Louis Seguin
Seguin & Co. was a company based near Lyon, France. The company was involved in several business activities, the first of which was textiles but it was best known for having developed the first suspension bridges in Continental Europe and France's first commercial railway company, the Saint-Étienne–Lyon railway. Philanthropy The family, led by brothers Camille and Marc, gave its railway assets to the people of France, fearing that it could turn into a monopoly and not serve the greater public good. Marc Seguin The best known member of Seguin & Co. was French inventor Marc Seguin, father of the tubular steam-engine boiler and the suspension bridge system in continental Europe. Louis Seguin One notable offshoot of Seguin & Co. is Gnome et Rhône Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by v ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Europe
Continental Europe or mainland Europe is the contiguous continent of Europe, excluding its surrounding islands. It can also be referred to ambiguously as the European continent, – which can conversely mean the whole of Europe – and, by some, simply as the Continent. When Eurasia is regarded as a single continent, Europe is treated as a subcontinent, and called as European subcontinent. The old notion of Europe as a cultural term was centred on core Europe (''Kerneuropa''), the continental territory of the historical Carolingian Empire, corresponding to modern France, Italy, German-speaking Europe and the Benelux states (historical Austrasia). This historical core of "Carolingian Europe" was consciously invoked in the 1950s as the historical ethno-cultural basis for the prospective European integration (see also Multi-speed Europe). Usage The most common definition of Mainland Europe excludes these continental islands: the Greek Islands, Cyprus, Malta, Sicily, Sa ...

Saint-Étienne–Lyon Railway
The Saint-Étienne to Lyon line is a railway linking Saint-Étienne to Lyon. The line was built between 1828 and 1833 by Camille Seguin and Marc Seguin at a cost of 14,500,000 FRF. History Construction Construction began in September 1826. Marc Seguin was chief engineer, chief of estates, maintenance and rolling stock at the same time. Despite all the natural obstacles he encountered, Seguin drew up the plans for line, 56 km in length, with a slow descent towards Lyon. The first part of the line, between Saint-Étienne and Rive-de-Gier was laid at a constant descent of 1.2 to 1.4%. The following section, running along the Gier valley down to Givors, on the Rhône, was less inclined, with a slope of 0.65%. The last section of the line, to Lyon, was built virtually level. Technical data To avoid difficulties in acquiring land, with no laws concerning compulsory purchase at the time, Seguin built several bridges and tunnels. Between 1827 and 1830 he dug the firs ...

Gnome Et Rhône
Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by various licensees. These engines powered the majority of aircraft in the first half of the war, both Allied designs as well as German examples produced by Motorenfabrik Oberursel. In the post-war era they started a new design series originally based on the Bristol Jupiter, but evolving into the excellent twin-row, 1,000 hp-class (750 kW) Gnome-Rhône 14K ''Mistral Major'' radial, which was likewise licensed and used around the world during World War II. They were a major supplier of engines to the German ''Luftwaffe'', producing both their own designs as well as German ones under licence. Their factories were the target of highly accurate bombing, knocking them out of the war. The company was nationalized as a part of Snecma in 1949, but ...
