  • Patent number: 5499582
    Abstract: A projectile is described which consists of a contact head and a screen material canister which may be made of aluminum, 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: 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: 4370929
    Abstract: A contact head for a projectile which is capable of being fired from an electrically actuable launcher comprises a solid metal core formed on one side with a recess for constituting a propellent charge chamber in which are located a propellent charge and a primer capsule. The recess is closed by a base plate having breakage points for the egress of gases generated by ignition of the charge. The part of the core surrounding the recess is formed with first and second sets of bores spaced equiangularly about the axis of the core for receiving connecting screws for connecting the, contact head to a projectile and for receiving fixing screws for fixing the base plate to the core, respectively. An elastic protective member coaxially surrounds the head and is preferably subdivided into three rings, e.g. of rubber, which carry two metallic contact rings connected to the primer capsule by firing circuit wires.

  • 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: 4186664
    Abstract: This invention relates to a shell filling comprising smoke pots which are stacked one above the other in the firing direction in the shell casing and which consist of a closed metal housing and, accommodated therein, a smoke charge based on hexachloroethane, zinc oxide and metal powder, and to a process for producing smoke pots for shell fillings of this type.

  • Patent number: 4015355
    Abstract: An incendiary projectile carries an incendiary charge and a control charge arrangement for igniting and disintegrating the incendiary charge. The control charge arrangement is ignited by the propellant charge which launches the projectile and then immediately ignites the incendiary charge and finally causes disintegration of the projectile. In one embodiment the control charge comprises a first charge, including a glow and delay composition, and a disintegrating charge which is ignited by the first charge. In another embodiment the control charge comprises a glow and delay composition which ignites and then heats the incendiary charge to produce disintegration of the projectile. A novel tubular housing for the control charge is provided to prevent premature disintegration and minimize atomation of the incendiary charge.
