    Description / Table of Contents: Reaction Primer and Metal PaintingThe complex reactions which take place when reaction or wash primers are applied to metallic surfaces lead to the formation of an insoluble surface layer, which combines with the basic metal and the subsequent coats of paint that are applied to it. There are many different ways in which reaction primers can be made up and their composition depends upon the nature and properties of the metallic surface to be protected. The latest developments and experiences with these “metallic wanderers” are recorded.
    Notes: Die komplexen Reaktionen, die bei Auftrag von Reaktions- oder Wash-Primer/ auf Metall ablaufen, führen zur Bildung einer unlöslichen metallorganischen Deckschicht, die zugleich mit dem Grundmetall und den nachfolgenden Anstrichschichten „verwächst“. Der Aufbau von Reaktionsprimer ist vielfach verschieden und richtet sich auch nach der zu schützenden Metallart. Es werden neuere Erfahrungen mit diesen “Metallwandlern“ mitgeteilt”.

    Description / Table of Contents: On the Corrosion of iron resulting from Temperature Differences of the ElectrolytesThe article investigates the dependence of corrosion on differences in temperature, such as are encountered in the chemical industry. Iron electrodes immersed in neutral KCL solutions of varying temperatures will form a “corrosion element”, wherein the iron in the colder solution forms the cathode and that in the warmer solution forms the anode. The addition of KNO3 causes the iron in the colder solution to act as the cathode, whilst that in the warmer solution becomes the anode. This behaviour is traced back to the formation of thin yet visible covering layers on the iron in the KNO3 solution.With electrolytic concentrations of approximately 〉 0,1 n-(KCl + KNO3) currents are induced. These currents are of such a magnitude that they are able to protect the cathode almost completely from the effects of local corrosion.
    Notes: Die Abhängigkeit der Korrosion von Temperaturdifferenzen, wie sie in chemischen Apparaturen und Industrieanlagen auftreten, wird untersucht. Eisenelektroden in neutralen KCL-Lösungen verschiedener Temperaturen lassen sich zu elektrochemischen Korrosionselementen zusammenschließen, bei denen das Eisen in der kälteren Lösung die Kathode, in der wärmeren Lösung die Anode ist. Durch Zusatz von KNO3 wird das Eisen in der kälteren Lösung zur Anode, in der wärmeren Lösung zur Kathode. Das unterschiedliche Verhalten wird auf die Ausbildung dünner, aber sichtbarer Deckschichten auf dem Eisen in der wärmeren KNO3-Lösung zurückgeführt.Bei Elektrolytkonzentrationen etwa 〉0,1 n-(KCL + KNO3) treten Stromdichten auf, die so groß sind, daß sie die Kathode praktisch vollkommen vor Lokalkorrosion schützen können.

    Description / Table of Contents: Cerium-Cerium Alloys and Cerro alloysThe article opens with a brief historical survey of the production of cerium and cerium alloys, particular attention being paid to the manufacture of gas mantles and flints for lighters. A 99,92-99,93% pure metal is obtained by electrolysis or by the treatment of Cerium Cloride or Cerium Fluoride with Sodium or Lithium. Cerium plays an important part in the production and working of spheroidal cast iron, as a protective agent and as a catalyst. It si of particular value in various smelting processes, since it has a pronounced deoxydizing effect. The second part of the article is devoted tot he various cerium alloys, several of which are noteworthy for their very low melting point (47,2°C).
    Notes: Zunächst wird ein kurzer geschichtlicher Überblick über die Herstellung von Cer und Cerlegierungen gegeben, wobei besonders die Gasglühlichtindustrie und die Fabrikation von Zündmetall für Feuerzeuge berücksichtigt wird. Durch Schmelzflußelektrolyse oder durch Umsetzung von Cerchlorid bzw. Cerfluorid mit Natrium oder Lithium wird ein Metall in 99,92-99,93%iger Reinheit erzeugt. Cer spielt u. a. bei der Herstellung und Verarbeitung von Sphäroid-Gußeisen, zum Schutz von Werkstücken, also Katalysator, eine beachtliche Rolle. Für die Schmelztechnik ist es von besonderem Wert, da es sehr stark desoxydierend wirkt. Der zweite Teil der Arbeit ist den verschiedenen Cerrolegierungen gewidmet, von denen sich einige durch einen sehr niedrigen Schmelzpunkt (47,2°C) auszeichnen.
