Bathurst Basin
Bathurst Basin is a small triangular basin adjoining the main harbour of the city of Bristol, England. The basin takes its name from Charles Bathurst, who was a Bristol MP in the early 19th century. The basin was built on an area of an old mill pond, Trin Mills. The pond was supplied by the River Malago, from Bedminster to the South. It lost its water supply as the New Cut was created in 1809, running to the South of the enlarged Floating Harbour and catching the flow of the Malago. After this it formed a connecting basin, through two sets of locks, between the Floating Harbour and the tidal River Avon in the New Cut. The connection enabled smaller vessels to bypass the main entrance locks in Cumberland Basin. From 1865 a deep water dock with a stone quay front was built. The area used to be an industrial dock with warehouses and numerous shipyards at the adjoining Wapping Shipyard and Docks, including Hilhouse, William Scott & Sons and William Patterson. Now there is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
050123 28 Bristol Lightship
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...

Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public House
A pub (short for public house) is a kind of drinking establishment which is licensed to serve alcoholic drinks for consumption on the premises. The term ''public house'' first appeared in the United Kingdom in late 17th century, and was used to differentiate private houses from those which were, quite literally, open to the public as "alehouses", "taverns" and "inns". By Georgian times, the term had become common parlance, although taverns, as a distinct establishment, had largely ceased to exist by the beginning of the 19th century. Today, there is no strict definition, but CAMRA states a pub has four characteristics:GLA Economics, Closing time: London's public houses, 2017 # is open to the public without membership or residency # serves draught beer or cider without requiring food be consumed # has at least one indoor area not laid out for meals # allows drinks to be bought at a bar (i.e., not only table service) The history of pubs can be traced to Roman taverns in B ...

Lightvessel
A lightvessel, or lightship, is a ship that acts as a lighthouse. They are used in waters that are too deep or otherwise unsuitable for lighthouse construction. Although some records exist of fire beacons being placed on ships in Roman times, the first modern lightvessel was off the Nore sandbank at the mouth of the River Thames in England, placed there by its inventor Robert Hamblin in 1734. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others. Construction A crucial element of lightvessel design is the mounting of a light on a sufficiently tall mast. Initially, it consisted of oil lamps that could be run up the mast and lowered for servicing. Later vessels carried fixed lamps which were serviced in place. Fresnel lenses were used as they became available, and many vessels housed them in small versions of the lanterns used in lighthouses. Some lightship ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Float
A fireboat or fire-float is a specialized watercraft with pumps and nozzles designed for fighting shoreline and shipboard fires. The first fireboats, dating to the late 18th century, were tugboats, retrofitted with firefighting equipment. Older designs derived from tugboats and modern fireboats more closely resembling seafaring ships can both be found in service today. Some departments would give their multi-purpose craft the title of "fireboat" also. They are frequently used for fighting fires on docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an effectively unlimited supply of water available, pumping directly from below the hull. Fireboats can be used to assist shore-based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the 1989 Loma Prieta earthquake. Some modern firebo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welsh Back, Bristol
Welsh Back is a wharf and street alongside the floating harbour in the centre of the city of Bristol, England. The wharf and street extend some along the west side of the harbour between Bristol Bridge and Redcliffe Bridge. At the northern (Bristol Bridge) end, the street and wharf are immediately adjacent, but to the south they are separated by a range of single story transit sheds. The wharf is a grade II listed structure and takes its name because it was freqented by vessels from Welsh ports. The Welsh Back has been an important quay since the 13th century, when it was located on the tidal course of the River Avon. In 1475, the merchant and benefactor Alice Chestre is recorded as having given a crane for use at the Welsh Back, this being the first evidence of a crane in the port of Bristol. The quayside was extended in 1724, and in 1809 the floating harbour was created by impounding the former river channel, meaning that boats could stay afloat at all states of the tide ...

