Rue De L'Avenir
The Rue de l'Avenir () was an electric moving walkway installed at the 1900 Exposition Universelle in Paris. It ran along the edge of the Exposition site, from the Esplanade of Les Invalides to the Champ de Mars, passing through nine stations along the way, where passengers could board. It was designed by architect Joseph Lyman Silsbee and engineer Max E. Schmidt, designers of ''The Great Wharf Moving Sidewalk'' installed at the 1893 World's Fair in Chicago, the first-ever moving walkway. Features The moving sidewalk was a very popular and useful attraction, given the large size of the Exposition. It consisted of a fixed platform and two mobile platforms, on a viaduct above the ground level, that covered a loop around the exhibition site with nine stations. The passengers stepped from the platform onto an access sidewalk wide traveling at , then onto a faster sidewalk wide moving at . The sidewalks had posts with handles which passengers could hold onto, or they could walk. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelligenc ...

French Franc
The franc (, ; sign: F or Fr), also commonly distinguished as the (FF), was a currency of France. Between 1360 and 1641, it was the name of coins worth 1 livre tournois and it remained in common parlance as a term for this amount of money. It was reintroduced (in decimal form) in 1795. After two centuries of inflation, it was redenominated in 1960, with each (NF) being worth 100 old francs. The NF designation was continued for a few years before the currency returned to being simply the franc. Many French residents, though, continued to quote prices of especially expensive items in terms of the old franc (equivalent to the new centime), up to and even after the introduction of the euro (for coins and banknotes) in 2002. The French franc was a commonly held international reserve currency of reference in the 19th and 20th centuries. Between 1998 and 2002, the conversion of francs to euros was carried out at a rate of 6.55957 francs to 1 euro. History The French Franc tr ...

Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pont Des Invalides
The Pont des Invalides is the lowest bridge traversing the Seine in Paris. History The story of this bridge started in 1821, when engineer Claude Navier conceived a technologically revolutionary bridge that crossed the Seine in one single reach without any point of support in between. The proposed suspension bridge, the construction of which started in 1824, was meant to be erected opposite to the Hotel des Invalides on the site of the current Pont Alexandre III. Navier failed to leave a safety margin on top of his calculations, and the contract to build the bridge was unusually rigid. After Navier's plan had been approved by the private investment company, the contractor could not make changes without approval, and there was no authorization to suggest improvements. The bridge became unsafe after cracking of the anchorages due to natural settling and additional movement after a water main break near the buttresses. The bridge had to be dismantled, and Navier was chastised by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Decauville
Decauville () was a manufacturing company which was founded by Paul Decauville (1846–1922), a French pioneer in industrial railways. Decauville's major innovation was the use of ready-made sections of light, narrow gauge track fastened to steel sleepers; this track was portable and could be disassembled and transported very easily. The first Decauville railway used gauge; Decauville later refined his invention and switched to and gauge. History Origins In 1853 Paul Decauville's father, Amand, created a boilermaking workshop on the family farm in order to set up distilleries on the farms to the east of Paris. In 1864, Amand asked his eldest son, Paul, to come and help him following health problems. Very quickly, the latter seeks to improve the functioning of the estate. Very developed under the Second Empire in the northern half of France, the production of sugar beet and its refining into sugar, is linked to that of alcoholic products such as fuel. Amand will therefore en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quai D'Orsay
The Quai d'Orsay ( , ) is a quay in the 7th arrondissement of Paris. It is part of the left bank of the Seine opposite the Place de la Concorde. The Quai becomes the Quai Anatole-France east of the Palais Bourbon, and the Quai Branly west of the Pont de l'Alma. History The Quai (rue du Bac) has historically played an important role in French art as a location to which many artists came to paint along the banks of the river Seine. Construction of the wharf proceeded slowly. The French Ministry of Foreign Affairs is located on the Quai d'Orsay, between the Esplanade des Invalides and the National Assembly at the Palais Bourbon, and thus the ministry is often called the Quai d'Orsay by metonymy. The building containing the Ministry of Foreign Affairs was built between 1844 and 1855 by Jacques Lacornée. The statues of the facade were created by the sculptor Henri de Triqueti (1870). The Treaty of Versailles (1919) was negotiated and written at the Ministry of Foreign Affairs. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circle Route
A circle route (also circumference, loop, ring route, ring line or orbital line) is a public transport route following a path approximating a circle or at least a closed curve. The expression "circle route" may refer in particular to: * a route orbiting a central point, commonly the central business district (CBD) in a city or large town * a route running in approximately a circular path from a point near the centre of a city or town out to a peripheral point and back again * a feeder route running from an interchange station around a neighbourhood or suburb in approximately a circle Typically, a circle route will connect at several locations with one or more cross-city routes or radial routes offering services in a straighter line into or out of a city or town centre. When a circle route orbits a central business district in a large arc, it will often provide transverse (or lateral) links between suburbs or satellites, either on its own or in combination with other routes. ...

Moving Walkway
A moving walkway, also known as an autowalk, moving pavement, moving sidewalk, people-mover, travolator, or travelator, is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction. History The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois, in the United States as ''The Great Wharf Moving Sidewalk'' and was designed by architect Joseph Lyman Silsbee. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the 1900 Exposition Universelle in Paris as the '' Rue de l'Avenir''. The walkway consisted of three elevated platforms, the first was stationary, the second m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
