The invention is concerned with an explosive device for seismological marine reconnaissance, the device comprising a tubular casing containing the explosive charge and a detonator in which the detonator is provided with a plastics closure plug the plug being extended so that it projects beyond the end of the detonator and engages in the bottom opening in the casing containing the charge so as to seal the same against the ingress of seawater. To increase the sealing action the bottom end of the casing may comprise a conical portion terminating in a cylindrical neck, the extended end of the aforesaid plug having a flange for co-operation with the said conical end of the casing.

Rigid and flexible container type portable devices incorporating an intrinsically nonexplosive solid constituent of an explosive composition. Sensitizing of the device at the site of use by adding thereto a complementary intrinsically nonexplosive liquid constituent of the explosive composition, for admixing with the solid constituent. Such devices including built-in electrical initiators or fuse wells. Such devices constructed for coupling with a similar container containing the liquid constituent in a frangible capsule, including means for cutting or fracturing the capsule when the containers are moved together, and means for preventing fluid leakage from the assembly or the device. Such two container devices which are joinable in a first prearm, nonmixing position, and are movable into a second mixing position, in which the frangible capsule is fractured.

KNIGHT HERBERT G JR |
A packaged, and thickened, but generally pourable, inorganic oxidizer salt explosive of the aqueous slurry type is provided which contains a ''''release'''' agent to preclude adhesion of the mass of explosive to the inner wall of the container during gravitation of the mass therefrom. The agent is disposed so as to be in direct contact with said mass and the container inner wall across the mass-inner wall interface during the gravitation. In certain embodiments the agent serves as a fuel for the subsequent detonation.
