Build Material Increases 3D Printed Model Demand

The Realization Group is using a combination of Z Corporation's ZP150 build material and the multicolour 3D ZPrinter450 to meet demand for models with richer colours and improved mechanical strength. 'Purer whites are especially important for architects, who traditionally prefer white models early in the design process so they can consider design, massing and space without the distraction of colour,' explains Rafael Tapanes, founder of the multidimensional architectural visualisation firm. 'Although earlier generation bone-white models are acceptable, customers have long been asking for pure white,' he added. Architecture is a key sector for Realization Group, which helps clients breathe life into abstract concepts. Finely detailed physical massing models are created rapidly and cost effectively using the recently installed ZPrinter450 multicolour twin-head 3D printer. 'Speed is the key,' said Tapanes. 'I can take an order for a model today and deliver

Feedthrough System Withstands Up To 450F

ITT Interconnect Solutions has announced a high-temperature electric power feedthrough system for submersible pumps specifically designed for operation with conductor temperatures up to 450F (230C). Such a severe operating environment places significant demands on the individual components and stresses sealing elements of the system. ITT Interconnect addressed these issues by re-engineering the power feedthrough, incorporating a keying system and a new sealing system. The engagement system between the BIW high-temperature feedthrough and the mating surface connector includes the Metal-Lok keying system, which prevents rotation of the surface connector should it be inadvertently turned or mishandled. In addition, seals between individual parts of the BIW high-temperature feedthrough are protected by a new sealing system, which can withstand extremely high temperatures, preventing the ingress of downhole fluids. Exterior seals to the hanger and top flange have been fitted with high-temp

ACI De-Duster Allows Safer Clean-Down Process

An Air Control Industries (ACI) Jetblack personnel de-duster has replaced a dangerous compressed air cleaning process at a Steetley Dolomite works. The Whitwell Works of Steetley Dolomite quarries and produces magnesium limestone products for the steel, refractory and agricultural industries. After the limestone is quarried, it is crushed, sized and processed to produce various products for applications such as steel furnace manufacture and repair, steel production, refractory products and agricultural soil improvement. The processing of the limestone to produce these products results in the creation of a lot of dust around the plant, which gets deposited on the overalls of workers on site. To de-dust themselves, although advised frequently not to because of the very real danger that it poses, many of the staff would clean their overalls down with compressed air. Posters about the risks and verbal warnings from the safety leader for compressed air, John Collins, seemed to do little to

Schaffler Agrees Uniair Cooperation With ABB

Schaeffler and ABB Turbo Systems AG have signed a cooperation agreement with regard to the Schaeffler valve-control system, Uniair. The collaboration agreement will see ABB contribute its knowledge of efficient, single- and two-stage turbocharger technology, as well as marketing and sales of large, high-performance engines. The cooperation applies to units with a performance of 400kW (544 PS) per cylinder or higher. The applications of these large engines are typically in marine, machinery and stationary operation. The advantages of the VVT system in conjunction with high-pressure turbocharging are in the fields of emission- and fuel-consumption reduction and in the improvement of the start, part load and acceleration behaviour. The Uniair fully variable, hydraulic valve-control system is behind the VVT system and enables the variation of valve timing and lift. The Alfa Mito 1.4 Multiair is the first vehicle to utilise this technology, which is branded 'Multiair' by Fiat. The

Motor Technology to supply TPM pumps

Fuji Techno Industries has appointed Motor Technology of Stockport as its sole European agents to provide sales and servicing of its specialist triplex plunger metering (TPM) pumps. TPM pumps are used in metering applications where a predetermined volume of liquid is pumped into a process or system with a very high degree of accuracy - better than 0.1 per cent in the case of water - even under variable pumping conditions like discharge pressure, temperature or viscosity of fluid. The pumps have three cams that discharge the required volume of fluid from three cylinders at a continually constant rate. The design of each plunger incorporates six phases of movement at increments of 60deg within one revolution of its respective cam. The flow rate at the suction side is kept constant to minimise the possibility of cavitations and pulsation. The pump's cams are designed to enable the plungers to deliver a constant volume of fluid from the three cylinders. Fuji Techno's TPM pumps

DEK OTS Clamping Secures Printed Circuit Boards

DEK has launched its Over Top Snuggers (OTS) substrate clamping technology. Securing printed circuit boards firmly in place ready for processing, the flexible technology is designed to ensure high-quality printing for enhanced end-of-line yield. OTS clamps the board flat before enabling finite snugging and clamp control for precise board location. The board is pulled down flat to enable a strong vacuum tooling contact and the clamps are then pulled away from the board top face surface to allow close-edge printing. By optimising edge-printed paste deposits, this process enhances yield potential. The OTS system automatically adjusts for variations in board thickness, eliminating setup requirements between production batches and runs and removing the need for manual intervention. The clamps will also automatically adjust for out-of-parallel boards. The technology uses the Instinctiv V9 user interface software to adjust and store clamp and snug pressure via a touch-screen interface. OTS i

