this citation summarizes a one-page announcement of technology available for utilization. technology developed during the design of cooling systems for space suits has been applied to cooling of sportswear for athletes. the main components are a patented refrigerator-cooled cartridge that slips into insulated pockets in the clothing plus a special absorbent, blended fabric. this cooling system makes it less tiring to perform strenuous activities by removing excess body heat from such areas as the forehead, neck or wrists where heat transfer is particularly efficient. many athletes have reported dramatic improvements in their performance in hot weather when using garments like head bands, wrist bands, visors, and caps. the garments resulted from the combining of bio-engineering, cooling technology, and modern fabrics. the principal element of the cooling system -- the gel cartridge -- is a more efficient version of the 'blue ice' pack sold for picnic coolers. one cartridge can remove as much as 200 btus of heat per hour, which is 70 of the heat produced by the body at rest. after chilling they are inserted into the insulated pockets of the garment between a reflective-coated heat shield and an inner cloth surface. typically, cartridges used by runners in extremely high temperatures last 45 minutes or more when the garment is dry. the major users of this cooling technology are found among joggers and runners. other users are found among tennis players, cyclists, football players, or among oil field workers who work where ground temperatures can exceed 137 degrees f. in such
