This web is metallized with a low emissivity metal(s) and/or alloy(s) to produce a coated web wherein at least 50 percent of the surface area of the web fibers are coated with metal and or alloy. The coated web is shredded into individual, staple fibers which are thereafter united to produce a nonwoven, lofty three-dimensional insulating web having a density of between about 0.02 to 2 pounds per cubic foot.Type: GrantFiled: March 26, 1990Date of Patent: November 19, 1991Assignee: Ultrafibre, Inc.Inventor: William Huykman

Patent number: 5061554Abstract: A tape-formed or sheet-formed insulating material for use in windings and coils of electrical machines includes an insulating layer in the form of a homogeneous film of an organic polymer or in the form of a felt of a paper of fibres of an organic polymer and a protective layer coated on at least one side of the insulating layer which protects the insulating layer against degradation caused by corona. The protective layer comprises an organic polymer containing at least 10 percent by volume of a powdered filler in the form of chromium oxide, iron oxide or a mixture of chromium oxide and iron oxide. The filler preferably has an intrinsic resistivity of 10.sup.4 -10.sup.8 ohm m. The thickness of the protective layer and the total thickness of the protective layer, respectively, are preferably smaller than the thickness of the insulating layer and the resistivity of the protective layer is preferably in excess of 10.sup.10 ohm m.Type: GrantFiled: March 21, 1988Date of Patent: October 29, 1991Assignee: Asea Brown Boveri ABInventors: Arne Hjortsberg, Goran Holmstrom, Lennart Johansson, Thommy Karlsson

Patent number: 5057367Abstract: A flame retardant comprising a mixture of 10 to 90% by weight of powder A and 90 to 10% by weight of powder B of magnesium hydroxide, the powder A containing 40 to 70% by weight of a powdered double salt of magnesium carbonate and calcium carbonate and 60 to 30% by weight of powdered basic magnesium carbonate; and a flame-retardant resin composition comprising 100 parts by weight of a thermoplastic resin and 30 to 300 parts by weight of the flame retardant. Preferably, the double salt is huntite, and the basic magnesium carbonate consists essentially of hydromagnesite. It is preferred to treat the flame retardant, in the form of a powder mixture, with a surface treatment agent. The flame-retardant resin composition is adapted for use as a sheath or insulation for an electric wire or cable, a fire-arresting material, or a wall material.Type: GrantFiled: February 5, 1990Date of Patent: October 15, 1991Assignees: The Furukawa Electric Co., Ltd., Ube Chemical Industries, Co., Ltd.Inventors: Akira Morii, Shunichi Fujimura, Kiyoshi Nakayama

Patent number: 5049684Abstract: An electrically conducting material including a cyanic group-containing material having adsorbed thereby copper sulfide. The cyanic group-containing material is in the form of powder or shaped body such as fiber, film, plate, rod or like and is formed of a synthetic polymer such as polyacrylonitrile or a polyamide having introduced thereinto cyanic groups; a naturally occurring polymeric substance such as cotton having introduced thereinto cyanic groups; or a low molecular compound such as phthalonitrile. The electrically conducting material may be prepared by treating the cyanic group-containing material with a source of monovalent copper ions and a sulfur-containing compound to form copper sulfide adsorbed by the cyanic group-containing material.Type: GrantFiled: September 3, 1982Date of Patent: September 17, 1991Assignee: Nihon Sanmo Dyeing Co., Ltd.Inventors: Shinji Tomibe, Reizo Gomibuchi, Kiyofumi Takahashi
