Stielhandgranate
is the German term for " stick hand grenade" and generally refers to a prominent series of World War I and World War II–era German stick grenade designs, distinguished by their long wooden handles, pull cord arming and cylindrical warheads. The first models were introduced by the Imperial German Army during World War I and the final design was introduced during World War II by the German Wehrmacht. The distinctive appearance of the ''Stielhandgranate'' family has led to them being called "potato mashers" in British Army slang, and they remain one of the most easily recognized infantry weapons of the 20th century. World War I models: 1915–1917 Germany entered World War I with a single grenade type: a heavy ball-shaped fragmentation grenade ('' Kugelhandgranate'') for use only by pioneers in attacking fortifications. It was too heavy for regular battlefield use by untrained troops and not suitable for mass production. This left Germany without a standard- ...

Stick Hand Grenade
A grenade is a small explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, an arming safety secured by a transport safety. The user removes the transport safety before throwing, and once the grenade leaves the hand the arming safety gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive, anti-tank and stun grenades), chemical aerosols (smoke, gas and chemical grenades) or fire (incendiary grenades). Their outer casings, generally made of a hard synthetic material or steel, are desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Potato Masher
A potato masher, tater masher, bean masher, pea masher, masher, or crusher is a food preparation utensil used to crush soft food for such dishes as mashed potatoes, Retrieved November 2016 apple sauce, or refried beans. Potatoes mashed using a potato masher tend to be fluffier and lighter in texture compared to other methods of mashing, because use of the device reduces cell damage to the potato, releasing less potato starch, starch. Construction The potato masher consists of an upright or sideways handle connected to a mashing head. The head is most often a large-gauge wire in a rounded zig-zag shape, or a plate with holes or slits. The term 'potato masher' first appeared in the diaries of keen potato breeder Lord Timothy George II of Cornwall, in 1813. Basic designs made from a single piece of wood were used in Victorian times, before the more complex modern designs which are now used. This type of wooden masher, which is effectively a large wooden Mortar and pestle, pestle, is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mills Bomb
"Mills bomb" is the popular name for a series of British hand grenades which were designed by William Mills. They were the first modern fragmentation grenades used by the British Army and saw widespread use in the First and Second World Wars. Development William Mills, a hand grenade designer from Sunderland, patented, developed and manufactured the "Mills bomb" at the Mills Munitions Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland, who later engaged in a patent lawsuit. Col. Arthur Morrow, a New Zealand Wars officer, also believed aspects of his patent were incorporated into the Mills Bomb. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915 as the No. 5. The Mills bomb underwent numerous modifications. The No. 23 was a No. 5 with a rodded base plug which allowed it to be fired from a rifle. This concept evolved further with the No. 36, a variant with a detachable bas ...

Stielgranate 41
The 41 (German: "stick grenade"; model 1941), also known as 3.7 cm Aufsteck Geschoss, was a German shaped charge, fin-stabilized shell, used with the 3.7 cm Pak 36 anti-tank gun to give it better anti-tank performance. Background The 3.7 cm PaK 36, was the standard anti-tank gun of the Wehrmacht in 1940. A sound design, it was copied by other nations, and while its penetration was somewhat disappointing, the gun mobility more than compensated for its defects. Once it became clear that the newest Allied tanks could shrug off even direct hits from the PaK 36 by late 1940, the Germans began developing an unusual spigot bomb in order to give the Pak 36 a chance of destroying enemy tanks, specially since more than 20,000 guns were issued by mid-1941. The Stielgranate 41 was also seen as a way of alleviating the shortages of the heavier 5 cm Pak 38 and 7.5 cm Pak 40 anti-tank guns. Design The Stielgranate 41 looked like a rifle grenade, only considerably larger. One part of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ammonal
Ammonal is an explosive made up of ammonium nitrate and aluminium powder. TNT is added to create T-ammonal which improves properties such as brisance. The mixture is often referred to as Tannerite, which is a brand of ammonal. The ammonium nitrate functions as an oxidizer and the aluminium as fuel. The use of the relatively cheap ammonium nitrate and aluminium makes it a replacement for pure TNT. The mixture is affected by humidity because ammonium nitrate is highly hygroscopic. Ammonal's ease of detonation depends on fuel and oxidizer ratios, 95:5 ammonium nitrate and aluminium being fairly sensitive, however not very oxygen balanced. Even copper metal traces are known to sensitize bulk amounts of ammonium nitrate and further increase danger of spontaneous detonation during a fire, most likely due to the formation of tetramines. More oxygen balanced mixtures are not easily detonated, requiring a fairly substantial shock, though it remains more sensitive than trinitrotolue ...

