    Notes: The nonohmic behavior of carbon black-loaded natural rubber viilcanizates was studied. Three samples contained high-abrasion furnace black (HAF) in good, moderate, and poor dispersion. Another sample contained a good dispersion of medium thermal black (MT). The nonohmic behavior of the poor HAF dispersion and that of the MT dispersion could be interpreted as due to internal field emission acroM insulating gap widths of 2 and 2.5 μ. The existence of such gaps waa confirmed by electron micrographs. No clear evidence of internal field emission could be obtained for the good and moderate HAP dispersions where, according to electron micrographs, the gaps are much narrower. There is some indication that the degree of diapersion can be correlated with field emission characteristics.

    Description / Table of Contents: Increased stress on the steel structure in the vicinity of the groundWith a steel structure, the coatings near the ground are more exposed to corrosion than other areas of the structure, due to snow, ice, splashing water and dirt deposits which absorb moisture. To obtain uniform protection for all surfaces, it is desirable to strengthen the zone in the vicinity of the ground by an additional coat, preferably of a bituminous type.
    Notes: Die Bodenzone der Anstriche an einer Stahlkonstruktion ist durch Schnee, Eis, Spritzwasser, Schmutzablagerungen, die Feuchtigkeit absorbieren usf., stärker beansprucht als der Anstrich an den anderen Flächen der Konstruktion. Urn eine gleichmäßige Schutzwirkung an allen Flächen zu gewährleisten, ist eine Verstärkung der Bodenzone durch einen zusätzlichen Anstrich, möglichst auf bituminöser Basis, zweckmäßig.

    Kanten-, Schrauben- und Nietkopfschutz (1962)

    Description / Table of Contents: Protection of edges, bolt and rivet headsThe thickness at the edges and at the screw and rivet heads is much smaller than on the rest of the surface. This is due to the tendency of the coatings, because of their surface tension, to avoid the edges, and also to the “shaving” effect of the brush during the treatment. Thus, if the coating on the main surface has a thickness of 100 to 125 microns, that at the edge has one of 25 to 75 microns. The inadequacy at these points is compensated by an additional coat, consisting of an edge protection coating which, because of its composition, does not show the same tendency to flow away from the edges; this coating is applied intermediately between primers and top coats.
    Notes: Die Schichtdicke eines Korrosionsschutzanstriches ist von ausschlaggebender Bedeutung für die Lebensdauer eines Anstriches.Die Schichtdicke an den Kanten, Schrauben-und Nietköpfen ist im Vergleich zur Fläche wesentlich geringer. Dies ist bedingt durch die sog. Kantenflucht der Anstrichmittel auf Grund ihrer Oberflächenspannung und durch das „Abrasieren“ mittels des Pinsels bei der Verarbeitung. So beträgt bei einer Schichtdicke der Fläche von 100 bis 125 μ, die Schichtdicke an der Kante 25 bis 75 μ. Die an diesen Punkten nicht ausreichende Schichtdicke wird durch einen zusätzlichen Anstrich zwischen den Grund- und Deckanstrichen mit einem Kantenschutzanstrichmittel, das auf Grund seiner Zusammensetzung keine Kantenflucht zeigt, gestrichen.

    Notes: Azulene was totally deuterated by treatment with bariumoxide in heavy water at high temperature. The exchange reaction of azulene-d8 in methanol with picric acid is shown to produce an azulene-d6 of definite structure, which is very likely to be azulene-d6-(2,4,5,6,7,8). Infrared spectra of the two hitherto unknown compounds in carbontetrachloride solution are given, together with those of azulene-d2-(1,3) and undeuterated azulene. The electronic absorption spectra of the deuterated compounds in cyclohexane show a systematic hypsochromic shift of frequencies.

    Notes: The viscosity behavior of a high molecular weight fraction (M̄w = 9.8 × 106) of dextran (B-512) in aqueous solutions was studied at low and medium shear stresses, and its intrinsic viscosity was shown to be independent of shear stress. A convenient and precise multibulb Ubbelohde-type viscometer, especially designed for use with aqueous solutions is described. The calibration of the viscometer and the evaluation of surfacetension corrections of relative flow times measured in it are discussed in detail.

    Shear dependence of the reduced viscosity - concentration slope constant (1962)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Polymer Science 57 (1962), S. 209-225 
    Details
    ISSN: 0022-3832

    Topics: Chemistry and Pharmacology , Physics
    Notes: The variation with shear of the concentration dependence of the reduced viscosity was studied in the system polystyrene-toluene at 20, 40, and 60°C. The slope constant k′ was determined at constant shear stress k′T and at constant shear rate k′D; k′T was found to increase, k′D to decrease, with increasing shear. Alternatively, the concentration dependence was expressed in terms of Peterlin's effective viscosity. For this system the effective viscosity at constant shear stress was independent of shear but the effective viscosity at constant shear rate decreased with shear. The decrease in k′D, and in effective viscosity at constant shear rate with shear are attributed to molecular entanglement and an explanation is proposed for the observed differences in behaviour at constant shear stress and constant shear rate. In appendices a new formula for the calculation of viscosity ratios from the relative flow times is derived, and a procedure is outlined to compute intrinsic viscosities and limiting slope constants that will be free from absorption effects.
