Pite-Rönnskär
Pite-Rönnskär is a Swedish island with lighthouse station located in the Bothnian Bay. The island is located at the border between the provinces of Västerbotten and Norrbotten but belongs to Skellefteå Municipality. The island was a well known fishing village for many years and contains a chapel dating from 1771. In 1821 a pilot station was located on the island. Today the fishing cabins on the island is used as summer residences. The island has a weather station, and wind observations from it is reported by the Swedish Meteorological and Hydrological Institute in their shipping forecast. Lighthouse The first lighthouse on the island was lit in 1880. It was built on the gable of a keeper's house and carried a kerosene lamp. In 1905 the current lighthouse was constructed on the island. It was first built in 1862 as one of two lighthouses at the Sandhammaren light station in Scania. When it was relocated the current fresnel lens and a gas mantle light was installed. It was replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandhammaren
Sandhammaren is a Swedish lighthouse, and the name of both a beach and a point east of Ystad in Scania. At first two identical lighthouses were constructed, because it was a risk to mistake this lighthouse with the one on Ertholmene. The flame first ran on colza oil. Later on (1891), one of the lighthouses was put out of service and moved to Pite-Rönnskär in Norrland, at the same time the lamp was transformed to a paraffin lamp. The lighthouse was electrified in 1952. The Swedish Maritime Administration owns and runs the lighthouse.

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens (optics), lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. The simpler Dioptrics, dioptric (purely refraction, refractive) form of the lens was first proposed by Georges-Louis Leclerc, Comte de Buffon, and independently reinvented by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. The Catadioptric system, catadioptric (combining refraction and reflection) form of the lens, entirely invented by Fresnel, has outer Prism (optics), prismatic elements that use total internal reflection as well as refraction to capture more oblique light from the light source and add it to the beam, making it visible at greater distances. 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 ...

Gustaf Von Heidenstam
Nils ''Gustav'' von Heidenstam (1822 – 2 June 1887) was a Swedish engineer born in Blekinge. He was the chief engineer of the Swedish Royal Coast Guard. Life He was the son of Werther Werner von Heidenstam (16 October 1763 – 1852) and father of Verner von Heidenstam (1859–1940), poet, novelist and laureate of the Nobel Prize in Literature in 1916. The mid-19th century was a period of intensive lighthouse-building. The work to cover Sweden's coasts with lighthouses was led by lighthouse engineer Gustav von Heidenstam at the Swedish Board of Pilotage. He designed the type of lighthouse of which Pater Noster is an example, which is often called 'Heidenstammare'. Of a total of eleven lighthouses of this type, ten still remain. When Heidenstam created the lighthouse Pater Noster, he got his inspiration by studying the English lighthouse Maple Sound in the mouth of the Thames The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows ...

Swedish Maritime Administration
The Swedish Maritime Administration () is the government agency in Sweden which provides services to the transport sector by keeping the sea lanes open and safe. The agency is to a certain degree financed through fees levied on commercial shipping. The main services of the Maritime Administration include: pilotage, maintenance of marine fairways, ice-breaking, hydrographics, maritime search and rescue, seamen's service. It also maintains the lighthouses and other aids to navigation of Sweden. Until 1 January 2009, it also was responsible for maritime safety inspection. Seagoing vessels navigating the Baltic Sea must meet certain ice class requirement. While its mainly deals with merchant shipping, other maritime activities are also taken into account. Sjöfartsverket runs the Joint Rescue Center Gothenburg.

Dalén Light
A Dalén light is a flashing light produced from burning of carbide gas (acetylene), combined with a solar sensor which automatically operates the light only during darkness. Overview In the last quarter of the 19th century navigation buoys began to be illuminated, however at first the lights were fixed (continuous) and could be mistaken for ship's navigation lights. Gustaf Dalén invented a valve which could be adjusted to deliver pulses of acetylene into the lamp. A pilot light, which burns continuously, then ignited them. The pattern of flashes (known as the light's ''characteristic'') can be set by screw adjustments. The invention of this system resulted in Dalén being awarded the 1912 Nobel Prize in Physics. Gas was wasted however due to illumination during the day and subsequently Dalén developed the sun valve to shut off the flashes during daylight. The technology was a form of light source in lighthouses from the 1900s through the 1960s, when electric lighting had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Mantle
A Coleman white gas lantern mantle glowing at full brightness An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. ''Mantle'' refers to the way it hangs like a cloak above the flame. Gas mantles are also used in some portable camping lanterns, pressure lanterns and some oil lamps. Gas mantles are usually sold as a fabric bag which, because of impregnation with metal nitrates, burns away to leave a rigid but fragile mesh of metal oxides when heated during initial use; these metal oxides produce light from the heat of the flame whenever used. Thorium dioxide was commonly a major component; being radioactive, it has led to concerns about the safety of those involved in manufacturing mantles. Normal use, however, poses minimal health risk.

Scania
Scania ( ), also known by its native name of Skåne (), is the southernmost of the historical provinces of Sweden, provinces () of Sweden. Located in the south tip of the geographical region of Götaland, the province is roughly conterminous with Skåne County, created in 1997. Like the other historical provinces of Sweden, Scania still features in colloquial speech and in cultural references, and can therefore not be regarded as an archaic concept. Within Scania there are 33 municipalities of Sweden, municipalities that are autonomous within the Skåne Regional Council. Scania's largest urban areas of Sweden, city, Malmö, is the third-largest city in Sweden, as well as the fifth-largest in Scandinavia. To the north, Scania borders the historical provinces of Halland and Småland, to the northeast Blekinge, to the east and south the Baltic Sea, and to the west Öresund. Since 2000, a road and railway bridge, the Öresund Bridge, bridges the Öresund, Sound and connects Scania ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Västerbotten
Västerbotten (), sometimes called West Bothnia or Westrobothnia, is a province (''landskap'') in northern Sweden, located by the Gulf of Bothnia. It borders the provinces of Ångermanland, Lapland and Norrbotten. The region is famous for Västerbotten cheese. Administration The traditional provinces of Sweden have no administrative or political functions; instead, they are purely historical and cultural entities. The administrative units are the counties. Västerbotten County encompasses the province of Västerbotten as well as the southern part of Swedish Lapland. Heraldry On 18 January 1884, all Swedish provinces were granted the status of duchies, allowing their coats of arms to be displayed with a ducal coronet. The coat of arms for Västerbotten is described as: "Azure Seme of Mullets Or a Reindeer in full course and hoofed Gules." Geography Västerbotten was historically divided into chartered cities and districts. Cities *Umeå (1622) *Skellefteå (1845) Muni ...

Gable
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The term gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roof do not have a gable (for example hip roofs do not). One common type of roof with gables, the 'gable roof', is named after its prominent gables. A parapet made of a series of curves (shaped gable, see also Dutch gable) or horizontal steps (crow-stepped gable) may hide the diagonal lines of the roof. Gable ends of more recent buildings are often treated in the same way as the Classic pediment form. But unlike Classical structures, which operate through post and lintel, trabeation, the gable ends of many buildings are actually bearing-wall structures. Gable style is also used in the design of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
