  • Publication number: 20040009331
    Abstract: A method for making an article of syntactic foam includes spreading a layer of a mixture including particulate resin and microballoons across a surface. At least a portion of the mixture is selectively heated so as to cause the portion to assume a desired shape for at least part of the article. The heating is performed Until the resin flows and wets the microballoons to form a solid mass. The method allows a finished part to be fabricated in a single sintering operation with little or no subsequent machining.

  • Patent number: 6670012
    Abstract: A process for producing a multicolored coverstock (10, 20, 72) providing at least two thermoplastic or thermoplastic olefin sheets (12, 14, 58). Each of the sheets includes a different color. The process includes directing the sheets into a position where the edges (24, 26) of the sheets overlap. The sheets are laminated together and are laminated to a foam substrate (22, 60) by directing the sheets and the foam substrate through an embossing nip (72). The embossing nip is further operative to impart an embossed surface in the sheets (18). The resulting laminated coverstock may be used in vacuum forming, low pressure molding, and compression molding of interior trim parts of automobiles and other vehicles.

    Abstract: Mechanically embossed resilient surface coverings having superior textural fidelity are prepared by mechanically embossing a polyurethane coated floorcovering before the polyurethane is cured. The mechanical embossing is conducted when the polyurethane is dry and the underlying plastic layer and the polyurethane are softened by heating. After the mechanical embossing step, the polyurethane is cured using ultraviolet (UV) light. The product can be cooled before or after UV curing. The invention is applicable to a variety of resilient surface covering products including floor and wall coverings which otherwise have a wearlayer which can be softened by heating. This includes surface coverings having the full range of decorative effects available in the art, including surface coverings which also have been, for example, chemically embossed, mechanically embossed, chemically and mechanically embossed or not embossed at all prior to application of the process of the invention.

  • Patent number: 6468629
    Abstract: This invention concerns a multilayer lining material in the form of sheeting which can be cut to size. Such lining materials are used, for example, as floor plates to cover the loading areas of utility vehicles and as floorboards for passenger vehicles. The lining material can be cut to size, so it can also be punched to obtain a shape corresponding to the loading area. A known lining material which is used as a floor plate consists of a wood fiberboard on the bottom side. A laminated material consisting of a TPO compact film (TPO=thermoplastic polyolefins) with a laminated nonwoven bonded to the wood fiberboard. Thus, the lining material consists of three layers. The known lining material has a complicated design because first a nonwoven must be laminated to the TPO compact film and then the wood fiberboard must be glued to the laminated material consisting of the TPO compact film and the nonwoven. This makes production very cost-intensive.

  • Patent number: 6387470
    Abstract: Expandable sealant and baffle compositions and methods of forming and using such compositions are provided wherein the compositions comprise a first thermoplastic resin, an epoxy resin, preferably a second thermoplastic resin different from the first thermoplastic resin, and optionally a compound selected from the group consisting of pigments, blowing agents, catalysts, curing agents, reinforcers, and mixtures thereof. The resulting compositions are formed as self-sustaining bodies which can be heat-expanded into a lightweight, high strength product for sealing hollow structural members of vehicles, substantially decreasing the noise which travels along the length of those members as well as strengthening those members with minimal increases in their weights. In a preferred embodiment, the first thermoplastic resin is an SBS block co-polymer, the epoxy resin is a bisphenol A-based liquid epoxy resin, the second thermoplastic resin is a polystyrene, and the reinforcer is hydrated amorphous silica.

  • Patent number: 6383607
    Abstract: A mouse pad with improved self-cleaning and traction features. The mouse pad is a planar structure with a parallel top control layer and a bottom anti-skid coating. Formed on the top layer is a top control layer with a plurality of alternating, equal height, prismatic and pyramidal shapes, which provide improved cleaning and traction properties. Small troughs are formed between the adjacent shapes, which collect fine dirt and dust particles that are swept from the surface of the mouse ball during use. In one embodiment, the top control surface is made of flexible material that allows the prismatic and pyramidal shapes to bend slightly when the ball of a mechanical mouse rolls over the top surface. This bending action provides improved self-cleaning and traction features. In another embodiment, the top layer is made of transparent material. An ink layer may be applied to the bottom surface of the top layer.

  • Patent number: 6379785
    Abstract: A substrate, preferably silicon, or other suitable material has a layer of glass material disposed thereon. The glass material of the present disclosure has a substantially increased uniformity due to the reduction in bubbles as well as a relatively smooth top surface. By virtue of the reduction in the number and size of the bubbles in the glass the dielectric properties of the glass are more uniform. Additionally, the fact that the surface of the glass is much more smooth reduces the potential of prior structures to have an unacceptably thin glass layer due to the need to grind the surface smooth.

  • Patent number: 6372334
    Abstract: A tri-laminate body panel stiffener includes two polymer layers with or without a backing. One of the layers is a compliant foam layer mounted against a substrate while the other layer is a rigid foam layer mounted against the compliant foam layer. In another aspect of the invention the laminate comprises a backing member having an expandable foam mounted thereto with two or more opposing edges of the laminate being of non-straight construction such as being wavy or saw tooth. A pattern of holes may be formed through the foam and backing layers.

  • Patent number: 6372076
    Abstract: The present invention relates to a process of forming a multi-layer pad of a non-woven fiber batt and a foam layer having conforming convoluted surfaces and to a multi-layer pad incorporating a non-woven fiber batt and foam layer. The process of forming a non-woven batt layer and a foam layer having conforming convoluted surfaces comprises transporting each layer along its longitudinal dimension while compressing each layer along its lateral dimension. Concomitantly with compression, each layer is cut transversely along its lateral dimension to separate each layer into an upper segment and a lower segment and to provide conforming convoluted surfaces on the segments of each layer, the convoluted surfaces comprised of upstanding projections and depressions.

  • Patent number: 6358595
    Abstract: The object of the invention is to produce a surface layer that can prevent from uncomfortable sensation upon manual handling of component such as metal chassis used in electronic devices. The surface is coated with a special paint material or a resinous coating material that include insulating material or foamed structure. For example, gaseous entrapments are incorporated in the layer by pre-mixing a foaming material in the paint, followed by foaming the layer at a high temperature. A decline in the restoring strength of the foaming material is supplemented by the top coating with the bead-containing paint.
