An expansive smoke configuration can be produced manually or automatically by the rapid, repeated discharge of smoke-forming liquid jets. A suitable device consists essentially of one or several movable tubes, each equipped with a nozzle, in conjunction with cartridges occupying the entire tube volume and having a liquid chamber and a propellant charge chamber. In case of two-component smokes, cartridges filled respectively with the two components (N1, N2) are fired in alternation. The device lends itself very well to automatic operation.

Device for the rapid producion of large-area smoke screens

A seeker head and an associated electronic system are mounted to the front end of a warhead in order to guide the missile to the target and to initiate detonation at the right time. To prevent the seeker head and the electronic system from confusing an impeding the hollow-charge jet produced by the hollow charge, the components arranged in front of the warhead are accelerated away from the warhead by a pyrotechnical charge shortly before hitting the target so that the seeker head and electronic system separate from the warhead and the hollow-charge jet produced by the warhead can thus hit the target without obstacle.

Missile with remote-controlled warhead

A cap-shaped cover for hollow-charge mines is adapted to form a hollow cavity adjacent to a portion of the mine. The cover, in its initial position, is in a folded, collapsed, introverted or the like closed condition and in its operational position, the cover is extended by a compression spring to assume a shell-like, hemispherical, or open configuration that defines the cavity. The cover includes at least one ventilating device for venting of the closed cover, a flexible body portion and the compression spring. The spring is formed of at least two separate, identical parts. These parts are arranged in the cover in such a way that the compression spring is symmetrical in all vertical section planes. The lead angle of a central turn section of each individual part of the compression spring, in the operational position of the compression spring, is 15.degree.-45.degree., at least in the zone adjoining an outer turn section. Preferably, an inner turn section of the compression spring is held in a continuous groove of the covering member.
