  • Patent number: 10288391
    Abstract: A shaped charge comprising a containment shell, an explosive charge placed in the containment shell and having a V-shaped surface, a fuse placed behind the explosive charge, and a layer of projection material placed in front of the V-shaped surface of the explosive charge. A layer of pyrogenic material is used for heating the projection coating. This pyrogenic material can also be mixed with the explosive charge.
    Type: Grant

  • Patent number: 10228224
    Abstract: A method and device enable the linear separation of two elements attached to each other through two connecting surfaces which are conical in this example, of a first element and a second element respectively, using thermite placed on the other side of the wall of the outer element, facing a connecting arrangement placed between both connecting surfaces. An electrical triggering of the thermite causes a quick and local warming-up, at the connecting arrangement which, after melting, enables both elements to be separated.

  • Patent number: 10184766
    Abstract: A method and device enable the linear separation of two elements attached to each other through two connecting plates of the first element and the second element respectively. An arrangement connecting and separating the two connecting plates are mixed and comprise a layer. The connecting arrangement comprises soldering, glue, or resin, whereas the separating arrangement comprises thermite. These elements can also be layered rather than mixed. An electrical triggering of this assembly causes its quick and local warming-up and thus enables both of these elements to be separated.

  • Patent number: 10072915
    Abstract: A method and device enable the linear separation of two elements attached to each other, through two respective connecting surfaces of these two elements. A connecting layer is placed between both connecting parts. Thermite is used to melt this connecting layer. The thermite can be placed on the other side of the first connecting part towards the first element, a heat protecting plate completing this assembly. The thermite can also be placed in grooves provided on the connecting surface of the second connecting plate to be directly in contact with the connecting layer.
