Title: Innovations by Lary L Field
Introduction
Lary L Field is an accomplished inventor based in Caledonia, Illinois. He has made significant contributions to the field of electronic actuator control and hydraulic systems. With a total of 2 patents, his work showcases innovative solutions that enhance the functionality of heating and cooling systems.
Latest Patents
One of Lary's latest patents 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 to drive a remote actuator to corresponding positions. The control module includes a motor coupled to the actuator and a feedback potentiometer that produces a feedback signal related to the actuator's position. Operational amplifiers combine the setpoint and feedback signals to generate an error signal, which the comparator uses to minimize the error. Additionally, a reference supply connected to the control potentiometer allows for calibration of the actuator's closed position.
Another notable patent is the "Floating fluid-operated actuator." This invention involves a piston in a reciprocating hydraulic actuator that carries a pump driven by an electric motor. The pump supplies oil from the low-pressure chamber to the high-pressure chamber, advancing the piston. An exhaust valve in the piston is held closed by magnetic force, enabling pressurization of the high-pressure chamber. When a second coil is energized, the valve opens, allowing oil to exhaust and retract the piston. This actuator can be controlled by a floating single pole, double throw switch, ensuring that the piston remains in a commanded position even if electrical power is lost.
