Title: Harold V Clark: Innovator in Magnetic Tape Technology
Introduction
Harold V Clark is a notable inventor based in Los Altos, California. He has made significant contributions to the field of magnetic tape technology, holding a total of 3 patents. His work has had a lasting impact on the industry, particularly in the areas of automatic tracking and motor control systems.
Latest Patents
One of Harold V Clark's latest patents is an "Automatic tracking method for helical scan magnetic tape recorder." This invention addresses the challenge of maintaining correct reproduce head to track positioning in helical scan recorders. The technique involves reproducing recorded timing signals from adjacent slant tracks on magnetic tape and producing first and second simultaneous repetitive reference signals that are coherent with the reproduced timing signals. The system samples these reference signals and compares them to produce a tracking error signal if discrepancies arise.
Another significant patent is the "Dynamic control system for braking DC motors." This system controls a pulse-driven DC motor using a pulsed grounding switch and an inductor connected to the motor's armature. The control system includes a variable resistor that adjusts resistance based on the counter electromotive force (emf) generated by the motor. This innovative approach allows for efficient braking and control of the motor's operation.
