Abstract: A rigid-walled, block-shaped box is internally provided with a compartment arranged adjacent to a vertical wall of the box and having a first chamber with a first window open to the inside of the container and a second window open to the outside, and a second chamber with a third window open to the inside of the container and a fourth window open to the outside. The windows are each provided with a shutter. A mass of phase change material is housed within the compartment between said first chamber and second chamber, for absorbing heat from the air flowing from one chamber to the other chamber when said first window and third window are open and said second window and fourth window are closed, and releasing heat to the air flowing from one chamber to the other chamber when said first window and third window are closed and said second window and fourth window are open.

Abstract: The semitrailer is joinable to a tractor provided with a vertical towing gudgeon, is supported at its back end by a wheeled structure, and comprises a chassis having longitudinal members and crosspieces, which define a horizontal loading platform, and further having uprights rising from its forward end. A towing bar is hinged on the uprights around a first horizontal and transversal hinging axis. A compensating hydraulic cylinder is articulated between the chassis and the towing bar. A coupling is articulated to the towing bar forwardly of the first axis, for hinging around a second horizontal and transversal hinging axis, and is provided with a bushing that is transversal to the second hinging axis and is rotatably engageable on the towing gudgeon of the tractor.

Abstract: An apparatus that can be bolted to the transom of a vehicle, comprising in combination a central box, which is open on at least the part of the surface that faces the transom of the vehicle and forms an extension for increasing the carrying volume and the buoyancy. Two lateral elements, for flotation and support of hydraulic propulsion motors with ducted propeller, are connected to the central box and contain respective fuel tanks and reservoirs for the motor actuation fluid, and there are ducts that end on the surface that faces the transom of the vehicle and are preset for the output, return and drainage connections of the motors.

Abstract: An amphibious vehicle comprising: a chassis (10), which has a hull-like structure and comprises supporting wheels (11) and driving wheels (13-14) for tracks (12) of the rubber-clad type, a fore buoyancy reserve (21) and an aft buoyancy reserve (22) which are obtained by means of a corresponding fore element (21′) and aft element (22′) which are permanently applied by means of watertight welds (CS) to the chassis. A power plant (MP) comprises an internal-combustion engine and two hydraulic pumps (41′-41″) which, by virtue of corresponding delivery circuits (42′-42″), feed first hydraulic motors (44′-44″) for simultaneous or selective driving of tracks for propulsion and steering on land and second hydraulic motors (45′-45″) for simultaneous or selective rotation of hydrodynamic propulsion and steering propellers.

Abstract: The gear comprises at least two auxiliary flotation sections, respectively a forward section and a stern section, which can be detachably associated with the hull of the vehicle, each section being constituted by a profiled metal container. The forward section has immersed surfaces which are profiled so as to produce lift for hydrodynamic support, and the stern section includes two thrust propellers of the ducted type, arranged symmetrically with respect to the longitudinal centerline plane of the vehicle; auxiliary motor means being provided in order to simultaneously or selectively turn said propellers both for propulsion and for steering.
