  • Method for obtaining a linear detonating shaped cutting charge, charge obtained by said method
    Patent number: 9194667
    Abstract: The invention relates to a method for obtaining linear detonating shaped cutting charges (100) and to novel linear detonating shaped cutting charges (100) that are able to be obtained by means of said method. Characteristically, the sheath (101) of said charges (100) is shaped before filling and, once filled, it is only slightly deformed for perfect adaptation to the material contained therein. Ultimately, said sheath (101) has concave (C) outer walls (10a, 10b).
    Type: Grant

  • Resettable separation nut with a low level of induced shock
    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.
