Granted: 1990-05-21
Abstract: The safety device for an oil burner comprises a flame electrode arranged at a position to be exposed to flame formed due to normal combustion in the oil burner. An AC voltage is applied between the flame electrode and the oil burner so that normal combustion in the oil burner may be detected when a DC flame current flows through the flame electrode due to the rectification of flame carried out between the flame electrode and the oil burner. Another flame electrode is arranged at a position to which flame of the normal combustion in the oil burner does not reach. An AC voltage is applied using a circuit providing a single source of current to the eletrodes and dividing current from the single source between the flame electrodes when the second electrode is reached by an excessive flame.

Abstract: 본 발명은 제지 공정과 유사한 공정에 의해, 미세하게 피브릴화된 셀룰로오즈를 웹으로 형성시킴으로써 수득한 음향 진동판에 관한 것이다. 미세하게 피브릴화된 셀룰로오즈는 캐나다 표준 자유도가 300ml 이하로 될 때까지 빗팅시킴으로써 수득한 셀룰로오즈 또는 박테리아성 셀룰로오즈이다. 미세하게 피브릴화된 셀룰로오즈의 습윤 강도는 매우 열악하기 때문에, 보강재로 보강시키며, 보강시킨 상태하에 와이어 스크린상에서 웹으로 형성시킨다. 보강재는, 웹을 형성시킨 후에 떼어내거나, 또는 셀룰로오즈 웹에 적층된 상태로 두어 생성된 복합 생성물을 음향 진동판으로서 사용할 수 있다.
