Abstract:
The stabilising device for boats comprises two propulsion units (2) emerging from a hull of the boat and positioned on opposite sides of a boat longitudinal axis (A3), each of the propulsion units (2) comprising a fin (3) and motor means for rotating the fin (3) both about its first axis (Al) of longitudinal extension, and about a second axis (A2).
Abstract:
An optical device (1) for indicating the glide angle of aircraft comprises at least one light source (2) of predetermined colour, at least one unit (4) for creating a light image, coinciding with the light source (2), and at least one unit (5) for projecting the light image at a distance. The light source (2) comprises an electroluminescent light panel (3).
Abstract:
A vehicle with at least two wheel axles comprises a folding frame having an "inverted V" shape on a longitudinal-vertical plane (X-Z) comprising a first rear arm (11) and a second front arm (12) merged in a upper intersection portion (13), the end (12a) of the second arm (12) being coupled to a front steering tube (14) with a substantially vertical axis or with a slight tilt toward the intersection portion (13) of the "inverted V" and tilted with respect to the second arm (12) so as to define an angle with it on the longitudinal-vertical plane (X-Z), wherein a transverse axis joint (17) is placed at the intersection portion (13) of the two arms (11,12), wherein the first (11) or the second arm (12) has an extension beyond the intersection portion (13) defined by a section (1 1 c) of the arm whose free end is coupled to a saddle (110) of the vehicle and wherein the first arm (11) is intended to support and discharge to the ground at least part of a vertical load weighing on the saddle (110).
Abstract:
Described is a visual indicator device for landing aircraft (2) on the deck (3) of a ship (4), comprising a unit for measuring the instantaneous rolling motion angle of the ship (4), a light projection apparatus (6) designed to project, on a non-horizontal wall (5) of the ship (4), at least a first rectilinear segment (7) representing the horizon line.
Abstract:
Described is an apparatus for sweeping influence mines, comprising an operating unit (2) having a plurality of propulsion devices (8) designed to be immersed in water and at least one floating body connected to the propulsion devices (8), the latter being designed to overcome the hydrostatic thrust acting on the floating body to keep the operating unit (2) immersed at a predetermined depth.
Abstract:
Described is a system for neutralising underwater explosive devices comprising an apparatus for identifying a naval mine (4), a source (8) for emitting an acoustic signal for signalling the position of the naval mine (4), a first underwater vehicle (5) designed to place the source (8) for emitting an acoustic signal (9) close to the naval mine (4), a measurement apparatus designed to determine a first distance (Rs) between the source (8) of emission of an acoustic signal and the naval mine (4).
Abstract:
Described is a lighting system for aircraft landing surfaces (2), comprising a plurality of electric lighting elements (3) arranged in an orderly sequence to help to form on the surface (2) a predetermined symbol (R1, R2), visible from the aircraft during landing, at least one branch box (7) for accessing the electricity network, the sequence of the lighting elements (3) forming a chain (6).
