Abstract: An ammunition positioner for upright ammunition shells has an arm mounted on a base, capable of being extended parallel to the plane that the shell stands on. The positioner has a pincher-like pickup with two jaws that pivots parallel to that plane. The pickup and its jaws are both controlled by a motor that is secured to the base. The motor's output wheel is coupled to the intake wheel of a transmission by way of a rotating splined shaft and a hollow shaft. The splined shaft is mounted in the base and parallel to the positioning arm. The hollow shaft is coaxial with the splined shaft and is mounted in and parallel to the positioning arm. A sleeve travels back and forth on the splined shaft and couples the hollow shaft to the splined shaft such that the former will rotate along with the latter. The transmission has two cogwheels, one of which is always coupled to the intake wheel and the other of which is coupled to and can be uncoupled from the intake wheel by a gear that can be disengaged.

Abstract: A swivel truck frame of high torsional flexibility for rail vehicles is provided comprising a pair of generally straight longitudinal beams running parallel to one another, said longitudinal beams connected to one another by parallel running crossbeams to define a rectangular frame, said crossbeams being welded to said longitudinal beams, said crossbeams being disposed under said longitudinal beams, the lower chords of said longitudinal beams being welded to the upper chords of said crossbeams, said longitudinal beams being further interconnected by at least one middle crossbeam disposed between said parallel running crossbeams.

Abstract: A control switch for the input of a signal into a fire direction computer to select the ammunition for weapons from which a plurality of types of ammunition can be selectively fired. The control switch includes a plurality of switches each corresponding to one type of ammunition. A plurality of flip-flops, each corresponding to one switch, each have a set input connected to the associated switch and is settable thereby and each has at least one reset input connected to the remaining switches and is resettable by any one thereof, whereby only one flip-flop is set at a given time corresponding to the selected ammunition resulting in the output thereof providing the only input signal to the fire direction computer.

Abstract: A mounting for an ammunition container for mounted rapid-fire weapons comprising a yoke disposed on a bracket which yoke is pivotable about a horizontal axis disposed at about the level of the upper edge of the ammunition container to be contained therein, the yoke being secured at its lowermost position by a catch means. Disclosed in the application is such a mounting in which means are provided to urge an ammunition container toward a rapid-fire weapon. Means are also provided to dispose the ammunition container precisely within the mounting, to rapidly remove any container top so as to permit the rapid feed of ammunition into the weapon. A device for insuring that the yoke bears against the ammunition is provided by which inadvertent release of the same is precluded.

Abstract: A system for the temporary sealing of the interior of an armored vehicle, especially tanks, against the penetration of liquid or gaseous substances is disclosed. The system is characterized by a tubular seal connected to a central operating system disposed in the interior of the armored vehicle. The vehicle is equipped with at least one ventilation aperture provided in an exterior wall of the armored vehicle which wall defines an interior of the same. The ventilation aperture comprises a ventilation valve in an aperture responsive to compressed air. The ventilation valve is connected to the central operating system and has provided thereover a protective device disposed on the exterior of the armored vehicle. Preferably, the tubular seal within a groove on the chassis or on the turret of a tank.

Abstract: A motorizable swivel truck for rail vehicles, especially streetcars, having a truck frame on which a cradle frame lying transversely of the direction of travel is supported by at least one coil spring, and the car body rests upon the cradle frame through a support means which permits wide swiveling of the swivel truck. The coil truck frame consists of two longitudinal members having a generally underslung configuration and whose middle portion has a level lower than the level of either end of each longitudinal member. The longitudinal members have end portions which have a closed profile while the middle portion has an open profile. The swivel truck frame comprises two cross members which are disposed between the wheel axles and may also have a cross-sectional open profile. The ends of the cross-sectional members are connected to the longitudinal members suitably by being welded to the same.

Abstract: A rail vehicle, especially a passenger train car for high-speed trains provided with air springs associated with each swivel truck in symmetry with the longitudinal central plane, their distance from center to center being so much smaller than the track gauge of the wheels that, if one air spring bellows fails, the weight of the car body will be distributed to the wheels in such a manner that the unloading of the wheels on the one side will not be such as to create the danger of derailment. To stabilize the car body the latter is joined to the swivel truck frame by a resilient linkage which permits vertical movements of the car body but opposes any lateral tilt of the car body by means of a resilient force. The resilient linkage is able to cause the car body to tilt towards the inside of curves when the car is negotiating curves. The swivel truck can be designed either as a driving or as a non-driving truck.
