STUDY OF SODIUM VAPOR EJECTED INTO THE UPPER ATMOSPHERE
Two Aerobee rockets were employed to eject relatively large amounts of sodium vapor into the earth's atmosphere. One of the flights occurred during evening twilight and sodium was placed in the sunlit atmosphere from 75 to 110 km. Sodium D-line emission (λ 5890 A) was observed in the ejected trail above 90 km, and 589…

Foam stability: Part. II. Gas diffusion in foams
Abstract Pressure differences between foam bubbles of unequal size are the cause of gas transfer from small to larger bubbles. The rate at which the small bubbles decrease in size is calculated as a function of the radius of the bubbles, the surface tension of the liquid and the thickness and permeability of the liqui…

Phase Equilibria in the System ZnO-P[sub 2] O[sub 5]
Phase relationships in the system were determined in air in the range between and , using solid state and quenching methods. Three congruently melting compounds exist, , , and . The orthophosphate has a sluggish, reversible inversion at 942° and melts at 1060°±8°C. The pyrophosphate undergoes a rapid, reversible inver…
Intrinsic viscosities of cellulose derivatives
Abstract Intrinsic viscosities of cellulose acetates of degrees of substitution 2.86 and 3.00 and of cellulose trinitrate have been investigated as functions of temperature, solvent, and molecular weight. Large negative temperature coefficients ( ca. −0.6% per degree) of [η] appear to be characteristic of cellulosic c…

Preliminary Note on the Solubility of Oxygen in alpha-Zirconium.
An investigation was started on the solid solubility range of oxygen in alpha -zirconium. The solubility limit for samples heat-treated at 8O0 C was found to be about ZrO/sub 0.40. After annealing at 800 C, the sample ZrO/sub 0.30 gives x-ray powder photographs which show the oxygen atoms to be distributed at random i…
The control of flux waveforms in iron testing by the application of feedback amplifier techniques
By the use of a feedback amplifier technique, the voltage appearing across a search coil wound on a ferromagnetic core can be made to follow any desired driving waveform, and the inherent harmonic distortion effects arising from non-linear B/H characteristics are reduced by an amount approximating to the loop gain. Th…
The digital computer applied to the design of large power transformers
The paper describes an extensive investigation into the design of transformers with the aid of a high-speed digital computer. A general programme has been developed covering a range of transformers from 30 to 210 MVA, and has been tested for a wide range of designs within these limits. The subdivision of the process o…
Study of Collisions. Part. I. A Survey of the Periodical Literature
A review of the periodical literature on the subject of impact and the coefficient of restitution ε shows that it depends not only on the materials (elastic moduli) of the colliding objects, but also on (1) their relative normal velocity at the instant of impact, (2) their shapes and sizes, (3) their masses, and (4) t…
Crystallinity and orientation in silicone rubber. II. Physical measurements
Abstract Density data for a silica‐filled dimethylpolysiloxane rubber define incipient crystallization conditions and indicate the forms of crystalline growth for the unstressed rubber and for a sample at 200% elongation. Temperature—tension data for the same silicafilled rubber show incipient crystallinity temperatur…
Chemical Factors Affecting Stress Corrosion Cracking of 18–8 Stainless Steels
Transgranular stress corrosion cracking of 18–8 Type 304 specimens in boiling 42% does not depend on rate of stressing (<1 sec to 10 min) nor on small variations in degree of plastic deformation. Cold worked specimens fail in shorter times than annealed, sheared specimens. Addition of to decreases cracking time wherea…
Mechanics of Elastic Performance of Textile Materials
This paper is the first of a series which will deal with torque in textile systems. It is concerned principally with the analysis of torque developed in twisted singles yarns as created by (a) fiber bending, ( b ) fiber torsion, and (c) bending and torsion in com bination. Equations are developed, using elastic theory…

Foam stability: Part V. Mechanism of film rupture
Abstract Lamellae of pure liquid and low‐molecular solutions are unstable because of the absence of a limiting thickness. Rapid collapse of these lamellae may start at relatively large thickness (∼ 500 Å) under influence of the London‐van der Waals attractive forces. Small quantities of surface active ions will preven…
