    Description / Table of Contents: Dynamic strength variationThe Weibull probability function or the arcsin √P distribution suffices for description purposes provided that considerations are confined to failure or survival probabilities between 20 and 80%. Beyond these limits more sophisticated analysis of the test results - as too in the case of the design engineer when estimating the statistically induced component of the safety margin - must make use of more realistic distribution functions.
    Notes: Zu ihrer Beschreibung genügt die Weibullsche Wahrscheinlichkeitsfunktion oder auch die arcsin P-Verteilung nur, solange man sich auf Ausfall- oder Überlebenswahrscheinlichkeiten zwischen 20 und 80% beschränkt. Jenseits dieser Grenzen muß sich die anspruchsvollere Analyse der Versuchsergebnisse - wie auch der Konstrukteur bei der Abschätzung der statistisch bedingten Komponente der Sicherheitsspanne - wirklichkeitsnäherer Verteilungsfunktionen bedienen.

    Notes: Trichlormethyl-trifluorsilan wurde mit Antimon(III)-fluorid. Diphenylantimon(III)-fluorid, Triphenylbleifluorid und Phenylquecksilberacetat umgesetzt. Unter Abspaltung von SiF4 bildeten sich meist unbeständige Trichlormethylmetallverbindungen, die in die entsprechenden Schwermetallchloride übergingen. In reiner Form konnten Trichlormethyl-diphenylantimon(III) 2 und Trichlormethyltriphenylblei 3 abgetrennt werden.

    Notes: Nach den von Hirschfelder angegebenen Formeln wurden die Selbstdiffusionskoeffizienten, die Zähigkeit und die Wärmeleitfähigkeit einiger Gase und die binären Diffusionskoeffizienten von Gaspaaren zwischen 0 °C und 1000 °C berechnet und durch einen Potenzansatz approximiert. Die hierbei erhaltenen Parameter werden angegeben und die auftretenden Fehler diskutiert.

    Notes: The electron-impact and field ionisation spectra of nineteen di- and tetracyanopyrazines are presented. The use of high resolution mass measurement and metastable analysis allows the proposal of some general fragmentation mechanisms. The 5,6-disubstituted (alkyl or arene) 2,3-dicyanopyrazines examined show, apart from a less important loss of the nitrile and dicyano groups, fragmentation of the heterocyclic system directed by the nitrogen atoms. In contrast, anellation in the 5,6-position, leads only to loss of the nitrile and dicyano groups being observed. These general fragmentation mechanisms are also observed for the tetracyanopyrazines examined. A comparison of di- and tetracyanobenzene with five ring heterocycles containing four cyano groups shows that fragmentation of nitrile groups is greatly dependent upon the aromaticity of the cyclic system.

    Description / Table of Contents: Barium salts react with SbF3, solutions to give the slightly soluble Ba[SbF5]; in the case of Ba carbonate and hydroxide, also antimony oxide and oxide fluoride, respectively, are precipitated.Nickel carbonate gives with SbF3 solutions an easily soluble tetrafluoroantimonate(III) Ni[SbF4]2 · 6 H2O, crystallizing as emerald-green prisms of hexagonal habitus. With CaCl2, only the precipitation of antimony oxide-containing CaF2, was observed.Salts of the acid H[SbF3OH] could not be obtained in this manner.
    Notes: Bariumsalze bilden in SbF3-Lösungen schwerlösliches Ba[SbF5]; mit Bariumcarbonat und -hydroxid fallen daneben Antimonoxid bzw. -oxidfluorid aus.Nickelcarbonat ergibt ein leicht lösliches, in smaragdgrünen, sechsseitigen Säulen kristallisierendes Fluoroantimonat Ni[SbF4]2 · 6 H2O; als Nebenprodukt wird oftmals schwer lösliches Nickelfluorid gebildet. Mit CaCl2 fällt ausschließlich antimonoxidhaltiges CaF2, aus. Salze der von Schiemann(2) vermuteten Säure H[SbF3OH] konnten nicht gefunden werden, was aber ihr Vorkommen nicht ausschließt.

    Description / Table of Contents: The IR spectra of several methyllead sulfinates, sulfonates and sulfates and of lead methanesulfonate and lead methanesulfinate have been investigated. Assignments are given. The spectra supply evidence for the ionic constitution of the methyllead compounds.
    Notes: Die IR-Spektren von verschiedenen Methylbleisulfinaten, -sulfonaten und -sulfaten sowie von Bleimethansulfonat und Bleimethansulfinat wurden aufgenommen und die wichtigsten Banden zugeordnet. In allen Fällen sind den Spektren Hinweise für den salzartigen Charakter der Verbindungen zu entnehmen.

    Description / Table of Contents: Mass spectra of positive and negative molecule ions from organo-triptych-siloxazolidines (silatranes) support the assumption that in the silatranes a coordinative covalent bond exists between nitrogen and silicon, the latter being thus pentacovalent. From such alkyl and aryl compounds silver alkyls and aryls, respectively, may be prepared which, however, quickly decompose under formation of elemental silver. The alkoxy compounds, on the other hand, yield with AgNO3 silver oxide as a primary product. Starting from silatranes, however, it is possible to obtain stable organo-Hg, -Sb, -Bi, and -Pb compounds.
    Notes: Molekelmassenspektren positiver sowie negativer Ionen stützen die Annahme, daß bei Organotriptych-siloxazolidinen (Silatranen) zwischen dem Stickstoff und dem dadurch pentacovalenten Silicium eine koordinativ-covalente Bindung besteht. Mit den Alkyl- und Arylverbindungen können Silber-Alkyle und-Aryle dargestellt werden, die aber rasch unter Abscheidung von elementarem Silber zerfallen. Die Alkoxyverbindungen ergeben mit Silbernitrat dagegen zunächst Silberoxid. Mit Hilfe der Organo-triptychsiloxazolidine lassen sich aber beständige Organoquecksilber-, -antimon-, -wismut-und -bleiverbindungen darstellen.
