Crowdy Head Light
Crowdy Head Light is an active lighthouse located at Crowdy Head, a headland between Forster and Port Macquarie, New South Wales, Australia. It is registered with the Register of the National Estate. History The first station in the area was a pilot station established in 1860 at nearby Harrington, assisting ships navigating the entrance of the Manning River. The current lighthouse is the last of five lighthouses of similar design designed and built by James Barnet in 1878–80, the other four being Fingal Head Light, Clarence River Light (now demolished), Tacking Point Lighthouse and Richmond River Light. The original light was a fixed white light from a 4th order catadioptric apparatus with an intensity of less than 1,000 cd. It was manned by one keeper. In 1928 the apparatus was converted to a carbide lamp (acetylene gas), with an intensity of 1,500 cd. At the same opportunity, the light was automated. The pilot station was closed in the 1960s. In 1972 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clarence River Light
Clarence River Light, also known as Yamba Light or Clarence Head Light, is an active lighthouse located on Pilot Hill, a hill in Wooli Park, Yamba, New South Wales, Australia, south of the entrance of Clarence River. The current lighthouse was built in 1955, replacing a previous lighthouse built in 1880. It serves as the rear range light for two different ranges. History Old lighthouse The first light on Pilot Hill was most probably a platform with a kerosene lamp, located on the eastern part of the hill. The first actual structure was a small wooden hut built in 1866 with a large kerosene lamp placed on a bench. It was located where the 1880 lighthouse was later built, at . The mast from this lighthouse is on display at the Story House Museum in Yamba. In 1878 tenders were called for a permanent lighthouse, one of five lighthouses of similar design designed by James Barnet in 1878–80, the other four being Fingal Head Light, Crowdy Head Light, Tacking Point Lighthouse an ...

Corbel
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England. The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or parapet, has been used since Neolithic (New Stone Age) times. It is common in medieval architecture and in the Scottish baronial style as well as in the vocabulary of classical architecture, such as the modillions of a Corinthian cornice. The corbel arch and corbel vault use the technique systematically to make openings in walls and to form ceilings. These are found in the early architecture of most cultures, from Eurasia to Pre-Columbian architecture. A console is more specifically an "S"-shaped scroll bracket in the classic ...

Bluestone
Bluestone is a cultural or commercial name for a number of dimension or building stone varieties, including: * basalt in Victoria, Australia, and in New Zealand * dolerites in Tasmania, Australia; and in Britain (including Stonehenge) * feldspathic sandstone in the US and Canada * limestone in the Shenandoah Valley in the US, from the Hainaut quarries in Soignies, Belgium, and from quarries in County Carlow, County Galway and County Kilkenny in Ireland * slate in South Australia Stonehenge The term "bluestone" in Britain is used in a loose sense to cover all of the "foreign," not intrinsic, stones and rock debris at Stonehenge. It is a "convenience" label rather than a geological term, since at least 46 different rock types are represented. One of the most common rocks in the assemblage is known as Preseli Spotted Dolerite—a chemically altered igneous rock containing spots or clusters of secondary minerals replacing plagioclase feldspar. It is a medium grained dark and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Jersey
New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At , New Jersey is the fifth-smallest state in land area; but with close to 9.3 million residents, it ranks 11th in population and first in population density. The state capital is Trenton, and the most populous city is Newark. With the exception of Warren County, all of the state's 21 counties lie within the combined statistical areas of New York City or Philadelphia. New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized control o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Girt Light
The Sea Girt Light is a lighthouse marking the inlet leading to the Wreck Pond in Sea Girt in Monmouth County, New Jersey, United States. It hosted the first radio beacon mounted in a shore installation in the United States. History The New Jersey shore between the Barnegat and Navesink lighthouses, a distance of nearly 40 miles, was unlit in the 1800s, and in 1888 the Lighthouse Board requested funds to establish a light in this area. The original site was to be at Manasquan Inlet, just to the south of Sea Girt; however, the site was found to be unsuitable and the present lot was obtained on the beach at Sea Girt, near Wreck Pond. An L-shaped brick house with an integral tower was constructed, and the light was first exhibited in December 1896. This was the last shore lighthouse with an integral keeper's residence built on the east coast of the United States. Moving sand and erosion were problems from early on, but fencing in 1900 and steel pilings in the 1920s arrested the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mains Electricity
Mains electricity or utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world. People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable plugs and sockets in different regions provide some protection from accidental use of appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbide Lamp
Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C2H2) which is created by the reaction of calcium carbide (CaC2) with water (H2O). Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by cavers, hunters, and cataphiles. Small carbide lamps called "carbide candles" or "smokers" are used for blackening rifle sights to reduce glare. They are sometimes referred to as "smokers" because of the sooty flame produced by acetylene. Mechanism A mining or caving lamp has calcium carbide placed in a lower chamber, the generator. The upper reservoir is then filled with water. A threaded valve or other mechanism is used to control the rate at which the water is allowed to drip into the chamber containing the calcium carbide.
