Kammerlader
The ''Kammerlader'', or "chamber loader", was the first Norwegian breech-loading rifle, and among the first breech loaders adopted for use by an armed force anywhere in the world. A single-shot black-powder rifle, the ''kammerlader'' was operated with a crank mounted on the side of the receiver. This made it much quicker and easier to load than the weapons previously used. ''Kammerladers'' quickly gained a reputation for being fast and accurate rifles, and would have been a deadly weapon against massed ranks of infantry. The ''kammerlader'' was introduced in 1842, and it is thought that about 40,000 were manufactured until about 1870. While the first flintlock breech-loading rifles, such as the Ferguson, were launched decades before 1842, Norway was among the first European countries to introduce breech loaders on a large scale throughout its army and navy. The ''kammerladers'' were manufactured in several different models, and most models were at some point modified in some wa ...

Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paper Cartridge
A paper cartridge is one of various types of small arms ammunition used before the advent of the cartridge (firearms), metallic cartridge. These cartridges consisted of a paper cylinder or cone containing the bullet, gunpowder, and in some cases, a Percussion cap, primer or a lubricant, lubricating and anti-fouling agent. Combustible cartridges are paper cartridges that use paper treated with oxidizers to allow them to burn completely upon ignition. History Paper cartridges have been in use for nearly as long as hand-held firearms, with a number of sources dating their use back to the late 14th century. Historians note their use by soldiers of Christian I, Elector of Saxony, Christian I in 1586, while the Dresden museum has evidence dating their use to 1591, and Capo Bianco writes in 1597 that paper cartridges had long been in use by Neapolitan soldiers. Their use became widespread by the 17th century. The first army to officially use paper cartridges is presumed to be "piechot ...

Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starti ...

Partial Pressure
In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas as if it alone occupied the entire volume of the original mixture at the same temperature. The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture (Dalton's Law). In respiratory physiology, the partial pressure of a dissolved gas in liquid (such as oxygen in arterial blood) is also defined as the partial pressure of that gas as it would be undissolved in gas phase yet in equilibrium with the liquid. This concept is also known as blood gas tension. In this sense, the diffusion of a gas liquid is said to be driven by differences in partial pressure (not concentration). In chemistry and thermodynamics, this concept is generalized to non-ideal gases and instead called fugacity. The partial pressure of a gas is a measure of its Thermodynamic activity, thermodynamic activity. Gases dissolve, diffuse, and react accor ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (weaponry)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a ''blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that failed t ...

Firearm Action
In firearms terminology, an action is the functional mechanism of a breechloading firearm that handles (loads, locks, fires, extracts, and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, wheellock, flintlock, and caplock). Actions can be categorized in several ways, including single action versus double action, break action versus lever-action, pump-action, bolt-action, among many other types. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of ...

Swedish Unit
Traditional Swedish units of measurement were standardized by law in 1665, prior to which they only existed as a number of related but differing local variants. The system was slightly revised in 1735. In 1855, a decimal reform was instituted that defined a new Swedish inch as Swedish foot (). Up to the middle of the 19th century, there was a law allowing the imposition of the death penalty for falsifying weights or measures. After a decision by the parliament in 1875, Sweden adopted the metric system on 22 November 1878, with a ten-year transition period until 1 January 1889. As part of the transition, the Swedish mil measurement was maintained, but was shortened from ''alnar'' – the equivalent of – to exactly . This measurement is still in use in both Sweden and Norway (which were in a union at the time). Old length units The Swedish units of length included the following: * ''aln'' – "forearm" (cf. ell) (pl. ''alnar''). After 1863, . Before that, from 1605, 59.38&nb ...

Remington M1867
The Remington M1867 is a rolling-block rifle that was produced in the second-half of the 19th century. It was the first rifle using metallic cartridges to be adopted by the Norwegian and Swedish armies. Nominally, it had a caliber of 4 decimal lines, but the actual caliber was 3.88 Norwegian decimal lines or 4.1 Swedish decimal lines (12.17 mm), and it fired a rimfire round with a 12.615 mm (.497 in) lead bullet. The 12.17 mm caliber was chosen because the Swedish army had approximately 30,000 new muzzle-loading M1860 and breech-loading M1864 rifles in 12.17 mm caliber in stock, rifles that were suitable for conversion to M1867 rolling-block rifles. With the exception of the first 10,000 rifles and 20,000 actions (for conversions of older rifles), which were made by Remington in the US, all Remington M1867 rifles and carbines were made under license in Norway and Sweden, by Kongsberg Vaapenfabrik in Norway, and by Husqvarna Vapenfabriks Aktiebolag and Carl ...

Norwegian Units Of Measure
As in the case of the Danes, the Norwegians' earliest standards of measure can be derived from their ship burials. The 60-Norwegian-feet-long Kvalsund ship (18.8 m; 61.8 ft) was built ca. 700 AD and differs from the Danish boats less than it does from the Oseberg, Gokstad and Tune ships which all date from ca. 800 AD. Thwarts are typically spaced about 3 Norwegian feet (0.94 m; 3.1 ft) apart. In 1541, an ''alen'' in Denmark and Norway was defined by law to be the Sjælland ''alen''. Subsequently, the ''alen'' was defined by law as 2 Rhine feet from 1683. From 1824, the basic unit was defined as a ''fot'' being derived from astronomy as the length of a one-second pendulum times 12/38 at a latitude of 45°. The metric system was introduced in Norway in 1875, with Norway being one of the original signatories of the meter convention. Length * ''skruppel'' – scruple, 1/12 ''linje'' or approx. 0.18 mm. * ''linje'' – line, 1/12 ''tomme'' or ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
