History

Pneumatics can be traced back to Hero of Alexandria in the 1st century AD. A Victroians used capsule pipelines to transmit telegraph messages, or telegrams, to nearby buildings from telegraphy stations.

When it is ordinarily utilized for little parcels & documents, it were originally proposed in the early 1800s for transport of heavily freight. It was another time envisioned that massive networks one tubes can exist as utilized to shipping population.

Pneumatic Post

Pneumatic post or even pneumatic mail occurs as technique to deliver letters across pressurised air tubes. It was invented inside per Scottish engineer William Murdoch in the 1800's and was late developed per London Pneumatic Dispatch Company. These systems were utilized inside many big cities since a 2nd half of 19th century but was largely abandoned during 20th century.

It was too speculated that the body of tubes will deliver mail to each zero in the Usa. The major patterns inside Paris was in apply until 1983 when it was finally abandoned in favour of computers & facsimile machines. Now, around Prague, the Czech Republic, pneumatic tubes are however operating. This potrubní pošta service was opened around 1899 & today covers some Sixty kilometeres redeeming mail and little parcels.

Average todays applications come banks and hospitals. NumeroAmerica big retail merchant (like Page Depot or even even CostCo in the US) apply pneumatic tubes to transfer checks or more documents from either cashiers to the accounting professional. the single rules lists a speed of X m/s.

Stations of pneumatic post commonly attached post agents, stock index exhanges, banks & ministries. Italy was a merely united states to issue postage stamps (between 1913 and 1966) specifically for pneumatic post. Austria, France, & Germany issued postal stationary for pneumatic use.

Historical uses of pneumatic post

1853: linking a London Futures Exchange to the city's main telegraph station (220 front yard hanker) 1865: around Berlin (until 1976), a "Rohrpost", a technique 400 kilometers inside aggregate length 1866: within Paris (until 1983) 1875: around Vienna (until 1956) 1887: around Prague (until 2002 referable in flood) ([http://feed.proteinos.com/000613.html], [http://mobil.idnes.cz/mob_prakticky.asp?r=mob_prakticky&c=A040517_5258397_mob_prakticky] within Czech, by using pictures) more cities: Munich, Rio de Janeiro, Hamburg, Rome, Naples, Milan, Marseilles, Boston, Future York City, Philadelphia, Chicago, St. Louis

Pneumatic Transportation

(Pneumatic Transport on this button refers to the transporting of population within pneumatic tubes; more forms of transport that apply pneumatics for propulsion are non considered.)

Inside 1812, George Medhurst first proposed, but never implemented, blowing rider carriages across the burrow.

Brunel built an atmospheric railway on a 52-mile division of the South Devon Railway between Exeter and Plymouth, England in the 19th century It was also try the London & Croydon Railway in 1845, but was soon abolished.

Around 1861, the London Pneumatic Despatch Company built the rules big plenty to move the human, although it was designed for parcels. A October 10, 1865 inauguration of the new Holborn Station was marked by having a Duke of Buckingham, the chair, & a bit of of the directors of the company blown through the tube to Euston (a 5 microscopic hike).

The 600 front yard pneumatic rider railway was exhibited at the Crystal Palace in 1864. This was the image for the projected Whitehall Pneumatic Railway that would own start under a River Thames linking Waterloo and Charing Cross. Dig was began inside 1865 but was stopped in 1868 due to financial problems.

Within 1867 at the American Institute exhibition in New York, Alfred Ely Beach demonstrated a 107 foot hanker, Sestet foot across pipe that was capable of moving Xii rider + conductor. Inside 1869, the Beach Pneumatic Transit Company of Just released York constructed on the q.t. the 312 foot hanker, Nina from carolina foot across pneumatic subway line under Broadway. A line just operated for two or three months, closing fallowing Beach was abortive around contracting permission to extend it.

In the 1960s, Lockheed and MIT with the United States Department of Commerce did feasibility studies in the pneumatic train models powered by ambient atmospheric pressure & "gravitational pendulum assist" to attach cities on the East Coast of the United states of america. It estimated that a start between Philadelphia and New York would average 390 miles by the hour.

After victims plans were abandoned when as well expensive, Lockheed engineer L.K. Edwards founded Tube Transit, Inc. to develop technology based on "gravity-vacuum transportation". Around 1967 he proposed the Bay Front yard Gravity-Vacuum Transit for California that would run along side a so-under-construction BART system. It was never built.

Current usage

the technology is however utilized in a little shell. The big total of cautilize-higher banks use pneumatic tubes to conveyance cash & documents between cars & tellers. Virtually all hospitals have a body to deliver doses, documents & specimens to & from either nurses' stations. Numbers of manufacturing plant utilize the children to deliver area quickly through big campuses. Eventually, numerous big places have a single-way systems to securely transfer cash from either checkout stands to back agents. Denver International Airport is noteworthy for the large total of Swisslog Translogic pneumatic tube systems, including the Tenner-inch across models for moving aircraft arethe to remote concourses, a Quaternary-inch formulas for United Airlines ticketing, & a robust rules in the parking toll collection formulas using an outlet at each booth.

Pneumatic tubes in fiction

Whenever pneumatic tubes 1st inherit have in the 19th century, it symbolized technical progress & it was imagined that it would become park later. Jules Verne's Paris in the 20th Century (1863) includes suspended pneumatic tube trains that stretch across a oceans. Albert Robida's The Twentieth Century (1882) describes a 1950s Paris where tube trains keep around replaced railways, pneumatic mail is ubiquitous, & catering corporations compete to deliver meals in tap to humans's homes across pneumatic tubes. Edward Bellamy's Looking Backward (1888) envisions the world of 2000 as interlinked with tubes for redeeming goods. Michel Verne's An Express of the Future (1888) questions the sensibility of the transatlantic pneumatic subway. Inside Michel & Jules Verne's The Day of an American Journalist in 2889 (1889) submarine tubes carry people faster than aero-trains and the Society for Supplying Food to the Home allows subscribers to receive meals pneumatically.

Late, becaapply of their use by governments & big businesses, tubes began to symbolize bureaucracy. Around George Orwell's Nineteen Eighty-Four, pneumatic tubes in the Ministry of Truth deliver newspapers to Winston's desk containing articles to be "rectified". A pic Brazil, which hwhen similar themes, also utilized tubes (also as more anachronic technology) to evoke a stagnation of bureaucracy. Ab initio of every episode of the 1999 television series Fantasy Island, a darker version of the original, bookings for would-manque visitant to the Island were sent to the devilish Mr. Roarke via the pneumatic tube from either a dusty old travel professional, making the tube seem non such bureaucratic when sinister.

A failure of pneumatic tubes to fulfill their possible every bit envisioned inside former centuries has set the babies in the company of flying cars and dirigibles as ripe for ironic retro-futurism. A 1960s cartoon series The Jetsons featured pneumatic tubes that people can step into & become sucked higher & fleetly spit retired at their destination. Futurama imagined similar devices for the citizens of 31st century New New York.

However, another time the tube is upright the tube, & non entirely pneumatic tubes inside fiction come symbolical or even meaningful beyond just existence interesting technology. In the James Bond film The Living Daylights, a supposed Soviet deserter was smuggled through a Iron Curtain in an oil pipe-line. Patch non technically a pneumatic tube, the project of the transportation within ''Logan's Run'', in which cars traveled in elevated clear tubes, seems influenced by pneumatic tube aesthetics.
