Title: John Sullivan: Innovator in RF Technology and Envelope Gumming Solutions
Introduction
John Sullivan is a notable inventor based in San Jose, CA. He has made significant contributions to the field of technology with a total of 6 patents to his name. His work primarily focuses on advancements in radio frequency heating and envelope gumming mechanisms.
Latest Patents
One of Sullivan's latest inventions is the Radio Frequency Dielectric Heater. This innovative device features a variable power output and stable output frequency. It includes a power controller that provides variable phase angle control of three-phase AC power. A delta-wye power transformer is coupled between the power controller and a rectifier circuit, which converts the stepped-up, high voltage AC power from the transformer into a DC power output. An RF oscillator circuit driven by the DC power output is coupled to a tank circuit. The load, comprising RF electrodes, creates an RF field to heat material passed through the field. Notably, the RF electrodes are coupled to the tank circuit in a manner characterized by the absence of any tuning components.
Another significant patent is the Envelope Gummer Cylinder Clutch and Brake. This apparatus is designed for applying gum to spaced portions of an envelope. It includes means for sensing the absence of an envelope on a conveyor belt feeding the envelopes to the gummer apparatus. In response to this absence, the gummer cylinder containing spaced gummer pads is precluded from rotating by disengagement of a clutch and simultaneous contact of a brake with the cylinder.
