Trwyn Du Lighthouse
Trwyn Du Lighthouse, also known as Penmon Lighthouse, is a lighthouse between Black Point near Penmon and Ynys Seiriol, or Puffin Island, at the eastern extremity of Anglesey, marking the passage between the two islands. History The first lighthouse was erected in 1838, at a price of £11,589. There had been a call for a light at this location for some years by master shipmen in the nearby city of Liverpool, especially after the steamer the '' Rothsay Castle'' ran aground and broke up on nearby Lavan Sands in 1831 with 130 people losing their lives. The present Lighthouse, built 1835–1838, is 29 metres (95') tall and was designed by James Walker. It was his first sea-washed tower, and a prototype for his more ambitious tower on the Smalls. The Lighthouse has a stepped-base designed to discourage the huge upsurge of waves that had afflicted earlier lighthouses on the site and reduce the force of the water at the bottom of the tower. Austere vertical walls, instead of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penmon, Anglesey
Penmon is a promontory, village and parish, ecclesiastical parish on the eastern tip of the Isle of Anglesey in Wales, about east of the town of Beaumaris. It is in the community (Wales), community of Llangoed. The Welsh placenames, name comes from cy, pen (which can mean "head", "end" or "promontory") and ''Anglesey#History, Môn'', which is the Welsh word for Anglesey. It is the site of a historic monastery and associated 12th-century church. Walls near the well next to the church may be part of the oldest remaining Christian building in Wales. Penmon also has an award-winning beach and the Anglesey Coastal Path follows its shores. Quarry, Quarries in Penmon have provided stone for many important buildings and structures, including Birmingham Town Hall and the two bridges that cross the Menai Strait. The area is popular with locals and visitors alike for its monuments, tranquillity, bracing air and fine views of Snowdonia to the south across the Menai Strait. History ...

Catadioptric
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as searchlights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric", such as surveillance catadioptric sensors. Early catadioptric systems Catadioptric combinations have been used for many early optical systems. In the 1820s, Augustin-Jean Fresnel developed several catadioptric lighthouse reflectors. Léon Foucault developed a catadioptric microscope in 1859 to counteract aberrations of using a lens to image objects at high power. In 1876 a French engineer, A. Mangin, invented what has come to be called the Mangin mirror, a concave glass reflector with the silver surface on the rear side of the glass. The two surfaces o ...

Grade II* Listed Buildings In Anglesey
In the United Kingdom, the term listed building refers to a building or other structure officially designated as being of special architectural, historical, or cultural significance; Grade II* structures are those considered to be "particularly important buildings of more than special interest". Listing was begun by a provision in the Town and Country Planning Act 1947. Once listed, strict limitations are imposed on the modifications allowed to a building's structure or fittings. In Wales, the authority for listing under the Planning (Listed Buildings and Conservation Areas) Act 1990 rests with Cadw.

Toll Road
A toll road, also known as a turnpike or tollway, is a public or private road (almost always a controlled-access highway in the present day) for which a fee (or ''toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance. Toll roads have existed in some form since antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, ...

Beaumaris
Beaumaris ( ; cy, Biwmares ) is a town and community on the Isle of Anglesey in Wales, of which it is the former county town of Anglesey. It is located at the eastern entrance to the Menai Strait, the tidal waterway separating Anglesey from the coast of North Wales. At the 2011 census, its population was 1,938. The community includes Llanfaes. History Beaumaris was originally a Viking settlement known as ("Port of the Vikings"), but the town itself began its development in 1295 when Edward I of England, having conquered Wales, commissioned the building of Beaumaris Castle as part of a chain of fortifications around the North Wales coast (others include Conwy, Caernarfon and Harlech). The castle was built on a marsh and that is where it found its name; the Norman-French builders called it , which translates as "fair marsh". The ancient village of Llanfaes, a mile to the north of Beaumaris, had been occupied by Anglo-Saxons in 818 but had been regained by Merfyn Frych, Ki ...

Holyhead Control Centre
The Holyhead Breakwater Lighthouse stands on the Holyhead Breakwater outside the Welsh port of Holyhead, Anglesey. History The structure, which was completed in 1873, was most likely designed by Victorian civil engineer John Hawkshaw after he took control of Holyhead harbour works in 1857. The lighthouse was the last major building completed on the breakwater. The three-storey black and white tower, unlike many contemporary lighthouses, is square. It measures on each side, is high and rests above the high-water mark. It has chamfered angles and a stepped plinth set on an oval platform on the breakwater. A square design was chosen because it made the living quarters more comfortable. Much of the original living accommodation inside remains intact. The tower's external features include a roll-moulded string-course projecting above the first floor level. There is also a moulded cornice which supports a walkway around a circular glass-housed light. The tower is surmounted by ...

Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Acetylene Lamp
Acetylene (systematic name: ethyne) is the chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Census Of 1881
The United Kingdom Census of 1881 recorded the people residing in every household on the night of Sunday 3 April 1881, and was the fifth of the UK censuses to include details of household members. Data recorded Details collected include: address, name, relationship to the head of the family, marital status, age at last birthday, gender, occupation, and place of birth. As with earlier censuses, the form asked whether any "lunatics", "imbeciles" or "idiots" lived in the household, causing the Registrar General to observe that: "It is against human nature to expect a mother to admit her young child to be an idiot, however much she may fear this to be true. To acknowledge the fact is to abandon all hope." The total population of England, Wales and Scotland was recorded as 29,707,207. Notable respondents included Winston Churchill, Karl Marx and Charles Darwin. Indexing The 1881 census was the first UK census to be indexed in its entirety. In the 1980s, in a project that has been ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
