Abstract: The submarine is equipped with a fluid gas pressure container, in particular for storing liquid oxygen. The liquid gas pressure container is arranged within the pressure hull of the submarine and is surrounded by an outer pressure container which is likewise stored within the pressure hull of the submarine. A device is provided which on exceeding a predefined pressure within one pressure container leads fluid from the pressure container out of the pressure hull.

Abstract: The invention relates to a plastic cartridge system including a cartridge having a plastic-covered column, said column including a monolithic sorbent and at least one closing cap which is applied to the ends of the column. The cartridge also includes a connecting system having at least one divided supporting screw which is held in position by a closing cap or a spacer ring, and at least one end piece which can be screwed onto a supporting screw in order to connect an elution agent inlet and an elution agent outlet.

Abstract: The invention relates to a chromatography columns, consisting of metal tubes which are filled with sorbent and which are provided at both ends with distributed and sealing elements. Screw unions for connecting capillaries are utilized, which unions consist at least of a supporting nut fitted to the column tube and a cap nut. The supporting nuts consist of two half-shells which can be removed from the column tube after the cap nut has been unscrewed. By so configuring the columns, the same tube column can optionally accommodate precolumns.
