摘要:
Sealing means for sealing spaces between at least two bodies comprising a magnetically influencable sealing compound positionable between said bodies and at least one magnetising device for magnetisation of said sealing compound to form a sealing lip extending between said parts; said sealing compound being flowable in at least the non-magnetised state and adapted to stiffen under the influence of a magnetic field.
摘要:
A pressure lock system for introducing workpieces successively into and out of a high vacuum work chamber, comprising inlet and outlet lock channels communicating with said chamber through which a series of workpiece support elements comprising pistonlike sealing elements connected in spaced relation by intermediate elements are moved as a chain, either continuously or intermittently. If desired, any workpiece supporting element within the chamber may be detached from the chain and moved in various directions within the chamber while work is performed on the workpiece.
