20080289503 | Method and Device for Welding Metallic Fibers Into a Fleece by Repeatedly Carrying out a Welding Process, Fleece Having Welded Metallic Fibers and Method of Filtering Exhaust Gas With a Fleece - A method and a device produce a fleece of metallic fibers in a layer in which the metallic fibers are welded to one another to form the fleece. A welding process is repeatedly carried out with regard to a portion or section of the fleece. Such metallic fiber fleeces are used, in particular, for exhaust gas treatment units in the automobile industry. | 11-27-2008 |
20090013659 | Apparatus and Method for Discontinuous Welding of Metallic Fibers, Method for Filtering Exhaust Gases and Exhaust-Gas Treatment Component - An apparatus and a method for welding metallic fibers to form a knitted fabric having a predetermined width, include feeding a composite of metallic fibers to an apparatus for welding the fibers to form a knitted fabric, and separately welding a plurality of partial sections of the composite in a time period, in which the composite is at a standstill, for example through the use of a plurality of welding electrode pairs which are disposed over the width of the composite. A method for filtering exhaust gases and an exhaust-gas treatment component are also provided. | 01-15-2009 |

20150377105 | METERING VALVE FOR ADDITIVES AT RISK OF FREEZING - A metering valve having a valve housing, a channel, a valve body that can be moved in order to open and close the metering valve, and a spring, which applies a spring force to the valve body and thus keeps the valve body in a rest position. The spring is supported on at least one calibration body. The valve body, the spring, and the at least one calibration body are arranged in the channel, and the at least one calibration body is supported by a supporting component fastened in the valve housing by a material-bonding connection. A segment of the supporting component protrudes from the valve housing. | 12-31-2015 |
