Patents by Inventor Rhey Yang

Rhey Yang 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).

  • Patent number: 8402998
    Abstract: Systems and method for delivering materials to a tool are disclosed. A material delivery system utilizes two or more sources of the material to be delivered to the tool. One or more of the sources of the tool may be a batch mixer. The material delivery system also includes at least two material delivery recirculation lines providing material to at tool. The material delivery system may be manually or automatically controlled to switch supply of the material from one source to another, and/or to switch from one material delivery recirculation line to another.
    Type: Grant

  • Patent number: 8308845
    Abstract: Systems and methods for processing high purity materials are disclosed. A unit operation processes a material stream, an operational parameter of the unit operation is monitored, and a standby unit is charged with pressurized gas to achieve system pressure. The material stream is diverted to the standby unit in response to the operational parameter of the unit operation registering a threshold value. Flow exiting the standby unit is first vented via an outlet, and then directed toward a point of use after the pressurized gas has been purged. The unit operation may then be serviced and subsequently brought back online. A second unit operation may process a second material stream simultaneously, and the second material stream may be periodically diverted to the standby unit in like manner, thus reducing line pressure variation. The disclosed method may be performed manually or implemented automatically through use of a controller.
