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 introd ...

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 Abolition of Chantries Act of 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."Nicholas Carlisle, ''A Concise Description of the Endowed Gramma ...

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 di ...

People From Chacewater
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Engineers From Cornwall
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials 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 ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

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 suspende ...

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 ra ...

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, on 8 January 1881, leavi ... [...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 an ... [...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. As such 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. Whereupon he returned to Cornwall. Michael Loam, inventor of the man engine, was trained by him. When he returned to Cornwall, beam engine designs were crude, shackled by outdated James Watt, 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, the le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
