  • Patent number: 6453788
    Abstract: To remove means of combat such as mines and unexploded ordnance increasing use is made of hollow charges. Inherent in these is the risk of triggering premature ignition since their liners contain metals. According to the invention a hollow charge (4) suitable for eliminating means of combat is configured largely free of metals and has a liner (3) made of an electrically non-conductive, amorphous material. The material of choice is glass, which when configured correspondingly in addition has a projectile-forming effect and thus raises penetration capability. Apart from lowering environmental pollution the use of metal-free devices also eliminates false alarm messages in metal detectors during mine clearance and therefore significantly improves the safety of mine clearance personnel. The support (16) carrying the hollow charge (4) is fitted with a ball joint (13, 14), resulting in high adaptability to the place of use and type of combat means (M) concerned.

  • Patent number: 5447104
    Abstract: A galvanically conductive explosive is formed by the admixture of a small proportion of precious metal-containing platelets to a binder.
