Properties of water-repellent fabrics

John W. Rowen、Davide Gagliardi1947-01-01Journal of research of the National Bureau of Standards

A review and an a nalys is of the t heor y of water repellency of textile fab ri cs have been made. The physicochemical basis underl ying the we ttability, or wa ter repe llency, of t reated fabrics is di sc ussed. A survey of the laborator y test methods for e valuating water repe lle ncy of tex til e fabri cs is pre…

Sur la possibilité d'existence d'un type particulier de radioactivité phénomène de création e

Raymond Daudel、Maurice Jean、Marcel Lecoin1947-01-01Journal de physique

Dans cet article, on montre la possibilité théorique d'existence d'un type nouveau de désintégration β. On étudie, en se plaçant toujours d'un point de vue entièrement théorique, les particularités qui caractériseraient le phénomène.

Stress Induced Preferential Orientation of Pairs of Solute Atoms in Metallic Solid Solution

Clarence Zener1947-01-01Physical Review

In a non-stressed cubic crystal the axes of pairs of adjacent solute atoms are randomly orientated along the several permissible crystallographic directions. It is shown that in the presence of a stress the equilibrium orientation is no longer random, but that certain directions become preferred, and it is further sho…

THE CATALYTIC ACTION OF ALUMINIUM SILICATES: I. THE DEHYDRATION OF BUTANEDIOL-2,3 AND BUTANONE-2 OVER ACTIVATED MORDEN BENTONITE

A. N. Bourns、R. V. V. Nicholls1947-01-01Canadian Journal of Research/Canadian journal of research

The dehydration of butanediol-2,3 over activated Morden bentonite has been investigated. Below 350 °C., liquid products butanone-2, isobutyraldehyde, and the isobutyral of butanediol-2,3 were produced. Butanone-2 was obtained in 86% yield. At higher temperatures, 450° to 700 °C., gaseous decomposition occurred. Only s…

Derivative Crystal Structures

Μ. J. Buerger1947-01-01The Journal of Chemical Physics

There exists a class of crystal structures which are derived from others by generalization. These are here designated derivative structures. A special case of derivative structure is the popular ``superstructure.'' The symmetry of a derivative structure is a subgroup of the symmetry of the basic structure. Here the te…

Absorption of Water by Films of Cellophane and Polyvinyl Alcohol

E. Creutz、Robert R. Wilson1946-12-01The Journal of Chemical Physics

The absorption of water and dehydration of these films is found to obey a diffusion equation by means of which a diffusivity may be defined. This is not a constant but depends on the water concentration in the foils. A rapid change in water content immediately after changing the ambient conditions suggests the presenc…

Magnetoresistance and Domain Theory of Iron-Nickel Alloys

R. M. Bozorth1946-12-01Physical Review

Measurements of change of electrical resistivity with magnetization and with tension are reported for iron-nickel alloys containing 40 to 100 percent nickel. When the magnetostriction is negative (81 to 100 percent nickel), tension ($\ensuremath{\sigma}$) decreases resistivity, and magnetic field ($H$) increases it. D…

Investigation of Oxidation of Copper by Use of Radioactive Cu Tracer

J. Bardeen、W. H. Brattain、W. Shockley1946-12-01The Journal of Chemical Physics

A very thin layer of radioactive copper was electrolytically deposited on a copper blank. The surface was then oxidized in air at 1000°C for 18 minutes, giving an oxide layer with a thickness of 1.25×10−2 cm. After quenching, successive layers of the oxide were removed chemically, and the copper activity in each layer…

Stress-Time-Temperature Relations in Polysulfide Rubbers

Miriam Stern、A. V. Tobolsky1946-12-01Rubber Chemistry and Technology

Abstract Polysulfide rubbers of various internal structures have been investigated by measurements of continuous and intermittent relaxation of stress and by creep under constant load at temperatures between 35° C and 120° C. Continuous stress relaxation measurements indicate that these rubbers obey approximately the…

Viscometric Investigation of Dimethylsiloxane Polymers

Arthur J. Barry1946-12-01Journal of Applied Physics

The intrinsic viscosities of an extended series of linear methyl polysiloxane fluids, having dimethylsiloxane (Me2SiO) as the repeating unit, have been determined in toluene solution. These values have been correlated with their molecular weights, determined chemically and by osmotic pressure and light scattering meas…
