Patent number: 6849142Abstract: The female component for engaging a complementary hook component in a refastenable fastening device is capable of engaging a hook component that has flexible, resilient individual hook elements. The female component comprises at least two, and preferably three zones or layers. These include a first zone for admitting and engaging at least some of the hooks of the complementary hook component (the “entanglement” zone), a second zone for providing space for the hooks to occupy after they have been admitted by the entanglement zone (referred to as the spacing zone), and a backing adjacent to the spacing zone. The present invention also provides a fastening device having a hook fastening component and a female component that comprises the multi-layer female component of the present invention. The present invention also relates to disposable articles and more particularly to a disposable diaper having such an improved fastening device.Type: GrantFiled: October 19, 1993Date of Patent: February 1, 2005Assignee: The Procter & Gamble CompanyInventor: David Joseph Kenneth Goulait

Publication number: 20040216854Abstract: Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products.Type: ApplicationFiled: May 26, 2004Publication date: November 4, 2004Applicants: Nile Fiber Pulp & Paper, Inc., Washington State University Research FoundationInventors: Ernett Altheimer, Michael P.

Publication number: 20040206441Abstract: A method of coating disc brake pads to obscure and seal minor surface imperfections, thereby reducing scrap rates. A preform of friction lining material is coated prior to molding and curing the preform and bonding the same to the backing plate to form the brake pad assembly. The preform is coated with an aqueous composition containing a solids mixture of 5-50 vol. % resin and 50-95 vol. % non-resin solids. Advantageously, the coating composition has a 5-30 vol. % solids mixture content, which solids mixture includes 15-25 vol. % resin, 0-10 vol. % powdered elastomer, 5-15 vol. % carbon black, 20-50 vol. % inorganic fillers, 5-15 vol. % organic fibers and 1-10 vol. % inorganic flake material.Type: ApplicationFiled: April 18, 2003Publication date: October 21, 2004Applicant: Delphi Technologies, Inc.Inventor: Robert Anthony Lamport

Patent number: RE39354Abstract: A laser-sinterable powder product has been prepared having unique properties which allow the powder to be sintered in a selective laser sintering machine to form a sintered part which is near-fully dense. For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder. In addition to being freely flowable at a temperature near its softening temperature, a useful powder is disclosed that has a two-tier distribution in which substantially no primary particles have an average diameter greater than 180 ?m, provided further that the number average ratio of particles smaller than 53 ?m is greater than 80%, the remaining larger particles being in the size range from 53 ?m to 180 ?m. A powder with slow recrystallization rates, as evidenced by non-overlapping or slightly overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10° C. to 20° C.Type: GrantFiled: October 24, 2002Date of Patent: October 17, 2006Assignee: 3D Systems, Inc.Inventors: Elmer Douglas Dickens, Jr., Biing-Lin Lee, Glenn Alfred Taylor, Angelo Joseph Magistro, Hendra Ng, Kevin P.
