摘要： A process of bonding metal parts to one another to form seamless, hollow metal articles, particularly made from beryllium. Tooling is assembled to the parts, prior to hot pressing, to cause pressure to be applied to selective portions of the parts. The parts, assembled together with the tooling, are then subjected to hot isostatic pressing at a temperature of about 1700° F. to 1750° F., and at a pressure of about 2000 psi to 2500 psi, for around 3 hours. The tooling surrounding the metal parts functions to limit the amount of compression of the parts. Articles formed by this process are particularly useful in space flight applications because they are formed of a homogeneous material. Strength of the bond is enhanced because no filler metal is used. The absence of a filler metal also eliminates any thermal stress problems as a result of differences in coefficients of thermal expansion.

摘要： A bond joint and process of bonding metal parts to one another to form seamless, hollow metal articles, particularly made from beryllium. Tooling is assembled to the parts, prior to hot pressing, to cause pressure to be applied to flanges that extend peripherally from the parts. The parts, assembled together with the tooling, are then subjected to hot isostatic pressing of the flanges at a temperature of about 1700° F. to 1750° F., and at a pressure of about 2000 psi to 2500 psi, for around 3 hours. The tooling surrounding the metal parts functions to limit the amount of compression of the flanges. Articles formed by this process are particularly useful in space flight applications because they are formed of a homogeneous material. This means that the articles can operate under high pressure despite being subjected to temperature cycling. Strength of the bond joint is enhanced because no filler metal is used. The absence of a filler metal also eliminates any thermal stress problems as a result of differences in coefficients of thermal expansion.
摘要翻译：一种粘合接头和将金属部件彼此粘合以形成无缝的中空金属制品的工艺，特别是由铍制成。在热压之前，将模具组装到部件上，以将压力施加到从部件周向延伸的凸缘上。然后将这些与工具组装在一起的部件在约1700°F至1750°F的温度和约2000psi至2500psi的压力下进行约等于3小时的热等静压法兰。围绕金属部件的工具用于限制法兰的压缩量。通过该方法形成的物品在空间飞行应用中特别有用，因为它们由均匀的材料形成。这意味着尽管进行了温度循环，但制品可以在高压下操作。由于不使用填充金属，粘接接头的强度提高。不存在填充金属也消除了由于热膨胀系数差异导致的任何热应力问题。

摘要： A cryogenic thermal switch operates based on the principle of differential coefficients of thermal expansion of differing materials. A small gap is either closed or opened, dependant upon the relative dimensions of two pieces of differing materials. As the temperature of the pieces is raised, the piece having the greater coefficient of thermal expansion (CTE) increases its dimensions at a greater rate, causing a gap to open up. Conversely, when the temperature of the pieces is lowered, the piece having the greater CTE shrinks proportionally faster, thereby closing the gap. The present invention makes use of a reliable flat-faced geometry for the two sides of the gap.
摘要翻译：低温热开关基于不同材料的热膨胀系数的原理进行操作。取决于两件不同材料的相对尺寸，一个小间隙是封闭的或打开的。随着件的温度升高，具有更大的热膨胀系数（CTE）的件以更大的速率增加其尺寸，导致间隙打开。相反，当片的温度降低时，具有较大CTE的片段成比例地收缩较快，从而缩小间隙。本发明利用了间隙两侧的可靠的平面几何形状。
