Alfred Beach
Alfred Ely Beach (September 1, 1826 – January 1, 1896) was an American inventor, publisher, and patent lawyer, born in Springfield, Massachusetts. He is most known for his design of New York City's earliest subway predecessor, the Beach Pneumatic Transit. A member of the Union League of New York, he also patented a typewriter for the blind and a system for heating water with solar power. Early years Beach was born in Springfield, Massachusetts, and was the son of a prominent publisher, Moses Yale Beach. Alfred Beach worked for his father until he and a friend, Orson Desaix Munn, decided to buy ''Scientific American'', a relatively new publication. He also brought in the venture Salem Howe Wales, President of the New York City Department of Docks and co-founder of the Metropolitan Museum of Art. They ran ''Scientific American'' until their deaths decades later, and it was carried on by their sons and grandsons for decades more. Munn and Beach also established a very successful p ...

Springfield, Massachusetts
Springfield is a city in the Commonwealth of Massachusetts, United States, and the seat of Hampden County. Springfield sits on the eastern bank of the Connecticut River near its confluence with three rivers: the western Westfield River, the eastern Chicopee River, and the eastern Mill River. At the 2020 census, the city's population was 155,929, making it the third-largest city in Massachusetts, the fourth-most populous city in New England after Boston, Worcester, and Providence, and the 12th-most populous in the Northeastern United States. Metropolitan Springfield, as one of two metropolitan areas in Massachusetts (the other being Greater Boston), had a population of 699,162 in 2020. Springfield was founded in 1636, the first Springfield in the New World. In the late 1700s, during the American Revolution, Springfield was designated by George Washington as the site of the Springfield Armory because of its central location. Subsequently it was the site of Shays' Rebellio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnelling Shield
A tunnelling shield is a protective structure used during the excavation of large, man-made tunnels. When excavating through ground that is soft, liquid, or otherwise unstable, there is a potential health and safety hazard to workers and the project itself from falling materials or a cave-in. A tunnelling shield can be used as a temporary support structure. It is usually in place for the short-term from when the tunnel section is excavated until it can be lined with a permanent support structure. The permanent structure may be made up of, depending on the period, bricks, concrete, cast iron, or steel. Although modern shields are commonly cylindrical, the first "shield", designed by Marc Isambard Brunel, was actually a large, rectangular, scaffold-like iron structure with three levels and twelve sections per level, with a solid load-bearing top surface. The structure protected the men from cave-ins as they laboured within it, digging the tunnel out in front of the shield. History ...

Pneumatic Tube
Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids. In the late 19th and early 20th centuries, pneumatic tube networks gained acceptance in offices that needed to transport small, urgent packages, such as mail, other paperwork, or money, over relatively short distances, within a building or, at most, within a city. Some installations became quite complex, but have mostly been superseded. However, they have been further developed in the 21st century in places such as hospitals, to send blood samples and the like to clinical laboratories for analysis. A small number of pneumatic transportation systems were built for larger cargo, to compete with train and subway systems. However, they never gained popularity. History Historical ...

The New York Times
''The New York Times'' (''the Times'', ''NYT'', or the Gray Lady) is a daily newspaper based in New York City with a worldwide readership reported in 2020 to comprise a declining 840,000 paid print subscribers, and a growing 6 million paid digital subscribers. It also is a producer of popular podcasts such as '' The Daily''. Founded in 1851 by Henry Jarvis Raymond and George Jones, it was initially published by Raymond, Jones & Company. The ''Times'' has won 132 Pulitzer Prizes, the most of any newspaper, and has long been regarded as a national " newspaper of record". For print it is ranked 18th in the world by circulation and 3rd in the U.S. The paper is owned by the New York Times Company, which is publicly traded. It has been governed by the Sulzberger family since 1896, through a dual-class share structure after its shares became publicly traded. A. G. Sulzberger, the paper's publisher and the company's chairman, is the fifth generation of the family to head the pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marc Isambard Brunel
Sir Marc Isambard Brunel (, ; 25 April 1769 – 12 December 1849) was a French-British engineer who is most famous for the work he did in Britain. He constructed the Thames Tunnel and was the father of Isambard Kingdom Brunel. Born in France, Brunel fled to the United States during the French Revolution. In 1796, he was appointed Chief Engineer of New York City. He moved to London in 1799, where he married Sophia Kingdom. In addition to the construction of the Thames Tunnel, his work as a mechanical engineer included the design of machinery to automate the production of pulley blocks for the Royal Navy. Brunel preferred the given name Isambard, but is generally known to history as Marc to avoid confusion with his more famous son. Early life in France Brunel was the second son of Jean Charles Brunel and Marie-Victoire Lefebvre. Jean Charles was a prosperous farmer in Hacqueville, Normandy, and Marc was born on the family farm. It was customary for the first son to inher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, oil or, rarely, wood) to heat water in the locomotive's 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 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 coupled to it. 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 during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Pneumatics
Pneumatics (from Greek ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. Gases used in pneumatic systems Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Factory-plumb ...

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Metropolitan Railway
The Metropolitan Railway (also known as the Met) was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital's financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at , , and King's Cross to the City. The first section was built beneath the New Road using cut-and-cover between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield, near the City. It opened to the public on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives, the world's first passenger-carrying designated underground railway. The line was soon extended from both ends, and northwards via a branch from Baker Street. Southern branches, directly served, reached Hammersmith in 1864, Richmond in 1877 and the original completed the '' Inner Circle'' in 1884. The most important route was northwes ...

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

Beach Institute
Alfred Ely Beach High School, known as Beach High School, is a public high school in Savannah, Georgia, United States. Beach Institute In 1867, the Beach Institute was established by the American Missionary Association (A.M.A.) and the Freedmen's Bureau with funds donated by Alfred Ely Beach, editor of ''Scientific American''. The school was privately funded as a manual training school to provide support for newly freed African Americans. By 1874, the institute was appropriated by the Savannah-Chatham Board of Education for the purpose of providing free education to Savannah's African American citizenry. Although the Beach Institute closed its doors in 1915, it was reopened as an African American cultural center and is currently operated by the King-Tisdell Cottage Foundation. High School The Beach name survives in the name of Alfred E. Beach High School.
