20090283287 | DEVICE FOR PREVENTING ELECTRICALLY INDUCED FIRES IN GAS TUBING - The present invention provides a device for preventing electrically induced gas fires involving gas tubing such as Corrugated Stainless Steel Tubing (CSST) and gas appliance connectors (GAC). Connectors for coupling the gas tubing to gas lines and appliances are affixed at each end of the tubing. These connectors are made of a conductive material. Conductive wire (i.e. mesh surrounding the gas tubing) provides a direct electrical contact between the end connectors. If an electrical charge goes to ground via the gas tubing, such as from a lightning strike or an appliance short, the current is carried between the end connectors by the conductive wire instead of the gas tubing itself, thereby preventing damage to the gas tubing from the current. | 11-19-2009 |

The die and mandrel form a converging chamber leading to an extrusion orifice and the channel-forming member is positioned in the orifice. The mandrel has a central bore for supplying the conductor. Lubricated PTFE fine powder is forced through the chamber and out of the exit of the orifice as a lubricated green extrudate around the conductor forming an insulator with at least one closed longitudinal air channel spaced apart from the conductor. | 09-02-2010 |
20110132633 | PROTECTIVE JACKET IN A COAXIAL CABLE - A protective jacket in a coaxial cable. In one example embodiment, a coaxial cable includes two or more internal components and a jacket surrounding the internal components. The internal components include an electrical conductor configured to propagate a signal and an outer conductor surrounding the electrical conductor. The jacket includes two or more protruding portions and two or more recessed portions. Each recessed portion is positioned between two of the protruding portions. Each of the protruding portions makes contact with the outer conductor and each of the recessed portions does not make contact with the outer conductor. A method for manufacturing a coaxial cable with a protective jacket is also disclosed. | 06-09-2011 |
20110226503 | GAS INSULATED BUSBAR PARTICLE TRAP - A particle trap for a gas-insulated busbar (GIB) for high-voltage transmission systems. The particle trap is a circumferential cavity located and formed integral with a flanged end of the GIB's enclosure. In operation, particles present in a space between a central conductor and the enclosure of the GIB are guided to the particle trap by the presence of an electric field which exists between the central conductor and the grounded enclosure, and by the influences of gravity, mechanical vibration and gas flow. Once the particles enter the trap, the particles are immobilized. | 09-22-2011 |
20110253409 | COAXIAL CABLE CONNECTOR INSULATOR AND METHOD OF USE THEREOF - A coaxial cable connector having an insulator is provided, the connector insulator including a body having a circumferential surface and a central longitudinal axis, the body having a first axial end and a second axial end and having a first reentrant cavity extending from the first end toward the second end, wherein at least a portion of a wall surface of the first reentrant cavity is oblique to a central axis of the body. A corresponding method of insulating a coaxial cable connector is disclosed. | 10-20-2011 |
20160148714 | LOW OHMIC LOSS RADIAL SUPERLATTICE CONDUCTORS - Various examples are provided for low ohmic loss radial superlattice conductors. In one example, among others, a conductor includes a plurality of radially distributed layers that include a non-permalloy core, a permalloy layer disposed on and encircling the non-permalloy core, and a non-permalloy layer disposed on and encircling the permalloy layer. The non-permalloy core and non-permalloy layer can include the same or different materials such as, e.g., aluminum, copper, silver, and gold. In some implementations, the non-permalloy core includes a void containing air or a non-conductive material such as, e.g., a polymer. The permalloy layer can include materials such as, e.g., NiFe, FeCo, NiFeCo, or NiFeMo. In another example, a via connector includes the plurality of radially distributed layers including the permalloy layer and the non-permalloy layer disposed on and encircling the permalloy layer. The via connector can extend through glass, silicon, organic, or other types of substrates. | 05-26-2016 |
