In order to improve the inductive transmission of pulses from a transmitter coil to a receiver coil of a projectile fuze, an insert formed of a steel band is mounted between a coil and a coil core formed of aluminum. This insert shields the coil against eddy current fields.

Receiver coil for a programmable projectile fuze

A self-destruction-type nose impact fuze for spinning projectiles comprising an axially displaceable firing pin which can be brought to bear at an axially displaceable impact body against the force of a self-destruction spring through the agency of centrifugal bodies as long as the spin of the projectile is above a boundary value decisive for the self-destruction. The impact body is located internally of a hollow compartment of the fuze housing, this hollow compartment being closed at the front. Within the aforementioned hollow compartment there is clamped a bushing between two oppositely situated support surfaces of the fuze housing. The bushing is internally provided with a shoulder against which bears an end surface of the impact body for the positive transmission of the impact shocks or percussions from the fuze housing forming the fuze tip to the impact body. Between the fuze housing and the outer wall of the bushing there is provided a hollow space or compartment, and the bushing consists of a material possessing a greater strength than that of the fuze housing.
