摘要: A probe for fiber optic spectroscopy, having a radiation transparent window for the emission of radiation and an optical fiber that extends through the interior of a hollow housing, surrounds the fiber with a cushioning sleeve to provide an optical cable that preserves optical fiber connections and dampen vibration of the optical cable. The sleeve provides a structure around the optical fiber that is more compressible than the optical fiber and has a significantly greater mass than the optical fiber. Excess cable length may be provided along its path through the housing to impinge the cable against the interior walls of the housing and thereby dampen vibration by providing additional node points through contact of the sleeve with the housing wall. Helical twisting of the cable along its path through the housing further stabilizes the shape of the fiber optic cable within the housing and maintains a regular spacing of contact points with the housing. Regular spacing of node points consistently controls vibration dampening by contact between the housing wall and the cable.

摘要: Presented is a vacuum valve having a metallic housing that may be mounted in a vacuum system in any attitude. The valve includes a "knife" edge seal formed on the interior of the metallic housing on one wall thereof, surrounding a port therein, and adapted to sealingly impinge against a metallic sealing pad mounted within the housing on a carriage that is translatable longitudinally of the housing by manipulation of a spindle that cooperates with a bellows sealing the housing. The spindle extends out to the housing and includes means for suitable manipulation of the spindle. Means are provided within the housing operatively interposed between the carriage and sealing pad to effect lateral translation of the sealing pad in relation to the carriage on which it is mounted to engage and disengage the "knife" edge seal upon appropriate rotation of the spindle. Means are also provided within the housing to prevent seizing of metallic parts that move relative to one another within the vacuum valve.
