Bradford Colliery
Bradford Colliery was a coal mine in Bradford, Manchester, England. Although part of the Manchester Coalfield, the seams of the Bradford Coalfield correspond more closely to those of the Oldham Coalfield. The Bradford Coalfield is crossed by a number of fault lines, principally the Bradford Fault, which was reactivated by mining activity in the mid-1960s. Coal had been mined at Bradford since at least the early 17th century, when the area around the pits was largely rural; it became increasingly built-up and industrialised as nearby Manchester expanded during the 19th century. Coal was transported from the colliery by canal and railway, but most was consumed locally by the adjacent Bradford Ironworks. In the mid-20th century a 469-yard (420 m) tunnel was dug to supply coal directly to the Stuart Street Power Station. Damage to buildings in the area around the colliery caused by subsidence led to it becoming uneconomic despite its sitting on large reserves of high-quality coal, ...

Mosley Baronets
There have been three baronetcies created for members of the Mosley family, one in the Baronetage of England and two in the Baronetage of Great Britain. Only one creation is extant. Since 1980, the title has been held jointly with Baron Ravensdale in the Peerage of the United Kingdom. First baronetcy The first Mosley Baronetcy, of Rolleston in the County of Stafford, was created in the Baronetage of England on 10 July 1640 for Edward Mosley, of Rolleston Hall, a grandson of Sir Nicholas Mosley of Hough End Hall (who acquired the Manor of Manchester in 1596 and was Lord Mayor of London in 1599) and nephew of the lawyer Sir Edward Mosley (the youngest son of Sir Nicholas and his first wife Marjorie, née Whitbroke). Sir Edward was a lawyer who had been knighted by King James I of England in 1614; appointed a justice of the peace and Attorney-General for the Duchy of Lancaster; and elected as a member of parliament for Preston in 1614, 1620–2, and 1624–5. It was Sir Edward who f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Tar
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It is a type of creosote. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railroad tie preservative and used in the surfacing of roads. Coal tar was listed as a known human carcinogen in the first Report on Carcinogens from the U.S. Federal Government. Coal tar was discovered circa 1665 and used for medical purposes as early as the 1800s. Circa 1850, the discovery that it could be used as the main ingredient in synthetic dyes engendered an entire industry. It is on the World Health Organization's List of Essential Medicines. Coal tar is available as a generic medication and over the counter. Side effects include skin irritation, sun sensitivity, allergic reactions, and skin discoloration. ...

Carbolic Acid
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to wate ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Bradford Colliery Brickworks
Bradford Colliery Brickworks operated on the site of the Bradford Colliery in Bradford, Greater Manchester, then in the historic county of Lancashire, England, between the early 1870s and 1903. To exploit the seams of fireclay Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of alumin ... found between the coal seams, colliery manager Edward Williams built a large kiln to a design patented in 1870 by Friedrich Hoffmann, which permitted the continuous production of bricks. One of the largest brick-making facilities in the area, the kiln was more than long and wide, and probably contained 12–14 separate firing chambers. The kiln fell into disuse after the colliery's fireclay workings were abandoned in 1903, and it was eventually demolished in the late 1940s. An archaeological excavation car ...

Windlass
The windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. The Greek scientist Archimedes was the inventor of the windlass. The oldest depiction of a windlass for raising water can be found in the Book of Agriculture published in 1313 by the Chinese official Wang Zhen of the Yuan Dynasty ( 1290–1333). Uses *Vitruvius, a military engineer writing about 28 BC, defined a machine as "a combination of timber fastened together, chiefly efficacious in moving great weights." About a century later, Hero of Alexandria summarized the practice of his day by naming the "five simple machines" for "moving a given weight by a given force" as the lever, windlass, screw for power, wedge, and tackle block (pulley). Until nearly the end of the nine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hundredweight
The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and US customary unit of weight or mass. Its value differs between the US and British imperial systems. The two values are distinguished in American English as the "short" and "long" hundredweight and in British English as the "cental" and the "imperial hundredweight". * The short hundredweight or cental of is used in the United States. * The long or imperial hundredweight of 8 stone or is defined in the imperial system. Under both conventions, there are 20 hundredweight in a ton, producing a " short ton" of 2,000 pounds and a " long ton" of 2,240 pounds. History The hundredweight has had many values. In England in around 1300, different "hundreds" (''centum'' in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 lb. The United States and Canada came to use the ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Daglish
Robert Daglish (1779-1865) was a colliery manager, mining, mechanical and civil engineer at the start of the railway era. Daglish was born in North East England. He became a member of the Institution of Civil Engineers in 1830. He died at Orrell on 28 December 1865 and is buried at the Church of St Thomas the Martyr, Upholland. He had married Margaret Twizel in 1804. Their children included George (1805-1870), who became a surgeon and Robert. Dalglish moved to Lancashire in 1804 where he was employed by Lord Balcarres to manage Haigh Foundry and the adjacent Brock Mill Forge. While at Haigh he built pumping, winding and blast engines which in their day were described as "improved and efficient machines". Around 1810, Daglish moved to Orrell where he was appointed manager of John Clarke's Orrell Colliery. Having seen the rack locomotives John Blenkinsop designed for the Middleton Railway near Leeds in 1812, under licence, he built the ''Yorkshire Horse'' to the same design as B ...

Hoist (mining)
In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft. Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (thyristors), however modern large hoists use alternating current drives that are variable frequency controlled. There are three principal types of hoists used in mining applications: Drum hoist Drum hoists are the most common type of hoist used in North America, South Africa and South America. When using a drum hoist the hoisting cable is wound around the drum when the conveyance is lifted. Single-drum hoists can be used in smaller applications, however double-drum hoists easily allow the hoisting of two conveyances in balance (i.e. one skip being lifted while a second skip is being lowered). Drum hoists are mounted on concrete slabs within a hoistroom, the hoisting ropes run from the drum, up to the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headframe
A headframe (also known as a gallows frame, winding tower, hoist frame,Ernst, Dr.-Ing. Richard (1989). ''Wörterbuch der Industriellen Technik'' (5th ed.). Wiesbaden: Oscar Brandstetter, 1989. pit frame, shafthead frame, headgear, headstock or poppethead) is the structural frame above an underground mine shaft so as to enable the hoisting of machinery, personnel, or materials. Design Modern headframes are built out of steel, concrete or a combination of both. Timber headframes are no longer used in industrialized countries, but are still used in developing nations. Conventionally steel headframes are used when a drum hoist is employed, and concrete headframes are built for friction hoists; however a steel headframe can be used with a friction hoist for shafts with a smaller capacity and depth. Steel headframes A steel headframe is less expensive than a concrete headframe; the tallest steel headframe measures 87 m. Steel headframes are more adaptable to modifications (mak ...

Fine Spinners And Doublers
Fine Spinners and Doublers was a major cotton spinning business based in Manchester, England. At its peak it was a constituent of the FT 30 index of leading companies on the London Stock Exchange. History Formation Fine Spinners and Doublers, formed from a group of spinning companies specialising in fine Sea Island Cottons, was registered on 31 March 1898. The Fine Cotton Spinners and Doublers Association Limited had the objective of promoting the interests of cotton spinners in North West England. It was founded through the efforts of Herbert Dixon and Scott Lings in 1897. Businesses that joined in this enterprise at the time included A&G Murray Ltd, Houldsworths, CE Bennett & Co, James & Wainwright Bellhouse and McConnell & Co; but many more followed in subsequent years. The new association was vast compared with its competitors and its large size enabled it to secure its supplies of cotton from the Sea Island and Egypt. For thirty years it was the world's largest cotto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
