  • 5 Taylor, David Watson

    SUBJECT AREA: Ports and shipping
    [br]
    b. 4 March 1864 Louisa County, Virginia, USA
    d. 29 July 1940 Washington, DC, USA
    [br]
    American hydrodynamicist and Rear Admiral in the United States Navy Construction Corps.
    [br]
    Taylor's first years were spent on a farm in Virginia, but at the age of 13 he went to RandolphMacon College, graduating in 1881, and from there to the US Naval Academy, Annapolis. He graduated at the head of his class, had some sea time, and then went to the Royal Naval College in Greenwich, England, where in 1888 he again came top of the class with the highest-ever marks of any student, British or overseas.
    On his return to the United States he held various posts as a constructor, ending this period at the Mare Island Navy Yard in California. In 1894 he was transferred to Washington, where he joined the Bureau of Construction and started to interest the Navy in ship model testing. Under his direction, the first ship model tank in the United States was built at Washington and for fourteen years operated under his control. The work of this establishment gave him the necessary information to write the highly acclaimed text The Speed and Power of Ships, which with revisions is still in use. By the outbreak of the First World War he was one of the world's most respected naval architects, and had been retained as a consultant by the British Government in the celebrated case of the collision between the White Star Liner Olympic and HMS Hawke.
    In December 1914 Taylor became a Rear-Admiral and was appointed Chief Constructor of the US Navy. His term of office was extremely stressful, with over 1,000 ships constructed for the war effort and with the work of the fledgling Bureau for Aeronautics also under his control. The problems were not over in 1918 as the Washington Treaty required drastic pruning of the Navy and a careful reshaping of the defence force.
    Admiral Taylor retired from active service at the beginning of 1923 but retained several consultancies in aeronautics, shipping and naval architecture. For many years he served as consultant to the ship-design company now known as Gibbs and Cox. Many honours came his way, but the most singular must be the perpetuation of his name in the David Taylor Medal, the highest award of the Society of Naval Architects and Marine Engineers in the United States. Similarly, the Navy named its ship test tank facility, which was opened in Maryland in 1937, the David W. Taylor Model Basin.

  • 7 Porter, Charles Talbot

    [br]
    b. 18 January 1826 Auburn, New York, USA
    d. 1910 USA
    [br]
    American inventor of a stone dressing machine, an improved centrifugal governor and a high-speed steam engine.
    [br]
    Porter graduated from Hamilton College, New York, in 1845, read law in his father's office, and in the autumn of 1847 was admitted to the Bar. He practised for six or seven years in Rochester, New York, and then in New York City. He was drawn into engineering when aged about 30, first through a client who claimed to have invented a revolutionary type of engine and offered Porter the rights to it as payment of a debt. Having lent more money, Porter saw neither the man nor the engine again. Porter followed this with a similar experience over a patent for a stone dressing machine, except this time the machine was built. It proved to be a failure, but Porter set about redesigning it and found that it was vastly improved when it ran faster. His improved machine went into production. It was while trying to get the steam engine that drove the stone dressing machine to run more smoothly that he made a discovery that formed the basis for his subsequent work.
    Porter took the ordinary Watt centrifugal governor and increased the speed by a factor of about ten; although he had to reduce the size of the weights, he gained a motion that was powerful. To make the device sufficiently responsive at the right speed, he balanced the centrifugal forces by a counterweight. This prevented the weights flying outwards until the optimum speed was reached, so that the steam valves remained fully open until that point and then the weights reacted more quickly to variations in speed. He took out a patent in 1858, and its importance was quickly recognized. At first he manufactured and sold the governors himself in a specially equipped factory, because this was the only way he felt he could get sufficient accuracy to ensure a perfect action. For marine use, the counterweight was replaced by a spring.
    Higher speed had brought the advantage of smoother running and so he thought that the same principles could be applied to the steam engine itself, but it was to take extensive design modifications over several years before his vision was realized. In the winter of 1860–1, J.F. Allen met Porter and sketched out his idea of a new type of steam inlet valve. Porter saw the potential of this for his high-speed engine and Allen took out patents for it in 1862. The valves were driven by a new valve gear designed by Pius Fink. Porter decided to display his engine at the International Exhibition in London in 1862, but it had to be assembled on site because the parts were finished in America only just in time to be shipped to meet the deadline. Running at 150 rpm, the engine caused a sensation, but as it was non-condensing there were few orders. Porter added condensing apparatus and, after the failure of Ormerod Grierson \& Co., entered into an agreement with Joseph Whitworth to build the engines. Four were exhibited at the 1867 Paris Exposition Universelle, but Whitworth and Porter fell out and in 1868 Porter returned to America.
    Porter established another factory to build his engine in America, but he ran into all sorts of difficulties, both mechanical and financial. Some engines were built, and serious production was started c. 1874, but again there were further problems and Porter had to leave his firm. High-speed engines based on his designs continued to be made until after 1907 by the Southwark Foundry and Machine Company, Philadelphia, so Porter's ideas were proved viable and led to many other high-speed designs.

