Abstract: A barreled weapon including a forward barrel segment which is tiltable about a trunnion through the intermediary of an actuating arrangement, and additionally includes a rear barrel segment which is similarly pivotable about the trunnion whereby the barrel segments, when oriented in their coaxial position, are sealed through the utilization of a sealing ring at a joint or separating location without necessitating any axial displacement of one of the barrel segments. The weapon includes a casing which is conducted along a screwthread and wherein, in the coaxial position of the barrel segments, the actuating arrangement rotates the casing so as to cause the latter, in conjunction with the sealing ring which is arranged thereon, to axially slide over the separating location between the barrel segments.

Abstract: An automatic muzzle or front loader weapon which possesses a weapon barrel which is pivotable in the direction of elevation or firing, and including a front or leading barrel segment which is latchable with the weapon barrel so as to be in coaxial alignment therewith. The barrel segment is pivotable into a loading position relative to the weapon barrel and which aligns with a loading tray into which there is insertable a projectile which is received from a storage magazine, whereby the projectile is slidable into the front barrel segment from the loading tray, whereupon the front barrel segment will then pivot in such a manner so as to cause the projectile to slide into the weapon barrel.

Abstract: Arrangement for a mortar in an armored vehicle having a gun laying device. A ball bearing support is provided for the mortar in a traverse on the vehicle and allows for the axial displacement of the mortar to facilitate breech-loading of munitions having different sizes while protecting the interior of the vehicle.

Abstract: A system for sealing a wedge-type breech mechanism for a weapon firing caseless ammunition using a clamping stud in the external drive and enclosed in a recess provided in a wedge which axially presses a sealing ring against the sealing surface of a chamber wherein gear actuated clamping studs press a sealing ring against its sealing surface by a radially displaceable segment.

Abstract: A ring closure arrangement for the breechblocks of large-caliber barreled weapons; including a closure seal ring having an angled profile in a longitudinal axial section thereof, with the seal ring being prestressed at a closed breechblock position for sealing the end of the barrel against the breechblock. A recess is formed in the breechblock, the seal ring being axially displaceable within the recess; and actuating means being located in the breechblock for imparting axial movement to and pressing the seal ring against the end of the barrel.

Abstract: A weapon having a tiltable cartridge chamber with sealing rings at opposite ends of the cartridge chamber for sealing engagement with the weapon barrel and with a head. A clamping lever is tiltably mounted on the chamber and is connected to the sealing rings for movement of the sealing rings to and from sealing position. A compensating mechanism is interposed between the lever and the sealing rings so that when one sealing ring seats, movement of the lever can continue and advance the other ring into seated position.
