National Filling Factory, Banbury
National Filling Factory, Banbury, officially called National Filling Factory No. 9. was a British Ministry of Munitions filling factory, constructed during World War I and located in Banbury, Oxfordshire. The production of filled shells began in April 1916 and ended when the factory closed in 1924 Background At the outbreak of World War I, the production of explosives and the associated filling facilities for high explosives were limited to the Royal Arsenal at Woolwich, and the facilities of the Elswick Ordnance Company at Scotswood, Derwenthaugh and Lemington, Lemington Point, both close to Newcastle Upon Tyne. The British Army found itself on the Western Front (World War I), Western Front short of explosive shells and bullets. The Ministry of Munitions (MoM) under new minister David Lloyd George, were tasked to construct a suitable infrastructure of National Filling Factories (NFFs) to supply the Army. Principles of layout and operation The MoM were looking to create a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ministry Of Munitions
The Minister of Munitions was a British government position created during the First World War to oversee and co-ordinate the production and distribution of munitions for the war effort. The position was created in response to the Shell Crisis of 1915 when there was much newspaper criticism of the shortage of artillery shells and fear of sabotage. The Ministry was created by the Munitions of War Act 1915 passed on 2 July 1915 to safeguard the supply of artillery munitions. Under the very vigorous leadership of Liberal party politician David Lloyd George, the Ministry in its first year set up a system that dealt with labour disputes and fully mobilized Britain's capacity for a massive increase in the production of munitions. The government policy, according to historian J. A. R. Marriott, was that: : No private interest was to be permitted to obstruct the service, or imperil the safety, of the State. Trade Union regulations must be suspended; employers' profits must be limite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Management
Scientific management is a theory of management that analyzes and synthesizes workflows. Its main objective is improving economic efficiency, especially labor productivity. It was one of the earliest attempts to apply science to the engineering of processes in management. Scientific management is sometimes known as Taylorism after its pioneer, Frederick Winslow Taylor. Mitcham, Carl and Adam, Briggle ''Management'' in Mitcham (2005) p. 1153 Taylor began the theory's development in the United States during the 1880s and 1890s within manufacturing industries, especially steel. Its peak of influence came in the 1910s. Although Taylor died in 1915, by the 1920s scientific management was still influential but had entered into competition and syncretism with opposing or complementary ideas. Although scientific management as a distinct theory or school of thought was obsolete by the 1930s, most of its themes are still important parts of industrial engineering and management today. ...

Shrapnel Shell
Shrapnel shells were anti-personnel artillery munitions that carried many individual bullets close to a target area and then ejected them to allow them to continue along the shell's trajectory and strike targets individually. They relied almost entirely on the shell's velocity for their lethality. The munition has been obsolete since the end of World War I for anti-personnel use; high-explosive shells superseded it for that role. The functioning and principles behind shrapnel shells are fundamentally different from high-explosive shell fragmentation. Shrapnel is named after Lieutenant-General Henry Shrapnel, a Royal Artillery officer, whose experiments, initially conducted on his own time and at his own expense, culminated in the design and development of a new type of artillery shell. Usage of the term "shrapnel" has changed over time to also refer to fragmentation of the casing of shells and bombs, which is its most common modern usage and strays from the original meaning. ...

Naval Mines
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Lyddite
Picric acid is an organic compound with the formula (O2N)3C6H2OH. Its IUPAC name is 2,4,6-trinitrophenol (TNP). The name "picric" comes from (''pikros''), meaning "bitter", due to its bitter taste. It is one of the most acidic phenols. Like other strongly nitrated organic compounds, picric acid is an explosive, which is its primary use. It has also been used as medicine (antiseptic, burn treatments) and as a dye. History Picric acid was probably first mentioned in the 17th-century alchemical writings of Johann Rudolf Glauber. Initially, it was made by nitrating substances such as animal horn, silk, indigo, and natural resin, the synthesis from indigo first being performed by Peter Woulfe in 1771. The German chemist Justus von Liebig had named picric acid (rendered in French as ). Picric acid was given that name by the French chemist Jean-Baptiste Dumas in 1841. Its synthesis from phenol, and the correct determination of its formula, were accomplished during 1841. In 1799, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belfast Truss
A lattice truss bridge is a form of truss bridge that uses many small, closely spaced diagonal elements forming a lattice. The design was patented in 1820 by architect Ithiel Town. Originally a means of erecting a substantial bridge from mere planks employing lower–skilled labor, rather than heavy timbers and more expensive carpenters and equipment, the lattice truss has also been constructed using many relatively light iron or steel members. The individual elements are more easily handled by the construction workers, but the bridge also requires substantial support during construction. A simple lattice truss will transform the applied loads into a thrust, as the bridge will tend to change length under load. This is resisted by pinning the lattice members to the top and bottom chords, which are more substantial than the lattice members, but which may also be fabricated from relatively small elements rather than large beams.

Timber-framed
Timber framing () and "post-and-beam" construction are traditional methods of building with heavy Beam (structure), timbers, creating structures using squared-off and carefully fitted and Woodworking joints, joined timbers with joints secured by large wooden pegs. If the Structural system, structural frame of Load-bearing wall, load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany, where timber-framed houses are spread all over the country. The method comes from working directly from logs and trees rather than pre-cut Lumber#Dimensional lumber, dimensional lumber. Artisans or framers would gradually assemble a building by hewing logs or trees with broadaxes, adzes, and draw knife, draw knives and by using woodworking tools, such as hand-powered Brace (tool), braces and Auger (dril ...

Standard-gauge Railway
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), international gauge, UIC gauge, uniform gauge, normal gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with about 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, Uzbekistan, and some line sections in Spain. The distance between the inside edges of the heads of the rails is defined to be 1,435 mm except in the United States, Canada, and on some heritage British lines, where it is defined in U.S. customary/ British Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rail heads) to be used, as the wheels of the rolling stock (locomoti ...

Sloane Square
Sloane Square is a small hard-landscaped square on the boundaries of the central London districts of Belgravia and Chelsea, London, Chelsea, located southwest of Charing Cross, in the Royal Borough of Kensington and Chelsea. The area forms a boundary between the two largest aristocratic estates in London, the Grosvenor Estate and the Cadogan Estates, Cadogan. The square was formerly known as 'Hans Town', laid out in 1771 to a plan of by Henry Holland Snr. and Henry Holland (architect), Henry Holland Jnr. Both the square and Hans Town were named after Sir Hans Sloane (1660–1753), an Anglo-Irish people, Anglo-Irish doctor who, jointly with his appointed trustees, owned the land at the time. Location The bulk of Chelsea, especially the east end more local to Sloane Square, is architecturally and economically similar to South Kensington, Belgravia, St James's, and Mayfair. The largely retail at ground floor Kings Road with its design and interior furnishing focus intersects at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