  • 8 Edison, Thomas Alva

    [br]
    b. 11 February 1847 Milan, Ohio, USA
    d. 18 October 1931 Glenmont
    [br]
    American inventor and pioneer electrical developer.
    [br]
    He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.
    At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.
    Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.
    He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.
    Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.
    Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.
    Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.
    In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.
    On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.
    Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.
    In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.
    In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.
    In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.
    In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.
    In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.

    SUBJECT AREA: Electricity
    [br]
    b. 27 July 1862 Neisse, Upper Silesia (now Nysa, Poland)
    d. 18 January 1921 Berthelsdorf, Silesia
    [br]
    German electrical engineer, inventor of a transformer for electromotors.
    [br]
    Ilgner graduated from the Gewerbeakademie (the forerunner of the Technical University) in Berlin. As the representative of an electric manufacturing company in Breslau (now Wroclaw, Poland) from 1897, he was confronted with the fact that there were no appropriate drives for hoisting-engines or rolling-plants in steelworks. Two problems prevented the use of high-capacity electric motors in the mining as well as in the iron and steel industry: the reactions of the motors on the circuit at the peak point of stress concentration; and the complicated handling of the control system which raised the risks regarding safety. Having previously been head of the department of electrical power transmission in Hannover, he was concerned with the development of low-speed direct-current motors powered by gas engines.
    It was Harry Ward Leonard's switchgear for direct-current motors (USA, 1891) that permitted sudden and exact changes in the speed and direction of rotation without causing power loss, as demonstrated in the driving of a rolling sidewalk at the Paris World Fair of 1900. Ilgner connected this switchgear to a large and heavy flywheel which accumulated the kinetic energy from the circuit in order to compensate shock loads. With this combination, electric motors did not need special circuits, which were still weak, because they were working continuously and were regulated individually, so that they could be used for driving hoisting-engines in mines, rolling-plants in steelworks or machinery for producing tools and paper. Ilgner thus made a notable advance in the general progress of electrification.
    His transformer for hoisting-engines was patented in 1901 and was commercially used inter alia by Siemens \& Halske of Berlin. Their first electrical hoisting-engine for the Zollern II/IV mine in Dortmund gained international reputation at the Düsseldorf exhibition of 1902, and is still preserved in situ in the original machine hall of the mine, which is now a national monument in Germany. Ilgner thereafter worked with several companies to pursue his conception, became a consulting engineer in Vienna and Breslau and had a government post after the First World War in Brussels and Berlin until he retired for health reasons in 1919.

    [br]
    Laithwaite's education at Kirkham Grammar School and Regent Street Polytechnic, London, was followed by service in the Royal Air Force. After entering Manchester University in 1946 and graduating in 1949, he joined the university staff and became Secretary to the Inaugural Conference of the Ferranti Mark I computer. In 1964 he moved to Imperial College of Science and Technology, London, and became Professor of Heavy Electrical Engineering. From 1967 to 1976 he also held the post of External Professor of Applied Electricity at the Royal Institution. Research into the use of linear induction motors as shuttle drives in weaving looms was followed by investigations into their application to conveyors in industrial processes and as high-speed propulsion units for railway vehicles. With considerable involvement in a tracked hovercraft project in the 1960s and 1970s, he proposed the concept of transverse flux and the magnetic river high-speed linear induction machine. Linear motors and electromagnetic levitation have been applied to high-speed propulsion in the United States, France and Japan.
    Laithwaite has written five books and over one hundred papers on the subjects of linear motors and electromagnetic levitation. Two series of Christmas lectures were presented by him at the Royal Institution.

