    摘要: A process for the preparation of alkyleneimines by subjecting sulfuric acid monoesters of aminoalkanols to an at least two-stage reaction with aqueous bases at a temperature of at least 110° C. under pressure, relieving the pressure of the reaction mixture and distilling off the alkyleneimines from the reaction mixture after each reaction stage, wherein the conversion in the first stage is from 40 to 90% and that in the second stage is from more than 90% to 99.99%.

    摘要: A process and system for separation of foreground information from background information in a document is described. In an initial stage, at least two images of a document are created, each with different filtering. One of the images is filtered so that only foreground information, or fragments thereof, remain. This image serves as the initial image for subsequent image restoration, while the remaining images represent reference images for the image restoration. In a second stage, the image restoration is carried out so that as much as possible of the foreground information which was lost by filtering from the initial image is restored again. By comparing information from the initial image with information from at least one reference image, the information remaining in the initial image is supplemented by foreground information from at least one reference image. Information to be supplemented from a reference image is selected with the aid of a suitable selection method such as for example, an adjacent point method. Individual areas of specific size are imposed around information points which possess foreground information content in the initial image, as well as in each of the reference images. The method adds information points from a reference image to the initial image to restore original foreground information content but not restore background information.

    摘要: A device for operating an electronic circuit at a high-voltage potential includes a diode array installed in a high-voltage line, wherein a current is configured to flow over the high-voltage line through the diode array. A voltage drop over the diode array is applied to the electronic circuit, which is configured to provide information ascertained on the high-voltage line. An evaluation unit connected to the electronic circuit via a galvanically separated transmission device receives the information from the electronic circuit.
