Alexander Lambert (diver)
The Severn Tunnel ( cy, Twnnel Hafren) is a railway tunnel in the United Kingdom, linking South Gloucestershire in the west of England to Monmouthshire in south Wales under the estuary of the River Severn. It was constructed by the Great Western Railway (GWR) between 1873 and 1886 for the purpose of dramatically shortening the journey times of their trains, passenger and freight alike, between South Wales and Western England. It has often been regarded as the crowning achievement of GWR's chief engineer Sir John Hawkshaw. Prior to the tunnel's construction, lengthy detours were necessary for all traffic between South Wales and Western England, which either used ship or a lengthy diversion upriver via . Recognising the value of such a tunnel, the GWR sought its development, tasking Hawkshaw with its design and later contracting the civil engineer Thomas A. Walker to undertake its construction, which commenced in March 1873. Work proceeded smoothly until October 1879, at which p ...

Cornish Engine
A Cornish engine is a type of steam engine developed in Cornwall, England, mainly for pumping water from a mine. It is a form of beam engine that uses steam at a higher pressure than the earlier engines designed by James Watt. The engines were also used for powering man engines to assist the underground miners' journeys to and from their working levels, for winching materials into and out of the mine, and for powering on-site ore stamping machinery. Background: The steam engine in Cornwall Cornwall has long had tin, copper and other metal ore mines, but if mining is to take place at greater depths, a means to dewater the mine must be found. Lifting the weight of water up from the depths requires great amounts of work input. This energy may be weakly supplied by horse power or a waterwheel to operate pumps, but horses have limited power and waterwheels need a suitable stream of water. Accordingly, the innovation of coal-fired steam power to work pumps was more versati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilning High Level Station Up Freight Geograph-2935954-by-Ben-Brooksbank
Pilning is a village in South Gloucestershire, England, close to Redwick and Severn Beach. Pilning is close to the M4, M49 and A403 roads, and has the South Wales Main Line railway running through it, with a minor station. The civil parish is ''Pilning'' and Severn Beach. The population at the 2011 census was 3,647. An electoral ward exists in the same name. Because of the close proximity of the River Severn and the English Stones section of the river bed, Pilning has found itself the ideal place to make both a substantial railway tunnel and motorway bridge. The Severn Tunnel opened in 1885 and the Second Severn Crossing opened in 1996. Landmarks The village is home to St Peters Primary School and a number of other amenities including a shop, a doctor's surgery, and several pubs such as The King's Arms. The Plough Inn hosts a jazz evening on the first Sunday of every month. Pilning Cricket Club was established in 1883. The parish church of St Peter was completed in 185 ...

RANSUM
The Royal Australian Navy School of Underwater Medicine (RANSUM) is an instructor-led training course based at Sydney, Australia. History Before 1961 medical support at the diving section of HMAS ''Watson'' was provided by the District Medical Officer, Surgeon Lieutenant Commander Shane A.C. Watson, whose interest in diving led to research in injuries related to marine animals. Medical Director-General of the Royal Australian Navy, Surgeon Rear Admiral Lionel Lockwood, recognized the need for a specialisation in diving medicine and appointed Surgeon Lieutenant Commander Rex Gray to service in Underwater Medicine. Dr. Gray was an anaesthesiologist and accepted this commission on 20 February 1961. Dr. Gray was trained as a diver and sent to England for seven months to learn about modern diving medicine. He visited the Royal Naval Medical School at Alverstoke, the R.N. Physiological Laboratory, the Submarine Training School at HMS Dolphin, Diving School HMS ''Vernon'', and th ...

Siebe Gorman
Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe , a German-born British engineer chiefly known for his contributions to diving equipment. Siebe plc started in the 1970s as a continuation of Siebe Gorman when Siebe Gorman started to take over other firms, to mean the new conglomerate to distinguish it from Siebe Gorman's original breathing apparatus and diving gear core business. Siebe plc was once one of the United Kingdom's largest engineering businesses. It was a constituent of the FTSE 100 Index but in 1999 it merged with BTR plc to form Invensys. Invensys was taken over by the French multinational Schneider Electric for £3.4 billion in January 2014.

Self-contained Breathing Apparatus
A self-contained breathing apparatus (SCBA), sometimes referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA), is a device worn to provide breathable air in an atmosphere that is immediately dangerous to life or health. They are typically used in firefighting and industry. The term ''self-contained'' means that the SCBA is not dependent on a remote supply of breathing gas (e.g., through a long hose). If designed for use under water, it is also known as a Scuba set (self-contained underwater breathing apparatus). When not used underwater, they are sometimes called industrial breathing sets. Unofficial names include ''air pack'', ''air tank'', ''oxygen cylinder'' or simply ''pack'', which are mostly used in firefighting. An SCBA typically has three main components: a high-pressure tank (e.g., , about 150 to 374 atmospheres), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mou ...

Henry Fleuss
Henry Albert Fleuss (13 June 1851 – 6 January 1933) was a pioneering diving engineer, and Master Diver for Siebe, Gorman & Co. of London. Fleuss was born in Marlborough, Wiltshire in 1851. In 1878 he was granted a patent which improved rebreathers. His apparatus consisted of a rubber mask connected to a breathing bag, with (estimated) 50-60% O2 supplied from a copper tank and CO2 scrubbed by rope yarn soaked in a solution of caustic potash, the system giving a duration of about three hours. Fleuss tested his device in 1879 by spending an hour submerged in a water tank, then one week later by diving to a depth of 5.5m in open water, upon which occasion he was slightly injured when his assistants abruptly pulled him to the surface. Fleuss's apparatus was first used under operational conditions in November 1880 by Alexander Lambert, lead diver of the Severn Tunnel construction project. Trained by Fleuss, he was able to close a submerged sluice door in the tunnel which had defea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennant Measures
The Pennant Measures is the traditional name for a sequence of sedimentary rocks of the South Wales Coalfield. They were also referred to as the Upper Coal Measures and assigned to the Westphalian 'C' and Westphalian 'D' stages of the Carboniferous Period. The Pennant Measures were divided into the Lower Pennant Measures and the Upper Pennant Measures, differing from the underlying Middle and Lower Coal Measures in being principally of sandstone units – known collectively as the Pennant Sandstone – with mudstone being the subsidiary rock type. Numerous coal seams occur within the Pennant Measures though they are less common than in the underlying Coal Measures.British Geological Survey 1:50,000 map sheet 231 'Merthyr Tydfil' & accompanying memoir. However recent reclassification of the sequence has resulted in the definition by the British Geological Survey of the Pennant Sandstone Formation as a sub-unit of the newly established Warwickshire Group. The formation is recogni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acts Of Parliament In The United Kingdom
In the United Kingdom an act of Parliament is primary legislation passed by the Parliament of the United Kingdom. An act of Parliament can be enforced in all four of the UK constituent countries ( England, Scotland, Wales and Northern Ireland); however as a result of devolution the majority of acts that are now passed by Parliament apply either to England and Wales only, or England only; whilst generally acts only relating to constitutional and reserved matters now apply to the whole of the United Kingdom. A draft piece of legislation is called a bill; when this is passed by Parliament and given Royal Assent, it becomes an act and part of statute law. Classification of legislation Acts of Parliament are classified as either "public general acts" or "local and personal acts" (also known as "private acts"). Bills are also classified as "public", "private", or "hybrid". Public general acts Public general acts form the largest category of legislation, in princ ...
