    The cathode ray oscillograph frequency measurement circuit described differs from previous circuits in the use of by-pass condensers and plate leaks which permit the connection of the oscillograph to a-c. circuits having large d-c. components and which permit the use of biasing controls for shifting the position of patterns on the screen. Reference oscillators are used in conjunction with the freq... View full abstract»

    This paper describes, in an elementary manner, the various relations between distribution system characteristics and the design characteristics of the relays which are used to provide automatic control for the so-called automatic, low-voltage, a-c. network distribution system. In the first part of the paper the general principles of operation of the relays and the limits of magnitude of the variou... View full abstract»

    1. Radio broadcasting involves a system of electrical distribution in which dependent relations exist between the transmitting station, the transmitting medium and the receiving station. 2. The attenuation and fading which attend the spreading out of broadcast waves are considered. The attenuation of overland transmission is shown to be, on the whole, very high and to vary over a wide range depend... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (5321 KB)  

    This paper deals primarily with the illumination of modern large classification yards of the hump type in which the traffic is in one direction. Floodlighting is advocated as the most generally satisfactory system, and various arrangements, to meet the different conditions of yard layout, space available, etc., are described.

  • Recent progress in distribution practise of the Brooklyn Edison Company, Inc.

    Publication Year: 1927 , Page(s): 38 - 45
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2494 KB)  

    Changes in the transmission and distribution system of the Brooklyn Edison Company during the past four years are briefly described and mention is made of the effect of these changes on the system's efficiency. In 1927 a low-voltage, a-c. network will be installed and this will be extended to care for the load growth until it becomes the principal supply system for low-tension energy in Brooklyn. ...

    The present position in regard to powerful motor headlights is decidedly unsatisfactory. These powerful beams, projected in a restricted radius on pedestrians and other road users, are a source of profound irritation and something will have to be done to regularize or provide an alternative to their use. What is the remedy? Mr. Edward Fryer, of the Automobile Association, states that in New York t... View full abstract»

    The desirable characteristics of automatic switching units designed for application in secondary a-c. distribution networks are discussed in this paper. Descriptions are given of units designed for wall mounting and for manhole installation. These units are connected to the low-voltage side of the network transformer for the purpose of automatically disconnecting a transformer from the low-voltage... View full abstract»

    Low voltage a-c. networks are coming into use as a means of providing a source of power having the dependability of the Edison d-c. network, and at the same time having the efficiency which can be obtained by supplying power from high voltage feeders with transformers located near the point of utilization. As in the case of d-c. networks, it is assumed that all trouble on the network itself will b... View full abstract»

    THIS method applies to rotating electrical machines having rectangular slots and trapazoidal teeth sections. If any apparent tooth density at the widest section be assumed, then a quick and reasonably accurate determination of the corresponding no-load field ampere-turns may be made. View full abstract»

    In earlier publications of the department, such as “Super Power Studies in Northeastern Section of the United States,” great emphasis was laid upon the possibilities of the elimination of waste which lay in the transformation of the power industry through the discoveries in the science of long-distance transmission and their application by large central generating plants feeding larg...

    STEPHEN GRAY AND FRANKLIN IT is now two hundred years since Stephen Gray discovered that an electrical charge will move with great rapidity along certain substances called conductors today. The motion of electricity began then to attract the attention of the natural philosopher, and it became the subject of many scientific researches, particularly after Franklin had demonstrated that lightning is ...

    E. Roth : Very interesting remarks have been made by Messrs W. F. Dawson, B. L. Barns, P. A. Borden, and C. J. Fechheimer concerning the application of the method which H. M. Hobart demonstrated in 19132 for the determination of the losses in totally enclosed and ventilated electric machines, by the calibration of the air circuit which permits elimination of the measurement of rate in flow of the ...

    M. I. Pupin: This paper recalled to my mind the first paper which I read relating to an a-c. circuit in which a simple harmonic force is impressed and the resulting current is complex harmonic. It was a paper written by the late Professor Rowland of Johns Hopkins, about thirty-eight years ago. View full abstract»

    W. S. Lee: Referring to interconnection in the Southern States, this interconnection has been in effect something like 15 to 18 years. I am afraid that this committee is going to get on dangerous grounds when they try to have the entire area controlled by devices from one point. View full abstract»

    W. A. Del Mar: Mr. Hoover's main thesis is based on certain experimental curves obtained by K. W. Wagner and showing the relation between volts and amperes in various dielectrics. In a discussion of another paper which took place the same year Mr. Peaslee2 indicated that these curves could be interpreted in terms of volts and current density. Mr. Hoover makes a third step; namely, that ... View full abstract»

    In comparatively few years, the modern motor car has evolved from a machine that was merely a motor driven carriage. Earlier automobiles provided merely the essentials of transportation. The chief concern was to make a car that would be dependable, one that would get you there and back. The motor car of today is not only highly dependable, refined in its mechanical features and smooth in performan... View full abstract»
