Patent number: 9793520Abstract: Battery covers and methods for producing battery covers are described. One battery cover described herein includes a single sheet of material formed into a substantially rectangular box shape with an opening formed along one side, the rectangular box shape capable of being folded into a flattened shape for transportation and the material including a flexible laminate of at least one layer of synthetic fiber and a polymer film layer. The material has a thickness and other properties such that when the battery cover is unfolded, the material substantially maintains the rectangular box shape, and when the battery cover is folded into the flattened shape, the material maintains a spring force such that, unless restrained, the battery cover would unfold to the rectangular box shape.Type: GrantFiled: January 31, 2014Date of Patent: October 17, 2017Assignee: Carcoustics TechConsult GmbHInventors: Rainer Knapp, Gerald Fitzgerald, Axel Boehme, Graydon Stuckey, Tony Rasegan, Lucero Guzman Gaytan, Eric Stuckey

Publication number: 20150158267Abstract: Embodiments of heat shields are provided, as well as methods for producing the heat shields. One two-layer heat shield described herein includes a first layer of aluminum having opposite first and second surfaces and a second layer of a synthetic fiber material fixedly attached to the second surface of the first layer. A pattern is formed in the second layer that has a higher compression and a smaller thickness than other locations of the second layer, the pattern providing structural support for the first layer.Type: ApplicationFiled: December 5, 2013Publication date: June 11, 2015Inventors: Graydon Stuckey, Tarah A.

Patent number: 7632559Abstract: Expandable sealant and baffle compositions and methods of forming and using such compositions are provided wherein the compositions comprise a first thermoplastic resin, an epoxy resin, preferably a second thermoplastic resin different from the first thermoplastic resin, and optionally a compound selected from the group consisting of pigments, blowing agents, catalysts, curing agents, reinforcers, and mixtures thereof. The resulting compositions are formed as self-sustaining bodies which can be heat-expanded into a lightweight, high strength product for sealing hollow structural members of vehicles, substantially decreasing the noise which travels along the length of those members as well as strengthening those members with minimal increases in their weights. In a preferred embodiment, the first thermoplastic resin is an SBS block co-polymer, the epoxy resin is a bisphenol A-based liquid epoxy resin, the second thermoplastic resin is a polystyrene, and the reinforcer is hydrated amorphous silica.Type: GrantFiled: January 16, 2004Date of Patent: December 15, 2009Assignee: Sika Technology AGInventors: Chin-Jui Chang, Gerald Fitzgerald

Publication number: 20060073266Abstract: A physical barrier having a carrier device and a sealer material applied to the carrier device. The sealer material is configured to expand when it is activated. In its pre-activation state, the sealer material is flowable. The sealer material is applied directly to the carrier in its pre-activation state through a dispensing orifice without being previously molded.Type: ApplicationFiled: November 21, 2005Publication date: April 6, 2006Inventors: Robert Myers, Gerald Fitzgerald, Cheong Kow, Randy Stratman

Patent number: 6475577Abstract: A reinforced structural member is provided which includes a reinforcing member received in the cavity of a structural member. The reinforcing member includes a carrier having divergent, intersecting legs which preferably engage and rest upon the structural member, a thermally expandable reinforcing material, and a fastener for coupling the reinforcing material to the carrier. The thermally expandable reinforcing material is preferably provided as separate elements positioned on the carrier, whereby upon activation by heat, the expandable material melts, foams and expands so that after curing, the structural member is bonded to the carrier. The shape of the carrier in combination with the expanded reinforcing material serves to stiffen and reinforce the structural member. The thermally expandable material is preferably initially dry and non-tacky, and the fasteners serves to maintain the relative position of the reinforcing material elements on the carrier prior to activation of the reinforcing material.Type: GrantFiled: February 7, 2000Date of Patent: November 5, 2002Assignee: Sika CorporationInventors: Gregory W. Hopton, Norman E. Blank, Gerald Fitzgerald, Randy Stratman, Chin-Jui Chang

Patent number: 6305136Abstract: A reinforcing member for a structural component such as a rail or channel of a vehicle is provided which includes a carrier and a thermally expansible structural reinforcing material element which is fastened to the carrier by mechanical fixation or an adhesive. The mechanical fixation may be provided by a flange or other mechanical connection on the carrier or by a fastener such as a push pin extending through aligned holes and openings in the carrier and foamable material. The push pins are preferably of a synthetic resin material which more closely approximates the heat conductivity of the foamable material when the latter is activated by heat, and is sufficiently yieldable to absorb impacts to the foamable material during installation.Type: GrantFiled: January 31, 2000Date of Patent: October 23, 2001Assignee: Sika CorporationInventors: Gregory W.

Patent number: 6199940Abstract: A reinforcing member for receiving thereon a thermally expansible reinforcing material includes a tubular carrier and a fastener mechanically affixing the reinforcing material to the carrier. The tubular carrier preferably has a continuous arcuate wall with the reinforcing material received on the exterior thereof. The reinforcing material may be provided as a plurality of longitudinally spaced annular elements, an elongated sleeve, or a plurality of prism-shaped elements. Upon heating, the reinforcing material expands and bonds the carrier to the structural member to provide additional strength and stiffness.Type: GrantFiled: January 31, 2000Date of Patent: March 13, 2001Assignee: Sika CorporationInventors: Gregory W.

Patent number: 4189878Abstract: In a house structure in which insulating material is to be laid in between and over the attic floor joists, an insulation vent is provided in spaced relation to the roofing boards to allow for free flow of ventilating air between the soffit and the interior of the attic above the insulating material and along the roof boards. This insulation vent is sold flat. To be installed it is folded on pre-scored crease lines, first to form an elongated trough consisting of a rectangular roof clearing sheet and two upwardly extending roof contacting spacer flanges. A lower end portion of the roof clearing sheet is folded down to become a wall sheathing contact sheet, and the flanges which fold down with it are stapled to the roof rafters to hold the roof clearing sheet and sheathing contact sheet in place.Type: GrantFiled: April 15, 1977Date of Patent: February 26, 1980Inventor: Gerald A.
