Patents by Inventor Colleen W. Cordova

Colleen W. Cordova has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4960431
    Abstract: Aqueous overfinish compositions, yarns treated therewith, and methods of producing wet abrasion resistant cordage from the yarn are all disclosed. One of the compositions includes an oxidized polyethylene emulsified with a nonnitrogen, nonionic emulsifier and neutralized with an alkali hydroxide, and a compound selected from the group consisting of a siloxane of the comonomers dimethyl and 3-[(2-aminoethyl)aminopropyl], and an amide melamine wax. An alternate finish composition comprises an oxidized polyethylene, neutralized with ammonium hydroxide and emulsified with a non-nitrogen, nonionic emulsifier. Yarn treated with this alternate finish has enhanced wet abrasion resistance. Yarns of this invention are ideally suited for heavy ropes and other industrial cordage applications where wet and dry abrasion resistance and strength are desirable.

  • Patent number: 4880704
    Abstract: The invention relates to a high tenacity reinforcing fiber having improved partitioning properties selected from the group consisting of polyester, aliphatic polyamide, and combinations thereof, for reinforcing plastic composites, said fiber being coated to enhance stiffness of the fiber for cutting with(a) 3 to 12 weight percent, based on weight of fiber of carboxyl-terminated, oil-free alkyd resin which is the reaction product of at least one aliphatic glycol containing 2 to 12 carbons with a combination of aromatic di- or trifunctional carboxylic acids and, optionally, an unsaturated aliphatic carboxylic acid, said resin having a degree of esterification below the gel point of the resin, and(b) 0.5 to 2 weight percent vinyl chloride copolymer having a glass transition termperature of greater than about 60.degree. C.

  • Patent number: 4695509
    Abstract: Fiber-reinforced thermoset polyurethane composites display enhanced impact strength when sufficient amounts of a high tenacity aliphatic polyamide fiber characterized by a drawn denier of 4 to 8 denier per filament; a thermal shrinkage of up to about 14 percent; an elongation of from less than 28 percent; and a tenacity of at least 5.5, preferably at least 7 grams per denier, are incorporated into the composite. The process of producing such composites, including reinforced reaction injection molding processes, resin transfer molding processes, and casting process are improved by a reduction in equipment wear resulting from the incorporation of the specified polyamide fiber.

  • Patent number: 4548866
    Abstract: A yarn containing hollow synthetic polymer filaments having an outside diameter ranging from 0.02 to 0.20 mm is provided. The yarn has a filament to yarn strength translation efficiency of at least 98 percent and a yarn to cord strength translation efficiency of at least 90 percent. The yarn has utility in medical products, self-buoyant assemblies, ropes and braids, filtration fabrics, textured products, tire cord and ballistics.
