555 timer prvides selsctavel delay tiem between sweeps of wiper blades driven by motor in negative-ground system. Article also gives circuit modification for positive-ground autos. Delay time can ve varied between 0 and 22s. Timer uses feedback signal from cam-operated switch of motor to synchronize delay time with position of wiper blades.-J.Okolwicz, Synchronous Timing Loop Controls Windshield Wiper Delay, Electronics, Nov. 24, 1977, P 115 and 177.
