  • Patent number: 8322115
    Abstract: A formwork assembly is adapted to receive concrete to produce structures such as wall structures. The formwork includes PVC tubular form elements having recessed female engagement portions. The female engagement portions are adapted to receive respective male engagement portions. An octagonal form element has a female engagement portion positioned at each vertex between adjacent sides. A recessed female engagement portion is closed to the interior of the form element but open to the exterior of the form element. Thus, the form element includes a plurality of vertices open to the exterior. The form elements also include male engagement portions at an open side. Wall panels, corner panels, and joint connectors can also include the male engagement portions. The male engagement portions and female engagement portions are adapted to mate to form a formwork arrangement having a substantially flat exterior wall. A formwork assembly can additionally include concrete flow apertures and insulation.

  • Patent number: 8273283
    Abstract: A method of making a finely textured molded article is disclosed. The method utilizes properties of the compound being molded, such as impact toughness and melt flow index. Poly(vinyl halide), particularly polyvinyl chloride), articles can be custom-injection-molded using the method, in order to simulate the appearance of original metal, glass, or wood articles. Consumer, transportation, building construction, and other industries can benefit from durable plastic articles that simulate the more fragile articles.

  • Patent number: 8003726
    Abstract: Chain-extended nanonylon is made from the reaction of in-situ polymerized nanonylon and chain-extending agents. Knowing the viscosity/shear rate curve for a thermoplastic polymer to be replaced, such as nylon, the method of the present invention allows via adjustment of organoclay concentration and chain extension of the nylon polymer and other reaction factors to achieve a chain-extended, in-situ polymerized nanonylon to have a viscosity/shear rate curve that essentially matches the viscosity/shear rate curve for that neat nylon within a commercially operable shear rate.

  • Patent number: 7973099
    Abstract: A pre-processed polymer composite is disclosed comprising a heat-sensitive polymer resin particle; particles of colorant or functional additive in association with the heat-sensitive polymer resin particle; and a thermoplastic encapsulant to form a film around the associated polymer and colorant or functional additive particles. The method of making the polymer composite avoids a melting of the heat-sensitive polymer resin particles, which avoids contributing to heat history of the polymer prior to extrusion or molding into the form of the final plastic article.

  • Patent number: 7972678
    Abstract: A molded thermoplastic product is disclosed. The product has an outer surface with a matte finish. The matte finish is produced by the combination of an etched mold in which the product is molded to physically affect the outer surface and a colorant compounded in the thermoplastic to chemically affect the outer surface. The colorant provides a diffused translucency. The etching adds tactile texture. The product is made by blow-molding techniques. Containers such as shampoo bottles can benefit from such visual and tactile sensations for the purpose of creating a trade dress for a consumer product.
