In order to control weeds in sugar beet cultures consisting of tolerant or resistant mutants or transgenic sugar beet plants, herbicide combinations (A)+(B), optionally in the presence of safeners, are particularly suitable, said combinations having an active content of: (A) herbicides exhibiting broad-spectrum effectiveness from group (A1) glufosinate(salts) and allied compounds; (A2) glyphosate(salts) and allied compounds such as sulfosate and (A3) imidazolinone or the salts thereof; and (B) herbicides from the group consisting of (B0) one or more herbicides structurally different from the above-mentioned group (A) or (B1) herbicides exhibiting activity against monocotyledonous or dicotyledonous weeds with an effect on the foliage and primarily on the soil or (B2) herbicides having primarily an effect against dicotyledonous weeds and (B3) herbicides having primarily an effect on the foliage and that can be used against monocotyledonous weeds, or (B4) herbicides having an effect on both the foliage and the soil and which can be used against monocotyledonous weeds or from herbicides from several groups consisting of (B0) to (B4), and the sugar beet cultures tolerant to herbicides(A) and (B) contained in the combination, optionally in the presence of safeners. Optionally, said combinations are also suitable for growth regulation or for influencing the yield or the constituents of sugar beet plants.

The invention relates to a method for recovering cobalt and copper from a cobalt-containing copper concentrate in a pyrometallurgical treatment process. Blister copper is formed in a suspension smelter and/or converter, and is conveyed to an anode furnace, and the slag that is formed is fed together with a reductant into a slag cleaning furnace. Blister copper is obtained from the slag cleaning furnace, and this is also routed to the anode furnace to produce anode copper. The slag from the slag cleaning furnace is routed to a cobalt recovery furnace, to which sulphide-containing material is also conveyed, in addition to a reductant. Cobalt is recovered from the cobalt recovery furnace matte and the slag that is formed is waste slag.

The invention relates to a suspended file (10, 110) having an envelope element (12) for receiving flat objects, preferably documents, and having holding elements (30) which have hooks (32), are arranged at a spacing from one another and can be moved between a holding position, in which, for being hooked into holding rails, the hooks (32) project beyond two side edges (20) of the envelope element (12) which extend at a spacing from one another, and a withdrawn position, in which the hooks (32) are withdrawn at least partially in the direction of the side edges (20), wherein the envelope element (12) has at least one receiving pocket (26) which extends between the side edges (20), is open towards the latter and in which a rigid reinforcing rail (28) is received which extends at least over a large part of the length of the receiving pocket (26) and to which the holding elements (30) are connected movably. There is provision according to the invention for the holding elements (30) to bear in each case in sections flatly against the reinforcing rail (28) and, during movement, to slide with one of their side faces on a side face of the reinforcing rail (28).

The invention relates to a method for colouring a metal part (1) that makes it possible to associate the colour of the parts (1) to the dimensions thereof. The method is implemented by: a first step that comprises cleaning the part (1) for preparing the surface thereof for oxidation; and a second step that comprises oxidising the part (1) for colouring the same. The method is characterised in that the cleaning is interrupted before the dimensions of the part (1) are modified. The method of the invention makes it possible to obtain a part having predetermined dimensions in a simple and reproducible manner.

The invention relates to optical coherence tomography (OCT), more specifically to spectral optical coherence tomography (SOCT). The invention deals with problem of artefacts occurring in certain scan positions due to sharp increases of reflection by the object under investigation. It solves this problem by using an extra intensity sensor located at an output for non-dispersed light of the dispersive element used for spectral analysis, e. g. in the zero order of a diffraction grating, and using the signal of this sensor for the modification of the interferometric data.
