Abstract: A liquid propellant cannon includes an axially movable pump piston 25 which is exposed to propellant in a propellant chamber. The pump piston has a stroke that is shorter than the total length of the propellant chamber. For some or all of the rest of its length the propellant chamber 22 is divided by webs into parallel chamber portions. The pump piston causes uniform ignition of the liquid propellant charge during its relatively short stroke, while the chamber portions permit a substantially variation-free, compact reaction of the liquid propellant. The result is a relatively compact structure which provides uniform combustion behavior.

Abstract: A weapon arrangement for a gun barrel adapted to fire a projectile the propellant charge of which is loaded separately from the projectile in to the loading chamber of the gun barrel. Such projectiles have a long range and can be fired at a rapid firing sequence. The wedge breech block is slidably movable mounted in a mating slit of the bottom member at an angle of about 65.degree. with respect to the vertical plane. The mating slit is open towards the rear. A loading tray is pivotally mounted on an extension of the cradle which extends parallel to the gun barrel axis. The loading tray pivots laterally from an inoperative position to a loading position in which it is in alignment with the gun barrel axis so that a projectile from an ammunition magazine can be fed via two ammunition feed chains to the loading tray. A transfer arm is pivotally mounted about the trunion axis of the gun barrel and serves to transfer the projectile from the feed chains to the loading tray.

The mortar includes a dividable tube having a lower tube section and a mechanism for pivotally mounting the lower tube section for movement about an essentially horizontal axis to a loading position in which it is aligned with the opening in the side wall for breech loading of the mortar. A mounting device is connected with the vehicle for mounting the mortar for movement between a traveling position in which the mortar is positioned to travel with the vehicle and a firing position in which the mortar is positioned to fire a projectile. The traveling position is delimited by the region provided in the side wall for receiving the mortar and the firing position is located on the ground in the vicinity of the vehicle.

Abstract: A film leader card has a series of holes for receiving the projections on a succession of endless timing belts in a film processor to advance the card and an attached filmstrip through the processor. A middle-most hole in the series of holes is spaced relative to an adjacent hole in the series to match the pitch of the projections. Each of the holes in the series forward of the middle-most hole has a pitch slightly greater than the pitch of the projections. Each of the holes in the series rearward of the middle-most hole has a pitch slightly less than the pitch of the projections. Consequently, the leader card is projection-driven only at its middle-most hole since the projections received in the forward and rearward holes are substantially clear of any contact with the edges of those holes. This clearance between the forward and rearward holes and the projections facilitates transfer of the leader card from one timing belt to another timing belt in the film processor.

Abstract: A turret carrying an axis-defining gun barrel having a rear-end breech and pivotal in the turret about a horizontal elevation axis transverse to the barrel axis has an apparatus in the turret behind the breech for separately loading projectiles and charges into the breech. This loading apparatus comprises respective projectile and charge magazines in the turret behind the breech set up to feed the projectiles and charges to respective pickup locations both located in the turret horizontally to the same one side of the barrel axis. A loading arm pivotal about the horizontal axis is provided with respective projectile and charge grabs movable on and with the arm between respective pickup positions at the respective stations and loading positions aligned with the breech. Thus in the loading positions the projectiles and charges can be pushed from the grabs into the breech.
