Patent NL-7509067-A (NL)
Title: Heat pump or- engine with counter flow heat exchanger - has unequal compression and expansion cylinders out of phase to give constant pressure overflow
IPC: F01B29/08
Filed: 1975-07-30
Abstract: The unit can be used as a heat pump or a heat engine and comprises separate cylinders with different volumes for compression and expansion. Gas is compressed to a certain temperature and pressure at which point the overflow valves open. The gas thus enters the heat exchanger where heat is exchanged at constant pressure. The cranks give a phase difference between the compression and expansion piston such that the expansion piston is in top dead centre when the valves open, and the gas flows, via the heat exchanger, into the expansion cylinder at constant pressure. The difference between the cylinder volumes corresponds with the change in gas volume during heat exchange and is achieved by using different piston areas and equal stroke. This gives identical compression and expansion curves, whilst the mechanical power is proportional with the piston areas. The expanded gas goes back to the heat exchanger and returns to the compression cylinder to operate in a closed circuit.

Title: Power generator for ionic conduction lamp - provides power at high impedance during starting and power at lower impedance during operation of lamp
Inventor: SHERMAN ELI HENRY
IPC: H02M7/06
Filed: 1981-08-21
Abstract: The appts. generates power with a relatively high voltage and impedance so as to match the load before starting and generates power of a lower voltage and impedance so as to match the load during the energising and operation of the load. The appts. may have a coil, and a transistor, to develop a voltage over the coil. The coil may be coupled to the lamp through a capacitor or stray capacitance between the lamp and a coil. A tap intermediate the ends of the coil may be coupled to the load. The capacitor is effectively electrically inoperable and out of the circuit after starting of the load. The capacitor is located such that the full voltage developed across the coil is delivered to the load during starting, but after starting and during operation only a portion of the voltage developed between one terminal and the tap of the coil is used to drive the load. The generator eliminates the need of a conventional ballast and starting mechanism. In this way, the lamp can be maintained with energy savings. Further energy savings are achieved by generating current and voltage pulses for operating the lamp where the voltage pulses have a greater decay rate to a zero level than the current pulses which have a more gradual decay.
