ABSTRACT:
A transmitter coil is located at the muzzle of a firing weapon downstream of a muzzle velocity measuring device as viewed in the flight direction of a projectile after firing. The transmitter coil transmits a digital adjustment signal for inductively adjusting in the projectile during its passage through the transmitter coil, a counter for starting a delayed action fuze in the projectile. The individual digital adjustment signals are constituted by double pulses and a predetermined number such as at least 12 double pulses are transmitted by the transmitter coil to the receiver coil in the projectile. Electronic switches are utilized for controlling the operation of the transmitter coil. A filtering device is connected in circuit with the receiver coil and the counter in the projectile for eliminating interfering pulses which originate from the muzzle velocity measuring device.
