River Cray
The River Cray is the largest tributary of the Darent. It is the prime river of outer, south-east Greater London, rising in Priory Gardens, Orpington, where rainwater percolates through the chalk bedrock of the Downs to form a pond where the eroded ground elevation gives way to impermeable clay. Initially it flows true to form northwards, past industrial and residential St Mary Cray, through St Paul's Cray (where it once powered a paper mill) and through Foots Cray, where it enters the parkland Foots Cray Meadows, flowing under by Five Arches bridge (built in 1781 as part of their designs by Capability Brown). It then flows by restored Loring Hall (c.1760), home of the Lord Castlereagh who took his own life there in 1822. It continues through North Cray and Bexley. It neighbours a restored Gothic (architecture) cold plunge bath house, built around 1766 as part of Vale Mascal Estate. It is then joined by the River Shuttle (a small brook) and then continues through the parkland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orpington
Orpington is a town and area in south east London, England, within the London Borough of Bromley. It is 13.4 miles (21.6 km) south east of Charing Cross. On the south-eastern edge of the Greater London Built-up Area, it is south of St Mary Cray, west of Ramsden, north of Goddington and Green Street Green, and east of Crofton and Broom Hill. Orpington is covered by the BR postcode area. It is identified in the London Plan as one of 35 major centres in Greater London. History Stone Age tools have been found in several areas of Orpington, including Goddington Park, Priory Gardens, the Ramsden estate, and Poverest. Early Bronze Age pottery fragments have been found in the Park Avenue area. During the building of Ramsden Boys School in 1956, the remains of an Iron Age farmstead were excavated. The area was occupied in Roman times, as shown by Crofton Roman Villa and the Roman bath-house at Fordcroft. During the Anglo-Saxon period, Fordcroft Anglo-Saxon cemeter ...

A2 Road (Great Britain)
The A2 is a major road in south-east England, connecting London with the English Channel port of Dover in Kent. This route has always been of importance as a connection between London and sea trade routes to Continental Europe. It was originally known as the Dover Road. The M2 motorway has replaced part of the A2 as the strategic route. Unlike the other single digit A-roads in Great Britain, the A2 does not form a zone boundary. The boundary between Zones 1 and 2 is the River Thames. History of the route The route of the current A2 follows a similar route to that of a Celtic ancient trackway. It was an important route for the Romans linking London with Canterbury and the three Channel ports of Rutupiae (now Richborough), Dubris (now Dover) and Portus Lemanis (in modern Lympne). It had river crossings at Rochester over the River Medway; Dartford (River Darent) and Crayford (River Cray). The Romans paved the road and constructed the first Rochester Bridge across the Medway. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snodland
Snodland is a town in the borough of Tonbridge and Malling in Kent, England. It lies on the River Medway, between Rochester, Kent, Rochester and Maidstone, and from central London. At the 2011 Census, it had a population of 10,211. History "Snoddingland" is first mentioned in a charter of 838 in which King Egbert of Wessex gave "four ploughlands in the place called Snoddingland and Holanbeorge" (Holborough) to Beornmod, the Bishop of Rochester. Since -ing#Other meanings of the suffix, -ingland names are mostly derived from personal names, the name appears to refer to 'cultivated land connected with Snodd' or Snodda. The Domesday Book refers to it as "Esnoiland". The first Roman Empire, Roman advance in the Roman conquest of Britain, conquest of Britain may have crossed the River Medway near Snodland, although there are other possible locations. The supposed crossing place is marked by a memorial on the opposite side of the river from Snodland, close to Burham. Near this sp ...

Charles Cowan
Charles Cowan (7 June 1801 – 1889) was a Scottish politician and paper-maker. Life He was born in Charlotte Street, Edinburgh, Charlotte Street in Edinburgh on 7 June 1801, the son of Alexander Cowan, papermaker and philanthropist, and Elizabeth Hall, daughter of George Hall a merchant in Crail in Fife. He was the eldest of eleven children, eight of whom survived until adulthood. He was educated at Penicuik Parish School 1806-11 and then the High School in Edinburgh. He then attended university both in Edinburgh University, Edinburgh (1814–17) and Geneva (1817-18). He then followed his father into the paper-making industry. He wrote the article on papermaking for the ''Encyclopædia Britannica''. In May 1819, he was sent to learn the papermaking trade at St Mary Cray, Kent, where he worked at either Lay's or Hall's mill on the River Cray. In the 1847 United Kingdom general election, general election of June 1847, he ran as a Radicals (UK), Radical free-trade candidate in ...

Corn Mill
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding. History Early history The Greek geographer Strabo reports in his ''Geography'' a water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira, Asia Minor, before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the " Norse wheel", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "bed", a stone of a similar size and shape. This simple arrangement required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watermark
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting. There are two main ways of producing watermarks in paper; the ''dandy roll process'', and the more complex ''cylinder mould process''. Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. Various aids have been developed, such as ''watermark fluid'' that wets the paper without damaging it. A watermark is very useful in the examination of paper because it can be used for dating documents and artworks, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper. The word is also used for digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papermaking
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression. In papermaking, a dilute suspension consisting mostly of separate cellulose fibres in water is drained through a sieve-like screen, so that a mat of randomly interwoven fibres is laid down. Water is further removed from this sheet by pressing, sometimes aided by suction or vacuum, or heating. Once dry, a generally flat, uniform and strong sheet of paper is achieved. Before the invention and current widespread adoption of automated machinery, all paper was made by hand, formed or laid one sheet at a time by specialized laborers. Even today those who make paper by hand use tools and technologies quite similar to those existing hundreds of years ago, as originally developed in China and other ...

Sittingbourne
Sittingbourne is an industrial town in Kent, south-east England, from Canterbury and from London, beside the Roman Watling Street, an ancient British trackway used by the Romans and the Anglo-Saxons and next to the Swale, a strip of sea separating mainland Kent from the Isle of Sheppey. The town became prominent after the death of Thomas Becket in 1170, since it provided a convenient resting point on the road from London to Canterbury and Dover. Chatham Main Line links to London Victoria and HS1 to St Pancras International, the journey taking about an hour from Sittingbourne railway station. History Sittingbourne owes its name to a modernised version of an observation on its location. The town's name came from the fact that there is a small stream or "bourne" running underground in part of the town. Hasted writing in the 1790s in his ''History of Kent'' states that: The Kent Hundred Rolls of 1274–5, preserved in the National Archives, record Sittingbourne as Sydingeburn ...

Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the ...

Millstone
Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones. Millstones come in pairs: a convex stationary base known as the ''bedstone'' and a concave ''runner stone'' that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones. Millstones are constructed so that their shape and configuration help to channel ground flour to the outer edges of the mechanism for collection. The runner stone is supported by a cross-shaped metal piece (millrind or rynd) fixed to a "mace head" topping the main shaft or spindle leading to the driving mechanism of the mill (wind, water (including tide) or other means). History The earliest evidence for stones used to grind food is found in northern Australia, at the Madjedbebe rock shelter in Arnhem Land, dating back around 60,000 years. Grinding stones or grindston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterwheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...
