摘要： For the transmission of electrical current, determined superconducting current carriers are accommodated in a cryostat, in which they are cooled with an undercooled cryogenic cooling medium, e.g. liquid nitrogen. The current carrier is electrically connected at the ends thereof to two normally conducting current supply means. The cooling medium is undercooled from a storage container to a temperature below its boiling temperature and supplied to the cryostat via a cooling medium inlet, brought into thermal contact with the superconducting current carrier, and subsequently discharged via a cooling medium outlet of the cryostat. According to the invention, the cooling medium from the cryostat is to be used for cooling at least one of the normally conducting current supply means.

摘要： 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.

摘要： A super-cooled liquid medium, preferably super-cooled liquid nitrogen, is pumped through a sub-cooler and cooled by the same medium that evaporates in the vacuum. This super-cooled nitrogen is used as coolant for a consumer. If a small amount of heat is emitted by the consumer to the nitrogen, the liquid medium can be guided in the circuit wherein the sub-cooler is arranged. For compensating volume fluctuations, such a circuit requires a compensation vessel, which is very expensive and can only be operated in the presence of a super-cooled medium when either a part of the medium is heated using external energy, or an inert gas which boils at very low temperatures is used as a pressure compensation medium. According to the disclosure, when a supply container for the liquid medium is integrated into the cooling circuit and used as a compensation vessel, a separate compensation vessel is not required.

摘要： A method for recycling argon from an industrial process; in which the gaseous argon is compressed after the use thereof in the industrial process, is fed to a main heat exchanger and is cooled there in contact with a first cooling medium. The compressed and cooled argon is fed to a rectification column or another cryogenic separating device and is liquefied there by direct heat exchange with a second cooling medium and is freed of low-boiling substances by rectification. The liquefied argon is drawn from the bottom of the rectification column and, after use as the first cooling medium in the main heat exchanger, is fed back into the industrial process, the raw argon being brought into thermal contact with cryogenically liquefied pure argon in the main heat exchanger and/or the rectification column. The product argon that results is highly pure and can be fed back to the industrial process.
