A holding arrangement is disclosed which can be employed to hold a winding enclosure which contains a low-temperature-cooled electric winding on which alternating external forces act, and which is fastened within a vacuum tank by means of tie rods. In particular, the arrangement includes pre-tensioned tie rods which are arranged to unilaterally pull, via pressure posts, with force-transmitting contact the winding enclosure against the inside walls of the vacuum tank. More specifically, the tensioning force at room temperature is selected such that at low termperature a residual tension force remains which is always at least as large as the component of the external force opposing it. With such a design for the holding arrangement no readjustment devices are necessary and the heat conduction effected thereby is relatively minor.

A continuously operating superconducting magnetic separator for the segregated separation of particles with different magnetic susceptibility from a mixture such as a mixture of ferromagnetic and non-ferromagnetic ore and rock, in which the magnetic separator comprises a stationary superconducting magnet arrangement along with at least one carrier running through the magnetic field for the particles to be separated, which particles are moved by means of a conveyer chute through the magnetic field of large volume and past the carrier, which is in the form of a ferromagnetic grid, generating a field gradient and forcing the particles onto the grid, from which they are carried to appropriate collection devices.
