Abstract: A data carrier, such as a memory disk, is provided with a pyrotechnic layer which can be ignited to destroy the data on the carrier. The pyrotechnic layer has an inert lining and can be triggered by a conventional electrical ignitor. The layer is based on a thermite mixture having an excess reducing agent.

Abstract: A percussion primer compound for small arms, comprising a special metal such as zirconium as a reducing agent and a mixture of two oxygen carriers with oxidizing potentials of different magnitudes as oxidizing agent. The primer compound may be used in cartridge-type, small-caliber small arms such as is used for training purposes.

Abstract: A smoke-generating combustion charge is disclosed having a nitrate-containing oxidizing agent combined with wetted carbon granules to cause polar binding of the oxidizing agent. Such a charge produces a non-toxic smoke, and is environment-compatible, even when the charge fails to ignite, or is combusted incompletely. The method of preparation for the smoke charge comprises the separate treatment of the oxidizing agent and the reducing agent, followed by common mixing and press-forming to produce pellets.

Abstract: For generation of smoke screens for civilian and military applications, briquetted, combustible masses are used, which, by means of scattering charges, are spread in a buckshot-like manner. Smoke charges serve mostly toxic substances which, at least when failing to burn or when only partly burning, constitute an environmental hazard.According to the invention, there is provided a device consisting of nontoxic, hygroscopic smoke charges fully encapsulated in a moisture-impervious ignition layer. An ammunition body comprises smoke charges of differing sizes and geometries, and facilitates the ground-covering laying of smoke screens over large target areas.A preferred manufacturing method for the smoke charges and the ignition layer is described.
