  • Method for control of a chemical manufacturing process
    Patent number: 6590131
    Abstract: A method for monitoring and improving the performance of a chemical manufacturing process by monitoring transients associated with the operation of process equipment located dowstream of upstream equipment is disclosed. Transients on signals such as the motor current to downstream powder feeding equipment provide early indications of changes in chemical process performance which can then be corrected by altering chemical manufacturing process conditions.

  • Automated flow rate machine
    Patent number: 5016467
    Abstract: An apparatus and method capable of automated flow rate measurements of thermoplastic polymers which includes mechanisms for automatically loading a test polymer into a test cavity of a heating block and mechanisms for automatically cleaning the test cavity and a piston rod movable therein. The test cavity can be provided in the heating block or can be defined by a sleeve/die insert which also serves as a sample receiving cavity and which is movable into and out of a heating block for carrying out a rheological test of polymer material received in the sleeve/die insert.
