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…
In order to elucidate further the concept of relaxation of shear stress across grain boundaries in metals, the temperature dependence of internal friction and rigidity modulus of 99.991 percent aluminum have been measured as a function of frequency of torsional vibration and as a function of grain size of the specimen…
Abstract The system aluminium-manganese-zinc has been examined in the range 0 to 95 % of zinc, and 0 to 3 % of manganese. Attention was directed only to the constitution of the alloys above the solidus. Using micrographic and X-ray methods, and the chemical analysis of crystals separated from slowly cooled alloys, it…
Abstract The effect on X-ray reflexion of deviations of the atoms from the ideal lattice sites caused by the presence of randomly distributed foreign atoms in a dilute solid solution is investigated quantitatively. The form of the function used to describe these deviations is suggested by the distortions produced in a…
The dielectric constant and loss of barium titanate and barium-strontium titanate have been measured at biasing field strengths from 0 to 5 megavolts per meter, at temperatures from -50\ifmmode^\circ\else\textdegree\fi{}C to +135\ifmmode^\circ\else\textdegree\fi{}C and at frequencies from 0.1 to 25 megacycles.
