Optimum Band Width for Two Layer Anti-Reflection Films

R. Muchmore1948-01-01Journal of the Optical Society of America

To determine the reflection from a two layer anti-reflection film on glass the ideas and terminology of network analysis are introduced. Those parts of network theory to be used are briefly reviewed. This theory is shown to provide a clear physical picture of the field changes which occur with varying film parameters.…

Reactions of Carbon and Metal Oxides in a Vacuum

W. J. Kroll、A. W. Schlechton1948-01-01Journal of The Electrochemical Society

The literature on the reactions of carbon and metal oxides in a vacuum is reviewed and the results of an experimental study of the reduction of several metal oxides by carbon in a vacuum are reported. None of the refractory oxides studied were stable in contact with carbon in a vacuum at temperatures above 1380°C. Oxi…

Sintered Plates for Nickel-Cadmium Batteries

Arthur C. Fleischer1948-01-01Journal of The Electrochemical Society

Porous plaques are prepared by sintering carbonyl nickel powder of low apparent density. The plaques are impregnated with nickel or cadmium salt solutions and the heavy metal ions precipitated in the pores of the plaque by cathodic polarization in alkali hydroxide solution. Sintered plates made by this procedure have…

Abstract La propriété fortement réductrice d'une solution ammoniacale du dioxyde de thiourée ne peut pas être attribuée à la formation passagère du sel d'ammonium de l'acide sulfoxylique, car les éthers éthyliques de cet acide, en solution alcaline, ne précipitent pas les sels de cadmium à l'état de cadmium métallique…

The crystal structure of glutaric and pimelic acid. Alternation of properties in the series of dicarboxylic acids

C. H. MacGillavry、G. Hoogschagen、F. L. J. Sixma1948-01-01Recueil des Travaux Chimiques des Pays-Bas

Abstract Glutaric acid and pimelic acid have analogous crystal structures. The CH 2 chains are stretched along the c‐axis, the plane of the zigzag is nearly parallel to (100). Packing of the COOH groups is practically identical to that in adipic acid. This packing enforces a torsion in the molecules of the odd acids a…

Diskrete Energieverluste mittelschneller Elektronen beim Durchgang durch dünne Folien

Gerhard Ruthemann1948-01-01Annalen der Physik

Mit der verschärften magnetischen Halbkreismethode hohen Auflösungsvermögens wurden die Energieverluste von 2 bis 8 ek Volt-Elektronen nach dem Durchgang durch sehr dünne Folien (100—500 ÅE Dicke) von Kollodium, Al2O3, Be, Al und Ag untersucht. Es ergab sich: 1 In den Geschwindigkeitsspektren fanden sich für jede Foli…
