Abstract: The method of coating composite material parts with a refractory and/or metallic product includes the successive steps which consist of applying to the walls of the polymerization mold a layer of a binder which is volatile or decomposable during the polymerization heating, projecting onto said walls at least one layer of said coating products, positioning the fiber and resin fabric layers inside the mold, carrying out polymerization under pressure by heating, and then removing from the mold.

Abstract: A device is provided for carrying and releasing a load such as a missile, comprising front and rear rails for supporting respectively front and rear lugs of the load. The rails are joined together by rigid elements so as to form a mobile assembly which may move along longitudinal slides of the carrier member. This latter has fixed stops and retractable stops which cooperate with the load for preventing any translational movement thereof in the carrying position. The movement of the mobile assembly in its slides frees the load from the rails so that it may be released.

Abstract: A device for retaining or releasing a wire for arming projectile fuses is provided, including a hook which retains the ring of the arming wire when the electromagnet acts, against the return action of a spring, through the mobile armature connected to the lever oscillating about the shaft. A catch pivoting about said shaft may engage by its end, a bearing face of said hook so as to maintain this latter in a position retaining said ring. A finger is carried by said lever and abuts against said catch, in the direction which frees this latter from the bearing face of the hook, when the lever is returned by said spring in the case of inaction of the electromagnet. A spring maintains the catch in contact with said finger.

The device comprises a mechanism with three roller escapements, one for each hook and a third one for releasing a tripping spring, the rollers and the loaded articulations being mounted on ball or needle bearings and thus allowing heavy loads to be released by means of an electromagnet of small volume and low consumption.

Abstract: The invention provides a device for carrying under an aircraft and ejecting loads which are suspended from hooks which may be raised so as to be set under support arms hinged about longitudinal pins, lowering of the arms against a load which is hooked on allows automatic positioning of stops automatically limiting the raising of the arms under the action of springs to different levels depending on the diameter of the load hooked on. The stops may form part of stepped cams urged by springs into the position bringing the lowest possible stop into action.

Abstract: A device for rapidly positioning and removing a loader in and from a carrying device on an aircraft, comprising a lever in the form of a horse shoe or stirrup having a cross leg between two side legs which support the loader and which are pivotably mounted to the carrying device at their ends opposite the cross leg, whereas this latter carries a single screw for fixing to the carrying device, actuation of this lever being facilitated by previously automatically latching the loader to the bottom of the carrying device.

Abstract: This method is directed to provide an improved bond between the metal reinforcement and a composite material, notably at a node comprising the connection between walls and a flange of composite material. It comprises essentially the steps of incorporating a metal reinforcement in the form of an assembly of three elements, namely a first element in the form of a hollow cylinder having a relatively broad base and connected to the flange, a second element capping the first one and provided with fins extending along the walls to be connected to the flange, and a third intermediate element consisting of a washer interposed between the first and second elements so as to distribute the fin pressure over the base surface.

Abstract: A device is provided formed by a case which contains, on each side of a ball for retaining the coupling member of the belt, two spring-loaded sliding keys cooperating alternately with the ball so that the retreat of one against the action of its spring allows the automatic advance of the other one either for locking said ball in the coupling member of said belt during penetration of this member into the case, or for releasing said coupling member and automatically ejecting same, depending on the key which is moved back against the action of its spring.

Abstract: The safety lock comprises a control member which prevents an untimely actuation of the jettisoning device by inserting a locking member on the path of a movable release member of this device. Simultaneously the safety lock releases braking members in order to allow nuts to rotate for ensuring the raising of the hooks to which the load is suspended.

Abstract: A revolver-cylinder type jettison device for transporting and jettisoning buoys on and from aircraft which comprises a number of jettisoning tubes each adapted to be loaded either with a single long buoy or with a pair of short buoys, and to be brought selectively to the jettisoning position by rotating the revolver-cylinder so that the selected tube overlies a single and common ejection and guide barrel formed in the aircraft. Each tube comprises buoy wedging and retaining devices for the two loading modes, the wedging device being so arranged as to retract automatically during the jettisoning, the retaining device being actuated by a pair of release cylinders. The buoys are ejected under the control of a pair of ejection cylinders responsive to upper and lower arms, the lower arm being retractable.

Abstract: Device for carrying under aircraft multiple loads disposed at variable distances between centers, the modification of the distance between centers being obtained by rotating load supports about longitudinal axes by means of bearings provided in the frame structure of the carrier device. Each load support may be rigid with circular sets of teeth engaged by matching teeth formed on arms fulcrumed by means of eccentric pins on the frame structure and controlled for a same load support by cam device rigid with a common shaft.

Abstract: A device for suspending and wedging loads under aircraft ensures, through a central control, the wedging of a load carried under an aircraft at a level determined by a pair of suspension hooks subjected to balanced stresses. The central control is obtained by sleeves which slide vertically under the action of rotary shafts and bevel-tooth gears, the vertical translation of these sleeves ensuring the downward movement of parts of bearings engaging the load.

Abstract: This device with independent hooks and automatic locking mechanism for hooking loads suspended under aircraft comprises an effort scaling-down device associated with each hook, mechanisms for coupling the two scaling-down mechanisms with each other, and the detent-positioning of this coupling mechanism through the medium of a third common scaling-down device. Thus, the preliminary manual cocking, i.e. the detent-positioning of the coupling, provides at the same time the simultaneous resetting of the first pair of effort scaling-down mechanisms associated therewith, so that the suspension hooks are free with respect to the retaining mechanism and can pivot to their closed position independently of each other under the action of the load suspension rings when the load is fixed in position, the third scaling-down device further assisting in reducing the efforts exerted on the common retaining pawl, the raising of this common pawl being necessarily attended by the simultaneous opening of the hook.
