Emile Lamm
Emile Lamm (24 November 1834 – 12 July 1873, in New Orleans) was a French-born American inventor and dentist. Lamm was born in Aÿ, France, but moved to Louisiana in 1848 at the age of 14. He patented various improvements in techniques of gold dental fillings, and developed a number of innovative designs for street railways. These later were inspired by wishes to improve the Streetcars in New Orleans, as there was a desire for faster and more powerful propulsion than horsecars could provide, while steam locomotives created noise, smoke, and soot that was undesirable in city streets. The most successful of Lamm's designs was " Lamm's Fireless Engine", which ran on the St. Charles Streetcar Line in New Orleans in the 1870s and 1880s, and also saw wide use in the street railways of Paris. Biography Émile Lamm was born in Aÿ, Marne, France. After emigrating to the United States in 1848, he registered various patents in the field of dental medicineAmerican Society of Dental Su ...

Inventor
An invention is a unique or novel device, method, composition, idea, or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. The ideation process may be augmented by the applications of algorithms and methods from the domain collectively known as artificial intelligence . Some inventions can be patented. The system of patents wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dentist
A dentist, also known as a dental doctor, dental physician, dental surgeon, is a health care professional who specializes in dentistry, the branch of medicine focused on the teeth, gums, and mouth. The dentist's supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and sometimes dental therapists. History Middle Ages In China as well as France, the first people to perform dentistry were barbers. They have been categorized into 2 distinct groups: guild of barbers and lay barbers. The first group, the Guild of Barbers, was created to distinguish more educated and qualified dental surgeons from lay barbers. Guild barbers were trained to do complex surgeries. The second group, the lay barbers, were qualified to perform regular hygienic services such as shaving and tooth extraction as well as basic surgery. However, in 1400, France made decrees prohibiting lay barbers from practicing all t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Louisiana
Louisiana ( ; ; ) is a state in the Deep South and South Central regions of the United States. It borders Texas to the west, Arkansas to the north, and Mississippi to the east. Of the 50 U.S. states, it ranks 31st in area and 25th in population, with roughly 4.6 million residents. Reflecting its French heritage, Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). Baton Rouge is the state's capital, and New Orleans, a French Louisiana region, is its most populous city with a population of about 363,000 people. Louisiana has a coastline with the Gulf of Mexico to the south; a large part of its eastern boundary is demarcated by the Mississippi River. Much of Louisiana's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh a ...

Street Railway
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Streetcars In New Orleans
Tram, Streetcars have been an integral part of the public transportation network of New Orleans since the first half of the 19th century. The longest of the city's streetcar lines, the St. Charles Streetcar Line, St. Charles Avenue line, is the oldest continuously operating street railway system in the world. Today, the streetcars are operated by the New Orleans Regional Transit Authority (RTA). There are currently five operating streetcar lines in New Orleans: The St. Charles Streetcar Line, St. Charles Avenue Line, the Riverfront Streetcar Line, Riverfront Line, the Canal Streetcar Line, Canal Street Line (which has two branches), and the Rampart–Loyola Streetcar Line, Rampart-Loyola Line. The St. Charles Avenue Line is the only line that has operated continuously throughout New Orleans' streetcar history (though service was interrupted after Hurricane Katrina in August 2005 and resumed only in part in December 2006, as noted below). All other lines were replaced by bus ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Horsecar
A horsecar, horse-drawn tram, horse-drawn streetcar (U.S.), or horse-drawn railway (historical), is a tram or streetcar pulled by a horse. Summary The horse-drawn tram (horsecar) was an early form of public transport, public rail transport, which developed out of wagonway, industrial haulage routes that had long been in existence, and from the Omnibus (Horse-drawn vehicle), horse-drawn omnibus routes that first ran on public streets in the 1820s, using the newly improved iron or steel rail or 'Tramway (industrial), tramway'. They were local versions of the stagecoach lines and picked up and dropped off passengers on a regular route, without the need to be pre-hired. Horsecars on tramlines were an improvement over the omnibus, because the low rolling resistance of metal wheels on iron or steel track (rail transport), rails (usually Rail profile#Grooved rail, grooved Tram#History, from 1852 on) allowed the horses to haul a greater load for a given effort than the omnibus, and ga ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its Steam locomotive components, cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a Tender (rail), tender coupled to it. #Variations, Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fireless Locomotive
A fireless locomotive is a type of locomotive which uses reciprocating engines powered from a reservoir of compressed air or steam, which is filled at intervals from an external source. They offer advantages over conventional steam locomotives of lower cost per unit, cleanliness, and decreased risk from fire or boiler explosion; these are counterbalanced by the need for a source to refill the locomotive, and by the limited range afforded by the reservoir. They were desirable in situations where smoke from a firebox would be too noxious, or where there was risk of fire or explosion. Typical usage was in a mine, or a food or chemical factory. They were also used where a source of air or steam was readily available, and for moving loads within limited areas, such as a switch yard or within an industrial factory. They were eventually replaced for most uses by diesel and battery electric locomotives fitted with protective appliances; these are described as flame-proof locomotives. ...

Tramways In Île-de-France
The Île-de-France tramways () is a network of modern tram lines in the Île-de-France region of France. Fifteen lines are currently operational (counting Lines T3a and T3b as separate lines), with extensions and additional lines in both construction and planning stages. Although the system mainly runs in the suburban regions of Paris, lines T3a and T3b run entirely within Paris city limits, while lines T2 and T9 start their routes within Paris' borders. While lines operate independently of each other and are generally unconnected, some connections do exist: between lines T2 and T3a (at the Porte de Versailles station, since 2009), T3a and T3b (at the Porte de Vincennes station, since 2012), T1 and T5 (at the Marché de Saint-Denis station, since 2013), T1 and T8 (at the Saint-Denis train station, since 2014), T8 and T11 (at two stations: Villetaneuse-Université and Épinay-sur-Seine, since 2017), T3a and T9 (at the Porte de Choisy station, since 2021) and T6 and T10 (at H ...