    [br]
    b. 1829 England
    d. 2 October 1900 New York (?), USA
    [br]
    English inventor of the Allen valve used on his pioneering high-speed engines.
    [br]
    Allen was taken to the United States from England when he was 12 years old. He became an engineer on the Curlew, a freight boat running between New York and Providence. A defect which caused the engine to race in rough weather led Allen to invent a new valve gear, but he found it could not be fitted to the Corliss engine. In 1856 he patented an improved form of valve and operating gear to reduce back-pressure in the cylinder, which was in fact the reverse of what happened in his later engines. In 1860 he repaired the engines of a New York felt-hat manufacturer, Henry Burr, and that winter he was introduced to Charles Porter. Porter realized the potential of Allen's valves for his idea of a high-speed engine, and the Porter-Allen engine became the pioneer of high-speed designs.
    Porter persuaded Allen to patent his new valves and two patents were obtained in 1862. These valves could be driven positively and yet the travel of the inlet could be varied to give the maximum expansion at different cut-offs. Also, the valves allowed an exceptionally good flow of steam. While Porter went to England and tried to interest manufacturers there, Allen remained in America and continued work on the engine. Within a few years he invented an inclined watertube boiler, but he seemed incapable of furthering his inventions once they had been placed on the market. Although he mortgaged his own house in order to help finance the factory for building the steam engine, in the early 1870s he left Porter and built a workshop of his own at Mott Haven. There he invented important systems for riveting by pneumatic machines through both percussion and pressure which led into the production of air compressors and riveting machines.

    Mavor came from a distinguished Scottish family with connections in medicine, industry and the arts. On completion of his education at Glasgow University, he joined R.J.Crompton \& Co.; then in 1883, along with William C.Muir, he established the Glasgow firm which later became well known as Mavor and Coulson. It pioneered the supply of electricity to public undertakings and equipped the first two generating stations in Scotland. Mavor and his fellow directors appreciated the potential demand by industry in Glasgow for electricity. Two industries were especially well served; first, the coal-mines, where electric lighting and power transformed efficiency and safety beyond recognition; and second, marine engineering. Here Mavor recognized the importance of the variable-speed motor in working with marine propellers which have a tighter range of efficient working speeds. In 1911 he built a 50 ft (15 m) motor launch, appropriately named Electric Arc, at Dumbarton and fitted it with an alternating-current motor driven by a petrol engine and dynamo. Within two years British shipyards were building electrically powered ships, and by the beginning of the First World War the United States Navy had a 20,000-ton collier with this new form of propulsion.

  • 13 Meikle, Andrew

    [br]
    b. 1719 Scotland
    d. 27 November 1811
    [br]
    Scottish millwright and inventor of the threshing machine.
    [br]
    The son of the millwright James Meikle, who is credited with the introduction of the winnowing machine into Britain, Andrew Meikle followed in his father's footsteps. His inventive inclinations were first turned to developing his father's idea, and together with his own son George he built and patented a double-fan winnowing machine.
    However, in the history of agricultural development Andrew Meikle is most famous for his invention of the threshing machine, patented in 1784. He had been presented with a model of a threshing mill designed by a Mr Ilderton of Northumberland, but after failing to make a full-scale machine work, he developed the concept further. He eventually built the first working threshing machine for a farmer called Stein at Kilbagio. The patent revolutionized farming practice because it displaced the back-breaking and soul-destroying labour of flailing the grain from the straw. The invention was of great value in Scotland and in northern England when the land was becoming underpopulated as a result of heavy industrialization, but it was bitterly opposed in the south of England until well into the nineteenth century. Although the introduction of the threshing machine led to the "Captain Swing" riots of the 1830s, in opposition to it, it shortly became universal.
    Meikle's provisional patent in 1785 was a natural progression of earlier attempts by other millwrights to produce such a machine. The published patent is based on power provided by a horse engine, but these threshing machines were often driven by water-wheels or even by windmills. The corn stalks were introduced into the machine where they were fed between cast-iron rollers moving quite fast against each other to beat the grain out of the ears. The power source, whether animal, water or wind, had to cause the rollers to rotate at high speed to knock the grain out of the ears. While Meikle's machine was at first designed as a fixed barn machine powered by a water-wheel or by a horse wheel, later threshing machines became mobile and were part of the rig of an agricultural contractor.
    In 1788 Meikle was awarded a patent for the invention of shuttered sails for windmills. This patent is part of the general description of the threshing machine, and whilst it was a practical application, it was superseded by the work of Thomas Cubitt.
    At the turn of the century Meikle became a manufacturer of threshing machines, building appliances that combined the threshing and winnowing principles as well as the reciprocating "straw walkers" found in subsequent threshing machines and in conventional combine harvesters to the present day. However, he made little financial gain from his invention, and a public subscription organized by the President of the Board of Agriculture, Sir John Sinclair, raised £1,500 to support him towards the end of his life.

