Blau Gas
Blau gas () is an artificial illuminating gas that is similar to propane. It was named after its inventor, Hermann Blau of Augsburg, Germany. Rarely used or produced today, it was manufactured by decomposing mineral oils in retorts by heat, and compressing the resulting naphtha until it liquefied. It was transported in liquid condition, and, like LPG, when released returns to a gaseous state. The density relative to air is 0.963, giving an average molecular weight of 27.9. One litre at 0 °C and contains 1.246 grams, of which 1.042 is carbon and 0.204 is hydrogen, giving an average of 1.94 carbon atoms and 4.54 hydrogen atoms per molecule. Blau gas contains about 50% olefins In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. The double bond may be internal or at the terminal position. Terminal alkenes are also known as α-olefins. The International Union of P ... (alkenes), 37% methane and other alkanes, 6% hy ...

Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the Fischer–Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fu ...

Lighting
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (architecture), Daylighting (using windows, skylights, or Architectural light shelf, light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscaping, landscape projects. History With the Control of fire by early humans, discovery of fire, the earliest form of artificial lighting used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Gas
Fuel gas is one of a number of fuels that under ordinary conditions are gaseous. Most fuel gases are composed of hydrocarbons (such as methane and propane), hydrogen, carbon monoxide, or mixtures thereof. Such gases are sources of energy that can be readily transmitted and distributed through pipes. Fuel gas is contrasted with liquid fuels and solid fuels, although some fuel gases are Liquefaction of gases, liquefied for storage or transport (for example, autogas and Liquefied petroleum gas, liquified petroleum gas). While their gaseous nature has advantages, avoiding the difficulty of transporting solid fuel and the dangers of spillage inherent in liquid fuels, it also has limitations. It is possible for a fuel gas to be undetected and cause a gas explosion. For this reason, odorizers are added to most fuel gases. The most common type of fuel gas in current use is natural gas. Types of fuel gas There are two broad classes of fuel gases, based not on their chemical composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K-1 (airship)
The K-1 was an experimental blimp designed by the United States Navy in 1929. The K-1 was not the prototype of the later K-class blimps. Procurement Due to the inability to get Congressional approval for the construction of an airship, the navy used the ploy of ordering a "universal" control car (type J/K) which could be used on the J-class blimps from the Naval Aircraft Factory. An order was placed with Goodyear Tire and Rubber Company for an envelope to hold "experimental gases". To complete the deception, there is no record of the US Navy assigning a serial number A serial number (SN) is a unique identifier used to ''uniquely'' identify an item, and is usually assigned incrementally or sequentially. Despite being called serial "numbers", they do not need to be strictly numerical and may contain letters ... to the K-1, and standard Army TC-class blimp tail fins were procured from Goodyear.

History Of Manufactured Gas
The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century. These "synthetic fuel gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") were made by gasification of combustible materials, usually coal, but also wood and oil, by heating them in enclosed ovens with an oxygen-poor atmosphere. The fuel gases generated were mixtures of many chemical substances, including hydrogen, methane, carbon monoxide and ethylene. Coal gas also contains significant quantities of unwanted sulfur and ammonia compounds, as well as heavy hydrocarbons, and must be purified before use. The first attempts to manufacture fuel gas in a commercial way were made in the period 1795–1805 in France by Philippe LeBon, and in England by William Murdoch. Although precursors can be found, it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Riedinger
August Riedinger (9 October 1845 – 15 January 1919) Augsburg city archive was a German businessman who operated gas companies in Germany and Europe and also participated in balloon and airship manufacturing. Life Riedinger was born in 1845 as the son of the industrialist Ludwig August Riedinger in Augsburg. After six years of studies at the Zurich Polytechnic he entered his father's machinery and bronzeworks business in 1877.

Airship
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells.

LZ 127 Graf Zeppelin
LZ 127 ''Graf Zeppelin'' () was a German passenger-carrying hydrogen-filled rigid airship that flew from 1928 to 1937. It offered the first commercial transatlantic flight, transatlantic passenger flight service. The ship was named after the German airship pioneer Ferdinand von Zeppelin, a count () in the German nobility. It was conceived and operated by Hugo Eckener, the chairman of Luftschiffbau Zeppelin. ''Graf Zeppelin'' made 590 flights totalling almost 1.7 million kilometres (over 1 million miles). It was operated by a crew of 36 and could carry 24 passengers. It was the longest and largest airship in the world when it was built. It made the first circumnavigation of the world by airship, and the first nonstop crossing of the Pacific Ocean by air; its range was enhanced by its use of Blau gas as a fuel. It was built using funds raised by public subscription and from the German government, and its operating costs were offset by the sale of special postage stamps to sta ...

Buoyancy Compensator (aviation)
The static buoyancy of airships in flight is not constant. It is therefore necessary to control the altitude of an airship by controlling its buoyancy: buoyancy compensation. Changes which have an effect on buoyancy * Changes in air temperature (and thus the density of air) * Changes in lifting gas temperature (for example, the heating of the hull by the sun). * Accumulation of additional ballast (for example, precipitation or icing on the envelope) * Changes in ballast (for example, during a flight maneuver or the dropping of ballast) * Changes in weight of fuel on board, due to fuel consumption. This was a challenge especially in the large historic airships like the Zeppelins. For example, on a flight from Friedrichshafen to Lakehurst, the rigid airship USS Los Angeles (ZR-3), LZ 126, built in 1923-24, used 23,000 kg gasoline and 1300 kg of oil (an average consumption of 290 kg/100 km). During the landing the airship had to release approximately 24,000 cubi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Car
A railroad car, railcar (American English, American and Canadian English), railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and International Union of Railways, UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport network (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some Passenger railroad car, passenger cars are self-propelled in which case they may be either single railcars or make up multiple units. The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner, though the term has Bogie, other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to ...
