Abstract: A device for opening and closing outlets of a fluid distributor valve includes a body having outlets, and a bonnet housing a rotor submitted to the action of the inflowing fluid and connected to a reducing gear activating the closing device. The opening of the outlets is carried out with respective angularly sliding shutters being turned by successively shifting them in opposite directions to respectively obtain the opening and closing of the outlets. The rotation of the bonnets is determined by lugs below a base bushing bearing, the reducing gear operating on lugs fitted onto the edge of the bonnets.

Abstract: This system is characterized in that it comprises a radio remote control, with transmission protocol, and a modulator-receiver decoding the radio signal and modulating the network voltage to thus transmit the information to the light source being installed inside the spotlight, said modulator-receiver thus controlling the illumination being performed by the diodes (LEDs). This system does as well comprise a transformer being apt to power the light sources with 12 Vac, the modulator-receiver being inserted into the primary winding of said transformer. The light sources rectify and filter the secondary voltage, and by means of two auxiliary diodes they recover the information corresponding to the two half-waves, in such a way that the microcontroller can analyze the half-waves thus detecting those having been trimmed in the primary winding; the transmission protocol decoding the commands and thus allowing the microcontroller to operate the diodes (LEDs) according to the command being received.

Abstract: The invention relates to a swimming pool filter that includes a filter body (1) being formed by a casing (2) with a top cover (3), and the cover (3) forms a water distributor (4), this latter being compartmented (6, 7, 8, 9 and 10), upperly open (11) and provided with lateral openings (12, 13, 14 and 15) for a selected water inflow and outflow, the distributor (4) being closed by a rotatable (24), compartmented (20, 21, 22 and 32) sealing subcover (19). The subcover (19) is apt to be stabilized in its different positions by means of peripheral projections (27) being apt to selectively fit into a socket (28) being integral with the cover (3) in the vicinity of its open top (11). A receiver (32) is inferiorly fitted to the casing (2) and is made up of a grid-like plate conforming to the periphery of the casing (2).

Abstract: The invention relates to an adjustable lamp which can be fitted into a wall such as the, wall of a swimming pool or other water tank the bulb of the lamp can be positioned so that it is parallel to the horizontal, or have with a downward slant, typically between about 3.degree. to about 8.degree.. The lamp can include an elbow duct for receiving electric cables to the lamp. The lamp can be directed in at least eight different angles relative to the point on the wall where these cables reach the lamp by positioning its lighting axis so that it is parallel to the horizontal, or with a downward slant, while the elbow duct for electric cables to the lamp, can be directed in eight different angles, towards the point on the wall where these cables reach the lamp.
