Abstract: The driving mechanism has a tubular housing coupled to a control valve and housing an activating cylinder and an activated cylinder, cooperating with each other and respectively coupled to a rod of a wheel and a sealing device. The driving mechanism presents: an inoperative condition, in which the activated cylinder is maintained in a closing position of the control valve; a first operative condition, obtained by the rotation of the activating cylinder in a first sense and in which the activated cylinder is maintained in a first opening position, until the activating cylinder is rotated in an opposite sense, returning the activated cylinder to its closing position; and a second operative condition, obtained by rotation of the activating cylinder in a second sense and in which the activated cylinder reaches a second opening position, from which it is automatically displaced back to its closing position, in a timed manner.

Abstract: The faucet comprises a body having a cold water inlet, a hot water inlet and a service water outlet, and housing a monocontrol mechanism, for blocking and liberating the communication between the cold water inlet and/or hot water inlet with the service water outlet; a tubular column, coupled to the body and open to the service water outlet, and onto which is mounted a first head carrying a service radial spout connected to the service water outlet; a filter cartridge mounted in the interior of the tubular column, inferiorly connected to the cold water inlet and onto which is mounted a second head which carries a filtrate radial spout connected to the outlet nozzle of the filter cartridge; and a filtrate cock for blocking and liberating the fluid communication between the cold water inlet and the filtrate radial spout.

Abstract: A process for engraving metal plates to be used as patterns for texturized products, in which the pattern to be reproduced is formed on a silk screen, the pattern formed on the screen is transferred to the previously roughened surface of the metal plate to be engraved by an acid-resistant paint, and the metal plate is subjected to electro-erosion in an inorganic acid bath, using as one electrode the metal plate itself, and as another electrode a plate of the same material or another material. When different engraving depths are required, the process is interrupted, with the already engraved portions being covered with the acid-resistant paint, and the uncovered portions being subjected to an electro-erosion engraving, this sequence being repeated until obtaining all depths required in the pattern desired.
