Abstract: The invention refers to a conveyor track with rollers for transport goods—in particular to a track with small-diameter rollers for workpiece carriers—provided, seen in the conveying direction, with multiple, consecutively arranged, braced support rollers which are a component of a side bar and bolt-equipped roller chain, whose bolts jut out sideways over the side bars and on which conveyor track support elements that proceed in the conveying direction are supported, and where the support rollers jut out over the side bars and the support elements in the direction of the transport goods.

Abstract: An electrically operated sanitary mixer tap system comprises a hollow piston (17) for adjusting the temperature, which in particular may be a rotary piston. The hollow piston (17) moves in a chamber (21) of the housing (1) of the mixer tap system, into which the flow paths (22, 23) for cold and hot water open. A particular structure (27) on the outside of the hollow piston (17) cooperates with the openings of the flow paths (23, 27) and thus determines the mixing ratio of the mixed water flowing out of the fitting. Its further path to the outlet of the sanitary fitting leads at least in regions through the interior of the hollow piston (17). Located at this point are (at least) the closing members (30, 34) of an electrically operated valve, which in this way controls the flow of mixed water to the outlet of the fitting. This arrangement of the closing members (30, 34) radially inside the hollow piston (17) facilitates a particularly space-saving construction (FIG. 4).
