London Pneumatic Despatch Company
The London Pneumatic Despatch Company (also known as the London Pneumatic Dispatch Company) was formed on 30 June 1859, to design, build and operate an underground railway system for the carrying of mail, parcels and light freight between locations in London. The system was used between 1863 and 1874. Background Sir Rowland Hill of the General Post Office commissioned two engineers to investigate the feasibility of a pneumatic tube-based system between the General Post Office and the West District Central Post Office. In 1855 and 1856 they reported favourably but there would be significant cost. The scheme was not progressed. In 1859 Thomas Webster Rammell and Josiah Latimer Clark proposed an underground tube network in central London "for the more speedy and convenient circulation of despatches and parcels". The company was founded in 1859 with offices at 6 Victoria Street, Westminster. Capital of £150,000 was sought through 15,000 shares at £10 each. The company's direc ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postal System Of The United Kingdom
Postal services in the United Kingdom are provided predominantly by the Royal Mail (and Post Office Limited which oversees post offices). Since 2006, the market has been fully opened to competition which has had greater success in business-to-business delivery than in ordinary letter delivery. The industry is regulated by Ofcom and consumer interests are represented by Consumer Focus. Since 1 October 2011, the main piece of legislation is the Postal Services Act 2011, although some parts of the Postal Services Act 2000 are still in force. The 2011 Act enables the government to privatise Royal Mail and to possibly mutualise Post Office Limited. History The quality of postal services in the 17th and 18th centuries improved with development of better roads and means of transportation. Anthony Trollope is credited with major contributions to the development of postal services in the years 1851-1867, described, ''e.g.'' in Chapters 8 and 13 of his autobiography.Trollope, Anthony (18 ...

Pipeline Transport
Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes—a pipeline—typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries of the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. ''Pipeline and Gas Journals worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Post Office Railway
The Post Office Railway, is a narrow gauge, driverless underground railway in London that was built by the Post Office with assistance from the Underground Electric Railways Company of London, to transport mail between sorting offices. Inspired by the Chicago Tunnel Company, it opened in 1927 and operated for 76 years until it closed in 2003. A museum within the former railway was opened in September 2017. Geography The line ran from Paddington Head District Sorting Office in the west to the Eastern Head District Sorting Office at Whitechapel in the east, a distance of . It had eight stations, the largest of which was underneath Mount Pleasant, but by 2003 only three stations remained in use because the sorting offices above the other stations had been relocated. History Use as post office railway In 1911, a plan evolved to build an underground railway long from Paddington to Whitechapel serving the main sorting offices along the route; road traffic congestion was causing ...

It is primarily concerned with the social history of London and its inhabitants throughout time. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Post Office In St Martin Le Grand By Thomas Shepherd (late 1820s)
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Overend, Gurney And Company
Overend, Gurney & Company was a London wholesale discount bank, known as "the bankers' bank", which collapsed in 1866 owing about £11 million, equivalent to £ million in . The collapse of the institution triggered a banking panic. History Early years The business was founded in 1800 as Richardson, Overend and Company by Thomas Richardson, clerk to a London bill discounter, and John Overend, chief clerk in the bank of Smith, Payne and Company at Nottingham (absorbed into the National Provincial Bank in 1902), with Gurney's Bank (absorbed into Barclays Bank in 1896) supplying the capital. At that time, bill-discounting was carried on in a spasmodic fashion by the ordinary merchant in addition to his regular business, but Richardson considered that there was room for a London house which should devote itself entirely to the trade in bills. This idea, novel at the time, proved an instant success. Samuel Gurney joined the firm in 1807 and took control of Overend, Gurney and Co. in ...

General Post Office, London
The General Post Office in St. Martin's Le Grand (later known as GPO East) was the main post office for London between 1829 and 1910, the headquarters of the General Post Office of the United Kingdom of Great Britain and Ireland, and England's first purpose-built post office. It was demolished in 1912. History Originally known as the General Letter Office, the headquarters for the General Post Office (GPO) was built on the eastern side of St. Martin's Le Grand in the City of London between 1825 and 1829, to designs by Robert Smirke. This was the UK's second purpose-built post office. Dublin's GPO, completed in 1818 to a design by Francis Johnston, and still in use, predates it. It was built in the Grecian style with Ionic porticoes, and was long and deep. The building's main facade had a central hexastyle Greek Ionic portico with pediment, and two tetrastyle porticoes without pediments at each end. The main interior was the large letter-carriers' room, with its elegant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staveley Coal And Iron Company
The Staveley Coal and Iron Company Limited was an industrial company based in Staveley, near Chesterfield, North Derbyshire. History The company was registered in 1863, appearing in provincial stock exchange reports from 1864. It exploited local ironstone quarried from land owned by the Duke of Devonshire on the outskirts of the village. It developed into coal mining, owning several collieries and also into chemical production, first from those available from coal tar distillation, later to cover a wide and diverse range. Part of the plant at Staveley was a sulphuric acid manufacturing unit making use of the Contact Process. It was during the years of World War 1 that the company developed its chemical operations beyond coal-tar chemicals and began production of sulphuric and nitric acids. During the war they also made picric acid, TNT and guncotton. Following the end of hostilities the company laid plans to develop a range of chlorinated organics and to this end purchase ...
