  • Gravitational wave astronomy: an interim survey

    Publication Year: 1971, Page(s):391 - 397
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1134 KB)

    The concept of gravitational radiation is introduced and the experiments of Weber are described. The magnitude and nature of the phenomenon are discussed in the light of Einstein's theory of relativity. The basic theory of a detector is developed and the means of realization are indicated. Investigations are proceeding along these and parallel lines in many parts of the world but no definitive res... View full abstract»

  • A method of measuring pulse duration

    Publication Year: 1971, Page(s):398 - 404

    The pulse under investigation and a timing wave consisting of a succession of narrow triangular pulses of controllable frequency are simultaneously displayed on a double-beam sampling oscilloscope. Adjacent timing pulses are aligned to the leading and trailing edges of the pulse being measured; the duration of the pulse, being then identical with the period of the timing wave, is obtained from a d...

  • The television performance of the klystron amplifier

    Publication Year: 1971, Page(s):405 - 415
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1951 KB)

    The paper describes the electrical behaviour of multi-cavity klystrons, now extensively used as high-power amplifiers in u.h.f. television transmitters. The factors affecting the frequency response are reviewed, with descriptions of the particular conditions required for output coupling and cavity tuning. The response of the klystron to the television tests for non-linearity is discussed in detail... View full abstract»

    A neutrally buoyant instrument able to measure and record vertical flow, water temperature, and pressure at any oceanic depth for extended periods is described. Principles of operation, design of the measurement, recorder, recovery, acoustic telemetry, and relocation sub-systems are discussed. Special features of the electronic design are very low power consumption and circuit flexibility to adapt... View full abstract»

  • Use of an on-line digital computer for enhancement and integration of nuclear resonance spectra

    Publication Year: 1971, Page(s):421 - 429
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1038 KB)

    The paper describes the design and practical considerations involved in coupling a small digital computer to work on-line with a chemical research n.m.r. spectrometer. The various requirements of spectrometer, computer, interfacing and programming are dealt with both in general terms and in relation to the specific system employed in the present project. The effectiveness of the practical system i... View full abstract»

  • A graphic fixed storage system for a remote terminal display

    Publication Year: 1971, Page(s):430 - 434

    A series of linear elements are used to create a graphical display of a quality adequate for visual inspection. The graphic alpha-numeric character store described is a specially-constructed fast, pre-wired, closed magnetic path, transformer, read-only memory. However, the graphical techniques discussed could well be implemented by other storage methods. Experimental results and simulated displays... View full abstract»
