  • 21 Pilkington, Sir Lionel Alexander Bethune (Alastair)

    SUBJECT AREA: Chemical technology
    [br]
    b. 7 January 1920 Calcutta, India
    [br]
    English inventor of the float-glass process.
    [br]
    Pilkington was educated at Sherborne School and Trinity College, Cambridge, where he graduated in mechanical science. He spent one year at Cambridge followed by war service, which lasted until 1945. He returned to complete his degree and then joined Pilkington, the well-known glass manufacturer at St Helens' Lancashire, in 1947. Sir Alastair is not, however, related to the Pilkington family of glassmakers.
    The forming of perfectly flat glass that retained its fire finish had eluded glassmakers for centuries. Until the 1950s the only way of making really flat glass was to form plate glass by continuous casting between steel rollers. This destroyed the fire finish, which had to be restored by expensive grinding and polishing. The process entailed the loss of 20 per cent of good glass. The idea of floating glass on molten metal occurred to Sir Alastair in October 1952, and thereafter he remained in charge of development until commercial success had been achieved. The idea of floating molten glass on molten tin had been patented in the United States as early as 1902, but had never been pursued. The Pilkington process in essence was to float a ribbon of molten glass on a bath of molten tin in an inert atmosphere of nitrogen, to prevent oxidation of the tin. It was patented in Britain in 1957 and in the USA two years later. The first production glass issued from the plant in May 1957, although the first good glass did not appear until July 1958. The process was publicly announced the following year and was quickly taken up by the industry. It is now the universal method for manufacturing high quality flat glass.
    Having seen through the greatest single advance in glassmaking and one of the most important technological developments this century, Sir Alastair became Chairman of Pilkingtons until 1980 and President thereafter.

  • 22 Watkins, Alfred

    [br]
    b. 1854 Hereford, England
    d. 7 April 1935 Hereford, England
    [br]
    English photographer who developed the first practical exposure-measuring system.
    [br]
    His first patent was granted on 27 January 1890 and described a method of measuring the "actinic" value of light as a means of determining exposure. A strip of sensitized paper which darkened on exposure to light was used, and the time taken for it to darken to match a standard tint was measured. This time could be used to calculate the necessary exposure time, taking into account the speed of the plate, shutter speed and aperture. Watkins marketed a number of these actinometer designs, of which the most popular was the Watkins Bee Meter, which was in a pocket-watch form, introduced in 1903 and remaining on sale until 1939. Watkins was concerned that photographers recognize that exposure measurement had to take into account the effect of development time and temperature. In 1893 he devised the concept of the "Watkins Factor": he showed that when plates were developed by inspection, as was the practice at the time, a fixed relationship existed between the time of the first appearance of the image and the total time required to give a fully developed negative. The Watkins Factor was the figure that the first time must be multiplied by to give the second time. Watkins published tables of factors for different brands of plates and for different developers, and marketed various aids such as specially calibrated thermometers and clocks, as aids in using "Fac-torial Development" to give consistent negatives. After the early years of the twentieth century Watkins gave up direct participation in photography and devoted his time to a variety of interests, including the plotting of ley lines in England.

  • 32 Berliner, Emile

    SUBJECT AREA: Recording
    [br]
    b. 20 May 1851 Hannover, Germany
    d. 3 August 1929 Montreal, Canada
    [br]
    German (naturalized American) inventor, developer of the disc record and lateral mechanical replay.
    [br]
    After arriving in the USA in 1870 and becoming an American citizen, Berliner worked as a dry-goods clerk in Washington, DC, and for a period studied electricity at Cooper Union for the Advancement of Science and Art, New York. He invented an improved microphone and set up his own experimental laboratory in Washington, DC. He developed a microphone for telephone use and sold the rights to the Bell Telephone Company. Subsequently he was put in charge of their laboratory, remaining in that position for eight years. In 1881 Berliner, with his brothers Joseph and Jacob, founded the J.Berliner Telephonfabrik in Hanover, the first factory in Europe specializing in telephone equipment.
    Inspired by the development work performed by T.A. Edison and in the Volta Laboratory (see C.S. Tainter), he analysed the existing processes for recording and reproducing sound and in 1887 developed a process for transferring lateral undulations scratched in soot into an etched groove that would make a needle and diaphragm vibrate. Using what may be regarded as a combination of the Phonautograph of Léon Scott de Martinville and the photo-engraving suggested by Charles Cros, in May 1887 he thus demonstrated the practicability of the laterally recorded groove. He termed the apparatus "Gramophone". In November 1887 he applied the principle to a glass disc and obtained an inwardly spiralling, modulated groove in copper and zinc. In March 1888 he took the radical step of scratching the lateral vibrations directly onto a rotating zinc disc, the surface of which was protected, and the subsequent etching created the groove. Using well-known principles of printing-plate manufacture, he developed processes for duplication by making a negative mould from which positive copies could be pressed in a thermoplastic compound. Toy gramophones were manufactured in Germany from 1889 and from 1892–3 Berliner manufactured both records and gramophones in the USA. The gramophones were hand-cranked at first, but from 1896 were based on a new design by E.R. Johnson. In 1897–8 Berliner spread his activities to England and Germany, setting up a European pressing plant in the telephone factory in Hanover, and in 1899 a Canadian company was formed. Various court cases over patents removed Berliner from direct running of the reconstructed companies, but he retained a major economic interest in E.R. Johnson's Victor Talking Machine Company. In later years Berliner became interested in aeronautics, in particular the autogiro principle. Applied acoustics was a continued interest, and a tile for controlling the acoustics of large halls was successfully developed in the 1920s.

