Redcliffe Shot Tower
The Redcliffe Shot Tower was a historic shot tower in the English city of Bristol. It was the progenitor of many similar towers built around the world. The tower stood at the corner of Redcliffe Hill and Redcliffe Parade, in the suburb of Redcliffe, between the years of 1782 and 1968. In 1775, William Watts, a plumber, started converting his house, near St Mary Redcliffe Church, into the world's first shot tower, in order to make lead shot by his innovative tower process. He did this by adding a tower atop his house, and by excavating a shaft into the soft sandstone below, achieving a total drop of around . By 1782, the tower was complete and in production, and Watts was granted a patent on his process, which involved pouring molten lead through a perforated zinc pan into water below. William Watts was declared bankrupt in 1794, but his tower survived various changes of ownership until it was taken over by the Sheldon Bush and Patent Shot Company Limited in 1868. The tower re ...

Shot Tower
A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is primarily used for projectiles in shotguns, and for ballast, radiation shielding, and other applications for which small lead balls are useful. Shot making Process In a shot tower, lead is heated until molten, then dropped through a copper sieve high in the tower. The liquid lead forms tiny spherical balls by surface tension, and solidifies as it falls. The partially cooled balls are caught at the floor of the tower in a water-filled basin.. The now fully cooled balls are checked for roundness and sorted by size; those that are "out of round" are remelted. A slightly inclined table is used for checking roundness. To make larger shot sizes, a copper sieve with larger holes is used. The maximum size is limited by the height of the tower, because larger shot sizes must fall farther to solidify. A shot tower wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Buildings And Structures Demolished In 1968
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers In Bristol
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean langua ...

Bristol Harbour
Bristol Harbour is the harbour in the city of Bristol, England. The harbour covers an area of . It is the former natural tidal river Avon through the city but was made into its current form in 1809 when the tide was prevented from going out permanently. A tidal by-pass was dug for 2 miles through the fields of Bedminster for the river, known as the "River Avon New Cut", "New Cut", or simply "The Cut". It is often called the Floating Harbour as the water level remains constant and it is not affected by the state of the tide on the river in the Avon Gorge, The New Cut or the natural river southeast of Temple Meads to its source. Netham Lock at the east end of the 1809 Feeder Canal is the upstream limit of the floating harbour. Beyond the lock is a junction: on one arm the navigable River Avon continues upstream to Bath, and on the other arm is the tidal natural River Avon. The first of the floating harbour, downstream from Netham Lock to Totterdown Basin, is an artificial canal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheese Lane Shot Tower
The Cheese Lane Shot Tower is a grade II listed shot tower in the English city of Bristol. It was built in 1969, and was a replacement for an earlier shot tower, the very first such tower ever built. It now forms part of an office development called Vertigo, and is located on the north bank of the Floating Harbour upstream of Castle Park. There is no public access to the interior of the tower. History The original tower was built in 1782, in the Bristol suburb of Redcliffe, by William Watts, who is credited with the invention of the tower process for the manufacture of lead shot. It was the progenitor of many similar towers built around the world, and survived various changes of ownership until it was taken over by the Sheldon Bush and Patent Shot Company Limited in 1868. It continued in use under their ownership until 1968, when it was demolished as part of a road widening scheme. The current tower was designed as a replacement by E.N.

20th Century Road Schemes In Bristol
Road building was central to Urban planning, planning policy for much of the 20th century in Bristol, England. The planned road network evolved over time but at its core was a network of concentric Ring road, ring (or circuit) roads and high-capacity radial roads. The Inner Circuit Road formed a ring around Bristol's central area and was completed in 1970. The Outer Circuit Road was intended to form an outer ring concentric with this, but the only substantial part to be completed was the 1.3 km-long Easton Way. The two ring roads were to be complemented by 8 radial roads, some of which would follow new routes while others would be made by widening existing roads. These schemes had for the most part been abandoned by the early 1990s, and subsequently much of what was built has been decommissioned. Planning and construction The Interwar period, inter-war period was one of rapid growth in Bristol, with 22,000 private homes and 12,000 council houses being built around the city. ...

Bankrupt
Bankruptcy is a legal process through which people or other entities who cannot repay debts to creditors may seek relief from some or all of their debts. In most jurisdictions, bankruptcy is imposed by a court order, often initiated by the debtor. Bankrupt is not the only legal status that an insolvent person may have, and the term ''bankruptcy'' is therefore not a synonym for insolvency. Etymology The word ''bankruptcy'' is derived from Italian ''banca rotta'', literally meaning "broken bank". The term is often described as having originated in renaissance Italy, where there allegedly existed the tradition of smashing a banker's bench if he defaulted on payment so that the public could see that the banker, the owner of the bench, was no longer in a condition to continue his business, although some dismiss this as a false etymology. History In Ancient Greece, bankruptcy did not exist. If a man owed and he could not pay, he and his wife, children or servants were forced into ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
