This invention pertains to novel fibers made of .alpha.(1.fwdarw.;3) polysaccharides, and a process for their production. The fibers of the invention have "cotton-like" properties but can be produced as continuous filaments on a year-round basis. The fibers are useful in textile applications.

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 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....

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 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...
