Royal Sovereign Lighthouse
Royal Sovereign lighthouse, located offshore from Eastbourne, is a decommissioned lighthouse marking the Royal Sovereign shoal, a sandbank named after HMS Sovereign of the Seas, HMS ''Royal Sovereign''. Its distinctive shape is easily recognised as it comprises a large platform (which functions as a helicopter deck) supported by a single pillar rising out of the water. Originally, the platform was manned by three full-time keepers, accommodation being contained in the 'cabin section' immediately below the platform. Additional accommodation was provided for up to four visiting maintenance workers. Construction and installation The lighthouse replaced a Lightvessel, lightship that had marked the Royal Sovereign Shoal since 1875. The structure was built, in two parts, on Newhaven, East Sussex, Newhaven beach, and put into position in 1970. First, the base and attached column were floated out to the shoal, where the hollow base was flooded and allowed to sink into position. Then t ...

Eastbourne
Eastbourne () is a town and seaside resort in East Sussex, on the south coast of England, east of Brighton and south of London. Eastbourne is immediately east of Beachy Head, the highest chalk sea cliff in Great Britain and part of the larger Eastbourne Downland Estate. The seafront consists largely of Victorian hotels, a pier, theatre, contemporary art gallery and a Napoleonic era fort and military museum. Though Eastbourne is a relatively new town, there is evidence of human occupation in the area from the Stone Age. The town grew as a fashionable tourist resort largely thanks to prominent landowner, William Cavendish, later to become the Duke of Devonshire. Cavendish appointed architect Henry Currey to design a street plan for the town, but not before sending him to Europe to draw inspiration. The resulting mix of architecture is typically Victorian and remains a key feature of Eastbourne. As a seaside resort, Eastbourne derives a large and increasing income from ...

Diaphone
The diaphone is a noisemaking device best known for its use as a foghorn: It can produce deep, powerful tones, able to carry a long distance. Although they have fallen out of favor, diaphones were also used at some fire stations and in other situations where a loud, audible signal was required. History The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides; the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, high-pressure air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would repeat. A ...

Buildings And Structures In East Sussex
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Completed In 1971
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beachy Head Lighthouse
Beachy Head Lighthouse is a lighthouse located in the English Channel below the cliffs of Beachy Head in East Sussex. It is in height and became operational in October 1902. It was the last traditional-style 'rock tower' (i.e. offshore lighthouse) to be built by Trinity House. Construction Beachy Head Lighthouse was built to replace the Belle Tout Lighthouse on top of the cliffs of Beachy Head, which was completed in 1834. This was not as successful as had been hoped, as its light was frequently obscured by sea mists. Thus it was decided to build a replacement at the foot of the cliffs. Belle Tout lighthouse was decommissioned in 1902, and still exists as a holiday home. In 1900 to 1902 under the direction of Sir Thomas Matthews, the Trinity House Engineer-in-Chief, Beachy Head Lighthouse was built, sited about 165 metres seawards from the base of the cliffs. For the construction, a temporary cable car from the cliff was installed for the transport of workers and stones to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

East Sussex
East Sussex is a ceremonial and non-metropolitan county in South East England on the English Channel coast. It is bordered by Kent to the north and east, West Sussex to the west, and Surrey to the north-west. The largest settlement in East Sussex is the city of Brighton and Hove. History East Sussex is part of the historic county of Sussex, which has its roots in the ancient kingdom of the South Saxons, who established themselves there in the 5th century AD, after the departure of the Romans. Archaeological remains are plentiful, especially in the upland areas. The area's position on the coast has also meant that there were many invaders, including the Romans and later the Normans. Earlier industries have included fishing, iron-making, and the wool trade, all of which have declined, or been lost completely. Governance Sussex was historically sub-divided into six rapes. From the 12th century the three eastern rapes together and the three western rapes together had separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Order Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.
