Title: Innovations of Eugene R. Jornod

Introduction

Eugene R. Jornod is a notable inventor based in Caledonia, Illinois, who has made significant contributions to the field of electronic and hydraulic actuator technologies. With a total of six patents to his name, Jornod's work reflects a commitment to advancing control systems in heating, cooling, and hydraulic applications.

Latest Patents

Among his latest innovations is the "Non-bridge type electronic actuator control." This invention features a quick-calibrate control module designed for heating and cooling systems. It responds to setpoint signals from a control potentiometer, driving a remote actuator to corresponding positions. The control module includes a motor coupled to the actuator and a feedback potentiometer that generates a feedback signal related to the actuator's position. Operational amplifiers combine the setpoint and feedback signals to produce an error signal, which a comparator uses to minimize the error by adjusting the motor. Additionally, a reference supply connected to the control potentiometer allows for calibration of the actuator's closed position, while a stroke adjustment potentiometer scales the feedback signal for the desired open position.

Another significant patent is the "Floating fluid-operated actuator." This invention features a piston in a reciprocating hydraulic actuator that carries a pump driven by an electric motor. The pump supplies oil from a low-pressure chamber to a high-pressure chamber, advancing the piston. An exhaust valve in the piston is normally closed by magnetic force from an energized coil, allowing for pressurization of the high-pressure chamber. When a second coil is energized, the valve opens, permitting oil to exhaust and retract the piston. This actuator can be controlled by a floating single pole, double throw switch, and it automatically shifts to a fully retracted position if electrical power is lost.