Brislington
Brislington is an area in the south east of the city of Bristol, England. It is on the edge of Bristol and from Bath. Brislington Brook runs through the area in the woodlands of Nightingale Valley and St Anne's Wood. Brislington formerly housed the HTV West Studios on Bath Road, and this is situated next to the historic Arnos Vale Cemetery, other notables landmarks include Brislington House and the 15th-century St Luke's Church. During the 18th–19th century, Brislington was regarded as a picturesque country village and contained many country homes. History The parish of Brislington was historically part of the Keynsham Hundred in Somerset. Brislington is also near to the site of the now demolished chapel of St. Anne's-in-the Wood (actually in nearby St Anne's), erected by one of the Lords de la Warr, whose family held the manor of Brislington from the late 12th to the mid-16th century; in the 15th century the chapel was a place of pilgrimage, visited by Henry VII). ...

Coal Tar
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It is a type of creosote. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railroad tie preservative and used in the surfacing of roads. Coal tar was listed as a known human carcinogen in the first Report on Carcinogens from the U.S. Federal Government. Coal tar was discovered circa 1665 and used for medical purposes as early as the 1800s. Circa 1850, the discovery that it could be used as the main ingredient in synthetic dyes engendered an entire industry. It is on the World Health Organization's List of Essential Medicines. Coal tar is available as a generic medication and over the counter. Side effects include skin irritation, sun sensitivity, allergic reactions, and skin discoloration. ...

Naphtha
Naphtha ( or ) is a flammable liquid hydrocarbon mixture. Mixtures labelled ''naphtha'' have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions ''naphtha'' may also be crude oil or refined products such as kerosene. ''Nephi'' and ''naphthar'' are sometimes used as synonyms. It is also known as Shellite in Australia. Etymology The word ''naphtha'' is from Latin and Ancient Greek (νάφθα), derived from Middle Persian ''naft'' ("wet", "naphtha"), the latter meaning of which was an assimilation from the Akkadian ''napṭu'' (see Semitic relatives such as Arabic ''nafṭ'' petroleum" Syriac ܢܰܦܬܳܐ ''naftā'') and Hebrew נֵפְט ''neft'' (meaning petroleum). In Ancient Greek, it was used to refer to any sort of petroleum or pitch. There is a hypothesis that the word is connected with the name of the Indo-Iranian god Apam Napat, which occurs in Vedic and in Avestic; ...

Ketch
A ketch is a two- masted sailboat whose mainmast is taller than the mizzen mast (or aft-mast), and whose mizzen mast is stepped forward of the rudder post. The mizzen mast stepped forward of the rudder post is what distinguishes the ketch from a yawl, which has its mizzen mast stepped aft of its rudder post. In the 19th and 20th centuries, ketch rigs were often employed on larger yachts and working watercraft, but ketches are also used as smaller working watercraft as short as 15 feet, or as small cruising boats, such as Bill Hanna's Tahiti ketches or L. Francis Herreshoff's Rozinante and H-28. The name ketch is derived from ''catch''. The ketch's main mast is usually stepped further forward than the position found on a sloop. The sail plan of a ketch is similar to that of a yawl, on which the mizzen mast is smaller and set further back. There are versions of the ketch rig that only has a mainsail and a mizzen, in which case they are referred to as ''cat ketch''. More comm ...

Bulk-handling Crane
A bulk-handling Crane (machine), crane is one that, instead of a simple hook that can handle a range of slung loads, has an integral grab for lifting bulk cargoes such as coal, mineral ore etc. Where the grab is a two-piece hinged bucket, it is known as a shell grab or shell bucket. Working the grab requires extra cables from the crane jib, so requires a specialised design of crane throughout, not merely an attachment. Some grabs use 2 cables for lift and control, others use 4. In 1927, Stothert & Pitt of Bath, Somerset produced the first specialised bulk-handling crane. This was to unload coal at Barking Power Station#Barking A power station, Barking power station in London. The grab has to be selected so that the combined weight of grab and contents does not exceed the grabbing safe working load of the crane. The mass of the contents depends upon the properties of the product being handled; its density, flow characteristics, angle of repose, lump/grain size, purity (e.g. is it ...
