Sports wear apparel in the form of wrap around headbands or the like is provided with a tube of plastics sheet material defining pockets filled with refrigerant gel. The tube is composed of a thin plastics material film coated and covered on the outside with a nonabsorbent and nonporous foam integrally bonded on the film. This foam meters heat transfer from the refrigerant gel to the skin of the wearer and provides pockets which trap moisture from the skin and then permit the moisture to evapora...

The present invention relates to a device for cooling an electrode holder (1) for manual arc welding with coated electrodes, as well as the electrode (4) and the electric supply cable (5), said cable (5) being surrounded by a tube (10), and said electrode holder (1) comprising a handle (2) provided with a projecting electrode pin (11) having threads (12) and a conical tip (13), and a top part (3) having a bore (16) provided with threads (17) and arranged to receive the electrode pin (11), and a ...

A heat conducting thermal plate (55) is fixed to a thermal load (10) by means of fasteners (75). Bosses (60) on the thermal plate are received within bosses (75) on an adjacent heat exchanger (25) to maintain a sealed interengagement between those components as the thermal plate is drawn up into surface-to-surface contact with the load.

On the cooling roll with outer roll shell 7 and inner, preforated roll shell 8 of an inner body 6, the inner body features endways and centrally at least one distributing component 22. Extending through this distributing component are channels 19 that are parallel with the roll axis, for one, and interposed radial channels 28 which, for one, serve the connection of an endwise space 14 that is located between an axial end of the inner body and the hollow roll end with one of the coaxial supply or...

A Stirling cycle cooling engine with separate linear motor drives for the compressor and displacer, the drives being powered by a common oscillator via respective look up table/digital to analog converter circuits and respective displacement regulating servo-loop circuits and to regulate the temperature of the element cooled by the engine, a temperature sensor arranged to control the amplitude of the compressor piston displacement.

A cooling apparatus comprises a cooling chamber (2), means (4) for introducing liquefied gas or its cold vapor thereinto, an exhaust passage (16) having flow inducing means associated therewith and a heat transfer means (46) associated with said exhaust passage (16) in which the heat transfer means operates to transfer heat from a heat source to the exhaust gas.

Cooling apparatus is disclosed which comprises a reservoir for compressed, preferably liquified, gas, the reservoir being connected to tubing 130 arranged to be disposed in an article of clothing adjacent to the skin of a user. A solenoid 230 is provided for opening a valve 240 between the reservoir 100 and the tubing 130 to allow pressurized gas to evaporate and escape from the reservoir along tube 130. As the gas evaporates it cools due to latent heat of evaporation thus providing a cooling ef...

A cooling system which can be fastened on a ceiling with a suspension provided beneath the ceiling disposed above a space to be cooled and with cooling pipes between the ceiling and the suspension wherein the space to be cooled and the space between the ceiling and the suspension are connected with each other through air current paths.

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 o...

A cooling vest arranged with a pocket between a denim outer layer and a linen inner layer to receive a flexible vessel containing separate pockets filled with water. The vessel is releasably attachable to the vest and in use the water is cooled or frozen before the vessel is fitted in the pocket. The vest is used for cooling the body of a user either during recreation, or while working in hot conditions or a person who is allergic to dust particles mixed in air emitted from electric air-conditio...
