Title: The Innovations of Thomas D Kegelman
Introduction
Thomas D Kegelman is a notable inventor based in Palm Harbor, Florida. He holds a total of eight patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on enhancing electrostatic imaging and driving inductive elements.
Latest Patents
One of Kegelman's latest patents is a method and apparatus for enhancing electrostatic images. This invention addresses the issue of stray background toner in electrostatic printer images by first electrostatically neutralizing any background toner charge and then removing the neutralized toner. An AC corona wire positioned between a developer unit and a background toner scavenger is employed to neutralize unwanted background toner. Alternatively, a high current density AC discharge between two electrodes separated by a dielectric layer may be utilized as a bipolar ion source. The toner can be scavenged using either a vacuum suction manifold or a rotating brush.
Another significant patent is the driver circuit for inductive elements such as CRT deflection coils. This invention includes a resonant bus, a bus capacitor, and at least two inductive branches grouped in pairs and connected to the bus. Each inductive pair consists of serially-connected inductive elements and diode means, allowing current flow in one branch to flow from the resonant bus while the other branch allows current flow back to the resonant bus. This configuration produces a sine-squared current in each branch, inverted with respect to the other, and generates a sinusoidal current in the bus capacitor.
