Timing valve control system
First Claim
1. A control system including:
- electronic circuitry including first output terminal means and second output terminal means;
first manually settable switching means connected to said electronic circuitry for causing said circuitry to produce a first output pulse at said first output terminal means at spaced time intervals as established by the setting of said first manually settable switching means;
second manually settable switching means connected to said elctronic circuitry for causing said circuitry to produce a second output pulse at said second output terminal means a predetermined time after each of the first output pulses as established by the setting of said second manually settable switching means;
said electronic circuitry including a first frequency divider counter, means including first decoder circuit means coupled to the first frequency divider counter and to the first manually settable switching means for providing said first output pulses at said first output terminal means and for applying a reset pulse to said first frequency divider counter;
a second frequency divider counter;
enabling circuit means connecting said first output terminal means to said second frequency divider counter to enable said second frequency divider counter when said first output pulse is produced at said first output terminal means;
means including second decoder circuit means coupled to said second frequency divider counter and to said second manually settable switching means for producing said second output pulse at said second output terminal means and for applying a reset pulse to said second frequency divider counter; and
an oscillator coupled to the first and second frequency divider counters for establishing a time base for the output pulses produced at the first and second output terminal means.

Abstract
A solid state timing valve control system and unit is provided which may be battery operated, and which has particular although not exclusive utility for controlling a water lawn sprinkler system. The control unit of the invention may be coupled to a water control valve in the sprinkler system, and it acts automatically to turn the valve on at the start of each of a succession of preset watering cycles, and to turn the valve off after a preset watering time at the completion of each such cycle. The control unit includes a latching-type solenoid for controlling the water control valve. The unit also includes a solid state miniaturized electronic system for introducing a turn-on pulse to the solenoid at the start of each preset watering cycle, and for introducing a turn-off pulse to the solenoid at the completion of each cycle.
