    The subject of procedure and policy in the formulation of industrial electrical standards was brought to the attention of the Winter Convention in a forceful address of President Chesney, which is printed elsewhere in this issue of the JOURNAL. Briefly stated, the question at issue is whether the Institute should continue as in the past 28 years to be the final authority on electrical standards in... View full abstract»

    A new rectifier utilizing a partially oxidized disk of copper as a rectifier unit is described. The disks may be arranged into groups suitable for all fields of rectifier applications. The rectification appears to take place at the junction between the copper and the oxide without observable physical or chemical changes, and is similar in character to rectification by the hot-cathode type of recti...

    About fifty American engineering colleges are carrying on organized engineering research. Fifteen of these received during the year 1924–25 more than $500,000 for research through cooperative relations with industry. The total annual expenditure by engineering colleges for research is more than $1,000,000. The cooperative relations between Purdue University and the American Railway Associat...

  • Voltage standardization: Its relation to the interconnected power companies of the Southeast

    Publication Year: 1927, Page(s):223 - 230
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1894 KB)

    Voltage standardization has long been recognized as desirable, and to date no definite standards have been accepted and applied. An attempt is now being made to coordinate the recommendations of the different power companies and manufacturers with a view towards adopting definite voltage standards for all apparatus. A proposal has recently been submitted by the manufacturers which is not applicabl... View full abstract»

  • Measurement of telegraph transmission

    Publication Year: 1927, Page(s):231 - 240
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2927 KB)

    Various factors contribute to impair the quality of telegraph signals. For instance, there may be interfering currents either induced in the circuit or brought in by conduction, the proportioning of the circuit elements may be imperfect or batteries and relays may be out of adjustment. The result in any case is to distort the telegraph signals so that the received signals are not a true copy of th... View full abstract»

  • Computation of the unbalance factor of a three-phase triangle when lengths of three sides are given

    Publication Year: 1927, Page(s):240 - 241
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (434 KB)

    In an important paper read before the June 1918 Convention of the A. I. E. E., it was shown by Mr. C. L. Fortescue, that any dissymmetrical system of three-phase voltages or currents could be resolved, by vector methods, into a pair of symmetrical systems, one forward and the other backward. The numerical ratio of the latter to the former is called the unbalance factor of the system. Although seve... View full abstract»

  • Standardization of voltage ratings for power systems and equipment

    Publication Year: 1927, Page(s):242 - 251

    This paper undertakes to analyze the voltage practises and requirements of alternating current power systems with the aim of arriving at voltage standards that adequately correct and extend present standards. Utilization, or receiving terminals, is taken as the point of reference and for designation of system, circuit and equipment voltages. For this analysis and development of voltage standards a...

    Much interest has been manifested during recent years in the use of the corona discharge during the cracking of petroleum to increase the production of gasoline, and the results of studies on this subject are given in Bureau of Mines Technical Paper, 375, by J. J. Jakosky. View full abstract»

  • A new 132,000-volt cable joint

    Publication Year: 1927, Page(s):252 - 257
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2057 KB)

    This paper describes what is believed to be a new form of high-voltage joint. The main novelties in the joint are that the metallic union of the conductors is insulated by wrapping on a single sheet of wide, impregnated paper by machine. The ends of the cable insulation are cut into a series of steps, or a taper, and knives on the machine cut the wide sheet of paper exactly to fit the steps or tap... View full abstract»

  • Voltage standardization

    Publication Year: 1927, Page(s):257 - 262
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1397 KB)

    A review of the points of view which in general influence standardization of voltages and a number of proposals of certain standards are given in this paper. The discussion pertains to classes of voltages, three-phase systems, d-c. systems, and nominal voltages. A plea is made for the use of the ratio of 1/√3 for working voltages. View full abstract»

    Records of the transients actually occurring on transmission lines of widely varying characteristics have been obtained recently with the klydonograph. 1. These records substantiate many of the theories of transients on lines. 2. They indicate the incorrectness or incompleteness of some of hese theories. 3. They suggested modifications or extensions of these latter theories. This paper is a coordi... View full abstract»

  • Isolation for fire fighting

    Fires are expensive and seriously affect electric service. Unfortunately, so long as oil and combustibles are used for insulation and so long as electrical energy behaves as it does there will always be fire hazards to trouble the industry. Progress in eliminating these hazards has, however, been made in the last few years. The principle of isolation has been used to good advantage in many parts o... View full abstract»

    1. The physical nature of ionization in a corona discharge in air is studied; by means of the corona spectrum, the saturation current in air around the corona voltage, and the influence of the material of the wire on the saturation current. The results indicate that nitrogen only is ionized in a corona discharge in air; that the ionization of the nitrogen results in the separation of an electron f... View full abstract»

    During two years' service in a five-mile stretch of the New York State Barge Canal at Utica, electric buoy lamps have shown that they cost $15 a year as compared with $65 for oil lamps which need inspection and attention daily. Fewer electrics are needed because they are brighter. View full abstract»

    H. E. Mendenhall: I should like to ask Mr. Carroll one question. Two years ago, Professor Sorenson discussed Doctor Ryan's paper and he had a theory that this corona loss might be caused by the positive ions not traveling as far as the negative ions. I should like to ask if they were able to determine whether or not the space charge is out further when it is negative than it is when positive? View full abstract»

    F. L. Stone: Mr. Harrington is to be congratulated on the excellent way in which he has presented to the electrical engineers the very serious problem of mine electrification. It is very evident from Mr. Harrington's description of the conditions that electrification of mines must go on and mining machinery must be electrically driven; otherwise mining costs would be prohibitive.

    J. E. Heller: It might be of interest to point out some applications in the West of the developments described by Mr. Jacobs. The longest circuits in the West include those from San Francisco to Seattle, Denver and Salt Lake City. The Seattle circuits are about 950 mi. in length and are made up of carrier channels to Portland, open wire from Portland to Tacoma and cable from Tacoma to Seattle. A l... View full abstract»

    A new spirit of decorative art is today permeating France. As in other fields, it found striking expression in the design and use of lighting fixtures at the International Exposition of Decorative Arts held last year in Paris. The ornamentation and the lighting of a room are inseparable. Recognizing this, artists and decorators often use light as the determining element in their decorative schemes... View full abstract»

    “Lighting” was chosen this year as the subject of the annual exhibit of the Academy at Rotterdam, Holland. With the assistance of several organizations, including the Dutch Illuminating Engineering Society, a demonstration of lighting effects and of good and bad lighting as it applied to a number of the more usual services was arranged. The exhibit also included displays relating to ... View full abstract»
