Abstract

1,073,960. Superconductor devices. AVCO CORPORATION. Dec. 24, 1964 [April 22, 1963], No. 50909/63. Heading H1K. [Also in Division H2] Current is induced in a superconductive circuit, which includes a plate member, by traversing a magnetic flux, which passes through a normal region in said plate, across said plate without breaking the circuit so that it effectively links with the closed circuit. In Fig. 2 (not shown), the superconductive circuit comprises a coil (46) and plate (21) situated in the air gap (22) of laminated core (23) which comprises pole member (24), yoke (25) and a second pole (26) which has depending legs (27-32) each carrying field coils (33-38) respectively. In operation, the field coils are sequentially energized through switch (54) so that the magnetic field produced, which is greater than the critical field of the superconductor, is traversed from edge (41) to edge (42) of the plate; coil (34) being energized before coil (33) is switched off and so on. All coils are then de-energized and the current may be increased by traversing the field from edge (41) again, or decreased by traversing the field from edge (42). In a modification the field of a continuously energized magnet is controlled by providing a matrix of continuously energized superconducting wires between the poles and the superconductive plate which are de-energized in sequence to cause the magnetic field to traverse the plate. In a further modification air-cored coils are used to provide the moving field, Fig. 8 (not shown). In another form of generator, Fig. 3 (not shown), the magnet core 62 or superconductor plate (64) is moved relative to one another; coil (61) being switched off during movement in one direction. It is also contemplated to use an A.C. energized field system in conjunction with a superconductive plate having copper plates on its surface so that localized eddy-current heating occurs thus causing the plate to become normal at this point.
