    This paper describes an analytical and experimental study of a self-cascade single-frame brushless induction motor, using a rectifier- inverter to control speed by slip-power pump back to the line. Steady- state analyses of asynchronous and synchronous performance and test results of a special machine wound for the study are presented. The effect of machine parameters, windings, and construction i... View full abstract»

    A systematic method of designing electrical sequential circuits for industrial machine control is presented. A clear set of rules has been laid down for the method, with the result that a circuit can be designed on a step by step basis without much mental effort. The method is simple to understand, easy to apply, and presents a very economical and reliable solution to a large proportion of the seq... View full abstract»

  • Identification of an Industrial Process by Numerical Inversion of the Laplace Transform

    Publication Year: 1978, Page(s):111 - 115
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1691 KB)

    A practical application of a novel parameter identification technique for industrial process control systems is presented. The solution algorithm is based on numerical inversion of the Laplace Transform, as proposed by Bellman, et al. Its application with the aid of a minicomputer (or a desk calculator) is fairly easy and fast. Using this method, process gain and time-constants of an electric furn... View full abstract»

    An adjustable-speed drive comprising a slip-ring induction motor and a cycloconverter-type thyristor-commutator in its rotor circuit has been developed. The thyristor-commutator acts as a frequency-changer like a conventional commutator in a stator-fed ac commutator motor, converting line-frequency injected voltages directly to slip-frequency at the rotor terminals. The circuit permits a reversibl... View full abstract»

  • A Single-Phase Self-Oscillating Thyristor Inverter

    Publication Year: 1978, Page(s):123 - 127
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1488 KB)

    A single-phase self-oscillating square-wave inverter using silicon controlled rectifiers, which can operate at any load power factor is described. The inverter can operate either in a fixed-frequency fixed- voltage mode or with a variable-frequency variable-voltage mode within the commutation capability, where the frequency to voltage ratio remains constant. The circuit has higher power handling c... View full abstract»

    As a result of increasing fuel prices, many cement producers show interest in converting existing wet process cement plants to the more fuel efficient dry process. With emphasis that goes beyond the potential fuel saving, the question of how the economic feasibility of twelve different conversion methods can be calculated and compared is dealt with, as is the question of how the economic feasibili...

    Improving the productivity of a container manufacturing operation requires reducing the art in the operation of the process and adding process controls. Reducing the art, in turn, requires providing machine control mechanisms that will provide a consistent and repeatable machine operation independent of operator experience. For a glass container line the control mechanisms must provide for a consi... View full abstract»

    A facsimile recorder developed at Teletype Corporation utilizes a squirting ink jet as the printing device. The recorder produces copy having 200 lines per inch resolution on ordinary paper at the rate of 50 pages per hour. The design features a disposable ink system which can be replaced by an operator. The technique used for generating gray tones is readily adaptable to color printing. View full abstract»

    Liquid issuing from the bore of a metallic capillary tube maintained at a high potential may, under certain conditions, be dispersed in the form of regular current pulses of charged droplets. This phenomenon is well known but not fully understood. The pulsation process is considered in some detail, and experimental data obtained during the electrostatic dispersion of pure and impure glycerol, in a... View full abstract»

    It is shown that converting your plant lighting to high- pressure sodium-now-pays dollar dividends. This is true even if your plant went on-stream last year. Lighting systems that depart from the usual are shown to save energy and therefore help profits. Treating lighting as the plant stepchild wastes your money and our energy. Planning a sound maintenance program, starting when the plant is desig... View full abstract»

    An offshore power plant and high voltage dc (HVDC) transmission to bring the generated energy ashore are described. Offshore gas fields will, in some cases, be better utilized if the gas can be burned in platform located gas turbines to generate electric power which is transmitted to shore via HVDC cable circuits. The proposed system should be considered when the distance is long, the water depth ... View full abstract»
