    摘要: The cathode region of a sodium sulphur cell has hitherto sometimes been sealed by a thin metal member welded at its outer periphery to the metal casing and at its inner periphery to the alpha alumina lid of the electrolyte. The welding operation damages the essential protective coating of the thin metal member. This invention discloses sealing the cathode region with a thin metal member (5) secured to a concentric outer thicker metal member (4), the thin member being sealed to the lid (15) and the thicker member being sealed to the casing (1). The thickness of the outer member eliminates the need for a protective coating so that the combined seal has greater integrity than previous seals.

    摘要: In a pass-through sintering furnace for sintering a succession of ceramic tubes fed lengthwise through the furnace and rotated as they pass through the furnace, the tubes, when heated in the furnace, are kept apart by pushing each tube into the furnace at one end and pulling it out from the other end. The pulling speed is less than the pushing speed to ensure uniform firing throughout the length of the tube, allowing for shrinkage as the tube is fired, but is sufficient to hold the pulled tube clear of the next following tube so as to obviate any pushing against the end of a hot tube.
