Patent number: 7350411Abstract: A wind sensor device consisting of a plurality of light weight, flexible, high tensile strength filaments attached to and depending from a malleable elongated body structure, such as a wire. The filaments are blown by the wind, thus indicating direction. The flexible body structure is used to attached the device to a hunter's rifle, gun, bow, tree, or other nearby object such as a branch, thus freeing the hunter's hands for other tasks.Type: GrantFiled: February 2, 2006Date of Patent: April 1, 2008Inventor: Christopher P. Anderson

Patent number: 7335417Abstract: A novel olefin textile fabric knitted woven and non-woven that in one aspect of the invention is disperse dyed to a light, medium or deep solid shade. In another aspect, the textile fabrics of the present invention are manufactured using olefin yarns that contain variable amounts of dye acceptor additives. A fabric with more than one tone of a color is dyed in a single dye bath. The fabrics and yarn using this invention can be processed using conventional spinning, weaving, knitting, web forming machines and will dye using existing dyeing and finishing systems. This invention is of particular value in the apparel and home furnishings industry.Type: GrantFiled: March 11, 2005Date of Patent: February 26, 2008Assignee: Aquadye Fibers, Inc.Inventor: Edward J. Negola
