Abstract : An electromechanical coded actuator, upon receipt of the proper combination of electrical pulses, will unlock and cause angular displacement of an output shaft. The device comprises a rotatable notched flange integral with the output shaft, the former being keyed to the housing by a series of flat blades axially movable against a bias. A first solenoid sequentially positions a rotatable index arm over each blade, whereupon a second solenoid actuates the index arm to displace and lock selected blades in a manner to align a notch in each blade with the flange. the latter is then free to be rotated via a clutch-type coupling with the first solenoid. Additional actuation of the rotary solenoid releases the clutch allowing the flange and shaft to be returned to its original position by a spring bias, and also releases the original position by a spring bias, and also releases the displaced blades to lock the flange. An electrical switch actuated by the index arm defines the zero position. (Author)
