasteurised sludge even further in an anaerobic digester, where they convert a substantial proportion of it into biogas.
This biogas fuels an onsite combined heat and power (CHP) plant, which generates electricity, steam and hot water. The result is a 40 per cent reduction in the volume of sludge. It is also free from pathogens such as Salmonella and E coli and can therefore be used safely by farmers as a fertiliser substitute.

Optical Laser-Based Sensors for Pulley Inspection
Optical laser-based sensors from Micro-Epsilon are playing a vital role in inspecting the quality of manufactured pulleys. The high speed and high resolution of the sensor enables the tip diameter of the pulleys to be measured accurately and rapidly in two planes. Pulleys are used in a variety of applications and are required to meet strict manufacturing quality standards.
As pulleys often need to operate in applications where high torques and rotational speeds are present, any deviations in the geometrical dimensions of the pulley during manufacture can very quickly lead to defects in the shaft bearings during operation. Dimensional stability and centricity are therefore critical quality factors. This is why pulleys need to be tested thoroughly after they are manufactured.
Measurement technology service provider QS-Grimm has developed a special-purpose measuring system for inspecting the quality of manufactured pulleys. Several testing stations have been installed to inspect the quality criteria of manufactured pulleys. These measuring stations each comprise four Optocontrol 2500 optical micrometers supplied by Micro-Epsilon. These sensors measure the geometrical dimensions and verify the diameter of the pulleys in two locations.
Two sensors each record the tip diameter on a plane to the left and right of the pulley. Due to their ability to rapidly evaluate the measurement data in one plane, the diameter of the tip can be determined accurately to a resolution of 0.1um. Optocontrol 2500 is a laser-based measuring system with integrated high-resolution CCD camera. The Thrubeam micrometer measures the dimension of an object or the position of an edge by using the shadow-casting principle.
The data obtained with various, selectable measuring programmes, is output via analogue and digital interfaces. Due to its high measuring speed, accuracy and resolution, the laser micrometer is suited for precision measurement and inspection tasks on moving products in production environments. The Optocontrol 2500 consists of a sensor unit and a controller.
The sensor unit comprises a laser light source (transmitter) and a CCD camera (receiver). A parallel light curtain is produced with the laser light source. The CCD array in the receiver measures the contour formed by shadow casting of the measurement object with high accuracy. The sensor unit is controlled and evaluated by an intelligent controller with graphical display for operation and display of measured values.

TUV SUD Centre will Test Industrial/Consumer Goods
To mark 21 years in the business, TUV SUD Product Service is launching a CE Marking Centre of Excellence at its Warwickshire laboratories. TUV is recognised in the industry for its own stringent 'TUV octagon' compliance mark, which is part of ensuring what people buy is safe and reliable. More than 29,000 TUV octagon marks can be found on a variety of products, and companies that use it include Hewlett Packard, Black and Decker, Tandberg and Dyson.
The TUV octagon mark goes beyond the one-off type testing required by CE marking, as a product must not only comply with the relevant standards, but additionally, manufacturing facilities must pass an annual audit and specific claims about the product's performance must also be proven. According to the company, the TUV mark carries great credence as it is tough to get and consumers in Germany will think twice about buying a product that doesn't have the octagon mark on it.
TUV SUD Product Service was created by German safety company TUV SUD in 1989 and now has an international network of more than 15,000 auditors and engineers in 600 locations worldwide. Over the last two decades TUV SUD Product Service has established a large one-stop testing shop as it has a fully integrated, single-site facility for EMC, environmental and telecoms testing.
In the last 21 years it has tested a wide variety of products including the new electric Mini, Formula One modules and Tetra communication devices for the emergency services. It also works for many European countries as product-safety surveillance officers, as well as working directly for retailers.

