Mew Island Lighthouse
Mew Island Lighthouse is an active lighthouse within the Copeland Islands of County Down in Northern Ireland. The current 19th-century tower is the most recent in a series of lighthouses that have been built in the islands, which have helped to guide shipping around the archipelago and into Belfast Lough. A number of different fuels, including coal gas, paraffin, and diesel, have been used to power the lighthouse. In 2015, the Commissioners of Irish Lights, who operate the lighthouse, replaced the hyperradiant Fresnel lens optic with a flashing LED system that uses only solar power. This large optic was then preserved and is now on display in the Titanic Quarter of Belfast as a visitor attraction known as ''The Great Light''. Copeland Island The earliest lighthouse in the Copeland Islands was built on Lighthouse Island in 1711 and used coal burnt in a brazier mounted on a three-storey tower above a keeper's cottage. Other cottage lighthouses were established at Howth Head, Loop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Halpin
George Halpin (Sr.) (1779? – 8 July 1854), was a prominent civil engineer and lighthouse builder, responsible for the construction of much of the Port of Dublin, several of Dublin's bridges, and a number of lighthouses; he is considered the founding father of the Irish lighthouse service. His son, , was also a well-known lighthouse builder. Biography Very little is known of Halpin's early life, though it is known that his background was in the building trade rather than in engineering. In 1800, he was made the Inspector of Works for the Dublin Ballast Board (the predecessor to the Commissioners of Irish Lights), succeeding Francis Tunstall, and in this capacity was responsible for a number of works.Skempton, p. 293 One of these, the Bull Wall, along with associated projects, led to the creation of Bull Island in Dublin Bay, and enabled deep-draught ships to use the port for the first time.Skempton, p. 294 Halpin was appointed the Inspector of Lighthouses in 1810.

A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet.

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

Smethwick
Smethwick () is an industrial town in Sandwell, West Midlands, England. It lies west of Birmingham city centre. Historically it was in Staffordshire. In 2019, the ward of Smethwick had an estimated population of 15,246, while the wider built-up area subdivision has a population of 53,653. History It was suggested that the name Smethwick meant "smiths' place of work", but a more recent interpretation has suggested the name means "the settlement on the smooth land". Smethwick was recorded in the Domesday Book as ''Smedeuuich'', the ''d'' in this spelling being the Anglo-Saxon letter eth. Until the end of the 18th century it was an outlying hamlet of the south Staffordshire village of Harborne. Harborne became part of the county borough of Birmingham and thus transferred from Staffordshire to Warwickshire in 1891, leaving Smethwick in the County of Staffordshire. The world's oldest working engine, the Smethwick Engine, made by Boulton & Watt, originally stood near Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chance Brothers
Chance Brothers and Company was a glassworks originally based in Spon Lane, Smethwick, West Midlands (formerly in Staffordshire), in England.

The Great Light (night View), Titanic Quarter, Belfast (November 2018) (Geograph 5966944 By Albert Bridge)
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic ...

Gasometer
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap. Typical volumes for large gas holders are about , with diameter structures. Gas holders now tend to be used for balancing purposes to ensure that gas pipes can be operated within a safe range of pressures, rather than for actually storing gas for later use. Etymology Antoine Lavoisier devised the first gas holder, which he called a ''gazomètre'', to assist his work in pneumatic chemistry. It enabled him to weigh the gas in a pneumatic trough with the precision he required. He published his ''Traité Élémentaire de Chimie'' in 1789. James Watt Junior collaborated with Thomas Beddoes in constructing the pneumatic apparatus, a shortlived piece of medical equipment that incorporated a ''gaz ...

Cannel Coal
Cannel coal or candle coal is a type of bituminous coal, also classified as terrestrial type oil shale. Hutton(1987) Dyni (2006), pp. 3–4 Speight (2012), pp. 6–7 Due to its physical morphology and low mineral content cannel coal is considered to be coal but by its texture and composition of the organic matter it is considered to be oil shale. Han et al. (1999) Although historically the term cannel coal has been used interchangeably with boghead coal, a more recent classification system restricts cannel coal to terrestrial origin, and boghead coal to lacustrine environments. Composition Cannel coal is brown to black oil shale. It comes from resins, spores, waxes, and cutinaceous and corky materials of terrestrial vascular plants, in part from Lycopsid (scale tree). Cannel coal was accumulated in ponds and shallow lakes in peat-forming swamps and bogs of the Carboniferous age under oxygen-deficient conditions. Stach (1975), p. 428 Thus cannel coal seams are shallow and often fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
