摘要： Ceramic superconductor materials, e.g., of rare earth/alkaline earth metal/transition metal/oxygen type, contain an effective stabilizing amount of fluorine atoms distributed therein in a concentration gradient decreasing from the external face surface of the material to the core region thereof; advantageously the fluorine atoms are principally distributed in an external protective diffusion barrier layer.

摘要： A pipe coupling device, especially suitable for use in cryogenic systems, including a plurality of arcuate collar segments each having a radially extending inner groove with cam surfaces to grasp flanges at the ends of a pair of pipes to be coupled together in a fluid-tight arrangement. The ends of the collar segments are pivotally interconnected to a generally circular configuration having a pair of adjacent unconnected end portions. Means are provided for clamping the end portions of the collar together and for pressing the collar segments against the pipe flanges. A hydraulic jack is provided for forcing the end portions of the collar segments apart and for pivotally moving the collar segments radially outward from the pipe flanges when the pipes are to be disconnected. Flexible protectors about the pivot connections facilitate the breaking of ice which may form around the coupling device.
摘要翻译：一种特别适用于低温系统的管连接装置，包括多个弧形环形段，每个弧形环段具有径向延伸的内槽，凸轮表面在一对管道的端部处能够以流体密封的方式联接在一起安排。轴环段的端部枢转地互连到具有一对相邻的未连接端部的大致圆形构造。提供了用于将套环的端部夹紧在一起并用于将套环段压靠在管道凸缘上的装置。液压千斤顶被设置成用于迫使套环段的端部分开，并且当管要断开时用于将管段从管道凸缘径向向外枢转运动。围绕枢轴连接的柔性保护装置有助于破坏可能在联接装置周围形成的冰。
