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 Valentines were produced in eleven marks, plus specialised variants, accounting for about a quarter of wartime British tank production. The variants included riveted and welded construction, petrol and diesel engines and increases in armament. It was supplied in large numbers to the USSR and built under licence in Canada. It was used by the British in the North African campaign. Developed by Vickers, it proved to be 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. White notes that "incidentally" Valentine was the middle name of Sir John Carden, 6th Baronet, Sir John Carden, the man responsible ...

Patriot Park
Patriot Park () is a theme park in Kubinka, Russia, that is themed around equipment of the Russian military and the Soviet Union's victory in World War II. The park, which officially opened in 2016, is designed around a military theme, and includes interactive exhibits with military equipment (including a mini-Reichstag building, Reichstag to storm). The concept and management of Patriot Park changed frequently. The exhibits of the tank museum were located in 7 powerful Soviet pavilions by armored vehicles category in progress, so that specialists could see the development. Initially, only 14 light summer hangars were installed in Patriot Park. One hangar housed armored vehicles of the Second World War of all countries, corresponding to a given period: 1941, 1942, 1943, 1944-45. This roughly corresponded to the "Battle of Moscow", "Battle of Stalingrad", "Battle of Kursk" and "Battle of Berlin". One hangar was dedicated to military space, another to airborne armored vehicles. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline Engine
A petrol engine (gasoline engine in American and Canadian 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 Autogas, liquefied petroleum gas and Common ethanol fuel mixtures, ethanol blends (such as ''E10 petrol, E10'' and ''Common ethanol fuel mixtures#E85, E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use Spark-ignition engine, spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus Otto, Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873.

Acronym
An acronym is a type of abbreviation consisting of a phrase whose only pronounced elements are the initial letters or initial sounds of words inside that phrase. Acronyms are often spelled with the initial Letter (alphabet), letter of each word in all caps with no punctuation. For some, an initialism or alphabetism connotes this general meaning, and an ''acronym'' is a subset with a narrower definition; an acronym is pronounced as a word rather than as a sequence of letters. In this sense, ''NASA'' () is an acronym, but ''United States, USA'' () is not. The broader sense of ''acronym'', ignoring pronunciation, is its original meaning and in common use. . Dictionary and style-guide editors dispute whether the term ''acronym'' can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym space (punctuation), spacing, letter case, casing, and punctuation. The phrase that the acronym stands for is called its . The of an acron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ran a company from 1914 to 1916 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 two-seat fibreboard body. Carden even sold one of these to King Alfonso XIII of Spain before s ...

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 a martyr named Valentine, and through later folk traditions it has also 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 Saint 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: tradition maintains that Saint Valentine performed weddings for Christian soldiers who were forbidden to marry by the Roman emperor; an 18th-century embellishment to the legen ...

Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacturer, aircraft manufacture and opened a flying school.

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylinder (geometry), cylindrical shaft with a head on one end. The end opposite the head is called the ''tail''. On installation, 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 (physics), tension loads. However, it is much more capable of supporting Shear force, shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term ''rivet'' was introduced and, where they are remembered, are usually classified among nails and bolts respectively. History Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archeology, archaeological findings dating back to the Bronze Age. Rivet ...

Infantry Tank
The infantry tank was a tank 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 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 or light tanks were expected to use their higher speed and longer range to operate far behind the front and cut 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 which replaced both the Churchill and any medium or cruiser tanks then in service. ...
