Henry Sutton (inventor)
Henry Sutton (4 September 1855, Ballarat, Victoria – 28 July 1912) was an Australian designer, engineer, and inventor credited with contributions to early developments in electricity, aviation, wireless communication, photography and telephony. Branch is Sutton's great-granddaughter Early life Family Henry Sutton, the second of the eleven children of Richard Henry Sutton (1831 – 1876), and Mary Sutton (1835 – 1894), née Johnson, was born in a tent on the Ballarat goldfields on 4 September 1855. He had three brothers, with whom he was associated in the ''Sutton Brothers'' musical business originally centred on Ballarat,Sutton's Proprietary, Limited, ''The Ballarat Star'', (Saturday, 29 December 1900), p.1 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballarat
Ballarat ( ) () is a city in the Central Highlands of Victoria, Australia. At the 2021 census, Ballarat had a population of 111,973, making it the third-largest urban inland city in Australia and the third-largest city in Victoria. Within months of Victoria separating from the colony of New South Wales in 1851, gold was discovered near Ballarat, sparking the Victorian gold rush. Ballarat subsequently became a thriving boomtown that for a time rivalled Melbourne, the capital of Victoria, in terms of wealth and cultural influence. In 1854, following a period of civil disobedience in Ballarat over gold licenses, local miners launched an armed uprising against government forces. Known as the Eureka Rebellion, it led to the introduction of white male suffrage in Australia, and as such is interpreted as the origin of Australian democracy. The rebellion's symbol, the Eureka Flag, has become a national symbol. Proclaimed a city on 9 September 1870, Ballarat's prosperity, unlik ...

Sprengel Pump
The Sprengel pump is a vacuum pump that uses drops of mercury falling through a small-bore capillary tube to trap air from the system to be evacuated. It was invented by Hanover-born chemist Hermann Sprengel in 1865 while he was working in London. The pump created the highest vacuum achievable at that time, less than 1 μPa (approximately 1×10−11 atm). Operation The supply of mercury is contained in the reservoir on the left. It flows over into the bulb ''B'', where it forms drops which fall into the long tube on the right. These drops entrap between them the air in ''B''. The mercury which runs out is collected and poured back into reservoir on the left. In this manner practically all the air can be removed from the bulb ''B'', and hence from any vessel ''R'', which may be connected with ''B''. At ''M'' is a manometer which indicates the pressure in the vessel ''R'', which is being exhausted. Falling mercury drops compress the air to atmospheric pressure which is releas ...

Austral Otis
Austral Otis was a Melbourne engineering works established in 1887 on site of former Langlands foundry in Grant Street, South Melbourne. It was one of the largest manufacturers of elevators in Australia and continued as the Otis Elevator Company. Origin The company was initially formed in 1878 as Hughes, Pye & Rigby manufacturing mining plant, steam engines, elevators, wool & other hydraulic presses. It was incorporated as a public company in 1887 as The Austral Otis Engineering and Elevator Company Limited and in October 1893 changed its name to The Austral Otis Engineering Co Ltd. The company epitomised the boom era. It was founded with just £600 in capital, but by the end of the 1880s it employed 300 workers, producing pumping engines, mining machinery, hydraulic lifts and huge steam engines for the city's cable trams and first electric power stations. Austral Otis tendered the Victorian Government to produce two steam traction engines after starting up in 1880 as a general en ...

Resistive Opto-isolator
Resistive opto-isolator (RO), also called photoresistive opto-isolator, vactrol (after a genericized trademark introduced by Vactec, Inc. in the 1960s), analog opto-isolatorIn PerkinElmer literature. or lamp-coupled photocell, is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically isolated from each other. The light source is usually a light-emitting diode (LED), a miniature incandescent lamp, or sometimes a neon lamp, whereas the detector is a semiconductor-based photoresistor made of cadmium selenide (CdSe) or cadmium sulfide (CdS). The source and detector are coupled through a transparent glue or through the air. Electrically, RO is a resistance controlled by the current flowing through the light source. In the dark state, the resistance typically exceeds a few MOhm; when illuminated, it decreases as the inverse of the light intensity. In contrast to the photodiode and phototransistor, the photoresistor can operate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Logie Baird
John Logie Baird (; 13 August 188814 June 1946) was a Scottish inventor, electrical engineer, and innovator who demonstrated the world's first mechanical Mechanical television, television system on 26 January 1926. He went on to invent the first publicly demonstrated colour television system and the first viable purely electronic Color television, colour television picture tube. In 1928, the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history. In 2006, Baird was named as one of the 10 greatest Scottish scientists in history, having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. In 2015, he was inducted into the Scottish Engineering Hall of Fame. In 2017, IEEE unveiled a bronze street plaque at 22 Frith Street (Bar I ...

