Patent number: 4175212Abstract: An inner conductor for a gas filled high voltage cable is constructed from plural elements arranged on a carrier tube in one or several layers. The conductive elements are either stranded around the carrier while remaining spaced from each other so that they can deform azimuthally in a wave-like pattern whenever their temperature increases, or alternatively, the conductor elements remain unstranded and are already contoured in a wave-like pattern whose amplitude excursion increases with temperature. In either case, length extensions of the elements are taken up by the wave pattern and do not cause overall length extensions of the conductor assembly as a whole.Type: GrantFiled: October 31, 1977Date of Patent: November 20, 1979Assignee: Kabel- und Metallwerke Guthehoffnungshutte AktiengesellschaftInventor: Jan Artbauer

Patent number: 4132854Abstract: A gas-insulated transmission line including an elongated outer sheath and a plurality of elongated inner conductors disposed within the outer sheath. An insulating gas electrically insulates the conductors from the sheath, and support means insulatably support the conductors within the sheath. The interior of the outer sheath is separated into a plurality of discrete compartments by walls, with each compartment having disposed therein one of the inner conductors. The compartmentalization of the outer sheath minimizes the possibility of a fault being transferred from one inner conductor to the other conductors.Type: GrantFiled: August 29, 1977Date of Patent: January 2, 1979Assignee: Westinghouse Electric Corp.Inventors: George A. Kemeny, Alan H. Cookson

Patent number: 4131759Abstract: A multiple caged armored electromechanical cable is provided which is characterized in being torque balanced and strength tapered throughout its entire length. The selective strength tapering of the cable permits the orientation of the cable such that the strongest portion thereof will support the entire cable and the weakest portion thereof will support only itself and whatever instrumentation is desirable. A slip sleeve mechanism is provided for retaining portions of the strength tapered elements of the cable to prevent inadvertant electrical shorting as well as providing for a relative slippage of the tapered strength elements with respect to select other elements of the cable.Type: GrantFiled: August 10, 1977Date of Patent: December 26, 1978Assignee: United States Steel CorporationInventor: Edward M. Felkel

Patent number: 4130722Abstract: A thick-film circuit module including a monolithic ceramic cross-over device, wherein the thick-film circuit includes a first conductive path and a second conductive path, transverse to the first conductive path and having spaced apart ends, and wherein the monolithic ceramic cross-over device is used in the second electrically conductive path as an electrically conductive device and for providing an insulative barrier between the first and second electrically conductive paths. The monolithic cross-over device comprises a ceramic chip including a plurality of stacked generally planar layers of ceramic material and electrically conductive metalized paths sandwiched between the respective layers of ceramic material, the ceramic chip having each of its opposite ends supporting an electrically conductive termination end cap, and the opposite ends of each of the electrically conductive metalized paths being connected to the respective termination end caps.Type: GrantFiled: January 10, 1977Date of Patent: December 19, 1978Assignee: Globe-Union Inc.Inventor: David H. Levijoki

Patent number: 4128736Abstract: While randomized splicing of twisted conductor pairs within groups in pulp cables is generally desirable to avoid electrical degradation resulting from systematic additions of capacitance unbalances, restoration of such cables, when severed, requires identification of each conductor pair for splicing. A cable design with a restoration color code has been developed which features groups having a manageable number of conductor pairs for identification splicing. Each group comprises several conductor pairs which have unique color combinations and which are precisely arranged in the group so the remaining conductor pairs having repeating color combinations can be identified by position relative to the uniquely colored pairs.Type: GrantFiled: March 30, 1977Date of Patent: December 5, 1978Assignee: Bell Telephone Laboratories, IncorporatedInventors: Wendell G. Nutt, Mark E. Roach

Patent number: 4125741Abstract: A compressed, multi-layered, concentric layer stranded cable electrical conductor with each succeeding overlying layer of strands helically wound in an alternately opposite direction, comprising the product of sequentially circumferentially compressing each succeeding overlying layer of cross lay strands to a regressively reduced state of consolidation.Type: GrantFiled: September 30, 1977Date of Patent: November 14, 1978Assignee: General Electric CompanyInventors: Ralph E. Wahl, Alfred C. Bruhin

Patent number: 4117260Abstract: Disclosed are several embodiments of Improved CATV (Coaxial Drop Wire), using either foil laminate or a metallic braid in combination with another foil laminate adhesively bonded to the drop wire core dielectric, the improvements being (a) the elimination of traverse (radial) cracks, commonly called "tiger striping," developing in the foil as a result of the foil wrinkling, and (b) the elimination of slot antenna effect. One embodiment employs two laminated tapes, one circumferentially surrounding the other and both circumferentially surrounding a core. One laminated tape is bonded to the core dielectric and the other is bonded to a jacket, surrounding the outer laminate tape. The other embodiment employs a metallic braid tape circumferentially surrounding a metal foil-plastic film-metal foil laminate tape adhesively bonded to the core dielectric.Type: GrantFiled: August 17, 1977Date of Patent: September 26, 1978Assignee: Comul Scope CompanyInventor: Frederic Nash Wilkenloh

Patent number: 4110554Abstract: A flexible, high load bearing, electrically conductive buoyant tether cable includes a center stress core having a plurality of jacketed stress bearing members which are in turn enclosed within a plastic-like core jacket. Seven conductor elements are cabled around the core, including three pairs of conductor elements and a jacketed coaxial cable. Each of the conductor element pairs includes a core, five twisted pairs of individually insulated, electrically conductive wires cabled around the conductor element core and a conductor tape binder surrounding the cabled pairs of wires. The conductor elements are cabled around the center stress core and are themselves enclosed by an outer tape binder and jacket. A plurality of intersticial stress members occupies a portion of the corresponding interstices between the cabled conductor elements and the outer tape binder.Type: GrantFiled: February 8, 1978Date of Patent: August 29, 1978Assignee: Custom Cable CompanyInventors: Boyd B. Moore, Clarence E. Kendall, Jr.
