Appeal No. 2005-0288 Page 7 Application No. 10/075,786 resistance, and is compatible with the environment for which it is intended. In the BACKGROUND OF THE INVENTION section, Holland discusses the disadvantages of the standard cargo cover constructed from canvas or from vinyl coated nylon or polyester. Then, in the SUMMARY OF THE INVENTION section, Holland teaches that: The present invention is directed to an improved fabric and fabric cargo cover fabricated from yarns formed of long chain expanded polyethylene fibers. One source of such fibers is sold by Allied Signal under the trademark "Spectra". These fibers are sometimes referred to as "ultra high molecular weight polyethylene" within the scope of U.S. Pat. No. 4,413,110. The specification and teachings of this patent are incorporated by reference. Such a fabric has a high level of tear-resistance, abrasion resistance, cut-and-stab resistance, and chemical and cold resistance to improve the strength and durability of the fabric. In addition, such fabric is about one-third the weight of such conventional fabrics as vinyl coated nylon. This results in fuel savings of about $30 per year for each pound of fabric used. Holland teaches (column 3, lines 16-24) that: The improved fabric is intended to be used as a fabric to cover cargo containers, luggage trailers, and truck openings. While the improved fabric can be used for a variety of purposes, the ensuing description is directed to a fabric cover for a cargo container. Accordingly, it is an object of the present invention to provide a durable, lightweight fabric that has improved tear-strength, cut-and-stab resistance, abrasion resistance, cold resistance, and chemical resistance. Holland further teaches (column 6, lines 3-9) that: The present invention has been described as utilized on a cargo cover 10 for a cargo container 12. The fabric 30 used for cargo cover 10 may also be used for luggage trailer curtains and truck closure curtains generally covered by fabricPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
