| 20080232665 | Method for noise reduction in digital images with locally different and directional noise - A method is disclosed for noise reduction in images with locally different and directional noise, in particular for noise reduction in image data records of computed tomography. In at least one embodiment of the method, two image data records of an identical object region that have mutually independent noise are provided. The two image data records are decomposed by a discrete wavelet transformation into a number of frequency bands, detailed images having high frequency structures being obtained in at least two different directions. Noise images in the respective frequency bands and directions are obtained by subtracting a wavelet coefficient of the two input images. These noise images are used to estimate noise locally and as a function of direction, and on the basis of this estimate local threshold values are calculated and applied to the averaged wavelet coefficients of the input images. A result image with reduced noise is obtained after an inverse wavelet transformation. | 09-25-2008 |

| 20110274335 | Method for recording and reconstructing a three-dimensional image dataset and x-ray apparatus - A method for recording and reconstructing a three-dimensional image dataset is proposed. A plurality of projection images are acquired under different recording geometries in relation to an object to be recorded by an X-ray apparatus, in particular a C-arm X-ray apparatus. At least two projection images are recorded for at least one recording geometry, in particular for every recording geometry. The three-dimensional image dataset is reconstructed from the project images. | 11-10-2011 |

| 20100291981 | CORN COB CLEANING SYSTEM - A cleaning system for corn cobs incorporating a conveyor system providing a capability for positively removing or cleaning other crop residue from the cobs, which is adapted to be towed by a harvester; to be incorporated with a cob collecting device; and which can be adjustable for varying corn varieties, conditions and the like. The conveyor system includes at least one enclosed inclined conveyor for carrying a flow of the crop residue upwardly and propelling the flow into a space, while a flow of air is directed downwardly along the conveyor to remove other residue material from the cobs. Another flow of air is optionally directed downwardly through the space for removing additional material other than cobs, and at least one aspect of the system can be adjusted for relatively varying the air flows to adapt the system for a variety of conditions. | 11-18-2010 |
| 20110034222 | CORN COB CLEANING CONVEYOR SYSTEM - The cob cleaning conveyor system provides a capability for positively removing or cleaning lighter crop residue from a flow of cobs. The system can be incorporated with a cob collection device, such as on a trailer, and can be adjustable in several ways for accommodating varying corn varieties, conditions and the like. The system includes a first conveyor which propels the flow into a gap or passage toward a second conveyor, while a flow of air is directed downwardly through the passage to remove or clean the lighter residue material from the cobs. The angle of attack of the air flow can be selectable, and optionally be directed downwardly along the second conveyor to the passage, and upwardly along the second conveyor to travel with or follow the residue flow, to suit present conditions. | 02-10-2011 |

| 20090122945 | Fuel Assembly for a Pressurized-Water Nuclear Reactor - A fuel assembly for a pressurized water nuclear reactor contains a multiplicity of fuel rods which are guided in a plurality of axially spaced spacers which in each case form a square grid, composed of grid webs, with a multiplicity of cells arranged in rows and columns. In each case one control rod guide tube is guided through a number of these cells. At least one spacer is configured to be mechanically stronger in a first partial region than in a second partial region. In this second partial region, the spacer is provided with at least one resisting element which protrudes into a flow sub-channel formed between the fuel rods and increases the flow resistance. The resisting element counteracts a reduction associated with the mechanically weaker configuration, in the flow resistance in the second partial region and in this manner effects a homogenization of the hydraulic behavior of a spacer which is mechanically inhomogeneous on account of the varying mechanical configuration. | 05-14-2009 |
