Andrew Yarranton
Andrew Yarranton (1619–1684) was an important English engineer in the 17th century who was responsible for making several rivers into navigable waterways. Biography He was born at Astley, just south of the town of Stourport-on-Severn in Worcestershire, and was from a yeoman family. He was apprenticed to a linen draper in Worcester circa 1632, but left after a few years to live a country life. According to John Aubrey he died violently; 'The cause of death was a beating and thrown into a tub of water'. Civil War Period During the English Civil War he served in the Parliamentary army rising to the rank of captain. In 1646 he became a member of the Worcester County Committee to administer "parliamentary justice" to the county and to list and fine all "delinquents" who had supported the Royalist cause. After the war, he used the arrears of military pay to speculate in forfeited crown and royalist estates. With other officers, he set up ironworks, a blast furnace at Astley, to ...

English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common history and culture. The English identity is of History of Anglo-Saxon England, Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

Tinning
Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. The term is also widely used for the different process of coating a metal with solder before soldering. It is most often used to prevent rust, but is also commonly applied to the ends of stranded wire used as electrical conductors to prevent oxidation (which increases electrical resistance), and to keep them from fraying or unraveling when used in various wire connectors like twist-ons, binding posts, or terminal blocks, where stray strands can cause a short circuit. While once more widely used, the primary use of tinplate now is the manufacture of tin cans. Formerly, tinplate was used for cheap pots, pans, and other holloware. This kind of holloware was also known as tinware and the people who made it were tinplate workers. The untinned sheets employed in the manufacture are known as black plates. They are now made of steel, either Bessemer stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brine
Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, ''brine'' may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature). Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization (fresh water recovery). In nature Brines are produced in multiple ways in nature. Modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit call ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Droitwich Canal
The Droitwich Canal is a synthesis of two canals in Worcestershire, England; the Droitwich Barge Canal and the Droitwich Junction Canal. The Barge Canal is a broad canal which opened in 1771 linking Droitwich Spa to the River Severn at Hawford Bottom Lock, Claines. The Droitwich Junction Canal is a narrow canal, opened in 1854, which linked Droitwich to the Worcester and Birmingham Canal. Both were built to carry salt, and were abandoned in 1939. They have been the subject of a restoration plan since 1973, and the Barge Canal was officially reopened in 2010, while the Junction Canal reopened in July 2011. Following the opening of the canal, ownership transferred to the newly created Canal and River Trust History Droitwich has been an important centre for the production of salt, obtained from natural brine springs, since before Roman times. In order to get the product to market, an Act of Parliament was obtained in 1662 to authorise improvements to the River Salwarpe, but the w ...

Droitwich
Droitwich Spa (often abbreviated to Droitwich ) is an historic spa town in the Wychavon district in northern Worcestershire, England, on the River Salwarpe. It is located approximately south-west of Birmingham and north-east of Worcester. The town was called Salinae in Roman times, then later called Wyche, derived from the Anglo-Saxon Hwicce kingdom, referred to as "Saltwich" according to Anglo-Saxon charters, with the Droit (meaning "right" in French) added when the town was given its charter on 1 August 1215 by King John. The "Spa" was added in the 19th century when John Corbett developed the town's spa facilities. The River Salwarpe running through Droitwich is likely derived from ''sal'' meaning "salt" and ''weorp'' which means "to throw up" - i.e. "the river which throws up salt" - which overflows from the salt brines. The town is situated on massive deposits of salt, and salt has been extracted there since ancient times. The natural Droitwich brine contains of salt; te ...

River Salwarpe
The River Salwarpe is a long river in Worcestershire, England. It is a left bank tributary of the River Severn, which it joins near Hawford. Course The Salwarpe is formed by the confluence of the Battlefield and Spadesbourne Brooks in Bromsgrove, it then passes Stoke Prior, Upton Warren, Wychbold, Droitwich. Downstream of Droitwich, it passes Salwarpe, and then meets the River Severn, near Hawford. Andrew Yarranton attempted unsuccessfully to make it navigable in the 1660s, but in the 21st century a stretch of the river in Droitwich was canalized to link the Barge and Junction sections of the Droitwich Canal. Tributaries include the Elmbridge, Hadley and Hen brooks. Hydrology The flow of the Salwarpe has been measured in its lower reaches at Harford Hill since 1958. The long-term record shows that the catchment of to the gauging station yielded an average flow of . The highest river level recorded at the station occurred in January 1960 with a height of , giving a corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgical Furnace
A metallurgical furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in Metal, iron and steel production. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces. There are several different types of furnaces used in metallurgy to work with specific metal and ores. Smelting furnaces Smelting furnaces are used in smelting to extract metal from ore. Smelting furnaces include: * The blast furnace, used to Redox, reduce iron ore to pig iron ** Cold blast ** Hot blast * Steelmaking furnaces, including: ** Puddling furnace ** Reverberatory furnace ** ** Open hearth furnace ** Basic oxygen furnace ** Electric arc furnace ** Electric induction furnace Other furnaces * Furnaces used to remelt metal in Foundry, foundries. * Furnaces used to reheat and Heat treatment, heat treat metal for use in: ...

Forge
A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by forging, or to the point at which work hardening no longer occurs. The metal (known as the "workpiece") is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge. Types Coal/coke/charcoal forge A forge typically uses bituminous coal, indu ...

Dick Brook
Dick Brook is small tributary stream of the River Severn that flows through Worcestershire, England. The brook is formed from two small unnamed streams that converge at Joan’s Hole to the west of Dunley, Worcestershire, Dunley. The longest of these streams drains the area around Rock, Worcestershire, Rock, with a source near Clows Top. From Joan’s Hole the named brook flows generally south-east for a total distance of . At the edge of the village of Astley, Worcestershire, Astley it was dammed to power Priors Mill, and then to the south of the village, at New Bridge it is crossed by a packhorse bridge, below the monastery at Astley, Worcestershire#Glasshampton, Glasshampton. To the north of Noutard's Green it passes beneath Glazen Bridge (B4196), and along the northern edge of Shrawley wood, until it joins the River Severn. The drainage basin for the brook, which lies between that of the Gladder Brook to the north, and that of the Shrawley Brook to the south, has an area of ...
