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. Underwood and Partners, a firm of str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cauldron
A cauldron (or caldron) is a large pot (kettle) for cooking or boiling over an open fire, with a lid and frequently with an arc-shaped hanger and/or integral handles or feet. There is a rich history of cauldron lore in religion, mythology, and folklore. Etymology The word cauldron is first recorded in Middle English as ''caudroun'' (13th century). It was borrowed from Norman ''caudron''T. F. Hoad, ''English Etymology'', Oxford University Press, 1993 (). p. 67. ( Picard ''caudron'', french: chaudron). It represents the phonetical evolution of Vulgar Latin ''*caldario'' for Classical Latin ''caldārium'' "hot bath", that derives from ''cal(i)dus'' "hot". The Norman-French word replaces the Old English ''ċetel'' (German ''(Koch)Kessel'' "cauldron", Dutch ''(kook)ketel'' "cauldron"), Middle English ''chetel''. The word "kettle" is a borrowing of the Old Norse variant ''ketill'' "cauldron". History Cauldrons can be found from the late Bronze Age period - vast cauldrons with ...

Towers Completed In 1969
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 language, ...

Grade II Listed Buildings In Bristol
There are many Grade II listed buildings in Bristol, United Kingdom. In England and Wales the authority for listing is granted by the Planning (Listed Buildings and Conservation Areas) Act 1990 and is administered by English Heritage, an agency of the Department for Digital, Culture, Media and Sport. In the United Kingdom the term "listed building" refers to a building or other structure officially designated as being of special architectural, historical or cultural significance. A–C D–H I–R R–Z Notes :Grid reference is based on the British national grid reference system, also known as OSGB36, and is the system used by the Ordnance Survey. :References are to the data sheets for each site oImages of Englandwhich is funded by English Heritage and the Heritage Lottery Fund, to create a 'point in time' photographic record of England's listed buildings.

Board Room
A board of directors (commonly referred simply as the board) is an executive committee that jointly supervises the activities of an organization, which can be either a for-profit or a nonprofit organization such as a business, nonprofit organization, or a government agency. The powers, duties, and responsibilities of a board of directors are determined by government regulations (including the jurisdiction's corporate law) and the organization's own constitution and by-laws. These authorities may specify the number of members of the board, how they are to be chosen, and how often they are to meet. In an organization with voting members, the board is accountable to, and may be subordinate to, the organization's full membership, which usually elect the members of the board. In a stock corporation, non-executive directors are elected by the shareholders, and the board has ultimate responsibility for the management of the corporation.

Bliemeister Method
Shot is a collective term for small spheres or pellets, often made of lead. These were the original projectiles for shotguns and are still fired primarily from shotguns and less commonly from riot guns and grenade launchers, although shot shells are available in many pistol calibers in a configuration called "birdshot", "rat-shot", or " snake shot". Lead shot is also used for a variety of other purposes such as filling cavities with dense material for weight/balance. Some versions may be plated with other metals. Lead shot was originally made by pouring molten lead through screens into water, forming what was known as "swan shot", and, later, more economically mass-produced at higher quality using a shot tower. The ''Bliemeister method'' has supplanted the shot tower method since the early 1960s. Manufacture Producing lead shot from a shot tower was pioneered in the late 18th century by William Watts of Bristol who adapted his house on Redcliffe Hill by adding a three-storey ...

Conveyor Belt
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more. Overview Conveyors are durable and reliable components used in automated distribution and warehousing, as well as manufacturing and produ ...

Elevator
An elevator or lift is a wire rope, cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or deck (building), decks of a building, watercraft, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist (device), hoist, although some pump hydraulic fluid to raise a cylindrical piston like a hydraulic jack, jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are ...

Ingot
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Precious metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars. Types Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are polycrystalline or single crystal ingots made by pulling from a molten melt. Single crystal Single crystal ingots (called boules) of materials are grown (crystal growth) using methods such as the Czo ...

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] |