Infineon Adds LED Drivers To Energy-Saving Range

Infineon Technologies AG is extending its portfolio of energy-efficient lighting ICs with a range of low-cost linear LED drivers. The BCR320 and BCR420 product ranges address the market for energy-saving and environmentally friendly light-emitting diode (LED) lighting solutions. Designed for driving 0.5W LEDs with a typical current of 150 to 200mA, these LED drivers feature a negative thermal coefficient, contributing to a long lifetime of LEDs and a digital interface for a pulse-width modulation (PWM) signal for dimming. The BCR320 and BCR420 LED drivers are tailored to address deficiencies for 0.5W LED applications, providing a low-cost solution with a small form factor. With both devices, the use of inductors, capacitors and free-wheeling diode can be avoided. The elimination of electrolytic capacitors can also contribute to the extended lifetime of the LED system. The BCR320 products are designed for a peak output current of up to 300mA. For continuous operation, a maximum nominal

ITT Introduces Packer Feedthrough System

The BIW field-attachable packer feedthrough system launched by ITT Interconnect Solutions is designed to provide a faster method of passing power cables through packers. Consisting of a field-attachable feedthrough connector, a mating attachable cable connector, a cross-over adapter and related hardware, this system allows the connector to be installed on the top side of a packer using a cross-over adapter, eliminating the need for splicing of down-hole cables. Potential stress on the cable is eliminated as the packer feedthrough includes a completely variable threaded adjustment system, allowing vertical adjustment of up to 3in (76mm). When appropriate, it is possible to install the termination contacts on the cable conductors before the cable is passed through the packer. This may reduce the amount of work an installer is required to carry out in a vertical position over an open well. Electrical specifications include voltage ratings of 5,000V AC, 140A current, pressure up to 5,000p

ABB Drives Reduce Swimming Pool Energy Bills

ABB drives have helped a UK holiday park operator save GBP77,000 a year on energy bills for its swimming pools. Bourne Leisure, which owns brands such as Haven, Butlins and Warner Leisure hotels, has swimming pools at a number of its properties. ABB Drives Alliance partner APDS was asked to investigate the energy-saving potential for the swimming pools and a trial was conducted on two of the three filtration pumps at Bourne Leisure's Devon Cliffs site. The pump was monitored for a period before a variable speed drive (VSD) was installed. Monitoring with a temporary VSD fitted demonstrated that considerable energy savings could be made. The direct-on-line pumps were working at 50Hz drawing an average of 30A. When the drive was introduced, this figure was reduced to 23A during the day and 15A at night, with no effect on water quality. APDS and ABB recommended fitting VSDs to the pumps feeding the pool filters. The pump filters operate by trapping dirt and debris in the sand filte

Q-Sys Provides Custom-Designed Motion Systems

Q-Sys offers a complete design-and-build service for all types of precision motion and positioning systems. Q-Sys aims to fill the gap between standard catalogue motion products and real-world applications. Instead of trying to create a solution for a complex motion task from components designed for mass production, Q-Sys enables engineers to obtain exactly what best suits their needs - bespoke, high-accuracy motion equipment. By exploring the real requirements of the application, Q-Sys said its engineers can offer high-performance but cost-effective solutions to today's demanding motion systems needs. This may result in a custom design to directly meet the customer's specification. However, more often than not, the solution will use one or more elements from previous designs. These are carefully selected to ensure the most cost-effective solution. The company said that this technique has proved successful, not only for one-off special-purpose systems, but also in producing th

Verderflex Dura Pump Ensures Bubble-Free Printing

Peterson Packaging, a Danish printing company, has selected the Verderflex Dura peristaltic pump to gently handle water-based ink. Transferring ink from storage containers to the rollers on printing machines was proving problematic for Peterson. Air diaphragm pumps were originally responsible for the job, but had proved unable to handle the water-based ink gently enough. As a result, bubbles formed in the ink, ruining the packaging, creating excess waste and adding expense. To resolve the problem, the company decided to look for a gentle-action pump to ensure bubble-free ink. The chosen design also needed to be both cost effective and sufficiently compact to fit into the limited space available. With the Verderflex Dura peristaltic pump, ink is completely contained within the pump's hose, which is compressed by a rotating roller. On restitution of the hose, the resulting vacuum draws in more liquid, creating a gentle and accurate pumping process. The design eliminates any danger o

