Abstract: Circuitry for generating a virtually jitter free delay relative to a start pulse and for generating such delays over both integer and non-integer multiples of the time interval between timing pulses. The circuitry includes delay circuitry and signal generating circuitry. The delay circuitry is responsive to the start pulse and to the timing pulses for generating first and second signal edges. The second signal edge occurs later in time than the first signal edge, and both signal edges occur following the start pulse and in timed relation to the timing pulses. The signal generating circuitry is connected to the delay circuitry and has an output for generating an output signal which includes a timing cycle of known duration. The signal generating circuitry is responsive to the start pulse for initiating the timing cycle, the first signal edge for interrupting the timing cycle, and the second signal edge for reinitiating the timing cycle.

Abstract: This invention is directed to a method of fabricating kinetic-energy projiles from composite materials in such a manner that the type and degree of local inhomogeneity and anisotropy is controlled for tailoring the mechanical and physical properties of the projectile for different applications. A continuous rod of composite material is fed into a machine having a stationary holder or gripper and a rotatable holder or gripper which grips the rod. An induction heater heats a particular zone of the rod between the holders. Once the rod zone has been heated, the rotatable holder is rotated through a particular predetermined angular twist about the longitudinal axis, thereby applying a torque on the rod which causes the rod to deform in the heated zone. Depending upon the heated zone length, projectile noses in near-final shapes ranging from rather blunt hemispheres to sharp ogives can be formed.
