Abstract: A safety system for a battery-powered fog generator is described, designed to operate on a vaporization coil (2) of a fogging fluid; the safety system includes: a fuse wire (1), each placed at one end of the coil (2), suitable for heating both due to a Joule effect and through heat coming from the coil (2) by thermal conduction, the fusible wire (1) being therefore designed to melt when its temperature exceeds a melting threshold value, interrupting the power supply from the battery to the coil (2); a sensor (6) designed to detect the temperature of the coil (2) when current flows in it; and a control unit (7) operatively connected to the sensor (6).

Abstract: A fog-generating system (1) is described, comprising: a tank (5) containing fog-generating fluid; a pump (3) connected to the tank (5) to withdraw the fog-generating fluid therefrom; a serpentine (2) connected to the pump (3) to receive the fog-generating fluid pumped by the pump (3), the serpentine (2) being divided into a first section (A) connected to the pump (3) and a second section (B) connected to the first section (A) and designed to emit dry fog (7) as output; a battery (6) connected to the serpentine (2) to pass electric current inside the serpentine (2) and to supply the pump (3); a differential amplifier (11) connected to the second section (B); and a threshold comparator (13) which, upon exceeding a certain voltage, a stop index of the serpentine (2) in the second section (B), breaks the supply to the pump (3).

Abstract: A quick-disconnecting device (1), in particular for kite-surf, comprising a fixed element (3) and a moving element (5) having an operating connecting position in which the moving element (5) is kept integral with the fixed element (3) by interposing a blocking system (7), and an operating disconnecting position in which the moving element (5) is disengaged from the fixed element (3) by actuating the blocking system (7), such moving element (5) being equipped with a first connecting end (9), of a terminal (21) of a connecting element to by actuating the blocking system (7), such moving element (5) cooperating with the fixed element (3) through a lever-type dynamics around a fulcrum point (F) interposed between the moving element (5) and the fixed element (3), such device (1) further comprising an automatic fastening system (40) of the moving element (5) to the connecting element.

Abstract: A monodirectional braking mechanism is disclosed, 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 containing viscous fluid, one or more that one rotor within the housing; a brake connected to the rotor and placed within the housing, the brake comprising a projecting pin; a braking spring wound around the pin of the brake and placed outside the housing; 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.
