Patents by Inventor Giovanni Paolo Guaglione

Giovanni Paolo Guaglione has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Two-pressure gas circuit breaker with low pressure gas heating
    Patent number: 3983346
    Abstract: The gas-filled bushing of a two-pressure circuit breaker has a hollow central conductive stud. Heated gas is injected into the annular chamber between the stud and the porcelain jacket of the insulator at the insulator flange, and the chamber is isolated from the interior of the circuit breaker housing. This gas flows up to the top of the bushing and into the open center of the conductive stud, and down into the low-pressure housing of the circuit breaker. A gas orifice restricts the flow of gas into the bushing to a small value and a compressor maintains a given pressure differential between the low-pressure gas and its high-pressure source. The heated gas maintains the gas in the bushing and in the housing at a temperature greater than -40.degree.F.
