• Torque Measurement Primer (.pdf)
  factor 3 devices involve high variable shock or light reversing loads. Examples. incl ude crushers, single-cylinder reciprocating pumps, vehicle drivelines and hammer mills. Lev el 4 devices are the most severe and involve heavy to full torque reversals including. reciprocating compressors. Next you...
• Optimize Terephthaldehyde Reactor Operations (.pdf)
  High-fidelity predictive modelling was used to design a high-performance multitubular reactor for production of terephthaldehyde (TPA). This involved coupling detailed catalytic tube reaction models with a CFD model of shell-side coolants. The resulting hybrid model was used to determine the effect...
• Gas-powered electronics
  and the pace of improvements slowing. The device that uses a chemical reaction to generate electricity is called a cell. Batteries consist of two or more electric cells connected in a manner to boost the voltage or current available from a single cell. Cells that generate power through one-way chemical...
• Predicting Seal Life with FEA
  Simulating aging and chemical effects can help determine how long seals will last. Finite-element modeling is an attractive alternative to physical testing for predicting seal life, particularly when aging poses major concerns and seal replacement is expensive. For years, seal manufacturers...
• Heading toward the hydrogen economy
  highpurity hydrogen at pressures to 363 psi. The Hogen 40 hydrogen generator from Proton Energy, Wallingford, Conn., manufactures 99.9% pure hydrogen at 200 psi. Hydrogen holds fantastic promise as a plentiful, clean-burning fuel and an eventual replacement for gasoline. Environmentalists like...
• Adhesion, Adhesion Failure, and BONDiT
  filled with glass fiber (mineral) for structural material replacement of aluminum and steel brought on the discovery of another phenomenon. Prolonged exposure to moisture severely degraded the composite's strengthto- weight ratio. The loss of strength demonstrated the power of intruding water to debond...
• Controlling corrosion, particles in metal etch-and-strip cluster tool systems
  Shams Tabrez, Changhun Lee, David Yang, and Yun-Yen "Jack" Yang, Many benefits can be derived from integrating two metal etch and two strip process modules on a single platform. For example, an increase in throughput per square foot of floor space is an important advantage because of the spiraling...
• MICRO: Wet Surface tech
  in selectivity of approximately 10:1. The etch-rate data in Figure 6 for both Si3N4 and SiO2 processed at 130 C indicate that the rates are essentially constant over time. Since etch processes generally tend to be diffusion limited, the mass transport of reaction by-products and the replacement...
• Analysis of Impurities in Polymer-grade Ethylene, Propylene and 1,3-Butadiene
  Impurity in On-Line Applications. Each of the proprietary detection tapes reacts instantly to. Figure 2: Modern Dry Colorimetric Detection: the target gas for fast results that are visible due to the color. The C.I. Analytics System. reaction. For example, it takes less than 90 seconds to detect...
• Fluid Handling Achieve optimum centrifugal pump performance Food Processing
  to satisfy even the most difficult conditions faced by centrifugal pumps. As an example, thrust-type bearings (to support axial loads created by hydraulic forces in the pump) include various versions of angular contact ball bearings that suit many applications: Single-row 40 angular contact ball...