Gauge can be Configured for any Shape of Tank
The gauge provides a corrected 4-20 mA output proportional to contents, as well as Modbus RS485 communications. Features include latching pump-control options, High Alarm and Bund Alarm all in one low-voltage unit.
Pipeline Welder has Smooth and Quiet Operation
The SAE-300 supplies 300A of welding power at 60 per cent duty cycle with a maximum output of 350A. This machine's capabilities allow for an operator to stick weld up to 7/32in electrodes and arc gouge with up to 1/4in carbons. The unit is equipped with a 32.7HP Perkins 404D-22 four-cylinder water-cooled diesel engine, which runs at 1,800rpm to ensure smooth, quiet operation with long life. Standard oil pressure, engine temperature and battery-charging gauges allow operators to monitor vital engine performance indicators at a glance.
The 60.6-litre fuel tank allows operators to work an extended day without refuelling. The machine's pure DC-generator welding output is produced from a proven rotating armature/field coil system that has been manufactured for many years by Lincoln Electric. The SAE-300 can also be used to power tools, grinders (up to 9in) and lights through the machine's 115V AC or 230V AC duplex receptacles, which supply up to 3,000W of auxiliary power.
For a limited time, Lincoln Electric is running a special promotion for buyers of a new SAE-300. With the purchase of a new machine, owners have the opportunity to order a free durable brass nameplate personalised with their name and the unit's serial number. Instructions on ordering the custom nameplate are in the information packet enclosed with each new SAE-300.
Vibratory Bowl Feeders Used for Toothbrush Covers
As the orientation required at the outlet was the same, the orientation tooling in each of the bowls had to be made differently in order to match with their clockwise and anti-clockwise directions. Against a required speed of 40 parts per minute, Elscint achieved a speed of 50-55 parts per minute. Additionally, a single linear track of 800mm length with both the chutes mounted on it was used to convey the parts forward. Elscint used an air-jet system to orient the parts. A table made of aluminium-extruded sections mounted on castor wheels was also provided.
Edwards' Vacuum Pumps Improve Lab Reliability
As a result, scientists can gain information from materials with different dispersion phases, such as oils, polymers, fats and food stuffs. Quorum Technologies was looking to increase the reliability of its chambers and approached Edwards to provide oil-free pumps with minimal vibration and maintenance requirements. Quorum's PP3000T cryogenic preparation chamber is turbomolecular pumped and includes tools for cold fracturing, controlled sublimation and specimen coating.
The specimen can then be transferred onto a stable SEM cold storage for observation. It is highly automated, easy-to-use, column-mounted, gas-cooled cryo preparation system suitable for most makes and models of SEM, FE-SEM and FIB/SEM. Edwards recommended its compact EXT75DX turbomolecular vacuum pump, which uses multi-stage axial flow turbines combined with magnetic and ceramic bearings to provide reliable, hydrocarbon- and vibration-free ultra-high vacuum with ultimate pressure down to 5 x 10-9 mbar.
Software for Extended Reports and Parts Management
The revision process can now be controlled for individual pages through the page filter as required by the respective project phase. At the same time, certain types of pages, such as cover sheets, tables of contents and revision directories, can be excluded generally from completion. A clearer structure is provided in the process by using colours and symbol forms for different identifications. All project participants recognise at a glance whether project information has been added, modified or deleted.
New form functions with 'conditional areas' open up new options in the definition of project reports. Eplan forms can now be formed dynamically so that different types of items can be reported in a common form. This form reacts to the corresponding item properties by using special partial tables for reporting, displaying suitable product graphics or special symbols and, for example, highlights safety-relevant items through a different colour.
The resultant reports not only ensure that the required overview of the project data is available in the engineering phase, but also makes the decisive information available in a compressed but well structured form available for all the downstream project phases. In maintenance and servicing, the new PDF/A format guarantees long-term access to cross-discipline project documentation.
In accordance with the ISO 19005-1 standard, this format is a standard for the long-term archiving of electronic documents. In particular, this archiving also provides added value in light of the requirements of the Machinery Directive 2006/42/EC that requires a complete documentation for at least 10 years. At the same time, PDF/A supports paperless workflow and thus simplifies the complexity of large projects.
