    Description / Table of Contents: Contents Using numerical methods, the eddy current distribution is calculated in a conducting wedge induced by two exciting wires located symmetrical to the wedge. The complex equationsystem is solved by the relaxation-method of Gauß-Southwell and the solution is verified for the case of a conductiong semispace.
    Notes: Übersicht Für den Fall der symmetrisch zu einem leitenden Keil angeordneten, gegensinnig von sinusförmigem Wechselstrom durchflossenen Doppelleitung, wird mit Hilfe numerischer Methoden die Wirbelstromverteilung im Keil berechnet. Das entstehende komplexe Gleichungssystem wird nach dem Relaxationsverfahren von Gauß-Southwell gelöst und die Ergebnisse für den leitenden Halbraum kontrolliert.

    Notes: Abstract We have studied the influence of oxygen on the superconducting properties of thin films of lead, indium and tin deposited on glass or sapphire substrates. In addition, the morphological microstructure was investigated by scanning electron microscopy. The film thickness was 1.0 μm, and the partial pressure of O2 during the film deposition was raised up to 1×10−4 Torr. In all three materials the development of a granular structure and a strong increase in the residual electric resistivity was observed due to the O2-treatment. Whereas in the Pb films no change of the critical temperature was found, the In films deposited on glass substrates showed a slight increase ofT c due to the oxygen. The strongest increase ofT c (up to 8%) was observed in the O2-treated Sn films. These results are discussed in terms of the McMillan theory. From our measurements of the critical current densityj c we conclude that edge pinning is dominant in the undoped films. All three materials showed a strong increase ofj c due to the O2-treatment which must be interpreted in terms of bulk pinning.

    Description / Table of Contents: Die Gelchromatographie kann als eine netzwerk-limitierte Verteilung aufgefaßt werden. Dies führt zu dem Schluß, daß keine normierende Eichbezeichnung, zwischen Molekulargewicht und Elutionsvolumen existiert, die ausschließlich, der gelösten Substanz abhängige Parameter enthält.Die Darstellung von Gelen mit unterschiedlicher chemischer Struktur wird be schrieben, und die Möglichkeiten, die Porengröße zu variieren, werden diskutiert. Die Untersuchung des Einflusses der physikalischen und chemischen Struktur auf die Trennung und die Trennleistung zeigte, daß das Elutionsvolumen durch die chemische Natur des Gels beeinflußt wird; die Trennleistung wird hingegen im wesentlichen durch die physikalische Struktur bestimmt.
    Notes: Gel chromatography can be considered as a network-limited partition. This leads to the conclusion that it is impossible to find a generalizing relationship between the molecular weight and the elution volume using parameters depending only on the solute.The preparation of gels with different chemical structure is discussed and possible methods for the alteration of pore size are described. Investigations of the influence of the physical and chemical structure on separation and separation efficiency have shown that the elution volume depends to some extent on the chemical nature, but the separation efficiency is mainly a function of the physical structure.

    Notes: The cationic polymerization of 1,3,5-trioxane in methylene dichloride with boron trifluoride, producing polyoxymethylene, was investigated. An ionogenic cocatalyst is not required in this polymerization. During the induction period, initially formed, short polyoxymethylene chains depolymerize to formaldehyde until a constant equilibrium concentration of formaldehyde is reached. This concentration is equal to the ceiling concentration of formaldehyde in cationic polymerization under the conditions chosen for the experiments. The nonstationary state and the strong acceleration of the polymerization of trioxane are due mainly to the lack of an effective kinetic termination reaction. Thus the concentration of growing polyoxymethylene cations increases with time.
