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 ...

Chance Bros
Chance Brothers and Company was a glassworks originally based in Spon Lane, Smethwick, West Midlands (county), West Midlands (formerly in Staffordshire), in England. It was a leading glass manufacturer and a pioneer of British glassmaking technology. The Chance family originated in Bromsgrove in Worcestershire as farmers and craftsmen, before setting up business in Smethwick in 1822. Situated between Birmingham and the Black Country in the agglomeration of the Midlands industrial heartland, they took advantage of the skilled workers, canals and many advances that were taking place in the industrial West Midlands (region), West Midlands at the time. Throughout its almost two centuries of history many changes affected the company which, now privatised, continues to function as Chance Glass Limited, a specialised industrial glass manufacturer in Malvern, Worcestershire at one of its small subsidiary factories. The social and economic impact of the company on the region is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Day Labour
Day labor (or day labour in Commonwealth spelling) is work done where the worker is hired and paid one day at a time, with no promise that more work will be available in the future. It is a form of contingent work. Types Day laborers (also known archaically as ''daysmen'' ) find work through three common routes. Firstly, some employment agencies specialize in very short-term contracts for manual labor most often in construction, factories, offices, and manufacturing. These companies usually have offices where workers can arrive and be assigned to a job on the spot, as they are available. Secondly, a manager looking for additional labor to fill an unexpected change in plans is presented with a problem of finding the needed quantity of labor with the right skills. Imagine the magnitude of the task of looking for workers, on the side of the street or by calling various employment agencies, who can verify that they are journeyman asphalt rakers, typists, programmers, etc. The ben ...

Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for ex ...

Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wyong Shire Council
Wyong Shire was a local government area located in the Central Coast region of New South Wales, Australia. The incorporation of the Wyong area dates back to 7 March 1906 when the entire area of the Brisbane Water Police District outside of the Town of Gosford was proclaimed as the Erina Shire. From 1 January 1947, local government in the Central Coast region was reorganised, creating ''Gosford Shire'' and ''Wyong Shire'', which comprised Erina Shire north and east of Kulnura, Central Mangrove and Lisarow. Until its abolition in 2016, Wyong Shire was located around the coastal lake system of Tuggerah Lake, Budgewoi Lake and Lake Munmorah. The area included a coastal strip from Bateau Bay to Budgewoi, some lakeside towns and residential areas, some inland towns on the coastal plain and a sparsely populated region to the west with the rural townships of Yarramalong, Dooralong, Jilliby, and regions of native bush surrounding Kulnura. Wyong Shire's administrative centre was locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsten-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 ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...
