ABSTRACT:
Explosively activated delay device having a squib, a delay charge spaced therefrom, an output explosive charge, and thin metallic transfer disc between the delay charge and the output charge. The improvement in this invention is the provision of a dimpled transfer disc having an inwardly curved central portion in place of a flat transfer disc. A major advantage of the new construction is better heat transfer to the output charge, with consequent greater reliability in firing.
