Hiram Maxim
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born British inventor best known as the creator of the first automatic machine gun, the Maxim gun. Maxim held patents on numerous mechanical devices such as hair-curling irons, a mousetrap, and steam pumps. Maxim laid claim to inventing the lightbulb. Maxim experimented with powered flight; his large aircraft designs were never successful. Circa 1904 he designed a highly successful amusement ride called the "Captive Flying Machine" to fund his research while generating public interest in flight. Maxim moved from the United States to the United Kingdom at the age of 41, and remained an American citizen until he became a naturalised British citizen in 1899, and received a knighthood in 1901. Birth and early life Maxim was born in Sangerville, Maine on 5 February 1840, into a family of French Huguenot origin. He became an apprentice Coach (vehicle), coachbuilder at the age of 14 and ten yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coach (vehicle)
A coach (also known as a motorcoach or coach bus) is a type of bus built for longer distance service, in contrast to transit buses that are typically used for shorter journeys within a single metropolitan region. Often used for Bus#Tourism, touring, intercity bus service, intercity, and international bus service, coaches are also used for Bus#Private charter, private charter for various purposes. Deriving the name from coach (carriage), horse-drawn carriages and stagecoaches that carried passengers, luggage, and mail, modern motor coaches are almost always high-floor buses, with separate luggage hold mounted below the passenger compartment. In contrast to transit buses, motor coaches typically feature forward-facing seating, with no provision for standing. Other accommodations may include onboard restrooms, televisions, and overhead luggage space. The name used for this type of bus varies between countries. In United States they are officially designated as motorcoach ''("a bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Huguenot
The Huguenots ( , ; ) are a Religious denomination, religious group of French people, French Protestants who held to the Reformed (Calvinist) tradition of Protestantism. The term, which may be derived from the name of a Swiss political leader, the Genevan burgomaster Besançon Hugues, was in common use by the mid-16th century. ''Huguenot'' was frequently used in reference to those of the Reformed Church of France from the time of the Protestant Reformation. By contrast, the Protestant populations of eastern France, in Alsace, Moselle (department), Moselle, and Montbéliard, were mainly Lutheranism, Lutherans. In his ''Encyclopedia of Protestantism'', Hans Hillerbrand wrote that on the eve of the St. Bartholomew's Day massacre in 1572, the Huguenot community made up as much as 10% of the French population. By 1600, it had declined to 7–8%, and was reduced further late in the century after the return of persecution under Louis XIV, who instituted the ''dragonnades'' to forcibly ...

Knighthood
A knight is a person granted an honorary title of a knighthood by a head of state (including the pope) or representative for service to the monarch, the church, or the country, especially in a military capacity. The concept of a knighthood may have been inspired by the ancient Greek ''hippeis'' (ἱππεῖς) and Roman ''equites''. In the Early Middle Ages in Western Christian Europe, knighthoods were conferred upon mounted warriors. During the High Middle Ages, a knighthood was considered a class of petty nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. In the Middle Ages, a knighthood was closely linked with horsemanship (and especially the joust) from its origins ...

British Citizen
The primary law governing nationality in the United Kingdom is the British Nationality Act 1981, which came into force on 1 January 1983. Regulations apply to the British Islands, which include the UK itself (England, Wales, Scotland, and Northern Ireland) and the Crown dependencies (Jersey, Guernsey, and the Isle of Man); and the 14 British Overseas Territories. The six classes of British nationality each have varying degrees of civil and political rights, due to the UK's historical status as a colonial empire. The principal class of British nationality is British citizenship, which is associated with the British Islands. British nationals associated with an overseas territory are British Overseas Territories citizens (BOTCs). Almost all BOTCs (except for those from Akrotiri and Dhekelia) have also been British citizens since 2002. Individuals connected with former British colonies may hold residual forms of British nationality, which do not confer an automatic right of abo ...

Naturalization
Naturalization (or naturalisation) is the legal act or process by which a non-national of a country acquires the nationality of that country after birth. The definition of naturalization by the International Organization for Migration of the United Nations excludes citizenship that is automatically acquired (e.g. at birth) or is acquired by declaration. Naturalization usually involves an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture. To counter multiple citizenship, some countries require that applicants for naturalization renounce any other citizenship that they currently hold, but whether this renunciation actually causes loss of original citizen ...

Flight
Flight or flying is the motion (physics), motion of an Physical object, object through an atmosphere, or through the vacuum of Outer space, space, without contacting any planetary surface. This can be achieved by generating aerodynamic lift associated with gliding flight, gliding or air propulsion, propulsive thrust, aerostatically using buoyancy, or by ballistics, ballistic movement. Many things can fly, from Flying and gliding animals, animal aviators such as birds, bats and insects, to natural gliders/parachuters such as patagium, patagial animals, anemochorous seeds and ballistospores, to human inventions like aircraft (airplanes, helicopters, airships, balloons, etc.) and rockets which may propel spacecraft and spaceplanes. The engineering aspects of flight are the purview of aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the atmosphere, and astronautics, the study of vehicles that travel through space, and ballistics, ...

Amusement Ride
Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people to create fun and enjoyment. Rides are often perceived by many as being scary or more dangerous than they actually are. This could be due to the design, having acrophobia, or from hearing about accidents involving rides that are similar. For some, the adrenaline associated with riding amusement rides is part of the experience. They are common at most annual events such as fairs, traveling carnivals, and circuses around the world. Sometimes music festivals and concerts also host amusement park rides. Types of rides * Flat rides are usually those that move their passengers on a plane generally parallel to the ground, such as rides that spin around a vertical axis, like carousels and twists; and ground-level rides such as bumper cars. The term is also used to refer to amusement rides that are not classified as dark rides, rollercoasters, transport rides, or water rides. * ...

Steam Pump
A pump is a device that moves fluids (liquids or gases), or sometimes Slurry, slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Mechanical pumps serve in a wide range of applications such as Water well pump, pumping water from wells, aquarium filtering, pond filtering and Water aeration, aeration, in the car industry for Water cooling, water-cooling and fuel injection, in the energy industry for Pumping (oil well), pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and Penile implant, penile prosthesis. When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a ''multi-stage pump''. T ...
