A cooling agent which cools by an endothermic reaction resulting from the dissolving of crystals of inorganic salts water, the salts crystallizing at about room temperature by supplying heat. The cooling agent comprises a mixture of (i) a sodium phosphate salt, (ii) a sodium ammonium phosphate salt or an ammonium phosphate salt, and (iii) water. The cooling agent is produced in a manner which avoids the conglomeration of the crystals, which was a difficulty in the art. Moreover, the cooling agen...

Endothermic reaction (dissolution) of endothermic material to be packed in a cooling bag is retarded to avoid a large temperature gradient which results in a meaningless intake of ambient heat quantity and an excessively low temperature condition, so as to keep an adequately cooled condition for a long period of time. Column-like or tablet-like endothermic materials are prepared from granular starting materials to decrease their specific surface area and solution velocity in water. The products,...

This invention discloses a device and a method for resuscitating the brain as result of ischemic and anoxic injuries whereby the patient survives neurologically intact. The device includes a head enveloping helmet and neck supporting back plate with interconnected hollow cavities to allow chilled fluid from an activated coolant source to pass therethrough and subsequently chill the brain and upper spinal column. Once chilled, the brain's metabolism is slowed whereby resuscitation efforts can con...

The invention provides an air cooling duct and a cooling apparatus which can effect ventilation and cooling with certainty while suppressing noise. The cooling air duct is provided on a wall of a housing, in which a heat source is accommodated, and inducts external air into the housing or vents air in the housing to the outside of the housing in order to cool the inside of the housing. The cooling air duct defines an air path for communicating the inside and the outside of the housing with each ...

A cooling tower with a non-self-supporting envelope which is supported by a net of cables and by pulling elements extending from a portion of a supporting post which portion protrudes upwardly beyond the outlet opening of the cooling tower mantle, in which annular means surround the outlet opening of the mantle and are connected to the supporting post by elements extending in a spoke-like manner from the supporting post and at least partially subjected to pull only.

A cooling system for circulating a fluid past a heat-exchanger comprises a vertical surge column and a cooling tower to reduce the heat level of a circulating fluid for delivery to the surge column. The cooling tower is mounted on the surge column which is adapted to support substantially the entire weight of the cooling tower. Heat-exchanger coils are provided which are coupled to the surge column to receive the circulating fluid therefrom and to return the circulating fluid to the cooling towe...

A cooling tower for condensing water has a hyperbolical main wall with an per portion which defines a passage for ascending vapor-laden air. The upper portion contains an annular insert serving to intercept currents of cool air which develop and tend to flow into the interior of the intermediate portion of the main wall at low wind velocities and/or to intercept turbulent air which develops and tends to flow into the intermediate portion when the wind velocity at the top of the tower is high. Th...

An improved cooling hatband is comprised of a structural support band which is affixable to the desired headpiece. An absorbent flexible liquid retaining band is attachable to the support band with a net fastener. The absorbent band is provided with a matrix of indented slots through which air can pass to optimize evaporation. The structural band is provided with a corresponding intermeshing matrix of openings which register with the intermeshing openings of the absorbent band when the absorbent...

A cooling installation for liquid-cooled internal combustion engines, for example, for use in armored vehicles, in the form of an annular radiator block which is traversed by the cooling air from the inside toward the outside and which includes a radial blower equipped with a rotor axially sucking in the cooling air through an opening of the vehicle housing and arranged on the inside of the annular radiator; a base plate is thereby rigidly connected with the vehicle part supporting the cooling i...

This invention relates to a portable seat cushion which unfolds to form a seat section and a back section. Both the seat and back sections include therein a frozen coolant package covered by a thermally transparent pad or cushion. The coolant package contains a liquid which may be frozen in the freezer section of an ordinary refrigerator and then placed within a recess in the seat and back sections of the seat cushion for absorbing heat, and thereby cooling the occupant of the seat cushion.
