Abstract: Hydraulic actuating device (1) for actuating a water evacuation mechanism (2), includes: an actuating unit (4) with plunger(s), a control unit (5) that can be integrated with the actuating unit, at least one three-way hydraulic valve (6) supplied by a water distribution system and controlled by the control unit (5), and at least one single-action hydraulic jack (3) supplied via the valve and ensuring the triggering of the water evacuation mechanism by raising a closing flap (56) or a plug.

Abstract: A flushing mechanism for toilet tank comprises an overflow tube (1) provided with a sealing valve (3, 4) co-operating with a discharge orifice (5?) including a first floater (30) mounted on a height-adjusting screw (31) and a second floater (40) mounted pivoting about a fixed pin (41). The adjusting screw (31) is articulated (33) on a lever (34) articulated about a fixed pin (35), the lever (34) is provided with a snug (36) co-operating with a first locking cam (37) and the second floater (40) is provided with a snug (42) co-operating with a second locking cam (43). The invention is applicable to double-volume flushing systems.

Abstract: The invention concerns a flushing mechanism for toilet tank comprising an overflow tube (1) provided with a sealing valve (3, 4) co-operating with a discharge orifice (5′) including a first floater (30) mounted on a height-adjusting screw (31) and a second floater (40) mounted pivoting about a fixed pin (41). The invention is characterised in that the adjusting screw (31) is articulated (33) on a lever (34) articulated about a fixed pin (35), the lever (34) is provided with a snug (36) co-operating with a first locking cam (37) and the second floater (40) is provided with a snug (42) co-operating with a second locking cam (43).

Abstract: An attachment for supplying a filler wire to an electric soldering iron of the pen type includes an independent support butt having an upper housing provided with a V-shaped groove defined by two lateral faces of a dihedron. The cylindrical body portion of a pen type soldering iron is received in the groove and fixed therein by a flexible, length adjustable clamp passing around the body and having its ends fastened to the butt so as to maintain the body tangentially to the faces of the dihedron so that it forms a unit with the butt. The adjustable clamp permits soldering irons whose bodies are of different diameters to be immobilized in the groove. The support butt is provided with a manually operable trigger actuated mechanism for incrementally feeding and guiding a length of filler wire toward the heated tip of the supported soldering iron during use. The power supply lead for the electric heating element of the electric soldering iron extends through a passage in the support butt.
