Abstract: A device for introducing an air flow into a submarine, including a first duct which is fixed relative to the hull of the submarine and a second duct which is telescopically movable relative to the first duct, for emerging from the water with its upper end and allowing the air above to be sucked in while the submarine is running at periscope depth, the first and second ducts being in fluid connection with air sucking means and being at least partly housed in a tower of the submarine.

Abstract: A surface mounting lamp includes a covering element of a transparent material and having a first face, which in use is directed outwards away from a mounting surface of the lamp, and a second face opposite the first face and provided with at least one socket for housing lighting elements. A lighting unit is sealably connected to the covering element, facing the inside of the socket and includes a plurality of lighting elements, each housed in the socket. The lamp also includes a junction piece connected to the covering element and having a connecting portion engageable with the mounting surface of the lamp to fix the position thereof, and a retaining mechanism interposed between the junction piece and the second face of the covering element and connecting the covering element to the junction piece.

Abstract: Apparatus for moving supports carrying sensors displaceable inside fixed guides integral with the towers of submarines, and the like, upon operation of an actuator, the actuator consisting of an electric motor coupled to one end of a screw actuator on which a screw nut integral with a rod is movable, the entire assembly being contained inside a housing with seals, from which the free end of said rod protrudes for fastening to the tube. The housing can include a first bearing and a second bearing or bushing for supporting the rod and the screw actuator coaxially within the housing. The housing can include a top chamber above the first bearing and a bottom chamber below the first bearing. One or both of the chambers can be filled with lubricating oil to dissipate heat and/or dampen noise. The bottom chamber can house the motor and include a dielectric oil. The motor can be controlled by an electronic actuating system using an angular position transducer.
