Abstract: An installation module for sanitary equipment, comprising a foamed support structure in which the elements needed for supply to and discharge from the sanitary equipment are embedded, comprising fastening connections for suspension or erection of the support structure, on the one hand, and for hooking up the sanitary equipment, on the other hand. The support structure is joined of plugged longitudinal and transverse profiled sections held together by the foamed material, preferably of two lateral sectional supports (1) defining the sides of the installation module and being interconnected by a transverse profiled section (2) inserted in the bottom area of the installation module. With their profiling and incorporated recesses/slits, the sectional supports plugged together present a substantially stiff-angled carrier structure.

Abstract: Device for connecting two parallel mounting channels (4,5) to one another during the installation of a temporary wall. An anchoring member (6,7) is inserted into each channel (4,5). Connecting pieces (1,2) have on one front end flexible stop lugs (1c), which interact with corresponding stop surface in the anchoring member (6,7). The two connecting pieces (1,2) are held together by a clamp (3) that is slid on. The device can be made largely of plastic and can be assembled quickly and reliably without tools.

Abstract: The molding has a body (3) of thermoplastic. A sound-muffling layer (4), which is affixed to the body (3) by the injection-molding process, consists of a thermoplastic elastomer. The body (3) protrudes at its end from the sound-muffling layer (4). Welding sleeves (2) are welded onto these unlayered areas (5) of the body (3). Molding (1) in the course of repair work can also be severed in the area of the sound-muffling layer (4) and joined by means of butt welding. The thickness of the sound-muffling layer (4) is comparatively small.

Abstract: The sealing stopper has a lid (1) which is set onto a sealing part (2) with a conical sealing surface (8), leaving an annular space (15). At the bottom side of the lid rim (11) is a protrusion with a hemispheric recess, into which an end segment (4) of a chain (3) is set. In this manner, the latter is directly and tightly fastened to the sealing body and has no protruding parts on its upper side which could interfere with use of the stopper in the drain valve of a bathtub.

Abstract: A drain and overflow device for bathtubs having overflows at different heights and various slopes. By rotation of a turning knob (6) adjacent the overflow housing (15), the body (8) of the drain valve (1) can be raised and lowered by means of a Bowden draw tube (10). A bellows (5) is inserted in the overflow conduit (11), and this enables adjustment of the length of the latter and orientation of the overflow housing (15) to the dimensions of the bathtub. In order to prevent twisting of the Bowden cable (12) during actuation of the turning knob (6), the cable is rotatably arranged on a cable bolt (28). For this purpose, an easily rotatable bearing (34) is inserted in an axial bore (33) of the cable bolt (28), and on this bearing rests a disc (36) to which the Bowden cable is attached.

Abstract: A flush valve mounting permitting adjustment of water flow to the requirements of different types of toilet bowl comprises a housing in which a float container with a float therein is removably emplaced. The lower portion of the housing has window apertures through which water can flow from the flush tank into a drain upon lifting of the pipe which carries the valve plate. A wall extending downwardly from the floor of the float container abuts the interior of the window openings, and this wall itself has through-flow apertures separated by webs formed by the wall. The openings in the window apertures are diminished by rotating the float container relative to the housing. This permits the water flow to be adjusted to the requirements of the particular toilet bowl.

Abstract: Partitioning for preventing the spread of fire or smoke through wall apertures created by the burning of plastic pipe. Pre-stressed metal squeezing elements are retained by plastic bolts which melt at about 120.degree. C., releasing the squeezing elements and permitting them to squeeze together the heat-softened plastic pipe. An insert of foamable material may additionally be used to supplement the aperture sealing effect.

Abstract: A pneumatic actuating device for a toilet flush valve, comprising a cap emplaced on the flush valve housing and having an integral hemispherical bell member extending laterally therefrom, the bell member containing a resilient membrane. A manual pusher provided with a similar hemispherical membrane is connected to the bell member by a hose. A pipe which carries the flush valve plate is connected to a hood having a piston which extends into the membrane in the bell member. Upon actuation of the manual pusher, air flows through the hose, deforming the membrane in the bell member and causing it to lift the piston, thereby opening the flush valve.

Abstract: A welding sleeve connector for the connection of molded components made of a thermoplastic synthetic resin employs the heat energy generated by pyrotechnical material. This connector has a thermoplastic sleeve and a plurality of pyrotechnical heating charges for producing the welding heat energy. Each charge is individually enclosed in a casing of a solid material arranged in the sleeve, and the encased heating charges are separately positioned in the sleeve at predetermined spacing from each other over the circumference of the sleeve. The connector also has a device for igniting the heating charges.

Abstract: The invention relates to a lift brake for exhaust water capable of installation in a vertical drain pipe system.

Abstract: An electrically heatable welding muff for connecting plastic pipes has a heating wire winding disposed in a helical groove in its interior wall. To position the pipes to be connected snugly and accurately, longitudinal grooves are cut in the interior wall of the muff so that the material forced out of the grooves projects inwardly, forming resilient retaining tabs.

Abstract: A device for swingably mounting a toilet seat, adaptable to variations in position and distance of the toilet bowl, and for removal and repositioning of the cover without need for adjustment. The device comprises a support member having a downwardly facing cavity, engaged by an elongated carrier connected to a mounting stud. The carrier has an undercut groove in which a nut is guided as a clampable slide ring engaged by a set screw arranged in a bore in the support.