Insertion Probes Monitor Bioproduction Process

Stratophase has collaborated with the Centre for Process Innovation (CPI) to develop an insertion probe variant of its Spectrosens system. Enabling real-time monitoring of the bioproduction fermentation process, the multi-output Spectrosens insertion probes track compositional changes and monitor temperature in the liquid. Multiple discrete readings can be taken simultaneously at numerous locations, providing more reliable measurements and a reduced chance of false positives. As a result, the entire fermentation process can be precisely monitored to ensure reproducibility and clear determination of the desired end-point. The Spectrosens system sensors can be placed throughout the production process and networked via the control and analysis unit. Using only light at the point of measurement, the sensors are intrinsically safe and spark free, removing any chances of ignition. The insertion probe fits standard ports for dissolved oxygen (DO) and pH probes, enabling ultra-high resolution

Ansys Software Helps Ferrari Improve Comfort

Italian car manufacturer Ferrari is using software from Ansys to optimise automobile design and performance. Ferrari is using software from Ansys to predict thermal comfort in a vehicle's interior. In order to assess comfort qualitatively and quantitatively, the car manufacturer worked with Pisa University in Italy to define thermal comfort indices and to evaluate the general aspects of thermal comfort. Since an experimental approach was not practical, the investigating engineering team used fluid dynamics software from Ansys to perform the calculations. According to Giovanni Lombardi, professor of aeroplane aerodynamics and vehicle aerodynamics at Pisa University, the Ansys engineering simulation software rendered accurate and reliable results. The research team based its resulting 'global thermal comfort index' on several local indices: the thermal equilibrium of the human body, discomfort caused by drafts and horizontal and vertical temperature gradients. Various facto

CNC Router Reduces Time To Market

A manufacturer of personal care products has saved money by switching to a low-cost computerised numerical control (CNC) router that can produce point of purchase displays internally. The manufacturer employed contractors to produce displays but there were delays in getting new designs to retailers and the cost of producing them was continually rising. The company made the decision to create its own displays and searched for an inexpensive, yet easy-to-use router that had the capability to produce plastic and wood components to high levels of accuracy. It opted for the Isel router, which has allowed the company to design and create new display designs in a single day. Isel's router has features readily found in more expensive machines such as ball screws and servo motors. This manufacturer is saving money on its outgoings and can now turn on immediately to meet the ever-changing design demands of the retail market. Ball screws have a few key advantages over racks: they don't ha

Imatek Installs Second 100KJ DWTT In Korea

Imatek has successfully installed a DWT40-100 drop weight tear tester (DWTT) at Hyundai Steel in South Korea. This follows the installation of a similar high-capacity machine at Posco Steel in Korea in 2004. Both machines provide impact energies of up to 100,000 joules. Although the DWTT test is typically used to measure the fracture characteristics of steel used in the construction of steel pipe for the gas-and-oil industry, Hyundai will also use the new machine for performing tests on steel used in ship-building applications. Hyundai's steel products are used globally in applications such as railway lines, bridge-support mechanisms and power-transmission towers. Hyundai Steel operates three production facilities in South Korea and one in China, from which it produces about 10 million tons a year. The use of higher-grade steels in the oil, gas and manufacturing industries is creating the need for a new generation of specialist impact testers. Imatek offers a range of DWTT systems

Rittal's PSM Measures Power Consumption Per Socket

Rittal has extended its Power System Module (PSM) range to allow the power consumption of individual servers and peripheral hardware to be measured per socket. New plug-in modules for PSM rails record the individual currents for each socket and show the power consumption of the devices connected, via three coloured LEDs on the right-hand side.  A second LED on the left-hand side of the outgoing slots provides an overview of the overall power of the module. The presentation logic is automatically adjusted to the mounting position to rule out any misinterpretation. Colour coding follows the traffic-light principle: green LEDs indicate that other equipment may now be connected safely; amber indicates increased current on the module and that before any other equipment is connected its installed load needs to be examined; red indicates that another consuming device would trigger the overloading of the power supply.  Values can also be viewed on a digital display, enabling administrators to

Cobham Software Performs Lightning Strike Tests

Cobham Technical Services has announced that its Opera electromagnetic design software has been used in an aircraft lightning strike simulation project. Lightning strike tests of a helicopter at Eurocopter's Donauworth facility have verified the accuracy of finite element analysis techniques for characterising the electromagnetic behaviour of complete and custom-cabled modern aircraft structures constructed using advanced composite materials. The exercise was performed using the Opera software as a final element of the company's work for the ILDAS (In-flight Lightning Strike Damage Assessment System) project.  Simulation of the ILDAS tests highlighted how finite element techniques can generate accurate models of complex assembled airframes and simulate the effects of lightning strikes rapidly - in around a day on a standard office PC - to help developers evaluate and optimise lightning protection measures during the design cycle. The industry's current certification agains

