Cultivator No. 6
Cultivator No. 6 was the code name of a military trench-digging machine developed by the British Royal Navy at the beginning of World War II. The machine was originally known as White Rabbit Number Six; this code name was never officially recognised, but it was said to be derived from Churchill’s metaphorical ability to pull ideas out of a hat. The codename was changed to the less suggestive Cultivator Number Six to conceal its identity. The name was later changed to N.L.E. Tractors. Winston Churchill sometimes referred to the machine as his ''mole'' and the prototype machine was dubbed ''Nellie''. It was lightly armoured and carried no weapons. It was designed to advance upon an enemy position largely below ground level in a trench that it was itself excavating. On reaching the enemy's front line, it would serve as a ramp for the troops and possibly tanks following in its trench. Cultivator No. 6 was an enormous machine and was planned to be built in substantial numbers. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barrage (artillery)
In military usage, a barrage is massed sustained artillery fire (shelling) aimed at a series of points along a line. In addition to attacking any enemy in the kill zone, a barrage intends to suppress enemy movements and deny access across that line of barrage. The impact points along the line may be 20–30 yards/meters apart, with the total line length of the barrage zone anything from a few hundred to several thousand yards/meters long. Barrages can consist of multiple such lines, usually about 100 yards/meters apart, with the barrage shifting from one line to the next over time, or several lines may be targeted simultaneously. A barrage may involve a few or many artillery batteries, or even (rarely) a single gun. Typically each gun in a barrage, using indirect fire, will fire continuously at a steady rate at its assigned point for an assigned time before moving onto the next target, following the barrage's detailed timetable. Barrages typically use high-explosive shells, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucyrus, Ohio
Bucyrus ( ) is a city in the U.S. state of Ohio and the county seat of Crawford County, located in northern Ohio approximately 28 miles (45 km) west of Mansfield and southeast of Toledo. The population was 11,684 at the 2020 census. The city is the largest in Crawford County, and the center of the Bucyrus Micropolitan Statistical Area (as defined by the United States Census Bureau in 2003). History The origin of the name Bucyrus is not certain. It was given by Col. James Kilbourne, who laid out the town in 1821. One theory is that the name Bucyrus is derived from "beautiful" coupled with the name of Cyrus the Great, founder of the First Persian Empire. An alternate theory is that the city was named after Busiris, a city of ancient Egypt. The Bucyrus Foundry and Manufacturing Company, a predecessor to Bucyrus International, Inc. was founded in Bucyrus in 1880. The company moved to Wisconsin in 1893.

Engineering
Engineering is the use of scientific method, scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized List of engineering branches, fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of Accreditation Board for Engineering and Technology, ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct o ...

Plough
A plough or plow ( US; both ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses, but in modern farms are drawn by tractors. A plough may have a wooden, iron or steel frame, with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an ''aratrum''. Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant-feeder roots grow. Ploughs were initially powered by humans, but the use of farm ...

Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through hard rock, wet or dry soil, or sand. Tunnel diameters can range from (micro-TBMs) to to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs can be designed to excavate non-circular tunnels, including u-shaped, horseshoe, square or rectangular tunnels. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in urban areas. The major disadvan ...

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucket-wheel Excavator
A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They rank among the largest vehicles (land or sea) ever produced, and the largest of the bucket-wheel excavators (the 14,200 ton Bagger 293 still holds the Guinness World Record for the heaviest land-based vehicle ever constructed). History Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Pump Room
The Grand Pump Room is a historic building in the Abbey Churchyard, Bath, Somerset, England. It is adjacent to the Roman Baths and is named for water that is pumped into the room from the baths' hot springs. Visitors can drink the water or have other refreshments while there. It has been designated as a Grade I listed building since 1950. Along with the Lower Assembly Rooms, it formed a complex where social activity was centred, and where visitors to the city gathered. History The present building replaced an earlier one on the same site, designed by John Harvey at the request of Beau Nash, Bath's master of ceremonies, in 1706, before the discovery of Roman remains nearby. The main block, built of Bath stone, was begun by Thomas Baldwin, and the foundations of a Roman temple precinct were discovered during preparatory excavations. The North Colonnade of nine bays, with unfluted Ionic columns, was built by Baldwin in 1786–1790. Baldwin was dismissed, as a result of fina ...
