Syleham Windmill
Syleham Windmill was a Grade II listed post mill at Syleham, Suffolk, England which was built in 1730 at Wingfield and moved to Syleham in 1823. It was blown down on 16 October 1987. The remains of the mill survive today, comprising the roundhouse and trestle. History The mill was originally one of a pair on Wingfield Green. Both mills came into the ownership of Robert Sparkes in 1820. He believed that the mills were too close to each other and so moved one of them to Syleham in 1823. In 1839 she was owned by George Dye. He died in 1847 and the mill was purchased by John Bokenham, who sold it to John Bryant in 1848. He died in 1865 and the mill was run by his widow, Sarah until 1874 when their son James took the mill. James Bryant died in 1907 and the mill passed to his son Arthur, who installed a Ruston & Hornsby engine to drive an additional pair of millstones in the roundhouse. The mill survived a lightning strike in 1936. When Arthur Bryant died, the mill was left to his da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gristmill
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] |
Lightning Strike
A lightning strike or lightning bolt is an electric discharge between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning. A less common type of strike, ground-to-cloud (GC) lightning, is upward-propagating lightning initiated from a tall grounded object and reaching into the clouds. About 25% of all lightning events worldwide are strikes between the atmosphere and earth-bound objects. Most are intracloud (IC) lightning and cloud-to-cloud (CC), where discharges only occur high in the atmosphere. Lightning strikes the average commercial aircraft at least once a year, but modern engineering and design means this is rarely a problem. The movement of aircraft through clouds can even cause lightning strikes. A single lightning event is a "flash", which is a complex, multistage process, some parts of which are not fully understood. Most CG flashes only "strike" one physical location, referred to as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windmills In Suffolk
A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain ( gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von de ...

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 applicatio ...

Clunch
Clunch is a traditional building material of chalky limestone rock used mainly in eastern England and Normandy. Clunch distinguishes itself from archetypal forms of limestone by being softer in character when cut, such as resembling chalk in lower density, or with minor clay-like components. Use It has been used in a wide variety of shapes such as irregular lumps picked from the topsoil of certain fields, or more commonly blocks quarried by being cut from the bedrock in regular-shaped (ashlar) building blocks. If in the first form it can be bedded in a ramshackle manner (as rubble masonry); if in the second then laid in courses. In either case, mortar is often used between stones to form walls. Properties The stone is a chalk from the Lower Chalk of the Cretaceous age, the period of geological time approximately 145 – 66 million years ago. It is greyish-white to light beige in colour, often with a greenish tinge. The latter is due to the presence of glauconite, the potas ...

Suffolk County Council
Suffolk County Council is the administrative authority for the county of Suffolk, England. It is run by 75 elected county councillors representing 63 divisions. It is a member of the East of England Local Government Association. History Established in 1974 and initially based at East Suffolk County Hall, the Council relocated to Endeavour House in Ipswich in 2004. In September 2010, the council announced that it would seek to outsource a number of its services, in an attempt to cut its own budget by 30%. Controversy surrounding the then CEO Andrea Hill, some concerning including £122,000 spent on management consultants, featured in the local and national press in 2011; this led to her facing a disciplinary hearing, and subsequently resigning. Structure of the County Council The County Council is led by its CEO Nicola Beach, who has been in this role since May 2018. The Council is split into 5 distinct areas known as directorates. Each directorate has responsibility for a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 g ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millwright
A millwright is a craftsperson or skilled tradesperson who installs, dismantles, maintains, repairs, reassembles, and moves machinery in factories, power plants, and construction sites. The term ''millwright'' (also known as ''industrial mechanic'') is mainly used in the United States, Canada and South Africa to describe members belonging to a particular trade. Other countries use different terms to describe tradesmen engaging in similar activities. Related but distinct crafts include machinists, mechanics and mechanical fitters . As the name suggests, the original function of a millwright was the construction of flour mills, sawmills, paper mills and fulling mills powered by water or wind, made mostly of wood with a limited number of metal parts. Since the use of these structures originates in antiquity, millwrighting could arguably be considered one of the oldest engineering trades and the forerunner of modern mechanical engineering. In modern usage, a millwright is enga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruston & Hornsby
Ruston & Hornsby was an industrial equipment manufacturer in Lincoln, England founded in 1918. The company is best known as a manufacturer of narrow and standard gauge diesel locomotives and also of steam shovels. Other products included cars, steam locomotives and a range of internal combustion engines, and later gas turbines. It is now a subsidiary of Siemens. Background Proctor & Burton was established in 1840, operating as millwrights and engineers. It became Ruston, Proctor and Company in 1857 when Joseph Ruston joined them, acquiring limited liability status in 1899. From 1866 it built a number of four and six-coupled tank locomotives, one of which was sent to the Paris Exhibition in 1867. In 1868 it built five 0-6-0 tank engines for the Great Eastern Railway to the design of Samuel Waite Johnson. Three of these were converted to crane tanks, two of which lasted until 1952, aged eighty-four. Among the company's output were sixteen for Argentina and some for ...
