Certain developments in the field of built-up bonded mica products for use as electrical insulation are described with emphasis placed on high-temperature applications.
The rate of dehydration of copper sulphate pentahydrate has been determined over a range of low pressures of water vapor. It has been found that as the pressures are increased, the rate at first drops very rapidly; this drop is followed by a period of marked acceleration, which is followed in turn by a gradual decline…
Abstract Clay mineral studies of recent sediments from a diversity of environments in the vicinity of Rockport, Texas, have been made as part of American Petroleum Institute Project 51. The bulk of the argillaceous material in these sediments is a complex mixture of poorly crystallized three-layer clay minerals. Probl…
Single crystals of a number of iron-nickel alloys were prepared, and measurements made of the magnetic crystal anisotropy, and of the magnetostriction at saturation in different crystallographic directions, as dependent on the rate of cooling of the specimens after annealing. There is a large effect of the cooling rat…

The densities of liquids in the systems Li 2 O–B 2 O 3 , Na 2 O–B 2 O 3 , and K 2 O–B 2 O 3 were measured by a counterbalanced‐sphere method over the approximate temperature range 600° to 1000°C. The room‐temperature densities of alkali borate glasses were also measured. Density increased with increasing percentages o…

In connection with Galt and Herring's observation on thin whiskers of tin, the properties of a screw dislocation in a cylinder are worked out. When all boundary conditions are taken into account, the image force tends to keep the dislocation along the axis. Only when it is displaced about half-way to the surface does…
Abstract The solubility of a polymer in a non‐polymeric liquid depends mainly on the heat of mixing. When no polar forces are concerned, the cohesive energy densities of polymer and solvent must be close; a method is given for estimating the cohesive energy densities of polymers from a set of additive constants, and i…
The influence of controlled porosity on the compression strength of sintered pure alumina and of partly magnesia‐stabilized zirconia was investigated. Bodies with porosities ranging from approximately 3 to 60% by volume were prepared utilizing hydrogen peroxide to induce pore formation. Cubes of approximately 1.2‐cm,…
As there are different points of view concerning the molecular dynamical states in solid methane, especially concerning the $\ensuremath{\lambda}$-transition at 20.42\ifmmode^\circ\else\textdegree\fi{}K, we have investigated the manner in which the new method of nuclear magnetic resonance throws light on the problem.…
