  • Patent number: 7217456
    Abstract: A composite textile fabric for rapidly moving moisture away from the skin, and for retaining body heat, is provided. The composite fabric includes an inner fabric layer made of a yarn comprising a plurality of fibers primarily of polyester or other synthetic yarns which have been rendered hydrophilic, and an outer fabric layer made of a yarn comprising a plurality of fibers primarily of polyester or other synthetic yarns which have also been rendered hydrophilic. The inner fabric layer and the outer fabric layer are formed concurrently by knitting a plaited construction so that the layers are distinct and separate, yet integrated one with the other. The yarn fibers of the inner fabric layer are embedded with particles of a refractory carbide, or may be treated by metal vapor deposition to enhance the retention of body heat.

    Abstract: An improved heat shield provides for reduced noise transmission of vehicular engine components is disclosed. The heat shield has three layers; a first sheet layer, a center insulation layer, and a second sheet layer. The insulation layer is positioned between the first and second sheet layers. The first sheet layer is defined by a variable shaped periphery that is folded over the periphery of the second sheet layer to form a hem having a variable length around the heat shield. The variable length serves to reduce uneven strain in the hem area experienced during crush forming the heat shield into the final shape. Further, the variable length of the hem also serves to alter the resonate frequency of the heat shield in specific areas to reduce vibration and improve acoustical properties.

  • Patent number: 6821595
    Abstract: A composite material panel having alternating layers of wood veneer with recycled or waste material. The layers are sandwiched together. The technique involves forming the composite material layer by layer and employing materials in each layer that are suited to satisfy requirements for specific kinds of construction. The layer of recycled or waste material is preferably flexible and has memory. Some examples include plastic straw, bars from plastic, tires or metal, balls from plastic or tires, sheet from plastic, tires or metal, air bubble cushioning from plastic. The metal is exemplified by aluminum and tin.

  • Publication number: 20040192134
    Abstract: A fabric for use in safety apparel comprising yarns spun from a blend of staple fibers. At least 60 percent of the staple fibers are flame resistant fibers and up to 40 percent are non-flame resistant fibers. At least one dye type is applied to the fabric and is selected to dye both the flame resistant and non-flame resistant fibers in the blend. When dyed, the fabric meets both the American National Standards Institute standard ANSI/ISEA-107 minimum conspicuity requirements for occupational activities for high-visibility safety apparel and the American Society for Testing and Materials standard ASTM F-1506 for flame resistance.

  • Patent number: 6793993
    Abstract: A fire resistant resilient insulation assembly, includes: a resilient insulation and a fire resistant polymeric film forming a tubular envelope surrounding the resilient insulation. The fire resistant polymeric film includes: 50 to 80 weight percent high density polymeric material; 5 to 45 weight percent linear low density polymeric material; 5 to 25 weight percent fire retardant concentrate (a halogen and a synergist in a polymeric carrier); 0 to 5 weight percent UV stabilizer; and 0 to 10 weight percent pigment. Preferably, the film is a two layer coextruded film with the outer layer being a predominately linear low density polymer that provides a good finish for printing and a relatively high coefficient of friction to improve the handling of the film during the encapsulation of the blanket. The inner layer is predominately high density polymer that provides the coextruded film with the impact strength and tear resistance required for processing and handling.

  • Patent number: 6787214
    Abstract: Fire-retardant sheet element can be composed of several fire protection glass plates (2, 3). Lateral edges (9, 10) of adjacent glass plates (2, 3) therein abut one another. Into the interspace (26) between lateral edges (9, 10) a sealing configuration (7) is installed. This comprises an addition element (22) and elastic sealing elements (23, 24). The glass plates (2, 3) comprise several glass panes (16) and interspaced fire protection layers (18). These fire protection layers (18) do not extend up to the edges (9, 10) and are sealed in the regions of the lateral edges with a barrier material (20). No additional frame elements for covering the interspace (26) and for sealing are necessary.
