Title: Superconductive switching device
IPC: G11C11/44
Filed: 1958-07-02
Abstract: 853,463. Superconductive elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1958 [July 2, 1957], No. 21211/58. Class 40 (9). [Also in Group XXXV] The inductance of a coil 12 (Fig. 3), is varied abruptly from a minimum to a maximum value by surrounding its ferro-magnetic core 10a with a thin shell 10b of tantalum, lead or other material which becomes superconductive at the temperature of the liquid helium in which the unit is immersed and by passing through control winding 14 a current which produces a field sufficient to shift the shell 10b out of the superconductive state. In its superconductive state shell 10b prevents the passage of magnetic flux through the core which it encloses. Inductance of winding 12 is thus small but increases abruptly when shell 10b is shifted out of the superconductive state. Parallel connection of a similar coil 10<SP>1</SP> as shown forms a two-position switch for alternating currents. With coil 14 energized and coil 14<SP>1</SP> de-energized the inductance of coil 12 is high while the inductance of coil 12<SP>1</SP> is low and most of the current flows through it. This situation is reversed by energizing coil 14<SP>1</SP> and de-energizing coil 14. The windings may be formed from a material such as niobium which .is superconductive at the operating temperature and is not shifted out of the superconductive state by the applied field. The core may be of ring-shape or other closed form. The apparatus is suitable for use with cryotrons and other superconductive circuit elements. In a modification the coupling between the primary and secondary windings 20, 22 (Fig. 4), of a transformer 15 is varied from a minimum level to a maximum level using a control winding 18 and a superconductive shell 1 6b covering the ferro-magnetic core portion 16a.

[Class 110 (i).] Pumping machines, driving-gear.-An hydraulic coupling associated with a centrifugal pump impeller employs the pump circulating liquid as coupling medium. As shown in Fig. 1 the part 4 of the coupling has radial vanes 5 and is made integral with the impeller 2. These parts are keyed to the shaft 3, and the co-operating part 6 of the coupling is keyed to the shaft 8 and has vanes 7. A cover 10 encloses the coupling and the space inside the cover communicates with the top of the impeller through a passage 11. Conduits 9 connect the impeller to the interior of the coupling. The shaft 8 may be driven by any convenient motor and, owing to the slip in the coupling, will rotate the impeller 2 at a speed corresponding to the amount of liquid in the impeller. Where a number of pump stages are used, the motor is arranged to drive the shaft 3 and impeller 2 at a constant speed and the coupling part 6 drives the impellers of the other stages at a speed which varies in accordance with the output of the impeller 2. In a modification, the vanes 5 of the coupling part 4 form part of the impeller blades. In another modification the liquid from the coupling is led to the impeller inlet through a passage which includes a throttle valve. In the modification shown in Fig. 4 the coupling is disposed between impellers 2, 2a. The coupling cover 10 is formed integrally with the impeller 2a and is attached to the coupling part 4 at the periphery, so that when the shaft 8 is driven, the two impellers and the shaft 3 are driven through the coupling.
