Description

Supplementary transfer lock

The invention relates to a transfer lock, as' they are for the transfer of material, equipment and waste from inside a contaminated environment to the outside or vice versa v / ird, i.e. for the transfer of material, equipment or waste from a closed working chamber, for example in a work cell

For the implementation of such transfers are also State of the art simple locks known, which in general * installed in the shielding of the work cells Chambers exist, which with two sealingly closing Doors are provided to connect the outside and inside of the cell in the course of an overpass Avoid atmosphere · In general there is some transmission of contamination the air and the material inevitable when operating with conventional systems

For safety reasons, especially because of the risk of contamination and corrosion of the materials, it is desirable that the
