  • Patent number: 4849593
    Abstract: A heating element for retaining heat applied by reaction with high-frequency microwave radiation is provided in various forms. In one form, the heating element includes a multi-layered cartridge having a center core for dissipating heat, a layer of material reactive to microwave radiation for retaining heat and an outer layer of paper for substantially sealing the cartridge, yet permitting heat to radiate in use from the cartridge. In another form, the heating element has multiple layers formed of a rubber and cellular material for retaining water, the multiple layers being disposed about a central core of wax material. In a still further form, the heating element may comprise clay disposed within a covering, the clay containing minerals or aromatics, depending upon its use. In all such heating elements, the materials comprising the elements are reactive to high-frequency microwave radiation to retain heat and radiate such retained heat upon application for their intended purposes.

  • Patent number: 4022472
    Abstract: A target game including a target and one or more balls, which may be utilized to play a wide variety of different games, and the target of which is readily foldable into an essentially two-dimensional structure. The target, when made of foldable sheet material, includes four cutouts including a top cutout, bottom cutout, divider cutout, and support cutout. When the cutouts are assembled to construct the target, the target has closed back, bottom, top, and side walls, an open front, upper and lower chambers with portions of the target adapted to retain a ball bounced into one of the chambers in that chamber, a pocket formed on the front of the support, and side flap members converging inwardly toward the open front of the target. The target may also be constructed of fabric covered frame members.
