The invention relates to a plate-type heat exchanger comprising a stack of double-walled heat exchanger plates (30 32) which are permanently interconnected and each include two plate members (33, 34) having a central heat transfer portion (35) and an edge portion (36) bent upwardly with respect to the plane of the central heat transfer portion (35), separate flow passage spaces for at least two heat exchange fluids being defined between the double-walled heat exchanger plates (30 32), the two pl...

A method and system for mapping nodes in an M.times.N torus interconnection fabric of nodes is provided. The method includes generating an observed mapping of the nodes in the interconnection fabric showing a location of a first node relative to an x-axis of the fabric and relative to a y-axis of the fabric, comparing the observed mapping of the nodes to a set of expected mappings, and identifying the expected mapping which is most similar to the observed mapping.

A magnetic refrigeration apparatus (10) is modular in design, so that housing modules (14) are alternately stacked with superconducting magnet pairs (24). Each module (14) has a wheel (16) that is rotated through the module (14), the wheel (16) having cutout regions (18) into which elements (20) of magnetic material are inserted. Each cutout region has two elements (20) separated by a wave spring, the wave spring biasing the elements (20) against the housing module (14) so that the elements (14)...

A rotor assembly may include first rotor half, a first spring supported with the first rotor half, a second rotor half, and a second spring supported within the second rotor half, wherein the first rotor half and the second rotor half are adjoined to enclose the first and second springs. A coiled section of each spring may surround a rotor center pin. A contact arm positioned between the springs may include a non-circular opening. A method for assembling such a rotor assembly is further describe...

A method for simultaneously coating multiple thin layers of relatively viscous fluids comprises the adjustment of the pressure gradients in the interface region between two confluent flows. In particular, the pressure gradient along the middle lip is regulated so as to not be excessively positive, in order to position the separating line of the top flow at a particular point on the die lips, thus enhancing stable flow. In one aspect of the method, a step configuration is designed into the die li...

A protection device which is active during the manufacturing process of a semiconductor chip includes a protection transistor and an antenna. The protection transistor is connected between a metal line having devices to be protected electrically connected thereto and a ground supply, where the metal line is connected to devices to be protected. The antenna is formed of the same metal layer as the metal line and controls the operation of the protection transistor during the manufacturing process....

A heating device for the electromagnetic induction heating of a metal strip traveling in a specified direction. The device includes at least one electric coil arranged opposite at least one of the large surfaces of the strip so as to heat the latter by transverse magnetic flux induction, each coil being associated with at least one magnetic circuit. Each circuit is divided into a plurality of magnetically independent bars arranged parallel to the direction of travel of the strip. The bars may mo...
