  • Publication number: 20080224023
    Abstract: An example concrete wall form assembly includes a frame having a plurality of studs. A first panel and a second panel fasten to the plurality of studs. The first panel and the second panel span the studs to provide a wall form that has a concrete receiving cavity having a cavity height. The wall form includes an aperture for moving concrete through the wall form to the concrete receiving cavity. The aperture has a first aperture height less than the concrete receiving cavity height.

  • Publication number: 20070210237
    Abstract: A concrete form panel has a plurality of studs. A first and second panel are fastened to the studs to define concrete receiving cavities between the first panel and the second panel. A fastening strip attaches the panels to the stud and is vertically oriented. In addition, a netting may span the studs. An opening extending from panel to panel may create a concrete-to-concrete interface between concrete in the form panel and a concrete footing. A column may be formed in this fashion. Moreover, ports, such as windows and door, may be provided in wall assembly. The assembly may be attached by a truss anchor to a truss for a roof.

  • Patent number: 6764732
    Abstract: A magnet receptive medium comprises a sheet having a first surface, a second surface, and an interior between the first surface and the second surface. At least one pathway between at least one of the surfaces and through the interior is formed. Magnetic particles of a predetermined size sufficient to pass through the pathways exist in such pathways. A binding agent may bind the particles to the interior.

  • Publication number: 20030152731
    Abstract: A magnet receptive surface covering comprises a nonferrous layer and a layer of ferromagnetic particles applied to the nonferrous layer. An adhesive layer is applied to the nonferrous layer. A cover sheet may cover the adhesive until the magnet receptive surface is to be applied to a surface, such as a wall.

  • Patent number: 6035991
    Abstract: An automatic transmission clutch plate provides reduced drag in a wet clutch environment by employing independent offset slots through a friction lining applied to an annular clutch plate. The slots extend through the friction lining from at least one inner or outer peripheral edge of the ring to a terminating point between the radially inner and outer edges. In addition, slots through the friction lining extending from the radially inner edge are offset from the grooves extending through the lining from the radially outer edge. Preferably, the friction lining is formed by segments, and slots can be conveniently formed through the lining between radial edges spaced apart from each other on adjacent arcuate lining segments. In addition, the arcuate segments preferably include overlapping ends to form the offset slots.

  • Patent number: 6019205
    Abstract: A method and apparatus for assembling a clutch plate includes forming arcuate segments from a friction material sheet, applying the arcuate segments to the ring in a fixed location with a temporary adherent, preferably to define intermediate spaces between the arcuate segments, and bonding the arcuate segments to the annular ring surface to form an automatic transmission clutch plate. Preferably, a set of multiple arcuate segments with independent edge boundaries are applied in a single workstation, and one or more sets may be applied to each annular surface by appropriately indexing the ring with respect to the application equipment. Preferably, the arcuate segments are formed by stamping the segments from sheets, the cuttings arranged at closely spaced positions on the sheet to reduce friction material waste.
