Abstract: The invention relates to an armoured vehicle, especially a combat vehicle comprising a vehicle housing which is mounted on a running carriage and has a roof plate (1) on its upper side, in which an opening (1.1) is surrounded by a frame, the gun carriage of a weapon being mounted on a pivot bearing in said opening. Said frame consists of two parts which are fixed to each other and concentrically arranged inside each other, namely a non mechanically finished outer part (2), with wide tolerances, which is connected to the vehicle housing by means of welding, and a mechanically finished inner part (3), with narrow tolerances, which is positively engaged with the outer part. The pivot bearing of the gun carriage is arranged on said inner part. The production means can be sharply reduced by means of the inventive embodiment, as only the inner part (3) of the collar must be finished, as opposed to the entire vehicle housing.

Abstract: An armored vehicle, especially combat vehicle, having an outer wall (1) in which is disposed an air inlet opening (2) behind which a radiator is positioned in the interior of the vehicle. To produce a ballistic protective device at the air inlet opening, there is disposed in the interior of the vehicle, in the region between radiator and air inlet opening (2), a base plate (5), and the intermediate spaces between the outer edges of the base plate (5) and the inner edges of the air inlet opening (2) are closed off by cover plates (4.2, 4.3). The base plate (5) is provided in the central portion with an air passage below which the radiator is positioned. Above the base plate (5), essentially in the plane of the outer wall (1), a protective plate (7) is disposed and dimensioned such that an annular air passage slot is provided between its outer edges and the inner edges of the air inlet opening (2).

Abstract: An ammunition drum for a large caliber weapon may have two or more drum elements with parallel rotating axles. The ammunition is located in one or more concentric layers of ammunition holders around the rotating axles. To reduce the structural volume and to simplify the loading process, each of the drum elements may contain a recess extending at least (in the width of an ammunition) partially over the length of the drum element and from the circumference of the drum element at least partially to its rotating axle. The drum elements are located relative to each other in a manner such that in an alternating sequence in the position of one drum element in which its recess is located in the connecting plane between the rotating axles of the drum elements, the other drum element may be positioned with all of its ammunition holders in this connecting plane, from where the ammunition may be transferred in a translatory motion into the weapon.

Abstract: A cleaning device for guns in which a cleaning brush fastened to a brush carrier is moved to-and-fro in the barrel by means of a rod. A drive unit with drive wheels which can be engaged with the rod is arranged in the front of the muzzle of the gun so that the cleaning operation can be simply carried out with a small expenditure of time and labor.

Abstract: An apparatus for mounting relatively small and deformable elongated rails on a relatively large, generally horizontal, and nondeformable elongated rail beam has a stiff but limitedly elastically deformable elongated jig. A plurality of clamps spaced longitudinally along the jig are engageable with the rail for locking onto the rail at respective longitudinally spaced locations. Respective vertical and horizontal jacks transversely engage between the clamps and the jig for elastically deforming the jig into a desired shape relative to the rail beam. Holders and the like are provided on the jig for securing the deformable rails to the rail beam in predetermined positions relative to the deformed jig. If the rail section is to be curved in any direction the jig is appropriately deformed relative to the rail beam so its various holders and mounting fixtures lie on the appropriate curve. Such elastic deformation of the jig therefore perfectly positions these rail holders.
