20100132910 | Method For Detecting And Classifying Surface Defects On Continuously Cast Slabs - A method for the detection and classification of surface defects on continuously cast products using topographical information about the appearance of continuously cast surface defects and/or flaws are determined with respect to their exact position, evaluated with respect to their location and dimensions, and eliminated in accordance with the evaluation prior to further machining of the product, or are prevented by optimizing the process. The defects and/or flaws on the slab surface of the continuously cast preliminary product are detected and are stored with respect to their exact position and a detection of defects and/or flaws on the finished product is carried out and stored with respect to their exact position, and in that the information from the preliminary product is then compared with the information from the surface inspection on the finished product. Only the information which has led to, or can lead to, defects on the finished product is considered for the elimination of defects and/or flaws on the preliminary product. | 06-03-2010 |

20090262473 | Self-protecting crowbar - The invention relates to a protective circuit for an electrical device operated in particular in an explosion-hazard area, with a limiting circuit connected downstream of a pair of input terminals for limiting an output voltage present at a pair of output terminals and/or an output current delivered at the output terminals below a threshold value and a shorting circuit, which shorts the output or input terminals when a threshold value is exceeded, the control signal that controls the limitation originating from the same place as the signal that triggers the shorting circuit, and with a measuring circuit, which uses the output voltage or the output current to provide a control signal, which is fed on the one hand to a final control element for reducing the output voltage or the output current and on the other hand to the shorting circuit, the measuring circuit comprising a ZENER diode and/or a measuring resistor and the control signal being a voltage that is in particular a transistor-amplified or impedance-converted voltage. To minimize the difference between the guaranteed output voltage and the safety voltage, the invention proposes that the final control element is a self-conducting field-effect transistor, at the gate of which the control signal is present, and the measuring circuit is connected downstream of the field-effect transistor in the direction of current flow. | 10-22-2009 |
