  • Patent number: 5863642
    Abstract: A water resistant and vapour phase corrosion inhibitor composite material for wrapping around metallic items for protection and to reduce corrosion during storage and transportation. The composite material comprises a high strength, tear resistant, flexible scrim, a low density layer impregnated with a solid form vapour phase corrosion inhibitor, and a barrier layer to reduce the transmission of water, water vapour, oxygen and other environmental gases through the composite material. The barrier layer also reduces the atmospheric loss of gaseous vapour phase corrosion inhibitor from around the wrapped item. Each layer is formed from a polyolefin material to create a multi-layered polyolefin composite material that is easily recyclable.

  • Patent number: 5863844
    Abstract: An improved washing implement which exhibits superior softness, while also retaining good resiliency. To achieve the improved softness and resiliency of the improved washing implement an improved open cell mesh is provided which is softer and sufficiently resilient as a result of its controlled cell structure parameters. In preferred embodiments, the controlled physical parameters of the open cell mesh include basis weight, cell count, node count, node length and node diameter. Additionally there is provided a method of testing the mesh's resistance to an applied load, which provides an additional parameter for characterizing the mesh of the present invention.

  • Patent number: 5834381
    Abstract: A non-halogenated, tri-laminate fabric for automotive security shades or covers, comprising a layer of reinforcing fabric scrim juxtapositioned between at least two layers of a thermoplastic olefin film comprised of a rubber modified polyolefin compound, said layers being thermally bonded together to form a fire retardant, nontoxic tri-laminate fabric. The rubber modified polyolefin is a rubber modified polypropylene or polyethylene homopolymer and copolymer. The rubber is natural or synthetic. The preferred thermoplastic olefin film has characteristic melt peaks at temperatures ranging between about 61.degree. C. and 100.degree. C. and between about 105.degree. C. and 168.degree. C., with melt peaks forming preferably at about 86.degree. C. and 142.degree. C. Acceptable thermal lamination of the layers occurs at temperatures ranging between about 120.degree. C. and 140.degree. C.

  • Patent number: 5827787
    Abstract: A decorative and translucent weatherable fabric for covering outdoor backlit structures is provided which includes a reinforcing scrim layer, an inner protective layer formed of a translucent white PVC applied to one side of the scrim layer, and a thicker substrate layer applied to the opposite side of the scrim layer. The substrate is also preferably a substantially translucent white PVC polymer. In one embodiment of the fabric for use with a reader panel of the awning, an outer transparent layer is adhered to the substrate layer and has UV resistant properties. A weatherable pressure sensitive decorative film is applied to certain portions of the transparent layer in a predetermined graphical pattern to create a foreground image. A second pressure sensitive decorative film may be applied to certain other portions to create a background image of a different color.

  • Patent number: 5679437
    Abstract: A peelable roadway marking tape has a multi-layer structure which provides durability and ease of removal. The marking tape includes a top layer of pigmented vinyl paint with reflective glass beads incorporated therein applied to an intermediate backing layer of either aluminum or vinyl. The backing layer is then laminated to a polyester mesh reinforcement layer, and a pressure-sensitive adhesive hot melt is applied to the under side surface of the mesh for attachment to the roadway surface. In an alternate embodiment of the invention, a layer of high density polyethylene is laminated between the mesh layer and an aluminum backing layer.