WEG Motors Drive Brazilian Theme-Park Attractions

WEG motors, inverters and soft starters are allowing the safe operation of equipment at the Beto Carrero World theme park, located in Santa Catarina, Brazil. Most of the equipment at the BCW uses WEG motors, inverters and soft starters for its motive power. For example, electric motors provide the drive functions for the rides and attractions. WEG products are also used on water pumps, compressors and other ancillary equipment. Hugo Loth Neto, the operations director of Beto Carrero World, said one of the main problems was the development and assembly of the drive centre of the big wheel. He explained: 'It has four motors, each one of 7.5HP. 'Another challenge was the development of the Water Empire project, with six motors of 150HP in the water pumps, a wet transformer of 1,000kVA and a dry one of 1,500kVA. 'In addition, the latest attraction of the park, the rollercoaster Firewhip, also relies upon WEG equipment: it has a static AC/DC converter of 130kW 380V, with a D

Pitch Gears With Intelligent Shaft Sealing

Simrit has developed a radial-shaft seal system featuring a leakage sensor that allows for telediagnosis of the shaft seal and automatically sends a signal when the seal's wear limit is reached. With the help of these intelligent shaft seals, Wittenstein alpha has maximised the service life and service intervals of its pitch gears for rotor adjustment. Pitch gears are key components in wind turbines around the world. They are used to adjust the pitch of the rotor blades, which in turn changes the aerodynamic efficiency of the turbine. Thanks to pitch gears, wind turbines can be operated at the optimum pitch until the rated power of the generator is reached. If the maximum generator torque is exceeded, the speed is adjusted by changing the pitch of the rotor blades. If performance remains constant, pitch gears allow wind turbines to operate continually at the optimum operating point. One pitch gear per rotor blade is attached directly to the hub by screws. Wittenstein alpha has opt

Accelerometers Obtain Hazardous-Area Certification

Wilcoxon Research has announced an additional intrinsically safe certification in accordance with IECEx requirements for six general-purpose accelerometers. The six accelerometers were approved for use in Class I Zone 0 hazardous areas. Tom Smith, vice-president of sales and marketing, said: 'These vibration sensors were previously approved as intrinsically safe by certifying agencies recognised in the US, Canada and Europe. 'Condition monitoring is growing in popularity across the world and the IECEx certification will help us better serve customers in other regions,' he added. Six general-purpose accelerometers, with a sensitivity of 100mV/g and a +5 per cent sensitivity tolerance, were certified as intrinsically safe in accordance with the requirements of the IECEx standards. The standard top-exit model is the 786A-IS. The standard side-exit model is the 787A-IS, which is also available with a metric M8 mounting stud (model 787A-M8-IS). The 780A-IS is a compact sensor.

Pam-Comfort Helps Renault Design New Seat

Renault has used ESI's Pam-Comfort system for the preliminary design of a new seat. ESI's Pam-Comfort software offers a scalable and customised solution dedicated to virtual manufacturing and virtual testing (static and dynamic) of the soft parts of a seat. Virtual seat prototyping consists of several chained simulated steps ranging from seat manufacturing and occupant static seating, to occupied seat NVH (noise and vibration), where the stresses resulting from each step are needed for the next one. The chaining is necessary to accurately predict the behaviour of the seats under numerous loading conditions (trimming, dummy loading, various human anthropometries and vibrations) and for various design changes (materials and shape). At Renault, where the full virtual seat prototyping methodology is being deployed, an important step after the preliminary design of a new seat is the virtual testing of the dynamic comfort performance using Pam-Comfort. To accurately predict seat com

DS Refrigerant Dryers Reduce Energy Consumption

Boge has brought out a range of energy-saving refrigerant dryers. The DS series features components used in compressed-air drying. Optimally dimensioned components assure reliability and efficiency, even in the most demanding conditions. The DS series dryers also constantly adapt to changes in ambient and volume flow to ensure dry compressed air is always delivered. At the same time the intelligent heat-exchanger system creates a lower pressure drop when compared with conventional systems. This low-pressure drop means that the compressor generation pressure can be reduced, with each 1 bar pressure reduction translating into a six per cent energy saving. By ensuring the lowest possible pressure loss, a high level of energy efficiency can be achieved. As the energy consumption of the compressor is greater than the dryer, these savings have a much larger impact and so increase the efficiency of the compressor. It is estimated that over a five-year operating period the purchase price of a
