  • Patent number: 4190254
    Abstract: A game board for the play of partnership chess by four participants. The playing area of the board is 8-sided, being bounded by four straight sides alternated with four curved sides formed by quarter circles. A symmetrical checkered pattern of 120 four-sided and 8 five-sided playing spaces is provided on which four standard sets of 16 chess pieces are to be placed. In the preferred embodiment of this invention, an octagonal space or gate is located at the center of the board, with dotted lines establishing pairs of optional routes to either the right or left for those chess pieces permitted to make diagonal moves toward the board center.

  • Patent number: 4166572
    Abstract: A combined trash receptacle is proposed to be used on dining tables in public restaurants, or at home for the ready disposal of paper and plastic items provided for sanitary reasons, which would otherwise tend to clutter the table top in an unsightly manner. The trash receptacle is provided with one or more openings on the side thereof for the insertion and disposal of trash, and is moreover combined with either an accompanying ashtray, lamp stand, candle holder or flower vase, which in each case preferably serves additionally as the lid or cover for the trash receptacle.

  • Patent number: 4103130
    Abstract: A resistor assembly, together with a serially-connected resistor break, is connected in parallel, or shunting relationship, to an interrupting assembly, and arranged so that the resistor contacts remain closed while the main power-interrupting contacts open, and thereby divert the series line current through the resistor assemblage. This reduces the magnitude of the power-transmission line-current being interrupted, and lowers the rate of voltage rise across the main contacts so that arc reignition does not occur.During the closing operation of the circuit-breaker, the mechanical operating arrangement is such that the resistor contacts close prior to the closing of the main power interrupting contacts, so that any voltage surges occurring during the electrical charging of the transmission line are adequately controlled.
