Abstract: AN ELECTRODE ASSEMBLY FOR USE IN AN ELECTROLYTIC CELL HAVING A CORROSIVE ENVIRONMENT COMPRISING HIGH TEMPERATURE CHLORINE GAS AND A BATH OF ALUMINUM CHLORIDE DISSOLVED IN ONE OR MORE SALTS. THE ASSEMBLY COMPRISES AN ELECTRODE DISPOSED WITHIN THE CELL, AT LEAST ONE ELECTRICAL CURRENT CONDUCTING LEAD MADE OF MATERIAL SUSCEPTIBLE TO CORROSIVE ATTACK BY THE ENVIRONMENT EXTENDING INTO THE ELECTRODE, AND A FLUID IMPREVIOUS, ELECTRICALLY CONDUCTIVE SLEEVE DISPOSED AROUND THE LEAD ALONG AT LEAST THE LENGTH THEREOF EXTENDING THROUGH A WALL OF THE CELL, AND IN CONTACT WITH THE ELECTRODE. THE FLUID IMPERVIOUS SLEEVE IS EFFECTIVE TO PREVENT CONTACT OF APPROACHING CORROSIVE CONSTITUENTS WITH THE LEAD.

Abstract: A process for producing aluminum, including electrolytically decomposing alumina to aluminum metal in an electrolyte bath between a carbon anode and a cathodic interface formed between metal and the electrolyte bath, the bath A. CONSISTING ESSENTIALLY OF Al2O3, NaF, and A1F3, and B. HAVING A WEIGHT RATIO NaF to A1F3 up to 1.1:1, WHILE MAINTAINING THE BATH AT AN OPERATING TEMPERATURE EFFECTIVE FOR PREVENTING BATH CRUSTING IN INTERFACIAL AREAS BETWEEN BATH AND ALUMINUM METAL, WHILE ENCLOSING THE TOP OF THE CELL FOR KEEPING THE SURFACE OF THE BATH MOLTEN, AND WHILE FEEDING ALUMINA A. SUBSTANTIALLY CONTINUOUSLY ONTO THE MOLTEN BATH SURFACE, B. THE ALUMINA HAVING A WATER CONTENT EFFECTIVE FOR PREVENTING ANODE DUSTING, C. THE CARBON ANODE BEING EXPOSED TO THE GASEOUS WATER EVOLVED FROM THE ALUMINA, WHEREBY ANODE DUSTING IS PREVENTED.

Abstract: An electrode assembly for use in an electrolytic cell having a corrosive environment comprising high temperature chlorine gas and a bath of aluminum chloride dissolved in one or more salts. The assembly comprises an electrode disposed within the cell, at least one electrical current conducting lead made of material susceptible to corrosive attack by the environment extending into the electrode, and a fluid impervious, electrically conductive sleeve disposed around the lead along at least the length thereof extending through a wall of the cell, and in contact with the electrode. The fluid impervious sleeve is effective to prevent contact of approaching corrosive constituents with the lead.
Abstract translation: 一种用于电解池的电极组件，其具有包含溶解在一种或多种盐中的高温氯气和氯化铝浴的腐蚀环境。 所述组件包括设置在所述电池内的电极，至少一个由容易受到延伸到所述电极中的环境的腐蚀性侵蚀的材料制成的导电导线以及沿着至少其长度设置在所述引线周围的不透液体的导电套筒 延伸穿过电池的壁并且与电极接触。 流体不可渗透的套管有效地防止接近腐蚀性成分与铅的接触。

Abstract: AN IMPROVED ELECTRRODE ASSEMBLY FOR USE IN AN ELECTROLYTIC CELL PERIMETRICALLY CONFINING A CORROSIVE FLUID ENVIRONMENT. INCLUDED THEREIN IS AN ELECTRODE ELEMENT EXPOSED TO SAID ENVIRONMENT, AT LEAST ONE LOW RESISTANCE CURRENT CARRYING LEAD OF MATERIAL SUSCEPTIBLE TO DELETERIOUS ATTACK BY CORROSIVE COMPONENTS OF SUCH ENVIRONMENT HAVING ONE END TRAVERSING A WALL OF THE CELL AND EXTENDING INTO THE ELECTRODE ELEMENT; THE OTHER END OF THE LEAD IS DISPOSED EXTERNALLY OF THE CELL WALL, AND A PLURALITY OF SLEEVE MEMBERS ARE DISPOSED AROUND A PORTION OF THE LEAD TRAVERSING THE CELL WALL TO INHIBIT CONTACT OF SAID CORROSIVE COMPONENTS WITH THE EXTERIOR SHELL OF SAID CELL AND WITH SAID LEAD. MEANS ARE PROVIDED FOR MAINTAINING A PROTECTIVE SHEATH OF INERT GASEOUS FLUID SURROUNDING THE LEAD MEMBER, AT A PRESSURE OF A MAGNITUDE SUFFICIENT TO REPEL AND THEREBY PREVENT CONTACT OF APPROACHING CORROSIVE COMPONENT WITH THE LEAD MEMBER.

Abstract: An improved electrode assembly for use in an electrolytic cell perimetrically confining a corrosive fluid environment. Included therein is an electrode element exposed to said environment, at least one low resistance current carrying lead of material susceptible to deleterious attack by corrosive components of such environment having one end traversing a wall of the cell and extending into the electrode element; the other end of the lead is disposed externally of the cell wall, and a plurality of sleeve members are disposed around a portion of the lead traversing the cell wall to inhibit contact of said corrosive components with the exterior shell of said cell and with said lead. Means are provided for maintaining a protective sheath of inert gaseous fluid surrounding the lead member, at a pressure of a magnitude sufficient to repel and thereby prevent contact of approaching corrosive component with the lead member.
