Torx
Torx (pronounced ) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967, Bernard F. Reiland, "Coupling arrangement and tools for same", filed 1967-03-21 by Camcar Textron. A popular generic name for the drive is ''star'', as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral ''6'', not the capital letter ''G''). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles. Star screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-r ...

Fluorescent Lamp Formats
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors ( fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray d ...

TORRO Scale
The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO), a meteorological organisation in the United Kingdom, as an extension of the Beaufort scale. History and derivation from Beaufort scale The scale was tested from 1972 to 1975 and was made public at a meeting of the Royal Meteorological Society in 1975. The scale sets T0 as the equivalent of 8 on the Beaufort scale and is related to the Beaufort scale (B), up to 12 on the Beaufort scale, by the formula: : ''B'' = 2 (''T'' + 4) and conversely: : ''T'' = (''B''/2 - 4) The Beaufort scale was first introduced in 1805, and in 1921 quantified. It expresses the wind speed as faster than v in the formula: : v = 0.837 ''B''3/2 m/s TORRO scale formula Most UK tornadoes are T6 or below with the strongest known UK tornado estimated as a T8 (the London tornado of 1091).

Thoracic Vertebrae
In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being much larger than the upper. They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs, as well as facets on the transverse processes of all, except the eleventh and twelfth, for articulation with the tubercles of the ribs. By convention, the human thoracic vertebrae are numbered T1–T12, with the first one (T1) located closest to the skull and the others going down the spine toward the lumbar region. General characteristics These are the general characteristics of the second through eighth thoracic vertebrae. The first and ninth through twelfth vertebrae contain certa ...

Spinal Nerve
A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. The spinal nerves are part of the peripheral nervous system. Structure Each spinal nerve is a mixed nerve, formed from the combination of nerve fibers from its dorsal and ventral roots. The dorsal root is the afferent sensory root and carries sensory information to the brain. The ventral root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening ( intervertebral foramen) between adjacent vert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trikke
The Trikke works by shifting body weight The Trikke ( ; also known as a wiggle scooter, scissor scooter, carver scooter, and Y scooter) is a chainless, pedalless, personal vehicle with a three-wheel frame. The rider stands on two foot platforms above the two rear wheels and steers the vehicle with handlebars attached to the lone front wheel. The cambering system is designed to provide a stable, three-point platform that lets the rider lean into turns while all three wheels remain in contact with the ground. There are several variations of the Trikke, from body-powered fitness machines, to battery-powered transportation and personal mobility vehicles. Brand name Trikkes are manufactured by the company Trikke Tech based in Buellton, California Buellton is a small city in Santa Barbara County, California, United States. It is located in the Santa Ynez Valley, west of Solvang. The population was 5,161 at the 2020 census, up from 4,828 at the 2010 census. Located at the juncti ...

OS T1000
T1000 and T1300 were two rapid transit train classes used on Oslo Metro in Oslo, Norway. The 197 cars were built by Strømmens Verksted, Norsk Elektrisk & Brown Boveri and AEG between 1960 and 1981. They were the first metro trains used in Oslo, and had remained in active use until being replaced by OS MX3000 trains in 2007. Each car was equipped with a driver's cab at one or both ends and four motors, each with . The cars were long, wide and tall. The trains used 750 V current, and were capable of . Signaling was provided through automatic train protection. In 1960, two less powerful T single-car units were built, designed to be prototypes used on the Oslo Tramway. After a one-year trial, they were put into scheduled traffic to the Kolsås Line, where they remained in regular service until 1983. The production series was somewhat different in design and performance. T1000 was both used to refer to the class as a whole, or the first 162 cars, that are only equipped wit ...

Airport & South Line
The Airport & South Line (numbered T8, coloured green) (''commonly called the East Hills Line)'' is a suburban commuter rail line in Sydney, Australia. It connects the Sydney central business district with the southwestern suburbs via Sydney Airport. The line is part of the Sydney Trains network. The line began operating on 26 November 2017, when the T2 Airport, Inner West & South Line was split in two. Sydney Trains' predecessor CityRail operated the Airport & East Hills line over an identical route between 2000 and 2013. History The T8 traverses several railway lines; the City Circle, Airport Link, East Hills and Main South lines. The origins of the current train service can be traced back to the opening of the East Hills line in 1931. The East Hills line was extended to Glenfield in 1987, where it joins the Main South line. The Airport line opened in 2000, providing an additional pair of tracks into the city. The East Hills line was opened in 1931. Electrification onl ...

Hong Kong Tropical Cyclone Warning Signals
The Hong Kong tropical cyclone warning signals, or informally typhoon signals, are a set of signals used to indicate the threat or effects of a tropical cyclone. The Hong Kong Observatory issues the warning signal if a tropical cyclone approaches within of Hong Kong and poses a threat of deteriorating conditions in Hong Kong. The signals are represented as a set of numbers and symbols. Previously lights were also used at night. Signal System Beginning Local people in Hong Kong were warned of the hazardous wind conditions associated with tropical cyclones by means of a typhoon gun as early as August 1884. At the time, the typhoon gun was placed at the foot of the mast in front of the Police Barracks at Tsim Sha Tsui facing Victoria Harbour. It was fired once whenever a strong gale of wind was expected. It was fired twice whenever the wind was expected to blow with typhoon force and fired again if possible when the wind was likely to suddenly shift around. The first typhoon gun ...
