| 20080315120 | Focusing and positioning device for a particle-optical raster microscope - The invention relates to a focusing and positioning ancillary device for a particle-optical scanning microscope, a particle-optical scanning microscope including a corresponding positioning aid, and a method for focusing and positioning an object in a particle-optical scanning microscope. The focusing and positioning ancillary device includes an illuminating device, a camera, a display and a control unit. The illuminating device produces a collimated or focused light beam at an angle to the particle-optical beam axis which intersects the particle-optical beam axis at a predetermined position. The camera is sensitive to the wavelength of the light beam and records an image of the object, which is positioned on the object table, at a second angle to the particle-optical beam axis. The control unit produces an image captured by the camera on the display together with a marking which indicates the position of the particle-optical beam axis in the image. | 12-25-2008 |
| 20100102223 | Method and device for examining a surface of an object - A method for treating a surface of an object and a device suitable in particular for performing this method provide for examining the surface of the object with the aid of a particle beam to counteract the charge buildup on the object. A gas is supplied to convey the charge away from the surface and/or to neutralize it. | 04-29-2010 |
| 20100200750 | Particle beam system - A particle beam system comprises a particle beam source | 08-12-2010 |
| 20110031215 | Particle beam systems and methods - An inspection method comprises

| 20110049361 | Particle beam apparatus having an aperture unit and method for setting a beam current in a particle beam apparatus - A particle beam apparatus includes a first aperture unit having an adjustable aperture opening. The particle beam apparatus may include a first condenser lens having a first pole shoe and a second pole shoe. Both the first pole shoe and the second pole shoe may be adjustable relative to a second aperture unit independently of each other. The second aperture unit may be designed as a pressure stage aperture separating a first area having a vacuum at a first pressure, and a second area having a vacuum at a second pressure. Additionally, a method for adjusting a beam current in a particle beam apparatus is provided. | 03-03-2011 |

| 20080262251 | Process For the Recovery of Sterols From Organic Material - A process for recovering sterols from organic material containing sterols and sterol derivatives. In a first step (a) the organic material is reacted with at least one of polyols, polyamines, alkanolamines or monohydric alcohols to increase the amount of free sterols in the organic material; (b) reacting residual reactants, and their esters or amides with epoxydated components; and (c) separating the free sterols from the mixture by short path distillation, thin film evaporation, or flash evaporation. The recovered sterols can be further purified by a crystallization step. | 10-23-2008 |
| 20090099146 | Compositions Containing Sterol-derived Esters - The invention relates to sterol fatty acid esters of average chained fatty acids, having a chain length of 8 and 10 carbon atoms in a fatty acid distribution C | 04-16-2009 |
| 20100055190 | Sterol-Containing Compositions - The invention relates to a powder formulation containing sterol in the form of a super-cooled melt from sterols and sterol esters, provided that the sterol ester content is at least 30 wt % in relation to the content of the powder. The introduced sterol ester is a fatty acid ester having a chain length of 2 to 24, preferably 8 to 12 carbon atoms. As the sterol preparations are wettable and melt easily without the use of complex equipment, they can easily be incorporated into food, and produce, in particular, good organoleptic and sensory properties, in particular, in drinks. | 03-04-2010 |
