Hiram Percy Maxim
Hiram Percy Maxim (September 2, 1869 – February 17, 1936) was an American radio pioneer and inventor, and co-founder (with Clarence D. Tuska) of the American Radio Relay League (ARRL). Hiram Percy Maxim is credited with inventing and selling the first commercially successful firearm silencer, and also with developing mufflers for internal combustion engines. Early years He was the son of Sir Hiram Maxim, inventor of the Maxim Machine gun. He was the nephew of Hudson Maxim, an inventor of explosives and ballistic propellants. He had two sisters, Florence Maxim, who married George Albert Cutter, and Adelaide Maxim, who married Eldon Joubert, Ignace Paderewski's piano tuner. In 1875, the family moved from Brooklyn, New York to Fanwood, New Jersey, with his father joining the rest of the family on weekends. At age 17, Hiram was a mechanical engineering graduate, class of 1886, of the Massachusetts Institute of Technology (then a two-year course). He went to work for various ...

La Junta, Colorado
La Junta is a home rule municipality in , the county seat of, and the most populous municipality of Otero County, Colorado, United States. The city population was 7,322 at the 2020 United States Census. La Junta is located on the Arkansas River in southeastern Colorado east of Pueblo. History La Junta (Spanish for "the junction") was named for the fact it rested at the intersection of the Santa Fe Trail and a pioneer road to Pueblo. The town developed near Bent's Fort, a fur trading post of the 19th century. During World War II, La Junta had an Army Air Force Training Base outside town. An Air Force detachment of the Strategic Air Command remained there until modern flight simulators developed in the 1980s rendered live flight unnecessary for pilot training maneuvers. At least one military aircraft crashed close by during such training maneuvers. Geography and climate The area is high plains terrain, dry with short grass prairie and sagebrush, and is part of the Sou ...

Karl Benz
Carl Friedrich Benz (; 25 November 1844 – 4 April 1929), sometimes also Karl Friedrich Benz, was a German engine designer and automotive engineer. His Benz Patent Motorcar from 1885 is considered the first practical modern automobile and first car put into series production. He received a patent for the motorcar in 1886. His company Benz & Cie., based in Mannheim, was the world's first automobile plant and largest of its day. In 1926 it merged with Daimler Motoren Gesellschaft to form Daimler-Benz which produces the Mercedes-Benz among other brands. Benz is widely regarded as "the father of the car" and "father of the automobile industry".

ARRL
The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the United States. ARRL is a non-profit organization, and was co-founded on April 6, 1914, by Hiram Percy Maxim and Clarence D. Tuska of Hartford, Connecticut. The ARRL represents the interests of amateur radio operators before federal regulatory bodies, provides technical advice and assistance to amateur radio enthusiasts, supports a number of educational programs and sponsors emergency communications service throughout the country. The ARRL has approximately 161,000 members. In addition to members in the US, the organization claims over 7,000 members in other countries. The ARRL publishes many books and a monthly membership journal called '' QST''. The ARRL is the primary representative organization of amateur radio operators to the US government. It performs this function by lobbying the US Congress and the Federal Communications Commission. The ARRL is also the intern ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high- pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engi ...

Muffler
A muffler (North American and Australian English) or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an automobile. Description Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting. The noise of the burning-hot exhaust gas exiting the engine at high speed is abated by a series of passages and chambers lined with roving fiberglass insulation and/or resonating chambers harmonically tuned to cause destructive interference, wherein opposite sound waves cancel each other out. An unavoidable side effect of this noise reduction is the restriction of the exhaust gas flow, which creates back pressure, which can decrease engine efficiency. This is because the engine exh ...

Suppressor
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report (sound of a gunshot) and muzzle rise when a gun (firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muzzle and hence suppressing the muzzle blast. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder containing internal sound baffles, with a hollow bore to allow the projectile (bullet) to exit normally. During firing, the bullet flies through the bore with little hindrance, but most of the expanding gas ejecta behind it is retained through a longer and convoluted escape path created by the baffles, prolonging the release time. This slows down the gas and dissipates its kinetic energy into a larger surface area, reduci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph McCarthy
Joseph Raymond McCarthy (November 14, 1908 – May 2, 1957) was an American politician who served as a Republican United States Senate, U.S. Senator from the state of Wisconsin from 1947 until his death in 1957. Beginning in 1950, McCarthy became the most visible public face of a period in the United States in which Cold War tensions fueled fears of widespread Communism, communist Subversion (politics), subversion. He is known for alleging that numerous communists and Soviet Union, Soviet spies and sympathizers had infiltrated the United States federal government, universities, film industry, and elsewhere. Ultimately, he was censured for refusing to cooperate with, and abusing members of, the committee established to investigate whether or not he should be censured. The term "McCarthyism", coined in 1950 in reference to McCarthy's practices, was soon applied to similar anti-communism, anti-communist activities. Today, the term is used more broadly to mean demagogy, demagog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
League Of Women Voters
The League of Women Voters (LWV or the League) is a nonprofit, nonpartisan political organization in the United States. Founded in 1920, its ongoing major activities include registering voters, providing voter information, and advocating for voting rights. In addition, the LWV works with partners that share its positions and supports a variety of progressive public policy positions, including campaign finance reform, health care reform, and gun control. The League was founded as the successor to the National American Woman Suffrage Association, which had led the nationwide fight for women's suffrage. The initial goals of the League were to educate women to take part in the political process and to push forward legislation of interest to women. As a nonpartisan organization, an important part of its role in American politics has been to register and inform voters, but it also lobbies for issues of importance to its members, which are selected at its biennial conventions.

Henry Hobson Richardson
Henry Hobson Richardson, FAIA (September 29, 1838 – April 27, 1886) was an American architect, best known for his work in a style that became known as Richardsonian Romanesque. Along with Louis Sullivan and Frank Lloyd Wright, Richardson is one of "the recognized trinity of American architecture". Biography Early life Richardson was born at the Priestley Plantation in St. James Parish, Louisiana, and spent part of his childhood in New Orleans, where his family lived on Julia Row in a red brick house designed by the architect Alexander T. Wood. He was the great-grandson of inventor and philosopher Joseph Priestley, who is usually credited with the discovery of oxygen. Richardson went on to study at Harvard College and Tulane University. Initially, he was interested in civil engineering, but shifted to architecture, which led him to go to Paris in 1860 to attend the famed École des Beaux Arts in the atelier of Louis-Jules André. He was only the second U.S. citizen to atten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
