Title: La Moyne Durham: Innovator in Hydraulic Control Systems
Introduction
La Moyne Durham is an accomplished inventor based in Bartlett, IL (US). He holds three patents, showcasing his expertise in hydraulic systems and control mechanisms. His innovative contributions have significantly advanced the field of hydraulic technology.
Latest Patents
One of La Moyne Durham's latest patents is a method and apparatus for controlling hydraulic systems. This control system features a multi-phase stepping motor with a driver that supplies and controls DC current through each of the motor windings. This design ensures that no current is induced into the control winding from adjacent windings. The stepping motor precisely controls the rotation of an eccentric cam that engages an actuating plunger, which in turn actuates a control valve of the hydraulic actuating system. The driver receives control signals from a computer programmed to calculate user input command signals indicative of the desired system condition. It generates control signals that quickly achieve a rough approximation of the desired system condition. Once this approximation is attained, the computer generates new control signals for the driver based on feedback signals and system component characteristics to precisely achieve the desired system condition.
