Abstract: The disclosure relates to a processing system for in particular pharmaceutical powders, and to a method for decontamination of such a processing system. The processing system includes a processing device for the powder, and a closed housing with an inner production space in which the processing device is arranged. The processing system further includes a steam generator via which water vapor is introduced into the production space in such a quantity that air supersaturated with water vapor develops there at least in some parts. Any powder residues present are bound via water since, on account of the supersaturation, water condenses in the production space. The condensed water, including powder residues bound therein, is removed, in particular with the housing opened.

Abstract: An adjustment construction for adjusting the active sheath length on a Bowden pull wire for mounting in an opening of a support wall. The arrangement includes a Bowden wire moveable in the sheath and a sheath end piece having an end into which the sheath is engageable, the sheath end piece having a surface defining a plurality of stops. The stops are positioned to provide gaps between adjacent stops and the sheath end piece is provided with a toothed rack-like displacement ribs on the outer surface of the plurality of stops. The periphery of the sheath end piece defines a longitudinal groove extending through the stops and interrupting the stops. A socket is provided for support of the Bowden wire. The socket is mounted in the wall opening and has a passage before the sheath end piece and the wire and includes an end engaged over the sheath end piece with a frictionally engageable end face. A support sleeve is provided having an interior bore engageable around the sheath end piece.
