The magnetization curves for the [100], [110] and [111] directions of single crytals of iron containing 3.85 percent silicon were obtained from single crystal specimens cut in the form of hollow parallelograms so that the sides of each specimen were parallel to the tetragonal, digonal or trigonal axes, respectively. T…

Abstract Es werden die chemischen und metallurgischen Bedingungen näher beschrieben, die für die Reduktion des Ti oder Zr aus ihren Halogen‐ oder Sauerstoffverbindungen berücksichtigt werden müssen. Ein Apparat zur Reduktion größerer Mengen des Oxydes rnit Ca wird beschrieben. Das so gewonnene Metal1 ist warm verformb…
Abstract Durch Röntgenuntersuchung der Systeme CaAl 2 O 3 und SrOAl 2 O 3 konnte festgestellt werden, daß in jenem System 5 und diesem 4 intermediäre Kristallarten auftreten. Da jedes Strontiumaluminat in einem Calciumaluminat ein Gegenstück hat, sind die Systeme einander weitgehend analog.
A dew point apparatus was devised for measuring the humidity over aqueous solutions of non-volatile substances. Preliminary experiments proved that results obtained with the instrument were reproducible and that it could be used to make dependable measurements of the relative humidity over such solutions in the range…
The X-ray method has been employed to investigate the occlusion of hydrogen by palladium when the pressure of the hydrogen surrounding the palladium and the temperature of the palladium are varied. Measurements were made of the parameter of palladium at temperatures of 80, 100, 120, 140 and 160° C. when the palladium…

Heat-Qf-solution and ignition-loss methods have been developed for determining the degree of hydration of magnesia in hydrated dolomitic limes and in hydrated dolomitic lime putties. The rate of hydratiQn Qf magnesia in such limes has been studied when the limes were aged as putties at different temperatures, when sub…
Molecular structures of P4O6 and As4O6 were determined from electron diffraction data. P4O6 was found to have the symmetry of the point group Td with an angle P–O–P of 128.5±1.5°, and a P–O distance of 1.67±0.03A. In this structure the phosphorus oxygen distances and the phosphorus valence angles were preserved with r…
The current density in a focused beam of cathode rays is shown to have an upper limit defined by I = I0(Ee/kT+1) sin2φ, where I is the maximum current density obtainable in the focused spot, I0is the current density at the cathode, E is the voltage at the focus relative to the cathode, T is the absolute temperature of…

An attempt was made in a previously reported research (14) to determine the volumetric contraction occurring in the water adsorbed by cellulosic materials. Apparent density measurements of wood and cellulose containing various amounts of adsorbed water were made in benzene. Benzene causes no swelling of cellulosic mat…
The mathematical treatment of dipole-dipole coupling in my previous article on magnetism applies with but little modification to the electric case. Because of fluctuation effects, the use of the usual Lorentz local field E+4πP/3 and of the Clausius-Mossotti formula cannot be justified except as a first approximation v…
