Abstract: The invention relates to a method for thermally initiated triggering of an aerosol fire extinguisher having a strike pin (6) acted upon by an inner spring (7) and locked in the stand-by state, and after thermal initiation, the lock is removed and the strike pin (6), driven by the force of the inner spring (7), strikes against a mechanical firing cap (1), whereby an initial firing material is released in the firing cap (1), igniting a booster charge (2), the hot conversion gas thereof igniting a pyrotechnic extinguisher charge in the aerosol fire extinguisher. In order that an absolutely reliable initiation takes place under the same conditions throughout the entire service life of the aerosol fire extinguisher, it is proposed that only immediately after the thermal initiation, when the firing pin (6) is still locked, the inner spring (7) is brought to the necessary tension for triggering the firing cap (1), and only after reaching said tension is the lock of the firing pin (6) automatically released.

Abstract: A fragmentation projectile having at least two adjacent casings including an inner casing having an inner surface and an outer surface, and at least one outer casing substantially surrounding the outer surface of the inner casing. An explosive charge is disposed within the inner casing, and an incendiary mass is disposed on the inner surface of the inner casing and facing the explosive. Structured zones are defined on the inner casing and include regions of lesser wall thickness than the portions of the inner casing surrounding the regions to cause a shock wave generated when the explosive charge is detonated to be transferred locally into the at least one outer casing to produce fragments of a predetermined size and shape.

Abstract: A method of producing a low-carbon iron material to cover an explosive charge and the iron material produced by same wherein the molten raw iron material is refined to produce a dissolved carbon content in the iron material of less than 0.01 wieght percent, the refined iron material is cast in a deoxidized state, and a homogeneous structure of the material is set by high temperature reshaping of the casting at a temperature greater than 880.degree. C. to produce a material grain size of less than 100 .mu.m.
