Arrangement for the base seal of deposits and use of this arrangement

摘要

In order to be able to draw off and locate the media which have permeated into the cavity of a double sealing sheet, connecting pieces (5; 5') are provided at opposite ends. A carrier gas can thus be directed through the cavity. The media which have permeated into the cavity can be retained in downstream collecting devices, such as cooling traps or filters. <IMAGE>
