  • Magnetism and the Rare-Earth Metals

    Publication Year: 1959 , Page(s): 93 - 105

    After a brief outline of the history of the discovery and separation of the rare-earth elements, the modern theory of paramagnetism is summarized, and its application to these metals is discussed, with particular attention paid to the way in which deviations from the simple laws of paramagnetism at low temperatures can yield information on the types of magnetic interaction which exist in them. The... View full abstract»

    This paper considers the problem of optimum design of the impedance matching, lumped-parameter, wide-band transformer model with all transmission zeros at infinity. The spiral-tape-winding transformer is compared with the wire-winding transformer with an electrostatic screen, and it is shown that the former has no advantage over the latter except (perhaps) at quite low impedance levels. The low-pa... View full abstract»

    The motion of submerged repeaters during laying and pick-up in deep water has been investigated and the results are presented. An attempt has been made to gather together in a systematic way the very scattered references to long-term deterioration problems affecting the choice of materials of which components are made. Component testing procedure is discussed and special features of individual com... View full abstract»

  • Metal and Oxide Film Potentiometers

    Publication Year: 1959 , Page(s): 105 - 108

    Recent developments in resistors and potentiometers of the noble metal and metal oxide film types are described. Photographic methods of producing "meandered" resistance paths in the two types have been developed, as well as means of rhodium reinforcing the track portions to improve the wear characteristics, and in the case of oxide films, to reduce the contact resistance against the wiper. The re... View full abstract»

  • Recent Developments in Fixed Resistors

    Publication Year: 1959 , Page(s): 109 - 113

    The commoner types of resistor used in electronic apparatus are discussed in terms of recent developments. In most cases developments have been largely progressive improvements without fundamental changes in the component. Some of the more interesting of recently developed types are also considered, these being metal films and metal oxide films and combinations. Their potentialities are outlined. ...

    The salient characteristics of capacitors having dielectrics of polystyrene, polythene, polytetrafiuorethylene, and polyethylene terephthalate are enumerated, and the current trends are indicated. Test results on experimental capacitors made with the new polycarbonate film are also quoted. View full abstract»

    Since the demonstration of the possibility of achieving very low noise amplification of signals in the centimetric wavebands, a great deal of work has been carried out in various laboratories with a view to producing and testing devices. The major part of the present article focuses attention on one particular device, the three-level solid-state maser. The physical principles underlying the proces... View full abstract»

  • A Comparison of the Noise and Voltage Coefficients of Precision Metal Film and Carbon Film Resistors

    Publication Year: 1959 , Page(s): 58 - 62
    Request Permissions | Click to expandAbstract | PDF file iconPDF (776 KB)  

    Measurements of the current noise and voltage coefficient are given for metal film and carbon film resistors. In general, the noise power in the metal resistors was less than that in the carbon by a factor of 103, although a few of the former type were very noisy. For many typical applications in and below the audio spectrum the current noise in a large fraction of the metal resistors w... View full abstract»

  • Some Recent Developments in Magnetic Alloys

    Publication Year: 1959 , Page(s): 119 - 122
    Request Permissions | Click to expandAbstract | PDF file iconPDF (584 KB)  

    The magnetic properties and use of some conventional and new alloys are discussed. The control which can be exercised on the switching properties by varying composition and treatment is indicated and a very fast switching alloy described. The abnormally low permeability of very thin strip is explained; it can be avoided by keeping material and furnace atmosphere pure. The latest aluminum-iron and ... View full abstract»
