摘要:
An apparatus for cryogenically freezing tissue specimens includes a linear motion platform and a pair of rotary motion platforms. The rotary motion platforms can be used alternatively with respect to the linear motion platform and a mechanism is provided to automatically trigger the linear motion platform for movement and to reset the linear motion platform when the rotary motion platforms are placed in covering relationship with or removed from covering relationship with respect to the linear motion platform. Cryogenic fluids are supplied to tissue receiving cryogenic discs on the various platforms through flexible plastic tubing. The tubing that supplies cryogenic fluid to the rotary motion platforms is constructed so as to form a series of loose loops in conjunction with tails that are mounted over a central rod to allow movement at cryogenic temperatures. The apparatus also includes elevation pylons for maintaining specimen receiving plates on the linear motion platform in a raised position prior to placement of the specimen in conjunction with the platform. Heaters and control systems are provided with respect to sets of the cryodiscs to allow an operator to select between using all of the discs or only groups of them.

An evaporative cooling device and method for removing heat energy from an object in thermally conductive contact with the device that is formed of a flexible and conformable container that is at least partially filled with a liquid absorbing material. When the device is hydrated and placed in thermally conductive contact with an object to be cooled, heat energy is transferred from the object to the device and the liquid that was absorbed by the material is evaporated. The amount of heat transferred is substantially equal to the latent heat of vaporization of the liquid that is evaporated. The use of the liquid absorbing material also allows the container to remain dry to the touch, even after it is hydrated.

A cooling apparatus for personal or general use is disclosed having interior and exterior surfaces and a fluid for dispersion by the exterior surface. The interior surface prevents the fluid from penetrating the interior surface and contacting the person or object to be cooled. The cooling apparatus may also include a fluid collector to collect excess cooling fluid, a device for moving the fluid from the fluid container to the fluid collector, and a return line for recycling at least a portion of the collected fluid. The exterior surface may be wetted by gravity seepage, capillary action, or the like. A band extending around each collector can aid in preventing the fluid from dripping from the apparatus.

The present invention pertains to a device for cooling testing tubes during sampling by evaporating a liquid. The cooling device causes a controlled cooling effect that is practically independent of the state of the ambient air during the sampling and is easy to handle. After flowing through the testing tube (2), the gas to be investigated flows through a layer of filler (7) that surrounds the testing tube (2) and is impregnated with a liquid.

Apparatus for automatically purging the primary reservoir in an evaporative cooler which utilizes a secondary reservoir supplied with a portion of the output flow of the recirculating pump. The primary and secondary reservoirs each contain drain valves actuated when the fluid level therein exceeds a predetermined level. The normal operating fluid level in the primary reservoir is established below the drain level. When the secondary reservoir is filled and drains, its flow is directed into the primary reservoir causing it to exceed its fluid drain level and thus automatically purge the primary reservoir of fluid.

An evaporative self-chilling dispensing container for potable liquids has a wall of porous material immersible in a coolant fluid defining an inner wall surface, an outer wall surface, and a generally transverse lip surface joining the inner and outer surfaces. The inner wall surface defines a cavity for receiving a potable liquid and a mouth opening rimmed by the lip surface. A thin impermeable layer fully lines the interior wall surface and extends uninterruptedly outwardly over the lip surface to prevent intermixing of the coolant fluid with the potable liquid during storage and also while said potable liquid is poured from the container.

THIS DISCLOSURE RELATES TO A ROOF TOP EVAPORATIVE COOLER FOR COOLING THE INTERIOR OF VEHICLES SUCH AS CAMPERS AND TRAILERS, WHETHER THE VEHICLE IS MOVING OR STATIONARY. THE UNIT INCLUDES A REAR FACING STREAMLINED HOUSING DISPOSED OVER A ROOF TOP REGISTER, WITH A WIND DEFLECTOR SUCH AS A SPOILER FOR DIRECTING THE AIR STREAM PASSING OVER THE UNIT INTO A LOUVERED ENTRANCE PORT. A SUCTION FAN IS DISPOSED WITHIN THE HOUSING BETWEEN THE ENTRANCE PORT AND THE REGISTER FOR PULLING AIR INTO THE HOUSING, THROUGH AN EVAPORATIVE PAD AND FOR EXPELLING THE COOLED AIR, GUIDED BY THE CONFIGURATION OF THE HOUSING, THROUGH THE REGISTER AND INTO THE VEHICLE. THE COOLING MEDIUM IS PUMPED FROM A SUPPLY TANK TO A DISTRIBUTOR OVER THE PAD AND COLLECTED AFTER IT PASSES THROUGH THE PAD FOR RECIRCULATION. THE SUPPLY TANK MAY BE EITHER INCORPORATED WITHIN THE COOLER HOUSING OR EXTERNALLY DISPOSED THERETO AND MOUNTED ON THE VEHICLE BODY. THE PAD IS CONSTRUCTED FROM A SUITABLE POROUS MATERIAL AND THE COOLING MEDIUM IS TYPICALLY WATER.

A COOLER IN WHICH FLUID MAY BE COOLED, AND FROM WHICH FLUID MAY BE DISPENSED BY OPERATION OF A DISPENSER ASSOCIATED WITH THE FUEL INTAKE OF A GASOLINE ENGINE IN A CAR, TRUCK, BOAT OR OTHER VEHICLE. THE COOLER INCLUDES A GASOLINE VAPORIZER IN A CONTAINER HAVING A PARTITION, PREFERABLY A CUP, AT LEAST PARTLY ENCLOSING THE VAPORIZER. THE VAPORIZER INCLUDES A FIRST TUBE AND A SECOND TUBE, PREFERABLY COILED, WITH THE SECOND TUBE BEING LOCATED INSIDE THE FIRST TUBE. PREFERABLY, THERE ARE: (1) A FLUID INLET LEADING FROM THE CONTAINER INTO THE PARTITIONING CUP, (2) A GASOLINE INLET LEADING INTO THE SECOND TUBE, (3) AN AIR INLET LEADING INTO THE FIRST TUBE TO SUPPLY AIR TO AN AREA THEREIN WHERE GASOLINE IS VAPORIZED, (4) AN EXHAUST OUTLET FOR THE FIRST TUBE TO DRAW A GASOLINE-AIR MIXTURE THROUGH THE FIRST TUBE OVER THE SECOND TUBE FOR COOLING PURPOSES, AND (5) A FLUID OUTLET FOR SUPPLYING COOLED FLUID FROM THE CUP TO THE DISPENSER. THUS, FLUID MAY BE STORED IN THE CONTAINER, COOLED IN THE PARTITIONING CUP OR SHELL, AND DISPENSED FROM THE SHELL.
摘要:
A drinking glass froster is provided which enables a glass, such as a cocktail or champagne glass, to be frosted both internally and externally, to thereby retain the glass in its cold condition for longer periods. The froster is of extremely compact construction and design, and is characterized by the fact that it can be quickly and easily assembled and disassembled, with all parts readily accessible for repair or replacement purposes. It is designed especially for use in conjunction with small tanks of liquid carbon dioxide.
