    [br]
    b. 1933 Portland, Oregon, USA
    [br]
    American electronics engineer who developed professional systems for noise reduction.
    [br]
    He was employed by Ampex Corporation from 1949 to 1957 and received a BSc in electrical engineering from Stanford University in 1957. He studied in England and received a PhD in physics from Cambridge University in 1961. He was a United Nations adviser in India 1963–5 and established the Dolby Laboratories in London in 1965. The Dolby Laboratories continuously developed systems for background-noise reduction, and in 1966 introduced Dolby A for professional tape and film formats. In 1968 Dolby B was developed and quickly found its use in the Philips Compact Cassette, which had become the new consumer medium for music. In 1981 Dolby C was an improvement designed for the consumer market, but it also was used in professional video equipment. In 1986 Dolby SR was introduced for professional sound recording. It is a common feature that the equipment has to be in a good state of calibration in order to obtain the advantages of these compander systems.

  • 13 Braun, Karl Ferdinand

    [br]
    b. 6 June 1850 Fulda, Hesse, Germany
    d. 20 April 1918 New York City, New York, USA
    [br]
    German physicist who shared with Marconi the 1909 Nobel Prize for Physics for developments in wireless telegraphy; inventor of the cathode ray oscilloscope.
    [br]
    After obtaining degrees from the universities of Marburg and Berlin (PhD) and spending a short time as Headmaster of the Thomas School in Berlin, Braun successively held professorships in theoretical physics at the universities of Marburg (1876), Strasbourg (1880) and Karlsruhe (1883) before becoming Professor of Experimental Physics at Tübingen in 1885 and Director and Professor of Physics at Strasbourg in 1895.
    During this time he devised experimental apparatus to determine the dielectric constant of rock salt and developed the Braun high-tension electrometer. He also discovered that certain mineral sulphide crystals would only conduct electricity in one direction, a rectification effect that made it possible to detect and demodulate radio signals in a more reliable manner than was possible with the coherer. Primarily, however, he was concerned with improving Marconi's radio transmitter to increase its broadcasting range. By using a transmitter circuit comprising a capacitor and a spark-gap, coupled to an aerial without a spark-gap, he was able to obtain much greater oscillatory currents in the latter, and by tuning the transmitter so that the oscillations occupied only a narrow frequency band he reduced the interference with other transmitters. Other achievements include the development of a directional aerial and the first practical wavemeter, and the measurement in Strasbourg of the strength of radio waves received from the Eiffel Tower transmitter in Paris. For all this work he subsequently shared with Marconi the 1909 Nobel Prize for Physics.
    Around 1895 he carried out experiments using a torsion balance in order to measure the universal gravitational constant, g, but the work for which he is probably best known is the addition of deflecting plates and a fluorescent screen to the Crooke's tube in 1897 in order to study the characteristics of high-frequency currents. The oscilloscope, as it was called, was not only the basis of a now widely used and highly versatile test instrument but was the forerunner of the cathode ray tube, or CRT, used for the display of radar and television images.
    At the beginning of the First World War, while in New York to testify in a patent suit, he was trapped by the entry of the USA into the war and remained in Brooklyn with his son until his death.

    [br]
    b. 13 April 1892 Brechin, Angus, Scotland
    d. 6 December 1973 Inverness, Scotland
    [br]
    Scottish engineer and scientific adviser known for his work on radar.
    [br]
    Following education at Brechin High School, Watson-Watt entered University College, Dundee (then a part of the University of St Andrews), obtaining a BSc in engineering in 1912. From 1912 until 1921 he was Assistant to the Professor of Natural Philosophy at St Andrews, but during the First World War he also held various posts in the Meteorological Office. During. this time, in 1916 he proposed the use of cathode ray oscillographs for radio-direction-finding displays. He joined the newly formed Radio Research Station at Slough when it was opened in 1924, and 3 years later, when it amalgamated with the Radio Section of the National Physical Laboratory, he became Superintendent at Slough. At this time he proposed the name "ionosphere" for the ionized layer in the upper atmosphere. With E.V. Appleton and J.F.Herd he developed the "squegger" hard-valve transformer-coupled timebase and with the latter devised a direction-finding radio-goniometer.
    In 1933 he was asked to investigate possible aircraft counter-measures. He soon showed that it was impossible to make the wished-for radio "death-ray", but had the idea of using the detection of reflected radio-waves as a means of monitoring the approach of enemy aircraft. With six assistants he developed this idea and constructed an experimental system of radar (RAdio Detection And Ranging) in which arrays of aerials were used to detect the reflected signals and deduce the bearing and height. To realize a practical system, in September 1936 he was appointed Director of the Bawdsey Research Station near Felixstowe and carried out operational studies of radar. The result was that within two years the East Coast of the British Isles was equipped with a network of radar transmitters and receivers working in the 7–14 metre band—the so-called "chain-home" system—which did so much to assist the efficient deployment of RAF Fighter Command against German bombing raids on Britain in the early years of the Second World War.
    In 1938 he moved to the Air Ministry as Director of Communications Development, becoming Scientific Adviser to the Air Ministry and Ministry of Aircraft Production in 1940, then Deputy Chairman of the War Cabinet Radio Board in 1943. After the war he set up Sir Robert Watson-Watt \& Partners, an industrial consultant firm. He then spent some years in relative retirement in Canada, but returned to Scotland before his death.

