Abstract:
Described is a device for introducing an air flow (F) into a submarine (1), comprising a first duct (3) which is fixed relative to the hull of the submarine and a second duct (4) which is telescopically movable relative to the first duct (3), for emerging from the water with its upper end (4a) and allowing the air above to be sucked in while the submarine (1) is running at periscope depth, the first and second ducts (3, 4) being in fluid connection with air sucking means and being at least partly housed in a tower (5) of the submarine.
Abstract:
A naval azimuth propulsion system including an electric motor, a propeller operatively connected to the electric motor to rotate about a relative central axis, an annular nozzle positioned coaxially around the propeller, elements for supporting the motor and the propeller, these elements being connectable to the hull of a ship, first magnetic shielding means designed to shield the magnetic field generated by the electric motor during its operation.
Abstract:
An antenna for submarines comprises a base member (2) extending along a main direction of extension (B) between its bottom end (2a), which is fixable to a structure of a submarine (100), and its top end (2b), at least one movable stem (3), juxtaposed with the base member (2) and extending along the main direction of extension (B) between its bottom end (3a) and its top end (3b), electrical connection means (6) between the stem (3) and the base member (2) and movement means (5) by which the stem (3) is moved relative to the base member (2) along the main direction of extension (B) between a lowered position and a raised position. The connection means (6) comprise a wire-shaped element (7) extending between two end portions (7a, 7b) connected to the stem (3) and to the base member (2), respectively, where at least the end portion (7a) connected to the stem (3) is equipped with an underwater connector (9).
Abstract:
A surface mounting lamp comprises a covering element (3) made of a transparent material and having a first face (3a), which in use is directed outwards away from a mounting surface of the lamp, and a second face (3b) opposite the first face (3a) and provided with at least one socket for housing lighting elements (2a), at least one lighting unit (2) sealably connected to the covering element (3) and facing the inside of the socket. The unit (2) is equipped with a plurality of lighting elements (2a), each housed in the socket. The lamp also comprises at least one junction piece (8) connected to the covering element (3) and equipped with a connecting portion (8a) which can be engaged with the mounting surface of the lamp in order to fix the position thereof, and retaining means interposed between the junction piece (8) and the second face (3b) of the covering element (3) and operating in such a way as to connect the covering element (3) to the junction piece (8).
Abstract:
Hydraulic motor with propulsion members (10) positioned between a cam (3) associated with a shaft (2) and a reaction element (1b), said propulsion members (10) consisting of two elements (11,12), i.e. an internal element (12) and external element (11), telescopically slidable with respect to each other in a radial direction and respectively provided with annular bearing edges (11a,12a) kept pressed against corresponding contact surfaces (3a,1a) of said cam (3) and said reaction element (1b) via respective resilient means (16), the resilient means associated with the external element (11) of the propulsion member being arranged outside the said element, characterized in that the resilient means (16) associated with the internal element (12) are arranged inside the propulsion member (10) and positioned in the radial direction between said internal element (12) and associated means (52,55) for mechanically retaining them.
