Jonathan Hornblower
Jonathan Hornblower (5 July 1753 – 23 February 1815) was an English pioneer of steam power. Personal life The son of Jonathan Hornblower the Elder and the brother of Jabez Carter Hornblower, two fellow pioneers, the young Hornblower was educated at Truro Grammar School. He was baptised at Trelever on 25 July 1773, aged 20 (he and his family were much involved in Baptist churches in Cornwall), and was apprenticed to a metal-working tradesman at Penryn. He married twice, first to his cousin Rosamund Phillips in 1775 and later to Elizabeth Jordan with whom he had two surviving daughters, Rosamund (1789) and Elizabeth (1790). He died on 23 February 1815 and is buried in St Gluvias Churchyard. Compound engine He invented the compound steam engine in 1781 and patented it on 16 July in the same year. This type of engine has two cylinders, an evolution from the single low pressure, condensing engines of Newcomen and later Watt (who introduced the separate condenser), it intr ...

Truro Cathedral School
Truro Cathedral School was a Church of England school for boys in Truro, Cornwall. An ancient school refounded in 1549 as the Truro Grammar School, after the establishment of Truro Cathedral in the last quarter of the 19th century it was responsible for educating the cathedral's choristers and became known as the Cathedral School. The school closed in July 1982 and the education of choristers was transferred to Polwhele House Preparatory School. History An ancient foundation, the school existed before the Reformation as the chantry school of St Mary's Church, Truro. In 1549, following Edward VI's Dissolution of Colleges Act 1547 which suppressed all chantries, the school was refounded and took on a new identity as Truro Grammar School. However, as reported by Nicholas Carlisle in his survey of 1818, "The Grammar School at Truro owes its origin and endowment to some benevolent person, whose name is now not known."

Boulton & Watt
Boulton & Watt was an early British engineering and manufacturing firm in the business of designing and making marine and stationary steam engines. Founded in the English West Midlands around Birmingham in 1775 as a partnership between the English manufacturer Matthew Boulton and the Scottish engineer James Watt, the firm had a major role in the Industrial Revolution and grew to be a major producer of steam engines in the 19th century. The engine partnership The partnership was formed in 1775 to exploit Watt's patent for a steam engine with a separate condenser. This made much more efficient use of its fuel than the older Newcomen engine. Initially the business was based at the Soho Manufactory near Boulton's Soho House on the southern edge of the then-rural parish of Handsworth. However most of the components for their engines were made by others, for example the cylinders by John Wilkinson. In 1795, they began to make steam engines themselves at their Soho Foundry in ...

People From Chacewater
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineers From Cornwall
Engineers, as practitioners of engineering, are professionals who invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering dis ...

1753 Births
Events January–March * January 3 – King Binnya Dala of the Hanthawaddy Kingdom orders the burning of Ava, the former capital of the Kingdom of Burma. * January 29 – After a month's absence, Elizabeth Canning returns to her mother's home in London and claims that she was abducted; the following criminal trial causes an uproar. * February 17 – The concept of electrical telegraphy is first published in the form of a letter to ''Scots' Magazine'' from a writer who identifies himself only as "C.M.". Titled "An Expeditious Method of Conveying Intelligence", C.M. suggests that static electricity (generated by 1753 from "frictional machines") could send electric signals across wires to a receiver. Rather than the dot and dash system later used by Samuel F.B. Morse, C.M. proposes that "a set of wires equal in number to the letters of the alphabet, be extended horizontally between two given places" and that on the receiving side, "Let a ball be suspen ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional radi ...

William McNaught (Glasgow)
William McNaught (1813–1881) was a Scottish engineer, from Glasgow, who patented a compound steam engine in 1845. This was a technique of improving the efficiency of a standard simple Boulton & Watt beam engine. The engine was compounded by adding a high-pressure cylinder between the support column and the flywheel, on the side opposite the low-pressure cylinder. This improvement could be retrospectively fitted to existing engines. Family William McNaught was born on 27 May 1813 at Paisley, Renfrewshire, Scotland, son of John McNaught, the inventor of the McNaught indicator. Engine building McNaught patented his compound steam engine in 1845 (Patent no. 11001). He relocated to Manchester in 1849. The Robertson Street workshop was operated by William McNaught & Son as "Makers of Steam-Engine Indicators, Steam Gauges, etc" at 12 Hampden Terrace, Glasgow, at least until 1895. MacNaught died in Chorlton upon Medlock, Manchester Manchester () i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Efficiency
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines- #Internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and #External combustion engines ( steam piston, steam turbine, and the Stirling cycle engine). Each of these engines has thermal efficiency characteristics that are unique to it. Engine efficiency, transmission design, and tire design all contribute to a vehicle's fuel efficiency. Mathematical definition The efficiency of an engine is defined as ratio of the useful work done to the heat provided. : \eta = \frac = \frac where, Q_1 is the heat absorbed and Q_1-Q_2 is the work done. Please note that the term work done relates to the power delivered at the clutch or at the driveshaft. This means the friction and other losses are subtracted from the work done by thermodynamic expansion. Thus a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Woolf
Arthur Woolf (1766, Camborne, Cornwall – 16 October 1837, Guernsey) was a Cornish engineer, most famous for inventing a high-pressure compound steam engine. In this way he made an outstanding contribution to the development and perfection of the Cornish engine. Woolf left Cornwall in 1785 to work for Joseph Bramah's engineering works in London. He worked there and at other firms as an engineer and engine builder until 1811 experimenting with high pressure steam and a much improved boiler. He then returned to Cornwall. Michael Loam, who introduced the man engine to the UK, was trained by him. When he returned to Cornwall, beam engine designs were crude, shackled by outdated Watt patents and poor engineering, struggling to compete with large water wheels, even used underground. He learned from Bramah that to move forward meant adopting much improved engineering techniques, for it was Bramah who invented quality control. Woolf was chief engineer to Harvey & Co of Hayle, ...
