River Cray
The River Cray is the largest tributary of the River 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 killed himself 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 parkla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bexley
Bexley is an area of south-eastern Greater London, England and part of the London Borough of Bexley. It is sometimes known as Bexley Village or Old Bexley to differentiate the area from the wider borough. It is located east-southeast of Charing Cross and south of Bexleyheath. Bexley was an ancient parish in the county of Kent. As part of the suburban growth of London in the 20th century, Bexley increased in population, becoming a municipal borough in 1935 and has formed part of Greater London since 1965. History Bexley was an ancient parish in Kent, in the diocese of Rochester, and under the Local Government Act 1894 formed part of Bexley Urban District. The urban district gained further status in 1935 as a municipal borough. Kent County Council formed the second tier of local government during that time. In 1965, London County Council was abolished and replaced by Greater London Council, with an expanded administrative area that took in the metropolitan parts of the ...

Charles Cowan
Charles Cowan (7 June 1801 – 1889) was a Scottish politician and paper-maker. Life He was born in 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 (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 general election of June 1847, he ran as a Radical free-trade candidate in Edinburgh, defeating the incumbent Whig Thomas Babington Macaulay. His initial election was declared n ...

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 reported in his ''Geography'' that a water-powered grain-mill 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 re ... [...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 questioned document examination, 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.

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 Pulp and paper industry, made using industrial machinery, while handmade paper survives as a specialized craft and a medium for paper art, 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 origin ...

Sittingbourne
Sittingbourne is an industrial town in the Swale district of Kent, southeast England, from Canterbury and from London, beside the Roman Watling Street, an ancient trackway used by the Romans and the Anglo-Saxons. The town stands 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 station 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 1274–75, preserved in the National Arch ...

Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, Textile, rags, poaceae, grasses, Feces#Other uses, herbivore dung, or other vegetable sources in water. Once the water is drained through a fine mesh leaving the fibre evenly distributed on the surface, it can be pressed and dried. The papermaking process developed in east Asia, probably China, at least as early as 105 Common Era, CE, by the Han Dynasty, Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BCE in China. Although paper was originally made in single sheets by hand, today it is mass-produced 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 Housekeeping, cleaning. It may also be used a ...

Millstone
Millstones or mill stones are stones used in gristmills, used for triturating, crushing or, more specifically, grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones. Millstones come in pairs: a stationary base with a convex rim known as the bedstone (or nether millstone) and a concave-rimmed 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 origins of an industry Often referred to as the "oldest industry", the use of the millstone is inextr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterwheel
A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial use well into the 20th century, although they are no longer in common use today. Water wheels are used for 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. Waterwheel ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, 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 iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domesday
Domesday Book ( ; the Middle English spelling of "Doomsday Book") is a manuscript record of the Great Survey of much of England and parts of Wales completed in 1086 at the behest of William the Conqueror. The manuscript was originally known by the Latin name , meaning "Book of Winchester", where it was originally kept in the royal treasury. The ''Anglo-Saxon Chronicle'' states that in 1085 the king sent his agents to survey every shire in England, to list his holdings and dues owed to him. Written in Medieval Latin, it was highly abbreviated and included some vernacular native terms without Latin equivalents. The survey's main purpose was to record the annual value of every piece of landed property to its lord, and the resources in land, labour force, and livestock from which the value derived. The name "Domesday Book" came into use in the 12th century. Richard FitzNeal wrote in the ( 1179) that the book was so called because its decisions were unalterable, like those of the ...
