| 20080247515 | Rotor - The invention concerns a rotor combining the advantages of a single-piece wheel, which, when it is operating, only exhibits a slight and constant variation in shape (expansion shift) in the guiding region of its path, with those of a rimmed rotor with spokes, enabling, by virtue of its light weight, the bearings to be easily arranged. Further, because of its tendency to exhibit a tensile stress higher than a bending load, the rotor provides for a wide selection of rotor materials. The rotor has at least one segment arranged on the hub, enclosing at least a closed recess. A preferred embodiment concerns a rotor comprising at least three rotor segments uniformly distributed, said segments having each two recesses, such that the regions of materials surrounding them are in the form of three spokes arranged substantially parallel. The inventive rotor is particularly suitable for receiving graphite crystals, in the form or a vibrating disc for a back-scattering spectrometer. | 10-09-2008 |
| 20080273664 | X-Ray Device with Scattered-Beam Suppression - The invention relates to an X-ray device with an X-ray radiation source and with a preferably digital detector, which is placed in the beam path of the radiation source behind the object, particularly behind a patient. Scattered-rays are suppressed by means of a scanning device that scans the object and the detector only in sections. During a half-scanning process, the X-ray image is composed of half images, one image half being faded out. | 11-06-2008 |
| 20090103686 | X-Ray Imaging with Continuously Variable Zoom and Lateral Relative Displacement of the Source - An inspection system based on penetrating radiation in which the field of view of a scan may be varied. First and second primary limiting apertures are provided for interposition between a source of penetrating radiation and an inspected object. This allows for significantly increasing the flux of penetrating radiation on this narrowed region of interest, thereby advantageously improving detectability. The relative position of the source with respect to either the first or the second aperture may be varied, in a direction either along, or transverse to, a normal to the aperture. | 04-23-2009 |
| 20090141865 | SHIELDED SAMPLE CELL INSERTION AND REMOVAL APPARATUS FOR X-RAY ANALYZER - A shielded sample cell insertion and removal apparatus for an x-ray analysis instrument, including a sample cell setting to hold a sample cell, an outer surface of which exposes the sample to an x-ray engine; and a shielded area positioned over the sample cell, to shield an area beyond the sample cell from x-rays transmitted from the x-ray engine. Upon moving the apparatus into and out of the instrument, the sample cell is moved into and out of an analysis position, while retaining shielding of areas beyond the sample cell from x-rays transmitted from the x-ray engine of the instrument. | 06-04-2009 |
| 20110293072 | Beam Forming Apparatus - The present specification discloses a beam chopping apparatus, and more specifically, a helical shutter for an electron beam system that is employed in radiation-based scanning systems, and more specifically, a beam chopping apparatus that allows for variability in both velocity and beam spot size by modifying the physical characteristics or geometry of the beam chopper apparatus. The present specification also discloses a beam chopping apparatus which provides a vertically moving beam spot with substantially constant size and velocity to allow for substantially equal illumination of the target. In addition, the present specification is a beam chopping apparatus that is lightweight and does not cause an X-ray source assembly employing the beam chopper to become heavy and difficult to deploy. | 12-01-2011 |
