Abstract: The cable (2), at one extremity of which the connector is fixed, is wound onto the largest portion of the periphery of the drum (6) and is fixed at its other extremity to an arm (12) pivoting around the spin axis (7) of the drum (6). The spring returning the drum (6) clockwise is stronger than the one returning the arm (12) in the same direction. The pivoting arm (12) is housed in a cell (11) of the drum (6) and bears an articulated angle lever (17) whose extremity (18) is engaged in a notch (22) of the drum (6). A continuous traction ensures the full withdrawing of the cable, the drum then being kept in the corresponding "reinforced" position by the ratchet (24). At the time of disconnection, a new slight traction applied to the cable provokes the automatic disengagement of the ratchet (24) and the effective lowering of the cable (2).

Abstract: The fixing device includes parallel slides 1a, 1b, 1c and 1d constituted by double folds of flexible thin curtains disposed opposite one another. Each slide is made up of two lips 2a, 3a, 2b, 3b, 2c and 3c which are able to receive cards 14a, 14b and 14c by sliding. Between the sldies 1a and 1b, the curtain has an arced shape and bears tie rods 6 so that any traction applied to these tie rods 6 flattens the arc-shaped section of the curtain 1, thus pushing back the lip 2a towards the lip 3a and the lip 2b towards the lip 3b. Thus, clamping of the cards 14a and 14b is respectively obtained in the slides 1a and 1b.The invention is applicable to the fixing of printed cards in housings, particularly on board space and aeronautical vehicles.

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.
