Abstract: A magazine floor plate for a firearm magazine includes sidewalls that extend vertically from floor plate and define an interior cavity for accommodating a portion of the firearm magazine. The sidewalls include a first parallel longitudinal sidewall, a second parallel longitudinal sidewall, a first parallel traverse sidewall, and a second parallel traverse sidewall. The magazine floor plate further includes a locking mechanism for insertion between the firearm magazine and at least one of the sidewalls when the interior cavity accommodates the portion of the firearm magazine. The first and second parallel longitudinal sidewalls have a length greater than the firearm magazine.

Abstract: An antifreeze system for a pipework, the antifreeze system comprising a framework configured to be fixed to the pipework, and at least one thermally insulating sleeve maintained around the pipework by the framework. Each sleeve is configured so that a space is produced between the sleeve and the pipework. The framework has an inlet and an outlet which are configured to produce a fluid communication between the outer side of the antifreeze system and the space. The inlet is fluidly connected to a source of hot air. Such an antifreeze system thus enables a flow of hot air around the pipework which thus prevents the liquid which flows therein from freezing.

Abstract: An aircraft with a landing gear, a compartment to stow the landing gear and doors for the compartment movable between an open position and a closed position. The movement of the doors is controlled by a maneuvering system having two transmission chains or linkages each connecting one of the doors to an actuation member that includes a rotatable arm and an actuating cylinder. Each transmission chain or linkage has a relay element mounted pivotably on a structural element of the aircraft, a first connection element between the arm and the relay element, and a second connection element between the door and the relay element.

Abstract: An aircraft comprising a first door and a second door, each being mobile between an open position and a closed position, and a maneuvering system. The maneuvering system includes an actuation mechanism, a first transmission chain configured to transmit the movements of the actuation mechanism to the first door, a second transmission chain configured to transmit the movements of the actuation mechanism to the second door. Such a maneuvering system uses a single actuation mechanism, which results in a simplification of the mechanism and a weight saving.

Abstract: A cover plate, to cover part of a space between a door and a door surround, comprising at least one pressure element secured to at least part of the external face of the cover plate. The pressure element comprises two sheets, an external sheet and an internal sheet, these two sheets being superposed and fixed together. The internal and external sheets are respectively made from materials that have different thermal expansion properties causing at least a contraction of the internal sheet with respect to the external sheet, at least for a range of temperatures comprised between ?20° C. and ?50° C.

Abstract: A routing support (64) for a conduit line fastened in openings and the line includes a plurality of conduits connected end-to-end along a longitudinal axis. The routing support (64) incorporates an outer body (66) with a structure (68) for fastening the body in an opening. The routing support also includes a housing structure to accommodate the ends of two conduits in an end-to-end arrangement and the structure may include two separate structures (one for each conduit end (72)) or a single common structure (accommodating respective ends of the two conduits). The routing support also includes a flexible interface (74) connecting the housing structure (70) to the outer body (66). In addition, the flexible interface (74) and the outer body (66) and the housing structure (70) are integral. Embodiments include a line for transporting fuel with this routing support, and an aircraft wing in which such a line/support transports fuel.

Abstract: A movable panel such as an aileron is connected to a load-bearing structure such as a wing of an aircraft by hinges which comprise flexible, elastic plates which are juxtaposed and are provided at opposite angles so as to allow the panel to rotate in an easy manner in response to the movements of an actuator; the hinges are, however, rigid in regard to other loads, such as aerodynamic suction loads, such that inadmissible travel of the panel is avoided.

Abstract: A connection device for a releasable conduit including an end piece of a first conduit, a ring nut capable of being joined while in use to a locking ring of the releasable conduit, the ring nut being integral with the end piece. According to the disclosure herein, an auxiliary element is movably mounted on the end piece between a retracted position (PR) and an extended position (PS), so as to alter the axial length of the first conduit. The disclosure herein likewise relates to a pipeline for the circulation of a fluid, in particular fuel, including a connection device of this kind.

Abstract: An internal pulse damper for use in a fuel rail for an internal combustion engine. The damper is formed from a length of tubular metal stock having a flat oval cross-section and ends flattened by crimping to form a captive-air pillow. The end crimps are improved through use of tooling to eliminate a creased sidewall area vulnerable to stress failure in prior art pulse dampers.