Nipkow Disk
A Nipkow disk (sometimes Anglicized as Nipkov disk; patented in 1884), also known as scanning disk, is a mechanical, rotating, geometrically operating image scanning device, patented by Paul Gottlieb Nipkow in Berlin. This scanning disk was a fundamental component in mechanical television, and thus the first televisions, through the 1920s and 1930s. Operation The device is a mechanically spinning disk of any suitable material (metal, plastic, cardboard, etc.), with a series of equally-distanced circular holes of equal diameter drilled in it. The holes may also be square for greater precision. These holes are positioned to form a single-turn spiral starting from an external radial point of the disk and proceeding to the center of the disk. When the disk rotates, the holes trace circular ring patterns, with inner and outer diameter depending on each hole's position on the disk and thickness equal to each hole's diameter. The patterns may or may not partially overlap, depending o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerr Effect
The Kerr effect, also called the quadratic electro-optic (QEO) effect, is a change in the refractive index of a material in response to an applied electric field. The Kerr effect is distinct from the Pockels effect in that the induced index change for the Kerr effect is directly proportional to the ''square'' of the electric field instead of varying linearly with it. All materials show a Kerr effect, but certain liquids display it more strongly than others. The Kerr effect was discovered in 1875 by Scottish physicist John Kerr. Two special cases of the Kerr effect are normally considered, these being the Kerr electro-optic effect, or DC Kerr effect, and the optical Kerr effect, or AC Kerr effect. Kerr electro-optic effect The Kerr electro-optic effect, or DC Kerr effect, is the special case in which a slowly varying external electric field is applied by, for instance, a voltage on electrodes across the sample material. Under this influence, the sample becomes birefringent, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melbourne Cup
The Melbourne Cup is an annual Group 1 Thoroughbred horse race held in Melbourne, Australia, at the Flemington Racecourse. It is a 3200-metre race for three-year-olds and older, conducted by the Victoria Racing Club that forms part of the Melbourne Spring Racing Carnival. It is the richest two-mile handicap in the world and one of the richest turf races. The event starts at 3:00 pm on the first Tuesday of November and is known locally as "the race that stops the nation". The Melbourne Cup has cemented itself as a part of Melbourne and Australian culture, having been run every year since 1861 (except for an intermission during World War I and World War II). The day of the race has been a public holiday for much of Victoria since 1876. It was originally run over but was shortened to in 1972 when Australia adopted the metric system. This reduced the distance by , and Rain Lover's 1968 race record of 3:19.1 was accordingly adjusted to 3:17.9. The present record holder is ...

Mechanical Television
Mechanical television or mechanical scan television is an obsolete television system that relies on a mechanism (engineering), mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode-ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) and LED displays are now used to create and display television pictures. Mechanical scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by Scottish inventor John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Argus (Melbourne)
''The Argus'' was an Australian daily morning newspaper in Melbourne from 2 June 1846 to 19 January 1957, and was considered to be the general Australian newspaper of record for this period. Widely known as a conservative newspaper for most of its history, it adopted a left-leaning approach from 1949. ''The Argus''s main competitor was David Syme's more liberal-minded newspaper, ''The Age ''The Age'' is a daily newspaper in Melbourne, Australia, that has been published since 1854.

The first edition was published on 2 June 1846. The paper soon became k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballarat East Fire Station
The Ballarat East Fire Station, in Ballarat East, Victoria, Australia is the oldest continually operating fire station in the Southern Hemisphere. The tower was designed by local architect Henry Caselli and was built in 1864 by William Cowland, a builder and fire brigade volunteer. Caselli's design for an Engine House was not built; an 1858-built structure was used. The Engine House was replaced by a new one in 1916. It was one site of the first operational telephone, made by Henry Sutton, which connected this station to the Ballarat Fire Station in Ballarat Ballarat ( ) () is a city in the Central Highlands of Victoria, Australia. At the 2021 census, Ballarat had a population of 111,973, making it the third-largest urban inland city in Australia and the third-largest city in Victoria.
