Abstract: A clamping arrangement for stainless steel fiber filter elements in the pressure relief channel of a safety containment of a nuclear installation. The filter elements are engaged at their edges by a clamping structure which is fully disposed within the duct walls defining the relief channel. The clamping arrangement includes a support frame mounted on the duct walls and a clamping frame disposed on the support frame and clamped thereto with the edges of the respective filter element clamped therebetween such that any leakage through the clamping arrangement is still contained by the duct walls.

Abstract: In a mist collector for separating drops of liquid from a gas or vapor stream and including a cylindrical housing and metal fiber webs mounted in an annular configuration in the housing and arranged to be penetrated by the stream in the radial direction of the housing, the metal fiber webs are composed of a plurality of cylindrical layers spaced apart from one another in the radial direction and the collector is provided with stream conducting elements positioned and arranged with respect to the housing for causing the stream to flow through the layers in a radial inward direction.
