Abstract: 1,193,262. Dynamo electric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 8 June, 1967 [16 June, 1966], No. 26819/66. Heading H2A. Apparatus for generating a persistent current in a superconducting circuit without causing any part of the circuit to go "normal" comprises a rotatable cylinder 30 mounted between two end support rings 31, 32, by means of roller bearings 33, and a load coil L connected to the rings by leads 38, 37. The cylinder has a radially directed permanent magnet M secured in a hole in the cylinder wall by epoxy resin 36 and is rotated by a thin walled hollow shaft 35. When the apparatus is superconducting, the flux from the magnet divides within the cylinder and passes out through the centre holes of rings 31, 32 to the external pole of magnet M so that on rotation this flux will link with the closed superconductive circuit. The whole arrangement including load L may be at cryogenic temperatures or alternatively leads 38, 37 may be connected to an external load, or to a power source if the apparatus is required to motor. In a modification a hole in cylinder 30 is used to transmit the magnetic field of an external electromagnet so that when the cylinder is rendered superconducting this flux is trapped in the hole and acts as a magnet.
