  • Patent number: 9833932
    Abstract: Systems and methods provide for forming layered structures. Textured tapes may be fabricated, having cast and/or embossed patterns that provide for desired flow characteristics in an assembly of stacked, rolled, and/or otherwise assembled tapes. In some cases, shear thinning materials may be formed into textured tapes using localized shear stress to induce shear thinning during a pattern formation. A pattern may be maintained after removal of the shear force due to the high viscosity of the material at low shear stress.

    Abstract: A method for making a polishing pad includes rotating a cylinder about a central axis. The cylinder encloses in an interior space a polymer precursor. The method also includes forming the polishing pad from at least some of a polymer formed after the polymer precursor has cured. The rotating of the cylinder may be continued until the polymer has cured. The method may include forming at least two distinct layers in the polishing pad by casting and curing sequentially at least two different polymer precursors. A system for manufacturing a polishing pad includes a centrifugal caster adapted to rotate. A polishing pad made by a method is provided.

  • Patent number: 8480393
    Abstract: A method and apparatus for a reusable resin distribution line for use in conjunction with a resin transfer molding apparatus is disclosed. The apparatus includes a soft tool and a hard tool (i.e., mold). In the illustrative embodiment, two inflatable bladders are disposed on a side of the soft tool, wherein a bridge spans the bladders. The soft tool is coupled to the bridge. When the bladders are inflated, the bridge moves away from the hard tool, drawing the soft tool away from the hard tool in the region between the bladders. This creates a temporary passage or reusable resin distribution line for distributing resin to a reinforcement constituent disposed between the soft tool and the hard tool.

  • Publication number: 20130149420
    Abstract: The present invention relates to methods and devices for the formation of articles, for example pelletized articles, for use as animal feed or otherwise. In one exemplary embodiment, the present invention provides a process of forming animal feed. The process includes forming a mixture of hydrated alginate. The process further includes forming a mixture of ingredients to be pelletized, the mixture of ingredients being placed in a preconditioning chamber of a forming device. The process further includes atomizing and injecting the hydrated alginate into the preconditioning chamber to coat the mixture of ingredients. The process still further includes pelletizing the mixture of alginate coated ingredients, wherein the volume of atomized hydrated alginate applied to the mixture of ingredients is based upon one or more characteristics of the ingredients, one or more operating conditions of the forming device or both.

  • Publication number: 20130149486
    Abstract: A method and a device for thinly coating a component on all sides are provided. A single layer is applied onto the component by casting in a casting mold, wherein during the casting process the material to be applied moves as laminar flow in the region of the decorative element. For this purpose, a casting mold consisting of a lower and an upper part is provided, in which proceeding from at least one sprue in the upper part to the side of the component to be coated a runner extends in direction of the component to be coated for filling the casting material into the casting mold, wherein in the runner in the vicinity of the component to be coated a retaining groove is provided for distributing the casting material across the width, and wherein the runner has a reduced passage subsequent to the retaining groove.
