A two stage threshold detector in which the first stage is used for buffering and stabilization and the second stage constitutes a current mode switch. The first stage - second stage interface is a network having a configuration and component value selected to optimize the speed of response of the current mode switch to input voltage transitions through the threshold level. The input circuit of the current mode switch is clamped at the upper and lower limits of a preselected linear voltage range...

Continuous filaments are subjected to treatments to produce in the axial ection of each filament alternating and repeating high shrinkage segments and low shrinkage segments. Yarns and fabrics produced from the filaments will bulk out in the low shrinkage segments by the shrinkage of the high shrinkage segments upon being subjected to a relaxation treatment.

A high voltage switch for closing on high current flow has a pair of arcing contacts spaced apart at the distal end of a switch blade for engaging therebetween a graphite arcing tip prior to engagement by the switch blade of a stationary metallic contact.

Method for obtaining a recrystallized austenite structure in steel by carrying out more than one severe reduction per pass between 1,100.degree.C and 950.degree.C in the hot rolling process of a steel comprising 0.005 - 0.15% C, less than 0.6% Si, 0.70 - 2.0% Mn and 0.01 - 0.15% Nb and containing other effective elements if necessary, with the remainder being essentially Fe, and then rolling the steel to obtain a high toughness, high tension steel plates and strips.

The invention is directed to the construction of a roller used to convey hot glass sheets and includes the application of a seamless compressible fabric sleeve of silica fibers covering a rigid refractory cylindrical core.

In a circulator using strip technology a high thermal conductivity through the piled up parts is obtained by use of heat conductive insulating grease layers between the parts which include a solid machined metal cap surrounding the gyromagnetic pellets and broad banding circuits between the ports and earthed contacts on the strip substrate, the capacitor of which uses said cap as an electrode. The outside of said cap is cylindrical, the inside hexagonal.

An apparatus for developing high temperature and high pressure has a pair of identical dies having opposing cooperating end faces, each face end having therein a spherical cavity and a conically tapering peripheral portion. When the end faces of the two dies are brought closer together, the two spherical cavities conjointly form therebetween a high pressure chamber in which there is received a container made of a plastic material, and the respective peripheral tapering portions form therebetween...

High-power, high-frequency, radio impulses are derived from the energy stored in a low-impedance, resonant transmission line. The energy is discharged by a suitable switching device, generally a spark gap, and the resulting R.F. oscillations are coupled to an antenna. BACKGROUND OF THE INVENTION This invention relates to a method and means of generating high-power, short-duration, radio-frequency signals. Switching techniques are used to effect the short-pulse, high-power signal generation. Abou...

This improved analog sample and hold circuit corrects for amplifier offset voltage and is readily adaptable to monolithic mechanization using complementary MOS techniques. Offset correction is accomplished by using a high gain differential input amplifier twice but through opposite input terminals. The amplifier offset voltage thus also occurs twice, but with opposite polarity hence eliminating itself.

A rapid-action switch, especially for the switching of high voltages and rents in plasma physics, magnetohydrodynamics and like technologies in which an explosive force is produced by discharge through a consumable electrode within a U-shaped aluminum body separated from a switching electrode bearing a sharp edge and sandwiched between this electrode and a counterelectrode constituting an anvil. An insulating layer between the proximal leg of the aluminum U and the sharp edge is pierced as this ...
