| 20090205796 | APPARATUS AND METHOD FOR CORRECTING BASIS WEIGHT MEASUREMENTS USING SURFACE TOPOLOGY MEASUREMENT DATA - An apparatus and method for correcting an areal weight measurement of a stretchable web using surface topology measurement data is disclosed. Areal weight may comprise a basis weight or a water weight. The apparatus measures a surface of the stretchable web with a basis weight measuring device to obtain a rough basis weight measurement. The apparatus then measures the surface of the stretchable web with a surface topology measuring device to obtain surface topology measurement data. The apparatus comprises a controller that corrects the rough basis weight measurement of the stretchable web using surface topology measurement data. The corrected basis weight measurement may be used as a feedback value in a real time manufacturing process of the stretchable web. | 08-20-2009 |

| 20080293926 | Preparation of Biomolecules - The present invention relates to a method of separating a target from a liquid, which includes providing a polymer in an aqueous liquid, which polymer comprises at least one hydrophobic portion; contacting the polymer-containing liquid with the liquid comprising the target; applying a stimulus to the resulting mixture; and maintaining it until a reversible phase separation is obtained. One phase is polymer-rich and contains target(s) and another phase is polymer-poor. By either maintaining the stimulus, or applying a different stimulus and maintaining it, the polymer-rich phase is transformed into a substantially solid phase. | 11-27-2008 |
