摘要:
A two-barrel revolver-type firearm comprising two fixed barrels to be fired alternately, which are equipped with igniting systems and drives of their own, independent of each other. A drum with an odd number of chambers alternately aligns a chamber with each barrel for alternate firing of cartridges through the two barrels.

An insert for a weapon barrel for facilitating the firing of a small caliber ammunition comprises a tubular member having a bore defining a distinct caliber with one end having an exterior surface ending in a raised shoulder forming an abutment for a compensating bushing positioned on the exterior surface and abutting the shoulder. A sleeve is positioned on the exterior surface alongside and abutting against the bushing. This end of the insert carries a first locking mechanism for locking the sleeve radially in the barrel. This includes a tapered spreader sleeve which engages with a tapered exterior surface of the sleeve positioned on the insert adjacent the compensating bushing. The spreader sleeve is urged into bearing engagement with the tapered surface of the other sleeve by means of a knot threaded over the insert and advanced toward the spreader sleeve. A safety key is insertable through an opening in the sleeve and it engages in a longitudinal slot formed on the insert. The opposite end of the insert includes a collet which bears against a raised annular portion of the insert which forms a stop. The collet carries a plurality of damping elements over which a thrust collar having a taper is positioned and the clamping elements are urged by one or more clamping screws to engage this end tightly against the conical portion of the cartridge chamber of the weapon barrel. A spreader sleeve at this end is advantageously threaded over a collar formation of the collet at its outer end, and the collet itself is advantageously threadably engaged on the insert.
摘要:
An arrangement for gastightly sealing the gap between the cartridge chamber and the bottom of an insert which is received in a gun barrel 1 to be able to fire cartridges of a smaller caliber. The gastightness is obtained substantially by providing that the neck of the subcaliber cartridge case inserted in the cartridge chamber protrudes into the bottom of the barrel insert and that the outer surface of the neck snugly fits the cylindrical surface of the insert.
摘要:
A feed device for supplying solid urea granules into an ammonia generator arranged within or outside of an exhaust line for production of ammonia makes possible NOx reduction with the catalytic purification of exhaust of an internal combustion engine, gas turbine, or a burner, whereby the solid urea granules are stored in a holding tank. No compressed air support for transporting and metering the urea granules is required and transporting and metering of the urea granules adapted to the ammonia specifications is possible. The feed device has a housing with an inlet for supplying the urea granules and internally, a motor-driven, rotating disk with at least one spiral-shaped acceleration channel, as well as an outlet leading outward, to which a tube leading to the ammonia generator is connected.

摘要:
A front insert barrel bearing is adjustable by means of an adjusting device having two eccentric bushing arranged one within the other, of a front insert barrel bearing, the bushings are rotatable relative to each other, to change the position in which they support the insert gun barrel whereby a desired aiming direction of the insert barrel is made possible and a common mean point of impact with the barrel of the combat tank is achieved.
摘要:
A weapons system (10) with at least one barrel (12) is provided, wherein the barrel is arranged on a weapon carrier (14) which is mounted by trunnions (16) between cradle supports (18), and its elevation is adjustable. A separate ammunition container (26, 28), which is connected to the corresponding barrel (12) by an ammunition feed canal (22, 24), is associated with the barrel (12). The ammunition feed canal (22, 24) has a rigid first canal partial section (36, 44) and a rigid second canal partial section (38, 46), which are connected to one another via arc-shaped connection end sections (40, 42; 48, 50). The connection end sections (40, 42; 48, 50) are provided at the corresponding trunnion (16) such that the connection between the barrel (12) and the associated ammunition container (26, 28), and consequently excellent ammunition feed, are guaranteed in any desired elevation position.
摘要:
An adaptation cartridge comprises a firing pin casing which is screwed into a cartridge chamber or cartridge chamber tube and is secured against rotation by a radially displaceable slide. The cartridge is used for training on a gun having a subcaliber barrel adapter.
摘要:
The invention provides an electrical igniter for an adaptive cartridge of a subcaliber barrel system by which the firing pin extension (12) is arranged axially movable by means of a guide (13) made of an electrically non-conductive material. A slide valve (22) grips a safety rod (17) in the guide (13). The safety rod (17) is situated adjacent the breech mechanism (6) only such that the firing pin (12) borders on the percussion cap (29) of the cartridge (11). By an open breech mechanism (6) the safety rod (17), under spring tension, is moved in the direction of the cartridge (11) together with the firing pin (12).

The invention relates to a sport and transport device comprising at least one top panel (2), at least two wheels, and at least one drive device (2.4, 3). The top panel (2) is connected to a frame (1) in such a way that it can pivot about at least one pivot axis and the frame is connected to the wheels. The device (2.4, 3) is actuated by the movement of the top panel (2) about the pivot axis in order to drive at least one of the wheels (6). The invention is characterized in that the actuating means (5.1, 11) are disposed on the top side of the top panel (2), enabling devices provided on the frame (1) or the wheels (6) to be actuated in each position of the top panel (2). The device also comprises a specially designed suspension system between the front axle (10) and the frame (1).
