His patent kick-started Sheffield's steel industry, but the poor wording of his patent caused competitors not to pay him royalties,〔 and he died in poverty. == Career in India == At the start of the 19th century, metallurgy in British India was very traditional, localised and artisanal. Around 1825, Heath (who wanted to continue the important progress of European methods), obtained from the British East India Company the monopoly of iron production over a large area centred on Madras. In 1830, factories were built at Porto Novo, in the south of the Arcot district, with a government loan. In 1833, the company was named the "Porto Novo Steel and Iron Company", the workshops were enlarged and a new factory was built at Beypore in the Malabar region. The steel was of very good quality, and was even exported to Great Britain where it was used, notably, in the construction of the Menai Suspension Bridge and the Britannia Bridge, across the Menai Straits between mainland Wales and Anglesey ((ウェールズ語:Ynys Môn)). But the business ran at a loss, because of management failings, technical inexperience, lack of funding and the sole use of charcoal as a combustion agent. (A buyer had previously suggested to Heath that he move his factory to the Burdwan district of Bengal, where coal was abundant, but he did not act on the suggestion.) The business was taken over by the East India Company in 1853, who continued running it as a going concern until 1874, when it was placed into liquidation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Josiah Marshall Heath」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
