Abstract: The present invention provides an adaptive process control and profit depiction system which is responsive to both process measurement input signals, economic inputs, and physical environment inputs. The process control system features an interactive optimization modeling system for determining manipulated process variables (also known as setpoints). These manipulated process variables are used to position mechanisms which control attributes of a manufacturing system, such as a valve controlling the temperature of a coolant or a valve controlling the flow rate in a steam line.

Abstract: An adaptive process control system which is responsive to both process measurement input signals and economic environment inputs is provided. The process control system features an interactive optimization modeling system for periodically determining one or more manipulated process variables (also known as setpoints). These manipulated process variables are used to position directly controllable process parameters and attributes of a manufacturing system, such as a valve controlling the temperature of a coolant or a valve controlling the flow rate in a steam line.

Abstract: Disclosed is a differential temperature cell useful for measuring the difference in temperature between two environments. This dT cell comprises a first reservoir which is in fluid communication with a first chamber. Part of one wall of the first chamber defines a diaphragm, which also forms a part of the wall of a second chamber. The diaphragm provides a structure for measuring differences in pressure between the two chambers. The second chamber is also in fluid communication with a second reservoir.
