In the control and protective circuits of complex electrical systems it is frequently necessary to make intricate interconnections of relay contacts and switches. Examples of these circuits occur in automatic telephone exchanges, industrial motor-control...

The energy of the first excited levels of benzene is calculated by the method of antisymmetrized molecular orbitals. The results predict two weak bands, due to forbidden electronic transitions, at λ = 2500 and λ = 2100 and a strong band at λ = 1500....

The formation of tactoids from thixotropic sols, of Schiller layers from iron‐oxide sols, the separation of tobacco virus solutions and bentonite sols into two liquid layers and the crystallization of proteins are regarded as examples of unipolar coacervation...

The theory of the influence of substituents on dissociation constants presented in an earlier article of the same title is extended to acids ellipsoidal in shape. Bjerrum's formula is obtained in the limiting case of unit eccentricity of the elliptical...

Since the majority of molecules of chemical interest are too heavy to permit resolution of the rotational structure of the infra‐red bands, it is of interest to find what information can be derived from a study of the band envelopes. Considerations...

Murnaghan's theory of finite deformations is applied to a discussion of the effect of hydrostaticpressure upon the elastic coefficients of an isotropic body, for small strains superposed on the hydrostatic strain. Stress‐strain equations for the small...

X‐ray diffraction patterns of water were obtained at five temperatures: 1.5°, 13°, 30°, 62°, and 83°C. The radiation was CuKα and MoKα, monochromated by reflection from a rocksalt crystal. Radial distribution curves for water at the five temperatures...

The free volume is defined as the total integral over that part of the potential energy of the molecule in the liquid which is due to thermal displacements of the center of gravity of the molecule from its equilibrium position. The free angle is the corresponding...

The cat was used as a representative quadruped for a study of the action of the locomotor apparatus in walking. In the analysis the body was considered as being made up of eleven parts behaving in such a fashion that they could be considered as rigid...

A crystal which has absorbed a light quantum can be treated either as an assembly of molecules or else as a giant molecule. If the exchange of excitation energy between crystal cells is slow as compared to the periods of vibration, the first description...

A theory of order and disorder in solid solutions, based upon a direct evaluation of the crystalline partition function, is described. As in the theory of Bethe, the fluctuation in energy within states of a fixed degree of order, is taken into account....

A theoretical study of the transmission of electromagnetic waves in hollow conducting pipes of elliptic cross section, including field configurations, critical frequencies, velocities of propagation, and attenuations for the six lowest order waves. The...
A study has been made of the fractionation of the lithiumisotopes by electrolysis and of the lithium,potassium, and nitrogen isotopes by chemical exchange with zeolites. The fractionation factor obtained by a ``batch'' electrolysis of lithium chloride...
The heat capacity of nitrogen tetroxide has been measured from 15°K to the boiling point, 294.25°K. The melting point is 261.90°K. The heats of fusion and vaporization were found to be 3502 and 9110 cal./mole, respectively. The vapor pressures of solid...

The investigations reported here on azomethane, CH3·N=N·CH3, N–N′ dimethylhydrazine, (CH3)HN·NH(CH3), and acetaldazine (CH3)HC=N–N=CH(CH3) were carried out primarily to obtain information on the general form and some of the structural properties...
Electron diffraction studies have been made upon layers of molecules of barium stearate and of stearic acid built upon surfaces by the Langmuir‐Blodgett method. Upon clean metal surfaces odd numbers of layers have been built, and investigated by the...
In previous papers, the energy of H3 and of H3 + has been obtained by the variational method for linear configurations. In this treatment we are able to evaluate the difficult three center integrals for nonlinear configurations with the aid of the differential...
The Arnold-Chiari malformation is a downward elongation of the cerebellum and brain stem into the cervical portion of the spinal canal associated with spina bifida. Russell and Donald 1 pointed out that it is a more frequent accompaniment of spina bifida...

THERE has long been a need for a means of evaluating the performance of induction motors under transient conditions, as when driving pulsating compressor loads. The familiar equivalent-circuit analysis is inadequate to determine the effects of pulsating...
