Semi-automatic Rifles Of The Soviet Union
Semi-automatic - ''Noun'': "Partially automatic and partially manual in operation (i.e., operated both automatically and manually, by hand); not ''fully-automatic''." This may refer to: * A semi-automatic firearm, a firearm which automatically loads the next round, but will only fire one round per trigger pull ** Semi-automatic rifle ** Semi-automatic pistol ** Semi-automatic shotgun * Semiautomatic switching system, a term used in telecommunication * Semi-automatic transmission: a manual transmission with an automated clutch (i.e., no physical clutch pedal), but the driver is still required to shift gears manually, by hand. Also called: ''clutchless manual transmission'' or ''automated manual transmission''. * "Semi-Automatic", a song from Twenty One Pilots' 2013 album '' Vessel'' [Baidu] |
Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Semi-automatic Rifle
A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger, and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. For comparison, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released. History The first design of a recoil-operated semi-automatic rifle is attributed to Ferdinand Mannlicher, who unveiled the design in 1885 based on work begun in 1883. Other non-gas operated semi-automatic models were the Model 85 and Mannlicher Models 91, 93 and 95 rifles. The designs were deeply flawed and never made past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77), such as insufficient velocity and excessive fouling; automatic firearms would only become feasible after smoke ...

Semi-automatic Pistol
A semi-automatic pistol is a type of repeating single-chamber handgun ( pistol) that automatically cycles its action to insert the subsequent cartridge into the chamber (self-loading), but requires manual actuation of the trigger to actually discharge the following shot. As a result, only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/ striker until the trigger has been released and reset. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol (E.G.: Automatic Colt Pistol). A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer/s ...

Semi-automatic Shotgun
A semi-automatic shotgun is a repeating shotgun with a semi-automatic action, i.e. capable of automatically chambering a new shell after each firing, but requires individual trigger-pull to manually actuate each shot. Semi-automatic shotguns use gas-, blowback or recoil operation to cycle the action, eject the empty shell, and load another round. Many semi-automatic shotguns also provide an optional manual means of operation such as by pump action or a charging handle. Examples Notable semi-automatic shotguns include: *Akdal MKA 1919 * Armsel Striker-12 *Baikal MP-153 *Benelli M1014 *Beretta 1301 * Beretta AL391 *Beretta Xtrema 2 *Browning Auto-5 *Daewoo USAS-12 * Franchi Special Purpose Shotgun 12 *Franchi SPAS-15 *High Standard Model 10 *Ithaca Mag-10 *IWI Tavor TS12 *Mossberg 9200 *Mossberg 930 *Remington Model 1100 *Remington Model 11-87 *Remington Model SP-10 *Saiga-12 ("''Сайга-12''") *Sjögren shotgun * Smith & Wesson Model 1000 *SRM Arms Model 1216 *Vepr-12 * ...

Semiautomatic Switching System
In telecommunication, the term semiautomatic switching system has the following meanings: #In telephone systems, a switching system in which telephone operators receive call instructions orally from users and complete them by automatic equipment. #At tape relay intermediate stations, the manual routing Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone netw ... or rerouting of taped messages without rekeying them.

Semi-automatic Transmission
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo, while still requiring the driver to manually shift gears.

Stereo
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeaker A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or " ...s (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such ...