    d. 27 February 1874 St Petersburg, Russia
    [br]
    German scientist who developed one of the first practical electric motors.
    [br]
    After studying architecture at Göttingen University, Jacobi turned his attention to physics and chemistry. In 1835 he was appointed a professor of civil engineering at the University of Dorpat (which later assumed the Estonian name of Tartu). Later, moving to St Petersburg, he became a member of the Imperial Academy of Sciences and commenced research on electricity and its practical applications. In December 1834 Jacobi presented a paper to the Academy of Sciences in Paris in which he stated that he had obtained rotation by electromagnetic methods in May of that year. Tsar Nicholas of Russia gave him a grant to prove that his electric motor had a practical application. Jacobi had a boat constructed that measured 28 ft in length and was propelled by paddles connected to an electric motor of his own design. Powered by Grove cells, it carried about fourteen passengers at a speed of almost 3 mph (5 km/h) on the River Neva. The weight of and possibly the fumes from the batteries contributed to the abandonment of the project. In 1839 Jacobi introduced electrotyping, i.e. the reproduction of forms by electrodeposition, which was one of the first commercial applications of electricity. In 1840 he reported the results of his investigations into the power of the electromagnet as a function of various parameters to the British Association.

    English inventor of one of the first circular, power-driven knitting machines.
    [br]
    The family firm of Paget's of Loughborough was of long standing in hosiery manufacture. They were well aware of the importance of modernizing their factory with the latest improvements in machinery, as well as developing their own inventions. They discovered Marc Brunel's circular knitting machine c.1844 and constructed many on that principle, with modifications that performed very well. Arthur Paget took out three patents. The first, was in 1857, was for making the machine self-acting so that it could be driven by power. In his patent of 1859 he introduced modifications on the earlier patent, and his third patent, in 1860, described further alterations. These machines produced excellent work with speed and accuracy.

    [br]
    b. 25 May 1847 Dumbarton, Scotland
    d. 17 March 1887 Buenos Aires, Argentina
    [br]
    Scottish naval architect and partner in the leading British scientific shipbuilding company.
    [br]
    From 1844 until 1962, the Clyde shipyard of William Denny and Brothers, Dumbarton, produced over 1,500 ships, trained innumerable students of all nationalities in shipbuilding and marine engineering, and for the seventy-plus years of their existence were accepted worldwide as the leaders in the application of science to ship design and construction. Until the closure of the yard members of the Denny family were among the partners and later directors of the firm: they included men as distinguished as Dr Peter Denny (1821(?)–95), Sir Archibald Denny (1860–1936) and Sir Maurice Denny (1886– 1955), the main collaborator in the design of the Denny-Brown ship stabilizer.
    One of the most influential of this shipbuilding family was William Denny, now referred to as William 3! His early education was at Dumbarton, then on Jersey and finally at the Royal High School, Edinburgh, before he commenced an apprenticeship at his father's shipyard. From the outset he not only showed great aptitude for learning and hard work but also displayed an ability to create good relationships with all he came into contact with. At the early age of 21 he was admitted a partner of the shipbuilding business of William Denny and Brothers, and some years later also of the associated engineering firm of Denny \& Co. His deep-felt interest in what is now known as industrial relations led him in 1871 to set up a piecework system of payment in the shipyard. In this he was helped by the Yard Manager, Richard Ramage, who later was to found the Leith shipyard, which produced the world's most elegant steam yachts. This research was published later as a pamphlet called The Worth of Wages, an unusual and forward-looking action for the 1860s, when Denny maintained that an absentee employer should earn as much contempt and disapproval as an absentee landlord! In 1880 he initiated an awards scheme for all company employees, with grants and awards for inventions and production improvements. William Denny was not slow to impose new methods and to research naval architecture, a special interest being progressive ship trials with a view to predicting effective horsepower. In time this led to his proposal to the partners to build a ship model testing tank beside the Dumbarton shipyard; this scheme was completed in 1883 and was to the third in the world (after the Admiralty tank at Torquay, managed by William Froude and the Royal Netherlands Navy facility at Amsterdam, under B.J. Tideman. In 1876 the Denny Shipyard started work with mild-quality shipbuilding steel on hulls for the Irrawaddy Flotilla Company, and in 1879 the world's first two ships of any size using this weight-saving material were produced: they were the Rotomahana for the Union Steamship Company of New Zealand and the Buenos Ayrean for the Allan Line of Glasgow. On the naval-architecture side he was involved in Denny's proposals for standard cross curves of stability for all ships, which had far-reaching effects and are now accepted worldwide. He served on the committee working on improvements to the Load Line regulations and many other similar public bodies. After a severe bout of typhoid and an almost unacceptable burden of work, he left the United Kingdom for South America in June 1886 to attend to business with La Platense Flotilla Company, an associate company of William Denny and Brothers. In March the following year, while in Buenos Aires, he died by his own hand, a death that caused great and genuine sadness in the West of Scotland and elsewhere.

