Abstract: An air cycle water producing machine utilizes a combination of cooling turbine, heat exchanger and fresh air cycling to increase water output while minimizing the amount of energy required to operate the system.

Abstract: An air cycle air conditioning system is provided that utilizes the compartment to be cooled as a heat storage chamber within the system. In an automobile environment, the use of the enclosed passenger compartment as a heat storage chamber within the air cycle system enables the construction and implementation of a compact low energy consumption air conditioning system within the automobile. Through the use of valves within the system, the air cycle air conditioner is easily converted into a heat pump for the passenger compartment. The system of the present invention can be implemented in industrial, commercial, residential and/or automobile applications.

Abstract: The method and apparatus for cryogenically freezing materials, such as rubber, food, plastics which provides a first air compressor for compressing the ambient air to between 5 and 6 atmospheres, a means for cooling the air back to an ambient temperature, a second compressor system for compressing the air to between 10 to 12 atmospheres, a second cooling system for cooling the air in two stages to 40° F., means for removing carbon dioxide and water moisture from the air following each of its compression and cooling stages, and an expansion turbine for allowing the compressed air to expand and cool to cryogenic temperatures that is fed to the material to be processed. A feedback loop having a valve is also provided so that a portion of the cooled and dried compressed air is fed back through a heat exchanger to the input of the first compressor after the cooled material has been stabilized in order to control the output temperature of the apparatus.

Abstract: A magnetic separator having a chamber for receiving material to be separated. The magnetic separator utilizes magnets either along the outer surface of an elongated cylindrical chamber or as a fixed shaft of a helical conveyor. Two outputs are provided for discharging the non-magnetic material and the magnetic material separately from each other.

Abstract: The invention relates to process for recycling tires and other recyclable materials. The process includes a series of steps designed to reduce a rubber or polymer tire into pulverized material. The process involves first shredding the tires or recyclable material into chips. The chips are then cooled to cryogenic temperatures at which said pieces become brittle. The brittle pieces are then pulverized in the second step. Pulverized material is then screened, removing large chunks of rubber or polymer from the mixture. Finally, the remaining fiber and magnetic material is separated out of the pulverized material, through the use of a magnetic separator and a vibrational (fiber) separator.

Abstract: There is provided a cooling device for lowering the temperature of rubber or polystyrene materials for recycling purposes. The cooling device has an input feeder which inputs the material to be treated into a cooling chamber. The cooling chamber is an elongated chamber. The cooling chamber receives cold air from an external air refrigeration unit and circulates that air within the chamber. The material input into the cooling chamber is circulated therein by a circulating shaft. After 15-20 minutes, the input material is discharged through an output on the opposite end of the cooling chamber. The temperature of the material discharged is -80.degree. C. or lower.
