  • Patent number: 7037461
    Abstract: A method of stretching films in which all or a portion of the width of the film is cooled during or just after stretching so as to improve the uniformity of the film. The includes stretching a polymeric film in a tenter that grasps the film with a plurality of clips along the opposing edges of the film and propels the clips to thereby stretch the film. The tenter includes driven clips and idler clips, with at least one idler clip between respective pairs of driven clips. The cooling is done so as to improve the uniformity of the clip spacing relative to the spacing obtained at otherwise identical process conditions without such cooling.

  • Patent number: 7025923
    Abstract: A thin-walled polymeric component that may have a selected complex shape, and a method of forming the component. The method includes heating a portion of a polymeric film to a selected malleable temperature, and forming a protrusion in the heated portion while it is malleable. The protrusion defines a protrusion having a first shape. The method also includes positioning a forming tool in the protrusion's interior and drawing a partial vacuum from within the protrusion so as to exert a force on the protrusion and move the protrusion's sidewalls inwardly into engagement with the forming tool. As the partial vacuum is drawn, the protrusion moves to a second shape that may be different than the first shape and that closely conforms to the selected shape of the forming tool. The protrusion is cooled below the malleable temperature and the forming tool is then removed.

  • Patent number: 7018577
    Abstract: A method of forming a liner for a passage such as a sewer includes forming panels composing the liner using a neat resin of a first density and a polymer concrete of a second, higher density. The neat resin is inserted into a mold cavity before the polymer concrete and is displaced upwardly by the polymer concrete pour to impregnate a fiber layer disposed along the periphery of the mold cavity. Resulting panels preferably have an offset joint to increase the joint strength between upper and lower panels forming the liner.

  • Patent number: 6936211
    Abstract: Methods for making a tubular device that has a rim disposed at one end thereof. In one method, a sleeve having an expandable profiling surface is inserted into an end of the tubular member, and the profiling surface is expanded to form a shoulder projecting outwardly from the tubular member adjacent the end of the tubular member. The profiling surface is collapsed inwardly away from tubular member, and a return margin is formed directed inwardly from the shoulder, distal the tubular member. In another method, return margin of the tubular device adjacent an end is folded inwardly and superposed on an inner surface of the tubular device adjacent the folded margin. A sleeve having an expandable profiling surface is inserted into the end of the tubular device, and the profiling surface is expanded to form the rim comprising a shoulder projecting outwardly from the tubular member and the return margin. As a result, the fold between the shoulder and the return margin defines an edge of the tubular member.

  • Patent number: 6916438
    Abstract: The texturing, patterning and bending of a solid surface material. The end product can be achieved both through casting technologies and heat pressure processes. Controlled surface deformation can be created in a pre-manufactured flat sheet and the sheet can then be heated and bent using conventional thermoforming technology. This contrasts considerably with the conventional norm, whereby an embossed solid surface sheet, when reheated, loses its embossing.

  • Patent number: 6911165
    Abstract: A method is provided for fabricating a concrete slab in a substantially horizontal slip casting process method, concrete mix is fed into a mold through a delimited cross section moving progressively in the casting process so as to form a concrete product of a desired shape. Onto the surface of the casting bed (1) is placed a core (3, 9, 10, 11) capable of delimiting the cross section of the concrete product (5, 5?) so as to provide an opening or a provision for an opening in the bottom surface of the slab. A core is provided for obtaining an opening or a provision for an opening. The structure and/or material of the core is/are such that the core is capable of yielding in vertical direction. A core may also be a multipart core, the outer part of which becomes detached from the inner part of the core in conjunction with lifting off the concrete slab from the casting bed.

  • Patent number: 6905647
    Abstract: Golf ball 1 includes a core 2 and a cover 3. The core 2 has two layers including a center 4 and a mid layer 5. The mid layer 5 is formed by covering the center 4 with two half shells comprising a rubber composition, and by compression and heating of the center 4 and half shells in a mold. The rubber composition contains solid particles dispersed therein. The solid particles have a ratio “D/T”, i.e., a ratio of the particle size D to the thickness of the mid layer T, of equal to or greater than 0.3. Upon molding, the solid particles inhibit the center 4 to approach a cavity face. Accordingly, deviation of mass of the mid layer 5 can be suppressed. The solid particles have a ratio “W/T”, i.e., a ratio of the radial width W thereof to the thickness of the mid layer T, of from 0.3 to 1.0.
