Patent number: 5773108Abstract: A containment structure for radially deployable devices in the form of a self-coiling composite band. The composite band is fabricated as a lay up of epoxy resin-impregnated ply layers of cloth material that are wrapped about a mandrel and cured in a specific ordered sequence.

Patent number: 5704402Abstract: The woven structure for an air bag is designed to have an air permeability which does not increase by more than about fifty percent when the fabric is subjected to substantially equivalent tension forces in both the warp and fill. This is accomplished by a multiple warp harness arrangement using combinations of twill and basket weave pattern components. This weave construction does not only avoid substantial increases in permeability over a range of biaxial tensions but also may result in a permeability decrease when subjected to tensions which approximate those applicable during actual air bag deployment.Type: GrantFiled: April 1, 1996Date of Patent: January 6, 1998Assignee: Milliken Research CorporationInventors: Derek L. Bowen, Charles L. Bower, John A. Sollars, Jr.

Patent number: 5700531Abstract: A pull-activated container adapted to hold a fluid, volatile solid, or absorbent for a fluid wherein at least a portion of the container includes a laminate which, in turn, includes a first layer, a second layer, a third layer, and a grasping means. The first layer is a fibrous sheet, the second layer is a film having a first side and a second side, and the third layer is a porous fibrous sheet. The third layer is inside the container. The first layer is bonded to the first side of the second layer and has a first bonding strength and the third layer is bonded to the second side of the second layer and has a second bonding strength. For example, the first bonding strength may be greater than the second bonding strength to an extent sufficient to permit selectively removing the first and second layers from the third layer without tearing the third layer. The grasping means is affixed to the first layer and has a third bonding strength which is greater than the second bonding strength.Type: GrantFiled: November 17, 1995Date of Patent: December 23, 1997Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Gunilla Elsa Gillberg-LaForce, Kevin George Hetzler, Rob Lee Jacobs

Patent number: 5700532Abstract: A silicone rubber composition that is capable of adhering to the surface of various kinds of substrates, in particular woven fabrics or the like in the absence of an adhesion promoter or coupling agent. The composition of the present invention includes a dual catalyst system which enhances the cure rate of the silicone compound. Strong adhesion of the silicone rubber coating composition to the substrate is achieved at high coating speeds using a mixture of an organopolysiloxane, an organohydrogenpolysiloxane resin, a platinum catalyst, and a peroxide curing agent. The silicone rubber composition is particularly suitable as a coating for airbag fabrics.Type: GrantFiled: November 17, 1995Date of Patent: December 23, 1997Assignee: Highland Industries, Inc.Inventor: Joseph J. Chiou

Patent number: 5698477Abstract: The present invention provides an adhesive cloth tape for bundling the component wires of a wiring harness for use, for example, on an automobile. Conventional adhesive polyvinyl chloride tapes and adhesive acetate cloth tapes have problems that wiring harnesses bundled by these adhesive tapes generate fluttering and rustling noise while the automobile is running, and conventional adhesive cotton cloth tapes reduce the efficiency of bundling work because these tapes have high tear strength, though their noise preventing performance is excellent. The present invention provides an adhesive cloth tape solving the foregoing problems in the conventional adhesive cloth tapes, having a tensile strength of 8 kgf/19 mm or higher with respect to the direction of its length, and comprising: a woven base cloth of 0.Type: GrantFiled: January 17, 1995Date of Patent: December 16, 1997Assignees: Sliontec Corporation, Sumitomo Wiring Systems, Ltd.Inventors: Takashi Iwamaru, Shigeo Uchida, Minoru Fujita
