Abstract: INDUCTION HEATING ASSEMBLY INCLUDING AN  INTERPOSED CLOSED CONDUCTIVE LOOP FOR   SUPPRESSION OF INTERCOIL COUPLING                 Abstract of the Disclosure An induction strip heating assembly is provided having multiple induction coils disposed in coaxial tandem and including at least two coil power sources for generation of first and second inducing currents in the coils for the induction heating of a workpiece, such as steel strip, passing therethrough.  It is a feature of the invention that the assembly includes a closed loop of electrically conductive material coaxially interposed relative to the induction coils and disposed for induction therein of a circulating current opposite to a one of the inducing currents whereby a magnetic field of the circulating current in opposition to an inducing magnetic field of the inducing current causes a reduction in net magnetic field strength on a side of the loop opposite of the inducing current.  Such an assembly provides suppression of intercoil magnetic coupling so that the coils may be spaced adjacent one another with less space between them than would be required if no loops were used.

Abstract: ABSTRACT         In practice, switching is a continuously changing mixture of point-to-point connections, point-to-multipoint connections with low fanout, and point-to-multipoint connections with high fanout.  The switching elements of a switch optimized for point-to-point connections are additionally enabled to copy a few input signals for an arbitrary number of outputs, so that a very large number of copies is attainable for few input signals.          This switch is supplemented by a copy switch which serves exclusively to make limited numbers of copies for a large number of input signals, which are then switched in the (group) switch as point-to-point connections.  Point-to-point connections are operated as connectionless connections, but outside the switch act as virtual connections.  Point-to-multipoint connections are operated as virtual connections (connection-oriented) by means of connection tables.
