Whitby Lighthouse
Whitby Lighthouse is a lighthouse operated by Trinity House. It is on Ling Hill, on the coast to the south-east of Whitby, beyond Saltwick Bay. To distinguish it from the two lighthouses in Whitby itself (which protect the town's harbour) it is sometimes known as Whitby High lighthouse (and is referred to as such on Admiralty charts) History The lighthouse, a white octagonal brick tower, was designed by James Walker of civil engineers Messrs. Walker, Burgess & Cooper. Foundations were laid on 12 April 1857 with construction carried out by local builder William Falkingbridge of Well Close Square, Whitby. Supervising the construction Henry Norris of James Walker's firm was engaged as ''Superintendent of the Works'' on behalf of Trinity House. The light, a 1st Order assembly manufactured by Chance Brothers of Smethwick, was first lit on 1 October 1858 with costs of construction having run to about £8,000. Originally, it was one of a pair of towers aligned north-south and kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitby
Whitby is a seaside town, port and civil parish in the Scarborough borough of North Yorkshire, England. Situated on the east coast of Yorkshire at the mouth of the River Esk, Whitby has a maritime, mineral and tourist heritage. Its East Cliff is home to the ruins of Whitby Abbey, where Cædmon, the earliest recognised English poet, lived. The fishing port emerged during the Middle Ages, supporting important herring and whaling fleets, and was where Captain Cook learned seamanship and, coincidentally, where his vessel to explore the southern ocean, ''The Endeavour'' was built.Hough 1994, p. 55 Tourism started in Whitby during the Georgian period and developed with the arrival of the railway in 1839. Its attraction as a tourist destination is enhanced by the proximity of the high ground of the North York Moors national park and the heritage coastline and by association with the horror novel '' Dracula''. Jet and alum were mined locally, and Whitby jet, which was mined b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withernsea Lighthouse
Withernsea Lighthouse is an inland lighthouse that stands in the middle of the town of Withernsea in the East Riding of Yorkshire, England. The lighthouse stands 127 feet (38 m) high and took 18 months to build between 1892 and 1894. Formerly owned and run by Trinity House of London, it ceased operation on 1 July 1976 and is now used as a museum. History The lighthouse is a surprising distance (nearly ) from the sea front. At the time it was built, there was nothing between it and the sea but sand dunes, and fear of coastal erosion led to it being positioned well back. The lantern atop the tower and the Fresnel lens optic within it both came 'second-hand' from the old North Lighthouse at High Whitby, which had been decommissioned shortly before the building work at Withernsea began. Initially, the light was provided by an eight-wick paraffin lamp, which was set within the fixed first-order catadioptric optic (which had been designed and manufactured by Chance Brothe ...

Lighthouses In North Yorkshire
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mantle Lamp
A Coleman white gas lantern mantle glowing at full brightness An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. ''Mantle'' refers to the way it hangs like a cloak above the flame. Gas mantles were also used in portable camping lanterns, pressure lanterns and some oil lamps. Gas mantles are usually sold as fabric items, which, because of impregnation with metal nitrates, burns away to leave a rigid but fragile mesh of metal oxides when heated during initial use; these metal oxides produce light from the heat of the flame whenever used. Thorium dioxide was commonly a major component; being radioactive, it has led to concerns about the safety of those involved in manufacturing mantles. Normal use, however, poses minimal health risk.

Horn (acoustic)
An acoustic horn or waveguide is a tapered sound guide designed to provide an acoustic impedance match between a sound source and free air. This has the effect of maximizing the efficiency with which sound waves from the particular source are transferred to the air. Conversely, a horn can be used at the receiving end to optimize the transfer of sound from the air to a receiver. Acoustic horns are found in nature in the form of the burrows constructed by male mole crickets to amplify their song. The earliest appearance of the horn in connection to sound in The Times was published in 1786: Applications Acoustic horns are used in: * horn loudspeakers * brass and woodwind musical instruments * vehicle horns such as those used on cars, trucks, trains, boats, and bicycles * megaphones, often used by lifeguards at public swimming pools. * foghorns, used to warn ships * ear horns, used by people who are hard of hearing (the human ear itself having the form of a horn) * pickup horns ...

Hawsker
Hawsker is the name for the combined villages of High and Low Hawsker that straddle the A171 road south east of Whitby, in North Yorkshire, England. History The name Hawsker derives from Old Norse and means Haukr's enclosure. The settlement was listed in the Domesday Book as belonging to Earl Hugh in ''Nortreding''. Hawsker was originally in the parish of Whitby, but in 1878 it was split off into its own parish (Hawsker-cum-Stainsacre) along with neighbouring hamlet of Stainsacre where the parish church of All Saints is located. the population of the parish is 790 and includes the hamlet of Stainsacre and the wider parish which amounts to over in area. The two settlements of High and Low Hawsker are divided by the A171 road between Whitby and Scarborough; Low Hawsker lies to the west of the road and High Hawsker lies to the east. Low Hawsker used to have a working windmill; this was built in 1861 by George Burnett and was known to be in use up until 1915. The upper storeys ...

Lord Rayleigh
John William Strutt, 3rd Baron Rayleigh, (; 12 November 1842 – 30 June 1919) was an English mathematician and physicist who made extensive contributions to science. He spent all of his academic career at the University of Cambridge. Among many honors, he received the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies." He served as president of the Royal Society from 1905 to 1908 and as chancellor of the University of Cambridge from 1908 to 1919. Rayleigh provided the first theoretical treatment of the elastic scattering of light by particles much smaller than the light's wavelength, a phenomenon now known as "Rayleigh scattering", which notably explains why the sky is blue. He studied and described transverse surface waves in solids, now known as "Rayleigh waves". He contributed extensively to fluid dynamics, with concepts such as the Rayleigh number (a d ...

Siren (alarm)
A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire engines. There are two general types: mechanical and electronic. Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire sirens are either mounted on the roof of a fire station or on a pole next to the fire station. Fire sirens can also be mounted on or near government buildings, on tall structures such as water towers, as well as in systems where several sirens are distributed around a town for better sound coverage. Most fire sirens are single tone and mechanically driven by electric motors with a rotor attached to the shaft. Some newer sirens are electronically driven speakers. Fire sirens are often called "fire whistles", "fire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
