Still Engine
The Still engine was a piston engine that simultaneously used both steam power from an external boiler, and internal combustion from gasoline or diesel, in the same unit. The waste heat from the cylinder and internal combustion exhaust was directed to the steam boiler, resulting in claimed fuel savings of up to 10%. History The inventor, William Joseph Still, patented his device in 1917 and on 26 May 1919 in London he and his collaborator Captain Francis Acland (1857–1943, a consulting engineer formerly of the Royal Artillery) announced it at a meeting, chaired by steam turbine inventor Charles Algernon Parsons, at the Royal Society of Arts. Acland described a continuous process by which a double-acting cylinder is powered on one side by internal combustion and on the other by steam from a boiler heated principally by the waste heat from the water jacket and exhaust gases. He explained how the reserve of energy represented by the steam pressure in the boiler provided for any occ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intr ...

Double-acting Cylinder
In 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. Single-acting 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. They are almost universal in internal combustion engines (e.g. petrol and diesel engines) and are also used in many external combustion engines such as Stirling engine A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the ''working fluid'') between different temperatures, resulting in a net conversion of heat energy to mechanical work.

Steam Engines
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receivership
In law, receivership is a situation in which an institution or enterprise is held by a receiver—a person "placed in the custodial responsibility for the property of others, including tangible and intangible assets and rights"—especially in cases where a company cannot meet its financial obligations and is said to be insolvent.Philip, Ken, and Kerin Kaminski''Secured Lender'', January/February 2007, Vol. 63 Issue 1, pages 30-34,36. The receivership remedy is an equitable remedy that emerged in the English chancery courts, where receivers were appointed to protect real property. Receiverships are also a remedy of last resort in litigation involving the conduct of executive agencies that fail to comply with constitutional or statutory obligations to populations that rely on those agencies for their basic human rights. Receiverships can be broadly divided into two types: *Those related to insolvency or enforcement of a security interest. *Those where either **One is Incapable of ...

London And North Eastern Railway
The London and North Eastern Railway (LNER) was the second largest (after LMS) of the " Big Four" railway companies created by the Railways Act 1921 in Britain. It operated from 1 January 1923 until nationalisation on 1 January 1948. At that time, it was divided into the new British Railways' Eastern Region, North Eastern Region, and partially the Scottish Region. History The company was the second largest created by the Railways Act 1921. The principal constituents of the LNER were: * Great Eastern Railway * Great Central Railway * Great Northern Railway * Great North of Scotland Railway * Hull and Barnsley Railway * North British Railway * North Eastern Railway The total route mileage was . The North Eastern Railway had the largest route mileage of , whilst the Hull and Barnsley Railway was . It covered the area north and east of London. It included the East Coast Main Line from London to Edinburgh via York and Newcastle upon Tyne and the routes from Edinburgh to ...

Steam Diesel Hybrid Locomotive
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 bore × 1 ...

Kitson And Company
Kitson and Company was a locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England. Early history The company was started in 1835 by James Kitson (businessman), James Kitson at the Airedale Foundry, off Pearson Street, Hunslet, with Charles Todd as a partner. Todd had been apprenticed to Matthew Murray at the Round Foundry in Holbeck, Leeds. Initially, the firm made parts for other builders, until it was joined in 1838 by David Laird, a wealthy farmer who was looking for investments, and the company became Todd, Kitson and Laird. That year saw the production of the company's first complete locomotives, either for the North Midland Railway, North Midland or the Liverpool and Manchester Railway. However, Todd left almost immediately to form Railway Foundry, Shepherd and Todd, and the company was known variously as Kitson and Laird or Laird and Kitson. The order for six engines by the Liverpool and Manchester began with ''LMR 57 Lion, Lion'', which still exists. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Funnel Line
Alfred Holt and Company, trading as Blue Funnel Line, was a UK shipping company that was founded in 1866 and operated merchant ships for 122 years. It was one of the UK's larger shipowning and operating companies, and as such had a significant role in the country's overseas trade and in the First World War, First and World War II, Second World Wars. Its seafarers later went to fill various roles in the British maritime shore based establishment, including Malcolm Machlachlan, a lecturer in Glasgow and a popular author of books on Maritime business. History Foundation and expansion Alfred Holt founded the business on 16 January 1866. The main operating subsidiary was the Ocean Group plc, Ocean Steam Ship Company, which owned and operated the majority of the company's vessels. A Netherlands, Dutch subsidiary, the Nederlandsche Stoomvaart Maatschappij Oceaan, was founded in 1891, as was the East India Ocean Steam Ship Company, operated from Singapore. This latter was sold in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Prefix
A ship prefix is a combination of letters, usually abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, such as identifying the vessel's mode of propulsion, purpose, or ownership/nationality. In the modern environment, prefixes are cited inconsistently in civilian service, whereas in government service a vessel's prefix is seldom omitted due to government regulations dictating that a certain prefix be used. Today the common practice is to use a single prefix for all warships of a nation's navy, and other prefixes for auxiliaries and ships of allied services, such as coast guards. For example, the modern navy of Japan adopts the prefix "JS" – Japanese Ship. However, not all navies use prefixes. Among the Blue-water navy, blue-water navies, those of France, Brazil, China, Russia, Germany, and Spain do not use ship prefixes. NATO designations such as FS (French Ship), FGS (Federal German Ship), and SPS (Spanish Ship) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotts Shipbuilding And Engineering Company
Scotts Shipbuilding and Engineering Company Limited, often referred to simply as Scotts, was a Scottish shipbuilding company based in Greenock on the River Clyde. In its time in Greenock, Scotts built over 1,250 ships. History John Scott founded the company in 1711. He built herring busses and small craft. He was succeeded by his son William Scott (1722-1769) and another son. In 1765 they built their first square-rigged vessel. William's son John (1752-1837) expanded the shipyard to a major shipbuilding company. The Scott family took over the Greenock Foundry in 1790. In 1791, Scott & Co. built , of 600-ton (bm), for the Newfoundland trade. She and , built in 1794, were the largest ships built in Scotland in their years. They marked the beginning of increased activity by Scott & Co., particularly with respect to large, ocean-going ships. C. G. Scott started building at Cartsdyke Dockyard in 1850, as Scott & Company.

Still Steam-gasoline Engine
A still is an apparatus used to distillation, distill liquid mixtures by heating to selectively Boiling, boil and then cooling to Condensation, condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol. Application Since ethanol boiling point, boils at a much lower temperature than water, simple distillation can separate ethanol from water by applying heat to the mixture. Historically, a copper vessel was used for this purpose, since copper removes undesirable sulfur-based compounds from the alcohol. However, many modern stills are made of stainless steel pipes with copper linings to prevent erosion of the entire vessel and lower copper levels in the waste product (which in large distilleries is processed to be ...
