A device for connecting two bodies, especially a quartz body and a metallic body, which assures with few and simply formed components a high sealing ability at high temperature differences and at very low pressures and makes possible an easy assembly and disassembly. The device for the vacuum-tight connecting of two bodies of different materials, each of which has an essentially tubular end section ( ) and in the connected state of which the tubular end section ( ) of the first body surrounds at least partially the end section ( ) of the second body, includes an intermediate conduit ( ) for intermediate suction removal of gases and is formed between the tubular end sections ( ) of the bodies with two seals ( ) which seal off the intermediate conduit ( ).

Device for the vacuum-tight connecting of two bodies of different materials

In a device for handling heavy components of a crystal puller according to the Czochralski method, a supporting beam that can be pivoted about one vertical leg of a supporting frame and vertically adjusted includes holding claws for accommodating components or auxiliary devices. Profile rails, on which a carriage can be laterally displaced, are arranged perpendicular to the supporting beam. The carriage can be connected to a receptacle for gripping and holding the crystal.