  • 33 Curr, John

    [br]
    b. 1756 Kyo, near Lanchester, or in Greenside, near Ryton-on-Tyne, Durham, England
    d. 27 January 1823 Sheffield, England
    [br]
    English coal-mine manager and engineer, inventor of flanged, cast-iron plate rails.
    [br]
    The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.
    In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.
    Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.
    Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.

    b. 1889 USA
    d. 1 May 1970 Summit, New Jersey, USA
    [br]
    American engineer who made contributions to radio communications.
    [br]
    Hartley obtained his BA in 1909 from the University of Utah, then gained a Rhodes Scholarship to Oxford University, England. After obtaining a further BA and a BSc in 1912 and 1913, respectively, he returned to the USA and took a job with the Western Electric Laboratories of the Bell Telephone Company, where he was in charge of radio-receiver development. In 1915 he invented the Hartley oscillator, analogous to that invented by Colpitts. Subsequently he worked on carrier telephony at Western Electric and then at Bell Laboratories. There he concen-trated on information theory, building on the pioneering work of Nyquist, in 1926 publishing his law that related information capacity, frequency bandwidth and time. Forced to give up work in 1929 due to ill health, he returned to Bell in 1939 as a consultant on transmission problems. During the Second World War he worked on various projects, including the use of servo-mechanisms for radar and fire control, and finally retired in 1950.

  • 35 Joy, David

    [br]
    b. 3 March 1825 Leeds, England
    d. 14 March 1903 Hampstead, London, England
    [br]
    English mechanical engineer, designer of the locomotive Jenny Lind and of Joy's valve gear for steam engines.
    [br]
    By the mid-1840s Joy was Chief Draughtsman at E.B.Wilson's locomotive works at Leeds. During that period, attempts by engineers to design ever larger and more powerful locomotives were producing ungainly types, such as the long-boiler and the Cramp ton, which were to prove blind alleys in locomotive development. Joy rediscovered the proper route with his Jenny Lind 2–2–2, built in 1847. His locomotive had minimal overhang, with the firebox between the driving and trailing axles; the driving axle supported inside frames which stopped short at the firebox, allowing the latter to be wide, while leading and trailing wheels were held by outside plate frames which had a degree of elasticity. The boiler was low-pitched, the steam pressure high at 120 psi (8.4 kg/cm2). The result was a powerful locomotive which rode well and immediately became popular, a forerunner of many later designs. Joy subsequently had a varied career with successive railways and engineering firms. In the late 1850s he invented steam reversing gear for large, marine steam engines, a hydraulic organ blower and a pneumatic hammer. In 1879 he invented his radial valve gear for steam engines, which was adopted by F.W. Webb for the London \& North Western Railway's locomotives and was also much used in marine steam engines.

