primary extraction is the initial phase (the first few millimeters) of the extraction of a spent casing from the firearm chamber. After the primary extraction...

industries are, along with agriculture, the basis of the primary sector of the economy. Extraction produces raw material, which is then processed to add...

Root extraction, in mathematics, the computation of a nth root Extraction (chemistry), the separation of a substance from a matrix Primary extraction, the...

little or no mechanical leverage in order to aid in chambering and primary extraction, as opposed to a traditional turn-bolt action. List of weapons List...

where the user has to manually rotate the bolt for chambering and primary extraction. A straight-pull mechanism is also distinct from lever action and...

often classified according to the three-sector theory into sectors: primary (extraction and agriculture), secondary (manufacturing), and tertiary (services)...

the Blaser R93 and R8 have been reported to have no issues with primary extraction. The bolt head moves in a purely linear motion, and except for the...

from the upper to the lower parts where well extraction is located. Recovery factor during the primary recovery stage is typically 5-15%. When the underground...

The primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, logging, fishing,...

shooting before World War I, but the close chamber tolerances, lack of primary extraction and length made the Mk.III (or "1910") Ross rifle unsuitable for the...

Vacuum extraction (VE), also known as ventouse, is a method to assist delivery of a baby using a vacuum device. It is used in the second stage of labor...

[citation needed] The locking lugs are angled slightly to aid with primary extraction. The rifle was delivered with a traditional slim wooden stock where...

Copper extraction is the multi-stage process of obtaining copper from its ores. The conversion of copper ores consists of a series of physical, chemical...

bolt in addition to the linear motions to perform chambering and primary extraction. The bolt locking of a straight pull action is achieved differently...

A dental extraction (also referred to as tooth extraction, exodontia, exodontics, or informally, tooth pulling) is the removal of teeth from the dental...

bolt is rotating to unlock, bolt face is slowly moving back, giving primary extraction of the case. Similar feature can be seen on MG 30, MG 15, MG 17 and...

operation was violent and often resulted in poor primary extraction. To ensure a reliable extraction, the gun had an oiler on top of the receiver that...

Knowledge extraction is the creation of knowledge from structured (relational databases, XML) and unstructured (text, documents, images) sources. The resulting...

locking lugs are chamfered allowing for primary extraction upon bolt rotation which aids reliable feeding and extraction, albeit not with that much force due...

workflow. Usually, the term data extraction is applied when (experimental) data is first imported into a computer from primary sources, like measuring or recording...

mechanical advantage used during chambering and primary extraction, which makes for more reliable feeding and extraction. Both types of mechanisms have won championships...

Sedimentary Basin. Steam-assisted gravity drainage is one of the two primary extraction techniques in Alberta's oil sands, the other being strip-mining. While...

piece swings up and this movement provides the leverage required for primary extraction. The breech block is then carried rearwards extracting the empty cartridge...

Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3600 tons annually, and...

offers no primary extraction upon bolt rotation, the 5.45×39mm AK-74 bolt has a larger extractor claw than the 7.62×39mm AKM for increased extraction reliability...

counter-clockwise to unlock. The locking lugs have no pitch therefore no primary extraction occurs during the unlocking sequence. A deeply seated spring-loaded...

this gives a mechanical advantage to the system and accomplishes primary extraction of the spent casing from the chamber. The result of this is that the...

Note that severance taxes are used in jurisdictions where most resource extraction occurs on privately owned land and/or where sub-surface minerals are privately...
