摘要: An insulated dual-bayonet connector is provided. The connector provides simple alignment and connection for both fluid tubes of a fluid recirculation system. The connector is especially useful for closed-cycle systems, but is also useful for open-cycle gas systems where it is desired to vent a gas in a desired location remote from the item to be cooled or heated by the gas.

摘要: A resonant coil for nuclear magnetic spectroscopy and microscopy is provided, in which the coil is in the form of nested, interrupted loops of a conductive material forming a distributed inductive element and having a plurality of capacitive elements with capacitance distributed over the periphery of the loops. The coil is preferably formed as a thin film of a superconductive material on an electrically nonconductive substrate.

摘要: Inhomogeneities in the magnetic field in the vicinity of a superconducting NMR receiver coil are avoided by placing the probe, at about room temperature, within the magnetic field, cooling rapidly to just above the critical temperature of the superconductor and then controllably cooling the coil to operating temperature at a rate of 3 K./minute or less.

摘要: A cryogenic refrigerator cools a heat source by cyclically concentrating and diluting the amount of .sup.3 He in a single phase .sup.3 He-.sup.4 He solution. The .sup.3 He in superfluid .sup.4 He acts in a manner of an ideal gas in a vacuum. Thus, refrigeration is obtained using any conventional thermal cycle, but preferably a Stirling or Carnot cycle. A single phase solution of liquid .sup.3 He at an initial concentration in superfluid .sup.4 He is contained in a first variable volume connected to a second variable volume through a superleak device that enables free passage of .sup.4 He while restricting passage of .sup.3 He. The .sup.3 He is compressed (concentrated) and expanded (diluted) in a phased manner to carry out the selected thermal cycle to remove heat from the heat load for cooling below 1 K.
摘要翻译: 低温冰箱通过在单相3He-4He溶液中循环浓缩和稀释3He的量来冷却热源。 超级流体4He中的3He在真空中以理想气体的方式起作用。 因此,使用任何常规热循环,但优选为斯特林或卡诺循环获得制冷。 在超流体4He中初始浓度的液体3He的单相溶液被包含在通过超滤装置连接到第二可变体积的第一可变体积中,其允许4He自由通过,同时限制3He的通过。 3He被压缩(浓缩)并以相位方式膨胀(稀释),以执行所选择的热循环,以从热负载中除去热量低于1K。
