Abstract Based on the work of Eyring and others relating to the creep problem, a velocity-modified temperature is developed for representing by means of a single variable the combined effects of strain rate and temperature on the stress reaction in a tension specimen. Available data are analyzed, indicating that the v…
Abstract Natural and synthetic rubber can be vulcanized with several vulcanizing agents other than sulfur, though sulfur and sulfur compounds are the only agents of practical value. A combination of rubber and synthetic resin can be successful only when chemical bonds are formed. It has been found that this is the cas…

Abstract This and a following article review the literature from 1910–1945 on polymerization of olefins and diolefins in suspension and emulsion, and present a number of new measurements not published to date. The subject is considered mainly from the point of view of scientific information on the mechanism of polymer…
Measurements have been made of all the elastic, piezoelectric, and dielectric constants of KDP and ADP crystals through temperature ranges down to the Curie temperatures. The piezoelectric properties agree well with Mueller's phenomenological theory of piezoelectricity provided the fundamental piezoelectric constant i…

In this article an attempt is made to examine the goals of current and of possible future types of research concerned with the non-elastic deformation of metals. It is found that an understanding of non-elastic deformation would be enhanced by research upon the following topics: 1. The anelasticity associated with the…
electric accelerating fields are to be obtained.by replacing the usual "dee" assembly and acceleration chamber by a cavity resonator, similar to types now commonly employed in radar.The use of such a cavity becomes practical only in an iron-less device, because of the limitation imposed by the air-gap in present accel…
Les auteurs présentent une étude systématique des spectres Raman de nombreuses molécules pentatomiques tétraédriques appartenant aux différents groupes de symétrie possibles. Beaucoup n'avaient pas encore été décrits; les autres ont été l'objet d'une étude critique. Les auteurs ont pu ainsi établir un classement plus…
Abstract Bei einer aus vielen starren Fadenelementen bestehenden Molekel wird die statistische (wahrscheinlichkeitselastische) Rückstellkraft sehr gross, sobald die Fadenelemente praktisch vollständig gegeneinander ausgerichtet sind. Es ist daher vorauszusehen, dass bei Einwirkung von Kräften, welche zu einer weitgehe…
The storage field of diaphragms in wave guides is usually described in terms of higher-order evanescent waves. Yet a rectangular wave guide may be thought of as a strip transmission line, which is continuously stub-supported at both edges, and one would not normally describe the storage field of a condenser or coil sh…

Abstract Calculations have been made of the lattice distortion at the free crystal surface of the cube face of alkali halide crystals on the basis of Born's lattice theory, with the result that the displacement of the positive surface ions in a direction perpendicular to the surface differs considerably from that of t…
The factors which determine image contrast in optical and electron micrographs are discussed in relation to a new metal shadow-casting technique whereby the contrast of images is greatly increased by depositing obliquely a thin film of metal on the microscope preparations. Further advantages of the use of shadow-casti…

A review is given of measurements of the thermal conductivity of natural clothing fibres and of formulae that have been proposed for the overall thermal conductivity of fibre-air mixtures in terms of their density and fibre conductivity. Measurements of the conductivity of wool felts ranging in density from 0.01 to 1.…
