Abstract: A process for conditioning a gas containing the vapors of a volatile substance, in which the gas is placed sequentially in contact with successively more concentrated solutions of an absorption liquid on cooled surfaces, such absorption liquid consisting of a solution of said volatile substance and at least one non-volatile substance. The vapors in the gas are isothermally absorbed into the absorption liquid upon such contact, thereby diluting the concentration of the absorption liquid. The diluted absorption liquid is concentrated by multi-stage evaporation in a multi-stage evaporator. The concentrated absorption liquid is recycled back to the cooled surfaces.

Said humidifier may be located on the outlet side of cooled air supplied form a cooling coil of a display case to avoid inconvenience that humidified air might be brought into direct contact with the cooling coil and condensated, with loss of humidified steam.

Abstract: A cell preservation system utilizes a pre-chilled coolant stored in a coolant reservoir, which is pumped at a controlled rate into a specimen vessel containing a specimen. This allows the achievement of a controlled rate of cooling the specimen and controls the formation of crystals in the specimen. The coolant reservoir is sealed, and the coolant is pumped from the specimen vessel to the coolant reservoir, whereby heat from the pump is not entered into the specimen vessel. A magnetic stirrer is selectively controlled to maintain a uniform temperature in the specimen vessel or, alternatively, is deenergized to permit temperature stratification to occur. A heater is included in the specimen vessel for precise heat control, and for raising the temperature of the coolant in the specimen vessel to a value suitable for beginning a cooling cycle.

Abstract: The invention relates to a method of and an apparatus for reducing the stickiness or tackiness of the fibers of honeydew-contaminated cotton flocks by heating the same. For this purpose, the cotton flocks while still in bale form are heated in a high-frequency electrical or electromagnetic field until the honeydew is brought to an elevated temperature and the water contained in the honeydew contamination is substantially evaporated, the temperature preferably being such that the cotton flocks reach a temperature in the region of the temperature of ebullition or boiling point of water.

Abstract: A beverage cooler and dispenser wherein bottled beverages are received into a housing member and the beverage therein is transferred by gravity to a cooling chamber comprising honeycombed beverage passageways. The beverage is thermoelectrically cooled within the honeycombed passageways and selectively dispensed from the cooling chamber via a spigot fixedly attached to said housing member.

Abstract: A heat exchanger as provided in which an outdoor coil circulates a heat-exchange medium therethrough and includes a conventional upper inlet and lower outlet for respectively receiving and discharging the heat-exchange medium. A fan draws ambient air through the outdoor coil during the heating phase of the heat exchanger, and a gas flame generates heat to further increase the temperature of the heat-exchange medium beyond that created by the heat-absorbed from ambient air. A control system is provided for at least at times simultaneously operating the fan and the gas flame. The control system also at times bypasses the outdoor coil at extremely low ambient temperatures.

Abstract: Disclosed is a self-contained, rapid cooling device that can be stored for indefinite periods without losing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber. A sorbent in a second chamber is in fluid communication with the vapor and removes the vapor from the first chamber. A heat sink material thermally coupled to the sorbent collects and irreversibly captures heat transferred from the vapor to the sorbent.

Abstract: The structure of the present invention comprises a self-cooling container in which a segregating wall is used to divide the container into a beverage chamber and a cooling chamber, the latter having a reaction chamber mounted therein, which in a preferred embodiment is of an elongated cylindrical shape. The reaction chamber cylinder of the present invention provides an inverted funnel-shaped bottom surface for receiving the flow of beverage from the beverage chamber portion of the container through a feed-through at the bottom of the segregating wall thereof. The funnel leads to a flow tube which is positioned in axial alignment with the cylinder, preferably through the center thereof and defining an inner wall of the reaction chamber. The reaction chamber houses a combination of chemical materials separated by a readily broken sealing device from a selected volume of distilled water, which rfeleased into the chemical constituents, initiates an endothermic reaction which extracts heat from the beverage.
