  • Load characteristics of a submerged-arc silicon-smelting furnace

    Publication Year: 1959, Page(s):273 - 276
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2736 KB)

    SUBMERGED-arc furnaces have been in commercial operation for more than 50 years. However, the literature tells little about what they require from the supplier of the electric energy or what effects they have on the supply system. A silicon-smelting furnace is typical of these operations. In fact, this process is generally considered to be one of the most exacting in its demands for precise operat... View full abstract»

    THERE are two principal methods of separating suspended particles from air: mechanical separation and electrostatic precipitation. Mechanical separation includes dry-type filters, cyclones, water scrubbers, and gravity settling chambers. Dry-type filters are commonly used in air conditioners. Mechanical separators depend on inherent differences in size and density existing between particles and th... View full abstract»

    THE SUCCESSFUL application of cathodic protection to undergound structures in the crowded confines of a large metropolitan city presents problems of cathodic protection co-ordination certainly more acute and perplexing than those ordinarily encountered in crosscountry work. It is frequently very difficult to find a suitable location for a ground bed in a particular area requiring protection. View full abstract»

    Publication Year: 1959, Page(s):286 - 291
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2203 KB)

    THE d-c variable voltage drive for diesel or gas-electric drilling rigs has gained considerable popularity since the introduction of lightweight low-cost electric equipment. However, quite often not sufficient advantage has been taken of the intermittent capability of the generators and motors, both from an application and operational standpoint. This paper presents information derived from an ana... View full abstract»

  • Three-phase induction heating coils

    Publication Year: 1959, Page(s):291 - 294
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1289 KB)

    IN THE 60-cycle field of induction heating a 3-phase system is desirable. The advantages of 3-phase power is fairly obvious. In most cases a large amount of power is required and a balanced 3-phase load is very practical. Hence, 3-phase induction heating coils have been used to a large extent in 60-cycle heating of aluminum and brass. Since the size of stock to be heated is large in cross section,...

  • Stability criteria for instrument servomechanisms with coulomb friction and stiction

    Publication Year: 1959, Page(s):294 - 297
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1342 KB)

    IT IS WELL KNOWN that relative motion between rubbing surfaces is opposed by friction forces. In general, a force directly proportional to velocity is produced by a component known as ¿viscous friction.¿ Normally, another component, the coulomb friction force C, produces a force that is essentially constant regardless of velocity. In addition, if the surfaces are initially stationary, the force ... View full abstract»

    Variable-speed constant-frequency (vscf) generator systems are studied as an extension of well-known vscf motor technology. The vscf generator systems become practical for aircraft main generating systems when the commutator function is performed by semiconductor devices. It is concluded that the best scheme for this application is one using as the main generator a wound rotor induction machine op... View full abstract»

    EVER since the advent of a-c systems in aircraft, designers have been increasingly led to consider methods of obtaining constant frequency from variable-speed sources, as the aircraft engine is usually at least two to one in speed range. The first device to obtain constant speed from a variable-speed source was under development for many years, and it is only recently that it has been considered r... View full abstract»

    IT CAN logically be assumed that within 5 years it will be possible to project into orbit a 20,000-lb (pound) vehicle, five times as heavy as the largest satellite now in orbit. This payload capability is a necessary intermediate step in the long-range program leading to manned space flight. View full abstract»

    AS AN initial step toward the eventual realization of a completely static system for converting solar radiation to electric power, the analysis and testing of a laboratory thermoelectric generator has been undertaken. A description of the over-all project is given in reference 1. An essential part of the over-all system is the combination of reflector and absorber used to collect and concentrate t...

  • A practical standard transistorized optimum response controller

    Publication Year: 1959, Page(s):337 - 345

    The principle of nonlinear optimum response control has found a new and unique application in the development of a standard controller. The transistorized controller can work in a great variety of feedback systems because it has negligible time delay. Optimum response to a specified step input can be obtained very easily by experiment because linear switching is used. The response is still nearly ... View full abstract»

    With the coming space age, considerable attention is being focused upon the problem of supplying secondary power to the vehicles of the future. It is anticipated that future space vehicles may perform missions which will require months and perhaps years to complete. Requirements for the secondary power source serving these vehicles will be very stringent. Weight will be at a premium, therefore, th... View full abstract»

    VEHICLES traveling at hypersonic velocities in a gaseous atmosphere will be surrounded by a shock-induced high-temperature sheath. As a result of the high temperature, the gaseous sheath has an electron density greater than that of the ambient atmosphere. Since the craft will be immersed in a high-temperature envelope, both it and its components will be subjected to unusual temperatures. Fig. 1 in... View full abstract»

    THE COMPLEXITY of present-day high-performance aircraft and missiles is demanding better reliability of its various subsystems. A considerable amount of the equipment, such as guidance and flight control equipment, depends entirely upon the electric power system. Therefore, the electric power system is of primary importance in the over-all reliability of the aircraft. View full abstract»

    A WESTERN refinery was adding a new catalytic reformer unit to existing facilities. The chemical process involved, which had a platinum catalyst worth $250,000 in suspension, was dependent upon mechanical power to a compressor. This was a vital drive where loss of mechanical power for a short time meant loss of the catalyst as well as loss of production. View full abstract»
