Abstract: A hypocycloid reducing apparatus includes a hollow outside bracket, a hollow inside bracket and a driven input that is rotated by a rotating mechanism, such as a motor. The outside bracket has a passage with N quantity of lobe grooves. The inside is rotatably mounted in the passage of the outside bracket and has an inner space, M quantity of through holes and an output shaft. The through holes are arranged in an annular arrangement, are aligned with the lobe grooves and each through hole holds a roller. The driven input is mounted rotatably in the inner space and has an off-center assembly to encounter sequentially with each roller to actuate rotating the inside bracket. Therefore, a speed of revolution of the rotating mechanism is reduced to the output shaft. A volume of the reducing apparatus is minimized, as is noise produced during operation.

Abstract: An electrolytic fueling system for engine comprises generally a water tank, an electrolyte, a segregator, an acetone container, an automatic air valve, a pressure control device and a multi-point antibackfire device connected by a number of conduits or passage thereinbetween for producing dried and purified gas of hydrogen and oxygen to run a generic combustion engine. The improvement of this disclosure is characterized in adapting a plurality of cup shaped water absorbing sintered alloy blocks which are of different size and sequentially nested in the electrolyte and interlocked with the anodes and cathodes of the power source. The electrolyte in which the blocks immerse is a mixture of fresh water and potassium hydroxide (KOH) in predetermined proportion.

Abstract: An automobile air conditioning system comprises generally a regenerator, a segregator, a condenser, an evaporator, an absorber, a heat exchanger and a plurality of conduits intercommunicated therein between to form a circulation system producing cooled air. The improvement of this disclosure is characterized with the adaptation of a coil tube wound around the outer periphery of an exhaust pipe and utilizing the residual heat of the waste gas expelled from the engine to vaporize the liquidized refrigerant NH, instead of a compressor. In addition a tubular network is provided to utilize the heat from the sun which is collected on roof and bonnet panels, to strengthen the capability of cooled air production. This invention would release the load of a compressor from the engine and achieve a savings of energy.
