    The flow of energy is traced in a typical, somewhat idealized 3-phase alternator, using an adaptation of Poynting's vector together with a discussion of this procedure. Following the specification of the electromagnetic field, quantitative analysis of the flow of energy in the gap, at the surface of the rotor, and into and out of the stator conductors is presented under no load, at a unity-power-f...

  • Torque requirements of a radar antenna

    Publication Year: 1954, Page(s):15 - 18
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2244 KB)

    Results of wind tunnel tests on an experimental radar antenna are discussed. The torque required to rotate the antenna was seen to vary with the azimuth position, the elevation angle, the pivot location, the rotating speed, and the wind velocity. A correlation of the data based on dimensionless parameters was found. View full abstract»

  • Application and transmission features of a new 12-channel open-wire carrier system

    Publication Year: 1954, Page(s):18 - 27
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3169 KB)

    A new, miniaturized, 12-channel open-wire carrier system, the Lenkurt 45A system, is described. For use in the 40-to 150-kc frequency region, it co-ordinates fully in level and frequency allocations with present Lenkurt 42C and Western Electric J carrier systems using this frequency space. Because of the inclusion of 2-pilot regulation for flat and slope gain control, supplemented by channel regul... View full abstract»

    THE United States Army Signal Corps has recently added another chapter to the colorful history of military communications. On Dec. 17, 1952 at Fifth Army Headquarters, Chicago, Ill., the Signal Corps placed in service its new teletypewriter switching center which automatically switches messages through the Army's vast world-wide teletypewriter network. Sufficient time has passed since the system w... View full abstract»

  • Electrical properties of microcrystalline selenium

    Publication Year: 1954, Page(s):38 - 45
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (12707 KB)

    THE increasing number of electronic applications for semiconducting materials which have been developed in recent years, coupled with the discovery of the transistor action of these materials, has been largely responsible for the vast amount of research data which have been published on semiconductors. Most of the work has been done on germanium and silicon and as a result these data have led to a... View full abstract»

  • Instantaneous electrical characteristics of selenium rectifiers

    Publication Year: 1954, Page(s):45 - 49
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1227 KB)

    IN POWER applications of selenium rectifiers the reverse characteristics of the selenium cell are of interest only in so far as they affect the heat generated within the cell and thus the efficiency and the current rating of the cell as dictated by its heat-dissipation capabilities. In more critical applications, however, the detailed reverse characteristics of the cell must be considered; this is... View full abstract»

  • A new portable telegraph transmission measuring set

    Publication Year: 1954, Page(s):59 - 62

    THE provision of good telegraph service requires that the circuits be designed, engineered, and maintained so as to afford good transmission quality. The measurement of a single quantity, known as telegraph distortion,1 at the receiving end is sufficient to establish the transmission quality since it contains all signal degrading effects, such as interference, poor relay performance, and wave-shap...

  • An annular wave-guide rotary joint with wave-guide feed

    Publication Year: 1954, Page(s):62 - 66

    THERE are many engineering problems in the field of electronics which require a good method of transmitting radio frequency energy from a fixed unit to a rotating unit. For radio frequencies at which wave guides are normally employed, the rotary joint herewith described is especially suitable, particularly where there is a multiplicity of independent transmission lines involved in a relative motio...

    THE use of tungsten wire for the sensing element of a resistance thermometer is not new to the art. However, to the best knowledge of the authors, this thermometer, Fig. 1, is the first successful one with stabilities as good as, or better than, platinum. View full abstract»

  • Fast-response magnetic amplifiers

    Publication Year: 1954, Page(s):69 - 75
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1827 KB)

    AMPLIFIERS for use in automatic control systems should feature high gain, high-power output, and fast response along with light weight and reliable operation. In electrical systems magnetic amplifiers are gaining favor because of their rugged construction, but until recently the response time of magnetic amplifiers has been relatively unsatisfactory for small servo systems. Amplifiers are often ch... View full abstract»

    A NEW line of carrier equipment known as the class 45 has been developed with a view toward application on open-wire lines, paired and coaxial cable, and radio systems. Both mechanical and electrical design have been co-ordinated for each of the systems in these respective applications. In this paper, the 45A system arrangements for open-wire use are described. In basic terminal equipment, no diff... View full abstract»

  • The use of instantaneous point sources or Green's functions in evaluating electromagnetic fields

    Publication Year: 1954, Page(s):82 - 88
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1679 KB)

    IN a previous paper1 it was shown how expressions for vector potential could be derived from corresponding values of scalar potential for a point source; these expressions are given in the author's Tables of Green's Functions.2 It was then shown how these vector-potential expressions could be used to derive the fields due to uniformly magnetized disks, or due to coils, building them up from magnet...

  • Analysis of linear time-varying circuits by the Brillouin-Wentzel-Kramers method

    Publication Year: 1954, Page(s):93 - 96
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (842 KB)

    This paper presents a general mathematical technique for studying the response of linear time-varying circuits that contain parameters whose magnitudes vary in a periodic manner with the time. The method presented is based on the Brillouin-Wentzel-Kramers (BWK) procedure, which has been widely used in connection with problems of wave mechanics. This method gives approximate results with very littl... View full abstract»
