Abstract: A heat exchange system for a supersonic flight vehicle. A first conduit connects the gas (e.g., helium) exit of a compressor of a gas-driven turbocompressor to the gas inlet of a turbine of the turbocompressor, and a second conduit connects the gas outlet to the turbine to the gas entrance of the compressor. The first conduit has a portion positioned near a hotter temperature region (e.g., the combustor wall) and the second conduit has a portion positioned near a colder temperature region (e.g., the fuel region) of the flight vehicle. The temperature difference self powers the turbocompressor which can transfer large amounts of heat and which is hermetically-sealed in a housing against gas leaks.

Abstract: A cooling vessel for beverages that has an inner wall surrounded by an outer wall that is spaced therefrom to form a chamber that is filled with a refrigerant. The refrigerant functions to insulate the interior of the vessel from its outer walls, thus keeping its contents cold and keeping condensation off the outer surface of the vessel. The cooling vessel may be made of heavy plastic material that makes it unbreakable even after quick temperature changes. The cooling vessel may be designed to have the outer configuration of a mug, a glass, a pitcher, a baby bottle, etc.

Abstract: An artificial snowfall system comprises a snowfall room (2) in which are properly disposed a snow catching element (4) made of materials excellent in gas permeability and an atomizer unit (8) for ejecting atomized particles of liquid into the room (2). The atomized particles are frozen by heat exchange with ambient air within the room (2). The ambient air is kept at a temperature of below a freezing point of the liquid and forms an air flow passing through the snow catching element (4). The air flow causes the frozen particles to be deposited on one side of the catching element (4) to form a snow layer thereon. A beater element (9) for beating the other side of the catching element (4) is oppositely disposed from the other side to have the snow layer separated from the catching element (4). The thus separated snow layer creates artificial snowfall in the room (2).
