John Roebuck
John Roebuck of Kinneil FRS FRSE (1718 – 17 July 1794) was an English inventor and industrialist who played an important role in the Industrial Revolution and who is known for developing the industrial-scale manufacture of sulphuric acid. Life and work John Roebuck was born in Sheffield, where his father, also John Roebuck, had a prosperous manufacturing business. After attending Sheffield Grammar School and Dr. Philip Doddridge's academy at Northampton, Roebuck studied medicine at Edinburgh, where he developed a taste for chemistry from the lectures of William Cullen and Joseph Black. He finally graduated M.D. at the University of Leiden in 1742. Roebuck started medical practice at Birmingham, but devoted much of his time to chemistry, especially its practical applications. Among the most important of his early achievements in this field was the introduction, in 1746, of leaden condensing chambers for the manufacture of sulphuric acid. Together with Samuel Garbett, ...

Sheffield
Sheffield is a city in South Yorkshire, England, whose name derives from the River Sheaf which runs through it. The city serves as the administrative centre of the City of Sheffield. It is historically part of the West Riding of Yorkshire and some of its southern suburbs were transferred from Derbyshire to the city council. It is the largest settlement in South Yorkshire. The city is in the eastern foothills of the Pennines and the valleys of the River Don with its four tributaries: the Loxley, the Porter Brook, the Rivelin and the Sheaf. Sixty-one per cent of Sheffield's entire area is green space and a third of the city lies within the Peak District national park. There are more than 250 parks, woodlands and gardens in the city, which is estimated to contain around 4.5 million trees. The city is south of Leeds, east of Manchester, and north of Nottingham. Sheffield played a crucial role in the Industrial Revolution, with many significant inventions an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Leiden
Leiden University (abbreviated as ''LEI''; nl, Universiteit Leiden) is a public research university in Leiden, Netherlands. The university was founded as a Protestant university in 1575 by William, Prince of Orange, as a reward to the city of Leiden for its defence against Spanish attacks during the Eighty Years' War. As the oldest institution of higher education in the Netherlands, it enjoys a reputation across Europe and the world. Known for its historic foundations and emphasis on the social sciences, the university came into particular prominence during the Dutch Golden Age, when scholars from around Europe were attracted to the Dutch Republic due to its climate of intellectual tolerance and Leiden's international reputation. During this time, Leiden became the home to individuals such as René Descartes, Rembrandt, Christiaan Huygens, Hugo Grotius, Baruch Spinoza and Baron d'Holbach. The university has seven academic faculties and over fifty subject departments while housin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Watt
James Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water. Watt attempted to commercialise his invention, but experienced great financial ...

Newcomen Engine
The atmospheric engine was invented by Thomas Newcomen in 1712, and is often referred to as the Newcomen fire engine (see below) or simply as a Newcomen engine. The engine was operated by condensing steam drawn into the cylinder, thereby creating a partial vacuum which allowed the atmospheric pressure to push the piston into the cylinder. It was historically significant as the first practical device to harness steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines. Hundreds were constructed throughout the 18th century. James Watt's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency. Many atmospheric engines were converted to the Watt design, for a price which was based on a fraction of the fuel-savings. As a result, Watt is today better known than Newcomen in relation to the origin of the steam engine. Precursors Prior to Newcomen a number of smal ...

Bo'ness, Scotland
Borrowstounness (commonly known as Bo'ness ( )) is a town and former burgh and seaport on the south bank of the Firth of Forth in the Central Lowlands of Scotland. Historically part of the county of West Lothian, it is a place within the Falkirk council area, northwest of Edinburgh and east of Falkirk. At the 2011 United Kingdom census, the population of the Bo'ness locality was 15,100. Until the 20th century, Bo'ness was the site of various industrial activities, including coal mining, saltmaking and pottery production. With its location beside the Forth, the town and its harbour grew in importance in the industrial revolution and later continued to grow into the Victorian era. Since the late 20th century, deindustrialisation has changed the nature of the town, with the coal mine closing in 1982 and the waterfront area now being primarily used for leisure purposes. However, some industry remains in the town including an ironworks and a timberyard/sawmill beside the Forth. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colliery
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a ' pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to ...

Royal Artillery
The Royal Regiment of Artillery, commonly referred to as the Royal Artillery (RA) and colloquially known as "The Gunners", is one of two regiments that make up the artillery arm of the British Army. The Royal Regiment of Artillery comprises thirteen Regular Army regiments, the King's Troop Royal Horse Artillery and five Army Reserve regiments. History Formation to 1799 Artillery was used by the English army as early as the Battle of Crécy in 1346, while Henry VIII established it as a semi-permanent function in the 16th century. Until the early 18th century, the majority of British regiments were raised for specific campaigns and disbanded on completion. An exception were gunners based at the Tower of London, Portsmouth and other forts around Britain, who were controlled by the Ordnance Office and stored and maintained equipment and provided personnel for field artillery 'traynes' that were organised as needed. These personnel, responsible in peacetime for maintaining the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stirlingshire

Carron Company
The Carron Company was an ironworks established in 1759 on the banks of the River Carron near Falkirk, in Stirlingshire, Scotland. After initial problems, the company was at the forefront of the Industrial Revolution in the United Kingdom. The company prospered through its development and production of a new short-range and short-barrelled naval cannon, the carronade. The company was one of the largest iron works in Europe through the 19th century. After 223 years, the company became insolvent in 1982 and was later acquired by the Franke Corporation, being rebranded Carron Phoenix. Early years The original founders of the Carron Works were: John Roebuck, a medical doctor and chemist from Sheffield; his two brothers, Thomas Roebuck and Ebenezer Roebuck; Samuel Garbett, a merchant from Birmingham; William Cadell, Senior, an industrialist from a merchant family, from Cockenzie, East Lothian; his son, William Cadell, Junior; and John Cadell.

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder ...

Acid
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Inf ...
