6 региональная компания телефонной связи
региональная компания телефонной связи
Крупная американская компания, владеющая несколькими местными телефонными компаниями (см. LEC) в конкретном географическом регионе. В 1984 г. после отделения от AT&T было образовано семь компаний RBOC: Ameritech, Bell Atlantic, BellSouth, Nynex, Pacific Telesis Group, SBC Communications и U.S.West. Однако затем в результате слияния SBC Communications с Pacific Telesis Group и Nynex с Bell Atlantic их число сократилось до пяти.

16 Gray, Elisha
SUBJECT AREA: Telecommunications[br]b. 2 August 1835 Barnesville, Ohio, USAd. 21 January 1901 Newtonville, Massachusetts, USA[br]American inventor who was only just beaten by Alexander Graham Bell in the race for the first telephone patent.[br]Initially apprenticed to a carpenter, Gray soon showed an interest in chemistry, but he eventually studied electrical engineering at Oberlin College, Oberlin, Ohio, in the late 1850s. In 1869 he founded the Western Electric Manufacturing Company, where he devised an electric-needle annunciator for use in hotels and lifts and carried out experimental work aimed at the development of a means of distant-speech communication. After successful realization of a liquid-based microphone and public demonstrations of a receiver using a metal diaphragm, on 14 February 1876 he deposited a caveat of intention to file a patent claim within three months for the invention of the telephone, only to learn that Alexander Graham Bell had filed a full patent claim only three hours earlier on the same day. Following litigation, the patent was eventually awarded to Bell. In 1880 Gray was appointed Professor of Dynamic Electricity at Oberlin College, but he appears to have retained his business interests since in 1891 he was both a member of the firm of Gray and Barton and electrician to his old firm, Western Electric. Subsequently, in 1895, he invented the TelAutograph, a form of remote-writing telegraph, or facsimile, capable of operating over short distances. The system used a transmitter in which the x and y movements of a writing stylus were coupled to a pair of variable resistors. In turn, these were connected by two telegraph wires to a pair of receiving coils, which were used to control the position of a pen on a sheet of paper, thus replicating the movement of the original stylus.[br]Bibliography1878, Experimental Research in Electro-Harmonic Telegraph and Telephony, 1867–76.Further ReadingJ.Munro, 1891, Heroes of the Telegraph.D.A.Hounshill, 1975, "Elisha Gray and the telephone.

17 Howden, James
SUBJECT AREA: Steam and internal combustion engines[br]b. 29 February 1832 Prestonpans, East Lothian, Scotlandd. 21 November 1913 Glasgow, Scotland[br]Scottish engineer and boilermaker, inventor of the forced-draught system for the boiler combustion chamber.[br]Howden was educated in Prestonpans. While aged only 14 or 15, he travelled across Scotland by canal to Glasgow, where he served an engineering apprenticeship with James Gray \& Co. In 1853 he completed his time and for some months served with the civil engineers Bell and Miller, and then with Robert Griffiths, a designer of screw propellers for ships. In 1854, at the age of 22, Howden set up as a consulting engineer and designer. He designed a rivet-making machine from which he realized a fair sum by the sale of patent rights, this assisting him in converting the design business into a manufacturing one. His first contract for a marine engine came in 1859 for the compound steam engine and the watertube boilers of the Anchor Liner Ailsa Craig. This ship operated at 100 psi (approximately 7 kg/cm2), well above the norm for those days. James Howden \& Co. was formed in 1862. Despite operating in the world's most competitive market, the new company remained prosperous through the flow of inventions in marine propulsion. Shipbuilding was added to the company's list of services, but such work was subcontracted. Work was obtained from all the great shipping companies building in the Glasgow region, and with such throughput Howden's could afford research and experimentation. This led to the Howden hot-air forced-draught system, whereby furnace waste gases were used to heat the air being drawn into the combustion chambers. The first installation was on the New York City, built in 1885 for West Indian service. Howden's fertile mind brought about a fully enclosed high-speed marine steam engine in the 1900s and, shortly after, the Howden-Zoelly impulse steam turbine for land operation. Until his death, Howden worked on many technical and business problems: he was involved in the St Helena Whaling Company, marble quarrying in Greece and in the design of a recoilless gun for the Admiralty.[br]Principal Honours and DistinctionsHowden was the last surviving member of the group who founded the Institution of Engineers and Shipbuilders in Scotland in 1857.BibliographyHowden contributed several papers to the Institution of Engineers and Shipbuilders in Scotland.Further ReadingC.W.Munn, 1986, "James Howden", Dictionary of Scottish Business Biography, Vol. I, Aberdeen.FMW
