Abstract: A kitchen utensil molded of rubber or flexible synthetic plastic which has a centrally disposed, stepped, hollow frustro-conical jar cap remover that is readily gripped in the palm of the hand, surrounded by a radially disposed, planar flange, the surface of which on the side of the hollow is roughened or otherwise formed for soft abrasive action. The stepped frusto-conical portion can receive different size jar caps and has axially disposed ribs on the cylindrical walls of the step portions for frictionally engaging the rim of a jar cap to facilitate its removal. The frustro-conical portions are capable of nesting with each other in spaced relation so that a plurality of the devices may be gripped and handled simultaneously. In this manner, the utensil may be used as a pot holder with the conical portions preventing slippage between a plurality of the devices and also providing air spaces between the devices for insulating purposes.

Abstract: A plurality of individual batteries are independently mounted for reciprocatory movement according to the motion of a supporting vehicle, and means are actuated by the reciprocal movement of the batteries for converting such movement to constant rotary movement to drive means for regenerating said batteries. The batteries are disposed in spaced relation to facilitate cooling.
