Patent number: 4581275Abstract: The present invention provides a base cloth for reinforcement produced by winding a weldable yarn on either one of a warp or weft or the both at a definite interval, arranging the warp and weft in the respective directions and then thermally welding the both yarns.

Patent number: 4568415Abstract: In the method for manufacturing strings, a plurality of narrow strip layers (22) of synthetic material are successively and coaxially helically wound on the cylindrical surface of a continuous core. The winding (3) thus produced is conveyed hot to a welding area (7) wherein the narrow strips (22) of synthetic material are mutually assembled by welding.

Patent number: 4460419Abstract: An optical fiber submarine cable is made by extruding a metallic pressure tube by a friction extrusion technique, compressing the tube, applying tensile strength members, applying a conductive tape over the strength members and extruding plastic dielectric material over the tape. Armoring can subsequently be applied for shallow water application.Type: GrantFiled: August 11, 1983Date of Patent: July 17, 1984Assignee: International Standard Electric CorporationInventors: Colin S. Parfree, Peter Worthington

Patent number: 4455348Abstract: An insulative coating composition for providing water-repellancy to and protecting communication wire comprises an admixture of an anhydride copolymer, a flexibilizing copolymer, a suitable solvent system, a hydrophobic, soluble, compatible fluoroaliphatic radical-containing composition and optionally, a mercaptan, and optionally, an antioxidant. Articles coated with the insulative composition are disclosed.Type: GrantFiled: July 27, 1983Date of Patent: June 19, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventor: Richard J. Pokorny

Patent number: 4449014Abstract: Plastic/metal laminates (such as, for example, plastic coated cable shielding or armoring tapes) having improved high and/or low temperature adhesion to various olefin polymer substrates (such as, for example, cable jacketing resins) are provided which comprise at least one metallic substrate having directly adhered to at least one surface thereof a first thermoplastic polymer layer of a random copolymer of ethylene with an ethylenically unsaturated carboxylic acid monomer and having adhered to said first polymer layer a second thermoplastic polymer layer comprising a polymer blend of (a) either the same or a different random copolymer of ethylene with an ethylenically unsaturated carboxylic acid as used in said first polymer layer and (b) at least one different ethylenic olefin polymer resin which is not a random ethylene/unsaturated carboxylic acid copolymer.Type: GrantFiled: August 9, 1982Date of Patent: May 15, 1984Assignee: The Dow Chemical CompanyInventor: Richard H. Brezinsky

Patent number: 4443277Abstract: Telecommunications cable formed by locating a plurality of conductors in a group in an open array, which is preferably planar, and shaping the group into arcuate configuration around a longitudinal axis with the conductors extending generally in the direction of the axis. A layer of insulation is then provided around the group to hold it in its planar configuration.Type: GrantFiled: September 23, 1982Date of Patent: April 17, 1984Assignee: Northern Telecom LimitedInventor: Bernard E. Rokas

Patent number: 4442138Abstract: A method of curing an anaerobic resin, which primarily contains acrylic resin, includes externally catalyzing the cure of the resin with a metal-beta keto ester complex having the structural formula: ##STR1## where M is a transition metal; R.sub.1 is selected from the group consisting of alkyl groups having from 1 to 20 carbon atoms, benzene, naphthalene, anthracene, and hydrocarbon substituted aromatic; R.sub.2 and R.sub.3 are selected from hydrogen, alkyl groups having from 1 to 20 carbon atoms, benzene, naphthalene, anthracene and hydrocarbon substituted aromatic; R.sub.4 is selected from alkyl groups having from 1 to 20 carbon atoms; and n is equal to the valence of the metal M.Type: GrantFiled: February 22, 1982Date of Patent: April 10, 1984Assignee: Westinghouse Electric Corp.Inventors: George J. Bich, Thomas M. Burke, James D. B. Smith
