Title: Innovations by James F Deffenbaugh
Introduction
James F Deffenbaugh is an accomplished inventor based in Warren, Ohio. He holds two patents that showcase his expertise in the field of welding technology. His inventions are particularly significant in high-production environments, such as the manufacturing of vehicle rims.
Latest Patents
One of his latest patents is for a method and apparatus for detecting whether the gap in adjoining ends of a ring-like workpiece to be flash welded is of normal size. This invention provides a means to compare the movement of the movable platen of a flash welder with its position when the ends abut and flashing begins. If the ends are not materially beyond a predetermined normal gap, the welding action proceeds. However, if the ends are spaced beyond such normal gap, further action of the flash welding process is aborted, or a signal is activated. This invention is especially adapted for use in welding rings that are further processed to make rims for vehicles.
Another significant patent by Deffenbaugh is an energy monitor for flash welders. This invention monitors the energy used in flash welding operations by feeding two signals to the input of a multiplier. One signal is proportional to the welding current, while the other is proportional to the welder transformer secondary voltage applied to the work. The output of the multiplier is then processed through an integrating amplifier circuit and a level detector amplifier, allowing for effective monitoring of the welding process.
