    Measurement of the measuring stop position is by an electromagnetic digitizer and the control system is built-up from standard plug-in transistor logic units. The drive of the measuring stop is by a two speed pole amplitude modulated type pole-changing induction motor. Use is made of a fast traverse, slow approach cycle, and the final approach is always from one direction to eliminate back-lash er... View full abstract»

    A study has been made of the effect of ice cover on long range 100 n miles) acoustic propagation at low frequencies in an area having an approximate constant water depth of 30 fathoms. Explosive charges weighing 1.8 lb dropped from an aircraft were used as acoustic sources and the acoustic pulses were detected on a bottomed barium titanate hydrophone. Comparative measurements have been made with i... View full abstract»

    The paper discusses the usefulness of ßf-excited sources of electro-magnetic radiation (bremsstrahlung) in a radiation absorption measuring system, designed primarily to indicate continuously the sulphur content of refinery hydrocarbon streams. A conventional Geiger counter/ratemeter system is used to give simplicity of design and reliability of operation of the detector/indicator equipment. An a... View full abstract»

    A method of phase measurement is described which does not appear to have been used before at frequencies in the audio range. The general principle is stated, the apparatus is described and a curve comparing the measured and predicted phase response of a simple network is given. View full abstract»

  • Man and machine in the extraction and use of radar information

    Publication Year: 1963, Page(s):309 - 316
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (997 KB)

    Modern primary and secondary radars can potentially provide far more information than can be directly displayed¿or can be absorbed by the user. Hence there is a strong prima facie case for automatic data extraction. Even the filtered information arising from automatic extraction cannot be efficiently used by the unaided human operator. However, the use of a surveillance radar picture in air or se... View full abstract»

    The basic recognition criteria employed in the extraction of radar target data are described and the application of these criteria in human and automatic radar data extraction systems is discussed. The details of two experimental auto-extraction systems are given. One system involves the use of storage tubes and the other employs fused quartz delay lines as the necessary storage medium. Qualitativ... View full abstract»

    The way the medium controls sound reception in shallow water is discussed generally, and illustrated by some North Sea experiments with explosion sources. The ray and mode theories are introduced, and it is shown where it is convenient to change from one to the other. Transmission loss is the most important parameter, and is least around 200 c/s. Time dispersion is mainly due to the dispersion in ... View full abstract»

    Situations often occur in industry where several machines or operatives have a common source of material. If demands for more materials are dealt with in random sequence, or in accordance with a fixed routine, there will be cases where a machine or operator runs right out of material while others get their demands met more quickly than necessary. A solution to this problem is to have an electronic... View full abstract»
