Title: Russell Alan Johnston: Innovator in Flow Control Technologies
Introduction
Russell Alan Johnston is a notable inventor based in Alvin, TX (US), recognized for his contributions to flow control technologies. He holds a total of 8 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest patents is a system and method for controlling flow in a wellbore. This technique enables precise control over flow in a wellbore through a sophisticated flow control system. The system integrates a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism features a closure member that can be selectively moved between unactuated and actuated positions, allowing for greater flow in the unactuated state. This mechanism actuates either prior to or simultaneously with the flow control device, effectively reducing flow and minimizing loading forces against the flow control mechanism upon closure. Another significant patent involves pressure relief actuated valves. This valve design operates from one position to another upon the relief of applied pressure. It includes a housing with a bore and a valve member that responds to specific pressure levels, actuating to different positions based on the pressure applied.
