William Peter Durtnall
William Peter Durtnall (1873–1947), M.I.Mar.E., M.I.Auto.E., M.I.Loco.E, was a British electrical engineer and inventor, and a captain in the Royal Air Force. He was involved in both marine and locomotive engineering and invented a thermoelectric engine patented as the "Paragon". He transferred from the Royal Navy Volunteer Reserve to a temporary commission as a captain in the Royal Air Force in April 1918. Early life Durtnall was born in Herne Bay, Kent 1873 and baptised there on 2 February 1873. His father was a mariner before marriage, and later became a railway carman. His mother ran a lodging house, and his grandfather had been a sailmaker at Chatham Dockyard. Career Durtnall was apprenticed to Willans at Rugby, where he was involved in a junior position in work relating to the Heilmann steam locomotives. He first served at the Herne Bay Electric Light Co. in 1886. He then served at the Maxim Weston Electric Company's works at Dalston under Mr W J L Hamilton, Engineer ...

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Battery Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Petrol Engine
A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as ''E10'' and ''E85''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol e ...

Cristiani Compressed Steam System
A steam diesel hybrid locomotive is a railway locomotive with a piston engine which could run on either steam from a boiler or diesel fuel. Examples were built in the United Kingdom, Soviet Union and Italy but the relatively high cost of fuel oil, or failure to resolve problems caused by technical complexity, meant that the designs were not pursued. Kitson-Still system In 1926 Kitson and Company, Leeds, built an experimental example for the London and North Eastern Railway, using as their model the Still engine already in use for stationary and marine applications. It was on trial until 1934, but then scrapped. It was designed because a steam engine offered a high starting torque—a tractive force of was available—while a diesel engine offered a high fuel efficiency and it was considered desirable to combine the two. Construction In outline the machine resembled a conventional 2-6-2T steam locomotive, but it had four pairs of horizontally opposed cylinders (13½ inch bo ...

Hawthorn Leslie And Company
R. & W. Hawthorn, Leslie and Company, Limited, usually referred to as Hawthorn Leslie, was a shipbuilder and locomotive manufacturer. The company was founded on Tyneside in 1886 and ceased building ships in 1982. History The company was formed by the merger of the shipbuilder A. Leslie and Company in Hebburn with the locomotive works of R and W Hawthorn at St. Peter's in Newcastle upon Tyne in 1886. The company displaced its locomotive manufacturing interests in 1937 to Robert Stephenson and Company, which became ''Robert Stephenson and Hawthorns Ltd.'' Perhaps the most famous ship built by the Company was HMS ''Kelly'', launched in 1938 and commanded by Lord Louis Mountbatten. In 1954, the shipbuilding and marine engine activities were put into separate subsidiaries, Hawthorn Leslie (Shipbuilders) Ltd. and Hawthorn Leslie (Engineers) Ltd. In 1968 the Company's shipbuilding interests were merged with that of Swan Hunter and the Vickers Naval Yard to create Swan Hunter & Tyne ...

Royal Naval Reserve
The Royal Naval Reserve (RNR) is one of the two volunteer reserve forces of the Royal Navy in the United Kingdom. Together with the Royal Marines Reserve, they form the Maritime Reserve. The present RNR was formed by merging the original Royal Naval Reserve, created in 1859, and the Royal Naval Volunteer Reserve (RNVR), created in 1903. The Royal Naval Reserve has seen action in World War I, World War II, the Iraq War, and War in Afghanistan. History Establishment The Royal Naval Reserve (RNR) has its origins in the Register of Seamen, established in 1835 to identify men for naval service in the event of war, although just 400 volunteered for duty in the Crimean War in 1854 out of 250,000 on the Register. This led to a Royal Commission on Manning the Navy in 1858, which in turn led to the Naval Reserve Act of 1859. This established the RNR as a reserve of professional seamen from the British Merchant Navy and fishing fleets, who could be called upon during times of war ...

Raphael Tuck & Sons
Raphael Tuck & Sons was a business started by Raphael Tuck and his wife in Bishopsgate in the City of London in October 1866,Picture Postcards and Their Publishers, by Anthony Byatt, page 288 selling pictures and greeting cards, and eventually selling postcards, which was their most successful line. Their business was one of the best known in the "postcard boom" of the late 1890s and early 1900s. During the Blitz, the company headquarters, Raphael House, was destroyed, including the originals for most of their series. The company never fully recovered. History Raphael was married to the former Ernestine Lissner in March 1848. She gave birth to seven children, four boys and three girls, all born in Prussia prior to their migration to England. As the family of seven children grew older, the children provided more help to the business. Raphael sent out his sons, Herman, Adolph and Gustave, to bring in more business. Herman and Adolph also went on selling trips, and at the end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
