Chord (music)
A chord, in music, is any harmonic set of pitches/frequencies consisting of multiple notes (also called "pitches") that are heard as if sounding simultaneously. For many practical and theoretical purposes, arpeggios and broken chords (in which the notes of the chord are sounded one after the other, rather than simultaneously), or sequences of chord tones, may also be considered as chords in the right musical context. In tonal Western classical music (music with a tonic key or "home key"), the most frequently encountered chords are triads, so called because they consist of three distinct notes: the root note, and intervals of a third and a fifth above the root note. Chords with more than three notes include added tone chords, extended chords and tone clusters, which are used in contemporary classical music, jazz and almost any other genre. A series of chords is called a chord progression. One example of a widely used chord progression in Western traditional music and blu ...

HMS Patroller (D07)
HMS ''Patroller'' was an escort carrier in the Royal Navy during the Second World War. Laid down in 1942 at the Seattle-Tacoma Shipbuilding company, she was originally named USS ''Keweenaw'' (CVE-44). USS ''Keweenaw'' (previously AVG-44 then later ACV-44) was an escort carrier laid down under Maritime Commission contract by Seattle-Tacoma Shipbuilding of Tacoma, Washington, 27 November 1942; launched 6 May 1943; sponsored by Mrs. R. G. Risley; assigned to the United Kingdom 10 June 1943; reclassified CVE-44 on 15 July 1943; and transferred to the United Kingdom under lend-lease 22 October 1943. During the remainder of war, she served the Royal Navy as HMS ''Patroller'' and operated in the Atlantic on convoy escort and patrol duty, with brief stints as a transport carrier for both the Army and Navy. Arriving Norfolk, Virginia, 9 December 1946, she was returned to the United States Navy the same day. Her name was struck from the Naval Vessel Registry 7 February 1947 and she was ...

D7 Polytope
In 7-dimensional geometry, there are 95 uniform 7-polytope, uniform polytopes with D7 symmetry; 32 are unique, and 63 are shared with the B7 symmetry. There are two regular forms, the 7-orthoplex, and 7-demicube with 14 and 64 vertices respectively. They can be visualized as symmetric orthographic projections in Coxeter planes of the D6 Coxeter group, and other subgroups. __TOC__ Graphs Symmetric orthographic projections of these 32 polytopes can be made in the D7, D6, D5, D4, D3, A5, A3, Coxeter planes. Ak has ''[k+1]'' symmetry, Dk has ''[2(k-1)]'' symmetry. B7 is also included although only half of its [14] symmetry exists in these polytopes. These 32 polytopes are each shown in these 8 symmetry planes, with vertices and edges drawn, and vertices colored by the number of overlapping vertices in each projective position.

BSA Bantam
The BSA Bantam is a two-stroke unit construction motorcycle that was produced by the Birmingham Small Arms Company (BSA) from 1948 (as a 125 cc) until 1971 (as a 175 cc). Exact production figures are unknown, but it was over 250,000 and some estimates place the number closer to half a million. History Despite the Bantam being considered the archetypal 'truly British' lightweight motorcycle outselling all others, it was based on a German design. The Bantam was based on the DKW RT 125, a design that was received as war reparations, with the Bantam as a mirror image so the gearchange was on the right side as with other British motorcycles of the period. The same design went into production in at least two, and perhaps four, other countries. Harley-Davidson started producing their Model 125 in late 1947 (several months before BSA) and the occupiers of East Germany, the U.S.S.R. began building the Москва (Moskva) M1A model even earlier, c.1946. In East Germany the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATS D7
The ATS D7 was a Formula One racing car used by Team ATS in the 1984 Formula One season. The car was designed by Gustav Brunner and was driven for most of the season by German Manfred Winkelhock. He was joined in a second car late in the season by Formula One rookie, Austrian driver Gerhard Berger. It was the last car produced by the ATS team. Racing history Early in the season, the D7 with its powerful turbocharged BMW engine, showed surprising speed, if not reliability. Winkelhock qualified sixth at Zolder for the Belgian Grand Prix and early in the race ran confidently in fourth place behind the Ferraris of Michele Alboreto and René Arnoux and the Renault of Derek Warwick before exhaust failure put him out on lap 39. He then qualified seventh for the next race in San Marino and again was racing in the points (top six) before his race ended in turbo failure. Winkelhock only managed to finish two races in the quick but unreliable D7, finishing eighth in both Canada and Dallas. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Railroad Class D7
Class D7 (formerly Class A (anthracite), pre-1895) on the Pennsylvania Railroad was a class of 4-4-0 steam locomotive. Fifty-eight were built by the PRR's Altoona Works (now owned by Norfolk Southern) between 1882–1891 with drivers, while sixty-one of class D7a were constructed with drivers.

