Latest Patents
Colwell's latest patents include a multivariable process control method and apparatus. This invention allows for on-line control of a process through feedforward computations of manipulated variable setpoints. These setpoints are modified during frequent optimization cycles by feedback trim, which is determined by the actual versus predicted effects of setpoint changes on the controlled variables. The system continuously polls and collects process, economic, contractual, and equipment parameter values to compute optimal setpoints. Additionally, drift factors are incorporated to provide on-line calibration of key measuring instruments. His second patent involves a modified polypropylene that includes a substantially isotactic homopolypropylene and a propylene/olefin random copolymer. This modified polypropylene features up to about 50 chain disruptors per 1000 propylene repeat units, enhancing its properties for various applications.
