摘要： A pratical cryogenic Peltier cooler (22) is devised by replacing one of the semiconducting elements in a conventional Peltier cooler with an element comprised of bulk, or thin film superconducting material. In the preferred embodiment, a rare-earth, a barium copper oxide superconductor (78) of the form RBa2Cu3Ox is utilized. The superconducting elements (78) are placed in an alternating series with semiconducting elements (72) comprised of bismuth telluride of the form Bi2Te3 (n-type). Performance may be improved in an alternative embodiment by utilizing instead a bismuth antinomy semiconductor of the form Bi85Sb15 (n-type). As a result, cryogenic Peltier coolers can be devised with useful refrigeration capacities and stable cold temperatures of 65-80 degrees Kelvin and below, while heat sinked to a higher temperature.

摘要： A high temperature superconductor (HTSC) 5 is magnetized between drive coils 1,2 forming poles of a magnet connected by an iron yoke 9 by relative movement of a vacuum insulated cryostat 4 containing the HTSC and the magnetizing magnet, in order to magnetize a large area of HTSC using a magnet with a small region 3 of magnetizing flux. Alternatively, the HTSC 5may be contained in an evacuated region of a cryostat containing the magnetizing magnet. An interconnecting chamber allows the HTSC to be moved between an operative region and a magnetizing region without substantial loss of vacuum.

摘要： A spring loaded valve for use with a cryostat insert is provided for selectively directing liquid cryogen to the bottom or top of a supercoolable vessel. The spring loaded valve situated at the tip of the insert extends into a housing in the top of the supercoolable vessel. A slidably mounted sleeve extends inside a cryogen fill tube. The sleeve is spring loaded and when the valve is inserted in the housing the fill tube covers apertures in the sleeve allowing fluid to flow from the fill tube through the end of the housing past the valve head. When the spring loaded valve is partially retracted from the housing the holes in the sleeve are uncovered and liquid can flow from the fill tube to a passageway in the housing extending to the bottom of the supercoolable vessel. The valve closes the aperture leading to the upper portion of the vessel.

摘要： A cryostat including a source of refrigeration disposed within an evacuated chamber containing a reservoir of liquified cryogen wherein refrigeration is directed to heat stations disposed in the access means to the reservoir to intercept heat leak into said reservoir and to recondense cryogen boil-off from said reservoir. Thermal convective couplings are used to cool the heat stations and to minimize heat leakage in the event the refrigeration source is disabled. Cryogen boil-off is condensed in an apparatus utilizing low thermal conductive conduits to direct the vapors to a refrigeration zone and return the condensed cryogen to the reservoir.

摘要： The rotary dipole active magnetic regenerative refrigerator (10) of the present invention comprises a stationary first regenerative magnetic bed (12) positioned within a stationary first inner dipole magnet (14), a stationary second regenerative magnetic material bed (16) positioned within a stationary second inner dipole magnet (18), an outer dipole magnet (20) that rotates on a longitudinal axis and encloses the inner dipole magnets (14, 18), a cold heat exchanger (22), hot heat exchangers (24, 26), a fluid displacer (28), and connective plumbing through which a heat transfer fluid is conveyed. The first and second regenerative magnetic beds (12, 16) are magnetized and demagnetized as the vector sums of the magnetic fields of the inner dipoles magnets (14, 18) and the outer dipole magnet (20) are added together upon rotation of the outer dipole magnet (20), such magnetization and demagnetization causing a correlative increase and decrease in the temperature of the magnetic material beds (12, 16) by the magnetocaloric effect. Upon magnetization of any particular magnetic material bed (12 or 16), fluid flow is forced therethrough in the connective plumbing by the fluid displacer (28) in the direction from the cold heat exchanger (22) to one of the hot heat exchangers (24,26). Upon demagnetization of any particular magnetic material bed (12 or 16), fluid flow is reversed by the fluid displacer (28) and is forced in the direction from one of the hot heat exchangers (24, 26) to the cold heat exchanger (22).
