摘要： First and second spaced members are hermetically sealed by a partially amorphous and partially crystalline insulating material. The insulating material is non-hygroscopic and is able to withstand forces of about 26,000 psi at about 700.degree. F. It may provide resistances of at least 10,000 megohms even when subjected to 500 volts AC or DC and to steam at about 212.degree. F. for three (3) days. A second insulating layer may be fused to the first insulating layer with essentially the same properties and composition as the first layer. However, the second layer may be more crystalline than the first layer to provide a mechanical and chemical barrier. The insulating materials may be formed from the oxides of lead, zinc, aluminum, silicon, cerium, lanthanum, cobalt, sodium, zirconium, bismuth and molybdenum. The oxides of lead, silicon, bismuth and sodium may be glass formers. The oxides of cerium, lanthanum and zirconium may form crystals. A mixture of the oxides may be heated to at least 2000.degree. F. for several hours and quenched in water to form first beads. These beads may be disposed between the first and second members. The assembly may then be heated for a limited time at about 1900.degree. F. and then quenched. The second insulating material may be formed into beads as described above. These beads may be disposed to abut the first beads. The insulating materials may then be fused by heating them to the elevated temperature for the limited time as discussed above.

摘要： This high-voltage terminal bushing comprises a tubular shell of electrical insulating material having a passageway extending between its ends and an electrical conductor within the passageway that has an external surface spaced from the internal surface of the passageway. The external surface of the conductor is covered with a thin coating of insulating material spaced from the internal surface of the passageway by a cylindrical air gap. The coating has sufficient dielectric strength to prevent any corona streamers from the conductor from impinging against said internal surface at impulse voltages up to the rated impulse insulation level of the bushing.

摘要： A cable socket adapted to be mounted in an opening formed in a housing wall for providing traction relief for a cable passing therethrough includes a tubular grommet insertable in the housing wall opening and an inner socket portion coaxially situated within the tubular grommet so as to be twistable therein around the common axis, the inner portion having a passage opening for receiving a cable and including a flexible extension for encompassing a cable passing through the passage opening, the flexible extension having a free end region, and a device for securing the free end region of the flexible extension of the inner socket portion to the tubular grommet so that it is prevented from twisting with respect to the grommet when the inner socket portion is twisted within the grommet. In operation, upon twisting the inner portion with respect to the grommet with a cable received in the passage opening and the free end region of the flexible extension secured to the grommet so as to be prevented from twisting with respect thereto, the flexible extension is twisted to compress against the cable to hold the same in the socket and provide tension relief therefor.

摘要： A ferrule is provided with an opening extending through the ferrule and a terminal pin is disposed in the opening in spaced relationship to the ferrule. A plurality of insulating members are disposed on the terminal pin in the opening in a stacked relationship. Each of the insulating members is fused to the terminal pin and the ferrule. Each of the insulating members in the stack has a higher temperature of fusion than the preceding members in the stack. The insulating members in the stack are progressively fused to the ferrule and the terminal pin by the application of progressive temperatures to the terminal pin, the ferrule and the insulating members.The insulating members having the highest temperature of fusion are provided with properties of being able to withstand large forces without any degradation of the fusion with the terminal pin and the ferrule. The insulating members of the reduced temperatures of fusion are able to withstand other types of shock such as sudden changes in temperature.The terminal pin extends through the ferrule to a position external to the ferrule. An additional insulating member is disposed on the ferrule in hermetically sealed relationship with the terminal pin and the ferrule at the external position.

摘要： Acid and alkali oxides are smelted for an extended period of time at a first elevated temperature above their melting temperatures. The smelted mixture is then quenched in water and fritted. The fritted mixture is then disposed between a pair of members which are to be hermetically sealed relative to each other. The fritted mixture is then at least partially fused in an oxygen atmosphere at a second temperature below the first temperature for a relatively short period of time. The at least partially fused mixture is then rapidly cooled in air. In this way, the mixture is provided with a partially amorphous state and a partially crystalline state. The crystals in the mixture are disposed primarily at the borders of at least a particular one of the members to be sealed.The mixture hermetically seals the two members, is resistant to acids and alkalis and inhibits the propagation of cracks. The mixture is particularly adapted to seal steels such as stainless steels and steel alloys including cobalt and molybdenum or including nickel and chromium. The mixture is also adapted to seal noble metals such as platinum and also alloys such as those including nickel.

摘要： A high voltage seismic bushing charged with an insulating material has a procelain tube having an adapter rigidly connected to one end of the tube. The adapter is flexibly connected to a mounting flange such that the porcelain tube is free to move relative to the mounting flange in the event of an earthquake. The means for flexibly connecting the adapter to the mounting flange utilizes a spring mechanism to absorb the energy through friction to attenuate the movement of the porcelain tube. A resilient buffer member is interposed between the adapter and the mounting flange to provide a predetermined spacing therebetween and absorb the impact due to the movement of the adapter relative to the mounting flange. A sealing member seals the interface between the adapter and the mounting flange for containing the insulating material charged therein.

摘要： The strain relief grommet has internally located intermittent clamping teeth and when the grommet is located around a cord set and then lodged in a notch in a frame of a motor, teeth pierce the outer jacket of the cord and engage the internal insulation wrappings around the lead wires. This prevents removal or loosening of the cord from its internal connection in the event the cord set is pulled from outside of the motor.

摘要： An electrical bushing which contains a pressurized gas as the main insulation and which contains a metallic shield electrode therein near the grounded end of the tubular outer insulator for control of the voltage distribution, also includes a solid insulating body which is made of a material having a higher permittivity than the insulating gas, thus enabling the bushing to have a smaller diameter. The metallic shield electrode is at least partially embedded in the insulating body. The insulating body includes an upper field-controlling portion in the space between the tubular outer insulator and the central current conductor which includes an inner side that extends towards the conductor to form a tapered annular space, most of the upper portion being located beyond the metallic shield electrode with respect to the grounded end of the tubular insulator.
