Patents by Inventor Harry Richard Mieney

Harry Richard Mieney 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).

  • Solid oxide fuel cell process gas sampling for analysis
    Patent number: 6630264
    Abstract: A method for monitoring process gas of a solid oxide fuel cell system is disclosed. The method comprises directing a portion of process gas from a chamber of the solid oxide fuel cell system to a main plenum chamber. A portion of process gas is cooled to a measurable temperature and directed to a sensor for analyzing. A solid oxide fuel cell system is also disclosed.
    Type: Grant

  • Fuel injector and method
    Patent number: 6065684
    Abstract: A direct injection fuel injector and method of operation wherein high fuel pressure exerting an opening force on an injection valve is slightly overbalanced by a return spring tending to close the valve. A first solenoid acts to open the valve against the excess return spring force and a second solenoid acts to close the valve when the first solenoid is de-energized. Rapid valve closing is provided by energizing the second solenoid before de-energizing the first solenoid, the force of the second solenoid when the valve is open being insufficient to overcome the force of the first solenoid holding the valve open. Thus, the second solenoid magnetic force is fully developed and quickly closes the injection valve when the first solenoid is de-energized. Various additional features are disclosed.
