摘要： An electrochemical corrosion potential sensor is fabricated by initially joining an electrical conductor to a sensor tip. An electrical cable is joined to the tip conductor. Ceramic powder is fused under heat around the tip conductor to form an integral annular electrically insulating band therearound to insulate the tip from the cable. The band may be formed by plasma spraying, or it may be molded and sintered to seal it to the tip and conductor without brazing. In a preferred embodiment, the band is formed of yttria-stabilized-zirconia or magnesia-stabilized-zirconia.

摘要： A ceramic sensor is disclosed that includes a ceramic tube having a closed end and an open end, and a metal sleeve having open first and second ends. The ceramic tube is formed of stabilized zirconia. The metal sleeve extends about the open end of the ceramic tube and is sealingly joined thereto at a contact region by a brazeless bond resulting from hot isostatic pressing. A mixture of metal and metal oxide powders is provided within the ceramic tube adjacent the closed end, and a conducting wire extends from the mixture of metal and metal oxide powders to the second end of the metal sleeve.

摘要： A self-sharpening refractory metal cutting tool presenting an overhanging cutting portion, i.e. a flange, or ledge, of width equal to (or slightly greater than) the depth of the cut to be taken and maximum thickness equal to tolerable tool flank wear is disclosed. This tool construction has special utility in a novel high-speed cutting method in which only the tool flange does the cutting in which operation the flange is worn away with the wear progressing lengthwise of the flange during which time the flange sequentially performs a roughing cut and then a finishing cut in a single pass.

摘要： A mass of diamond crystals contacting a mass of elemental silicon are confined within a pressure-transmitting medium. The resulting charge assembly is subjected to a pressure of at least 25 kilobars causing application of isostatic pressure to the contacting masses which dimensionally stabilizes them and increases the density of the mass of diamond crystals. The resulting pressure-maintained charge assembly is heated to a temperature sufficient to melt the silicon and at which no significant graphitization of the diamond occurs whereby the silicon is infiltrated through the interstices between the diamond crystals producing, upon cooling, an adherently bonded integral body.

摘要： A current limiter device comprises at least two electrodes; an interlocked-array electrically conductive composite material disposed between the electrodes; interfaces disposed between the electrodes; an inhomogeneous distribution of resistance at the interfaces whereby, during a high current event, adiabatic resistive heating at the interfaces causes rapid thermal expansion and vaporization and physical separation at the interfaces; and means for exerting compressive pressure on the electrically conducting composite material. The interlocked-array electrically conductive composite material comprises an interlocked-array of spaced apart discrete regions of at least one insulating flexible material and at least one electrically conductive composite material. A method for forming the interlocked-array electrically conductive composite material structure is also set forth by the invention.

摘要： A current limiting system for a circuit limits current flow through the system. The current limiting system comprises at least one main switch comprising first and second main switch contacts and a contactor connecting the first and second main switch contacts; at least one current limiting device and at least one solid-state switch, which are mechanically unconnected to the main switch, and the at least one current limiting device and least one solid-state switch are arranged in series on a series side of the circuit; the at least one main switch is on a main switch side of the circuit arranged in parallel with the series side; a control that senses a predetermined condition of the circuit, and operably connected with the at least one solid state switch to open and it. Under normal operating conditions, most current flows through the at least one main switch side. When the predetermined condition causes the main switch to open, and the resistance increases in a main switch side. Thus, current flows to the series side of the circuit side. The current limiting device then switches its state from a low resistance to a high resistance state to limit the current passing through the current limiting system, where the control has sensed a predetermined condition and signals the solid-state switch to open, thereby interrupting current flow through of the current limiting system.
