Abstract: In a toilet comprising a toilet bowl, the water-saving system comprises a first emitter for emitting a first beam having a first wavelength comprised between 300 and 495 nm. A second emitter for emitting a second beam has a second wavelength comprised between 590 and 900 nm, at least one detector for receiving the first and second beams. The first emitter, second emitter and detector(s) are installed on the toilet such that the first beam and second beam pass through the water contained in the toilet bowl before being received by the detector(s). A controller receives and processes data from the detector(s), and the data representing the waste level in the toilet bowl. A flush volume actuator is actuated by the controller for flushing a variable volume of water as a function of the data, so as to minimize the volume of water.

Abstract: Method of producing a preform for thermoformed containers, which takes the form of a token. The method includes the following steps: producing the lower part (3) of the token, this step including the extrusion of a cylindrical bar (2) and the cutting of the bar (2) into disks (3); producing the upper part (6) of the token; and assembling the two parts by heat sealing.

Abstract: A self-adjusting control device for a flushing system mechanism borne by a stirrup and provided with pivoting arms actuated by fingers borne by pull-handles for flushing the water, the water flush control being provided via rods acting on the head of the pivoting arms, by externally accessible control knobs on the water flushing apparatus lid. The device comprises: a housing (16) containing the control knobs (19, 20), provided with a thread pitch (p1); an insert (14), integral in rotation with the housing (16) provided with a thread pitch (p2); a fitting (25) borne by the insert (14) carries the pivoting axis (26) of the arms (10, 11); the thread pitches (p1, p2) are in the ratio p1/p2 =L1/L2 of the vertical projections of the distances from the axis of the finger (33, 34) (L1) to the contact points (31, 32) of the heads (29, 30) of the arms (10, 11) and the rods (21, 22), and (L2) to the pivoting axis (26) of the arms (10, 11).

Abstract: Multilayer sheet for making containers with lid closed by sealing.The upper layer 7 is comprised of an heterogeneous mixture of two products having different coefficients of viscosity, the most fluid product being compatible with the lower layer 8 of the lid.Removal of the lid leads to tearing of the upper layer 7 by decohesion.

Abstract: The invention relates to a device for the actuation of the valve of a flush tank: a movable vertical tube (8) carries a valve (7). A linking rod (9) controls the movement of the tube, a lever (12) operates the linking rod, a member (16) operates a rod (15), which in turn controls the lever (12). The rod (15) is connected to the lever (12) and to the operating member (16), the operating member having two positions, one being the opening position (26), and the other one being the closing position (27), and the passage of the member from one to the other one of these positions, controlled by the user, bring about the correlative passage of the valve (7) from one (26") to the other one (27") of the positions and inversely.

Abstract: Process designed to obtain a sheet of thermoplastic material containing at least on one side a decoration consisting of parallel stripes of different colors juxtaposed to each other and capable of being thermoformed to produce hollow volumes containing the same initial decoration, characterized in that it consists in extruding simultaneously, through a single multiple duct die, firstly a monochrome basic layer, secondly at least one intermediate decoration layer, formed of longitudinal, juxtaposed stripes of different colors, and lastly at least one upper transparent layer overlapping said intermediate layer, all said layers being combined in a die area as close as possible to its outlet.

Abstract: An element adapted to engage a rod is composed of a tough synthetic-resin material and is tubular so as to receive the rod. Relatively long slots opening at one end of the element are aligned with relatively short slots opening at the opposite end of the element so that the opposite end of the element is formed with jaws which can be spread apart when members defined between the long slots are pressed together in a pincer movement. The inner surfaces of the jaws are provided with formations engageable with complementary formations on the rod.
