  • Patent number: 5064896
    Abstract: Heat curable adhesive compositions which include liquid polybutadiene polymer, powdered sulfur, organic accelerators and inert fillers are improved by adding blocked polyisocyanates or capped polyisocyanates. The addition improves resistance to "popping" of the cured or uncured adhesive when exposed to high temperature, e.g., spot-welding. The addition does not alter the beneficial flow properties and rheological properties of the adhesive. The adhesive is particularly useful on zinc coated steel, both electroplated zinc and hot-dip galvanized zinc coatings. Inclusion of zinc borate will activate the cure accelerators and retard the "popping" phenomenon at welding temperature.

    Abstract: The surface of a basketball is provided with rows of pebbles or projections, each of which has a flat triangular outer surface and three pointed apexes.

  • Patent number: 4568081
    Abstract: A self-lubricating plug insert-type valve assembly is provided for use with inflatable articles of manufacture, such as footballs, basketballs, etc. The sealing plug through which the inflation needle is inserted is characterized by containing 3-12 parts by weight of a silicone grease for each 100 parts of rubber contained therein. Although contained as part of the rubber mix of the cured plug, the grease migrates within the plug and forms a continually renewed lubricant coating along the passage through which the needle is inserted and withdrawn.
