Tinplate
Tinplate consists of sheets of steel coated with a thin layer of tin to impede rusting. Before the advent of cheap milled steel, the backing metal was wrought iron. While once more widely used, the primary use of tinplate now is the manufacture of tin cans. Tinplate is made by rolling the steel (or formerly iron) in a rolling mill, removing any mill scale by pickling it in acid and then coating it with a thin layer of tin. Plates were once produced individually (or in small groups) in what became known as a ''pack mill''. In the late 1920s pack mills began to be replaced by ''strip mills'' which produced larger quantities more economically. 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. For many purposes, tinplate has been replaced by galvanised (zinc-coated or tinned) vessels, though not for cooking as zinc is poisonous. The zinc layer prevents the iron f ...

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] |
Wolverley
Wolverley is a village; with nearby Cookley (1 mi northeast), it forms a civil parish in the Wyre Forest District of Worcestershire, England. It is 2 miles north of Kidderminster and lies on the River Stour and the Staffordshire and Worcestershire Canal. At the time of the 2001 census, it had a population of 2,096. Notable features There are 13 Listed Buildings within Wolverley, three of which are grade II*. One of the unusual features of the area are rooms cut into the sandstone cliffs behind some of the houses. In the centre of the village, next to the Queen's Head Public House car-park are some caves which reflect this usage. Wolverley has one of the few remaining animal pounds in the area. St. John's Church Woverley's Church of England and parish church is dedicated to St. John. It is claimed as a tradition that there has been a church or chapel on the site since Anglo-Saxon times. The first documented evidence of a church was the mention of a parish priest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tin Can
A steel can, tin can, tin (especially in British English, Australian English, Canadian English and South African English), steel packaging, or can is a container for the distribution or storage of goods, made of thin metal. Many cans require opening by cutting the "end" open; others have removable covers. They can store a broad variety of contents: food, beverages, oil, chemicals, etc. Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some dialects, even aluminium cans are called "tin cans". Steel cans are highly recyclable, unlike materials like plastic, with around 65% of steel cans being recycled. History The tin canning process was conceived by the Frenchman Philippe de Girard, who got a British merchant Peter Durand to patent the idea in 1810. The canning concept was based on experimental food preservation work in glass containers the year before by the French inventor Nicholas Appert. Durand did not pursue food canning, but, in 1812, ...

Sheet Metal
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous ( iron-based) metals and nonferrous metals such as aluminum or copper. Cop ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontypool
Pontypool ( cy, Pont-y-pŵl ) is a town and the administrative centre of the county borough of Torfaen, within the historic boundaries of Monmouthshire in South Wales. It has a population of 28,970. Location It is situated on the Afon Lwyd river in the county borough of Torfaen. Located at the eastern edge of the South Wales coalfields, Pontypool grew around industries including iron and steel production, coal mining and the growth of the railways. A rather artistic manufacturing industry which also flourished here alongside heavy industry was Japanning, a type of lacquer ware. Pontypool itself consists of several smaller districts, these include Abersychan, Cwmffrwdoer, Pontnewynydd, Trevethin, Penygarn, Wainfelin, Tranch, Brynwern, Pontymoile, Blaendare, Cwmynyscoy, New Inn, Griffithstown and Sebastopol. History The name of the town in Welsh – ''Pont-y-pŵl'' – originates from a bridge ('pont') associated with a pool in the Afon Lwyd. The Welsh word ''pŵl'' is a ...