Trinitrotoluene
Troponin T (shortened TnT or TropT) is a part of the troponin complex, which are proteins integral to the contraction of skeletal and heart muscles. They are expressed in skeletal and cardiac myocytes. Troponin T binds to tropomyosin and helps position it on actin, and together with the rest of the troponin complex, modulates contraction of striated muscle. The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. It was discovered by the German physician Hugo A. Katus at the University of Heidelberg, who also developed the troponin T assay. Subtypes * Slow skeletal troponin T1, TNNT1 (19q13.4, ) * Cardiac troponin T2, TNNT2 (1q32, ) * Fast skeletal troponin T3, TNNT3 (11p15.5, ) Reference values The 99th percentile cutoff for cardiac troponin T (cTnT) is 0.01 ng/mL. The reference range for the high sensitivity troponin T is a normal 52 ng/L. Backgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
War Office
The War Office has referred to several British government organisations throughout history, all relating to the army. It was a department of the British Government responsible for the administration of the British Army between 1857 and 1964, at which point its functions were transferred to the new Ministry of Defence (United Kingdom), Ministry of Defence (MoD). This article contains text from this source, which is available under th Open Government Licence v3.0 © Crown copyright It was equivalent to the Admiralty (United Kingdom), Admiralty at that time, which was responsible for the Royal Navy (RN), and (much later) the Air Ministry, which oversaw the Royal Air Force (RAF). The name 'Old War Office' is also given to the former home of the department, located at the junction of Horse Guards Avenue and Whitehall in central London. The landmark building was sold on 1 March 2016 by HM Government for more than British pound, £350 million, on a 250-year lease for conversion int ...

F1 Grenade (France)
The F-1 grenade is a hand grenade mass-produced by France during and after WW1, used en masse in the majority of European countries throughout the First and Second World Wars. Overview The F-1 grenade was first put into mass production by the French State in 1915 during the First World War. In May 1915 the first of the F1 grenades (fusante No. 1) appeared in the French military, in limited quantities. This new weapon inherited from the experience of the first months of the war: the shape was made to be more modern, with an external grooves pattern for better grip and easier fragmentation. The second expectation proved deceptive, since the explosion in practice gave no more than 10 fragments (although the pattern was designed to split into all the 38 drawn divisions). The design was proved to be very functional, especially due to its stability compared to other grenades of the same period. Later, the Fusante No. 1 was used ''en masse'' by many foreign armies in the period 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mk 2 Grenade
The Mk 2 grenade (initially known as the Mk II), also nicknamed the Pineapple is a fragmentation-type anti-personnel hand grenade introduced by the U.S. armed forces in 1918. It was the standard issue anti-personnel grenade used during World War II, and also saw limited service in later conflicts, including the Korean War and Vietnam War. Replacing the failed Mk 1 grenade of 1917, it was standardized in 1920 as the Mk II, and redesignated the Mk 2 on 2 April 1945. The Mk 2 was gradually phased out of service as the M26-series (M26/M61/M57) grenade was introduced during the Korean War. Due to the tremendous quantity manufactured during World War II the Mk 2 was still in limited issue with the US Army and US Marine Corps throughout the 1950s and 1960s. The U.S. Navy was one of the last users of the Mk 2 when it was finally withdrawn from U.S. military service in 1969, replaced with the M33 series (M33/M67). Description The Mk 2 grenade did not widely replace the failed Mk 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

F1 Grenade (Russia)
The Soviet F-1 hand grenade (Russian: Фугасный > ''Fugasnyy 1'', "Explosive, Type No. 1") is an anti-personnel fragmentation defensive grenade. It is based on the French F1 grenade and contains a explosive charge ( TNT). The total weight of the grenade with the fuze is about . Due to its shape and its yellow-green color, it is nicknamed the (fem. 'little lemon'). It is also nicknamed ''Efka'' () for the letter F. It is similar to the American Mk 2 "pineapple grenade", which was also ultimately modeled on the French F-1. F-1 simulation-training grenade is called УРГ (учебная ручная граната), URG (training hand grenade). Fuse The ''Universal'nyi Zapal, Ruchnaya Granata, Modernizirovannyi'' (UZRGM) (Russian for 'universal igniter, hand grenade, improved') fuse is a universal Russian type also used in the RG-42 and RGD-5 grenades. The standard time delay for this fuse is 3.5 to 4 seconds. There was a myth originating from an article written b ...
