Title: The Innovative Contributions of Frederick O. Johnson in Monroeville, PA
Introduction
Frederick O. Johnson is a distinguished inventor based in Monroeville, Pennsylvania, with a remarkable portfolio of nine patents to his name. His innovative work has significantly impacted the fields of transportation and electrical engineering, reflecting his commitment to enhancing technology and safety.
Latest Patents
Among his latest inventions, Johnson has developed a unique **Conveyor Brake Control** system. This transportation apparatus features an advanced braking mechanism that improves the control of the speed of conveyor systems. By comparing the actual speed of the transportation device to a reference speed signal, the invention ensures that when the actual speed exceeds the reference, a brake is progressively applied. This is achieved through pulse duration modulation, allowing for a gradual and linear application of braking torque, which enhances both safety and performance. Additionally, this device can facilitate smooth acceleration, creating a more efficient transportation experience.
Another significant patent from Johnson is the **Method and Apparatus for Firing Angle Control of Series Connected Thyristors**. This invention addresses the critical issue of thyristor failure due to voltage imbalance during reverse voltage recovery. By introducing a mechanism that temporarily discontinues the continuous pulse based on a control signal, it effectively manages firing delay angles and reinstates the pulse in a double-pulse mode, thereby improving the reliability of electrical systems.