    d. 27 October 1972 Isle of Wight (?), England
    [br]
    English yacht designer.
    [br]
    Coming from a family that had originated in East Anglia, his first name was that of an early British king and was to typify his unusual and refreshing zest for life. Fox commenced his professional career as an apprentice with the flying boat and high-speed craft builders Messrs S.E.Saunders, and shortly after the outbreak of the First World War he was conscripted into the Royal Naval Air Service. In 1920 he made his first transatlantic crossing under sail, a much greater adventure then than now, and returned to the United Kingdom as deck-hand on a ship bound for Liverpool. He was to make the crossing under sail twice more. Shortly after his marriage in 1925, he purchased the old Floating Bridge at Cowes and converted it to living accommodation, workshops and drawing offices. By the 1930s his life's work was in full swing, with designs coming off his drawing board for some of the most outstanding mass-produced craft ever built, as well as for some remarkable one-off yachts. His experimentation with every kind of sailing craft, and even with the Eskimo kayak, gave him the knowledge and experience that made his name known worldwide. During the Second World War he designed and produced the world's first airborne parachuted lifeboat. Despite what could be described as a robust lifestyle, coupled with interests in music, art and horseriding, Fox continued to produce great designs and in the late 1940s he introduced the Firefly, followed by the beautiful Flying Fifteen class of racing keel boats. One of his most unusual vessels was Britannia, the 24 ft (7.3 m) waterline craft that John Fairfax was to row across the Atlantic. Later came Britannia II, which Fairfax took across the Pacific!

    [br]
    b. 9 May 1845 Orsa, Sweden
    d. 2 February 1913 Stockholm, Sweden
    [br]
    Swedish inventor of an advanced cream separator and a steam turbine.
    [br]
    Gustaf de Laval was educated at the Stockholm Technical Institute and Uppsala University. He proved to have an unfailing vigour and variety in his inventive talent, for his interests ranged from electric lighting and electrometallurgy to aerodynamics. In the 1890s he employed over one hundred engineers to develop his inventions, but he was best known for two: the cream separator and a steam turbine. In 1877 he invented the high-speed centrifugal cream separator, which was probably the greatest advance in butter-making up to that time. By 1880 the separators were being successfully marketed all over the world, for they were quickly adopted in larger dairies where they effected enormous savings in labour and space. He followed this with various devices for the dairy industry, including a vacuum milking machine perfected in 1913. In c. 1882, de Laval invented a turbine on the principle of Hero's engine, but he quickly turned his attention to the impulse type, which was like Branca's, with a jet of steam impinging on a set of blades around the periphery of a wheel. He applied for a British patent in 1889. The steam was expanded in a single stage from the initial to the final pressure: to secure economy with the steam issuing at high velocity, the blades also had to rotate at high velocity. An early 5 hp (3.7 kW) turbine rotated at 30,000 rpm, so reduction gearing had to be introduced. Production started in Sweden in 1893 and in other countries at about the same time. In 1892 de Laval proposed employing one of his turbines of 15 hp (11 kW) in an experimental launch, but there is no evidence that it was ever actually installed in a vessel. However, his turbines were popular for powering electric generating sets for lighting textile mills and ships, and by 1900 were available in sizes up to 300 bhp (224 kW).

