  • Patent number: 5877437
    Abstract: Numerous products can be formed by combining a low melting matrix made up of one or more metals and high melting, high density metal particles and wherein the products can be formed by adding the high density particles to a molten matrix metal and casting same, mixing powders of all the metals together, compacting and sintering at a temperature in the low end of the melting range of the matrix alloy, or by mixing the high density particles into a paste of the matrix alloy and molding. These methods and compositions are particularly adaptable for use in forming low or non-toxic high density projectiles, such as, shot, bullets and pellets having a density comparable to that of lead while avoiding problems of toxicity associated with the use of lead.
    Type: Grant

  • Patent number: 4204701
    Abstract: Multiple attachment points for receiving universal adapters are retained by a relatively rigid structure in a generally rectangular orientation. The structure is rigidly attached to a structurally sturdy member such as the underframe of a vehicle. One arrangement of the attachment points employs four slots which are oriented at the effective corners of a rectangle and parallel to the anticipated direction of main tension loading. These slots are arranged to receive extension arms of a bracket-like adapter to which any of a wide variety of accessories can be mounted. For a vehicle, the slot-retaining frame can be rigidly secured to the underframe between the vehicle body and the protective bumper, attached to or included within a surface of the bumper or even mounted upon the flat bed surface of the vehicle body. In yet another arrangement of the mounting points, an arrangement of bars is rigidly secured to a box-like structure which is in turn secured to the vehicle body.
