| 20110009664 | METHOD FOR PREPARING OPTIONALLY SUBSTITUTED P-HYDROXYMANDELIC COMPOUNDS AND DERIVATIVES THEREOF - The invention relates to a method for preparing optionally substituted P-hydroxymandelic compounds and derivatives thereof. The method for preparing the mandelic compounds of the invention comprises condensing in water, in the presence of an alkaline agent, an aromatic compound bearing at least one hydroxyl group and having a free para position, with glycoxylic acid, wherein said method is characterised in that said reaction is carried out in a piston-flow reactor. | 01-13-2011 |

| 20090306436 | PREPARATION OF PURIFIED HYDROQUINONE AND FORMING OF SAME - Purified hydroquinone is prepared and formed from raw compounds essentially containing hydroquinone associated with very small quantities of impurities including resorcinol and pyrogallol, and includes a distillation purification step in which the resorcinol and pyrogallol are eliminated, directly followed by a step in which the purified hydroquinone is formed. | 12-10-2009 |
| 20100059359 | SEPARATION AND PURIFICATION OF HYDROQUINONE FROM CRUDE MIXTURES THEREOF - Separation and purification of hydroquinone from crude mixtures thereof essentially containing hydroquinone in combination with very small amounts of impurities including resorcinol and pyrogallol, include a topping distillation allowing the resorcinol to be removed as the distillation top product, and allowing a crude mixture essentially containing hydroquinone and the heavy impurities to be recovered at the column bottom, such mixture then being subjected to a bottoming distillation which allows the pyrogallol to be removed at the column bottom and allows hydroquinone in a purified form to be recovered at the column top. | 03-11-2010 |

| 20110260341 | Power switch component having improved temperature distribution - A power switch component having a semiconductor switch and a contacting applied to a contact zone of the semiconductor switch is introduced. The contact zone has a semiconductor layer and a metal plating applied to the semiconductor layer. The semiconductor layer has at least one conducting region and at least one non-conducting region situated directly under the metal plating. | 10-27-2011 |

| 20120133924 | Measurement of the Positions of Centres of Curvature of Optical Surfaces of a Multi-Lens Optical System - A method measures the positions of centres of curvature of optical surfaces of a multi-lens optical system. The spacings between the surfaces are measured along a reference axis using an interferometer. Subsequently the centres of curvature of the surfaces are measured using an optical angle-measuring device. In the course of the measurement of the position of the centre of curvature of a surface situated within the optical system, the measured positions of the centres of curvature of the surfaces situated between this surface and the angle-measuring device and the previously measured spacings between the surfaces are taken into consideration computationally. In this way, a particularly high accuracy of measurement is achieved, because desired spacings do not have to be fallen back upon. | 05-31-2012 |
| 20120133951 | Method and Apparatus for Measuring Spacings Between Optical Surfaces of an Optical System - A method for measuring spacings between optical surfaces of a multi-lens optical system includes detecting the centring state of the optical system by taking into consideration all optical surfaces of the optical system. Then the optical system is adjusted in such a way, taking the centring state into consideration, that the optical axis of the optical system is aligned as far as possible with a reference axis. In a next step the spacings between the optical surfaces are determined with the aid of a short-coherence interferometer. The measuring-light ray directed onto the optical system for this purpose runs likewise along the reference axis. | 05-31-2012 |

| 20110239879 | PRINTING PRESS, METHODS FOR USING THE PRINTING PRESS, AND METHODS FOR HANDLING A WEB GUIDED THROUGH A PRINTING PRESS - A printing press has at least one first printing tower with at least one first printing unit that has several offset printing couples which are usable to print on one or on both sides of a first web which runs through the first printing unit substantially from the bottom to the top. The web is printed in multiple colors in the first printing tower. A dryer is arranged downstream of the first printing unit and along the conveying path of the first web. A former structure, with at least one former through which the web runs, is located downstream of the dryer. At least one nipping roller is located downstream of the dryer and upstream of the former. A spreading device is provided between the dryer and the at least one nipping roller that is located upstream of the former and along the conveying path of the first web. | 10-06-2011 |
