  • Tests of electrostatic controls for hazardous industrial applications

    Publication Year: 1952, Page(s):1 - 13
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1038 KB)

    THE destruction and casualties from fires and explosions which originate from electrostatic ignition in hazardous processes are all too well known among safety engineers and industrial management to require elaboration. The annual property loss to industry is reported to be approximately $100,000,000 exclusive of costly losses from indirect sources. These losses, as well as the injuries and deaths...

  • Induction preheating of electrolytic tin plate (or flow brightening with high-frequency rotating equipment

    Publication Year: 1952, Page(s):13 - 18
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (819 KB)

    MANY producers of tin plate, due to its large demand, are considering new or additional equipment. In order to flow brighten tin plate at high speeds, it is necessary to use high-frequency induction heating equipment. The other methods for producing tin plate, using combustible gases as a source of heat supply or resistance heating, are at present impractical at high speeds. To the author's knowle...

    THE quantitative understanding of the behavior of a human being functioning as an element of a closed-loop control system has become a matter of considerable importance in recent years. In addition to the purely military problems of high-speed flight, fire control, and similar tasks there are many situations such as automobile driving, operating machine tools, and other complicated mechanical devi...

  • Railway power contracts

    Publication Year: 1952, Page(s):24 - 26
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (167 KB)

    RAILWAY power contracts should be based upon rate schedules and general provisions that harmonize the respective interests of the power supplier and user. Elimination of the customary demand charge and the substitution therefor of a straight energy charge supplemented with a minimum bill provision appears to offer considerable assistance toward this goal. By this means railway managements would be... View full abstract»

  • A new electric locomotive for the Pennsylvania Railroad

    Publication Year: 1952, Page(s):27 - 37
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1076 KB)

    Simplicity and reliability are the keynotes of the design of the new single-phase a-c electric locomotives for the Pennsylvania Railroad. Basic components tried and proved by years of successful operation were deliberately chosen and combined into a new design. Full advantage was taken of the latest improvements in materials and manufacturing processes to create a motive power unit of high capacit... View full abstract»

    Continued and intensive developments in perfecting the ignitron rectifier for broad application in the industrial and power fields revived interest recently in using it for railway work. Extensive tests in the laboratory and on an experimental railway car have demonstrated that a locomotive using ignitron rectifiers offered promise in combining the best features of the a-c and d-c electrification ...

  • Railway electrification, diesel-electric locomotives, and some future aspects of electric traction

    Publication Year: 1952, Page(s):48 - 50
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (215 KB)

    Diesel-electric locomotives have replaced the steam locomotives in this country to a great extent and have been used in preference to railway electrification; whereas in Europe the tendency is still rather in favor of electrification. The following is a discussion for this diversity, which may be influenced by further technical developments. View full abstract»

    IMPROVED wheel-slip and wheel-lock protection for diesel-electric locomotives is a subject which has received considerable attention in the past few years. The system here described was designed to meet the proposed specifications of the Association of American Railroads. Its operation is based upon comparison of voltages which are proportional to the speed of the axles being protected. It will op... View full abstract»

    TRAFFIC congestion in our large centers of population exacts a staggering toll in inconvenience and financial loss each year. Emphasis to alleviate this condition has taken the direction of expediting the movement of vehicles. Analysis shows the fundamental problem to be that of moving people. In the light of this, co-ordinated transportation systems, such as here described, offer most attractive ... View full abstract»

    WHERE motor-generator sets are used, induction heating coils are frequently located at points remote from the high-frequency generator in a manufacturing plant. In such cases, one or more transmission lines are required. These may be either of the cable or rectangular bus bar type. A subsequent paper will consider the use of cables. The present paper deals with rectangular bus bars. Primary attent... View full abstract»

  • Application of motors to household refrigeration compressors

    Publication Year: 1952, Page(s):70 - 77
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (645 KB)

    HOUSEHOLD refrigeration has come a long way since the days when the ice came from a commercial ice-making plant, lake or river and was placed in an ice box. The first mechanical compressor consisted of a pump, belt driven by an electric motor. There were shaft seals in the pump to prevent the refrigerant and oil from escaping. The belt and shaft seals were troublesome. The manufacturers did the be... View full abstract»

  • Increased losses in a D-C motor when operated from grid-controlled rectifiers

    Publication Year: 1952, Page(s):77 - 82
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (435 KB)

    The increase in copper losses and iron losses of a d-c shunt motor when operated from grid-controlled rectifiers is studied. Fourier components of the rectifier output voltage are calculated, and the superposition principle is applied to predict copper losses. Tests were run to determine copper loss and iron loss; increased copper loss is seen to closely approximate the predicted value, and discre... View full abstract»

    THE a-c electric power generation and distribution system of the Dow Chemical Company at Midland, Mich., may be of interest to power engineers for two reasons. First, it represents the experience of a plant wide a-c system that has grown from small beginnings in a period of 23 years and has encountered and solved the problems that go with rapid growth. Second, being a chemical plant, many special ... View full abstract»

  • The writing of closed-loop control system transfer functions by inspection

    Publication Year: 1952, Page(s):90 - 94
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (383 KB)

    IN many closed-loop control systems, an analysis of the system discloses that it is possible for signal energy to traverse different paths and to be modified in a different manner in these various paths. This is in contrast to the very simplest of closed-loop systems, where the signal traverses transfer elements in cascade. The reasons for using multiple-loop systems are many. Improved linearizati...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (654 KB)

    THIS paper introduces a procedure for synthesizing servomechanisms whereby the roots of the characteristic equation can be predicted. Given a specified location in the s plane for the roots, the open-loop transfer function parameters and gain can be calculated to give those roots. Since the roots of the characteristic equation are the exponents in the expression for the transient response, it is t... View full abstract»
