摘要： During the production of consumable liquids such as milk, soup, and juice, the liquid consumable may be transferred from one location to another location through a fluid conduit. For example, a consumable liquid may be transferred from a storage tank to another destination through piping. At the end of the process, the piping may be purged with a flushing fluid to push the liquid consumable remaining in the piping to the end destination, thus preventing the volume of liquid remaining in the piping from being wasted. To control the flushing processing, fluid flowing through the piping may be fluorometrically analyzed to determine a concentration of product in the fluid. The flushing liquid can then be controlled based on the determined concentration. For example, the supply of flushing liquid may be terminated when the concentration of product falls below a threshold, indicating the flushing liquid is diluting the liquid consumable.

摘要： Methods and apparatus for coordinating operation of valves are disclosed. In some examples, an apparatus includes a valve controller to receive a first signal from a first control system to change an operating state of a valve, the valve controller is to provide the first control system exclusive control of the valve. In some examples, the valve controller is to receive a second signal from a second control system requesting permission to operate the valve, and send a response to the second control system indicating the first control system has exclusive control of the valve and has changed an operating state of the valve.

摘要： When a numerical controller enters a DNC operation mode, a host apparatus transmits NC data to the numerical controller. When the received NC data includes a sub program call, a repeat instruction or a branch instruction, the numerical controller stores search information that is required for executing these instructions. When the numerical controller includes search information, the host apparatus transmits, to the numerical controller, NC data corresponding to the search information. The numerical controller analyzes the received NC data and executes operation.

摘要： A water irrigation system may include a computer system, a sensing unit, an irrigation controller, and/or a water delivery system. The sensing unit may include a solar panel. Electricity produced by the solar panel may be supplied to the sensing unit. The sensing unit may assess climatological conditions in or near a zone to be irrigated. The sensing unit may be elevated at least 2 meters above the computer system. The sensing unit may communicate wirelessly with the computer system to provide output that is a function of the assessed climatological conditions to the computer system. The computer system may control irrigation of a zone to be irrigated at least partially based on the output from the sensing unit. A method of controlling irrigation may include allowing the computer system to control irrigation of a zone to be irrigated at least partially based on the assessed climatological conditions.

摘要： A process control system for multiplex operation of several process control loops. The system includes process input and process output units, analog and computer operation units and operator's interface stations, the exchange of process information between these units and stations being carried out by a time-sharing technique. The system is provided with a first data trunk through which process information through the data trunk is carried out in synchronism with address signals supplied to the address trunk in accordance with a cyclic control routine. Also included is a second data trunk which makes it possible at one's option to modify the cyclic control routine to select a desired mode of operation, the analog and computer operation units and the interface stations signalling whether operation in the manual control, analog control, or control mode is possible. State signals are generated at the operator's interface stations to the respective units to control their signal transmitting or receiving state.

摘要： An electronic process controller is disclosed having automatically bumpless operation. Changes such as transfer between manual and automatic modes, switching between set point sources and adjustment of control parameter values are all accomplished bumplessly with the aid of a settle circuit which adjusts the automatic control signal for bumpless switching while the manual memory freezes the process control signal at its last value before the change was initiated.

摘要： The invention provides a means for balancing a complex steam electric generating plant automatic control system when in the manual tracking mode before transfer to automatic. The tracking system utilizes the normal automatic integral functions to set demands for generation, governor valve position, feedwater flow and heat input to the steam generator equal to actual conditions prior to transfer. Thus, after transfer the system is immediately ready to perform its normal control functions without having to reposition normal working integrals from generation, pressure or temperature errors to satisfy unbalances internally within the system which existed at time of transfer.
