Philip A Zanghi 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).

  • Automated yield monitoring and control
    Patent number: 8714177
    Abstract: A system is adapted to automatically maintain a desired yield level for a slurry flow. Measurements of the electrical conductivity of a slurry are taken and corrected for the effects of temperature and pressure. The corrected conductivity measurements are used to arrive at a value for system yield. The system automatically determines if the yield is too high or too low relative to a desired level, and controls the rate at which accelerator is added to the slurry in order to increase or decrease yield.
    Type: Grant
    Filed: March 23, 2012
    Date of Patent: May 6, 2014
    Assignee: W.R. Grace & Co. -Conn.
    Inventors: Dennis M. Hilton, Karl Taub, Keith Lipford, Philip A. Zanghi
