Patent number: 7081221Abstract: An article of textile-soled footwear and method of making employ a simple fabrication process and apparatus that allows fabrication of the footwear outer shell via a single injection-molding step. The article of footwear has a textile layer at the ground-contacting surface of the outsole, the textile layer being moldably and integrally attached, in a common mold, to the molded outsole as it is being created during the injection process. Fasteners are set along the side of the sole plate of the injection mold to secure the textile layer across the sole plate and prevent it from being moved during injection of the moldable compound to form the outsole. The sole plate and the sidewalls of the injection mold are assembled in place for the injection process. The shoe upper is fitted onto the shoe last and set in place in the mold, the mold is closed, and the moldable compound is injected into the mold.Type: GrantFiled: April 14, 2003Date of Patent: July 25, 2006Inventors: Stephen L. Paratore, Bilo Tsui

Patent number: 7040884Abstract: A system for manufacturing foamed plastics laminated panels at a high volume is disclosed. Press modules include a pair of opposed spaced open frame members with longitudinal raised sections attached to perpendicular supports. The open frame members move relative to one another, support respective panel outer skin layers; and recieve therebetween edge sealing members of a predetermined thickness. A spacing between the open frame members and a hinge is adjustable to move a first open frame member relative to a second frame member. Clamps retain the open frame members in a predetermined space relationship, and when actuated, forms a mould cavity defined by the outer skin layers and edge sealing members supported by the open frame members. An inlet introduces an a liquid foamable plastics material into the moulded cavity, and a delivery system delivers liquid reactants in predetermined proportions to a selected mould cavity formed in a selected press module.Type: GrantFiled: January 31, 2003Date of Patent: May 9, 2006Assignee: Euretech International Pty Ltd.Inventor: Tonny Bergqvist

Patent number: 7025844Abstract: An improved process for permanently attaching an overlay to a wheel disc, wherein the overlay is aligned and spaced apart from the wheel disc. A mold is created by a combination of the overlay, wheel disc and localized nests that engage at predetermined times during foam filling to close the mold. The mold is adequately sealed so that there is no foam leakage as the foam expands to fill the mold and, therefore, no final trimming of excess foam is required. The improved process is capable of accommodating a wheel having turbine openings therein.Type: GrantFiled: May 14, 2001Date of Patent: April 11, 2006Assignee: Lacks Industries, Inc.Inventors: Lee A. Chase, Douglas Louis Neeb, Robert E. Shea

Patent number: 7018480Abstract: There is disclosed a method of forming a fabric 1 on the surface of a mandrel 10, infiltrating the formed fabric with matrix, and leaving portions 12a, 12b of the mandrel as integral with the fabric and removing the mandrel before the fabric adheres to the mandrel by matrix infiltration. Subsequently, a remaining portion of the mandrel is used as a reference surface and machining is performed. Without possibility of adhesion to the mandrel and resulting breakage, machining bases (axial center and reference surface) during machining can accurately be provided, and this can largely enhance machining precision and yield of a final product.Type: GrantFiled: March 7, 2003Date of Patent: March 28, 2006Assignee: Ishikawajima-Harima Heavy Industries Co., Ltd.Inventor: Takeshi Nakamura

Patent number: 6899535Abstract: The present invention provides an apparatus for forming concrete structures, such as railroad crossing signal foundations. The apparatus includes a generally hollow form, which is made from a strong and durable material, such as metal (e.g., steel) or composite material. The form is tapered and includes two halves that are selectively attached together for easy removal from a completed foundation. The form further includes several cantilever bolt holders that extend over the form and include holes that receive cantilever bolts that are incorporated into the foundation. One or more vibrating elements may be removably attached to the tops of the cantilever bolts and/or to the sides of the form. The air vibrators may be selectively activated during the cement pouring process to vibrate the concrete and substantially reduce or eliminate air bubbles and defects within the foundation. A pair of adjustable legs is attached to the form and allows the form to be positioned and supported over a foundation hole.Type: GrantFiled: May 30, 2003Date of Patent: May 31, 2005Inventors: Pete Mihelcic, Daniel M.
