The new conditions of life brought about by the material advances of recent times, which have been achieved primarily as a result of the work of scientists and engineers, have brought with them new and pressing problems??social, economic, political, and international. In this address,* Doctor Durand states that we (engineers) cannot evade the responsibility which rests upon us to take our due sh... View full abstract»

Publication Year: 1936, Page(s):1314 - 1318
| | PDF (1652 KB)

Cathode-ray oscillographs, a few years ago found only in research laboratories, have become extremely useful tools in the hands of operating engineers, research technicians, and teachers alike; however the usefulness of cathode-ray oscillographs of the ordinary portable type is limited almost entirely to the observation of sustained periodic phenomena, and is of little use in the study of transien...

| | PDF (2170 KB)

Formulas for practical use in the calculation of the resistances from grounding conductors of variou forms to the earth are given in this paper and their use illustrated by examples. The accuracy of the formulas varies considerably, as discussed in the paper, but is sufficiently good that the methods should be helpful to those whose work involves problems of grounding.

• ### A-C Characteristics of Dielectrics-II

Publication Year: 1936, Page(s):1329 - 1337
| | PDF (1925 KB)

Predetermination of the a-c characteristics of dielectrics by d-c measurements was discussed in an earlier paper.1 The present paper further shows that the method of 3 exponentials, although predicting accurately the in-phase component of current caused by reversible absorption, usually yields results of less than the true value in predicting the quadrature component. Charts are present... View full abstract»

• ### Currents and Potentials Along Leaky Ground-Return Conductors

Publication Year: 1936, Page(s):1338 - 1346

| | PDF (1577 KB)

Current propagation and earth potentials for earth-return conductors with application to electric railway systems are discussed in this paper. General formulas are derived from which solutions may be obtained for problemes such as propagation of track currents and voltages, and earth potentials imposed on neighboring conductors.

| | PDF (4109 KB)

A new transient calorimetric method for measurement of dielectric losses in solids at 10,000 volts and 1,000 kilocycles, is described in this paper and experimental data obtained by this method are presented. A steady-state method also is described and a direct comparison between the results obtained by the 2 methods is given. The absolute value of loss factor (0.0009) determined for quartz shows ...

To provide additional bridges between the fields of mathematics and electrical engineering is the main object of this paper, which is a sequel to a previous work on dyadic algebra. The paper includes an application of Gibbs's directional ellipse to 3-phase circuits, a treatment of symmetrical components by using the isoclinic unit vector and 2 circular complex vectors and an exposition of dyadics ...

• ### Amplification Loci of Resistance-Capacitance Coupled Amplifiers

Publication Year: 1936, Page(s):1364 - 1371

| | PDF (1415 KB)

This paper applies the method of circular loci to the determination of the vector amplifcation of resistance-capacitance coupled amplifiers. It is shown that the locus for both exact and approximate equivalent circuits is the sum of 2 circles, whereas for the approximate circuits at high or low frequency the locus is a single circle. The locus of vector amplification for this type of amplifier may... View full abstract»

In this paper the use of resistance-welding timers using igniter-type mercury-cathode tubes is reviewed briefly and a seam-welding control unit containing a new design of inductive timer is described, An ignition delay'' form of control of welding heat or current magnitude is presented in which one set of power tubes controls both current magnitude and time duration. Comparison is made with the ... View full abstract»

• ### Negative-Sequence Reactance of Synchronous Machines

| | PDF (1565 KB)

A theoretical analysis of the method proposed by the AIEE committee on electrical machinery for measuring the negative-sequence reactance of synchronous machines is presented in this paper. The analysis proves that the method leads to a correct measurement of the negative-sequence reactance for the operating condition most frequently met in applying the method of symmetrical components, but that t...
