Abstract: A filter element for cleaning liquids, having a stack of at least two filter membrane pockets, which are substantially flat and include a flexible, liquid-permeable filter material for retaining waste particles and/or microbes, wherein each filter membrane pocket has a substantially polygonal shape with at least three corners and a corresponding number of edges, wherein the filter membrane pockets are stacked with a defined distance and aligned with each other, wherein aligned corners of the filter membrane pockets are embedded in a casting covering only part of the adjacent edges such that the casting for each corner is spaced from the castings of the neighboring corners.

Abstract: A combination wall mounted dance barre and exercise rod. A pair of longitudinally spaced supports have mounting plates on one end thereof for mounting the said supports on a wall with the supports projecting laterally from the wall. The supports have grooves adjacent the free ends thereof extending parallel to the direction in which the supports are spaced and a rod is positioned in the grooves. The rod has holes therethrough at least at the positions at which the rod is supported in the grooves on the supports. A quick release bolt is horizontally slidable in each support for movement into and out of the holes for removably holding the rod in the grooves and preventing the rod from rotating about the longitudinal axis thereof relative to the supports. When the rod is mounted on the supports it serves as a dance barre and by moving the bolts out of the holes the rod can be removed from the supports and be used as an exercise rod.
