P-64 (pistol)
The P-64 is a Polish semi-automatic pistol designed to fire the 9×18mm Makarov cartridge. The pistol was developed in the late 1950s at the Institute for Artillery Research (Polish: ''Zakład Broni Strzeleckiej Centralnego Badawczego Poligonu Artyleryjskiego'', which later became the Military Institute of Armament Technology, Polish: ''Wojskowy Instytut Techniczny Uzbrojenia w Zielonce''—WITU) by a team consisting of: W. Czepukajtis, R. Zimny, H. Adamczyk, M. Adamczyk, S. Kaczmarski and J. Pyzel. The P-64 is also known as the CZAK (an acronym of the designers' last names with the exception of J. Pyzel, who joined the team after the name had been established). Development The P-64 was drawn from a competition for a new service pistol issued in 1958. At the prototype stage, two versions of the CZAK pistol were created: the Model M (''Milicyjny'' - ''Police''), with a magazine capacity of 6 rounds and chambered to use the .380 ACP (9×17mm Short) cartridge and the Model W (''W ...

Polish People's Republic
The Polish People's Republic ( pl, Polska Rzeczpospolita Ludowa, PRL) was a country in Central Europe that existed from 1947 to 1989 as the predecessor of the modern Republic of Poland. With a population of approximately 37.9 million near the end of its existence, it was the second-most populous communist and Eastern Bloc country in Europe. It was also one of the main signatories of the Warsaw Pact alliance. The largest city and official capital since 1947 was Warsaw, followed by the industrial city of Łódź and cultural city of Kraków. The country was bordered by the Baltic Sea to the north, the Soviet Union to the east, Czechoslovakia to the south, and East Germany to the west. The Polish People's Republic was a socialist one-party state, with a unitary Marxist–Leninist government headed by the Polish United Workers' Party (PZPR). The country's official name was the "Republic of Poland" (') between 1947 and 1952 in accordance with the transitional Small Constitutio ...

Loaded Chamber Indicator
file:M16A2 Safety Closeup.jpg, Close-up shot of a safety of an M16 rifle, M16A2 rifle In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. Firearms with the ability to allow the user to Selective fire, select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16 rifle, M16). Some firearms manufactured after the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamping (metalworking)
Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene. Progressive dies are commonly fed from a coil of steel, coil reel for unwinding of coil to a straightener to level the coil and then into a feeder which advances the material into the press and die at a predetermined feed length. Depending on part complexity, the number of stations in the die can be determined. Stamping is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Polish Land Forces
The Land Forces () are the land forces of the Polish Armed Forces. They currently contain some 62,000 active personnel and form many components of the European Union and NATO deployments around the world. Poland's recorded military history stretches back a millennium – since the 10th century (see List of Polish wars and History of the Polish Army). Poland's modern army was formed after Poland regained independence following World War I in 1918. History 1918–1938 When Poland regained independence in 1918, it recreated its military which participated in the Polish–Soviet War of 1919–1921, and in the two smaller conflicts ( Polish–Ukrainian War (1918–1919) and the Polish–Lithuanian War (1920)).
