    Notes: Einleitend wird auf den grundsätzlichen Aufbau und das Frequenz-Einsatzgebiet der verschiedenen Schwingungserreger eingegangen. Die wirtschaftliche Bedeutung kommt dem niederfrequenten Bereich zu. Zum Unterschied von Rührwerken treten bei Vibrationen starke Beschleunigungskräfte auf, deren Auswirkung besonders bei heterogenen Systemen von Interesse ist. Neben einer von der Frequenz abhängigen Mindest-Amplitude ist für das Fördern und Klassieren die mehr oder weniger elastische Reflexion des Materials auf seiner Unterlage verantwortlich.

    Phasen-Grenzlinien, insbesondere in ihrer Bedeutung für die Korrosion (1951)

    Description / Table of Contents: Phase boundary-lines, especially in their impotance for corrosionTwo phases have a common cleavageplane, whilst three phases touch one another along a boundary line only. Corroesponding to an adsorption in the first case in an adlineation in the second case. Both processes diminish the free energy and herewith the activity of the boundary, so inhibiting the possibilities of corrosion.Local elements, glow cathodes and catalysts consisting of several components are typical systems acting at microscopic boundary-lines. Cavitation is the inverse phenomenon.Macroscopic boundary-lines in partially filled containers, formed by wall, liquor and gaseous phase, are about this especially active, as being mixed with a four-phases-point-system, that results from the heterogeneity of the container wall. Gravity potentials, and electrokinetic potentials have their maximum value in the boundary-lines too.
    Notes: Zwei Phasen haben eine gemeinsame Grenzfläche, während drei Phasen sich nur entlang einer Grenzlinie berühren. Der Adsorption im ersten Falle entspricht eine Adlineation im zweiten Falle. Beide Vorgänge setzen die freie Energie und damit die Aktivität der Grenze herab, hemmen also Korrosionsmöglichkeiten.Lokalelemente, Glühkathoden und Mehrstoff-Katalysatoren sind typische Systeme, die an mikroskopischen Grenzlinien zur Wirkung kommen. Kavitation bildet die inverse Erscheinung hierzu.Makroskopische Grenzlinien an teilgefüllten Behältern, die durch Wandung, flüssigem Inhalt und gasförmiger Phasegebildet werden, sind darüber hinaus besonders aktiv, da sie von einem Vierphasen-Punktsystem durchsetzt sind, das infolge er heterogenität der Behälterwand resultiert.Gravitationspotentiale und elektrokinetische Potentiale haben ebenfalls in den begrenzenden Linien ihren maximalen Wert.

    Decomposition kinetics of a phenolic-carbon composite. I. Resin available for volatilization (1970)

    Notes: The isothermal decomposition of a phenolic resin in a phenolic-carbon cloth composite was measured at approximately 0.1 to 0.2 torr over the temperature range of 105°-718°C. The kinetics are initially first order and, in the later stages, second order. An analytic technique is provided for calculating the maximum quantity of resin which will volatilize during decomposition, thereby obviating the necessity of measurements for extended time periods. The amount of resin available for volatilization during decomposition varies with temperature and is in equilibrium with resin, which does not volatilize. Plots of the equilibrium constant versus the reciprocal absolute temperature show that two equilibria are involved: one which predominates up to 352°C and the other above this temperature. The heats of reaction are 2.2 and 15.3 kcal/mole. The first value is associated with hydrogen bonding and the second with decomposition and oxidation activation energies.

    Decomposition kinetics of a phenolic-carbon composite. II. Rate relationships (1971)

    Notes: The isothermal decomposition of a phenolic resin in a phenolic-carbon cloth composite was measured in air at 0.1 to 0.2 torr over the temperature range 104-718°C. Two decomposition rate relationships are presented that can be used to predict decomposition. One assumes two second-order consecutive rate-controlling reactions, and the other assumes a diffusion-limited second-order reaction. Two rate constants govern each relationship, one being operative during the initial decomposition stages, and the other during the final stages. Evidence is presented to support the applicability of both relationships to predict decomposition over the entire temperature range studied. Arrhenius plots of the rate constants consist of several segments linearly connected. Activation energies and frequency factors computed from these segments cover a broad range of values. The activation energies are used to correlate the temperature ranges with the predominant products formed in these ranges.

    Preparation and stress-strain properties of SBS and SIS block polymers made with dilithium initiators (1972)

    Notes: ABA-type block polymers of styrene (monomer A) and isoprene or butadiene were prepared using two commercially available dilithium adducts of isoprene as initiators. One (DiLi-1) was predominantly dilithio diisoprene and contained a small amount of dimethyl ether (ether/Li 〉 1.0). The second (DiLi-1 C.E.) was a higher molecular weight version of DiLi-1, containing about seven isoprene units per molecule. It contained only a trace of dimethyl ether (ether/Li 〈 0.1). Polymers were made by charging all of the monomers at the start of the reaction. The diene polymerized first, incorporating some styrene. When the diene was consumed, the difunctional polymer chains then added a block of nearly pure polystyrene at each end. Thus an ABA-type polymer was synthesized in one step. These polymers show the usual behavior of pseudo-vulcanized elastomers. Their stress-strain curves are given. The SBS polymers had the higher tensile strengths. None had tensile strengths as high as SBS or SIS polymers made with n- or sec-butyllithium. It was shown that the diene blocks contain appreciable amounts of styrene. This leads to more compatibility between the A and B blocks; it also shortens the styrene blocks compared to the theoretical lengths of “pure” blocks. Both effects can lead to loss of tensile strength. Microstructures of the diene homopolymers made with these initiators are also given.

    Description / Table of Contents: The Surfaces Energy of Stable MaterialsAn explanation of the basic meaning and importance of interfacial surface forces in the building up of materials is followed by an examination of the manysided relations between the surface energy and the other properties of solid materials. The relationships between the tensile strength and other mechanical values, the importance of capillary pressure in active fillers and in separation hardening, the place of synthetic materials in the “Paracher Diagram”, their relation to the specific entropy and others factors are examples of this. Some actual numerical values for surface tension of metals in the solid state, inorganic compounds and synthetic materials are mentioned. However, most of these values depend on empirical methods of calculation.
    Notes: Nach einer Darlegung über die grundsätzliche Bedeutung der Grenzflächenkräfte für den Aufbau der Stoffe wird auf die vielseitigen Bezichungen zwischen Oberflächenenergie und anderen Eigenschaften kompakter Materie eingegangen. Zusammenhänge mit der Zerreißfestigkeit und anderen mechanischen Güteziffern, Bedeutung des Kapillardruckes bei aktiven Füllstoffen und bei der Ausscheidungshärtung, die Lage der Kunststoffe im „Parachor-Diagramm“, ihre Beziehung zur spezifischen Entropie u. a. sind Beispiele hierfür. Ferner werden Zahlenwerte für die Oberflächenspannung im festen Zustand von Metallen, anorganischen Verbindungen und Kunststoffen angeführt, die auf verschiedenen meist empirischen Berechnungsverfahren beruhen.
