Abstract: An installation for the batchwise destruction of noxious materials is described. The noxious material is fed batchwise into a combustion furnace holding a burning coal bed which induces combustion or detonation and also serves as damper for explosion fragments. Burning combustion gases are withdrawn from the upper part of the furnace and conducted while burning to a gas/solid separator. Optionally the burnt out combustion gases are bubbled through water or aqueous solution for the absorption of poisonous gas components and an essentially clean carbon dioxide/air mixture is discharged to the atmosphere.

Abstract: An installation for the destruction of solid fuel rocket engines. The installation comprises a pressure and temperature resistant vessel having a neck portion and a gas chamber portion with heat dissipating means. In operation the rocket engine is gripped in the neck portion and upon ignition of the solid fuel combustion gases are discharged into the gas chamber. Means are provided for the controlled discharge of combustion gases into a gas disposal device.

Abstract: A two-stage, shaped charge projectile having a rear principal charge and a front secondary smaller charge with an initiator-fuse assembly for sequentially igniting the secondary and principal charges so that the secondary charge is first ignited, followed by ignition of the principal charge after a predetermined time delay. The secondary charge is maintained at a set distance in front of the principal charge which is shielded from rearwardly expanding combustion gases and rearwardly flying debris when the secondary charge is ignited, with these gases and debris being diverted away from the principal charge after the secondary charge has been detonated.

Abstract: A shaped charge bomb whose liner is partially coated with a metal whose dity is greater than that of the liner which coating extends from an inner end on a circumferential line of the liner that results from the intersection of the inner side of the liner with a notional cylinder coaxial with the liner and having a radius not exceeding R/4 where R is the inner radius of the liner, the thickness of the heavy metal coating at each point meeting the equation ##EQU1## where T.sub.c is the coating thickness at a given circumferential line x, T.sub.1 is the liner thickness, .rho..sub.c is the coating density, .rho..sub.1 is the liner density and .beta. is the collapse angle at the circumferential line x.
