Abstract: A drainage valve comprising a through hole, a seat around the through hole, a shutter comprising an end face and movable in a longitudinal direction between a first position in which the end face of the shutter is away from the seat and a second position in which the end face of the shutter is pressed against the seat and blocks the through hole, and an elastic element configured to keep the shutter in the first position. The shutter has a recess, emerging at its end face, configured to introduce therein a part of a tool in order to temporarily secure the part of the tool and the shutter in order to displace it in two directions longitudinally.

Abstract: A seal includes a barrel extending between a base and a top, in which the barrel has a cylindrical cavity passing through it between its base and its top, and a skirt indissociable from the barrel and extending around said barrel, in which the skirt adopts the shape of a dome of which the exterior edges extend out beyond the base starting from the top. The seal is able to divert the fluid and keep the space under the skirt fluid tight.

Abstract: A sleeve fastening system fastened to a joist pierced with a hole and receiving two pipes and including a cylinder fitted into the hole of which each end receives a pipe, wherein the wall of the cylinder has cut into it at least one tunnel, a flange, each tunnel having openings that emerge on either side of the flange that has a bearing face bearing against the joist and a free face, and for each tunnel, a holding system having a link, a shoe and a locking system, the link being housed in the tunnel with the shoe blocked in a first opening on the side of the free face and wherein the link exits via a second opening on the side of the bearing face and wherein the locking system attaches.

Abstract: A tool for laying a sealing strip around a protruding part of a connecting element protruding from a bearing surface, the laying tool including an annular duct having an outer surface configured to delimit, with the bearing surface and the protruding part, a cavity when the annular duct is positioned around the protruding part and in contact with the bearing surface, the annular duct including at least one orifice for supplying pasty composition and outlet orifices for injecting the pasty composition into the cavity to form the sealing strip. A method for laying a sealing strip using the tool is disclosed and an aircraft with at least one sealing strip obtained using the method.

Abstract: A boom for an electrical harness, including a straight bar extending in a longitudinal direction, and several supports distributed along and attached to the bar, to which supports at least one electrical harness is connected in operation. The bar includes at least two parts configured to slide relative to one another in the longitudinal direction so that a length of the bar can be adjusted.

The seal is able to divert the fluid and keep the space under the skirt fluid tight.

Abstract: The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the no-load voltage of the photovoltaic generator, determining a numerical value on the basis of the no load voltage, corresponding to the no-load voltage reading, and comparing the predetermined numerical value with at least one reference threshold value. When the predetermined numerical value corresponds to a value range limited by at least one such reference threshold value the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.

Abstract: The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the short circuit current of the isolated photovoltaic generator, determining a numerical value based on the short circuit current, said numerical value corresponding to the reading of the short circuit current, and comparing the numerical value determined with at least one reference threshold value. When the numerical value determined corresponds to a value range limited by at least one such reference threshold value, the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.
