ABSTRACT:
A system for registering and transmitting a preselected code to a receiving station which comprises a switch operable between open and closed states. An oscillator is responsive to the operation of the switch to the closed state for producing a pulse train. A control device is provided that has a plurality of states and is movable from state to state in response to an advance signal which is generated by an advance signal generator. The advance signal generator is operable by an energizing signal. A counter is connected to the oscillator for registering the number of pulses in response to one state of the control means. A transmitter is responsive to another state of the control means for connecting the oscillator to a transmission line. The counting means includes a generator for generating the energizing signal and for applying the same to the advance signal generator to change the state of control means when the number of pulses transmitted by the transmitting means is equal to the count registered in the counter.
