Abstract: There are described a method and a device for suppressing an explosion-like fire, in particular of hydrocarbons, by means of a fire extinguishing agent, which under pressure at a speed adapted to the speed of propagation of the fire is distributed in the space directly surrounding the source of the fire. To ensure an efficient fire fighting without adversely influencing the environment, it is proposed to spray water as fire extinguishing agent by atomizing the same to form a water mist in a minimum amount of 0.03 l/m.sup.3 from a water reservoir (3) in the space directly surrounding the source of the fire.

Abstract: A breech closure for a barrel-type firearm is described, in which a flow passage for an igniting jet from an igniting cartridge held in a magazine extends through a breechblock. The breechblock is formed on that side which faces the magazine with a cylindrical recess, which is coaxial to the flow passage for the igniting jet and contains a metal sealing cup, the side wall of which contacts the peripheral surface of the recess and which has a bottom, which is formed with a central through opening for receiving the igniting jet and constitutes a conical disk spring, which bears on the contacting surface of the magazine around said through opening, the rim of which is enlarged to form a bead on the inside of the cup.

Abstract: An inertia projectile includes a penetrator (1) and a caliber-compensating propellent cage (2). The propellent cage has at its rear front front wall (9) perforations (3) opening into a cavity (4). The cavity is otherwise completely closed by a front wall (7) conically extending relative to the penetrator (1) and by a surrounding cylindrical mantle (6).

Abstract: In a gun which is provided with a recoil cylinder (8) against the recoil (11) and with a counter recoil cylinder (15) which cylinder (15) is filled with a hydraulic fluid, said recoil cylinder (8) and counter recoil cylinder (15) are mainted coaxially with the gun tube (1), wherein the counter recoil cylinder (15) encloses the gun tube (1) and the recoil cylinder (8) encloses the counter recoil cylinder (15). Therein the cylinder part (16) of the counter recoil cylinder (15) forms the piston part (7) of the recoil cylinder (8). The piston part (7) of the recoil cylinder (8) comprises a piston (10) which is guided within the cylinder part (9) of the recoil cylinder (8) leaving clear an annular gap (12), wherein the inner surface (13) of the cylinder part (9) of the recoil cylinder (8) is tapering towards the breech end.

Abstract: For a cannon movable by means of a traction vehicle (9) and comprising an upper mount (18) and a lower mount (1) comprising the running wheels (16) and being designed as a swivelling bolster, two spars (2,3) are hingedly connected to the lower mount (1) and are interconnected at their ends remote from the lower mount (1) by a supporting rod (4) for forming a four-bar mechanism. One of said both spars (2,3) carries at its end remote from the lower mount (1) a limber rod (6) having its free end located approximately in the vertical longitudinal center plane of the four-bar mechanism and carrying the trailer coupling. For steering the lower mount (1) carrying the running wheels (16), a control mechanism capable of being put in operating connection with the traction vehicle (9) is provided.
