Abstract: Connection hinge for spectacles frames of the type adapted to connect the lateral sidearm of a spectacles frame to the front part of the same spectacles frame; the connection hinge being characterized by comprising: a cup-shaped body, which is structured so as to be fixed cantilevered in a rigid manner onto the lateral side of the front part of a spectacles frame, and is provided with a central cavity of substantially cylindrical shape and with a transversal, oblong, pass-through slot or cut, which extends along the lateral side of the cup-shaped body while remaining on a lying plane locally substantially perpendicular to the reference axis of the central cavity, and penetrates in the cup-shaped body up to said central recess; a central pin which has a cylindrical shape substantially complementary to that of the central cavity of the cup-shaped body, and is inserted in axially rotatable manner in the central cavity of the cup-shaped body; and a transverse locking plug which has an end rigidly fixed to the bod

Abstract: A domotic system (1B) for the centralized drive, control and management of domestic appliances, devices, apparatuses, installations (4.1 . . . 4.n) existing in a dwelling-house, consisting of a logic unit (2) of remote drive, control and management and a plurality of the apparatuses, devices and installations (4.1 . . . 4.n), characterized in that the apparatuses, devices and installations (4.1 . . . 4.n) are provided each with wireless communication elements (20) by which they are remote driven, controlled and managed by the remote logic unit (2) which is also provided with its own central wireless communication elements (23).

Abstract: The device comprises, for each selector element, a high-speed electromagnet having a fixed core with a single coil, and an armature consisting of a lightweight blade. When the coil is energized, the blade is moved into one position, and is restored to another position by means of a compression spring when the coil is de-energized, with a response time of less than 4 ms. The electromagnets are housed in the support of a selection assembly, and packed in at least two offset rows. Each coil is energized at a first voltage and is subsequently maintained energized at a lower voltage.

Abstract: A solenoid valve comprising an inlet conduit coaxial with an exhaust conduit; and an on-off element supported on the anchor of an electromagnet and moving substantially along the common axis of the two conduits for alternately connecting the inlet conduit and the exhaust conduit to an outlet conduit via a connecting compartment. The anchor normally closes the inlet conduit via flexible means, such as a permanent magnet in the magnetic circuit of the electromagnet, magnetized the opposite way to when the electromagnet is energized. The action of the electromagnet is such as to substantially eliminate that of the magnet on the anchor, which is thus set rapidly to the closed position over the exhaust conduit.

Abstract: A solenoid valve having an electromagnet arranged in a chamber into which an inlet duct and an outlet duct of the solenoid valve open, whereby the coil is constantly ventilated by the compressed air itself. The armature of the electromagnetic has a disc for shutting off the outlet duct and is formed by a plate which is urged into the closed position of the solenoid valve by the compressed air. The plate rotates about a beading of elastomeric material and exhibits extremely low inertia, whereby the solenoid valve can be operated at high frequency. The chamber can house a plurality of electromagnets, each of which controls a shut-off member for a corresponding outlet duct. The body also comprises an interchangeable shell which has funnel-shaped chambers for directing the air of at least one set of ducts to a common outlet aperture.
