Abstract
841,402. Superconductive relays. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 23, 1958 [Jan. 29, 1957], No. 2307/58. Class 40 (9). In a bi-stable circuit comprising two superconductive elements G1, G2, each connected to a current source I in series with a control winding C2, C1 on the other element, the transfer of a superconductive state from one element to the other is initiated by selectively energizing one of two biasing conductors B1, B2. The outputs of the two elements are applied to respective control windings C3, C4 of further superconductive elements G3, G4 located in separate output channels 40, 41. In operation, to establish a resistive state in element G1, for example, switch S is opened for a short period during which bias switch S0 is closed. Similarly bias switch S1 is closed when it is desired to transfer the superconductive state of G2 back to G1 It is stated that the biasing field by itself need not be sufficient to destroy superconductivity in its associated element. In the arrangement described, the superconductive elements are tantalum wires, the bias wires, control windings and connecting leads are formed from niobium, and the operating temperature is such that niobium remains superconductive at all times.
