Abstract:
An apparatus for sweeping influence mines, including an operating unit having a plurality of propulsion devices designed to be immersed in water and at least one floating body connected to the propulsion devices, the latter being designed to overcome the hydrostatic thrust acting on the floating body to keep the operating unit immersed at a predetermined depth.
Abstract:
A lighting system for aircraft landing surfaces, including a plurality of electric lighting elements arranged in an orderly sequence to help to form on the surface a predetermined symbol, visible from the aircraft during landing, at least one branch box for accessing the electricity network, the sequence of the lighting elements forming a chain.
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 guided lifting system, comprising: a lifting unit (20), installable on a loading deck (S) and configured to exert a lifting force that has at least one vertically directed component; a pick-up module (101), associated with the lifting unit (20) and configured to hook a vehicle (3) to be lifted; characterised in that: it comprises a guide device (10), connected to the pick-up module (101) and configured to move the pick-up module (101) in space in a guided manner; the guide device (10) can be actuated and controlled autonomously from the lifting unit (20).

Abstract:
A guide apparatus for supports (20) for sensors (30) able to move by translation in fixed guides (10) integral with the sail (Ia) of submarines (1) and the like upon activation of an actuator (40), where the fixed guide (10) has a polygonal cross-section, at each vertex (10b) of the guide (10) there being at least one structure with the shape of a prism (11) extending in the vertical direction (Z - Z) along the entire body of the guide, the prismatic elements (11) extending towards the inside of the guide (10) in such a way as to form at least two sliding surfaces (12) for corresponding sliding blocks (22) belonging to the tube (20) to be moved by translation.
