Patent number: 7645494Abstract: The invention relates to a method that involves (a) removing graphite from at least one surface of a metal graphite composite material; (b) chemically cleaning or plasma etching the surface of the metal graphite composite material; (c) applying a metal-containing material to the surface of the chemically cleaned or plasma etched metal graphite composite material, and thereby forming an intermediate layer; (d) applying a metal coating on the intermediate layer, and thereby forming a composite material. The invention also relates to a composite material comprising (a) a metal graphite composite substrate having at least one surface that is substantially free of graphite; (b) a metal-containing intermediate layer located on a surface of the substrate; and (c) a metal coating on the intermediate layer.Type: GrantFiled: March 27, 2008Date of Patent: January 12, 2010Assignee: H.C. Starck Inc.Inventors: Richard Wu, James Cornie, Stephen Cornie, Hank Breit, Larry Ballard, Richard R. Malen, Prabhat Kumar, John Shields, Robert Desberg

Publication number: 20080265403Abstract: A hybrid package for heat sinking a device is formed of a graphitic material that defines a plurality of cavities for cast-in-rivets and that defines at least one cavity for a cast-in-rivet via. The graphitic material is pressure infiltrated with a molten metal alloy so as to form a composite material with a plurality of cast-in rivets that increases at least one of the through-plane conductivity and the strength of the hybrid package and that forms at least one cast-in-rivet that increases an in-plane thermal conductivity of the hybrid package.Type: ApplicationFiled: December 23, 2005Publication date: October 30, 2008Applicant: METAL MATRIX CAST COMPOSITES, LLCInventors: James Allen Cornie, Stephen Shawn Cornie, Yuejian Chen, Larry Ballard

Patent number: 5429073Abstract: A degradable, reusable, partially synthetic and partially non-synthetic bedding material for animals includes a plurality of flexible monofilaments formed from a blend of a thermoplastic polymer and starch. An effective amount of at least one transition metal salt may also be added to enhance ultraviolet and/or thermal degradation. The partially synthetic animal bedding has an appearance, texture and sound very similar to that of natural straw, but can be cleaned and reused repeatedly. The partially synthetic straw-like material is inert as far as digestibility and is degradable when exposed to sunlight and dry heat, and is biodegradable and compostable thereby providing for relatively easy disposal.Type: GrantFiled: October 26, 1993Date of Patent: July 4, 1995Assignee: Shakespeare CompanyInventor: Larry Ballard

Patent number: 4992515Abstract: A cross-linkable nylon composition and is useful for coated sewing threads. The compositions comprises a nylon terpolymer; from about 1 to 20 percent by weight of a low residual formaldehyde cross-linkable resin, based upon the weight of the terpolymer; from about 0.1 to 10 percent by weight of a catalyst for the cross-linkable resin, based upon the weight therof and a suitable solvent for the terpolymer in an amount sufficient to form at least a 5 percent solution by weight of the terpolymer. Coated sewing threads comprise a sewing thread and from about 0.1 to 20 percent by weight of the cross-linked nylon composition, based upon the weight of the thread.Type: GrantFiled: January 9, 1990Date of Patent: February 12, 1991Assignee: Shakespeare CompanyInventor: Larry Ballard

Patent number: 4806407Abstract: Polyphenylene sulfide blends with melt extrudable polymers form novel monofilaments. The monofilament is prepared by extruding a mixture of the linear polyphenylene sulfide and the melt extrudable polymer to form a monofilament blend, quenching the monofilament and thereafter drawing the monofilament to a ratio of from about 3:1 to 6:1. The resulting filament can be employed for the manufacture of fabric.Type: GrantFiled: April 11, 1988Date of Patent: February 21, 1989Assignee: Shakespeare CompanyInventors: David B. Skinner, Larry Ballard
