| 20100054650 | RADIAL ROLLER BEARING, IN PARTICULAR FOR STORING SHAFTS IN WIND TURBINE TRANSMISSIONS - A radial roller bearing for storing shafts in wind turbine transmissions, which has an external bearing ring with an inner runway, an internal bearing ring arranged coaxial thereto provided with an external runway, and a plurality of roller bodies that displace on the runways between the bearing rings held at regular intervals by a bearing cage. To prevent slip, the roller bodies are replaced by hollow rollers that have a greater diameter and a smaller elasticity module than the roller bodies ensuring, when the radial roller bearing is in the load-free state, permanent contact with the bearing rings, a permanent drive of the bearing cage and that the roller bodies have kinematic rotation. The hollow rollers have a higher bending strength, and their internal cover surface has a maximum surface roughness of Rz≦25 μm preventing localized peaks of tension, without any disaggregation in the axial direction. | 03-04-2010 |

| 20110028744 | PROCESS FOR MANUFACTURING LIQUID EPOXY RESINS - A process for the production of liquid epoxy resins, including: contacting a polyhydric phenol and an epihalohydrin in the presence of an ionic catalyst to form a halohydrin intermediate reaction product; concurrently: reacting a portion of the halohydrin intermediate reaction product with an alkali hydroxide to form a solid salt suspended in a liquid mixture including a dehydrohalogenated product and unreacted halohydrin intermediate, wherein the alkali hydroxide is used at less than a stoichiometric amount; and removing water and epihalohydrin as a vapor from the reacting mixture; separating the solid salt from the liquid mixture; reacting at least a portion of the unreacted halohydrin intermediate with an alkali hydroxide in the presence of water to form an organic mixture including an epoxy resin and unreacted epihalohydrin and an aqueous solution including a salt; separating the aqueous mixture from the organic mixture; and separating the unreacted epihalohydrin from the liquid epoxy resin. | 02-03-2011 |

| 20080201824 | Headwear piece with exposed surfaces having different appearances - A headwear piece with a crown having a wall for embracing a head of a wearer. The wall has an upper layer and an underlying layer. The upper layer has an exposed surface on the crown with a first appearance. The underlying layer has a second appearance that is different than the first appearance. The upper layer is configured to obscurely reveal the second appearance of the underlying layer to be seen in conjunction with the first appearance of the exposed surface on the upper layer. | 08-28-2008 |
