Patent number: 6147309Abstract: A communications cable having superior electrical characteristics and meeting the burn requirements for plenum applications has a core formed of one or more twisted wire pairs having primary insulation formed of a suitable material, such as high density polyethylene. The core is surrounded by a single outer jacket formed from a material having excellent heat/flame resistance characteristics and acceptable electrical characteristics that are substantially stable at relatively high temperatures, such as a foamed thermoplastic halogenated polymer, for example polyvinylidene fluoride material. The electrical conductors utilized by the cable are oversized (relative to conventional 24 gauge conductors) to enhance the electrical performance of the cable. An air gap formed between the conductor core and the outer jacket further enhances the electrical performance of the cable.Type: GrantFiled: October 25, 1999Date of Patent: November 14, 2000Inventors: John J. Mottine, Kenneth S. Koehler, Sayed J. Mirkazemi, William B. Dawson

Patent number: 5326638Abstract: A cable (20) which may be used for communications, for example, include transmission media (24-24), each having a plastic composition of matter disposed thereabout. The insulation (26) comprises a polyvinyl chloride composition which includes a lubricant and a lead-free stabilization system. The stabilization system includes a calcium-zinc constituent in combination with an antioxidant-metal deactivator complex which provides a sacrificial function to prevent the formation of calcium or zinc chloride which would affect adversely the electrical properties of the insulated conductor. A jacket (28) typically is disposed about a plurality of the transmission media and comprises a non-lead stabilized plastic composition of matter.Type: GrantFiled: August 29, 1991Date of Patent: July 5, 1994Assignee: AT&T Bell LaboratoriesInventors: John J.

Patent number: 5087521Abstract: It has been found that the properties of poly(vinyl chloride) based polymers are substantially enhanced through the use of a specific plasticizer system. In particular, the use of specific triarylphosphates in combination with specific diarylphosphates in specific proportions not only plasticizes the PVC polymer but produces a transparent, flame retardant heat resistant, easily worked polymer. These materials are used so that the diarylphosphate is 30-45% of the total concentration of the phosphates and such that 45 to 70 parts of the phosphates are present per 100 parts of the polymer.Type: GrantFiled: October 2, 1986Date of Patent: February 11, 1992Assignee: AT&T Bell LaboratoriesInventors: Jae H. Choi, John J. Mottine, Walter J. Sparzak, Sr., Walter D. Tates, William C. Vesperman

Patent number: 5074640Abstract: A cable which may be used in buildings in concealed areas such as in plenums or in riser shafts includes a core (22) which includes at least one transmission medium each of which is enclosed with a non-halogenated plastic composition of matter. The core is enclosed with a jacket (28) which also is made of a non-halogenated plastic composition. The non-halogenated plastic material of the insulation includes a polyetherimide constituent and an additive system. The additive system includes an antioxidant/thermal stabilizer and a synergistic metal deactivator and may include a lubricant. For the jacket, the plastic material is a composition which may include a siloxane/polyimide copolymer constituent blended with a polyetherimide constituent and an additive system to improve processing and long term aging, or a siloxane/polyimide copolymer constituent with a flame retardant system.Type: GrantFiled: December 14, 1990Date of Patent: December 24, 1991Assignee: AT&T Bell LaboratoriesInventors: Tommy G.

Patent number: 5045249Abstract: Electrical interconnections are made by means of a layer or sheet medium comprising chains of magnetically aligned, electrically conducting particles in a nonconducting matrix material. End particles of chains protrude from a surface of the medium, thereby enhancing electrical contact properties of the medium. The medium can be used for temporary as well as permanent connections; in the latter case the use of a nonconductive adhesive material is convenient for physical attachment to contacts on both sides of the medium.Type: GrantFiled: February 9, 1988Date of Patent: September 3, 1991Assignee: AT&T Bell LaboratoriesInventors: Sungho Jin, John J. Mottine, Jr., Robert L. Opila, Jr., Richard C. Sherwood, Thomas H. Tiefel, William C. Vesperman

Patent number: 4923739Abstract: An electrical interconnection medium is made as a composite of electrically conducting, magnetic particles in a nonconductive matrix material. Particles are magnetically aligned into a network which extends in at least two dimensions as, e.g., in a sheet or layer medium. A layer medium may further include additional, larger conductive particles which may be magnetically aligned into columns extending the thickness of the medium; typically, in this case, the medium serves as an anisotropically conductive medium in the direction of the columns, with slight in-plane conductivity imparted by the network aiding the dissipation of electrostatic charge.Type: GrantFiled: July 30, 1987Date of Patent: May 8, 1990Assignee: American Telephone and Telegraph CompanyInventors: Sungho Jin, William R. Lambert, Robert C. Moore, John J. Mottine, Jr., Richard C. Sherwood, Thomas H. Tiefel

Patent number: 4737112Abstract: Electrical interconnection is established by means of an anisotropically conductive, composite layer medium comprising electrically conductive particles in a nonconductive matrix material. Enhanced uniformity of conductivity across the medium, and minimized incidence of lateral shorting are achieved as a result of essentially uniform distribution of electrically conductive particles which are also magnetic, such distribution resulting upon application of a magnetic field essentially perpendicular to a layer before or during hardening of the matrix material.Type: GrantFiled: September 5, 1986Date of Patent: April 12, 1988Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: Sungho Jin, John J. Mottine, Jr., Stephen G. Seger, Jr., Richard C. Sherwood, Thomas H. Tiefel

Patent number: 4644101Abstract: Electrical signals are produced by a pressure-responsive device, such signals being indicative of the position of locally applied pressure. The device comprises a position sensor assembly which comprises a composite layer medium including electrically conductive magnetic particles in a nonconductive matrix material. The particles are aligned into chains extending across the thickness of the layer, and chains include a non-conductive gap which is bridged upon application of sufficient pressure. The medium is sandwiched between sheet electrodes, and the resulting assembly may be transparent as is advantageous in writing pad and touch-sensitive screen applications. The pressure-responsive device is suitable, e.g., as an input device in graphics information systems, in combination with transmission and display facilities.Type: GrantFiled: December 11, 1985Date of Patent: February 17, 1987Assignee: AT&T Bell LaboratoriesInventors: Sungho Jin, John J.

Patent number: 4584241Abstract: The epoxy resin stabilizing systems in combination with cadmium containing stabilizers employed in PVC compounds are replaceable without affecting other properties of the polymer by utilizing a specific additive mixture. In particular, a complex ester of oleic acid and a diglycerol ester of oleic acid are employed in conjunction with a calcium-zinc composition. The resulting system yields excellent processing and long-term stability without significantly affecting other properties such as color stability and flame retardancy.Type: GrantFiled: April 6, 1984Date of Patent: April 22, 1986Assignees: AT&T Technologies, AT&T Bell LaboratoriesInventors: Jae H.

Patent number: 4339298Abstract: An extrusion system for covering a flexible conductor (14) with a crystalline thermoplastic elastomer insulating material by tubing the plastic onto the conductor includes a core tube (61) which is mounted in an extruder crosshead (41) such that its free end is positioned within the interior of the extruder die (59). The free end of the core tube is spaced from the die opening a predetermined percentage of the land length of the die. In this arrangement, which has been found to be suitable for a crystalline thermoplastic elastomer having a crystallization initiation temperature which is capable of being substantially near to its melting point temperature, the crosshead and the core tube are arranged to provide a streamlined flow path of the insulating material toward the die opening.Type: GrantFiled: January 29, 1981Date of Patent: July 13, 1982Assignee: Western Electric Company, Inc.Inventors: William M.