    b. 10 May 1891 Hartlepool, England
    d. 18 December 1982 Belfast (?), Northern Ireland
    [br]
    English marine engineer and exponent of the slow-speed diesel engine.
    [br]
    Pounder served an apprenticeship with Richardsons Westgarth, marine engineers in north east England. Shortly after, he moved to Harland \& Wolff of Belfast and there fulfilled his life's work. He rose to the rank of Director but is remembered for his outstanding leadership in producing the most advanced steam and diesel machinery installations of their time. Harland \& Wolff were the main licensees for the Burmeister \& Wain marine diesel system, and the Copenhagen company made most of the decisions on design; however, Pounder often found himself in the hot seat and once had the responsibility of concurring with the shipyard's decision to build three Atlantic liners with the largest diesel engines in the world, well beyond the accepted safe levels of extrapolation. With this, Belfast secured worldwide recognition as builders of diesel-driven liners. During the German occupation of Denmark (1940–5), the engineering department at Belfast worked on its own and through systematic research and experimentation built up a database of information that was invaluable in the postwar years.
    Pounder was instrumental in the development of airless injection diesel fuel pumps. He was a stalwart supporter of all research and development, and while at Belfast was involved in the building of twelve hundred power units. While in his twenties, Pounder began a literary career which continued for sixty years. The bulk of his books and papers were on engineering and arguably the best known is his work on marine diesel engines, which ran to many editions. He was Chairman of Pametrada, the marine engineering research council of Great Britain, and later of the machinery committee of the British Ship Research Association. He regarded good relations within the industry as a matter of paramount importance.

    [br]
    b. 30 July 1940
    [br]
    English electronic engineer and inventor.
    [br]
    The son of G.W.C.Sinclair, a machine tool engineer, the young Sinclair's education was disrupted by the failure of his father's business. Aged 12 he left Boxgrove preparatory school and went through twelve more schools before leaving St George's School, Weybridge, at the age of 17. His first job was as an editorial assistant on a hobbyist's magazine, Practical Wireless, and his next as an editor at Bernard Books, writing a series of technical manuals. In 1961 he registered Sinclair Radionics and in the following year announced its first product, a micro-amplifier. This was the first of a series of miniaturized radio products that he put on the market while retaining his editorial job. In 1972 he launched the Sinclair Executive calculator, selling originally at £79.95 but later at £24.95. In 1976, the Black Watch, an electronic watch with digital light-emitting diode (LED) display, was marketed, to be followed by the TV1A, a miniature television with a 2 in. (5 cm) monochrome screen. During the latter part of this period, Sinclair Radionics was supported by investment from the UK National Enterprise Board, who appointed an outside managing director; after making a considerable loss, they closed the company in 1979. However, Sinclair Electronics had already been set up and started to market the UK's first cheap computer kit, the MK 14, which was followed by the ZX 80 and later the ZX 81. Price was kept at a minimum by the extensive use of existing components, though this was a restriction on performance. The small memory was enhanced from one kilobyte to seventeen kilobytes with the addition of a separate memory unit. In January 1985 Sinclair produced the Sinclair C5, a small three-wheeled vehicle driven by a washing-machine engine, intended as a revolutionary new form of personal transport; perceived as unsafe and impractical, it did not prove popular, and the failure of this venture resulted in a contraction of Sinclair's business activities. Later in 1985, a rival electronics company, Amstrad, paid £35,000,000 for all rights to existing Sinclair computer products.
    In March 1992, the irrepressible Sinclair launched his latest brainchild, the Zike electric bicycle; a price of £499 was forecast. This machine, powered by an electric motor but with pedal assistance, had a top speed of 19 km/h (12 mph) and, on full power, would run for up to one hour. Its lightweight nickel-cadmium battery could be recharged either by a generator or by free-wheeling. Although more practical than the C5, it did not bring Sinclair success on the scale of his earlier micro-electronic products.
