Abstract: The present invention concerns an on-vehicle air-conditioner, resolving problems of the prior art, and allowing to perform cooling, heating, dehumidification or others efficiently even for vehicles of low waste heat, such as hybrid cars taking electricity and gasoline as energy source, idle stop coping cars or battery cars taking only electricity as energy source, or other vehicles, by cooling by loading a refrigeration circuit, using for example CO2 refrigerant, and provided with an electrically driven two-stage compression system compressor, and at the same time, installing a refrigerant heat exchanger for cooling the refrigerant, compressed in the first stage in a way to exchange heat with the car interior air, and using conveniently also for heating together with the heat of the cooling water for cooling the engine.

Abstract: An arrangement for preventing the development of a frozen bond between individual pieces of cubed or crushed ice collected in a storage bin. The arrangement includes an upstanding flexible wall lining a majority of the inwardly facing wall surface of a storage bin. An agitator device is provided for moving the pieces of ice about within the confines defined by the flexible wall. The agitator includes a rotatable shaft, an arm secured to the rotatable shaft and extending radially thereof and a drive arrangement for drivingly rotating the shaft. Structure is provided for effecting a flexing of the flexible wall toward and away from the inwardly facing walls of the storage bin. The agitator device and the additional structure causing a flexing of the flexible wall periodically initiates a movement of the individual pieces of ice to thereby prevent the development of a frozen bond between the individual pieces of ice.

Abstract: An improved hot water heating system used with an internal combustion engine is disclosed. This system provides a hot water flow control arrangement in which hot water supplied to a heating radiator is controlled by a valve and a pressure responsive bypassing means to keep a comfortable temperature. The pressure responsive bypassing means is closed when the maximum heating capacity is required to avail to the heating radiator all the hot water supplied by the engine even when the hot water pressure increases to exceed a bypassing pressure level.
