Abstract: A hydrogen production system for use in connection with Stirling engines. The production system generates hydrogen working gas and periodically supplies it to the Stirling engine as its working fluid in instances where loss of such working fluid occurs through usage through operation of the associated Stirling engine. The hydrogen gas may be generated by various techniques including electrolysis and stored by various means including the use of a metal hydride absorbing material. By controlling the temperature of the absorbing material, the stored hydrogen gas may be provided to the Stirling engine as needed.

Abstract: The present invention relates to a pulse tube refrigerator comprising a compressor for compressing operating gas while a piston performs a linear reciprocating motion inside of a cylinder by receiving the operating force of an operating motor installed inside of a housing, a after-cooler connected with the compressor, a regenerating unit connected with the after-cooler, a reservoir formed so as to be one-bodied to a pulse tube connected with the regenerating unit or a sealed casing or a housing, a vibration absorbing unit for reducing the vibration occurred by the operation of the operating motor by being fixedly combined to the sealed casing or a sealing member of the housing, the sealing member for improving the efficiency of the vibration absorbing unit combined between the housing and reservoir, and an inertance tube formed so as to surround the outer circumference of the pulse tube and reservoir in order to connect the pulse tube and reservoir. The pulse tube refrigerator in accordance with the present invention is capable of preventing an eccentric vibration of plate springs and a mass body about the axial directional vibration of the compressor by making the axial directional vibration in the operation of the compressor occur on the same line of the axial directional vibration of the plate springs and mass body of the vibration absorbing unit in order to absorb the vibration. Accordingly, the pulse tube refrigerator in accordance with the present invention is capable of improving the quietness of the operation by reducing the vibration noise of the overall system by stabilizing the vibration of the plate springs and mass body. In addition, the pulse tube refrigerator in accordance with the present invention can be transferred easily and requires the smaller installation area by reducing the overall size of the pulse tube refrigerator by placing the inertance tube at a proper position.

Abstract: The invention concerns a mechanism operating according to the principle which states that each point in a circle, running in the circle, describes a rectilinear hypocycloid. Said mechanism which is perfectly dynamically balanced reduces frictions to a minimum, and advantageously replaces conventional crank-rods, whereof the vibrations and frictions of the pistons pressing on the cylinders constitute major drawbacks. It can be used to produce rotary motors, capable of using any heat source, or any fuel, including hydrogen. It can also be used to produce refrigerating machines or heat pumps, using air as refrigerant, or machines for extracting water from air, using solar energy. Finally, it can be used for producing compressors, compressed air engines, hydraulic pups or engines, as well as vacuum cleaners, fans and nautical propellers.
