20110221208 | Opposed piston electromagnetic engine - A converter converts mechanical energy of a piston to and from electrical energy during each piston cycle. | 2011-09-15 |
20110221209 | Buoyancy Energy Cell - A device for the generation of energy and in particular electrical energy includes a cell or chamber which moves upwardly and downwardly in a body of water. Cog wheels are connected to the cell. The cog wheels are connected to the shafts of generators. Rotation of the cog wheels operates the generators which produce energy. The cog wheels engage anchor chains or vertical supports. The up and down movement of the cell causes the cog wheels to move upwardly and downwardly along the anchor chains and thereby rotate. This rotation drives the energy generator and generates energy, preferably electricity. The cog wheels are permitted to rotate upon the receipt of a request for energy. This results in a highly efficient source of energy or electricity. Energy from other sources, such as wind or tides, can be utilized to operate the cell. | 2011-09-15 |
20110221210 | ENGINE STARTING SYSTEM WITH HIGH-AND LOW-SPEED MODES OF MOTOR OPERATION - An engine starting apparatus includes a first and a second power supply path extending from a battery to an electric motor to start an engine.

A motor relay has relay contacts disposed in series with the resistor. A controller delays the time when the main contacts are closed to apply a full voltage of the battery to the motor until a given time lag has elapsed after the relay contacts are closed to supply electric current to the electric motor through the resistor. Specifically, when it is required to apply the full voltage to the motor to run the motor at a rated speed, the current does not pass through the relay contacts, thus resulting in no voltage drop, which ensures the stability in starting the engine. | 2011-09-15 |
