Generator produces dynamic test signals in the range from 0.0001 and 10 to the minus 12th power amperes. It involves an extension of the technique of applying a triangular voltage waveform to a small capacitor to obtain a square-wave output current. The effects of stray capacitance are minimized by appropriate shielding.
Metal flame spray coating prevents EMF measurement error in sheathed instrumentation cables which are externally attached to cylinders which were cooled on the inside, but exposed to gamma radiation on the outside. The coating provides a thermoconductive path for radiation induced high temperatures within the cables.
Measurement of torques generated by interaction between magnetic dipole of spacecraft and ambient magnetic field
Brownian motion under micrometeorite impact effects on accuracy of spacecraft measurements of Einstein light bending
Ultrahigh vacuum technology including cryopump, getter ion pump, diffusion pump, and pressure standardization studies
Life testing of angular contact steel ball bearings with hydrocarbon lubricant at high temperatures, speeds, and loads
Planform design method, general characteristics, and aeroelastic stability of flexible lifting rotors
Inflatable tourniquet effects on cardiovascular deconditioning during bed rest and water immersion studies on humans
Wind tunnel wall effects for highly deflected wakes
Design of spectroheliograph to detect solar corona
Shock tube technique for producing subsonic, transonic and supersonic flows with high Reynolds numbers
Minimality of singular arcs over short intervals of time, discussing interrelationships between second variation test and transformation approach to subarcs
Curie point writing on MnBi thin films using pulsed high intensity ruby laser, flash lamp, focusing cavity and pinhole aperture
Method accurately measures the flow of gases produced by evaporation or sublimation at pressures approaching total vacuum. Measurement of heat rejection in terms of flow of steam is taken with water as the liquid undergoing change in phase.
Ball bearing endurance tests and lubricant film thickness measurements under conditions of high temperature, pressure, and speed
