Patent number: 7982688Abstract: The invention relates to a device for representing optical information by means of a virtual image (P), in particular in a motor vehicle. The optical information is in the form of light beams extending from an image generating device (1), over at least one optical element to a surface and the virtual image is visible in front of, behind or in said surface. The light beams produce a beam path. Said invention is characterised in that an optical element (4), which influences beams, is arranged in the beam path between the image generating device (1, 2, 3) and the surface (WS), and that the optical element (4), which influences the beams, is arranged in the position thereof such that it can be modified by means of an adjusting device (5).Type: GrantFiled: October 12, 2005Date of Patent: July 19, 2011Assignee: Simens AktiengesellschaftInventors: Britta Lind, Bernd Ludewig, Ralf Mayer

Patent number: 7723261Abstract: The present invention refers to a catalyst for the manufacture of methyl mercaptan from carbon oxides comprising Mo and K compounds and oxides or sulfides of metals chosen from the manganese group. The improvement of the present process consists of the fact that carbon dioxide can be converted with higher conversions and selectivities to methyl mercaptan as compared to state-of-the-art technologies, with only minor amounts of carbon monoxide being formed as side product. Simultaneously, carbon monoxide can be easily converted into carbon dioxide and hydrogen by reaction with water using established water-gas-shift-technologies thus increasing the overall selectivity to methyl mercaptan.Type: GrantFiled: April 14, 2008Date of Patent: May 25, 2010Assignee: Evonik Degussa GmbHInventors: Jan-Olaf Barth, Hubert Redlingshöfer, Christoph Weckbecker, Klaus Huthmacher, Horst-Werner Zanthoff, Ralf Mayer
