Patent number: 7111648Abstract: A terry fabric comprises a plurality of repeat units of interwoven warp and weft threads. Each of the repeat units comprises a set of ground warp threads, a set of pile warp threads, and a set of weft threads. The ground warp threads are woven tightly with the weft threads to form a substrate, and the pile warp threads are loosely interwoven with the weft threads to form pile loops. At least two adjacent weft threads are interwoven with the ground warp threads and the pile warp threads in an identical pattern (typically in a single machine cycle). In this configuration, fabrics with different properties can be producing in similar manufacturing duration, particularly if weft threads of different thread weight are employed.Type: GrantFiled: February 13, 2004Date of Patent: September 26, 2006Assignee: Springs Industries, Inc.Inventors: Paul H. Mitchell, John V. Wirth

Patent number: 6846534Abstract: Described is a membrane comprising a microlayer polymeric composite having at least about 10 microlayers. The microlayers are each individually up to about 100 microns thick and alternate between at least one gas barrier material and at least one elastomeric material. The membrane can be formed into a pressurized bladder or cushioning device for many applications, including footwear and hydropneumatic accumulators.Type: GrantFiled: May 23, 2003Date of Patent: January 25, 2005Assignee: Nike, Inc.Inventors: Henry W. Bonk, David J. Goldwasser, Paul H. Mitchell

Patent number: 6764629Abstract: The present invention relates to laminated membranes formed by multi-layer processing techniques including alternating layers of thermoplastic urethane and a copolymer of ethylene and vinyl alcohol. The membranes are characterized in that hydrogen bonds are formed between the layers of thermoplastic urethane and the copolymer of ethylene and vinyl alcohol. The membranes are characterized in that hydrogen bonds are formed between the layers of thermoplastic urethane and the copolymer of ethylene and vinyl alcohol.Type: GrantFiled: May 23, 2003Date of Patent: July 20, 2004Assignee: Nike, Inc.Inventors: Erwin C. Shepard, DeWayne R. Hartlerood, Paul H. Mitchell

Patent number: 6521305Abstract: Products in the form of cushioning devices made from flexible membranes employing at least one layer including thermoplastic urethane and at least one layer of a copolymer of ethylene and vinyl alcohol are inflatable to a relatively high pressure. The cushioning devices maintain the internal inflatant pressure for extended periods of time by employing a phenomenon referred to in the industry as diffusion pumping. Ideally, the cushioning devices of the present invention can be permanently inflated with gases such as nitrogen or air.Type: GrantFiled: September 14, 1999Date of Patent: February 18, 2003Inventors: Paul H. Mitchell, James C. Sell, Jr., Henry W. Bonk

Publication number: 20010014164Abstract: A printstream processor separates documents, e.g. in a printstream or batch, into a physical delivery printstream and an electronic delivery printstream based on delivery preferences stored in a database. The documents in the physical delivery printstream are printed and combined with physical inserts for physical delivery, e.g. by the U.S. Postal Server. The documents in the electronic delivery printstream are combined with electronic inserts for electronic delivery, for example, via electronic mail, facsimile, pager, or to a server on World Wide Web.Type: ApplicationFiled: November 12, 1997Publication date: August 16, 2001Inventors: EDWARD P. DANIELS, JOHN F. KWANT, PAUL H. MITCHELL, JOHN G. RAHRIG, KARL SCHUMACHER, CLARE E. WOODMAN
