TIME DELAY RELAY FOR USE WITH LOW ENERGY SHOCK TUBES IN DETONATION OF EXPLOSIVES

摘要

A detonating delay relay for shock or signal tube application so made as to be bidirectional. Comprising a delay detonator having a plug which holds two lengths of shock tube sealed at the ends. The detonation pulse is transmitted from one length of shock tube to the delay detonator. After a suitable delay, initiation of the other length of shock tube takes place.
