Abstract: A transparent container having a liquid therein, and dice in the liquid, of light weight and thus floating. The container also having therein an object of greater density than the liquid, thus constituting a sinking body. Upon reversing the container top-to-bottom, the dice float to the top and the body sinks to the bottom, wherein the dice and body move in opposite directions, have mutual engagement, or collide, effecting rotation or turning of the dice. When the dice reach the top of the container, the dice are read through the transparent top. In another embodiment, rods are mounted in the container, and extend toward the middle, which the dice engage, and the dice are thereby turned or tumbled. One form includes bars or pieces, instead of dice, with inscriptions thereon. In another form, balls are used and "fall" (rise) into holes in a roulette-type member.

Abstract: A shell having a closed upper end and an open lower end, and a weight in the form of a piston sealingly slidable in the shell. In one form partial vacuum is produced in the shell above the weight and atmospheric pressure consequently raises the weight. In another form, pressurized air lifts the weight, against the action of weight. The weight has driving connection with a load, such as a generator, and upon being permitted to drop, acting by its potential energy, drives the load. The partial vacuum is produced in one form, by heating and cooling units; and in another form, by natural heating and cooling. A plurality of power plants are utilized to drive a single load, so that one weight can be raised, and the power plant re-activated, while others continue to drive the load, thereby maintaining continuity of drive.

Abstract: In a grinder having a reciprocating table, a pair of oppositely arranged traverse potentiometers are actuated by the table, and in each direction, the respective potentiometer produces an increasing voltage to reverse the table. A pair of remote potentiometers are arranged respectively opposed to the traverse potentiometers, and are manually set to thereby determine the points of reversing of the table. Signal LED's indicate the position of the table, and these are controlled by signal potentiometer that is driven with the traverse potentiometers. Manual switch means enables the operator to selectively run the table past the normal points of reversal set by the remote potentiometers. Means is provided for slowing the speed of movement of the table at the end of its travel to minimize inertial shock.

Abstract: A pair of handles mounted individually on the ends of a coil spring, the ends of the coil spring extending longitudinally into the ends of the handles, and the coil spring thereby being positioned beyond the handles. A battery is positioned on one handle, and a light bulb and timer in the other handle. A circuit includes conductors, one of which is the coil spring, connecting the battery and the light bulb and timer, and contacts in the ends of the handles that are remote from the coil spring, and upon interengagement of the contacts they complete the circuit and turn on the light bulb and the timer. In squeezing the handles, in exercising the hand, illumination of the light signals the interengagement of the handles. The light bulb also illuminates the timer.
