ABSTRACT:
A variable timing power storage arrangement for pre-setting a time interval between launch of a projectile and the initiation of a particular function or functions of said projectile and for storing power required inter alia for the initiation of said function or functions at the expiration of said interval, the arrangement comprising inductive coupling means for establishing before launch of the projectile an electrical coupling path between the projectile and control means associated with projectile launching means, signal generating means associated with the control means for generating a train of tone-burst modulated pulses for transmission over said inductive coupling means to the projectile, rectifying means in said projectile for rectifying the pulses of said train the first of which is utilized for charging up power storage capacitor means in the projectile to provide a d.c. power supply which serves inter alia for subsequently initiating a function or functions of the projectile and the subsequent pulses of said train being utilized for the setting of counter means in the projectile in accordance with the requisite duration of the time interval between launch of the projectile and initiation of the aforesaid particular function or functions and means in the projectile responsive to the firing or launch of said projectile to cause the counter means to commence a counting-out operation at a predetermined rate at the termination of which the power storage capacitor means is discharged for the initiation of said function or functions of the projectile.
