Bulk material handlingBulk material handling is an engineering field that is centered on the design of equipment used for the handling of dry materials. Bulk materials are those dry materials which are powdery, granular or lumpy in nature, and are stored in heaps. Examples of bulk materials are minerals, ores, coal, cereals, woodchips, sand, gravel, clay, cement, ash, salt, chemicals, grain, sugar, flour and stone in loose bulk form. It can also relate to the handling of mixed wastes.
Brownfield landBrownfield refers to land that is abandoned or underutilized due to pollution from industrial use. The specific definition of brownfield land varies and is decided by policy makers and/or land developers within different countries. The main difference in definitions of whether a piece of land is considered a brownfield or not depends on the presence or absence of pollution. Overall, brownfield land is a site previously developed for industrial or commercial purposes and thus requires further development before reuse.
BobbinA bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. Bobbins are typically found in industrial textile machinery, as well as in sewing machines, fishing reels, tape measures, film rolls, cassette tapes, within electronic and electrical equipment, and for various other applications. Bobbins are used in spinning, weaving, knitting, sewing, and lacemaking.
SeraingSeraing (səʁɛ̃; Serè) is a city and municipality of Wallonia located in the province of Liège, Belgium. The municipality consists of the following districts: Boncelles, Jemeppe-sur-Meuse, Ougrée, and Seraing. With Liège, Herstal, Saint-Nicolas, Ans, and Flémalle, it forms the greater Liège agglomeration (600,000 inhabitants). To the south of Seraing are the Condroz and the Ardennes regions. In addition to its steel factories, Seraing is home to the crystal manufacture Val Saint Lambert, which has been operating on the site of an old Cistercian abbey since 1826.
Piece workPiece work or piecework is any type of employment in which a worker is paid a fixed piece rate for each unit produced or action performed, regardless of time. When paying a worker, employers can use various methods and combinations of methods.
AditAn adit (from Latin aditus, entrance) or stulm is a horizontal or nearly horizontal passage to an underground mine. Miners can use adits for access, drainage, ventilation, and extracting minerals at the lowest convenient level. Adits are also used to explore for mineral veins. Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain.
Single- and double-acting cylindersIn mechanical engineering, the cylinders of reciprocating engines are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston. A single-acting cylinder in a reciprocating engine is a cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of reciprocating engine.
High StreetHigh Street is a common street name for the primary business street of a city, town, or village, especially in the United Kingdom and Commonwealth. It implies that it is the focal point for business, especially shopping. It is also a metonym for the retail sector. With the rapid increase in consumer expenditure the number of High Streets in England grew from the 17th century and reached a peak in Victorian Britain where, drawn to growing towns and cities spurred on by the Industrial Revolution, the rate of urbanisation was unprecedented.
Cotton-spinning machineryCotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton industry. Cotton spinning machinery was installed in large factories, commonly known as cotton mills. Spinning wheel The spinning wheel was invented in the Islamic world by 1030.
Friendly societyA friendly society (sometimes called a benefit society, mutual aid society, benevolent society, fraternal organization or ROSCA) is a mutual association for the purposes of insurance, pensions, savings or cooperative banking. It is a mutual organization or benefit society composed of a body of people who join together for a common financial or social purpose. Before modern insurance and the welfare state, friendly societies provided financial and social services to individuals, often according to their religious, political, or trade affiliations.
