Abstract: The invention relates to a protective sheath comprising an assembly of at least one electrically non-conductive thread, referred to as a core thread, which contributes to the final shape given to the sheath, and electrically conductive threads, as well as at least one protective film combined with all or part of one of the surfaces of the sheath, and characterized in that the protective film is combined by welding. Such assembly of the film by welding and not sewing ensures that the sheath is not damaged during its manufacturing.

Abstract: An inflatable body includes an elongate chamber delimited by two substantially parallel main walls and defining at least a portion of a base suitable for holding a person laid down thereon, the chamber being extended, integrally, on both sides of the base, beyond a transition area where the main walls are close to each other, by two raised lateral strips extending along at least the base portion, so as to laterally flank the person, wherein the main walls are braced by a plurality of drop stitch links, and at the location of the transition area, the inflatable body has seams bringing the main walls together, thereby causing a fold between the base and each of the raised lateral strips, with the seams being covered by a sealed lining wall.

Abstract: The safety device comprises a first bridle connecting a pilot chute of the reserve parachute to a deployment bag, a second bridle connecting the main parachute to the first bridle, a pin fastened to this first bridle and passed in a releasable manner in a loop formed on a locking bridle fastened to the locking pin and passed through a loop fastened to the second bridle and two eyelets formed through the first bridle.

Abstract: A pilot chute device is connected to a parachute canopy for deploying the parachute canopy out of a container adapted to be closed and opened and within which the parachute canopy is foldable. The pilot chute device includes an inflatable pilot chute adopted to assist the deployment of the parachute canopy, the inflatable pilot chute being foldable into the container, and a spring device adopted to push the inflatable pilot chute outside the container when the container is opened. The spring device is dispensed apart from the inflatable pilot chute, between the pilot chute and the parachute canopy.

Abstract: A tank capable of containing a liquid has a first volume (21) capable of containing the liquid (22), the first volume (21) having at least one opening (23) initially sealed by a first wall (24) and the first wall (24) being capable of being retracted when a pressure exerted thereon exceeds a specific threshold. The tank further has a second flexible wall (30), sealing said opening (23) in a sealed manner when the first wall (24) is retracted and capable of being deployed, via said opening (23), after the retraction of the first wall (24), in order to provide the liquid with a volume that is greater than the first volume (21).

Abstract: A method of assembling a de-icing mat (3) on a piece of wing structure (1) includes shaping a shielding foil (2) so that the internal surface (5) thereof has a shape that complements the external surface (6) of the piece of wing structure (1). The method then includes securing the de-icing mat (3) to the internal surface (5) of said shielding foil (2), leaving a surface uncovered with the de-icing mat on the contour (8) of the shielding foil (2) to allow direct contact between the contour (8) of the shielding foil (2) and the piece of wing structure (1) in a contact region (7) thus created. The method then includes attaching the shielding foil (2) to the piece of wing structure (1) at the contact region (7), and injecting a filling resin (4) between the de-icing mat (3) and the piece of wing structure (1).

Abstract: The present invention relates to a composite pipe (1) designed to transport, indiscriminately, a hydrocarbon fuel or a hydraulic fluid, characterized in that it comprises a hollow central sheath (10) made of a thermoformed thermoplastic and an external sheath (20) consisting of several radially superposed layers (22, 24) comprising at least one layer of resin (24) placed in direct contact with the central sheath (10) and one layer of fibers (22) covering the layer of resin (24).

Abstract: Method for assembling de-icing matting (3) and an external protective metal shield (2), on a structure (1), such as an airfoil leading edge structure (1), comprising the following steps: manufacture of de-icing matting (3) independent of said structure (1), installation of the de-icing matting (3), between said structure (1) and the metal shield (2), said de-icing matting (3) covering only a portion (4) of the external surface of said structure (1), attachment of said metal shield (2), entirely covering said de-icing matting (3), to the portion (5) of the external surface of said structure (1) not covered by said de-icing matting (3).

Abstract: The invention concerns a laminate comprising a conductive fabric web (2) consisting essentially of electrically conductive material fibers, said web is provided with a terminal (2) designed to be connected to an electric current source, being sandwiched between an upper reinforcing layer (3) and a lower reinforcing layer (1) consisting each of an electrically insulating material. Said laminate is characterized in that said upper (3) and lower layers (1) comprise each an elastomer. The invention also concerns an electrothermal deicer comprising said laminate sandwiched between two protective coatings (5, 6), one of said coatings being optionally covered with a metal foil (8).

Abstract: A device is disclosed for self-sealing connection between containers having a flexible wall bearing on a rigid (1) or thin (1') partition, through which passes a connecting sleeve (3) having a fold inside the container, which a tractive force separating the containers seals, before breakage of the cylindrical barrel (6), by means of a jamming element (9, 13), after causing the fold (5) to turn back over the orifices of a tube section (10).

Abstract: A parachute canopy comprises air entries provided on the canopy itself. The canopy is constituted by an assembly of gores, each gore being composed of three gore portions. The air entries are provided on a predetermined number of gores, the medium gore portion overlapping the lower gore portion. The medium gore portion and the lower one are sewn together only at meridional lines such as to leave a free passage between their overlapping portions which constitutes an air entry.
