The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes.
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed, and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.
The slide on the majority of fully/semi-automatic pistols is the upper part that reciprocates ("slides") with recoil during the gun's operating cycle. It serves as the bolt carrier group (BCG) and partly as the receiver, and generally houses the firing pin/striker, the extractor and frequently also the barrel, and provides a mounting platform for iron and optical sights.
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The Desert Eagle or simply Deagle is a single-action, gas-operated, semi-automatic pistol capable of chambering the .50 Action Express, the largest centerfire cartridge of any magazine-fed, self-loading pistol and famous for other large caliber chamberings.
A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect.
An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow.
A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms "breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section.
The Colt Detective Special is a six-shot, carbon steel framed, 2-inch (5.1 cm) or 3-inch (7.6 cm) barreled, double-action revolver, and the first example of a class of firearms known as "snubnose revolvers". Made by Colt's Manufacturing Company, this model revolver, as the name "Detective Special" suggests, was intended to be a concealed weapon used by plainclothes police detectives.
The Colt Trooper is a medium frame, double-action revolver featuring a six-round cylinder, chambered for .22 Long Rifle, .22 Winchester Magnum Rimfire, .38 Special, and .357 Magnum caliber cartridges. Designed as a less expensive alternative to the upscale Colt .357 and the later Colt Python and Colt King Cobra, it was marketed to law enforcement agencies as well as civilians.
The Rast & Gasser Model 1898 was a service revolver used by the Austro-Hungarian Army during World War I and various armies in World War II.
The Colt Model 1889 was a revolver produced by the Colt Manufacturing Company in the late 19th to the early 20th century.
A firearm malfunction is the failure of a firearm to operate as intended for causes other than user error. Malfunctions range from temporary and relatively safe situations, such as a casing that did not eject, to potentially dangerous occurrences that may permanently damage the gun and cause injury or death. Improper handling of certain types of malfunctions can be very dangerous. Following gun safety rules can prevent firearm malfunctions, and limit the damage inflicted by them if they do occur. Proper cleaning and maintenance of a firearm play a big role in preventing malfunctions.
The Ruger SR1911 is a semi-automatic pistol modeled after the classic Colt M1911 pistol.
The Colt House Revolver was one of the first metallic cartridge rear-loading revolvers to be produced by the Colt's Patent Fire Arms Manufacturing Company, in 1871. The same year, Colt's also patented the Colt Open Top, another metallic cartridge rear-loader, but in fact the Open Top production didn't start until 1872, although a pocket version of the Open Top, a completely different design, went on sales as of 1871, the Colt Open Top Pocket Model Revolver.
The Hi-Point Model CF-380 is a polymer-framed, semi-automatic, blowback-operated pistol manufactured by Hi-Point Firearms. It is chambered in .380 ACP.
Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity.
The Röhm RG-14 is a double-action, six-shot revolver chambered in .22, formerly manufactured and sold by Röhm Gesellschaft of Sontheim/Brenz, Germany. It is notable for being the model of firearm used by John Hinckley Jr. to shoot Ronald Reagan on 30 March 1981. Until 1968, the guns were manufactured in Germany. The Gun Control Act of 1968 prevented their import unto the US, so subsequently they were manufactured at a Röhm factory in Miami.
The Kel-Tec RDB is a bullpup carbine offered in 5.56×45mm NATO semi-automatic rifle, manufactured by Kel-Tec Industries of Florida. It uses a rotary bolt with a spring loaded ejector and an extractor facing down, ejecting spent shell casings downward, allowing easy ambidextrous use.
Flight Lieutenant Sean Cunningham was a Royal Air Force pilot on the Red Arrows aerobatics display team, who died when his ejection seat initiated whilst the aircraft he was in was stationary on the ground and he was conducting pre-flight checks. The incident occurred at the Red Arrows' home base, RAF Scampton in Lincolnshire, England. The initiation of the ejection seat was assumed to be by accident. The parachute on the seat did not deploy and Cunningham fell, still strapped to the seat, 220 feet (67 m) to his death 217 feet (66 m) away from the motionless aircraft. In January 2018, in the prosecution brought by the Health and Safety Executive, Martin-Baker, the manufacturers of the seat, pleaded guilty to a breach of health and safety law regarding Cunningham's death. On 23 February 2018, Martin-Baker were fined £1.1 million.
