Abstract: A method for decoupling a high-frequency error signal from a high-frequency electromagnetic field in a heavy electrical machine includes decoupling a high-frequency error signal with at least one temperature probe acting as an antenna and being associated with a stator carrying an electrical winding. In a heavy electrical machine having a stator carrying an electrical winding, an apparatus for decoupling a high-frequency error signal from a high-frequency electromagnetic field includes at least one temperature probe being disposed in the stator for generating a low-frequency temperature signal. The at least one temperature probe has connecting lines leading out of the stator. A diplexer decouples the error signal from the temperature signal. The diplexer has an input to which the connecting lines are connected, a first output at which the temperature signal is furnished, and a second output at which the error signal is furnished.

Abstract: A rammer for artillery shells with a carriage behind the gun's tube that supports a tray in alignment with the powder chamber, that has a mechanism at the rear to intercept the shell, that travels on slides along a track paralleling the axis R of the tube, that is coupled to a piston-and-cylinder drive mechanism to accelerate toward the tube, and that has a braking mechanism to brake it at a prescribed distance from the rear end of the tube. The braking mechanism has a shock absorber position in the longitudinal midplane of the carriage with a piston that moves against the force of a friction spring inside a cylinder and that has a piston rod projecting forward beyond the front of the carriage with a stop mounted on it, whereby the stop rests directly against the rear end of the tube when the carriage is in the forward and braked position.

Abstract: A method and device for detecting and localizing fault in electrical installations includes performing partial discharge measurements and high-frequency measurements at least at one location in the electrical installation and optionally in all phases, selectively comparing the measurement values with each other and with calibration signals, drawing conclusions from the measurements regarding the location and the type of the fault, selectively continuously and periodically performing the measurements at least at three measuring points while the installation is in operation, simulating the electrical installation in a computer as a high-frequency network, while simulating fault with the signals originating therefrom at the measuring points, comparing any measurement values which indicate fault with the simulated signal values for different fault types and fault locations, and determining the type and location of the fault from the simulated signal values which best agree with the measurement values and from the

Abstract: An ammunition bunker for the main battletank turrets which is arranged behind the tank turret and whose walls are designed by predetermined break lines such that, in the event of an explosion of ammunition in the bunker, its outside walls are hurled off the sides of the tank thereby protecting the crew of the tank.

Abstract: A method for determining overheating in liquid-cooled windings of electric machines includes acoustically monitoring cooling liquid with at least one sound pickup, and detecting noises generated by bubbles in the event of local overheating if the boiling point of the cooling liquid is exceeded.

Abstract: In the turrets of tanks and other battle systems the ammunition is supposed to be stored in the ammunition bunker of the turret itself, in ammunition-stowage systems. Since tank turrets taper upward as a rule whereas the space available for storing ammunition should be completely exploited, the ammunition-stowage system as a whole can not be installed in the turret from above. To allow the ammunition-stowage system to be installed in the turret, the system is divided into three or four storage racks that can be installed individually in the turret from above. The outer storage racks widen outward in conformity with the slope of the side walls of the turret and have inwardly vertical demarcations, with the intermediate storage rack or intermediate storage racks having vertical demarcations or walls.

Abstract: An ammunition bunker has a plurality of storage tubes arrayed in rows next to and above each other. A doorway at the rear ends of the tubes is provided through which shelves are inserted and removed from the tubes. The doorway extends over an area which is less than that of the array of tubes such that given tubes lie outside the area of the doorway. In order to access these tubes, the given tubes are mounted at the front ends thereof for pivoting movement at the rear ends of each towards the doorway. Storage tubes disposed adjacent the given tubes in the direction of pivot have cutout portions so as to enable the extraction openings of the pivoted given storage tubes to be in approximately the same position as in the extraction openings of the cutout storage tubes.

Abstract: A mechanism that automatically opens the breech block wedge on a semi-automatic weapon, especially a tank cannon with a training liner. Mounted on the breech of the weapon is an electromechanical drive mechanism that includes an electric motor with a drive shaft on which is mounted an energy-saving flywheel that can be connected through adjustable couplings and a reduction gear to an opener shaft on which is mounted an opener lever that shifts the breech block wedge into the open position when the shaft rotates. The flywheel is accelerated to a nominal speed when the couplings are disengaged. Electronic controls then engage the couplings for a predetermined amount of time and turn off the electric motor. Some of the energy of rotation of the flywheel is transferred to the opener lever. The couplings are then disengaged and the electric motor turned on again. The electronic controls are practically activated by the firing pulse and/or the actual firing procedure.

Abstract: A multiplanar conductor bar for electric machines comprising subconductors superimposed radially in a number n of circumferentially mutually adjacent planes, n being a whole, even number between six and ten, inclusive, and transposed by at least 360.degree.. A total of two groups of two adjacent subconductor planes, respectively, are formed at upper and lower sides of the multiplanar conductor bar by exclusively mutual crossover of the semiconductors of the two adjacent planes. A total of n/2-1 groups of four adjacent subconductor planes, respectively, are formed at the upper and lower sides of the multiplanar conductor bar by exclusively mutual crossover of the subconductors of the respective four adjacent subconductor planes and exclusively in a transition between the respective outer and the respective inner planes of the four planes. The respective groups of four adjacent planes are mutually offset at the lower side with respect to the upper side by two subconductor planes.

Abstract: A gun barrel mount for a battletank in which the gun barrel and its cradle roller may be horizontally inserted into a relatively small aperture in the armor of the battletank turret and maintained in that position with a few threaded fasteners, the entire assembly being easily removable for replacement and/or repair. Insertion of the gun assembly into the turret horizontally obviates the need to separate the turret armor vertically which weakens the armor.
