A device and a method for winding and twisting fibrous material in ring spinning and ring twisting frames are disclosed. The device and method allow the operating speed of the frames to be substantially increased, achieve higher productivity during ring spinning, and reduce the outlay, in terms of time and material, for assembling and servicing the device. This is achieved in that at least two high-temperature superconducting stators, together with the thermally connected cooling devices thereof, are arranged in a contactless manner and in parallel with one another along the progression of the spindle row, and the magnetic field-generating rotors, oriented coaxially with respect to the spindle, are introduced in a magnetically levitating manner in the magnetic field of the continuous intermediate space, between the stators which are adjacent in each case.

The disclosure relates to a device for improving a vacuum in the housing of a machine, in particular a centrifugal-mass energy store, comprising a rotor, for example a shaft having a centrifugal mass arranged thereon, which rotor is supported on at least one superconducting bearing in a contactless manner and is arranged in a vacuum container. In order to maintain the operating state of the superconducting bearing, the superconducting bearing is thermally connected to a cold source cooled by a cryogenic medium. According to the invention, the vacuum in the vacuum container is improved by means of an adsorber thermally connected to a cooling apparatus. The cooling of the adsorber occurs preferably by means of evaporated cooling medium from the superconducting bearing.
