The rigidity of rubber, considered as a network of flexible molecules with Gaussian configuration functions, can be calculated for a particular sample if one is given a complete description of the molecular network or certain types of statistical description. In particular, it is sufficient to know the distribution of…
A bstract The fundamental condition for glass formation is the existence of strongly bonded large networks or long chains of atoms in the liquid. Such chains or networks prevent or hinder the orderly orientation of atoms in the chains or networks themselves and also that of atoms, not in the networks in the liquid, ne…
A detailed discussion of the energy loss of negative mesotrons in matter is presented. The energy range considered is from +2000 ev to the lowest quantized orbit of the mesotron. The most important mechanism for energy loss is that of electron collisions except very near the nucleus, where radiation losses are importa…
A furnace is described for use with the electron diffraction camera for the study of chemical and physical reactions occurring on surfaces up to 1000°C. The specimens are mounted in the body of a 25 Cr-12 Ni alloy block which is surrounded by a series of radiation shields. The metal block is heated internally by a tun…
Abstract A description is given of the preparation, birefringence, and swelling capacity of a series of microscopically homogeneous, partially acetylated cellulose model filaments with an acetyl content varying from 0 to 2.3 acetyl groups per glucose residue, and obtained either by acetylation or by deacetylation. A h…

A “Boudin” is a sausage, and boudinage is a sausage structure. The term was coined by Lohest [see “References” at end of paper, 1909] for a peculiar structure in certain sandstone beds in the Bastogne in Belgium. The sandstone beds are segmented and the segments are separated from each other by quartz veins. Each part…

A bstract Assuming from a consideration of silicate minerals that aluminum should replace silicon in silicates, the authors investigated the system Na 2 O‐CaO‐SiO 2 ‐Al 2 O 3 . Densities and refractive indices have been determined and molecular refractions have been calculated. Partial molecular refractivities of Al 2…

An analysis has been made of the factors involved in the A.S.T.M. Trapezoid Tear-Strength Test. The tear strength of a fabric measured by this test is dependent mainly on the extensibility of the threads, the breaking strength of the threads, the effective specimen length, and the number of threads per inch of fabric.…

When sound of high amplitude is transmitted into a liquid by means of a mechanical driving device, the ultimate limitation to the power that can be transferred is cavitation or breakdown of the liquid under high internal stresses. A study of cavitation has resulted in establishing the following results. Under steady-s…
Biotite micas from igneous rocks differ from one another mainly in their contents of SiO <sub>2</sub> , Al <sub>2</sub> O <sub>3</sub> , MgO, total Fe as FeO and, to a less extent, in TiO <sub>2</sub> . The variation in amount of each of these oxides was investigated. It was found that some depend on the nature of min…
