Abstract “Exposure-cracking” is the fissuring which occurs when stretched rubber is placed in an atmosphere containing ozone, and is frequently wrongly described as “sun-cracking”. These cracks form in the rubber at right angles to the applied stress and must be distinguished from crazing, the fissures of which occur…
In this paper the spring-dashpot theory which has been applied in previous papers in this series to single fibers and to yarns is applied here to the experimental investi gations of a plush fabric which have been published by Fox and Schwarz. This serves to outline the experimental methods which should be followed if…
Abstract For small loadings (up to about 10 per cent volume parts) colloidal carbon-black spheres may be considered as suspended in a continuous rubber matrix. In the present paper this model is generalized for ellipsoidal (including plate-like and rodlike) filler particles, and it is extended to the computation of va…
A general theory of strain and stress compatibility in yielded metals is evolved from well-known experimental results and the Energy of Deformation Theory of Yield due to Huber, von Mises, and more recently Hencky.

The oxides of cerium, yttrium, silicon, magnesium, and calcium were added in various proportions to zirconia of 99-percent purity, and the effects of these additions, combined with preheating at various temperatures ranging from 1,450 to 1,950 C, on thermal length changes of the zirconia during heating and cooling bet…
The theory of volume effect in photoelectric emission is developed. Formulae are derived for the rate of electron excitation and for the photoelectric yield. The calculated threshold frequencies for volume effect are 5.91\ifmmode\times\else\texttimes\fi{}${10}^{14}$ and 5.69\ifmmode\times\else\texttimes\fi{}${10}^{14}…
Abstract 1. Analysis shows that, subject to certain limitations, the modulus of a loaded stock (M * ) depends on the modulus of the rubber matrix ( M ), according to the equation: M * =M(1+2.5ϕ) where 100ϕ is the volume percentage of filler. When these limitations are fulfilled, the effect of compounding on modulus is…
Discussion and author's closure of paper 45–49 by J. S. Askey and J. S. Johnson, presented at the AIEE winter technical meeting, New York, N. Y., January 22–26, 1945, and published in AIEE TRANSACTIONS, 1945, June section, pages 347–51.
The instantaneous distribution of chain compositions and chain lengths in vinyl copolymers is obtained in a simple form valid for long chains. The compositions of chains of a given length are normally distributed about the mean value, with a standard deviation which can be calculated from experimentally observable qua…

Closed analytical expressions are obtained for the shapes of the modified Compton lines scattered from the elements H to Ne, in atomic form. The widths of the Compton lines are calculated for these atoms, and conditions of resolution from the unmodified lines are obtained. Certain errors in other work on this subject…

A bstract Equilibrium In the system has been investigated for compositions from 0.6 to 75 weight per cent MgO. Three intermediate compounds are present. MgO⋅B 2 O 3 melts incongruently at 988°C. to form 2MgO⋅B 2 O 3 and a liquid containing more than 99% B 2 O 3 . The other two compounds melt congruently: 2MgO⋅B 2 O 3…
Results are given of seven melting-point determinations on alpha-alumina of high purity in an oxidizing atmosphere and under atmospheric pressure. There was detectable contamination of the specimens by vapors of other elements in the furnace atmosphere, but the results are believed to show that the melting point of al…
