Firedamp whistle : ウィキペディア英語版 | Firedamp whistle
A firedamp whistle (German: ''Schlagwetterpfeife'') is an instrument for the prophylactic indication of firedamp — flammable gases often present in coal mines. == History ==
The German Emperor Wilhelm II asked Fritz Haber in 1912, shortly after the opening of the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin, for the construction of a warning system for the presence of firedamp.〔(Dirk Van Laak: Deutscher als der Kaiser )〕 Within a year Haber developed the methane whistle and presented it to the emperor in a lecture on October 28, 1913. Haber tried hard to market the device and eventually signed a contract with the Auergesellschaft. Unfortunately, the device did not prevail, since the calibration of the pipes under working conditions in a colliery was not practical.〔Margit Szöllösi-Janze: ''Fritz Haber 1868-1934: Eine Biographie'', Verlag C. H.Beck, 1998, ISBN 978-3406435485, p. 240-242〕
