  • Radiation from transmission lines

    Publication Year: 1923, Page(s):95 - 105

    The aim of this investigation was to contribute something to our knowledge of traveling electromagnetic waves. Among the transient phenomena that occur along transmission lines, these are still little known, especially as far as their “attenuation” and “distortion,” or change in shape near the “wave front” are concerned. It is first seen that the “c... View full abstract»

    The Department of Chemical Engineering of the Carnegie Institute of Technology has been conducting a series of tests to determine the relative merits of various oils as usable fuels. The completion of this important work should go a long way toward solving the problem of oil conservation, by the possible development of a new fuel. View full abstract»

    THE oscillograph has emerged from the obscurity of scientific laboratories and from the test departments of great electrical industries so that today it is occasionally seen on a rapidly accelerating elevated train, in a soaring air-plane, in a destroyer dashing through a rough sea, on the polished top of a conference table, and, in each case, operating as perfectly as though it were in a well-equ...

    IT is well known that a symmetrical T-connection of three simple impedances a o, o b, and o q, Fig. 1, in which the two arms a o, and b o are electrically equal, and with their common terminal o connected to the ground or return conductor g h through the impedance o q, can be completely replaced, at any single assigned alternating-current frequency, by a certain symmetrical �...

    THE point is well known and generally accepted that many things can be done which do not become general practise until the economics governing the practise show that the difference between “cost of doing” and “earnings through doing” is on the proper side of the balance sheet.

  • The “Heavisidion” a computing kinematic device for long transmission lines

    Publication Year: 1923, Page(s):127 - 138

    Subject of the Paper. — A kinematic computing device is described which can be set to represent vectorially the voltage and the current at any point of a long transmission line with uniformly distributed properties and with a given load. The device has been named after Oliver Heaviside who was among the first to establish and to solve the fundamental differential equations of such a line. T... View full abstract»

  • Electromagnetic forces; A search for more rational fundamentals; A proposed revision of the laws

    Publication Year: 1923, Page(s):139 - 154
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3951 KB)

    Reasons are given why it is desirable to revise some of our older laws regarding electromagnetic forces and motions which are the basis of all electromotive devices, in order to conform better to more modern developments. Researches with high-current densities in such mobile conductors as liquids and arcs, have brought out some heretofore unnoticed forces, the existence of some of which had been d...

  • Physical interpretation of complex angles and their functions

    Publication Year: 1923, Page(s):155 - 164
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2129 KB)

    A child's idea of an angle is a corner or edge; the sharper the corner or edge, the smaller is the angle, and hence expressions like “acute (sharp) angle,” “obtu e (blunt) angle,” etc. With a little schooling his idea of an angle is broadened into that of turning or rotation and finds a geometrical expression in a circle. The amount of turning is represented by the area... View full abstract»

    AFTER reading with considerable interest, the two papers presented at the annual convention of the Institute, dealing with the dielectric strength of cables1, the writer analyzed the data presented in each paper from an entirely different viewpoint and also the data given in each paper according to the views of the other paper.

  • Applications and limitations of thermocouples for measuring temperatures

    Publication Year: 1923, Page(s):171 - 178
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1808 KB)

    THE increasing application of temperature measurements to central station control arises primarily from the fact that the limiting factor of safe operation is temperature rather than current or energy output. Another and closely related factor is that of efficiency. With these two influences bearing upon the management there is demanded a knowledge of temperature conditions in the boiler, the engi...

    The Report of the Street Lighting Committee of the American Society for Municipal Improvements is of unusual interest in view of the fact this society is composed of mayors, city councilmen, city engineers and others interested in civic affairs whose opinions on street lighting matters are a considerable factor in shaping the trend of street lighting practise.

  • Lighting of the food industries

    Although our food industries are highly developed from the standpoint of modern manufacturing methods and sanitary standards, artificial illumination, generally speaking, is an element which has suffered serious neglect. The benefits of good lighting and their relative order of importance in the food industry are, briefly, improved sanitation, increased safety, greater production, reduced spoilage...

    A comparative study of the methods which are used in measuring dielectric loss in condensers, especially those having a large value of capacitance is being made by the Bureau of Standards, which has an air condenser with a capacitance of 1/10 of a microfarad which will withstand 3000 volts without any appearance of corona. The losses in other condensers may be compared with this air condenser whic... View full abstract»
