Title: Demetrios J Rigas: Innovator in Tire Imbalance Detection
Introduction
Demetrios J Rigas is a notable inventor based in Skokie, Illinois. He has made significant contributions to the field of tire technology, particularly in the area of imbalance detection. His innovative approach has led to the development of a unique apparatus that enhances the accuracy of tire balancing.
Latest Patents
Rigas holds a patent for an "Apparatus for determining imbalance of tires and the like." This invention provides a method and apparatus for single plane balance determination of cylindrical parts, specifically designed for unmounted tires. The apparatus supports the tire for rotation about a horizontal axis and drives it at a constant slow speed. It utilizes torque monitoring means to generate an output proportional to variations in torque during the testing process. The electrical signal conversion means determines the magnitude of imbalance by calculating the difference between maximum and minimum torque output values. This information is displayed visually, and a marking device indicates the position on the tire where maximum torque occurs, helping to locate the center of gravity.
