  • Patent number: 9915450
    Abstract: A multi-split air or ground source heat pump system designed to provide a residential application with space heating and cooling, along with supplemental hydronic heating and potable water preheating. The supplemental hydronic heating supports applications like radiant floor heating and heating swimming pools. Commercially, the multi-split air or ground source heat pump system expands on this technology to incorporate comfort and/or process heating, cooling, and hydronic heating applications utilizing multiple types of energy sources.

  • Patent number: 5284267
    Abstract: A fuel injection apparatus for a vehicle includes a throttle body having an air flow passage extending therethrough with a throttle plate mounted in the passage. At least one fuel injector is mounted below the throttle plate and above the intake manifold of the engine for cyclically injecting fuel into the air flow passage extending between the throttle body and the inlet of the intake manifold. A full time, closed loop feedback control system monitors exhaust gas content and adjusts the fuel flow based on the measured air/fuel ratio. A tank storing gaseous fuel at a high pressure is connected to the fuel injector via fluid flow conduits. An annular recess is formed on at least one location on the side wall of the tank. Annular shoulders are disposed on opposite sides of the recess and extend outward above the side wall of the tank. A mounting bracket is mounted in the recess surrounding the tank and is attachable to the vehicle to mount the tank to the vehicle.
