885 Deaths
Year 885 ( DCCCLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. Events By place Europe * Summer – Emperor Charles the Fat summons a meeting of officials at Lobith (modern Netherlands), and accuses Hugh, an illegitimate son of former king Lothair II, and his vassal Godfrid, Duke of Frisia, of plotting against him. Hugh is blinded, and exiled to the Abbey of Saint Gall (modern Switzerland). Godfrid is killed by a group of Frisian and Saxon nobles, at the connivance of Henry of Franconia. The local count, Gerolf, takes over the West Frisian coastline from the Danish, after the murder. * Summer – Charles the Fat designates his illegitimate son Bernard as his heir, ignoring the claims of his nephew, Arnulf of Carinthia (illegitimate son of Carloman of Bavaria), and Charles the Simple (5-year-old son of King Louis the Stammerer). The Frankish bishops protest, so Charles summons Pope Adrian III to an asse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyratron
A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Thyratrons can handle much greater currents than similar hard-vacuum tubes. Electron multiplication occurs when the gas becomes ionized, producing a phenomenon known as Townsend discharge. Gases used include mercury vapor, xenon, neon, and (in special high-voltage applications or applications requiring very short switching times) hydrogen. Unlike a vacuum tube (valve), a thyratron cannot be used to amplify signals linearly. In the 1920s, thyratrons were derived from early vacuum tubes such as the UV-200, which contained a small amount of argon gas to increase its sensitivity as a radio signal detector, and the German LRS relay tube, which also contained argon gas. Gas rectifiers, which predated vacuum tubes, such as the argon-filled General Electric " Tungar bulb" and the Cooper-Hewitt mercury-pool rectifier, also provided an influence. Irving Langmuir and G. S. Meikle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Of Franconia
Henry (died 28 August 886) was the leading military commander of the last years of the Carolingian Empire. He was commander-in-chief under Kings Louis the Younger and Charles the Fat. His early career was mostly restricted to East Francia, his homeland, but after Charles inherited West Francia in 884 he was increasingly active there. During his time, raids by the Vikings (mainly Danes) peaked in Francia. The sources describe at least eight separate campaigns waged by Henry against the Vikings, most of them successful. Henry is described in the sources as a Saxon, Frank or Thuringian. His title is given variously as count (Latin ''comes''), margrave (''marchensis'') or duke (''dux''). The territory he governed is described variously in the sources as Francia, Neustria or Austrasia, perhaps indicating that his military command covered most of the north of the empire from the Breton March in the west to Frisia and Saxony in the east. Family Henry's family has been called the Popp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
