Radiant energy signal transmitter

Claim 1

A radiant energy transmitter including a d.c. to d.c. converter for converting a low d.c. voltage to a higher d.c. voltage; a d.c. storage circuit for storing d.c. energy from said d.c. to d.c. converter; a triggered radiant energy signaling device connected to said d.c. storage circuit; a trigger pulse circuit connected to supply a trigger pulse to said triggered radiant energy signaling device to initiate operation of said triggered radiant energy signaling device and an operator adjustable timer circuit coupled to said trigger pulse circuit for supplying thereto a pulse timing signal having a repetition rate selected by an operator, each repetition causing said trigger pulse circuit to provide a said trigger pulse, wherein said operator adjustable timer circuit comprises a crystal controlled means for providing a base time signal having a predetermined repetition rate, decade counter means responsive to said base time signal for enabling a said pulse timing signal when a given number of repetitions of said base time signal are counted, and operator controlled contact means selectively connected to said decade counter means for establishing the said given number of base time signal repetitions required prior to enabling said pulse timing signal.
