Abstract: A retrofit kit for a printing press adjustment hydraulic actuator. The hydraulic actuator is maintained to benefit from its mounting position and alignment, but the hydraulic fluid is removed. A hydraulic actuator shaft is attached to a mechanism that converts the rotary motion of an electric motor to linear motion. The electric motor provides faster and more accurate control of the hydraulic actuator shaft than the hydraulic fluid, providing for faster adjustment of the printing press.

Abstract: A controller for motor activation providing accurate and repeatable position changes by pressing and releasing a push button switch. Repeatable position changes are made in an advance direction by triggering a digital counter for a predetermined number of cycles of a reference clock signal. Backlash in retard motion of the motor is reduced by similarly asserting a retard motor input for an amount of time determined by another digital counter with a following advance correction made automatically after the retard signal is applied, by applying a predetermined retard-advance movement amount, as again counted by a digital counter. The advance binary amount, the retard binary amount and the retard-advance binary amount of set through binary switch inputs to respective counters to count the respective time periods (TG3, TG1, and TG2).

Abstract: A visual indication for a motor controlled shaft, especially useful for retrofitting hand controlled printing presses.
