40 Mm Automatic Gun M1
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priddy's Hard
Priddy's Hard is a former military installation in Gosport, England. The site originated as a 1750s fort, and then became an armaments depot for Royal Navy and British Army weapons, explosives and other stores. The site was decommissioned in 1988, after over two hundred years of operation, with part now being developed for housing and an area retained as a museum. History Eighteenth century Priddy's Hard Fort In 1750 by an Act of King George III the Board of Ordnance purchased of agricultural land in Gosport and a boatyard from Jane Priddy and Fareham Vicar, Thomas Missing. This was to construct an earthen rampart as part of an extension of the defences of Portsmouth Harbour and the Royal Dockyard, the Gosport Lines. The ramparts were completed in 1757 and the land enclosed known to as Priddy's Hard Fort; it was manned by the Army. In the nineteenth century Priddy's Hard Fort was armed with 14 eighteen pounder guns. Proposals for a gunpowder magazine In 1764, after a series ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally " rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mo ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Binder
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in Britain) are large folders that contain file folders or hole punched papers. These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. The rings themselves come in a variety of sizes, including , though other sizes are also available. The rings are usually spring-loaded, but can also be secured by lever arch mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the early 1890s to the early 1900s. History American Henry Tillinghast Sisson invented the three ring binder, receivinpatent no. 23506on April 5, 1859. German Friedrich Soennecken invented ring binders in 1886 in Bonn. He also registered a patent on November 14, 1886, for his ''Papierlocher für Sammelmappen'' ("paper hole ...

Aktiebolaget Bofors
AB Bofors ( , , ) is a former Swedish arms manufacturer which today is part of the British arms concern BAE Systems. The name has been associated with the iron industry and artillery manufacturing for more than 350 years. History Located in Karlskoga, Sweden, the company originates from the hammer mill "Boofors", which was founded as a royal state-owned company in 1646. The modern corporate structure was created in 1873 with the foundation of Aktiebolaget (AB) Bofors-Gullspång. The Bofors Works was acquired by Johan Eberhard Geijer in 1762. It was then acquired by the latter's brother, Emanuel af Geijerstam. A leading Swedish steel producer by the early 1870s, when steel began to be used for gun manufacture in Sweden, Bofors initially sold cast and forged steel produced by the Siemens-Martin process to Finspång gun works, but soon started to expand into weapons manufacture. The company's first cannon workshop was opened in 1884. Bofors' most famous owner was Alfred Nobe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karlskoga
Karlskoga () is a locality and the seat of Karlskoga Municipality, Sweden. Located within Örebro County, 45 km (28 mi) west of Örebro, and 10 km (6 mi) north of Degerfors. With a 2020 population of 27,386 distributed over 10.55 square miles (27.33 km2), Karlskoga is the second-largest city in both Örebro County and the historical province of Värmland. Karlskoga straddles the northern shore of Lake Möckeln. Among the city's main topographical features are the two rivers, Timsälven and Svartälven. Other features include an esker, Rävåsen, contiguous with the city center. The broader Karlskoga-area differs from its bordering regions, as covered by woodlands and an uneven topography that more fitted other activities rather than agricultural practices. Karlskoga evolved around the arms manufacturer Bofors, and by 1970, it counted almost 10,000 employees. The many jobs in the arms industry during the 1900s multiplied Karlskoga's population. Today, Karlskoga is still a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bookbinding
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of ''signatures'', sheets of paper folded together into sections that are bound, along one edge, with a thick needle and strong thread. Cheaper, but less permanent, methods for binding books include loose-leaf rings, individual screw-posts (binding posts), twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack of signatures is wrapped in a flexible cover or is attached to stiffened boards. Finally, an attractive cover is placed onto the boards, which includes the publisher's information, and artistic decorations. The trade of binding books is in two parts; (i) stationery binding (vellum binding) for books intended for handwritten entries, such as accounting ledgers, business journals, blank-page books, and guest logbooks, and notebooks, manifold books, day books, diaries, and portfolios. (ii) letterpress printing and binding deals wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yugoslav Wars
The Yugoslav Wars were a series of separate but related Naimark (2003), p. xvii. ethnic conflicts, wars of independence, and insurgencies that took place in the SFR Yugoslavia from 1991 to 2001. The conflicts both led up to and resulted from the breakup of Yugoslavia, which began in mid-1991, into six independent countries matching the six entities known as republics which previously composed Yugoslavia: Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and North Macedonia (previously named ''Macedonia''). Yugoslavia's constituent republics declared independence due to unresolved tensions between ethnic minorities in the new countries, which fuelled the wars. While most of the conflicts ended through peace accords that involved full international recognition of new states, they resulted in a massive number of deaths as well as severe economic damage to the region. During the initial stages of the breakup of Yugoslavia, the Yugoslav People's Army (JNA) sought to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bofors 40 Mm Automatic Gun L/70
The Bofors 40 mm Automatic Gun L/70, (Bofors 40 mm L/70, Bofors 40 mm/70, Bofors 40/70 and the like), is a multi-purpose autocannon developed by the Swedish arms manufacturer AB Bofors (today BAE Systems Bofors) during the second half of the 1940s as a modern replacement for their extremely successful World War II-era Bofors 40 mm L/60 gun-design. It was initially intended as a dedicated anti-aircraft weapon, being sold as ''Bofors 40 mm Automatic A.A. Gun L/70'', but has since its conception been redeveloped into a dedicated multi-purpose weapon capable of firing both sabot projectiles and programmable ammunition. The Bofors 40 mm L/70 design never achieved the same popularity and historical status as the original L/60 design but has still seen great export and popularity to this day, having been adopted by around 40 different nations and even being accepted as NATO-standard in November 1953. It is still being produced and sold (since March 2005 by BA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
