Abstract: The invention relates to a method for increasing the wear resistance of a metal screen cloth made of wire, the method comprising treating a surface of a metal screen cloth by means of a thermochemical surface layer method for increasing the surface hardness and the wear resistance of metals, wherein the thermochemical surface layer method changes the structural conditions of the treated metal to a predetermined depth of penetration, wherein a hard surface layer is formed in the metal surface. A corresponding device and a screen cloth and a screen panel with increased wear resistance are also part of the invention.

Abstract: The invention relates to a method for correcting the zoom setting and/or the vertical offset in an image assembled from two sub-frames of a stereo film, wherein the one sub-frame is provided by a first camera of a camera rig and the second sub-frame is provided by a second camera of the camera rig, wherein a vertical offset is changed via a change in the pitch setting, wherein, during the operation when recording the stereo film, a difference between the present zoom-results in the first sub-frame relative to the second sub-frame is measured and/or a vertical offset of the image points present in the first sub-frame in relation to those corresponding image points in the second sub-frame is measured and, on the basis of this information, correction values are calculated, with which the zoom difference and/or the vertical offset is reduced, given appropriate application to the zoom and/or pitch setting.

Abstract: A metal halide lamp with ceramic discharge vessel (4), the discharge vessel having two ends (6) that are sealed with stoppers, and an electrically conducting lead-through (9) being guided through these stoppers (12), there being fastened on the lead-through an electrode (15) with a stem (16) that projects into the interior of the discharge vessel, lead-through and electrode together being designated as an electrode system. The lead-through being a niobium pin, and the electrode stem (16) consisting of two pins, a pin made from tungsten being arranged situated on the inside on the discharge side, and a pin made from molybdenum being arranged on the outside on the discharge side and having a length of 3 to 8 mm.

Abstract: A metal halide lamp having a ceramic discharge vessel with two ends which are closed off by stoppers, and an electrically conductive leadthrough guided through this stopper. An electrode with a shank secured to the leadthrough, which electrode projects into the interior of the discharge vessel. The leadthrough and electrode referred to as an electrode system, comprises two components, which are designed as pins of different diameter, the larger component being a niobium pin and the smaller component, which adjoins it on the inner, discharge side, being a pin made from molybdenum or tungsten which is fitted in a bore in the niobium pin.
