Title: **Charles A. Robinson: Innovator in Hydraulic Control Systems**
Introduction
Charles A. Robinson, an accomplished inventor based in Galion, Ohio, has a passion for innovation that has led him to hold three patents in the field of hydraulic control systems. His work, primarily focused on material handling machinery, illustrates his commitment to enhancing operational efficiency and safety within the industry.
Latest Patents
One of Robinson's notable patents is a **Method and apparatus for controlling a lifting magnet of a materials handling machine**. This apparatus offers a solution for eliminating arcing between contacts within the magnet controller while preventing large voltage spikes. The design ensures smooth operation by selectively exciting the shunt field windings of a direct current generator. The voltage output is stabilized through a hydraulic motor that drives the generator at a constant speed, while a current transducer enables precise control over the flow of current to the lifting magnet based on real-time data.
Another significant patent by Robinson is the **Method and apparatus for controlling the flow of hydraulic fluid**. This innovation involves a hydraulic circuit defined in a manifold made from suitable materials such as aluminum or steel. The circuit effectively regulates the hydraulic fluid flow to ensure that the hydraulic motor operates at a constant speed, independent of the hydraulic pump's performance. Key components include a pressure compensated flow control valve assembly that balances pressure differentials to maintain consistent motor speed, along with surge suppression techniques to protect against undesirable hydraulic surges.
Career Highlights
Robinson is currently associated with Caterpillar Inc., a leader in the manufacturing of heavy machinery. His contributions to Caterpillar exemplify his role in advancing technology within the industry, particularly in hydraulic systems that are crucial for material handling operations.
