121 Renold, Hans
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 31 July 1852 Aarau, Switzerlandd. 2 May 1943 Grange-over-Sands, Lancashire, England[br]Swiss (naturalized British 1881) mechanical engineer, inventor and pioneer of the precision chain industry.[br]Hans Renold was educated at the cantonal school of his native town and at the Polytechnic in Zurich. He worked in two or three small workshops during the polytechnic vacations and served an apprenticeship of eighteen months in an engineering works at Neuchâtel, Switzerland. After a short period of military service he found employment as a draughtsman in an engineering firm at Saint-Denis, near Paris, from 1871 to 1873. In 1873 Renold moved first to London and then to Manchester as a draughtsman and inspector with a firm of machinery exporters. From 1877 to 1879 he was a partner in his own firm of machine exporters. In 1879 he purchased a small firm in Salford making chain for the textile industry. At about this time J.K.Starley introduced the "safety" bicycle, which, however, lacked a satisfactory drive chain. Renold met this need with the invention of the bush roller chain, which he patented in 1880. The new chain formed the basis of the precision chain industry: the business expanded and new premises were acquired in Brook Street, Manchester, in 1881. In the same year Renold became a naturalized British subject.Continued expansion of the business necessitated the opening of a new factory in Brook Street in 1889. The factory was extended in 1895, but by 1906 more accommodation was needed and a site of 11 ½ acres was acquired in the Manchester suburb of Burnage: the move to the new building was finally completed in 1914. Over the years, further developments in the techniques of chain manufacture were made, including the invention in 1895 of the inverted tooth or silent chain. Renold made his first visit to America in 1891 to study machine-tool developments and designed for his own works special machine tools, including centreless grinding machines for dealing with wire rods up to 10 ft (3 m) in length.The business was established as a private limited company in 1903 and merged with the Coventry Chain Company Ltd in 1930. Good industrial relations were always of concern to Renold and he established a 48-hour week as early as 1896, in which year a works canteen was opened. Joint consultation with shop stewards date2 from 1917. Renold was elected a Member of the Institution of Mechanical Engineers in 1902 and in 1917 he was made a magistrate of the City of Manchester.[br]Principal Honours and DistinctionsHonorary DSc University of Manchester 1940.Further ReadingBasil H.Tripp, 1956, Renold Chains: A History of the Company and the Rise of the Precision Chain Industry 1879–1955, London.J.J.Guest, 1915, Grinding Machinery, London, pp. 289, 380 (describes grinding machines developed by Renold).RTS -
122 Tesla, Nikola
SUBJECT AREA: Electricity[br]b. 9 July 1856 Smiljan, Croatiad. 7 January 1943 New York, USA[br]Serbian (naturalized American) engineer and inventor of polyphase electrical power systems.[br]While at the technical institute in Graz, Austria, Tesla's attention was drawn to the desirability of constructing a motor without a commutator. He considered the sparking between the commutator and brushes of the Gramme machine when run as a motor a serious defect. In 1881 he went to Budapest to work on the telegraph system and while there conceived the principle of the rotating magnetic field, upon which all polyphase induction motors are based. In 1882 Tesla moved to Paris and joined the Continental Edison Company. After building a prototype of his motor he emigrated to the United States in 1884, becoming an American citizen in 1889. He left Edison and founded an independent concern, the Tesla Electric Company, to develop his inventions.The importance of Tesla's first patents, granted in 1888 for alternating-current machines, cannot be over-emphasized. They covered a complete polyphase system including an alternator and induction motor. Other patents included the polyphase transformer, synchronous motor and the star connection of three-phase machines. These were to become the basis of the whole of the modern electric power industry. The Westinghouse company purchased the patents and marketed Tesla motors, obtaining in 1893 the contract for the Niagara Falls two-phase alternators driven by 5,000 hp (3,700 kW) water turbines.After a short period with Westinghouse, Tesla resigned to continue his research into high-frequency and high-voltage phenomena using the Tesla coil, an air-cored transformer. He lectured in America and Europe on his high-frequency devices, enjoying a considerable international reputation. The name "tesla" has been given to the SI unit of magnetic-flux density. The induction motor became one of the greatest advances in the industrial application of electricity. A claim for priority of invention of the induction motor was made by protagonists of Galileo Ferraris (1847–1897), whose discovery of rotating magnetic fields produced by alternating currents was made independently of Tesla's. Ferraris demonstrated the phenomenon but neglected its exploitation to produce a practical motor. Tesla himself failed to reap more than a small return on his work and later became more interested in scientific achievement than commercial success, with his patents being infringed on a wide scale.[br]Principal Honours and DistinctionsAmerican Institute of Electrical Engineers Edison Medal 1917. Tesla received doctorates from fourteen universities.Bibliography1 May 1888, American patent no. 381,968 (initial patent for the three-phase induction motor).1956, Nikola Tesla, 1856–1943, Lectures, Patents, Articles, ed.

pollution effect
The main pollution effects concern human health and cover all aspects of the physical environment - air, water and land, including the effects of climate change. Human activities which are sources of pollution arise from domestic, commercial, industrial and military sectors and their effects are influenced by various issues, trends and public sector programmes, such as safe water and food, management of waste, increasing use of chemicals in agriculture, and urbanization. Types of pollutants which are negatively impacting health include litter, toxic chemicals, nuclear waste, lead, spoil from mining, food and water contaminants; and the polluting effects of over-population.
