  • Patent number: 6644167
    Abstract: The present invention relates to a method and an arrangement to mitigate damage to a rotary cultivator type mine clearer. In the event of detonations, triggered by the mine clearance tool, the present invention acts to mitigate damage to the mine-clearing tool, the mechanical mine clearer drive function, and its suspension. Detonation forces are, in a first stage, damped by hydraulic and/or mechanical damping members which are coupled between the bearing points of the tool and the engine driving the tool and which connect those parts to form a combined unit. If the detonation force is not absorbed, then, in a second stage, the detonation force remaining after the first stage damping, is counter to some of the combined weight of a unit formed by the tool, its bearings and the engine driving the tool.

  • Patent number: 6481328
    Abstract: A device for assembling complete propellant charges from a plurality of modular propellant charges. A plurality of magazine tubes each receives a plurality of modular charges. Each magazine tube has an outfeed aperture. A plurality of ejectors eject the modular charges from the magazine tubes. At least one retrieval tube receives the modular charges from the magazine tubes. A manipulator alters a position of the at least one retrieval tube adjacent any of the magazine tubes for retrieving the modular charges from among the magazine tubes. The manipulator also alters the position of the at least one retrieval tube to be adjacent a loading mechanism of an artillery gun.
