Endevco Corp., San Juan Capistrano, CA, has completed what it claims to be the first available cold-gas shock tube that can effectively analyze the response of a pressure transducer. The device, along with its computerized analysis system, is designed to check the accuracy of pressure transducers used in turbine engines installed in aircraft, electrical power plants, and other industries. Engineering students from Texas Christian University (TCU) developed the shock tube in collaboration with Endevco engineers. The two-semester-long project involved researching shock tubes built and applied to pressure-transducer testing since the 1940s. Research included acquiring data analysis software and hardware to process the pressure-transducer signals resulting from the shock-tube environment. National Instruments' LabVIEW helped generate results used by the TCU team. The 12-ft-long x 3.5-inch-diameter shock tube, using helium as the driver gas, can be pneumatically or hydraulically activated. FAX (714) 661-7231.
Fifty-six-year-old Pasquale Russo has been doing metalwork for more than 30 years in a tiny southern Italy village. Many craftsmen like him brought with them fabrication skills when they came from the Old World to America.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
