    Notes: Diels-Alder-Reactions. IX. On the Formation and the Thermolysis of Isomeric TricyclopentadienesThe formation of isomeric tricyclopentadienes by codimerisation of cyclopentadiene with endo- and exo-dicyclopentadiene between 100 and 140°C in the liquid phase, and the retrodiene reaction of the main isomeres of the tricyclopentadiene fraction by gas phase thermolysis were studied kinetically between 230 and 310°C. The rate constants and the parameters of activation were determined.

    Notes: Saccharomyces cerevisiae CBS 426 was grown aerobically in continuous culture with a mixture of glucose and ethanol as the carbon source. The flows of biomass, glucose, ethanol, oxygen, and carbon dioxide were measured. A model for growth with two substrates was derived. Application of this model to the above-mentioned system yielded values for YATP and P/O. The joint confidence regions for these parameters were calculated. The relevance to industrial production of bakers' yeast is discussed.

    Description / Table of Contents: Relationship Between Composition, Elastic Modulus and Creep of Phenolic Plastics at Room TemperatureThe mechanical properties of thermosetting material can be modified by the type and quantity of filler or the combination of fillers. By this methode it is possible to produce a certain moulding powder for a certain application. The elastic modulus and the creep are significant values for short-time and long-time mechanical behaviour. The relationship between these both characteristic values and the compositions of moulded materials (multiphase phenolic resin systems) will be discussed.
    Notes: Die mechanischen Eigenschaften duroplastischer Teilchenverbundwerkstoffe können unter anderem durch die Wahl des Harzträgers beeinflußt und somit dem jeweiligen Anwendungsfall angepaßt werden. Für das mechanische Kurz- bzw. Langzeitverhalten sind der E-Modul und die Kriechdehnung als signifikant anzusehen, daher wird am Beispiel dieser beiden Werkstoffdaten der Zusammenhang von Formstoffzusammensetzung und mechanischen Eigenschaften aufgezeigt. Die untersuchten Phenoplast-Formstoffe bestehen aus den Hauptkomponenten Harz/Holzmehl/Gesteinsmehl.

    Description / Table of Contents: The Swelling Behaviour of Thermosetting MaterialsThe moisture absorption of moulded materials can endanger a construction because of the change in volume of various parts. Therefore it is necessary to know the maximum possible swelling of the moulded materials employed at different relative humidities. The swelling of modified phenolic resin systems are described. Wood flour (which absorbs moisture) and powdered minerals (which in this case can be considered as inert) were used as fillers.Different methods have been developed to calculate the maximum possible swelling after a relatively short testing time (ca. 1000 h).
    Notes: Die Feuchteaufnahme eines Formstoffes kann durch die damit verbundene Volumenänderung des Formteils die Funktion einer Baugruppe gefährden. Daher muß die maximal mögliche formstoff- und umgebungsfeuchtespezifische Quelldehnung der eingesetzten Formstoffe bekannt sein. Am Beispiel von Ein-, Zwei- und Dreistoffsystemen mit Phenolharz als Matrixwekstoff wird der Einfluß der Harzträger Holzmehl (im Hinblick auf die Feuchteaufnahme „aktiv“) und Gesteinsmehl („inaktiv“) auf die Quellung untersucht. In diesem Zusammenhang werden Methoden aufgezeigt, die eine Abschätzung der maximal möglichen Quelldehnung nach relativ kurzer Versuchsdauer (etwa 1000 h) ermöglichen.

    Analysis of nitrated polycyclic aromatic hydrocarbons by glass capillary gas chromatography using different detectors (1982)
    Weinheim : Wiley-Blackwell

    ISSN: 0935-6304
    Keywords: Gas chromatography, glass capillary ; Selective detection ; Nitrated polycyclic aromatic hydrocarbons ; Carbon black ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Glass capillary gas chromatography has been investigated as a method for the analysis of nitrated polycyclic aromatic hydrocarbons (nitro-PAH) using both splitless and on-column injection techniques. The nitro-PAH showed good chromatographic performance and thermal stability under the GC conditions used. Retention times and response factors of several nitro-PAH were compared to those of conventional PAH.Simultaneous flame ionization and thermionic nitrogen selective detection was used to facilitate identification of nitro-PAH in complex samples. The feasibility of the method is demonstrated on two samples of commercial carbon black. Besides 1-nitropyrene several isomeric dinitropyrenes have been identified.

    Möglichkeiten zur Lebensdauervorhersage durch Eigenspannungsmessungen an einem wechselbeanspruchten austenitischen Stahl (1980)

    Description / Table of Contents: X-Ray Stress Measurement on Austenitic Steels - A Possibility of Predicting Fatigue DamageBased on the results found for fatigue tests on a ferritic steel combined with x-ray stress analysis similar investigations were carried out for an austenitic stainless steel. For that reason the Wöhler tests were interrupted after defined load cycle numbers and the residual stress and the half value breadth of the x-ray peaks were determined in the groove of the samples. The investigation has shown correlations between residual stress, load amplitudes and load cycle numbers. These relations in connection with a dependence of the breadth of the x-ray peaks from the load cycle number have been used for a non-destructive testing model of predicting the life of samples under alternating load.
    Notes: Aufbauend auf Untersuchungen an einem ferritischen Stahl wurden an Proben aus einem austenitischen Stahl Ermüdungsversuche kombiniert mit Eigenspannungsmessungen durchgeführt. Dazu wurden die Wöhlerversuche definiert nach vorgegebenen Lastwechselzahlen unterbrochen und röntgenografisch die Eigenspannungen und Interferenzbreiten im Kerb der Proben bestimmt. Es zeigten sich Abhängigkeiten der Oberflächeneigenspannungen von Lastamplituden und Lastwechselzahlen, die unter Zuhilfenahme der ebenfalls gefundenen Zusammenhänge zwischen Halbwertbreiten und Lastwechselzahlen dazu herangezogen werden, um auf zerstörungsfreiem Wege auf die Lebensdauer wechselbeanspruchter Proben zu schließen.

    Description / Table of Contents: The Effect of Moisture on the Mechanical Properties of Phenolic Moulded MaterialsIn order to use thermosetting moulding material it is necessary to know how the mechanical properties are changed by absorption of water. Therefore, multiphase systems based on phenolic resin, with varying quantities of wood flour and/or powdered minerals as fillers, were examined. The relationship between moisture absorption and the change in Young's modulus, flexural strength and the strain of the outer fibre at fracture was determined. It could be shown that the increase in flexural strength as water absorption began is a result only of the swelling stress.
    Notes: Voraussetzung für den Einsatz duroplastischer Formstoffe in erhöhter Umgebungsfeuchte ist die Kenntnis der durch die Feuchteaufnahme bewirkten Änderung der mechanischen Werkstoffeigenschaften. Ausgehend von in ihrer Zusammensetzung variierten Mehrstoffsystemen auf der Basis Phenolharz/Holzmehl/Gesteinsmehl wird die formstoff- und feuchtespezifische Wechselwirkung zwischen Feuchteaufnahme, Biege-E-Modul, Biegefestigkeit und Randfaserdehnung beim Bruch aufgezeigt, und nachgewiesen, daß der zu Lagerungsbeginn zu beobachtende Anstieg der Biegefestigkeit ausschließlich auf durch Sorption hervorgerufene Druck-Eigenspannungen zurückzuführen ist.
