  • Patent number: 4860657
    Abstract: A projectile is described which consists of a contact head and a screen material canister which may be made of aluminium, attached thereto by bolts and, optionally closed with a cover. Contact rings are arranged on an outer casing of the contact head and are connected via firing leads to a primer capsule which is located in the contact head in a centrally disposed box-shaped charge chamber having a substantially gas-tight screw cover at its base and substantially gas-tight ports for the firing leads, the ports being sealed with a sealing agent.

  • Patent number: 4855605
    Abstract: Solid protective elements such as cesium, thallium or luletium are dispersed in or layered on an object so that when a high energy laser beam strikes the object a highly ionized plasma is provided that absorbs or reflects the laser beam. Alternately, the object to be protected is surrounded with a gaseous protective element such as krypton or xenon.

  • Patent number: 4621579
    Abstract: Device for producing a series of consecutive decoy clouds, in particular infrared decoy clouds which move progressively away from the actual target, in which several projectiles (A, B, C, D, E, F, G) are arranged within a thin walled discharge tube (1), each projectile is practically of identical construction and has a separate ignition disintegrator unit (10) for disintegrating it and for igniting and scattering the combustible charge (18) to form a decoy cloud, a separate ejection chamber (27) provided with a propellant charge cartridge (28) is provided on each projectile, each propellant charge cartridge (28) can be ignited via a separate electrically actuated ignition lead (5) by means of a command controlled ignition distributor unit (69) and each projectile has a separate percussion fuse (47) for the ignition disintegrator unit (10) which can be actuated by releasing its safety device (360 mechanically, its safety device (36) only being released after ignition of the propellant charge cartridge (28) wit

  • Patent number: 4435233
    Abstract: This invention comprises a process for the preparation of a smoke composition based on hexachloroethane, zinc oxide, and metal powder, in which zinc oxide granules obtained by high compression and subsequent crushing are used as a mixture component and the intermittent burnoff of previous smoke compositions of this type is thus avoided; the invention also concerns a smoke generator filled with such a smoke composition.

  • Patent number: 4227460
    Abstract: The invention concerns a practice war head device for an artillery rocket, comprising a frusto-conical head element having a hollow nose section and a hollow skirt section, an impact detonator mounted in said nose section, a tubular jacket connected to the skirt section, a tubular dividing element concentric with the tubular jacket together defining an annular volume, a fog producing substance based on a carbon halogen or halogen carbohydrate substance and reactive metal or metal oxide powders in said annular volume, and an ignition core of a quick-reacting ignition substance capable of high gas formation in the tubular dividing element, which is characterized in that the fog producing substance is loosely packed in the annular volume, that closure elements closing off said annular volume are provided at the nose side and base side of the annular packing, that at least the nose side closure element is displaceable towards the fog producing substance packing and that the connection between the skirt section of

  • Patent number: 4173931
    Abstract: An incendiary warhead comprises a destructible body carrying a plurality of stacked incendiaries. Each incendiary comprises a housing containing a compressed three-part icendiary filling. The filling comprises a flame substance for forming an intense flame, a thermit unit for forming a red-hot slag, and a combustion transfer substance which projects into both the flame substance and the thermit substance to be ignited by the former and ignite the latter. A tail unit is mounted at a top end of the housing to control the rate of descent of the incendiary. The tail comprises a hook, a pair of chains connected to the hook, and a vane connected to the free end of each chain. An anchor point extends from a bottom end of the housing and is in the shape of an arrowhead having barbed side edges.
