Abstract: The invention relates to an apparatus that includes a first heat exchanger for heating a first heat transfer medium in a first form from a first temperature to a second higher temperature to provide an increased pressure gas, a first mechanical device configured to use the increased pressure gas to provide mechanical energy to one or more primary components, and one or more additional mechanical devices configured to use the increased pressure gas to provide mechanical energy to one or more secondary components. The mechanical device produces spent gas, and a conversion device is operably associated with at least one of the mechanical devices to convert the spent gas to the first form for re-use.

Abstract: A fuel injector cleaning kit includes a pressurized container containing a pressurized mixture of a fuel injector cleaning fluid and a motor vehicle fuel. The kit includes instructions, hoses and adapters for connection to a plurality of different motor vehicles. An adjustable pressure regulator, included as part of the kit, controls the pressure of the mixture delivered to the vehicle to a value specific to the particular vehicle.

Abstract: A meter reader assembly is adapted for mounting on a standard utility meter having a plurality of rotating dial elements for visually indicating total units of the utility consumed. The assembly includes a magnetic reed switch fixedly mounted adjacent the single meter dial element which indicates the lowest whole unit of utility volume consumed, and one or more permanent magnets mounted on this single dial element in a position to traverse the reed switch each time the single dial element rotates through a distance to indicate the consumption of a single whole unit of utility. The reed switch opens and closes each time it is traversed by a magnet to produce an electrical pulse in a logic circuit which also contains a summing circuit for totalling the pulses, and a shift register memory.

Abstract: An intermittent pulsing ignition system for gas fired devices includes a pulser assembly having a predetermined on/off cycle, providing full wave alternating current during the on cycle and half wave current during the off cycle, to an electrical ignition element. The full wave current is sufficient to heat the ignition element to the ignition temperature of the gas and the half wave current permits the ignition element to cool during the off cycle thereby prolonging its useful life.
