    Piston Ring Pressure Distribution (1943)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The discovery and introduction of the internal combustion engine has resulted in a very rapid development in machines utilizing the action of a piston. Design has been limited by the internal components of the engine, which has been subjected to ever increasing thermal and mechanical stresses, Of these internal engine components, the piston and piston rings are of particular importance and the momentary position of engine development is not seldom dependent upon the development of both of the components, The piston ring is a well-known component and has been used in its present shape in the steam engine of the last century, Corresponding to its importance, the piston ring has been a rich field for creative activity and it is noteworthy that in spite of this the ring has maintained its shape through the many years. From the many and complicated designs which have been suggested as a packing between piston and cylinder wall hardly one suggestion has remained which does not resemble the original design of cast iron rectangular ring.

    Experimental Investigation of a Model of a Two-Stage Turboblower (1943)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: In the present paper an investigation is made of two stages of a multistage turboblower having a vaneless diffuser behind the impeller and guide vanes at the inlet to the nest stage. The method employed was that of investigating the performance of the successive elements of the blower (the impeller, vaneless diffuser, ets.) whereby the kinematics of the flow through the blower could be followed and the pressure at the different points computed. The character of the flow and the physical significance of the loss coefficients could thereby be determined so as to secure the best agreement of the computed with the actual performance of the blower. Since the tests were carried out for various delivery volumes, the dependence of the coefficients on a number of factors (angle of attack, velocities, etc.) could be obtained. The distribution of the losses that occur during the transformation of dynamic pressure at the impeller exit into static pressure could be found and likewise the range within which the friction coefficient varies in the vaneless diffuser. With the aid of factors having a certain physical significance, the centrifugal blower could be computed on the basis of a more or less schematical consideration of the phenomena occuring during the air flow through it, and the use of arbitrary factors and recourse to the geometrical similtude law thus avoided. The present investigation largely summarizes all the previous work af the CHI Blower Section on the different elements of a centrifugal blower. Some considerations on the analysis of model test data for application to full-scale are presented in the appendix.

    The Coupling of Flexural Propeller Vibrations with the Torsional Crankshaft Vibrations (1943)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: The exact mathematical treatment of the problem is possible by replacing the propeller blade by a homogeneous prismatic rod. Conclusions can them be drawn as to the behavior of an actual propeller, since tests on propeller blades have indicated a qualitative agreement with the homogeneous rod. The natural frequencies are determined and the stressing of the systems under the various vibration modes are discussed.

    Notes: Im wasserreichen Teil des Systems Al2O3/SO2/H2O kristallisieren beim Abkühlen Eis bzw. SO2-Hydrat aus; das von beiden Stoffen gebildete Eutektikum erstreckt sich weit in das ternäre System hinein. Konzentriert man Aluminiumsulfitlösungen bei Raumtemperatur, z. B. durch Eindunsten über P2O5 im SO2-Strom, so kristallisiert ein  -  formal „neutrales“  -  Sulfit der Formel Al2O3·3SO2·xH2O aus. Einige Eigenschaften der neuen Verbindung werden beschrieben und ihre Bildungsbedingungen untersucht.

    Notes: Es wurde festgestellt, daß die Autoxydation des Tricyclohexylbleis auch in Lösung nur bei geeigneter Belichtung vor sich geht. Die hiernach erforderliche Aktivierung R3Pb → R3Pb* findet durch Na-Licht nicht statt. Die Kurve der Lichtabsorption des (C6H11)3Pb enthält weder im Sichtbaren noch im Ultraviolett charakteristische Absorptionsmaxima. Dem Gesamtverlauf der Autoxydation entspricht quantitativ praktisch die Formulierung Anstatt eines Peroxydes konnte nur (C6H11)3PbOPb (C6H11)3, das in gleicher Weise weiter reagierte, als Zwischenprodukt gefaßt werden.
