摘要： The invention relates to bearing means for a gun barrel (3) mounted in the breech casing of a weapon in which the breech casing comprises a sleeve member (2) enclosing a rear part of the gun barrel (3). The bearing means comprises a cylindrical sleeve (10) positioned between said breech casing sleeve member (2) and the adjoining external gun barrel surface. The sleeve (10) is provided with a spring part which consists of a plurality of finger springs (17) distributed about the peripheral surface of the gun barrel and engaging by the force of spring an enlarged cylindrical part (7) of the external gun barrel surface. This enlarged, cylindrical part (7) has such a length (d) in the longitudinal direction of the gun barrel that the finger springs (17) are engaged to said part (7) during the first phase of the recoil during which the shell, projectile or the like has not yet left the bore of the barrel (3). By means of this invention any play in the bearing means can be compensated so that the spread of shots is reduced.

摘要： The present invention relates to means for reducing the gun firing dispersion in a weapon system. The gun (4) comprises a gun servo for aiming the gun at a target. A programmable signal generator (5) is arranged to produce a damping signal (z) which is supplied to the gun servo system at the firing of the gun and which signal has such a character that the oscillating movements which are generated at the firing of the gun are counteracted. A recoil sensor (6) is provided for sensing the start of the recoil movements of the gun and emitting a trigging pulse to the signal generator (5) which in turn is producing said damping signal (z) preferably in the form of a pulse train in which the number of pulses, the pulse widths, polarities and amplitudes of individual pulses can be varied and which has a certain time relationship with the gun firing moment.

摘要： The present invention is directed to an assembly for stabilizing a vehicle supported on at least three pairs of wheels or tracks, wherein various pairs of wheels are selectively connected to one another in bogie style so as to reduce tipping movement of the vehicle chassis as the wheels travel over uneven terrain. A second embodiment of the invention discloses means to control the bogies with respect to their direction of rotative movement. Fluid damping means are provided for some or all of the wheels. These damping means are interconnected with longitudinal and diagonal conduits, with pumps and valves placed to control the movement of the fluid medium between the respective damping means.

摘要： An assembly for loading a projectile and a propellant charge into a barrel chamber of a firearm, wherein the projectile is movable from a first position at the side of a plane extending along an axis of the barrel to a second position coinciding with the barrel axis, and a rammer head assembly which pivots the propellant charge into line behind the projectile and drives the projectile and propellant charge into the firearm.

摘要： The invention relates to a device for increasing the tracking accuracy of an aiming system for a gun or the like which includes a gun servo. The gun servo comprises a special stabilizing and accuracy-increasing network (20) which comprises one or a plurality of integrating second-degree filters (25) the transmission functions (GR) of which have such a form that the amplitude as a function of the frequency has a maximum near the expected frequency of the base movements of the gun and/or the movement of the target, which makes it possible to have a high system gain around and below said frequency.
