    摘要: An electrode for electrolysis purposes, which may in particular be used as an anode for the electrolysis of alkali metal chlorides, contains, in addition to an alloy of niobium with a metal of the iron group, tantalum, tantalum carbide or an alloy of tantalum with metals of the iron group, individually or as mixtures. The surface of the electrode is modified with a metal of the platinum group, especially with rhodium.

    摘要: Blue iron hexacyanoferrate-III pigments are produced by a process wherein complex iron-II hexacyanoferrate-II (Berlin white) is prepared by electrolysis of an aqueous catholyte solution containing (a) an iron-II salt, (b) an alkali metal salt, an ammonium salt or a mixture of these, and (c) hydrogen cyanide, in an electrolysis cell in which the anode chamber and cathode chamber are separated by an ion exchange membrane, using an electrically conductive aqueous liquid in the anode chamber, and the iron-II hexacyanoferrate-II obtained is then converted to the blue pigment.The process gives Berlin white, which is substantially free from salt, in high yield and high purity. Pollution caused by the process is very low, since only a small amount of salt is produced. Compared with the corresponding blue pigments produced by prior art processes, the pigments obtained give purer colorations with better gloss, and are of higher color strength.

    摘要: A delivery drum includes at least one supporting shell for supporting a printed sheet and for producing a vacuum region between the supporting shell and the printed sheet. The supporting shell extends over the entire width of the printed sheet. A circumferential length, which is at least one quarter of the sheet length of the printed sheet, is disposed between the sheet start of the printed sheet and the start of the vacuum region.
