Maurice Lemaître (Maurice Édouard Jean Joseph Ghislain Lemaître; born Charleroi, 6 July 1898; died Etterbeek 25 December 1974) was a Belgian mechanical engineer who developed a steam locomotive exhaust system first used by the Nord-Belge railway company, a subsidiary of the French-owned Chemins de Fer du Nord. The Lemaître exhaust (''échappement Lemaître'') – which featured a blastpipe with five nozzles in a circular pattern exhausting up a large-diameter chimney, plus a variable-area nozzle exhausting up the centre – produced an efficiency gain of around 10%. The design was later improved by the Argentine engineer Livio Dante Porta, who devised the Lempor (a portmanteau In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed by combining the meanings, and parts of the sounds, of two or more words together.

Etterbeek
Etterbeek (; ) is one of the List of municipalities of the Brussels-Capital Region, 19 municipalities of the Brussels-Capital Region, Belgium. Located in the eastern part of the region, it is bordered by the municipalities of Auderghem, the City of Brussels, Ixelles, Schaerbeek, Woluwe-Saint-Lambert and Woluwe-Saint-Pierre. In common with all of Brussels' municipalities, it is legally Multilingualism, bilingual (French–Dutch). History Origins and etymology According to legend, Saint Gertrude of Nivelles, daughter of Pippin of Landen, founded a chapel there in the 8th century. A document by Otto I, Holy Roman Emperor, dated 966, mentions the church of ''Iatrebache''. The name ''Ietrebecca''—possibly from the Celtic languages, Celtic root ''ett'' meaning "rapid movement" and the Dutch word ''beek'' meaning "stream"—is found for the first time in a document dated 1127. The current spelling appears eleven years later in 1138, around which time a newer and larger church was bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belgians
Belgians ( ; ; ) are people identified with the Kingdom of Belgium, a federal state in Western Europe. As Belgium is a multinational state, this connection may be residential, legal, historical, or cultural rather than ethnic. The majority of Belgians, however, belong to two distinct linguistic groups or ''communities'' (; ) native to the country, i.e. its historical regions: Flemings in Flanders, who speak Dutch, West Flemish and Limburgish; and Walloons in Wallonia, who speak French or Walloon. There is also a substantial Belgian diaspora, which has settled primarily in the United States, Canada, France, and the Netherlands. Etymology The 1830 revolution led to the establishment of an independent country under a provisional government and a national congress. The name "Belgium" was adopted for the country, the word being derived from '' Gallia Belgica'', a Roman province in the northernmost part of Gaul that, before Roman invasion in 100 BC, was inhabi ...

Steam Locomotive Exhaust System
The steam locomotive exhaust system consists of those parts of a steam locomotive which together discharge exhaust steam from the cylinders in order to increase the draught through the fire. It usually consists of the blastpipe (or first stage nozzle), smokebox, and chimney, although later designs also include second and third stage nozzles. History The primacy of discovery of the effect of directing the exhaust steam up the chimney as a means of providing draft through the fire is the matter of some controversy, Ahrons (1927) devoting significant attention to this matter. The exhaust from the cylinders on the first steam locomotive – built by Richard Trevithick – was directed up the chimney, and he noted its effect on increasing the draft through the fire at the time. At Wylam, Timothy Hackworth also employed a blastpipe on his earliest locomotives, but it is not clear whether this was an independent discovery or a copy of Trevithick's design. Shortly after Hackworth, G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lemaître Exhaust
Lemaître, Lemaitre, Le Maitre, or ''variation'', is a French surname meaning "the master" – derived from the Latin word "magister". Notable people with the surname include: Lemaître * Anne Lemaître (born 1957) Belgian applied mathematician * Delphine Philippe-Lemaître, (1798–1863), French historian, archaeologist, botanist * Frédérick Lemaître (1800–1876), French actor and playwright * Georges Lemaître (1894–1966), Belgian Roman Catholic priest and astronomer, who formulated the "Big Bang" theory of cosmologic origin of the physical universe. ** Named for Georges Lemaître: *** Lemaître (crater), an impact crater on the Moon *** 1565 Lemaître, a minor planet *** the Friedmann–Lemaître–Robertson–Walker metric *** the Lemaître metric *** the Lemaître–Tolman metric *** Lemaitre (band), Norwegian indie electronic band *** Georges Lemaître ATV, an uncrewed spacecraft * Jules Lemaître (1853–1914), French critic and dramatist * Maurice Lemaître ...

Blastpipe
The blastpipe is part of the exhaust system of a steam locomotive that discharges exhaust steam from the cylinders into the smokebox beneath the chimney in order to increase the draught through the fire. History The primacy of discovery of the effect of directing the exhaust steam up the chimney as a means of providing draft through the fire is the matter of some controversy, Ahrons (1927) devoting significant attention to this matter. The exhaust from the cylinders on the first steam locomotive – built by Richard Trevithick – was directed up the chimney, and he noted its effect on increasing the draft through the fire at the time. At Wylam, Timothy Hackworth also employed a blastpipe on his earliest locomotives, but it is not clear whether this was an independent discovery or a copy of Trevithick's design. Shortly after Hackworth, George Stephenson also employed the same method, and again it is not clear whether that was an independent discovery or a copy of one of the ...

Livio Dante Porta
Livio Dante Porta (21 March 1922 – 10 June 2003) was an Argentine steam locomotive engineer. He is particularly remembered for his innovative modifications to existing locomotive systems in order to obtain better performance and energy efficiency, and reduced pollution. He developed the Kylpor and Lempor exhaust systems. The Lemprex was under development at the time of his death. Early years Porta was born in Paraná, Entre Ríos, and studied civil engineering, concluding his studies in 1946, at a time when steam was already giving way to diesel and electric locomotives in Europe and North America. Career Naturally, Porta's first projects were in Argentina. Taking the work of Andre Chapelon in France as his starting point, he set out to demonstrate that the steam locomotive was far from reaching its maximum potential. His first locomotive project in 1948 took the remains of a 4-6-2 converting it into a 4-cylinder compound 4-8-0 named 'Presidente Peron'/'Argentina ...

Lempor Ejector
The Lempor ejector is a steam locomotive exhaust system developed by noted Argentine locomotive engineer Livio Dante Porta. The ejector's name is a portmanteau of the names of Porta and Belgian locomotive engineer Maurice Lemaître. The Lempor ejector follows the principles of the de Laval nozzle. Operation In steam locomotives, draft Draft, the draft, or draught may refer to: Watercraft dimensions * Draft (hull), the distance from waterline to keel of a vessel * Draft (sail), degree of curvature in a sail * Air draft, distance from waterline to the highest point on a v ... is produced in the firebox by exhausting waste steam from the cylinders into the chimney via a nozzle or 'blast pipe' to create a vacuum in the smokebox. The Lempor ejector is a development of similar multiple orifice/nozzle ejectors which create either a stronger vacuum or the same vacuum more efficiently by having less 'back pressure' or resistance to the exhausting cylinder.

Lemprex Ejector
A Lemprex ejector is a type of steam locomotive exhaust system developed by noted Argentinian locomotive engineer Livio Dante Porta (d. 2003). The name is a stylization of LeMaitre Porta Exhaust. In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out the chimney. The Lemprex exhaust will deliver improved draughting capacity over traditional exhaust systems. However development is only at an early stage.
