Abstract: 969,531. Commutators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 3, 1961 [Aug. 29, 1960], No. 28251/61. Heading G4A. [Also in Division H3] A superconductive transmission line acts as a control conductor to superconductive lines arranged along its length, the whole circuit forming a commutator. The transmission line consists of a superconductive shield 12 separated from superconductive paths 26 and 28 except at the ends 26A, 28A by an insulator 13. A current source 18 is connected between terminal 20 of paths 26, 28 and terminal 32 on insulator 12. When source 14 is operated portion 38 of the line is sent resistive and the entire current from source 18 is sent to path 26. Source 14 is switched off and source 16 is operated. This sends section 42 (beneath conductor 41) of path 26 resistive and a sharp wavefront is transmitted-down the transmission line. The control conductor sections 51c to 56c of the transmission line are of different sizes requiring different values of current to send the associated gate conductors 51G to 56G resistive. In this way by controlling the size of the current from source 18 the conductors go resistive in different sequences. The resistance introduced into path 26 by source 16 equal to the characteristic impedance o. the tramsmission line. The current transmitted down the transmission line is half the magnitude of the current from the source 18. On reflection at the shorted termination 28A the current in the line builds up to the value of the current from the source. The value of the source current can thus be chosen so as to send resistive some of the gate conductors before reflection and the remainder after reflection. The Specification describes various other forms of transmission line including kinds in which a pulse once generated is reflected between the ends of the line for long periods of time due to there being no D.C. losses in the superconductive line.
