Abstract: A fire suppression nozzle can include a first fluid channel configured to be in fluid communication with a first fluid having a first flow velocity and a second fluid channel configured to be in fluid communication with a second fluid having a second flow velocity. A mixer can be disposed between the first fluid channel and the second fluid channel such that the mixer is configured to induce streamwise vorticity in at least the first fluid exiting first fluid channel to cause mixing of the first fluid and the second fluid to reduce a flow speed of a mixture of the first fluid and the second fluid.

Abstract: A distributed intelligence control system for controlling a cross direction profile characteristic of a traveling sheet, such as paper, during production, includes a scanner for measuring a property of the sheet at a plurality of cross direction locations and producing output signals indicative of the cross direction profile characteristic. A host controller system coupled to receive the output signals from the scanner produces signals representing desired profile information, based on the output signals from the scanner. The system further includes a plurality of actuators, each actuator being operatively associated with a corresponding intelligent actuator controller.
