  • Patent number: 6764744
    Abstract: A composite fabric structure having unique visual and physical properties is described. The composite fabric includes a textile fabric layer having a visual surface and a rear surface. A layer of diffractive or retroreflective material is secured beneath the textile fabric layer, either directly or beneath a layer of substantially transparent material. The textile fabric layer is of an open or semi-transparent construction, so that light can pass through it to reach the layer of diffractive or retroreflective material and be reflected back through the layer of textile fabric, to provide a unique appearance to its visual surface. Because fabric constructions can be provided which are extremely conspicuous, they have particular utility in the formation of safety equipment and automobile components. Furthermore, the fabrics have high durability, improved hand, and in many embodiments can be stretched as well as molded.

  • Patent number: 6479117
    Abstract: A combined waterproofing sheet and protection course membrane has a water resistant film and a protective layer. The protective layer protects the film from being punctured and otherwise compromised. An adhesive layer, with a free adhesive side for adhesion to a foundation, is adhered to the film, so that the membrane can be applied to a subterranean foundation in a single step. While the foundation is being back filled, the protective layer keeps the water resistant film intact thereby maintaining the water resistant capabilities of the membrane.

  • Patent number: 6451409
    Abstract: A composite roofing material includes a final condition underlayment material having bonded thereto appropriate rows of nail tabs preferably made of thermoplastic-based material, such as low density polyethylene material, and of a contrasting color to the underlayment material. A process is used to make the nail tabs by conveying the saturated underlayment material in a continuous process past appropriate sets of nozzles that are coordinated with the speed of conveyance to deposit the tabs while in a liquid state and to form tabs of appropriate size and appropriately patterned across the underlayment surface. Each nozzle can include multiple orifices to control the width and thickness of the formed tabs. A similar process is disclosed for making other building cover materials having rows of nail tabs coinciding with standard stud spacing.

  • Patent number: 6440530
    Abstract: Lids, for example, lids for machine-lidding of, e.g., beakers, dishes, menu dishes, goblets, small packages, etc., containing a substrate material featuring, with respect to a container on which the lids are used, a smooth outward facing surface bearing printing. On the inward facing side of the lid is a sealing layer deposited by extrusion laminate coating. The sealing layer exhibits on the free surface embossing with a depth of roughness of up to 50 &mgr;m. The embossing is transferred to the sealing layer in the form of a roughness pattern on the cooling roll on depositing the laminate coating of the substrate material and extruded sealing layer. The free side of the substrate material is smooth and exhibits no embossing. Printing on the free surface is therefore of higher quality. The extruded sealing layer on the substrate material exhibits embossing on the free side. If the lids are drawn from a stack of lids, for example, in a filing machine, the embossing allows them to be separated individually.

  • Patent number: 6436159
    Abstract: A coating composition for forming abrasion-resistant, high clarity coatings is described. It has been found that a macrocrystalline or single crystal mineral abrasive can be added at high levels, about 5 to about 80 percent by weight, to art-recognized film-forming resin compositions for producing coatings exhibiting exceptional abrasion resistance and clarity. Such a coating composition is useful for application to surfaces including wood, vinyl, tile, rubber modified cement, marble, metal, plastic, and laminated surfaces.

The cured composition provides superior abrasion and impact resistance as well as protection against environmental and chemical agents. In addition, the UV curable compositions are capable of forming films on various substrates; the film has excellent compatibility and adhesion to AR coatings that are applied thereon. No primer coating is required.
