摘要： A portable hydrogen and oxygen supply system produces gaseous hydrogen and gaseous oxygen from water. It separates the gasses and vents them into two separate chambers. The supply system creates water disassociation through an array of concentric hexagonal hydrogen collector tubes, anode rods and a cathode matrix, all of which are submersed in water. The anode rods and cathode matrix are supplied DC electrical current. The water separates (disassociates) as atomic hydrogen is drawn to the negatively charged anode rods and the atomic oxygen is drawn to the positively charged cathode matrix. The hydrogen, on its path to the anode, passes through the walls of the hydrogen collector tubes to be collected in the first chamber. The oxygen is unable to pass through the walls of the tubes, and remains outside the tubes to be collected in the second chamber.

摘要： Conventional fused salt reduction cells feature anode conductor sections which are spaced apart and have the function of feeding electric current to the anodes via anode rods. An electrically insulated footbridge positioned over the cell between the anode conductor sections makes it possible to walk above the cell. A housing with slight positive pressure created by the supply of fresh air to it, is preferably provided over this footbridge. Transverse cells are arranged asymmetrically in a pot room. An air-tight, closeable walk-way i.e. gangway is provided on the inside or outside of the long wall of the pot room. Extensions to the cell housings lead to appropriate openings in the long wall of the pot room or to the longitudinal wall of a gangway in the interior of the pot room. The fresh air is passed through the gangway and emerges from the open end of the cell housing.

摘要： A cell for fused-salt electrolysis for reducing alumina in the presence of cryolite to metallic aluminum. The cell includes an insulated tank having a carbon bottom, two rows of anode rods disposed on opposite sides of an anode carrier positioned in the longitudinal center plane, an exhaust gas-collecting duct extending at the longitudinal center between the two rows of anode and covers downwardly inclined from the outside of respective rows of anode rods to respective edges of the tank and provided at the outer longitudinal edge and the transverse edges with a skirt that extends to the respective edge of the tank. Each cover is hinged adjacent to its longitudinal edge adjacent to the anodes and at least at its corner portions to a support which extends along the row of anode rods. A carrying arm is secured to each end portion of the support and is pivoted at its other end to the anode carrier. The carrying arm is connected by an operating linkage to a piston rod of a cylinder of a hydraulic or pneumatic actuator. A second cylinder of a second hydraulic or pneumatic actuator is pivoted to the support at least adjacent to the middle thereof and the piston rod of the second actuator engages the cover.
