    Abstract: A coater for applying a coating medium to a moving surface includes a mounting; a coater rod bed connected to the mounting; and a coater rod carried by the coater rod bed. The coater rod is configured for applying the coating medium to the moving surface, and includes a hollow rod with a longitudinal bore interconnecting opposite ends thereof. A pair of fluid couplings are respectively attached to each end of the coater rod. Each fluid coupling has an internal fluid passage which is disposed in fluid communication with the longitudinal bore of the coater rod, whereby a thermal transfer fluid may be transported through the longitudinal bore of the coater rod.

    Abstract: An engine control system and method maintains an optimum exhaust fuel to air ratio in an internal combustion engine. A secondary air injection (SAI) pressure is measured in an SAI system. The SAI pressure measurement is converted into an SAI flow value. A fuel compensation value is obtained based on the SAI flow value. Fuel delivery is compensated to the engine based on the fuel compensation value. In a second embodiment, the fuel compensation value is obtained based on the SAI pressure measurement. Fuel delivery is compensated to the engine based on the fuel compensation value. In a third embodiment, a primary flow value is calculated at an air intake of the engine. A fuel compensation value is calculated based on the SAI flow and primary flow values. Fuel delivery to the engine is compensated based on the fuel compensation value.

    Abstract: Part load operating point for a controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through load dependent valve controls and fueling strategies. Optimal fuel economy is achieved by employing negative valve overlap to trap and re-compress combusted gases below a predetermined engine load and employing exhaust gas re-breathing above the predetermined engine load. Split-injection fuel controls are implemented during low and intermediate part load operation whereas a single-injection fuel control is implemented during high part load operation. Split-injections are characterized by lean fuel/air ratios and single-injections are characterized by either lean or stoichiometric fuel/air ratios. Controlled autoignition is thereby enabled through an extended range of engine loads while maintaining acceptable combustion stability and emissions at optimal fuel economy.

    Abstract: A control system for measuring a gap in an apparatus for pressing a traveling paper web as the paper web travels through the gap accompanied by at least one belt or felt, the apparatus including a press apparatus and a support surface defining a gap therebetween. A frame is provided for moveably supporting the press apparatus. An actuator is operatively disposed between the frame and press apparatus for selectively moving the press apparatus toward and away from the support to control the gap size. A transducer is mounted in either the press apparatus or support for producing a signal indicative of the pressure on the paper web as the paper web, belt and felt pass through the gap beneath the transducer. A controller is operatively linked with the transducer for receiving the signal, determining the measure of the gap as a function of the pressure, and causing the actuator to selectively move the press apparatus to control the gap size.

    Abstract: Part load operating point for a controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through a valve control operative to establish low pressure conditions within the combustion chamber into which fuel and exhaust gases are introduced. Combustion chamber pressures during the intake cycle are controlled lower as engine load decreases. Combusted gases are recirculated into the combustion chamber through a variety of internal and external recirculation mechanizations. A split-injection fuel control is implemented during low part load operation whereas a single-injection fuel control is implemented during intermediate and high part load operation. Split-injections are characterized by lean fuel/air ratios and single-injections are characterized by either lean or stoichiometric fuel/air ratios. Controlled autoignition is thereby enabled through an extended range of engine loads while maintaining acceptable combustion stability and emissions.
