Abstract: A dehumidifier in the form of a circular or a multisides for intaking the wet air from at least three sides of the lower portion and blowing the dehumidified air out of only one direction of the upper portion to occur the convection circulating of the air flow to enhance the dehumidifying effect.
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 cleanable condensate trap usable with an air cooling system is disclosed. The condensate trap includes a U-shaped tube having first and second ends and a first T-shaped tube having first, second and third legs with the first leg being attached to the first end of the U-shaped tube. The second leg of the first T-shaped tube is connected to, for example, a drain tube which removes condensate from an air-handling portion of air cooling system. The third leg of the first T-shaped tube includes an opening whereby a cleaning device, such as brush, can be inserted into the U-shaped tube to remove material clogging the U-shaped tube. In order to detect a clogged condition of the U-shaped tube, the U-shaped tube can be made clear or transparent. Additionally, a switching device can be included in the third leg of the first T-shaped tube which can be operatively attached to a circuit which provides power to the air cooling system.

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: A freshener device for air for use in a refrigerator or freezer compartment for replacing an unwanted odor with a food or fruit-like scent. A process therefor is also provided. The device includes a perforated front plate and a perforated rear plate and a peripheral plate enclosing a chamber containing a selected particle mixture of about a 5 percent food or fruit extract, about 47 percent carbon filter type particles and about 48 percent sodium carbonate particles. The rear plate has a support and attachment means for mounting the device on an inner surface of a refrigerator or freezer wall and spaced therefrom.
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).
Abstract: An absorption refrigeration system having absorber and generator elements and a solution pump flowing relatively dilute refrigeration solution from a system absorber sub-atmospheric operating pressure to a system generator operating pressure is provided with novel low-pressure-differential, positive-displacement purge pump apparatus that is driven by bleed relatively dilute refrigeration solution taken from the solution pump high-pressure side, flowed through a coiled tube flow restrictor device to substantially reduce bleed solution operating pressure, and then through an inverted vertical U-tube that includes a V-shaped entrapment zone that receives un-wanted, non-condensed gases purged from the system absorber element.
