19 Ferranti, Sebastian Ziani de
[br]b. 9 April 1864 Liverpool, Englandd. 13 January 1930 Zurich, Switzerland[br]English manufacturing engineer and inventor, a pioneer and early advocate of high-voltage alternating-current electric-power systems.[br]Ferranti, who had taken an interest in electrical and mechanical devices from an early age, was educated at St Augustine's College in Ramsgate and for a short time attended evening classes at University College, London. Rather than pursue an academic career, Ferranti, who had intense practical interests, found employment in 1881 with the Siemens Company (see Werner von Siemens) in their experimental department. There he had the opportunity to superintend the installation of electric-lighting plants in various parts of the country. Becoming acquainted with Alfred Thomson, an engineer, Ferranti entered into a short-lived partnership with him to manufacture the Ferranti alternator. This generator, with a unique zig-zag armature, had an efficiency exceeding that of all its rivals. Finding that Sir William Thomson had invented a similar machine, Ferranti formed a company with him to combine the inventions and produce the Ferranti- Thomson machine. For this the Hammond Electric Light and Power Company obtained the sole selling rights.In 1885 the Grosvenor Gallery Electricity Supply Corporation was having serious problems with its Gaulard and Gibbs series distribution system. Ferranti, when consulted, reviewed the design and recommended transformers connected across constant-potential mains. In the following year, at the age of 22, he was appointed Engineer to the company and introduced the pattern of electricity supply that was eventually adopted universally. Ambitious plans by Ferranti for London envisaged the location of a generating station of unprecedented size at Deptford, about eight miles (13 km) from the city, a departure from the previous practice of placing stations within the area to be supplied. For this venture the London Electricity Supply Corporation was formed. Ferranti's bold decision to bring the supply from Deptford at the hitherto unheard-of pressure of 10,000 volts required him to design suitable cables, transformers and generators. Ferranti planned generators with 10,000 hp (7,460 kW)engines, but these were abandoned at an advanced stage of construction. Financial difficulties were caused in part when a Board of Trade enquiry in 1889 reduced the area that the company was able to supply. In spite of this adverse situation the enterprise continued on a reduced scale. Leaving the London Electricity Supply Corporation in 1892, Ferranti again started his own business, manufacturing electrical plant. He conceived the use of wax-impregnated paper-insulated cables for high voltages, which formed a landmark in the history of cable development. This method of flexible-cable manufacture was used almost exclusively until synthetic materials became available. In 1892 Ferranti obtained a patent which set out the advantages to be gained by adopting sector-shaped conductors in multi-core cables. This was to be fundamental to the future design and development of such cables.A total of 176 patents were taken out by S.Z. de Ferranti. His varied and numerous inventions included a successful mercury-motor energy meter and improvements to textile-yarn produc-tion. A transmission-line phenomenon where the open-circuit voltage at the receiving end of a long line is greater than the sending voltage was named the Ferranti Effect after him.[br]Principal Honours and DistinctionsFRS 1927.

20 Laval, Carl Gustaf Patrik de
SUBJECT AREA: Agricultural and food technology, Electricity, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 9 May 1845 Orsa, Swedend. 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).[br]Bibliography1889, British patent no. 7,143 (steam turbine).Further ReadingT.Althin, 1943, Life of de Laval, Stockholm (a full biography).T.I.Williams (ed.), 1969, A Biographical Dictionary of Scientists, London: A. \& C.
