John Oldham (engineer)
John Oldham (1779–1840) was an Irish people, Irish engineer, now best known for the Oldham coupler. Life Born in Dublin, Oldham was apprenticed to an engraver there, but then became a miniature-painter. He invented a numbering machine, which in 1809 he unsuccessfully offered to the bank of Newry for numbering their banknotes. In 1812 the machine was adopted by the Bank of Ireland, and he received the appointment of engineer and chief engraver. In 1837 Oldham entered the service of the Bank of England, where he introduced improvements in the machinery for printing and numbering banknotes. This machinery continued in use until 1852–3, when the system of surface-printing was adopted. He died at his house in Montagu Street, Russell Square, London, on 14 February 1840. Engineer Oldham also paid attention to marine propulsion, and in 1817 he obtained a patent (No. 4169) for propelling ships by means of paddles worked by a steam-engine, an attempt to imitate the motion of a paddle ...

Irish People
The Irish ( ga, Muintir na hÉireann or ''Na hÉireannaigh'') are an ethnic group and nation native to the island of Ireland, who share a common history and culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also conquered parts of Ireland in the 12th century, while England's 16th/17th century conquest and colonisation of Ireland brought many English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Ireland) and Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities including British, Irish, Northern Irish or som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldham Coupler
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. Uses Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfer power to pump through coupling). Other common uses: * To alter the vibration characteristics of rotating units * To connect the driving and the driven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Newry
Newry (; ) is a city in Northern Ireland, divided by the Clanrye river in counties Armagh and Down, from Belfast and from Dublin. It had a population of 26,967 in 2011. Newry was founded in 1144 alongside a Cistercian monastery, although there are references to earlier settlements in the area, and is one of Ireland's oldest towns. The city is an entry to the " Gap of the North", from the border with the Republic of Ireland. It grew as a market town and a garrison and became a port in 1742 when it was linked to Lough Neagh by the first summit-level canal built in Ireland or Great Britain. A cathedral city, it is the episcopal seat of the Roman Catholic Diocese of Dromore. In 2002, as part of Queen Elizabeth's Golden Jubilee celebrations, Newry was granted city status along with Lisburn.

Banknote
A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable instrument, negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to Redemption value, redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authority, monetary authorities. National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This p ...

Bank Of England
The Bank of England is the central bank of the United Kingdom and the model on which most modern central banks have been based. Established in 1694 to act as the English Government's banker, and still one of the bankers for the Government of the United Kingdom, it is the world's eighth-oldest bank. It was privately owned by stockholders from its foundation in 1694 until it was nationalised in 1946 by the Attlee ministry. The Bank became an independent public organisation in 1998, wholly owned by the Treasury Solicitor on behalf of the government, with a mandate to support the economic policies of the government of the day, but independence in maintaining price stability. The Bank is one of eight banks authorised to issue banknotes in the United Kingdom, has a monopoly on the issue of banknotes in England and Wales, and regulates the issue of banknotes by commercial banks in Scotland and Northern Ireland. The Bank's Monetary Policy Committee has devolved responsibility for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russell Square
Russell Square is a large garden square in Bloomsbury, in the London Borough of Camden, built predominantly by the firm of James Burton. It is near the University of London's main buildings and the British Museum. Almost exactly square, to the north is Woburn Place and to the south-east is Southampton Row.

Aaron Manby
''Aaron Manby'' was a landmark vessel in the science of shipbuilding as the first iron steamship to go to sea. She was built by Aaron Manby (1776–1850) at the Horseley Ironworks. She made the voyage to Paris in June 1822 under Captain (later Admiral) Charles Napier, with Aaron's son Charles on board as engineer. ''Aaron Manby'' was then used by the ''Compagnie des bateaux a vapeur en fer'' to operate its service between Paris and Le Havre. Vessel history Launched in 1821, ''Aaron Manby'' was the first steamship to be built of iron. She was the brainchild of the eccentric but far-seeing naval officer Captain (later Admiral) Charles Napier, who had conceived the idea of a fleet of steamships for service on the River Seine. The ship was named after the master of the Horseley Ironworks, Tipton, Staffordshire, where she was pre-fabricated to a design jointly formulated by Captain Napier, Aaron Manby and his son Charles. She was then shipped in pieces to Rotherhithe on the Thame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle-wheel
A paddle wheel is a form of waterwheel or impeller in which a number of paddles are set around the periphery of the wheel. It has several uses, of which some are: * Very low-lift water pumping, such as flooding paddy fields at no more than about height above the water source. * To move and mix algae culture in the raceway ponds used for algaculture. * Propulsion of watercraft (as a paddlewheel) * Low head hydro power (as a waterwheel) * Flow sensors * Aerators The paddle wheel is an ancient invention but is still used today in a wide range of industrial and agriculture applications. Ship propulsion Paddle wheels would enable ships to travel without needing wind or oars. They were made obsolete by propellers, which had greater propulsion with lower weight and fuel usage. This was demonstrated by an 1845 tug-of-war competition between and with the screw-driven ''Rattler'' pulling the paddle steamer ''Alecto'' backward at .
