摘要： A vapor trap is placed in fluid communication with the vapor exhaust pipe of a supercooled rotor between, and in fluid communication with, the helium reservoir of the supercooled rotor and the portion of the exhaust pipe which is in contact with the torque tube of the rotor. By preventing a reverse flow of heated helium gas through the exhaust pipe toward the helium reservoir, the vapor trap of the present invention improves the operation of the rotor's vapor pump. Operating in a manner similar to liquid traps, the present invention blocks the passage of heated helium vapor in a reverse direction and thus improves the overall operation of the supercooled rotor.

摘要： A radiation heat shield which comprises a plurality of helical grooves distributes possible thermal expansions around its circumference. These potential thermal expansions could be caused by transient conditions or other abnormal operational modes which could reduce the flow of coolant through particular fluid passages of the radiation shield. By incorporating a plurality of helical fluid passages, these potential thermal expansions are distributed around the circumference of the radiation shield and the resulting distortion moments tend to cancel each other and, provided that a sufficient number of turns is possible, eliminate the imbalance.
摘要翻译：包括多个螺旋槽的辐射热屏蔽围绕其圆周分布可能的热膨胀。这些潜在的热膨胀可以由瞬态条件或其它异常操作模式引起，这些模式可以减少冷却剂通过辐射屏蔽体的特定流体通道的流动。通过结合多个螺旋流体通道，这些潜在的热膨胀分布在辐射屏蔽的周边周围，并且由此产生的变形时刻倾向于彼此抵消，并且如果可以有足够的匝数，则消除不平衡。

摘要： A cryogenic lead is described which comprises a plurality of tubular conductors arranged in parallel association and connected to two conductive blocks. Each tubular conductor is a laminar assembly of an inner conductive sleeve and an outer sleeve which acts as a thermal mass to absorb heat from the inner sleeve during thermal perturbations. A fluid refrigerant is directed through the tubular conductors. Each tubular conductor has at least one flow restrictor disposed within its inner sleeve to reduce the relative effect of changes of refrigerant viscosity on pressure drop within the tubular conductor and to block the transmission of thermal radiation through the tubular conductor.

摘要： A vapor trap is provided for use in a liquid coolant supply pipe of a superconductive generator. The supply pipe has interiorly located, a flow constriction, an annular liquid coolant dam, and means for blocking the vapor flow through the central portion of the supply pipe. These act cooperatively to prevent the coolant vapor within the generator from flowing back through the supply pipe. This would be an undesirable condition most likely to occur during transient operating conditions when the normal flow of liquid coolant is temporarily stopped.

摘要： A cryogenic system, such as a superconducting magnet assembly of magnetic resonance imaging equipment, is cooled by a refrigeration unit having a first surface refrigerated to a desired temperature. The first surface has a indentation in which an indium body is bonded to the first surface. A copper thermal conductor has a second surface on which an indenter is formed. Preferably the indenter is either a spiraling peak or an array of pyramids projecting from the second surface. A mechanism is provided to hold the thermal conductor against the indium body with the indenter penetrating the body.

摘要： An apparatus is provided for rapidly restarting the flow of coolant through the cold electromagnetic shield of a superconducting rotor following a thermal transient episode. A vortex diode inhibits coolant flow in the undesirable reverse direction and encourages the reestablishment of a normal thermosyphon cooling loop flow quickly following the termination of a thermal transient such as that caused by transmission line faults. The present invention requires no moving parts and may therefore be permanently sealed in the superconducting rotor without risk of costly repair efforts caused by components failure.

摘要： A cryogenic liquid coolant transfer device enhances flow of a liquified gas in the inboard direction by the incorporation of a threaded insert in the rotating inlet pipe of a superconducting rotor. The threads of the device also facilitate the reverse flow of liquid helium back into a stationary supply tube during fault conditions. The objective of the insert, during both normal and abnormal conditions, is to inhibit the flow of liquid coolant into the clearance gap that exists between rotating and stationary parts of the liquified gas transfer system.
