    • A pump is provided featuring a housing and battery configuration, where the housing is configured with a battery receiving portion having electrical terminals for receiving power to the pump, and where the battery has a protruding portion with corresponding electrical terminals configured to contact the electrical terminals to provide power to the pump when the protruding portion of the battery is inserted into the battery receiving portion of the housing and rotated in one direction to an “ON” position, and also configured not to contact the electrical terminals when the battery is not rotated to the “ON” position.
    • 提供具有壳体和电池配置的泵,其中壳体配置有具有用于向泵接收电力的电端子的电池接收部分,并且其中电池具有突出部分,其中相应的电端子被配置为接触电端子到 当电池的突出部分插入壳体的电池接收部分并沿一个方向旋转到“ON”位置时,向泵供电,并且还构造为当电池未旋转时不接触电端子 “开”位置。

    • A game ball is comprised of an outer layer of foamed polyurethane plastic having a density of approximately 15 pounds per cubic foot, the layer having an external integral skin having a density of 20-30 pounds per cubic foot providing a protective cover and an integral inner skin having a density of 20-30 pounds per cubic foot providing a cavity in which a core ball of resilient material is contained. The core ball has a density of 70-76 pounds per cubic foot and a lesser degree of compressibility than the foamed layer of polyurethane plastic. The core ball is lubricated by carbon contained in the core ball when fabricated from natural rubber and by means of a lubricating film when fabricated from natural rubber and polybutadiene so that in either case the core ball is free to move or shift within the cavity when the baseball is impacted by a bat.
