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.

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.

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.
