Title: Frederick W. Woodruff: Innovator in Electrical Engineering
Introduction
Frederick W. Woodruff is a notable inventor based in Indianapolis, IN (US). He has made significant contributions to the field of electrical engineering, holding a total of 3 patents. His work primarily focuses on enhancing electrical systems and ensuring safety in electrical connections.
Latest Patents
One of Woodruff's latest patents is the "Ground Assurance Circuit." This invention is a bi-directional system designed to ensure that a ground connection is made in a three-wire conductor system. It includes a circuit for generating direct current potential related to the potential difference between the line 'hot' conductor and ground. Additionally, it features a second circuit for generating a direct current potential related to the potential difference between the line 'hot' conductor and ground. The system incorporates a male plug for insertion into a female receptacle, with prongs that can couple to either the line 'hot' or line neutral conductors. Each circuit includes a Zener diode for sensing potential across the 'hot' and ground conductors, ensuring safety and reliability.
Another significant patent is the "Fold-Back Power Supply." This electrostatic charging potential generator is particularly useful for coating dispensers, especially hand-held ones. The generator features a 'fold-back' voltage-current characteristic, which ensures that the energy available at the dispenser is less than that necessary for spark ignition of solvents and atomized coating materials. This innovation enhances safety while maintaining efficiency in coating applications.
