Valentine (tank)
The Tank, Infantry, Mk III, Valentine was an infantry tank produced in the United Kingdom during World War II. More than 8,000 of the type were produced in eleven marks, plus various specialised variants, accounting for approximately a quarter of wartime British tank production. The many variants included riveted and welded construction, petrol and diesel engines and a progressive increase in armament. It was supplied in large numbers to the USSR and built under licence in Canada. It was used extensively by the British in the North African campaign. Developed by Vickers, it proved to be both strong and reliable. Name There are several proposed explanations for the name ''Valentine''. According to the most popular one, the design was presented to the War Office on St Valentine's Day, 14 February 1940, although some sources say that the design was submitted on Valentine's Day 1938 or 10 February 1938.

Gasoline Engine
A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as ''E10'' and ''E85''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol en ...

Elswick, Tyne And Wear
Elswick ( ) is a district and electoral ward of the city and metropolitan borough of Newcastle upon Tyne, England, 1.9 miles west of the city centre, bordering the River Tyne. Historically in Northumberland, Elswick became part of Newcastle upon Tyne in 1835. Elswick is home to the Newcastle Utilita Arena; and Newcastle College, with approximately 45,000 students. History In Roman times the Vallum, a defensive barrier behind Hadrian's Wall, reached its easternmost limit in Elswick. The Wall itself carried on as far as Wallsend. The township of Elswick had originally formed part of the Barony of Bolam and was owned by Tynemouth Priory from 1120-1539, with a fishery present on the site. One of the earliest references to the coal mining industry of the north east occurs in 1330, when it was recorded that the Prior of Tynemouth let a colliery, called Heygrove, at "Elstewyke" for a rent of £5 per year. Elswick Colliery had 3 pits working from 1860 onwards. Elswick was owned by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in ''Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in ''radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like ''NASA'' and ''UNESCO''; as individual letters, like ''FBI'', ''TNT'', and ''ATM''; or as both letters and words, like '' JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary and st ...

Sir John Carden, 6th Baronet
Sir John Valentine Carden, 6th Baronet MBE (6 February 1892 – 10 December 1935) was an English tank and vehicle designer. He was the sixth baronet of Templemore, County Tipperary, from 1931. Work Born in London, Carden was a talented, self-taught engineer, with an ability to put his ideas to practical use. From 1914 to 1916, he ran a company that manufactured light passenger-cars under the brand '' Carden''. The company's first model was a cyclecar, with seating only for the driver. During the First World War, Carden served in the Army Service Corps and gained the rank of captain, acquiring experience with vehicles such as tracked Holt tractors. After the war, he returned to car manufacturing but sold his original design and factory to Ward and Avey who renamed it the AV. He then designed a new cyclecar and started manufacture at Ascot but at the end of 1919 sold the design to E. A. Tamplin who continued manufacture as the Tamplin car. A further design followed with a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Valentine's Day
Valentine's Day, also called Saint Valentine's Day or the Feast of Saint Valentine, is celebrated annually on February 14. It originated as a Christian feast day honoring one or two early Christian martyrs named Saint Valentine and, through later folk traditions, has become a significant cultural, religious, and commercial celebration of romance and love in many regions of the world. There are a number of martyrdom stories associated with various Valentines connected to February 14, including an account of the imprisonment of Saint Valentine of Rome for ministering to Christians persecuted under the Roman Empire in the third century. According to an early tradition, Saint Valentine restored sight to the blind daughter of his jailer. Numerous later additions to the legend have better related it to the theme of love: an 18th-century embellishment to the legend claims he wrote the jailer's daughter a letter signed "Your Valentine" as a farewell before his execution; another ...

USSR
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years.

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...

Infantry Tank
The infantry tank was a concept developed by the United Kingdom and France in the years leading up to World War II. Infantry tanks were designed to support infantrymen in an attack. To achieve this, the vehicles were generally heavily vehicle armour, armoured to allow them to operate in close concert with infantry even under heavy fire. The extra armour came at the expense of speed, which was not an issue when supporting relatively slow-moving foot soldiers. Once an attack supported by infantry tanks had broken through heavily defended areas in the enemy lines, faster tanks such as cruiser tank, cruiser or light tanks were expected to use their higher speed and longer range to operate far behind the front and cut Line of communication, lines of supply and communications. The infantry tank was superseded by the "Universal Tank" concept which could adequately perform the roles of both infantry and cruiser tank, as represented by the Centurion tank, Centurion which replaced both the ...
