Charles Proteus Steinmetz: This paper deals with the wave-shape distortion produced in alternating-current circuits by the introduction of iron. It is a theoretical paper, and while of scientific interest appears at first of rather little-practical value to the electrical engineer. There is, however, to-day only a very short step between pure scientific investigation and engineering practice; and I hope to ...

A new analysis method was developed to simulate the dynamic process of a frictional heatstress coupled field. The relationship between the frictional heat and the thermal stress was investigated for concave cylinder contact conditions. The results show that, as a nonlinear contact problem, the frictional heat at the contact areas changes with moving velocity in both value and distribution, and ...

The refraction-diffraction of surface waves due to porous variable depth has been the subject of many investigations. In the present study, we extend the boundary-value problem of impermeable varying topography to that of a variable depth porous seabed, which is the situation most likely to be encountered in practical problems of coastal engineering. A wave-induced fluid motion is applied to ...
Charles Proteus Steinmetz: This paper deals with the wave-shape distortion produced in alternating-current circuits by the introduction of iron. It is a theoretical paper, and while of scientific interest appears at first of rather little-practical value to the electrical engineer. There is, however, to-day only a very short step between pure scientific investigation and engineering practice; and I hope to show you that the phenomena dealt with in this paper, and similar phenomena, are of very great practical importance in alternating- current distribution; that is, wave-shape distortion may lead to effects not only very marked and pronounced but occasionally disastrous. In general, in investigating the effect of iron in alternating-current circuits, the curve of exciting current is calculated from the hysteresis cycle of the iron. Dr. Bedell proceeds inversely by superposing different harmonics of current. From these complex currents he produces a hysteresis loop, noting whether this hysteresis loop is a reasonable one or not, and deriving therefrom relations regarding the relative intensity and phase of the triple harmonic in the wave of exciting current. As far as the investigation goes, it extends only to the fundamental and triple harmonics; the investigation of higher harmonics is left to a future occasion.
A new analysis method was developed to simulate the dynamic process of a frictional heatstress coupled field. The relationship between the frictional heat and the thermal stress was investigated for concave cylinder contact conditions. The results show that, as a nonlinear contact problem, the frictional heat at the contact areas changes with moving velocity in both value and distribution, and that the transient frictional heat at the dynamic condition has a peak within a cycle. The dynamic process of friction heat and thermal stresses affects diffusion of the frictional effects. The result can be helpful for dynamic simulation of diffusion lubrication of elements at elevated temperatures.
The refraction-diffraction of surface waves due to porous variable depth has been the subject of many investigations. In the present study, we extend the boundary-value problem of impermeable varying topography to that of a variable depth porous seabed, which is the situation most likely to be encountered in practical problems of coastal engineering. A wave-induced fluid motion is applied to the porous bottom, while the well-known linear potential theory is applied to the free-water above the bottom. Eigenfunction expansions are employed to derive the matching condition and the so-called modified dispersion relation. As a result of the porous bottom, the wavenumber becomes a complex value, of which the real part represents the spatial periodicity while the imaginary part refers to the energy dissipation. The characteristics of water waves over a porous bottom are studied in detail. By neglecting the non-propagating modes which only have a local effect and damp exponentially with distance, we derive a mathematical model to represent the characteristics of both the wave refraction-diffraction and wave-damping. The developed model is applied to the damping problem of waves over submerged porous breakwaters.
W. B. Brady: Referring to the paper by Messrs. Edgecomb and Dick, the brush manufacturers are very much interested in the subject of brush losses and we are very glad the Institute has taken up this matter. We have been working on the development of brush tests for more than six years but we have been handicapped by the lack of apparatus that would give us consistent results. Then, again, as we have developed our own apparatus the results we got w Te applicable to that apparatus and only under the exact conditions of that test. This is due to the number of variables and losses that are in a certain combination under the conditions of that test. By having these losses more definitely separated and understood we may be able to get a definite basis to make our results comparable. One of the best ways I know of is to standardize the brush testing apparatus and I hope this can be done in the very near future. It will be a decided step in brush development which will be of great assistance to engineers.
Although the coefficient of restitution was originally thought to be only a material property, the coefficient of restitution also depends upon initial conditions as well as on the frictional effect for oblique collisions. The objective of this paper is to demonstrate a method for obtaining the coefficient of restitution for oblique collisions and thereby to provide a theoretical guide for collision experiments. In this paper, we derive expressions for the energetic coefficient of restitution (e∗) based on general normal contact deformation law, by which the value of e∗can be obtained according to the initial conditions. An example shows that the results calculated by the derived expressions are reasonable.
The most serious problem encountered in the application of electric drive to large mine hoists is that of electrical control. It is necessary, in order to secure continued successful operation of an electric hoist, to furnish a control system which is absolutely reliable at all times. The design must be such that all parts of the apparatus will withstand the most severe, and even unreasonable, conditions of service without giving trouble and without repeated attention and repairs. It should be so designed that it is impossible for the operator to damage the controller or any part of the machinery by a wrong movement of the operating handle or by misjudgment of conditions.
Motors have been used in paper mills for the last twenty years and have been applied with success to every machine used in the process of making paper. By means of motors it has been possible to study the power requirements of various machines and much useful information has been obtained for the manufacturer of the paper, of the machine, and of the motor. As far as the writer knows, very little of this information has been published and it is the intention of this paper to set forth facts that have been observed and state the possible laws that may be deduced from these facts. This paper is confined to the finishing department of the paper mill and more particularly to the motor drives for three types of paper calenders.
The function of a fly-wheel in a system with a rapidly fluctuating load is to equalize the power requirements, thus reducing the sudden shocks to the moving parts and thereby the strains on the machine frame and both the mechanical and electrical strains on the driving motor. For the fly-wheel to be effective the speed characteristic of the motor should be such that the motor will slow down as the load increases and will increase in speed as the load decreases. In the case of large shears the full working load is applied suddenly and the fly wheel is called upon to deliver energy through a very short space of time, varying from one-half a second to two seconds, according to the size of the machine and the size and condition of the material cut. Thus it is evident that the speed characteristics of the driving motor must be inherent, as the time is too short to depend upon a practical control means for changing the motor characteristics.
