Abstract: An improved filter assembly (1) is disclosed, particularly for electric cabinets, comprising a filter cloth (5), a conveying sump (7) and a fan (9), equipped with at least one thermal-resistive sensor (11) placed next to at least one hole (13) obtained in the conveying sump (7).

Abstract: A pneumatic automation system (1) is disclosed for mobile screens (2) comprising at least one of the mobile screens (2), a device for compressing a control fluid, a device for channeling and checking the control fluid, a device for pneumatically actuating a movement of the mobile screen (2) equipped with at least one sliding cursor (4) controlled by the control fluid and supplied by the compressing device through said channeling and checking means, and a device for connecting the cursor (4) with the mobile screen (2).

Abstract: An anti-condensate resistance (1) with PTC thermistor 5 is disclosed, comprising a central heat sink element (3), such central heat sink element (3) being composed of two dissipating plates (3a, 3b) which are mutually facing and continuously joined in such a way as to form, in a space interposed between the plates, an inserting housing (15) of the PTC thermistor 5 together with a securing element (11), a first and a second closing plugs (7a, 7b) for closing openings of the inserting housing (15) and for hermetically sealing the PTC thermistor 5 inside the inserting housing (15); the dissipating plates (3a, 3b) being equipped with a convex curvature towards their center, each one of the dissipating plates (3a, 3b) being equipped at their ends with inserting tracks (4a, 4b) forming working portions (6a, 6b) on which forces (F) are exerted which are adapted to permanently set joining hourglasses (4c) of the dissipating plates (3a, 3b) for cancelling or reverting the curvature and blocking the PTC thermistor 5 in

Abstract: A pneumatic automation system (1) is disclosed for mobile screens (2) comprising at least one of said mobile screens (2), means for compressing a control fluid, means for channelling and checking the control fluid, means for pneumatically actuating a movement of the mobile screen (2) equipped with at least one sliding cursor (4) controlled by said control fluid and supplied by said compressing means through said channelling and checking means, and means for connecting the cursor (4) with the mobile screen (2).

Abstract: A monodirectional braking mechanism for use with a device for extending and retracting a sheet of material on a roller, the braking mechanism comprising one or more than one housing, one or more than one rotor within the housing, a brake controller connected to the rotor, and an eccentric brake operatively coupled with the brake controller, where the braking mechanism reduces the force or rate, or both the force and rate, of rotation of the roller as the roller is rotated in a second rotation direction but has substantially no effect on the force or rate of rotation of the roller when the roller is rotated in a first rotation direction, and where the first rotation direction is the reverse of the second rotation direction.

Abstract: A screening device with a movable screen and an automating system (1) for mobile screens is disclosed comprising at least one mobile screen (2), guiding means for the movement of the mobile screen (2), compressing means for a fluid, channelling and controlling means for such fluid, internal magnetic elements connected to the mobile screen (2) and external magnetic elements (3) cooperating with the internal magnetic elements.
