Abstract: A forming tool for extrusion has a die (5), which has a forming cavity (6) having at least one critical reference value. The die (5) is surrounded by a biasing ring (8), which bears against it with radial pre-stress. The die (5) and the biasing ring (8) have tampered contact surfaces (11) and are displaceable relative to one another. The biasing ring (8) is surrounded by a reinforcement (9), which bears against it with radial pre-stress. The biasing ring (8) and the reinforcement (9) are mounted in a fixed position on a carrier (housing 1). The die (5) is displaceable relative to the carrier and capable of being locked, by locking means (15, 19) on the carrier, in positions that can be selected. By that means it is possible subsequently to carry out a fine adjustment of the critical reference value over a wide correction range.

Abstract: An air conditioning reactor is provided for producing high temperature, high pressure refrigerant in an engine driven air conditioning system. The system derives power from the waste heat from the coolant of an exothermic engine. The reactor has a double chamber construction which includes an inner chamber and outer chamber. Low temperature refrigerant vapor flows into the inner chamber while high temperature coolant flows into the outer chamber and around the exterior of the inner chamber, thereby raising the temperature and pressure of the refrigerant inside the inner chamber, and causing release of high pressure, high temperature refrigerant out of the inner chamber of the reactor. The reactor can therefore eliminate the need for a compressor in an air conditioning system by utilizing the waste heat in the coolant flowing out of a thermal combustion engine to produce high pressure, high temperature vapor.
