Tracked Vehicle
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft Belt (mechanical), belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy Heavy equipment, construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres ...

Caterpillar Track Shingle
Caterpillars ( ) are the larva, larval stage of members of the order Lepidoptera (the Insect, insect order comprising butterfly, butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawfly, sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species herbivore, eat plant material (Folivore, often leaves), but not all; some (about 1%) insectivore, eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and Ceratophaga vastella, horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of Agriculture, agricultural Pest (organism), pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other ...

Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a Trailer (vehicle), trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanization, mechanize agricultural tasks, especially (and originally) tillage, and now many more. List of agricultural machinery, Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term "traction engine, traction motor" (1859).

Bolton-le-Moors
Bolton le Moors (also known as Bolton le Moors St Peter) was a large civil parish and ecclesiastical parish in hundred of Salford in the historic county of Lancashire, England. It was administered from St Peter's Church, Bolton in the township of Great Bolton. History Bolton le Moors was originally a part of the ancient parish of Eccles. In the 14th century it became a parish in its own right. It resembled what is now the town of Bolton and some outskirts. As with many large parishes in the north of England, it was split into townships in 1662 for easier civic administration. Some of the townships had chapels and were known as chapelries.Map of Bolton ancient parishes Retrieved on 15 March 2009. * Anglezarke * [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Moss, Greater Manchester
Red Moss is a mossland in Greater Manchester, located south of Horwich and east of Blackrod. This is a national Site of Special Scientific Interest in the United Kingdom, due to its biodiversity and undisturbed character. Pollen analysis has revealed the first peat deposits of the northwest's mosslands to be from around 8,000 years BC making Red Moss an impressive 10,000 years old. Red Moss covers an area of 47.2 hectares. A severed female head was discovered in Red Moss in the 19th century dating from the Bronze Age or early Iron Age. Bolton Metropolitan Borough Council owns most of the moss, but parts of the site are also owned by British Rail and United Utilities. History In 1999, the Wildlife Trust for Lancashire, Manchester and North Merseyside was asked to manage the area of land owned by Bolton Council with the aim of restoring suitable water levels and conditions for the growth of mossland species. Since 1999, the Trust has been undertaking large-scale capital wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodcut
Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain (unlike wood engraving, where the block is cut in the end-grain). The surface is covered with ink by rolling over the surface with an ink-covered roller ( brayer), leaving ink upon the flat surface but not in the non-printing areas. Multiple colours can be printed by keying the paper to a frame around the woodblocks (using a different block for each colour). The art of carving the woodcut can be called ''xylography'', but this is rarely used in English for images alone, although that term and ''xylographic'' are used in connection with block books, which are small books containing text ...

Tiverton (UK Parliament Constituency)
Tiverton was a United Kingdom constituencies, constituency located in Tiverton, Devon, Tiverton in east Devon, formerly represented in the House of Commons of the United Kingdom, House of Commons of England until 1707, Great Britain until 1800 and after 1801 the Parliament of the United Kingdom. Enfranchised as a parliamentary borough in 1615 and first represented in 1621, it elected two Member of Parliament (United Kingdom), Members of Parliament (MPs) by the first past the post system of election until 1885. The name was then transferred to a county constituency electing one MP. (Between 1885 and 1918, the constituency was alternatively called Devon, North East.)

John Heathcoat
John Heathcoat (7 August 1783 – 18 January 1861) was an English inventor and politician. During his apprenticeship he made an improvement to the warp-weighted loom, so as to produce mitts of a lace-like appearance. He set up his own business in Nottingham but was forced to move away to Hathern in Leicestershire, and after this new factory was attacked by former Luddites in 1816 he moved the business to Tiverton in Devon where it became most successful and established the Tiverton lace-making industry. Early life Heathcoat was born on 7 August 1783, at Duffield, Derbyshire, and was apprenticed to a frame-smith at Hathern. Career Leicestershire During his apprenticeship he made an improvement in the construction of the warp-loom, so as to produce mitts of a lace-like appearance by means of it. He began business on his own account at Nottingham, but finding himself subjected to the intrusion of competing inventors he removed to Hathern (near Loughborough) in Leicestershi ...

Józef Maria Hoene-Wroński
Józef Maria Hoene-Wroński (; ; ; 23 August 1776 – 9 August 1853) was a Polish messianist philosopher, mathematician, physicist, inventor, lawyer, occultist and economist. In mathematics, he is known for introducing a novel series expansion for a function in response to Joseph Louis Lagrange's use of infinite series. The coefficients in Wroński's new series form the Wronskian, a determinant Thomas Muir named in 1882. As an inventor, he is credited with designing some of the first caterpillar vehicles. Life and work He was born as ''Hoëné'' in 1776 but changed his name in 1815 to Józef Wroński. Later in life he changed his name to Józef Maria Hoene-Wroński, without using his family's original French spelling Hoëné. At no point in his life, neither in Polish or French, was he known as Hoëné-Wroński; nor was the common French transliteration, Josef Hoëné-Wronski, ever his official name in his native Poland (though it might have served as his chosen French ''nom ...

George Cayley
Sir George Cayley, 6th Baronet (27 December 1773 – 15 December 1857) was an English engineer, inventor, and aviator. He is one of the most important people in the history of aeronautics. Many consider him to be the first true scientific aerial investigator and the first person to understand the underlying principles and forces of flight and the creator of the wire wheel. * * * In 1799, he set forth the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation." He identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust. Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also proposed by Cayley. He constructed the first flying model aeroplane and also diagrammed the elements of vertical flight. He also designed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
