Abstract: Gear bearings 1, 20, 30, 40, 50, 60, 70, 80, 90A and 90B, and 100 include gear, such as 9, and opposite facing tapered load bearing surfaces, such as 13 and 14. These gear bearings are positioned between, such as raceways 6 and 7 or 18 and 19, with bearing gears, such as 9 and 22, meshing with raceway gears, such as 10 and 21. The tapered surfaces preferably comprise the primary load bearing surfaces, with a line contact being maintained between the gear bearings and the raceways. The gears maintain proper registration of the gear bearings to prevent gathering. The same gear bearings can be employed in either linear bearing assemblies or rotary bearing assemblies. The gear bearings can be used in applications in which the defined position of the gear bearings can be used for control and monitoring moving parts or components, and the gear bearings can be used in devices, which transmit mechanical force.

Abstract: An internal combustion engine includes a slide body having a plurality of rigidly mounted pistons on opposite ends of the slide body. The slide body reciprocates and is connected to a flywheel by shaft and bearing which extends through an angled track in the slide body. As the pistons impart linear movement to the slide body, the flywheel and a drive shaft rotate. Both the slide body and the flywheel are mounted on the interior of the engine. Magnets on the flywheel rotate relative to stationary coil conductors to induce a current. The housing includes four panels, which can be easily assembled and disassembled, which form a housing compartment in which the linearly movable slide piston subassembly and the rotating flywheel are positioned.
