| abstract |
A non-electric detonator device having a tubular shell that is closed at its bottom end and containing n a base charge of a detonating explosive at the bottom of the shell, n a priming charge of a heat sensitive detonating explosive composition adjacent to the base charge, n a rupturable membrane that seals the top end of the shell and forms an open volume between the priming charge and the top end of the shell and n a holder for holding a low energy detonating cord (LEDC) in abutting relationship to the membrane: n whereby on detonation of the LEDC the membrane is ruptured and the priming charge is initiated which in turn initiates the detonating explosive. |
