Patent NO-178670-C (NO)
Inventor: JOHANSEN TORE
IPC: B23K11/06
Filed: 1993-12-14
Abstract: A machine for seam welding overlapping heat weldable lengths of covering, comprising a wheel-borne frame (1) having a heating element (33,34) suspended on one side designed for insertion between an underlying and an overlying length of covering. The machine has pressing means (18,19) and driving wheels (11,12) for compressive stress of the upper side of the overlying length of covering and for movement of the machine in the longitudinal direction of the overlapping seam or lap. To make possible wheel transport of the machine, with the heating element raised from the underlying surface, and to make possible an easier guiding of the heating element between the two lengths of covering in the lap, the machine has especially positioned transport wheels (26,27) which in the welding position will be lifted clear of the underlying surface, but by tilting the machine can be brought into contact with the underlying surface, so that the machine can be wheeled by means of the transport wheels. The heating element is suspended such that its leading edge will have the initial contact with the underlying surface, whereby the guiding and insertion of the heating element between the lengths of covering are facilitated and any damage to the lengths of covering as a consequence of premature and/or undesired contact between a hot heating element and the underlying surface is avoided. <IMAGE>

Filed: 1991-11-06
Granted: 1996-09-17
Abstract: A magnetic refrigerator comprising a magnet generating a high-intensity magnetic field, a tube-shaped superconducting magnetic shield, a magnetic working material and a reciprocating means for reciprocatively moving the superconducting magnetic shield or the magnetic working material, the magnetic refrigerator being arranged such that a magnetization process wherein the magnetic working material is magnetized in the high-intensity magnetic field and a demagnetization process wherein the magnetic working material is demagnetized by being accommodated in the hollow section of the magnetic shield are repeated by the reciprocating means so that the magnetic working material generates coldness.   By using the property of a tube-shaped superconductor which can shield the magnetism of an external magnetic field passing through the hollow section of the tube and can generate a zero-intensity magnetic field in the hollow section, the magnetic working material magnetized in the high-intensity magnetic field generated by the magnet is inserted into the hollow section of the tube-shaped superconducting shield and is demagnetized in an adiabatic condition to generate coldness.  This coldness is used to cool the target cold bath.
