Sur la structure des solutions aqueuses de carboxymethylcellulose
Abstract Nous avons étudié deux carboxyméthylcelluloses ayant à peu près les mêmes caractéristiques moléculaires. Leur comportement rhéologique très différent s'explique par le fait qu'elles contiennent des proportions très différentes d'une fraction gonflant fortement dans l'eau mais insoluble. Cette fraction est par…
Effect of Adsorbed Polar Organic Compounds on Activity of Steel in Acid Solution
A series of aliphatic acids, amines, and esters, as well as one commercial corrosion inhibitor, were adsorbed from benzene solution onto SAE 1020 steel powder. These studies (reported elsewhere) showed that some portion of the sorbed material, depending on the compound, could not be desorbed by fresh solvent. The pres…
Calcium Halophosphate Phosphors
The energy distribution of the emission spectra of a number of calcium halophosphate phosphors has been determined on a recording spectroradiometer. These emission curves have been broken down into component bands, each of which has a Gaussian distribution of energy against wave number. An attempt is made to assign th…
Thermionic Emission from Oxide Cathodes: Retarding and Accelerating Fields
An experimental investigation of the thermionic emission from oxide-coated cathodes is presented in which the applied voltage range extends from the retarding potential region through zero field and up to an average accelerating field of 50,000 volts per cm. The retarding potential range yields information concerning…
The design of metallic delay dielectrics
A theory of metallic delay dielectrics, which is more accurate than existing ones and is based on an analogy with shunt-loaded transmission lines, has been developed for the simplest case, when the delay medium consists of an array of infinitely long conducting strips. Formulae have been obtained for the refractive in…

Mechanics of Elastic Performance of Textile Materials
Stress-analysis methods for textile materials are illustrated through a study of the forces pro duced when a continuous-filament yarn is stressed in tension. It is shown that the effects of yarn twist and yarn size on the tensile properties of singles continuous-filament yarns depend upon the stress distribution. Math…

Effect of Calcination on Natural Pozzolans
Calcination will improve the quality of some pozzolans, reduce the quality of others, and induce pozzolanic properties in some otherwise essentially non-reactive-substances. Natural pozzolans or natural materials in which pozzolanic properties can be induced by calcination at temperatures less than 2000 F. owe their a…

The ionic conductivity of Li‐halide crystals
Abstract The ionic conductivity of mixed crystals of Li halides and Mg halides has been measured. From these measurements the mobility of Li vacancies and the concentration of vacancies in pure Li halides has been derived, with the two assumptions that the defects in Li halides are Schottky defects and the mobility of…
Wide-Angle Metal-Plate Optics
The design equations for constrained metal-plate lenses are derived. These lenses prove to have exceptional wide-angle scanning properties. The scanning aberrations are investigated by means of a power series expansion of the phase error. This analysis indicates that the square-law error is a function of lens depth an…
