Apparatus for spectral analysis of molten substances
Abstract
Abstract APPARATUS FOR DIRECT SPECTROMETRIC EXAMINATION OF MOLTEN METALS OR THE LIKE HAS A CRUCIBLE WHICH IS TO BE PARTIALLY FILLED WITH MOLTEN MATERIAL AND JACKET DEFINING WITH THE CRUCIBLE A COMPARTMENT WHICH SURROUNDS THE CRUCIBLE. THE JACKET HAS A CLOSURE FOR THE UPPER ENDS OF THE COMPARTMENT AND OF A CHAMBER IN THE CRUCIBLE ABOVE THE EXPOSED SURFACE OF MOLTEN MATERIAL. A COMPRESSED NEUTRAL GAS IS CIRCULATED THROUGH THE CHAMBER AND THEREUPON THROUGH THE COMPARTMENT, AND THE CLOSURE IS TRAVERSED BY TWO ELECTRODES ONE OF WHICH DIPS INTO MOTLETN MATERIAL. THE ELECTRODES ARE CONNECTED TO THE POLES OF A GENERATOR WHICH PRODUCES SPARKS BETWEEN THE EXPOSED SURFACE OF MOLTEN MATERIAL AND THE TIP OF THE OTHER ELECTRODE. THE THUS PRODUCED LIGHT IS DIRECTED FOR THE PURPOSES OF ANALYSIS INTO A SPECTROMETER BY WAY OF A DUCT WHICH EXTENDS FROM AN OPENING IN THE CRUCIBLE AND ADMITS SOME COMPRESSED GAS INTO THE CHAMBER ABOVE THE EXPOSED SURFACE OF MOLTEN MATERIAL. THE REMAINING GAS IS ADMITTED THROUGH THE HOLDER FOR THE OTHER ELECTRODE WHICH IS ADJUSTABLE TOWARD AND AWAY FROM THE EXPOSED SURFACE OF MOLTEN MATERIAL.
