    Notes: Essentially the entire surface of the U. S. Air Force B-58 supersonic bomber is aluminum-bonded panel construction. Primary as well as secondary structural bonded panels were designed and manufactured to operate under demanding service conditions which include high stress, subzero temperature, high temperature, and severe acoustical vibration. Smooth surfaces are an additional requirement at subsonic and supersonic speeds. These requirements demanded that bonded joints in the B-58 be carefully designed and thoroughly evaluated. Joints in the B-58 were designed by “empirical procedures,” established for a specific adhesive syetem. Large numbers of test panels were required to confirm panel integrity and establish allowables for design. The development and adoption of accurate theoretical technique for predicting joint streqgths has been pursued and can be expected to reduce both the cost and the amount of testing required to achieve reliable deign with adhesives.

    Description / Table of Contents: Causes of scale formationContinuous operation of many appliances is impeded by scale formation which is most frequently encountered on heat transmitting surfaces. The present article deals with crystalline scale formed by dissolved substances on metallic materials.A theoretical section, dealing with the influence on scale formation of such factors as pressure, temperature, extraneous matter, flow velocity and condition of the solid surface, is followed by the description of experimental investigations.The phenomenon investigated as a model is the crystallisation in radioactively marked CaSo4 solution (Ca45 and S35, respectively). The experiments show, in keeping with the theory, that macroscope scale can only appear when the solution is over-saturated. There are no essential differences as between corrosive and non-corrosive materials, the formation of blisters on the solid surface tends to promote scale formation. In this connection, the roughness of the solid surface is likewise of importance. The experimental results give rise to certain practical conclusions.
    Notes: Durch die Verkrustung, die insbesondere and wärmeübertragenden Oberflächen auftritt, ist ein Dauerbetrieb mancher Apparate nur begrenzt möglich. Die vorliegende Arbeit behandelt kristalline Krusten, wie sie sich aus gelösten Stoffen an metallischen Werkstoffen bilden.Nach einem theoretischen Abschnitt, in dem der Einfluß des Druckes, der Temperature, fremder Stoffe, der Strömungsgeschwindigkeit der Lösung sowie der Zustand der festen Oberfläche auf die Krustenbildung diskutiert wird, werden experimentelle Untersuchungen beschrieben.Als Modellvorgang ist die Kristallisation aus radioaktiv markierten CaSo4- Lösungen (45Ca bzw. 35S) untersucht, Die Versuche zeigen in Übereinstimmung mit der Theorie, daß makroskopische Krusten erst bei einer übersättigten Lösung entstehen können. Wesentliche Unterschiede liegen zwischen korrodierenden und nicht korrodierenden Werkstoffen vor. Blasenbildung an der festen Oberfläche erhöht die Krustenbildung. Hierbei ist auch die Rauhigkeit der festen Oberfläche von Bedeutung. Aus den Versuchsergebnissen werden schließlich Folgerungen fü die Praxis gezogen.

    Description / Table of Contents: Using auto-radiograms for the investigation of phenomena on metal surfacesFor the examination of boundary layer phenomena on solid surfaces, radio-active isotopes can be used with advantage. In this connection, the local distribution of radiating matter can be ascertained with the aid of auto-radiograms.The present article deals with the use of auto-radiograms for studying the separation and adsorption phenomena on metal surfaces. Special attention is paid to the influence of grain boundaries, displacements and orientations of the crystallites as well as the influence of macroscopic roughness on the adsorption of aqueous electrolyte solutions. The tests were carried out with β radiating isotopes 147 Pm and 204 T1.The auto-radiograms show that any zones of disturbance and any inhomogeneities on a solid metal surface are the first to be covered with radio-active substance. It is, for instance, found that increased adsorption takes place at grain boundaries and points of displacement. It is also shown that the separation is influenced by the orientation of the crystallites. The test results give rise to the conclusion that auto-radiograms can also be used for the clarification of other boundary layer phenomena.
    Notes: Zur Untersuchung von Grenzflächenvorgängen an festen Oberflächen werden mit Vorteil radioaktive Isotope eingesetzt. Die örtliche Verteilung des strahlenden Materials kann man dabei mit Hilfe der Autoradiographie feststellen.Die vorliegende Arbeit beschreibt die Verwendung der Autoradiographie beim Studium von Abscheide- und Adsorptionsvorgängen an Metalloberflächen. Insbesondere wird hier der Einfluß von Korngrenzen, Versetzungen und Orientierungen der Kristallite sowie makroskopischen Rauhigkeiten auf die Adsorption aus wäßrigen Elektrolytlösungen behandelt. Die Versuche wurden mit den β-strahlenden Isotopen 147Pm und 204T1 durchgeführt.Aufschlußreiche Autoradiographien zeigen, daß jede Störstelle und jede Inhomogenität an einer festen Metalloberfläche bevorzugt mit radioaktiver Substanz belegt wird. So beobachtet man z. B., daß an Korngrenzen und Versetzungen eine verstärkte Adsorption auftritt. Ferner wird gezeigt, daß die Orientierung der Kristallite die Abscheidung beeinflußt. Die Versuchsergebnisse weisen darauf hin, daß auch andere Grenzflächenvorgänge mit der Autoradiographie geklärt werden können.

    Notes: A method for the determination of heat of hard-rubber reaction by the application of differential thermal analysis is reported. The heat of reaction was determined with stocks containing different rubber/sulfur ratios and also with a 68/32 stock, preheated to contain different amounts of combined sulfur. Heat evolution is observed first with samples containing about 7% sulfur and therefrom the amount of heat evolved shows a nearly linear increase up to 30% sulfur. With increasing combined sulfur in the 68/32 stock, the quantity of exothermic heat gradually diminishes; so also does the temperature of initiation, i.e., the temperature at which heat evolution appears to begin. Initiation of exothermic reaction appears to be a function of composition and temperature of the mass. An increase in the rate of reaction was observed when the composition reached 0.5 g.-atom of sulfur per isoprene unit. An endothermic dehydrogenation reaction is observed at the end of the hard-rubber reaction. This, however; does not affect the determination of exothermic heat, because there is similar dehydrogenation taking place in the reference material (ebonite) which almost balances this heat loss. The final product has a lower sulfur content due to loss of sulfur as hydrogen sulfide.
