Gasket of a commercially available plastic material is interposed between the mating surfaces in axial joints where a hard and a soft metal are in intimate contact under stress conditions. This eliminates the fretting problem and is quicker and less expensive than the plating process.

Near-threshold behavior of phase-locked devices, noting phase error processes
Systems analysis logic applied to mathematical modeling of dynamic nonlinear stochastic processes
Gimballed star trackers application to satellite attitude control for simplified signal processing
Isothermal hydrogen helium plasmas equilibrium radiation, discussing composition and radiation measurement, layers, line and continuum processes
Cometary encounter or large meteoritic impact leading to tektite formation process
Fabrication technique produces field aided lateral PNP transistors compatible with micropower switching circuits. The sub-collector diffusion is performed with phosphorus as the dopant and the epitaxy is grown using the higher temperature silicon tetrachloride process.
Printed matter as two dimensional, two valued, and stochastic process
Luminous spherical fog layer surrounding burning zirconium droplet during free fall through oxygen containing atmosphere, noting effect on mass and heat transfer processes
Cookie cutter device initiates production of identical, double-contoured fiber glass elements used as shock absorbers. Three-bladed edges convert triangular honeycomb elements into hexagonal shapes which are then stamped to desired length by concave and convex dies. Sandpaper smoothing completes the process.
Anodic bonding of glass coverslips to photodiodes and photovoltaic devices eliminates the need for adhesive. The process requires relatively low temperatures /less than 560 degrees C/ and the metals and glass remain solid throughout the bonding process.
