5 Branca, Giovanni de
SUBJECT AREA: Steam and internal combustion engines[br]b. 1571 Italyd. 1640 Italy[br]Italian architect who proposed what has been suggested as an early turbine, using a jet of steam to turn a wheel.[br]Branca practised architecture at Loretto. In 1629 he published Le Machine: volume nuovo et di molto artificio, in which he described various mechanisms. One was the application of rolls for working copper, lead or the precious metals gold and silver. The rolls were powered by a form of smokejack with the gases from the fire passing up a long tube forming a chimney which, through gearing, turned the rolls. Another device used a jet of steam from a boiler issuing from a mouthpiece shaped like the head of a person to impinge upon blades around the circumference of a horizontal wheel, connected through triple reduction gearing to drop stamps, for pounding drugs. This was a form of impulse turbine and has been claimed as the first machine worked by steam to do a particular operation since Heron's temple doors.[br]Further ReadingH.W.Dickinson, 1938, A Short History of the Steam Engine, Cambridge University Press (includes a description and picture of the turbine).C.Singer (ed.), 1957, A History of Technology, Vols III and IV, Oxford University Press (provides notes on Branca).RLH -

13 Keil, Alfredo
(1854-1907)Portuguese composer, musician, and painter of German descent who wrote the music for [I]A[/I] Portuguesa, the official national anthem of Portugal since 1911. Kiel began his studies in Germany, where he won bronze and silver medals for his work. He also showed his work in Rio de Janeiro, Brazil. In 1890, he opened an atelier on the Avenida da Liberdade, Lisbon, where he presented his seascapes, landscapes, and portraits. These works sold well, and some were even acquired by King Luís I for the royal art collection: A Saída da Igreja, A Primavera, Marinha, and Pôr-do-Sol.Having learned to play the piano, Keil began to study music with Hungarian pianist Oscar de le Cinne. Professor Ernesto Vieira taught him instrumentation and harmonization. Keil's first musical works were Aurora, Teus Olhos Negros, and Roses, Pompons e Romança. These were followed by Morenita, Souvenir de Vienne, and Carnaval. Well received, these works encouraged Keil to try his hand at opera. In 1882, he presented Suzana, a comic opera in one act. This was followed by other musical works, such as Recueil, melodies for the piano; Pátria, a work for piano and singer; Orientais, a symphony with chorus and solos; and D. Branca, an opera in four acts with a libretto taken from the poem by Almeida Garrett of the same title.D. Branca, presented in 1888, was wildly popular, which inspired Keil to write more operas: Irene (1893), and Serrana (1902). In 1902, he wrote the Hino do Infante D. Henriques for a festival marking the birthday of Prince Henry of Aviz (Prince Henry the Navigator), which was played by four military bands and sung by massed choruses. Additional patriotic music included, in 1895, a march titled Marcha de Gualdim Pais and A Portuguesa, with words by Lopes de Mendonça, which became the Portuguese national anthem in 1911. -

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.
