USFS Osprey
USFS ''Osprey'' was an American steamer that served as a fishery patrol vessel in the waters of the Territory of Alaska. She was in commission in the United States Bureau of Fisheries (BOF) from 1913 to 1921, and was the first vessel the BOF ever operated on fishery patrols in Alaska. Before the BOF purchased her, she was the commercial cannery tender ''Wigwam'' from 1895 to 1912. After her BOF career ended, she operated as a commercial motor tug with the name ''Foss No. 19'' from 1922 to 1965 and with the name ''Kiowa'' from 1965 until she sank in 1978. Early history The vessel was constructed as the coal-burning commercial steamer ''Wigwam'' in San Francisco, California, in 1895. Under the ownership of the Alaska Packers Association, she became one of the first cannery tenders to operate in Alaska. At some point prior to her U.S. Bureau of Fisheries (BOF) service, the Alaska Packers Association rebuilt her to a high standard based on recommendations made by the Steambo ...

Wigwam
A wigwam, wickiup, wetu (Wampanoag), or wiigiwaam (Ojibwe, in syllabics: ) is a semi-permanent domed dwelling formerly used by certain Native American tribes and First Nations people and still used for ceremonial events. The term ''wickiup'' is generally used to refer to these kinds of dwellings in the Southwestern United States and Western United States and Northwest Alberta, Canada, while ''wigwam'' is usually applied to these structures in the Northeastern United States as well as Ontario and Quebec in central Canada Central Canada (french: Centre du Canada, sometimes the Central provinces) is a region consisting of Canada's two largest and most populous provinces: Ontario and Quebec. Geographically, they are not at the centre of Canada but instead overlap w .... The names can refer to many distinct types of Indigenous structures regardless of location or cultural group. The wigwam is not to be confused with the Native Plains tipi, which has a different construction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Territory Of Alaska
The Territory of Alaska or Alaska Territory was an organized incorporated territory of the United States from August 24, 1912, until Alaska was granted statehood on January 3, 1959. The territory was previously Russian America, 1784–1867; the Department of Alaska, 1867–1884; and the District of Alaska, 1884–1912. Origin Passage of the 1899 Criminal Code which, among other things, included a tax on liquor, led to increased calls for Alaskan representation in Congress, and the debate finally ended on August 24, 1912, when the Alaska District became an organized, incorporated territory of the United States. The ''Second Organic Act'' of 1912 renamed the District the Territory of Alaska. By 1916, its population was about 58,000. James Wickersham, a Delegate to Congress, introduced Alaska's first statehood bill, but it failed for lack of interest from Alaskans. Even President Warren G. Harding's unprecedented visit in 1923 (just days before his death) could not create wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in hu ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairbanks-Morse
Fairbanks, Morse and Company was an American manufacturing company in the late 19th and early 20th century. Originally a weighing scale manufacturer, it later diversified into pumps, engines, windmills, coffee grinders, radios, farm tractors, feed mills, locomotives, and industrial supplies until it was purchased by Penn Texas in 1958. There are three separate corporate entities that could be considered successors to the company, none of which is a complete and direct descendant of the original company. All claim the heritage of Fairbanks Morse and Company: * Fairbanks Scales is a privately owned company in Kansas City, Missouri, that manufactures scales * Fairbanks Morse Defense, a subsidiary company of Arcline Investment Management, is a company based in Beloit, Wisconsin, that manufactures and services engines * Fairbanks Nijhuis is a part of Pentair Water in Kansas City, Kansas, and manufactures pumps Founding and early history Fairbanks Morse and Company began in 1823 whe ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corliss Steam Engine
A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the American engineer George Henry Corliss of Providence, Rhode Island. Engines fitted with Corliss valve gear offered the best thermal efficiency of any type of stationary steam engine until the refinement of the uniflow steam engine and steam turbine in the 20th century. Corliss engines were generally about 30 percent more fuel efficient than conventional steam engines with fixed cutoff. This increased efficiency made steam power more economical than water power, allowing industrial development away from millponds. Corliss engines were typically used as stationary engines to provide mechanical power to line shafting in factories and mills and to drive dynamos to generate electricity. Many were quite large, standing many metres tall and developing several hundred horsepower, albeit at low speed, turning massive fly ...

Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.
