20090305075 | METHOD FOR PRODUCING LOW-SPRINGBACK HALF SHELLS - A method for producing low-springback half shells made of a metal, in particular steel or a steel alloy, includes drawing in at least one drawing die a blank, such that the blanks have flange regions on the deep drawn body after the deep drawing. The flange regions are shaped by upsetting a corner substantially perpendicularly to a wall of the deep drawn region of the blank and the flange regions are subsequently trimmed in a shearing die, such that half shells without margins are produced. | 12-10-2009 |
20100133724 | Method and device for producing highly dimensionally accurate flanged half shells - A method for producing highly dimensionally accurate, deep-drawn half shells with a base region, a body region and a flange region, includes firstly forming a pre-formed half shell from a blank and then shaping the pre-formed half shell into a finally formed half shell, wherein the pre-formed half shell has excess blank material due to its geometric shape and wherein, owing to the excess material during the shaping of the pre-formed half shell into its final shape the half shell is compressed into the finally formed half shell by at least one further pressing process. The method requires that the pre-formed half shell has excess blank material in a transition region between the body region and flange region. | 06-03-2010 |
20110162431 | Partially reinforced hollow profile - A method for producing partially reinforced hollow profiles made of a metal, particularly steel, or a steel alloy includes forming a blank, together with a plurality of reinforcing metal elements arranged on the blank, into a hollow profile using the rolling-in technique or by means of U-O forming, wherein after forming the reinforcing elements arranged on the blank are connected to the formed blank at least by means of a positive interengagement. This method provides a simple and cost-effective procedure for producing reinforced hollow profiles made of metal. | 07-07-2011 |

20110198508 | Method for Noise Correction for a Flat-Panel Detector - For noise correction in connection with a flat-panel x-ray detector, noise signals of a dark reference area are checked for deviations exceeding a specified threshold which, if any are present, will be taken into consideration separately for calculating the correction factor derived from the noise signal. Image artifacts due, for example, to high-contrast objects such as, for instance, cardiac pacemakers or metallic implants, in the x-ray image will be avoided through this measure. | 08-18-2011 |