Dewoitine D
Constructions Aéronautiques Émile Dewoitine was a French aircraft manufacturer established by Émile Dewoitine at Toulouse in October 1920. The company's initial products were a range of metal parasol-wing fighters which were largely ignored by the French Air Force but purchased in large quantities abroad and licence-built in Italy, Switzerland, and Czechoslovakia. The company was liquidated in January 1927, with the only remaining active programme (the D.27) being transferred to EKW in Switzerland. The company was re-established in Paris in March the following year as Société Aéronautique Française (Avions Dewoitine) or SAF. After briefly continuing D.27 production, the reconstituted firm produced a range of fighters that became a mainstay of the French airforce during the 1930s, the D.500 family. It also developed important civilian airliners, such as the D.333 and its derivative the D.338, designed for pioneering routes to French Indochina (Vietnam), and eventually Hon ...

Caterpillar D7
The Caterpillar D7 is a medium track-type tractor manufactured by Caterpillar Inc. and most commonly used as a bulldozer. The D7 was first manufactured in 1938. A series of improved models were later produced, including the D7C in 1955, the D7D in 1959, the D7E in 1961, the D7F in 1969 and the D7G in 1974. In 1986 the D7H was the first D7 equipped with Caterpillar’s elevated drive sprocket undercarriage. The D7R replaced the D7H in 1996, followed by the D7R Series 2. The electric drive D7E entered service in early 2009, returning to a traditional ‘flat-track’ configuration for this iteration only. The high-drive design returned in 2020 with the introduction of the D7 (forgoing a generational letter under Caterpillar’s new naming system). In March 2008, at Conexpo 2008 held every 3 years in Las Vegas, Caterpillar introduced the D7E. This D7E comes with a diesel-electric drive system powered by a 537cid C9.3 diesel engine. The C9.3 powers a generator that turns o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavarian D VII
The locomotives of the Bavarian Class D VII were saturated steam locomotives of the Royal Bavarian State Railways (''Königlich Bayerische Staatsbahn''). The D VII was built, in parallel with the D VI, as a six-coupled locomotive for hilly routes. A total of 75 examples were made, 41 by Krauss and 34 by Maffei. From 1885 the locomotives were somewhat longer, and had more water and coal capacity, so were also heavier. The Deutsche Reichsbahn-Gesellschaft took over all 75 locomotives in 1925 as DRG Class 98.76 (''Baureihe 98.76''). Most were retired by the end of the 1920s, the last one however not until 1935. One example, D VII no. 1854 – later 98 7658, is in the branch line museum at Bayerisch Eisenstein owned by the Bavarian Localbahn Society.

HMS D7
HMS ''D7'' was one of eight D-class submarines built for the Royal Navy during the first decade of the 20th century. Description The D-class submarines were designed as improved and enlarged versions of the preceding C class, with diesel engines replacing the dangerous petrol engines used earlier. ''D3'' and subsequent boats were slightly larger than the earlier boats. They had a length of overall, a beam of and a mean draught of . They displaced on the surface and submerged.Harrison, Chapter 4 The D-class submarines had a crew of 25 officers and ratings and were the first to adopt saddle tanks.Gardiner & Gray, p. 87 For surface running, the boats were powered by two diesels, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the D class had a range of at . The boats were armed with three 18-inch (45 cm) torpedo tubes, two in the bow and one in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker D
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.
