Abstract: The method serves for adjusting a positioning of a longitudinal axis of a weapon barrel. An adjusting angle of the weapon barrel is changeable by at least one adjusting element. The weapon barrel is arranged so as to be movable relative to a weapon support in the direction of the longitudinal axis. A positioning of the weapon barrel relative to the weapon support is determined by measurement technology. The measurement values obtained as a result are supplied to a control device. The control device acts on the adjusting element in accordance with a predetermined functional relationship between the obtained measurement values and an input value for the adjusting element. The device for firing shell s is constructed for use of the respective method.

Abstract: The invention relates to a method and to an arrangement for harmonic-wave suppression in AC voltage-operated PTC heaters, especially in frequency-stable and frequency-variable alternating-voltage networks in aerospace applications. The problem of harmonic-wave suppression for AC voltage-operated PTC heaters, in which the harmonic waves are suppressed by superimposing a correction current, which permits a simple and economical generation of the harmonic-wave suppression signal, is solved according to the invention by generating a correction current in a correction current circuit arranged parallel to the PTC heater using an ohmic resistor (4). The correction current is generated and additively superimposed exclusively for suppressing the third harmonic of the heating current of the PTC heater.
