Safety fuse was a great advance in mining technology over the practice of filling holes with black powder. The next step in mining technology was detonating cord. Ensign-Bickford and other companies developed different versions of detonating cord. Ensign-Bickford's "Primacord" or "primercord"〔http://www.britannica.com/EBchecked/topic/476049/Primacord〕 became the functional generic name for detonating cord in North America. In May, 2003 Ensign-Bickford sold the trademarks and processes to Dyno Nobel Inc〔http://www.dynonobel.com/about-dyno-nobel/history/〕 of Australia (formerly of Norway). ==References== 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「Ensign-Bickford Company」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.