    En el presente, la traducción más común de soler es el verbo principal más usually: Suele volver a las diez. He usually comes back at ten.
    Para referirnos a costumbres en el pasado hay que usar to use to o would. Would expresa acciones repetidas, mientras que to use to describe también estados o situaciones: Antes íbamos/solíamos ir a la playa en tren. We used to/would go to the beach by train.
    No confundas to use to (do sthg) con to be used to (doing sthg), que significa estar acostumbrado y, al contrario que to use to, puede usarse también en presente: Estoy acostumbrado a coger el metro. I'm used to taking the metro. ➣ Ver nota en accustom

  • 19 Hounsfield, Sir Godfrey Newbold

    SUBJECT AREA: Medical technology
    [br]
    b. 28 August 1919 Newark, Nottinghamshire, England
    [br]
    English scientist, inventor and developer of computer-assisted tomography (CAT) scanning technique of radiographic examination.
    [br]
    After an education in Newark and London in radiocommunications and radar, Hounsfield volunteered and served in the RAF during 1939–45. He was a lecturer at Cranwell Radar School from c.1942 to 1945. From 1947 to 1951 he undertook further study in electrical and mechanical engineering, and in 1951 he joined Electrical and Musical Instruments (EMI) Ltd, where he led the design team for the first British all-transistor computer (EMIDEC, 1959). In 1969–72 he invented and developed the EMI computerized transverse axial tomography scanner system of X-ray examination; this, while applicable to other areas of the body, particularly permitted the elimination of difficulties presented since the earliest days of X-ray examination in the examination of the cranial contents.

  • 20 Williams, Sir Frederic Calland

    [br]
    b. 26 June 1911 Stockport, Cheshire, England
    d. 11 August 1977 Prestbury, Cheshire, England
    [br]
    English electrical engineer who invented the Williams storage cathode ray tube, which was extensively used worldwide as a data memory in the first digital computers.
    [br]
    Following education at Stockport Grammar School, Williams entered Manchester University in 1929, gaining his BSc in 1932 and MSc in 1933. After a short time as a college apprentice with Metropolitan Vickers, he went to Magdalen College, Oxford, to study for a DPhil, which he was awarded in 1936. He returned to Manchester University that year as an assistant lecturer, gaining his DSc in 1939. Following the outbreak of the Second World War he worked for the Scientific Civil Service, initially at the Bawdsey Research Station and then at the Telecommunications Research Establishment at Malvern, Worcestershire. There he was involved in research on non-incandescent amplifiers and diode rectifiers and the development of the first practical radar system capable of identifying friendly aircraft. Later in the war, he devised an automatic radar system suitable for use by fighter aircraft.
    After the war he resumed his academic career at Manchester, becoming Professor of Electrical Engineering and Director of the University Electrotechnical Laboratory in 1946. In the same year he succeeded in developing a data-memory device based on the cathode ray tube, in which the information was stored and read by electron-beam scanning of a charge-retaining target. The Williams storage tube, as it became known, not only found obvious later use as a means of storing single-frame, still television images but proved to be a vital component of the pioneering Manchester University MkI digital computer. Because it enabled both data and program instructions to be stored in the computer, it was soon used worldwide in the development of the early stored-program computers.
