Publication number: 20040253891Abstract: For a protective garment, such as a protective coat for a firefighter, a composite structure comprises an outer shell, a moisture barrier within the outer shell, a moisture absorber, which absorber may incorporate a superabsorbent polymer, within the moisture barrier, and an innermost layer within the moisture barrier, wherein the innermost layer is hydrophobic but is moisture-pervious. In one contemplated embodiment, the innermost layer is made from synthetic, hydrophobic fibers, which fibers are woven so as to be moisture-pervious and which fibers are surfactant-treated so as to promote their being moisture-pervious. In another contemplated embodiment, the innermost layer is made from a sheet of a synthetic, hydrophobic material, which sheet is apertured so as to be moisture-pervious. In another contemplated embodiment, the innermost layer is made from natural fibers, which fibers have a hydrophobic finish and which fibers are woven so as to be moisture-pervious.Type: ApplicationFiled: July 19, 2004Publication date: December 16, 2004Inventors: Alan W.

Patent number: 6806215Abstract: A composite structure for a protective garment, such as a protective garment for a firefighter, has a moisture absorber, a moisture barrier and an outer shell. The moisture barrier is disposed outwardly in relation to the moisture absorber, while the outer shell is disposed outwardly in relation to the moisture barrier. The moisture absorber has a fibrous matrix incorporating a superabsorbent polymer, as particles or as fibers, and is disposed between an inner cover pervious to moisture and an outer cover. The inner and outer covers may be quilted so as to segregate discrete regions of the fibrous matrix.Type: GrantFiled: May 20, 2002Date of Patent: October 19, 2004Assignee: Morning Pride Manufacturing, L.L.C.Inventors: William L.

Publication number: 20040048535Abstract: Composite structures and methods are taught relating to temperature stabilizing saddle pads, horse blankets, saddle girths, saddle seat cushions, and saddles for protection and increased performance of horses and/or riders, among other similar products. The invention provides for products that stabilize the temperature of the horse and/or the rider by absorbing heat generated by the body of the horse and/or rider when the temperature exceeds a preset temperature appropriate for the product. In this process heat energy is absorbed through phase change, resulting in a constant temperature as long as there is material that has not changed phase.Type: ApplicationFiled: September 3, 2003Publication date: March 11, 2004Inventor: Richard J.

Publication number: 20030124935Abstract: The invention relates to a flexible scrubbing material that combines at least two discrete components. One component is a continuous flexible substrate. A second component is a discontinuous abrasive layer affixed to the flexible substrate. The abrasive layer is a set of plates formed from a material different than the continuous flexible substrate. One or two flexible substrates with affixed plates can be combined with an intermediate layer such as sponge or terry cloth. The gaps between plates are relatively large and are generally larger than one-third the largest plate dimension. The flexible substrate can be tightly woven fabric that can be printed with visually attractive colors, patterns and images. The plate material is a printable material that subsequently solidifies, such as epoxy. The inventions include associated methods of use and manufacture.Type: ApplicationFiled: October 17, 2002Publication date: July 3, 2003Inventors: Nicole Smith, Young Hwa Kim, Hong Ji, Young Lin Kim
