Abstract: A liquid barrier contact to InP made of 40% tartatic acid and 30% hydrogen peroxide in a 3:1 ratio by volume is used for capacitance-voltage carrier profiling to large voltages (>10 V) on relatively heavily doped material (>10.sup.17 CM.sup.-3) and at room temperature.

Abstract: A coaxial strain cable tows a tube-like net-containing pod behind a ship. nsors on the pod carried beneath the ships wake detect incoming torpedoes and supply detection data via the coaxial cable to a shipboard processor. Processor commands return via the cable to a pod motor to drive rudders and maneuver the pod into the torpedo path. Drogue and main parachutes packed in the pod are released into the path by other cable-carried commands. Power for the motors and a 'chute release mechanism also is supplied through the cable. The main 'chute is formed of a low drag aramid fiber mesh strong enough to arrest the torpedo. Preferably, explosives carried by the 'chute destroy it.

Abstract: A coded signal is added in the transmitting channel of a communications sem to provide, at the receiver site, an adaptive processor with a reference signal for adaption. At the receiver site, the reference signal is removed to provide an error signal which is fed to the adaptive array processor. The error signal is also fed directly to the communications receiver without further processing.

Abstract: A donor gas, such as helium or argon, is pumped into a receiving end of a chamber formed with widely-diverging walls providing an expanded area at its delivery end. Electrodes mounted in the receiving end produce a potential capable of exciting the admitted gas into He.sub.2.sup.+ or argon metastables. An arc discharge is produced for the helium and a glow discharge for the argon. The excited donor then flows through the chamber to a diffusion mixer formed by an array of nozzles covering its expanded delivery end area where it continually mixes with an acceptor gas, such as N.sub.2, supplied through the nozzles. Mixing results in an electronic excitation energy transfer reaction in which the charge from the excited donor is transferred to the acceptor. An optical resonant cavity communicating with the nozzle array receives the excited acceptor and population inversion in the cavity generates a laser beam. With nitrogen, the emission is a continuous wave in the UV-visible region.

Abstract: Conventional heat pipe performance can be improved by reducing the dependency upon the capillary pumping limitation. Electrodes mounted either in the working fluid vapor or its condensate produce an ion flow directed axially and in the same flow direction. The ion flow, through collision phenomena, picks-up the surrounding low velocity stream, increases its momentum and generates additional pumping pressure for the condensate. Performance can be improved even when low surface tension working fluids are used.

Abstract: The destructive fragments used in the warhead are in a form of rods of suantially the same length as the warhead itself. Effectiveness is increased by so controlling the outward travel of the rods as to produce a propellering motion about the center of the rods capable of causing the rods to line-up end-to-end at a particular desired radius. The long rods are disposed longitudinally side-by-side in a circular path to form a continuous sleeve about a cylindrical explosive charge. Each rod also is inclined at a slight angle from the longitudinal axis of the warhead to induce the desired propellering motion. The velocity of the warhead is made uniform throughout the length of each rod to minimize tumbling.

Abstract: An array of oceanographic instruments is supported on a tension line exteng horizontally at a selected ocean depth between a pair of vertical lines one of which is a ship-borne, end-weighted, winched cable and the other a float-supported and anchored guide line. To hold the array at a selected level, a buoyant package is moved along the guide line to a selected location where it grips the line and exerts its positive buoyant force. By matching positive buoyancy of the package to the negative buoyancy of the weighted cable, opposing, tension-producing forces are applied to the tension line to hold it in its horizontal disposition. The motive power for the buoyant package is supplied by the ship through its cable and the coupled tension line. The horizontal disposition of the array initially is achieved by moving both the cable and the buoyant package to the selected level.
