    摘要： An oxygen blowing lance for steel production, the lance having a protection element. The end of a main oxygen tube at the lance head has a cover shell with outlets. An oxygen outlet nozzle is removably and exchangeably fastened to each outlet. The protection element is provided removably and exchangeably at the lance head end of the oxygen blowing lance. An intermediate space is present between the lance head end of the oxygen blowing lance and the protection element. Penetrations are provided in the protection element, the oxygen outlet nozzles passing through the penetrations from the shell outward, and a gap remains between the oxygen outlet nozzle and the protection element. A protective gas line feeds into the intermediate space between the lance head end of the oxygen blowing lance and the protection element. A method for operating the oxygen blowing lance is also described.

    摘要： In a method for determining the position of an object relative to the background with ultrasound, a plurality of ultrasound transducers arranged in a row simultaneously transmit ultrasound in line-shaped fashion in the direction of an object scene and receive both the echo of the signal transmitted by the transducer itself as well as the echoes of the signals generated by the neighboring ultrasound transducers. On the basis of a reference measurement wherein no object is located in the measurement region, the amplitudes and the times of incidence of the echo signals are stored. In the following measurements with an object, the echo amplitudes and the times of incidence of the echo signals are again stored and compared by fuzzy logic to those of the reference measurement. As a result, this supplies the position of the object relative to the background.

    摘要： A holder for eyeglass lenses having a holding part, which is magnetically secured to the fastening part in detachable fashion and has a nose bridge for holding eyeglass lenses, and having at least one swivel bearing, which is provided between the fastening part and the nose bridge of the holding part and has at least two bearing parts that are able to swivel relative to each other around the swivel axis of the swivel bearing in order to move the holding part between a use position of the eyeglass lenses and a non-use position of the eyeglass lenses in which they are folded upward in relation to the use position. In order to embody a holder of the above-mentioned type in a reliable and simply designed way, the first bearing parts and second bearing parts are embodied so that they are detachable from each other and are held together magnetically, for which purpose, at least one bearing part has at least one permanent magnet with a magnetization direction oriented in the direction of the swivel axis.
