Point Perpendicular Light
Point Perpendicular Light is a lighthouse located on Point Perpendicular, a point at the southern tip of the Beecroft Peninsula, in New South Wales, Australia. It marks and the northern entrance to Jervis Bay. The historic lighthouse was active from 1889 to 1993 and is still present, though its future is unclear. It is believed to be the first lighthouse in New South Wales which was built of precast concrete blocks. The light was replaced in 1993 with a skeletal tower which is active. History Point Perpendicular Lighthouse was built to replace Cape St George Lighthouse which was inadequately located on the southern entrance to Jervis Bay, a fact which was apparent since its construction in 1860. Suggested places for replacing the light were on Bowen Island or Crocodile Head. Point Perpendicular was chosen in September 1883 by Colonial Architect James Barnet and Captain Francis Hixson of the Marine Board. The plans for the lighthouse were signed on 18 March 1897.

Norah Head Light
Norah Head Light is an active lighthouse located at Norah Head, a headland on the Central Coast, New South Wales, Australia, close to Toukley. It is the last lighthouse of the James Barnet style to be built, and the last staffed lighthouse constructed in New South Wales. Officially displayed for the first time in 1903, the original vaporized kerosene burner was upgraded in 1923, electrified in 1961 and automated and demanned in 1994, after more than 90 years of being staffed. It celebrated its centenary in 2003. The concrete block tower is high, topped by a bluestone gallery. On top of the gallery is the original Chance Bros. lantern. This lantern holds the original housing of the Chance Bros. 1st order bivalve dioptric Fresnel lens. Other important structures include the chief lightkeeper's cottage and assistant keeper's duplex, and a flag house. History Calls for construction of a lighthouse at Norah Head (then "Bungaree Noragh Point") were made as early as 1861 due to m ...

Lighthouse Keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...

Waratah
Waratah (''Telopea'') is an Australian-endemic genus of five species of large shrubs or small trees, native to the southeastern parts of Australia (New South Wales, Victoria, and Tasmania). The best-known species in this genus is ''Telopea speciosissima'', which has bright red flowers and is the New South Wales (NSW) state emblem. The waratah is a member of the family Proteaceae, flowering plants distributed in the Southern Hemisphere. The key diagnostic feature of Proteaceae is the inflorescence, which is often very large, brightly coloured and showy, consisting of many small flowers densely packed into a compact head or spike. Species of waratah boast such inflorescences ranging from 6–15 cm in diameter with a basal ring of coloured bracts. The leaves are spirally arranged, 10–20 cm long and 2–3 cm broad with entire or serrated margins. The name ''waratah'' comes from the Eora Aboriginal people, the pre-European inhabitants of the Sydney area. Taxonomy The genus ''Telopea ...

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] |
Scaffolding
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects. There are five main types of scaffolding used worldwide today. These are tube and coupler (fitting) components, prefabricated modular system scaffold components, H-frame / façade modular system scaffolds, timber scaffolds and bamboo scaffolds (particularly in China and India). Each type is made from several components which often include: * A base jack or plate which is a load-bearing base for the ...

Formwork
Formwork is Molding (process), molds into which concrete or similar materials are either precast concrete, precast or cast-in-place concrete, cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure. Types Formwork may be made of wood, metal, plastic, or composite materials: #''Traditional timber formwork''. The formwork is built on site out of timber and plywood or moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring reusable formwork. It is also the most flexible type of formwork, so even where other systems are in use, complicated sections may use it. #''Engineered Formwork System''. Th ...

Department Of Defence (Australia)
Defence Australia is a department of the Government of Australia charged with the responsibility to defend Australia and its national interests. Along with the Australian Defence Force (ADF), it forms part of the Australian Defence Organisation (ADO) and is accountable to the Commonwealth Parliament, on behalf of the Australian people, for the efficiency and effectiveness with which it carries out the Government's defence policy. The head of the department, who leads it on a daily basis, is the Secretary of the Department of Defence (SECDEF), currently Greg Moriarty. The Secretary reports to the Minister of Defence, Richard Marles. History Australia has had at least one defence-related government department since Federation in 1901. The first Department of Defence existed from 1901 until 1921. In 1915, during World War I, a separate Department of the Navy was created. The two departments merged in 1921 to form the second Department of Defence, regarded as a separate bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz Halogen Lamp
A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine. The combination of the halogen gas and the tungsten filament produces a halogen-cycle chemical reaction, which redeposits evaporated tungsten on the filament, increasing its life and maintaining the clarity of the envelope. This allows the filament to operate at a higher temperature than a standard incandescent lamp of similar power and operating life; this also produces light with higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination. The small glass envelope may be enclosed in a much larger outer glass bulb, which has a lower temperature, protects the inner bulb from contamination, and mak ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...
