    Description / Table of Contents: On the Corrosion of Wine Bottle aps Made of Thinly Tinned Lead (Tinfoil Caps) and their TestingSeveral method have been developed for the testing of the thickness and porosity of the tin layers of the customary tinfoil caps. The tin layers of commercial wine bottles were found to be less than 0,001 mm and for a great part considerably porous.To test the resistance of the caps to corrosion, laboratory experiments and practical storage tests have been carried out with commercially capped bottles. Under certain conditions which might be met in practice the caps were corroded considerably, and in some cases they were deteriorated totally. The corrosion products are lead salts.
    Notes: Es wurden Verfahren für die Prüfung der Dicke und der Porigkeit der Zinnauflage auf den üblichen sogenannten “Stanniol” - Flaschenkapseln entwickelt. Kapseln von aus dem Handel bezogenen Weinflaschen waren fast stets unter 0,001 mm dick verzinnt und meist erheblich porig.Zur Prüfung der Korrosionsbeständigkeit der Kapseln wurden Laboratoriumsversuche mit Kapseln und praktische Lagerversuche mit handelsüblich verkapselten Flaschen ausgeführt. Unter gewissen Bedingungen, die in der Praxis durchaus vorkommen können, wurden die Kapseln unter Bildung von Bleisalzen erheblich korrodiert, in einigen Fällen sogar völlig zerfressen.

    Description / Table of Contents: On the Anodic behavior of copper zinc alloys in sodium cyanide solutions IThe solubility of alloyed metal anodes is conditioned by the potential of the most not noble constituent of the alloy and the solubility of te cover primary formed on the surface of this constituent. Zinc and brass could be passivated much more easily tan copper. Both the constituents of the alloy react indepently just loke the pure metals. α + β bras is more active and can not be passivated as easily as α-brass. There are only gradual differences between the corrosion processes as well as between the reactions of anodic solution or passivation. The two metals dissolve one after the other and get passivated iin a process consisting of two steps. The voltage of the alloy shows the existence of a small depolarizing effect of teh metals upon one another.
    Notes: Die Löslichkeit von Legierungsanoden wird durch das Potential des unedelsten Bestandteiles der Legierung und die Löslichkeit der sich auf diesem Bestandteil primär ausbildenden Deckschicht bestimmt. Zink und Messing ist leichter zu passivieren als Kupfer. Beide Bestandteile reagieren in der Legierung unabhängig voneinander ähnlich wie die reinen Metalle, α + β-Messing ist aktiver und daher schwerer zu passivieren als α-Messing. Zwischen den Korrosionserscheinungen sowie den Vorgängen bei der anodischen Auflösung oder Passivierung der Legierungsanode bestehen nur graduelle Unterschiede. die beiden Metalle geben nacheinander in Lösung und werden in zwei Stufenprozessen passiv. Die Potentiale der Legierung zeigen eine geringe depolarisierende Wirkung der beiden Einzelmetalle aufeinander.

    Description / Table of Contents: Polythylene plastic pipesPipes of soft and hart polythylene (Supralen soft and supralen hard) are gaining increasing application in constructions for transport of aggressive liquids and gases because of their good properties especially owing to their resistance to corrosion. So this paper presents a general and up to date survey of the commercial types and their dimensions and of the physical (mechanical, thermal, electric, hydraulic, acoustic, optical properties) and corrosion chemical behavior as well as te installation and fitting of polythylene pipes.
    Notes: Rohre aus Weich- und Hartpolyäthylen (Supralen, weich und Supralen, hart) finden infolge ihrer guten allgemeinen und spezifischen Eigenschaften, insbesondere ihres ausgezeichneten korrosionschemischen Verhaltens, zunehmende Verwendung in Anlagen zur Förderung aggressiver Flüssigkeiten und Gase. Im Hinblick darauf gibt der vorliegende Fortschrittsbericht einen zusammenfassenden und zeitgemäßen Überblick über Lieferarten und Dimensionierung, über das physikalische (mechanische, thermische, elektrische, hydraulische, akustische und optische Eigenschaften) und korrosionschemische Verhalten sowie über die Verlegung und Verbindung von Polyäthylen-Plastikrohren.

    Description / Table of Contents: On an method for removal of boiler scaleThe solid incrustations in boilers etc. are removed usually by application of certain acids at those places of the devices where the incrustations have been formed. It is wellknown that the aggressive effect of the acids upon cleaned metal surfaces could be prevented by an addition of certain substances with inhibitive effect which will say that these substances decrease or even prevent acid attacks. The peper contains a report on the inhibitive effect of the „Brindi“-resin and some theoretical conclusions drawn from the experimental results.
    Notes: Feste Steinbildungen in Kesseln usw. werden in neuerer Zeit bekanntlich da-durch beseitigt, daß sie in den Anlagen, in denen sie sich gebildet haben, durch bestimmte Säuren gelöst wurden. Es ist auch bekannt, daß die aggressive Wirkung der Säuren auf die Metallflächen, die unter den Steinbildungen liegen, wenn letztere aufgelöst sind, dadurch verhütet wird, daß der Säure bestimmte Stoffe zugesetzt werden, die als Inhibitoren wirken, d. h. den Säureangriff verringern oder u. U. ganz verhüten. Im vorliegenden Aufsatz ist die diesbezügliche Wirkung des „Brindiharzes“ als Inhibitor laboratoriumstechnisch festgestellt und versucht worden, aus den Ergebnissen einige theoretische Folgerungen zu ziehen.
