Patent number: 6972376Abstract: In order to provide a flexible oxide superconducting cable which is reduced in AC loss, tape-shaped superconducting wires covered with a stabilizing metal are wound on a flexible former. The superconducting wires are preferably laid on the former at a bending strain of not more than 0.2 %. In laying on the former, a number of tape-shaped superconducting wires are laid on a core member in a side-by-side manner, to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer in a side-by-side manner, to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and provides flexibility to the superconducting wires and the cable formed therewith.Type: GrantFiled: December 15, 2004Date of Patent: December 6, 2005Assignee: Southwire CompanyInventors: Raburn L. Hughey, Uday K. Sinha, David S. Reece, Albert C. Muller

Patent number: 5096764Abstract: A printable carpet material which carpet material comprises a fibrous face, a primary backing sheet and a backing layer comprising a bitumen backing composition containing a thermosetting amount of a hydroxyl-terminated polybutadiene-diisocyanate urethane polymer to provide a heat stable carpet material subject to a wet stream printing process without substantial carpet material edge loss or distortion. A method of preparing a carpet material which is steam printable and which method comprises applying as a backing layer to a fibrous carpet material a bitumen backing composition containing a thermosetting amount of a hydroxyl-terminated polybutadiene-diisocyanate urethane polymer which permits the carpet material so prepared to be subject to wet, steam printing processes without substantial carpet material edge loss or distortion.Type: GrantFiled: September 12, 1990Date of Patent: March 17, 1992Assignee: Heuga Holding BVInventors: C.
