  • Patent number: 11465744
    Abstract: Aeronautical conveying and release device comprising a frame, an actuator releasing a device, a first and second hook holding the device, first and second locking toggles having a locking and unlocking position, first and second cams in contact with the first or second toggle in a first direction, movement of the first or second cam in a second direction causing the toggle to leave the locking position and the unlocking of the hook, a third cam actuated from and returns to an idle position, a fourth cam driven by the third cam into unlocking, the third cam unlocking the first cam, a fifth cam coupled to the first cam, a safety member with lever with a first position which blocks the unlocked cams, the first cam and the second cam being blocked unlocked, blocking the locked toggles, a second position where the lever is blocked by the fourth and/or the fifth cam, and a third position where the lever frees the cams.

  • Patent number: 8619403
    Abstract: This device comprises an electromagnetic coil (3) in which there is able to slide a piston (6) which has at least a portion made of a material having paramagnetic susceptibility and which is placed in contact with the mechanical member when the drive device (1) is in the rest state. Electrical energy supply means are provided in order to store electrical energy and to abruptly release this energy into the coil and thus apply the high-energy magnetic movement pulse to the mechanical member. According to the invention, the piston (1) comprises a stack (9) of blocks (11, 12) which are made alternately from the material having paramagnetic susceptibility and an insulating material; and the electrical energy supply means are provided in order to allow the energy to be applied to the coil in the form of a series of electrical pulses which appear as the piston (6) moves.

  • Patent number: 5078371
    Abstract: This device comprises an arm (15) for supporting the load, such as a roller member of a vehicle, articulated about a bearing axle (2), together with a resilient leaf (1) forming a spiral about the axle (2) and a cushioning strip (12) of an elastomeric material interposed between two consecutive turns (1c, 1d, 1e) of the leaf (1); the inner end of the leaf (1) is rigidly fixed to the bearing axle (2) and its outer end (1b) is fixed to the arm (15), these resilient members (1, 12) preferably being accommodated within the arm (15) in a leaktight housing 15a). Cooling element (14, 26) including a liquid which fills the housing (15a) to ensure the cooling of the suspension. The latter is entirely independent and of minimum bulk, and can be used in any terrain by virtue of the cooling element.
