Abstract: A firearm support system is adapted to be installed in a vehicle, in particular an aircraft. The vehicle includes a compartment to accommodate the crew. The compartment has: a bearing surface, an upper structure rising above the bearing surface, and an opening, through which a firearm shoots. The support system includes: an anchoring portion, for being fixed to the upper structure and located in the compartment; a mobile support, which is coupled to the anchoring portion in a mobile manner, is adapted for receiving the firearm, and allows the firearm to move between an operating position, in which the firearm is ready to shoot through the opening, and a non-operating position, in which the firearm is retracted.

Abstract: A firearm support for a firearm includes: a body, which is provided with at least one profile on its surface; a feeler pin, for striking against the profile and for being coupled to the firearm so as to follow the movement of said firearm; a support element, rotatable around a first axis (z-z) relative to the body. The support element is suited to be coupled to the firearm, thus allowing mutual rotation between the support element and the firearm around a second axis (x-x).

Abstract: The method allows to monitor a composite material comprising an epoxy resin filled with electrically conductive nanoparticles, wherein at least one electrical property i.e. impedance of the composite material is influenced by being subjected to a mechanical deformation. The method provides for inserting the composite material in an electric circuit emitting an electric signal whose value depends on the electrical property, so that, when the value of the signal overcomes a given threshold value, a warning message is delivered.

Abstract: Disclosed herein is a method for applying a conformal coating to one or more radio frequency elements of an antenna or antenna array. Said method is characterized in that the conformal coating is based on a thermoplastic material produced from a mixture comprising a thermoplastic polymer and an olive pomace.

Abstract: The system comprises at least one evaporator device arranged around a tube inside which a hot fluid flows and, for each evaporator device, a respective conduit connected at its opposite ends to the evaporator device so as to form with the latter a closed circuit containing a two-phase fluid. Each evaporator device comprises a casing, having an inner wall in contact with the respective tube and an outer wall enclosing a cavity with the inner wall, and a separating member of porous material arranged inside the casing so as to divide radially the cavity into an inner cavity, extending between the inner wall and the separating member, and an outer cavity extending between the separating member and the outer wall.

Abstract: A sealing ring for a seal assembly is described that comprises: a main body rotating about an axis; and a first surface, which is defined by the main body, extends transversely to the axis and is suitable for abutting against a further sealing ring in a direction parallel to the axis; the first surface comprises a plurality of grooves forming respective hydropads; the grooves are delimited by a first edge and a second edge facing one another; the first edge and the second edge delimit the grooves in a circumferential direction to said axis; at least one of the first edge and the second edge is shaped like an elliptical arc, which has coincident or separate foci; comprises first grooves and second grooves alternating with one another in a circumferential direction to said axis and staggered from each other in a radial direction to said axis.

Abstract: A method of making a tubular casing for an underwater device, wherein a metal ring made of aluminum is subjected to an anodizing process that produces an insulating layer of aluminum oxide that covers it externally. The ring is coupled with a mold that defines a cylindrical surface on which the following are deposited: first layers of carbon fiber to produce a first cylindrically-shaped tubular element in carbon fiber provided with an end portion that engages a first groove of the ring; a layer of syntactic material configured to transfer radial forces; and second layers of carbon fiber to produce a second cylindrically-shaped tubular element in carbon fiber that covers the syntactic layer and is provided with an end portion that engages a first groove of the ring.

Abstract: A structural element of a means of transport comprising a resistive heater for defrosting operations, wherein the resistor has conduction terminals coupled to respective terminals of a voltage generator adapted to cause a current flux through the resistor. The resistor includes one or more conductive paths of partially reduced graphene oxide or partially oxidized graphene configured to generate, when travelled by the current flux, heat by Joule effect.

Abstract: A wheel drive cart for a transporting and/or sorting system configured to tow a plurality of loading carts movable along a closed path, constituted by a first and a second rail parallel to each other, between a loading and unloading stations. The cart includes a pair of direct drive wheels without reducers, with each wheel including an electric motor having a stator, integral with a bracket hinged to a frame of the cart, and a rotor, a peripheral outward facing portion of which forms a cylindrical surface of the wheel designed to roll on a resting surface of a respective rail.

Abstract: A transportation system for objects, wherein a train formed by a plurality of carriages moves along a rail and transports objects, for example parcels. The train comprises first carriages, each of which is provided with a pair of first motor-driven rectilinear belts, arranged with their longer edges mutually parallel and perpendicular to the direction of feed of the train.
