Definitions

  • the method is characterised by the steps of arranging 25 a plurality of focussing means between the explosive mass and the target, said focussing means being in spaced relationship with liquid medium therebetween, and arranged to successively focus energy generated by the detonated explosive mass towards the target.
  • the method is characterised by the steps of arranging a plurality of focussing means between the explosive mass and the target such that each -focussing means serves to focus energy generated by 35 the detonated explosive mass to the target along a direction individual to that focussing means.
  • the present invention also envisages apparatus for carrying out the method comprising an explosive mass, one or a plurality of compressible focussing means, and means for supporting said explosive mass and said
  • the explosive charge 12, supported by the limb 13b of element 13, is of elongate form with its longitudinal axis extending between the explosive mass 11 and the target T. As illustrated, the explosive charge 12 reduces in cross - 1 Q -
