South Solitary Island Light
South Solitary Island Light is an active lighthouse on South Solitary Island, an island within the Solitary Islands Marine Park, about northeast of Coffs Harbour, New South Wales, Australia. The lighthouse is located at the summit of the island. It is considered the most isolated lighthouse on the New South Wales coast. It was first in New South Wales to use kerosene over colza oil, and the last to do so before converting to electric power. History Suggestions for a lighthouse near Coffs Harbour were made as early as 1856, with locations proposed on either North Solitary Island or South Solitary Island. It was the shipmasters' preference that set the location to be South Solitary. The lighthouse was designed by Colonial Architect James Barnet, and it is one of three concrete lighthouses built during that period, the others being Smoky Cape Lighthouse and Green Cape Lighthouse. Barnet had visited the island in October 1877, to determine the best locations for the building ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bellingen, New South Wales
Bellingen ( ) is a small town in the Mid North Coast of New South Wales, Australia. It is located on Waterfall Way on the Bellinger River, approximately halfway between the major Australian cities of Sydney and Brisbane. In 2021, the population of Bellingen was 13,253, and it is the council seat of Bellingen Shire. History The Bellinger Valley was first settled by Kooris – the Gumbaynggir people. The first European to come across the Bellinger Valley was the stockman William Myles who arrived in 1840 looking for new valleys north of Kempsey and the Macleay River. The following year, Myles returned accompanied by government surveyor Clement Hodgkinson. Hodgkinson decided to name the area after the word that the Gumbaynggir people in the area used for the river, "Billingen", pronounced like "Billing-en". When it came time to write the word, the Aboriginal voice and the European ear combined to give the spelling of "Bellingen", and over time usage has altered the pronunciation ...

Distance Education
Distance education, also known as distance learning, is the education of students who may not always be physically present at a school, or where the learner and the teacher are separated in both time and distance. Traditionally, this usually involved correspondence courses wherein the student corresponded with the school via mail. Distance education is a technology mediated modality and has evolved with the evolution of technologies such as video conferencing, TV, and internet. Today, it usually involves online education and the learning is usually mediated by some form of technology. A distance learning program can be completely distance learning, or a combination of distance learning and traditional classroom instruction (called hybrid or Blended learning, blended). Other modalities include distance learning with complementary virtual environment or teaching in virtual environment (e-learning). Massive open online courses (MOOCs), offering large-scale interactive participation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governess
A governess is a largely obsolete term for a woman employed as a private tutor, who teaches and trains a child or children in their home. A governess often lives in the same residence as the children she is teaching. In contrast to a nanny, the primary role of a governess is teaching, rather than meeting the physical needs of children; hence a governess is usually in charge of school-aged children, rather than babies. The position of governess used to be common in affluent European families before the First World War, especially in the countryside where no suitable school existed nearby and when parents preferred to educate their children at home rather than send them away to boarding school for months at a time—varied across time and countries. Governesses were usually in charge of girls and younger boys. When a boy was old enough, he left his governess for a tutor or a school. Governesses are rarer now, except within great house, large and wealthy households or royal famil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bendix Corporation
Bendix Corporation is an American manufacturing and engineering company which, during various times in its existence, made automotive brake shoes and systems, vacuum tubes, aircraft brakes, aeronautical hydraulics and electric power systems, avionics, aircraft and automobile fuel control systems, radios, televisions and computers. It was also well known for the name ''Bendix'', as used on home clothes washing machines, but never actually made these appliances. History Early history Founder and inventor Vincent Bendix initially began his corporation in a hotel room in Chicago in 1914 with an agreement with the struggling bicycle brake manufacturing firm, Eclipse Machine Company of Elmira, New York. Bendix granted permission to his invention which was described as "a New York device for the starting of explosive motors." This company made a low cost triple thread screw which could be used in the manufacture of other drive parts. By using this screw with the Eclipse Machine Com ...

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 ...

Pedal Radio
Human power is work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans. World records of power performance by humans are of interest to work planners and work-process engineers. The average level of human power that can be maintained over a certain duration of time is interesting to engineers designing work operations in industry. Human-powered transport includes bicycles, rowing, skiing and many other forms of mobility. Human-powered equipment is occasionally used to generate, and sometimes to store, electrical energy for use where no other source of power is available. These include the Gibson girl survival radio, wind-up or (clockwork) radio and pedal radio. Available power Normal human metabolism produces heat at a basal metabolic rate of around 80 watts. During a bicycle race, an elite cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliograph
A heliograph () is a semaphore system that signals by flashes of sunlight (generally using Morse code) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter. The heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century. Its main uses were military, survey and forest protection work. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975. Description There were many heliograph types. Most heliographs were variants of the British Army Mance Mark V version (Fig.1). It used a mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Lamp
Signal lamp training during World War II A signal lamp (sometimes called an Aldis lamp or a Morse lamp) is a semaphore system using a visual signaling device for optical communication, typically using Morse code. The idea of flashing dots and dashes from a lantern was first put into practice by Captain Philip Howard Colomb, of the Royal Navy, in 1867. Colomb's design used limelight for illumination, and his original code was not the same as Morse code. During World War I, German signalers used optical Morse transmitters called ', with a range of up to 8 km (5 miles) at night, using red filters for undetected communications. Modern signal lamps produce a focused pulse of light, either by opening and closing shutters mounted in front of the lamp, or by tilting a concave mirror. They continue to be used to the present day on naval vessels and for aviation light signals in air traffic control towers, as a backup device in case of a complete failure of an aircraft's radi ...

Launch (boat)
Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard. In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces. Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally, these were decked boats, some of which were capable of fast speeds. A powered boat operated by a regulatory or official organisation may be termed a lau ...

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...
