Elwood Haynes
Elwood Haynes (October 14, 1857 – April 13, 1925) was an American inventor, metallurgist, automotive pioneer, entrepreneur and industrialist. He invented the metal alloy stellite and independently co-discovered martensitic stainless steel along with Englishman Harry Brearley in 1912 and designed one of the earliest automobiles made in the United States. He is recognized for having created the earliest American design that was feasible for mass production and, with the Apperson brothers, he formed the first company in the United States to produce automobiles profitably. He made many advances in the automotive industry. Early in his career, while serving as a field superintendent at gas and oil companies during Indiana's gas boom, Haynes invented several devices important to the advance of the natural gas industry. When working for the Indiana Natural Gas and Oil Company, he oversaw the construction of the first long-distance natural gas pipeline in the United States, connec ...

YMCA
YMCA, sometimes regionally called the Y, is a worldwide youth organization based in Geneva, Switzerland, with more than 64 million beneficiaries in 120 countries. It was founded on 6 June 1844 by George Williams in London, originally as the Young Men's Christian Association, and aims to put Christian values into practice by developing a healthy "body, mind, and spirit". From its inception, it grew rapidly and ultimately became a worldwide movement founded on the principles of muscular Christianity. Local YMCAs deliver projects and services focused on youth development through a wide variety of youth activities, including providing athletic facilities, holding classes for a wide variety of skills, promoting Christianity, and humanitarian work. YMCA is a non-governmental federation, with each independent local YMCA affiliated with its national organization. The national organizations, in turn, are part of both an Area Alliance (Europe, Asia Pacific, the Middle East, Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trenton Gas Field
The Trenton Gas Field is located in east central Indiana and the most western portion of west central Ohio. The field was discovered in 1876, but the size and magnitude of the field was not known until the 1880s. The field was the largest natural gas discovery up to that time, with an area of , somewhat smaller in area than the state of Connecticut, containing over of natural gas. The field also contained the first giant oil reserve discovered in the United States, with an estimated of oil. The discovery led to the Indiana Gas Boom. Almost all of the natural gas was removed from the field by 1910, but only about 10% of the oil had been removed at that point. The lack of pressure caused by the removal of the gas led to a complete stoppage of oil production, even though an estimated of oil remained in the field.Gray, p. 189 Beginning in the late 20th century, oil production resumed at a slow pace after advances in artificial lift technology. Oil and gas production from this field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indiana
Indiana () is a U.S. state in the Midwestern United States. It is the 38th-largest by area and the 17th-most populous of the 50 States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th state on December 11, 1816. It is bordered by Lake Michigan to the northwest, Michigan to the north, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Various indigenous peoples inhabited what would become Indiana for thousands of years, some of whom the U.S. government expelled between 1800 and 1836. Indiana received its name because the state was largely possessed by native tribes even after it was granted statehood. Since then, settlement patterns in Indiana have reflected regional cultural segmentation present in the Eastern United States; the state's northernmost tier was settled primarily by people from New England and New York, Central Indiana by migrants fro ...

Mass Production
Mass production, also known as flow production or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before publication of the ''Britannica'' article. The concepts of mass production are applied to various kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to parts and assemblies of parts (household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, predate the Industrial Revolution by many centuries; however, ...

Harry Brearley
Harry Brearley (18 February 1871 – 14 July 1948) was an English metallurgist, credited with the invention of "rustless steel" (later to be called "stainless steel" in the anglophone world). Based in Sheffield, his invention brought affordable cutlery to the masses, and saw an expansion of the city's traditional cutlery trade. Life Brearley was born on 18 February 1871 in Sheffield, England, the son of John Brearley, a steelworker, and his wife, Jane Brearley née Senior.Oxford Dictionary of National Biography, accessed 2 April 2013 He left Woodside school at the age of twelve to enter his first employment as a labourer in the steelworks where his father worked, later getting the post of general assistant in the company's chemical laboratory. He married Helen Theresa Crank (1874–1955) on 23 October 1895. For several years, in addition to his laboratory work, he studied at home and later in formal evening classes, to specialize in steel production techniques and associated c ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martensitic
Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer to any crystal structure that is formed by diffusionless transformation. Properties Martensite is formed in carbon steels by the rapid cooling (quenching) of the austenite form of iron at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe3C). Austenite is gamma-phase iron (γ-Fe), a solid solution of iron and alloying elements. As a result of the quenching, the face-centered cubic austenite transforms to a highly strained body-centered tetragonal form called martensite that is supersaturated with carbon. The shear deformations that result produce a large number of dislocations, which is a primary strengthening mechanism of steels. The highest hardness of a pearlitic steel is 400 Brinell, whereas martensite can achieve 700 Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellite
Stellite is a range of cobalt-chromium alloys designed for wear resistance. The alloys may also contain tungsten or molybdenum and a small, but important, amount of carbon. History Stellite is a trademarked name of Kennametal Inc. Prior to that it was owned by Union Carbide, Stellite Division. Invented by Elwood Haynes in the early 1900s as a material for making cutlery that wouldn't stain or require constant cleaning. Composition Stellite alloys are a range of cobalt-based alloys, with significant proportions of chromium (up to 33%) and tungsten (up to 18%). Some of the alloys also contain nickel or molybdenum. Most of them are fairly high carbon content when compared to carbon steels, though they contain less than 3% iron, and in the stellite alloys the carbon is primarily associated with the chromium to form hard chromium carbide particles which are dispersed in the cobalt-based matrix. Properties Stellite is a family of completely non-magnetic and corrosion-resistant co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
