Abstract: A nonelectric detonator device is provided for initiation by a detonator cord, the nonelectric detonator device being securable to a cartridge explosive, an explosive primer charge or one or more outgoing detonator cords, for example, for initiation thereof by the nonelectric detonator device. The detonator device includes an alignment member for securing a detonator cord in initiating relationship thereto. A second alignment member is provided for aligning outgoing detonating cords for initiation by the nonelectric detonator device.

Abstract: A nonelectrically initiated delay booster assembly includes a booster shell containing an explosive material, a cap well extending through one end of the booster shell into the explosive material, a nonelectric delay cap in the well and a detonating cord tunnel surrounded by a shock absorbing material affixed to the side of the booster shell or enclosed inside the booster shell. A signal carrier extends from a point within the cap to a point adjacent a detonating cord extending through the detonating cord tunnel, and a sensor member is affixed to that end of the signal carrier that is external to the booster shell in such a manner that it is in initiating relationship with the detonating cord extending through the detonating cord tunnel. A plurality of these boosters can be affixed to a single detonating cord downline when conducting multi-deck blasting operations.
