Steady-state and dynamic characteristics of full circular bearing and centrally loaded arc bearing presented in design charts for turbulent lubrication analysis
Electron beams from duoplasmatron using hollow cathode arc, noting current density distributions
Laboratory arc furnace using rapidly interchangeable hearths gains considerable versatility in casting so that buttons or special shaped castings can be produced. It features a sight glass for observation.
Water cooling system increases the life of the anode of a high temperature compact arc lamp. A shaped water passage is provided through the tip or hottest point of the anode so that water will flow through it at a relatively high velocity.
Portable weld tool makes weld repairs out-of-station and on the side opposite the original weld. It provides full automatic control of the arc voltage, current, wire feed, and electrode travel speed in all welding attitudes. The device is readily adaptable to commercially available straight polarity dc weld packs.
Coating the electrode-insulator contact area with silver epoxy conductive paint and forcing the electrode and insulator tightly together into a permanent connection, eliminates electrical arcing in high-voltage electrodes supplying electrical power to vacuum facilities.
Error analysis for selecting optimum rates for taking counted doppler rate and range data for tracking short arc of lunar satellite orbit
Multiple exposure to vibration and functional state of spinal reflex arc in guinea pigs
Numerical determination of energy and mass transport characteristics of gas flowing axially through constricted arc plasma generator
Computation of arcs for optimal flight paths with state variable inequality constraints
Fluid transpiration arc radiation source for solar simulation
Composite metallic and dielectric insulators for high current arc electrodes
Oblique shock detection in conical nozzle with circular arc throat, noting measurement techniques
Stallwood jet and DC arc in analysis of air contamination in inert gases
Electrode geometry effect on current and potential distributions in MPD arcs
Propellant injection through electrodes effect on potential distribution in MPD arc
Low power MPD arc thrustor design and performance with radiation cooled electromagnets and permanent magnets
