  • Patent number: 8082713
    Abstract: A screed corner comprises a screed base including substantially perpendicular nailing flanges and a bead leg extending away from each nailing flange. The bead has a horizontally disposed V-shaped cross section. A separate screed corner component is provided to be secured to arms of the bead and to close a gap in the screed base which is located in a volume comprising an intersection of a projection of each bead leg. The screed corner may be provided in a contour in sheet metal which can be readily bent to form a screed base. The screed corner component may comprise formed sheet metal. The corner component may comprise a sharp corner or may comprise a radius at its periphery. In one further form, the bead may comprise a substantially planar surface extending away from the nailing flange. In another, further form, the screed corner may be molded.

  • Patent number: 5819829
    Abstract: The present invention is a hood or cover for golf bags, which features pneumatic, air-filled tubes and/or stiffeners, used as a frame or skeleton, to produce a finite, yet compliant physical shape. The inventive rain hood utilizes a hinged top to accommodate the full range of club sizes and yet make removal and replacement quick, easy and positive. The hood or cover also shields the remaining clubs while removing or replacing any one club. A universal attachment system accommodates almost all golf bags commonly used today. The attachment mechanism is a one-step cinch system which is infinitely adjustable from the smallest to the largest of currently-used golf bags. Once attached, the rain hood inflates quickly to its rigid state with either a built-in hand pump or an auxiliary pressurized hand-held inflator.

  • Patent number: 5466286
    Abstract: A stable, air-dry, low-VOC waterborne metallic flake pigment dispersion containing an aqueous carrier, film-forming binder and metallic-flake pigment and having a solids content of about 10-30% by weight; wherein the metallic surface is passivated with a hydrophobically-modified aliphatic organic phosphate ester which is subsequently combined with an aqueous resin binder to stabilize the metallic flakes against long-term settling, gassing, floating, and reagglomeration of flake particles. The VOC of the resulting dispersion is about 2.5 to 3.5 lbs/gallon (minus water) and contains metallic flake pigments in a pigment-to-binder weight ratio of about 10/100 to 50/100. The dispersion can be used neat as a bright metallic waterborne base coating or combined with other colored dispersions and other compatible resinous materials.
