High Quality Content by WIKIPEDIA articles! A weigh house or weighing house is a building at or within which goods, and the like, are weighed. Most of these buildings were built before 1800, prior to the establishment of international standards for weights. As public control of the weight of goods was very important, they were run by local authorities who would also use them for the levying of taxes on goods transported through or sold within the city. Therefore, weigh houses would often be near a market square or town centre. Between 1550 and about 1690 people accused of witchcraft were at times brought to a weigh house in order to be subjected to a "witch test". If a person was found to be lighter than a set weight, he or she was...

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces. Gas metal arc welding Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an...

A well intervention, or 'well work', is any operation carried out on a oil or gas well during, or at the end of its productive life, that alters the state of the well and or well geometry, provides well diagnostics or manages the production of the well.Subsea well interventions offer up many challenges and requires much advanced planning. The cost of subsea intervention has in the past inhibited the intervention but in the current climate are much more viable. These interventions are commonly executed from Light/medium intervention vessels or Mobile Offshore Drilling Units (MODU) for the heavier interventions such as Snubbing and Workover drilling...

Naturally fractured reservoirs are anisotropic systems whose flow characteristics depend on the fractures network. Their permeability variation is not only stratigraphic in nature, but is also caused by the fractures’ distribution, orientation and permeability impairment within the fractures caused by pressure solution or mineralization. The reservoir becomes more complex when both the matrix and fracture exhibit anisotropy and have the capability to flow into the wellbore as in the double permeability case. Well test analysis in these reservoirs has been based on the radial flow model, even when it is widely believed that such reservoirs are anisotropic. The radial flow model is however only applicable to purely homogeneous system. It...

High Quality Content by WIKIPEDIA articles! Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, natural gas, or petroleum. Drilling for the exploration of the nature of the material underground (for instance in search of metallic ore) is best described as borehole drilling, or 'drilling'. The earliest wells were water wells, shallow pits dug by hand in regions where the water table approached the surface, possibly with masonry walls lining the interior to prevent collapse. Modern drilling techniques utilize long drill shafts, producing holes much narrower and deeper than could be produced by digging. Данное издание не является...

This article summarizes Welsh 0-6-2T locomotives and, where possible, give links to main articles.The 0-6-2 tank locomotive could well be described as the standard steam locomotive of the railways of South Wales. Many of the independent railways used them and, at the grouping of 1923, the survivors passed into Great Western Railway (GWR) stock. The GWR perpetuated the type in the GWR 5600 Class. In addition, the other major railway company in Wales, the LNWR also had the LNWR Webb Coal Tank Class, though this was grouped into the LMS not the GWR.The railways of South Wales seem to have had a particular liking for the 0-6-2T type. This was because the nature of the work they undertook demanded...

High Quality Content by WIKIPEDIA articles! The Westland Whirlwind was a British twin-engined heavy fighter developed by Westland Aircraft. It was the Royal Air Force`s first single-seat, twin-engined, cannon-armed fighter, and a contemporary of the Supermarine Spitfire and Hawker Hurricane. It was one of the fastest aircraft in service when it flew in the late 1930s, and was much more heavily armed than any other. However, protracted development problems with its Rolls-Royce Peregrine engines delayed the entire project and only a relatively small number were ever built. During the Second World War only two RAF squadrons were equipped with the Whirlwind, and despite successful use as a fighter-bomber it was withdrawn from service in 1943.

A wheel is a circular device that is capable of rotating on its axis, facilitating movement or transportation whilst supporting a load, or performing labour in machines. Common examples are found in transport applications. A wheel, together with an axle overcomes friction by facilitating motion by rolling. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by application of another external force. More generally the term is also used for other circular objects that rotate or turn, such as a ship's wheel, steering wheel and flywheel. Данное издание не является оригинальным. Книга...

High Quality Content by WIKIPEDIA articles! Metal whiskers differ from metallic dendrites in several respects; dendrites are fern-shaped, and grow across the surface of the metal, while metal whiskers are hair-like and project at a right angle to the surface. Dendrite growth requires moisture capable of dissolving the metal into a solution of metal ions which are then redistributed by electromigration in the presence of an electromagnetic field. While the precise mechanism for whisker formation remains unknown, it is known that whisker formation does not require either dissolution of the metal or the presence of an electromagnetic field. Whiskers can cause short circuits and arcing in electrical equipment. The phenomenon was discovered...