  • 36 Savery, Thomas

    [br]
    b. c. 1650 probably Shilston, near Modbury, Devonshire, England
    d. c. 15 May 1715 London, England
    [br]
    English inventor of a partially successful steam-driven pump for raising water.
    [br]
    Little is known of the early years of Savery's life and no trace has been found that he served in the Army, so the title "Captain" is thought to refer to some mining appointment, probably in the West of England. He may have been involved in the Glorious Revolution of 1688, for later he was well known to William of Orange. From 1705 to 1714 he was Treasurer for Sick and Wounded Seamen, and in 1714 he was appointed Surveyor of the Water Works at Hampton Court, a post he held until his death the following year. He was interested in mechanical devices; amongst his early contrivances was a clock.
    He was the most prolific inventor of his day, applying for seven patents, including one in 1649, for polishing plate glass which may have been used. His idea for 1697 for propelling ships with paddle-wheels driven by a capstan was a failure, although regarded highly by the King, and was published in his first book, Navigation Improved (1698). He tried to patent a new type of floating mill in 1707, and an idea in 1710 for baking sea coal or other fuel in an oven to make it clean and pure.
    His most famous invention, however, was the one patented in 1698 "for raising water by the impellent force of fire" that Savery said would drain mines or low-lying land, raise water to supply towns or houses, and provide a source of water for turning mills through a water-wheel. Basically it consisted of a receiver which was first filled with steam and then cooled to create a vacuum by having water poured over the outside. The water to be pumped was drawn into the receiver from a lower sump, and then high-pressure steam was readmitted to force the water up a pipe to a higher level. It was demonstrated to the King and the Royal Society and achieved some success, for a few were installed in the London area and a manufactory set up at Salisbury Court in London. He published a book, The Miner's Friend, about his engine in 1702, but although he made considerable improvements, due to excessive fuel consumption and materials which could not withstand the steam pressures involved, no engines were installed in mines as Savery had hoped. His patent was extended in 1699 until 1733 so that it covered the atmospheric engine of Thomas Newcomen who was forced to join Savery and his other partners to construct this much more practical engine.

  • 37 Sendzimir, Tadeusz

    SUBJECT AREA: Metallurgy
    [br]
    fl. twentieth century USA
    [br]
    American metallurgist, inventor of the planetary rolling mill.
    [br]
    The principle of the Sendzimir or planetary rolling mill was first conceived by an English engineer named Picken, but that did not lead to practical development. The principle was taken up independently in the USA by Sendzimir, who put forward his own ideas in 1948 and obtained a patent the same year. By 1952 he had reached agreements with Picken and other workers to license the construction of a plant completely under the control of Sendzimir and his associates. This type of rolling mill was developed primarily for the cold rolling of steel strip. Cold rolling requires higher pressures to be exerted by the rolls, which therefore must be harder than in hot rolling. In the Sendzimir mill the two hard work rolls are backed up by a cluster of heavier rolls of various sizes to prevent distortion of the work rolls. One advantage of this arrangement is that the work rolls can be quite small, so that they can be removed by hand when they need replacement. The Sendzimir mill is in wide use, particularly for rolling stainless steel. The first such mill was installed at Peugeot's in France in 1950, with two sets of planetary rolls for the hot rolling of 16 in. (41 cm) wide steel strip. The second was in the USA in 1951, and a third, larger one followed at Ductile Steels Ltd at Willenhall, Wolverhampton, England, in 1953.

  • 38 Stuart, Herbert Akroyd

    [br]
    b. 1864 Halifax, England
    d. 1927 Perth, Australia
    [br]
    English inventor of an oil internal-combustion engine.
    [br]
    Stuart's involvement with engines covered a period of less than ten years and was concerned with a means of vaporizing the heavier oils for use in the so-called oil engines. Leaving his native Yorkshire for Bletchley in Buckinghamshire, Stuart worked in his father's business, the Bletchley Iron and Tin Plate works. After finishing grammar school, he worked as an assistant in the Mechanical Engineering Department of the City and Guilds of London Technical College. He also formed a connection with the Finsbury Technical College, where he became acquainted with Professor William Robinson, a distinguished engineer eminent in the field of internal-combustion engines.
    Resuming work at Bletchley, Stuart carried out experiments with engines. His first patent was concerned with new methods of vaporizing the fuel, scavenging systems and improvement of speed control. Two further patents, in 1890, specified substantial improvements and formed the basis of later engine designs. In 1891 Stuart joined forces with R.Hornsby and Sons of Grantham, a firm founded in 1815 for the manufacture of machinery and steam engines. Hornsby acquired all rights to Stuart's engine patents, and their superior technical resources ensured substantial improvements to Stuart's early design. The Hornsby-Ackroyd engines, introduced in 1892, were highly successful and found wide acceptance, particularly in agriculture. With failing health, Stuart's interest in his engine work declined, and in 1899 he emigrated to Australia, where in 1903 he became a partner in importing gas engines and gas-producing plants. Following his death in 1927, under the terms of his will he was interred in England; sadly, he also requested that all papers and materials pertaining to his engines be destroyed.
