Title: The Innovative Contributions of Robert F. Estes
Introduction
Robert F. Estes is a notable inventor based in Foxboro, MA (US), recognized for his significant contributions to the field of engineering. He holds a total of 3 patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on pressure relief systems and electro-pneumatic transducers, which have applications in various industrial processes.
Latest Patents
One of his latest patents is the "Non-flowing modulating pilot operated relief valve." This invention features a pilot-operated pressure relief valve system that operates with a modulating action. The pilot valve is designed to be of the non-flowing type and includes sleeve and control stem members that translate within a channel. The sleeve member has an exhaust valve that relieves dome pressure on the relief valve when lifted by the control stem. The control stem responds to system pressure changes and includes an inlet valve that isolates the dome from system pressure when it reaches a predetermined level.
Another significant patent is the "Transducer assembly providing position output proportional to electrical." This electro-pneumatic current-to-position transducer consists of an electric motor with a permanent magnet for a stator and a spring-restrained coil pivotally suspended about the magnet for a rotor. The input current to the coil induces mechanical rotation, which is proportional to the applied current. The flapper attached to the coil moves toward the nozzle of a pneumatic circuit, changing the back pressure and allowing for precise control of the process.