Dud Dudley
Dudd (Dud) Dudley (1600–1684) was an English metallurgist, who fought on the Royalist side in the English Civil War as a soldier, military engineer, and supplier of munitions. He was one of the first Englishmen to smelt iron ore using coke. Background and early life Dudley was the illegitimate son of Edward Sutton, 5th Baron Dudley of Dudley Castle. Dudd was the fourth of Lord Dudley's eleven children by his 'concubine' Elizabeth, the daughter of William Tomlinson (she died 3 July 1629). Strictly, he was called Dudd Dudley otherwise Tomlinson. His eldest brother was Robert Dudley of Netherton Hall. Dudd married Eleanor Heaton, (1606–1675), on 12 October 1626, at St. Helen's Church, Worcester. Lord Dudley (though he had a legitimate son, and a granddaughter by him, as well as four legitimate daughters and numerous grandchildren) seemed to have attended to the up-bringing of his natural children by Elizabeth Tomlinson; he educated and provided for them. On the other hand, he f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Finery Forge
A finery forge is a forge used to produce wrought iron from pig iron by decarburization in a process called "fining" which involved liquifying cast iron in a fining hearth and removing carbon from the molten cast iron through oxidation. Finery forges were used as early as the 3rd century BC in China. The finery forge process was replaced by the puddling process and the roller mill, both developed by Henry Cort in 1783–4, but not becoming widespread until after 1800. History A finery forge was used to refine wrought iron at least by the 3rd century BC in ancient China, based on the earliest archaeological specimens of cast and pig iron fined into wrought iron and steel found at the early Han Dynasty (202 BC – 220 AD) site at Tieshengguo.Pigott, Vincent C. (1999). ''The Archaeometallurgy of the Asian Old World''. Philadelphia: University of Pennsylvania Museum of Archaeology and Anthropology. , p. 186-187. Pigott speculates that the finery forge existed in the previous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironmaster
An ironmaster is the manager, and usually owner, of a forge or blast furnace for the processing of iron. It is a term mainly associated with the period of the Industrial Revolution, especially in Great Britain. The ironmaster was usually a large scale entrepreneur and thus an important member of a community. He would have a large country house or mansion as his residence. The organization of operations surrounding the smelting, refining and casting of iron was labour-intensive, and so there would be numerous workers reliant on the furnace works. There were ironmasters (possibly not called such) from the 17th century onwards, but they became more prominent with the great expansion in the British iron industry during the Industrial Revolution. 17th century ironmasters (examples) An early ironmaster was John Winter (Royalist), John Winter (about 1600–1676) who owned substantial holdings in the Forest of Dean. During the English Civil War he cast cannons for Charles I of England ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frying Pan
A frying pan, frypan, or skillet is a flat-bottomed pan used for frying, searing, and browning foods. It is typically in diameter with relatively low sides that flare outwards, a long handle, and no lid. Larger pans may have a small grab handle opposite the main handle. A pan of similar dimensions, but with less flared, more vertical sides and often with a lid, is called a sauté pan. While a sauté pan can be used as a frying pan, it is designed for lower heat cooking. History Copper frying pans were used in ancient Mesopotamia. Frying pans were also known in ancient Greece where they were called ''tagēnon'' (Greek: τάγηνον) and Rome, where they were called ''patella'' or ''sartago''. The word ''pan'' derives from the Old English ''panna''. Before the introduction of the kitchen stove in the mid-19th century, a commonly used cast-iron cooking pan called a 'spider' had a handle and three legs used to stand up in the coals and ashes of the fire. Cooking pots a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slitting Mill
The slitting mill was a watermill for slitting bars of iron into rods. The rods then were passed to nailers who made the rods into nails, by giving them a point and head. The slitting mill was probably invented near Liège in what is now Belgium. The first slitting mill in England was built at Dartford, Kent in 1590. This was followed by one near Rugeley at the once separate village which was called Stonehouse, but now called Slitting Mill, by about 1611, and then Hyde Mill in Kinver in 1627. Others followed in various parts of England where iron was made. However, there was a particular concentration of them on the River Stour between Stourbridge and Stourport, where they were conveniently placed to slit iron that was brought up (or down) the River Severn before it reached nailers in the Black Country. The slitting mill consisted of two pairs of rollers turned by water wheels. Mill bars were flat bars of iron about three inches (75 mm) wide and half an inch (13&nb ...
