  • Patent number: 6323652
    Abstract: An electrical testing device for determining the continuity between ground terminals of an electrical power cord and determining the electrical grounding of an electrical power tool. The electrical testing device can also be configured to determine the proper polarity on each of the hot, negative, and ground cord wires of an electrical power extension cord. The electrical testing device includes a plastic case housing one or more batteries which supply power to a test button and the ground terminal of a female receptacle installed in the case. The top surface of the case includes a female receptacle, a test button, and a ground light. The top surface may also include a male plug and an additional female receptacle installed in the case. On the side of the case is an extending metal contact element. The test button is a single pole momentary contact test button.

  • Patent number: 3995600
    Abstract: A rotary piston internal-combustion engine adapted to operate on a hydrogen fuel gas mixture injected into the intake chamber of the engine through a plurality of spaced intake ports in the engine housing designed to distribute the flow of the fuel gas mixture evenly along the width of the intake chamber. The exhaust gas outlet of the engine includes a plurality of spaced small exhaust ports so as to decrease the dwell of the apex seal of the rotary piston as it passes over the exhaust gas outlet. The fuel supply system to the engine includes a plurality of mixing chambers to ensure thorough and uniform mixing of the fuel gas mixture, an intake header for distributing the fuel gas mixture to the intake ports, and means for preventing back-fire of the fuel gas mixture in the system. Lubricant may be supplied to the interior of the engine through the fuel intake ports in the form of a lubricating vapor in admixture with the fuel gas mixture.
