摘要： A vent tube which is particularly useful for horizontal cryostat penetration comprises a plurality of conduit sections joined by mating rings which facilitate the incorporation of relatively deep circumferential grooves in the conduit sections. Thermal contact springs, preferably in the form of a single strip are disposed in these circumferential grooves so as to provide a means for transfer of thermal energy from the cryostat interior to the exterior either for general refrigeration requirements or for liquefaction of coolant vapor which may have boiled off from the cryostat interior. The cryostat which incorporates the present invention is particularly useful in housing NMR medical diagnostic imaging magnet and coil systems.
摘要翻译：特别适用于水平低温恒温器穿透的排气管包括多个通过配合环连接的导管部分，这些导管部分有助于在导管部分中引入相对较深的周向凹槽。优选以单条形式的热接触弹簧设置在这些周向槽中，以便提供用于将热能从低温恒温器内部传递到外部的装置，用于一般制冷要求或用于液化冷却剂蒸气从低温恒温器内部煮沸。结合本发明的低温恒温器在包含NMR医学诊断成像磁体和线圈系统中是特别有用的。

摘要： Apparatus for retaining a sorbent bed without permitting voids to be created and that can be readily handled by automated systems is disclosed. A solid phase extraction apparatus is disclosed that is most preferably comprised of a body that contains a sorbent bed and a cap that forms an axial sliding seal with the body. A sleeve is provided to retain the body and create an outside geometry similar to that of a standard glass vial. The sliding seal permits voids in the sorbent bed to be eliminated by axial compressive sealing forces. In a most preferred embodiment, conical sealing surfaces are provided at each end of the disclosed cartridge to facilitate removal of the cartridge after the axial sealing forces are released. The cap and the body are also provided with surfaces compatible with luer fittings, that provide flexibility and permit the use of the invention with existing fluid flow systems.
摘要翻译：公开了用于保持吸附剂床而不允许产生空隙并且可以由自动化系统容易地处理的装置。公开了一种固相萃取装置，其最优选由包含吸附剂床和与主体形成轴向滑动密封的盖体构成。提供套筒以保持身体并产生类似于标准玻璃小瓶的外部几何形状。滑动密封允许通过轴向压缩密封力消除吸附剂床中的空隙。在最优选的实施例中，锥形密封表面设置在所公开的盒的每个端部处，以便在释放轴向密封力之后便于移除盒。盖和主体还具有与鲁尔接头相容的表面，其提供柔性并且允许本发明与现有的流体流动系统一起使用。
