Arm assembly consisting of four flexible tubes controlled by a four-way hydraulic or pneumatic valve can bend in any direction. The flexible arm could be used for probing areas that cannot be reached by ordinary tools, handling hazardous materials, and for graph recording.
Liquid cavitation studies in circular pipe bends
Selection of accelerometer positions to predict system stability of lateral acceleration-bending coupling in large flexible booster
Effect of cooling rate on ductile-brittle bend-transition temperature of chromium wire
Technique uses a stiff medium in the annular space between inner and outer pipes of jacketed piping in transfer lines. The process eliminates splitting and welding and makes possible the use of standard pipe-bending tools.
Heat resistance testing of titanium aluminum tin alloys by centrifugal bending method
Effect of quenching on ductile-brittle bend transition temperature of chromium wire
Effect of quenching on ductile-brittle bend transition temperature of Cr-35Re wire
Thermal bending plus twist of thin-walled cylinder of open section with application to gravity gradient booms
Fatigue crack propagation in thin plates under fluctuating plane extension and cylindrical bending
Mathematical model representation of bending and slosh phenomena in the Saturn vehicle results in linear second order differential equations. Improved technique was developed to provide a real-time digital solution of the equations. The technique may also be applied to nonreal time digital simultations, resulting in savings of digital computer time.
