Abstract: A sanitary fixture with a mounting housing which has a thread for fastening to a mating thread provided on the water outlet of a sanitary outlet fitting. The mounting housing has a downstream housing end side with flow-through holes, and wherein at least one insertion part can be inserted into the mounting housing as far as an insertion stop. The fixture has an aerated jet regulator or is configured as such, so a circumferential wall of the mounting housing borders at least one aeration duct at least in a subregion of at least a double-walled configuration, and the at least one aeration duct, which is open towards the downstream housing end side, opens out in at least one aeration opening leading into the housing interior of the mounting housing.

Abstract: A sanitary functional unit with a housing releasably fastened to the water outlet of a sanitary outlet fitting, the housing having an outflow-side housing end face with outflow openings. The outflow-side housing end face has at least one slot, opposing longitudinal sides of which form turning engagement surfaces or tool engagement surfaces for a turning tool that is releasably inserted into the slot, and the housing of the functional unit is rotatably held on the water outlet of the outlet fitting and/or the housing end face is mounted rotatably in the housing. Using the turning tool in the slot, a pivotably mounted housing end face in the housing can be easily aligned and/or the turning force required for fitting and removing a screw connection provided between the outer housing periphery and the inner fitting periphery can be conveniently transferred to the housing without requiring special turning tools.

Abstract: A jet regulator (1) including a two-part jet-regulator housing (2), the outlet end face (3) of which has multiple passages (4), a pot-shaped inlay (6) that is inserted into the housing interior (2) until it reaches the outlet end face (3) and that has multiple tubular spray nozzles (7), each of which penetrates a passage (4) on the outlet end face of the jet regulator housing (2) and the free spray-nozzle region of which protrudes beyond the outlet end face (3) of the jet regulator (1, 5). The jet regulator also includes an insert (8) that is inserted in the housing interior and the position of the inlay part (6) is secured in an axial direction between the insert, the second housing part and the outlet end face (3).

Abstract: Polyalkeneamines of the formula (I) where R1, R2, R3, R4, R5 and R6 may have different meanings, are prepared by a process in which a polyalkene epoxide is reacted with an amine and the amino alcohol is dehydrated and reduced to give the compound of the formula (I).
