Abstract Stress-strain data are given for two types of vulcanized rubber: (1) an 8% S rubber, and (2) a latex rubber. The types of deformation studied were simple elongation, 2-dimensional extension (or compression), pure shear, and combined elongation and shear. Comparison with the theoretical relations based on the…

Two mechanical properties of rubber-like materials relevant to the design of anti-vibration devices are the dynamic elastic compression modulus and the associated resilience. A method is described for the evaluation of these properties over the temperature range 5° to 40° C. Results are given for natural rubber, for t…
A bstract The volume expansion of cristobalite, as it passes through the low‐temperature inversion range, was studied by means of a dilatometer in which the cristobalite expanded against a column of mercury. The volume change was measured in a capillary tube attached to the mercury column. The temperature of inversion…
A bstract Physical and chemical properties are discussed for Vycor‐brand 96% silica glasses prepared from glasses of lower silica content by a leaching process, and a brief résumé of this process is given. The intermediate porous glass and a translucent or white opaque form of the final 96% silica glass made by the Mu…
The effect of the filler upon the modulus of compounded rubber has been calculated with the aid of some simplifying assumptions. From these calculations it is found that the increase in modulus, caused by the filler, is directly proportional to the volume loading, and is independent of the particle size of the filler.…
A high vacuum, curved-crystal spectrograph was constructed for study of the $K$-absorption edge and the accompanying secondary absorption structures for evaporated films of sodium metal and of the sodium halides. Comparison of the $K{\ensuremath{\beta}}_{x}$ emission line and the $K$-absorption edge for metallic sodiu…

Elongation of swollen vulcanized rubber, or other polymeric materials possessing random network structures, should increase the amount of liquid absorbed (dissolved) at equilibrium with an excess of the swelling agent. According to a previously published equation relating to the thermodynamics of stretching and swelli…
Vapor pressures of crystalline KCl, KBr, KI, and NaCl have been measured in the pressure range of 10−1 to 10−7 mm by a surface ionization method. Heats and entropies of vaporization are calculated from the data. The heats of vaporization at 0°K and entropies at 298°K are also calculated. From the data, saturated KCl v…

Abstract 1. The complete decay of stress in the rubbers studied, held at constant elongation, appeared to involve the rupturing of a definite bond, either at some point along the molecular chain or at the cross-linking bond put in by vulcanization. In the case of a Hevea rubber gum stock the data could be fitted very…
Abstract The problem of the thermodynamics of crystal lattices has been treated by rigorous methods recently in a series of papers by Born and collaborators. In particular, Bradburn succeeded in deriving the equation of state for a solid cubic crystal, consisting of identical atoms, under the assumption that the mutua…
Abstract The causes and types of continuous spectra emitted by flames are discussed and their importance stressed. It is shown that the yellow-green continuous spectrum emitted by some flames containing oxides of nitrogen is probably identical with the spectrum of the air after glow and is therefore due to a reaction…
