| 20120130526 | Air Wipe and Sheet Guide Temperature Control on Paper and Continuous Web Scanners - Paper and continuous web scanners operate at varying and high temperature conditions. Regulating the temperature within the measurement gap between dual scanner heads during measurement and calibration modes of operation by employing air wipe and sheet guide temperature control assures consistent and accuracy sensor measurements of sheet characteristics. Air wipes blow pre-heated air into the measurement and the sheet guides are heated. The air temperature fluctuations that otherwise caused significant adverse effects on the sensors that measure, for example, the basis weight, ash content, and thickness of the moving sheet, are eliminated. | 05-24-2012 |

| 20120060718 | Rocker Wheel System for Scanner Carriages - A sensor head-transporting roller carriage has four pairs of wheels acting around pivot points at the four corners of the carriage, which is advanced along tracks that are supported by vertical structures. The lateral wheel spacing is chosen in correlation with the track support interval distances such that the vertical travel of all the wheels together is averaged, to be zero. As a result, variations in displacement alignment of the sensor are minimized. In addition, the pivot mechanism results in a fifty percent reduction in the effect of random vertical deflections caused by track debris or wheel concentricity etc. versus standard non-pivoting wheel sets. The roller carriage moves the sensor head along the cross direction to monitoring physical characteristics of a web of material that is moving in the machine direction. | 03-15-2012 |

| 20110290438 | Closed-loop Monitoring and Identification of CD Alignment for Papermaking Processes - Alignment is a critical component for modeling a cross-directional (CD) papermaking process. It specifies the spatial relationship between individual CD actuators to paper quality measurements. Misalignment can occur unexpectedly due to sheet wander or CD shrinkage variation. In certain applications and circumstances, a misalignment of one third (⅓) actuator zone width can result in significant paper quality degradation. Detecting a misalignment and identifying CD alignment in closed loop are highly demanded in paper mills but these are nontrivial problems. A technique for maintaining proper CD alignment in sheetmaking systems entails monitoring the alignment online, triggering closed loop identification if misalignment is detected, and then deploying the new alignment. No personnel intervention is required. | 12-01-2011 |

| 20100159121 | Differential Coat Weight Measurement by Means of Nuclear or X-ray Gauges - An improved differential coat weight technique employs a novel algorithm for measuring the weight of a coating material that has been deposited onto a sheet of substrate. The invention employs dual x-ray or nuclear gauges such that, even though the downstream sensor is never exposed to uncoated sheet substrate, imparting the downstream sensor with the ability to predict results that it would have yielded when measuring the uncoated sheet substrate, leads to the development of a coat weight calibration protocol from which the basis weight of the coating can be ascertained directly from measurements from the upstream and downstream sensors. No subtraction of results is required. Moreover, the two sensors do not need to be re-calibrated whenever the relative proportions of the coating and base substrate change. The technique is particularly suited for applications where the coating material and substrate are made of substances that have very different atomic numbers. | 06-24-2010 |
| 20100078140 | Pressure Equalizing Baffle and Coanda Air Clamp - An air stabilization system employing two parallel, opposite-facing Coanda nozzles, with each nozzle exhausting gas at opposite directions, subjects a moving flexible web to opposing forces effective to create local tension within the web. Each nozzle includes an elongated slot that is perpendicular to the path of the moving web. The nozzles serve as separate points along the machine direction for controlling the height of the web. The operative surface with the nozzles can exhibit a flush surface. The nozzles can be formed on elevated structures on the operative surface. The operative surface can be covered with a transparent substrate to minimize shape distortions on the moving web and to prevent debris from collecting around the sensor. An internal baffle is employed to channel air flow within each nozzle. The baffle equalizes the gas pressure across the nozzle and directs air flow towards it. By modulating the velocities of gases exiting the nozzles, the shape of the web can be manipulated to present a planar contour. The air stabilization system can be incorporated into a caliper scanner. | 04-01-2010 |
