  • Patent number: 6629486
    Abstract: The technical field of the invention is that of devices for connecting and separating objects such as microsatellites with respect to a structure. More specifically, the invention relates to a separation device (1) intended to release a screw (8) which holds two subassemblies of a structure together, this release taking place through the movement of a release ring (5) by virtue of the gases produced by a gas generator (3). The main feature of the separation device (1) according to the invention is that a damping device, achieved by pressurizing a space (19) with the gases emitted by the generator (3), is created in order to decelerate then halt the release ring (5) before it can produce a mechanical shock at the end of its travel.

  • Patent number: 6344788
    Abstract: The present invention relates to electrical contactors used in electric motors comprising batteries. The present invention relates more specifically to an electrical contactor (1) for a battery, consisting of a hollow body (2) defining an upstream part (11) in which a pyrotechnic initiation device (3) is located and a downstream part in which a piston (4) is housed. Since the downstream part has three conducting studs (5, 6, 7), the main characteristic of the contactor (1) according to the invention is that it makes it possible, when the piston (4) moves due to the effect of the combustion gases, to pass instantaneously from a position corresponding to the electrical connection of the first two studs (5, 6) to a position corresponding to the electrical connection of the second stud (6) to the third stud (7).
