Abstract: A used needle is inserted in a housing of a needle apparatus disabling device. As the needle is pushed downwards sealing a collar opening and bears against a stationary cutter blade. The needle is pushed further into the device where it contacts upper and lower electrodes. An electric current passes through the needle, which causes it to become heated resistively to destruction. A voltage drop between the electrodes is detected by a processor activating a motor driven movable cutter blade which then severs a remaining stub or remnant of the needle portion and simultaneously urges the severed stub downwardly onto the electrodes to ensure its complete destruction. During this process any sparks or airborne contaminants, or combustion gases are prevented from escaping through the opening by the sealing action of the apparatus.

Abstract: The invention is a method to regulate gas pressure by controlling the expansion of a gas through an air motor that is attached to an electric generator. There are four components. The first is a sensor that measures the pressure of the gas coming into the air motor. The second is an air motor that changes the pressure of the gas into mechanical energy. The third is a generator that takes the mechanical energy from the air motor and changes it into the electrical energy. The forth is a control unite. The control unit reads the pressure of the gas from the sensor and varies the electric load on the generator. The varying of the electrical load on the generator varies the torque on the air motor which changes the pressure of the gas passing through the air motor.

Abstract: A device used to disable hypodermic needles uses a power supply (10) and two electrodes (12,14) in a housing. One electrode is placed over the other electrode and slants down towards the other. A collar is used to ensure that when the hypodermic needle is inserted in the device, it will hit the electrodes at the proper point. When the hypodermic needle contacts both electrodes, electricity will flow from the power supply through the lower electrode and up the needle to the top electrode. The electrical resistance of the needle is very high so that it quickly heats up to cause disintegration of the needle.

Abstract: A bismuth-strontium calcium cuprate material shows commercial promise as a high-T.sub.c superconductor material, means are desired for producing such (as well as isostructural) superconductor material in the form of macroscopic single-crystal bodies. The invention provides for the growth of such bodies from a fluxed melt, in bulk or epitaxially on a substrate, the fluxing agent being chosen to include sodium chloride, potassium chloride, or a mixture of sodium chloride and potassium chloride.

Abstract: This invention is a technique for forming a specifically configured region of material which is rejected by an advancing freezing front within a melt. Resolidification of the molten material is effected in such a manner that liquid-solid interfaces intersect so as to control the shape and location of the rejected material which solidifies. Specific embodiments involve the formation of wires, tubes, or planes of enriched rejected material. Applications include the formation of enriched conductive material for making electrical contact between internal or external regions of electronic devices. Additionally, enriched material with etching properties different than that of the surrounding material may be formed and subsequently etched away in micro-machining applications.

Abstract: A temperature gradient zone melting process is disclosed wherein the temperature gradient is established substantially across only the molten zone by preferentially heating the molten zone. In a specific embodiment, the mechanism for inputting heat to the molten zone involves exposing the substrate to optical radiation of a wavelength and magnitude for which the molten zone is absorptive and the remainder of the body is transparent. The molten zone thereby migrates through the body toward the source of optical radiation.
