Abstract
The operation and construction of a leak‐free seal, by means of which limited translational and unlimited rotational motion in a vacuum can be obtained, is described. The seal is accomplished by using a rubber gasket in combination with a liquid which is in equilibrium with internal and external pressure. This seal can be operated from zero to several thousand rpm and can be used at 10−9 mm Hg and lower without difficulty. The seal has distinct advantages for use in space environment simulation chambers and other ultra‐high vacuum apparatus.Keywords
