It enters the compartments in succession, beginning at the lowest one D<1>, then the lowest D', then the next lowest D', and so on to the highest compartment. Should the pressure within the casing A, which forms the holder, increase, the water is driven back through the siphon, and finally, if the pressure still increases, the acetylene can escape, by way of the siphon, to the outer air. The end or cover C of the casing A is removable, being adjustably secured by nuts c, and it is provided with a gas-purifying box 0 through which the gas has to pass to the outlet P.
Patent GB-189904643-A (GB)
Title: Improvements in and relating to the Manufacture of Nitric, Nitrous, and Sulphuric Acids and Oxides of Nitrogen.
Inventor: MCDOUGALL ARTHUR
Filed: 1899-03-02
Granted: 1900-03-02
Abstract: 4643. McDougall, A. March 2. Nitric acid nitrogen oxides ; nitrous acid ; sulphiric acid.-Relates to a process for producing oxides of nitrogen and nitrous and nitric acids by combustion of air, consisting in passing the air through a vessel or vessels in which are placed the terminals of an electric circuit or circuits between which terminals a high-voltage alternating electric-current discharge takes place, producing a flame of burning nitrogen, the resulting products being afterwards collected and condensed, or, if desired, employed in the manufacture of sulphuric acid. The generators employed consist, in the arrangement shown, of six sets of earthenware or like conical vessels A arranged as six spokes of a wheel, each set having a lower air-supply pipe E, and an upper vapour-collecting pipe D. Each vessel is provided with a pair of adjustable terminals B, formed of a highly-infusible alloy of platinum and iridium, or of copper or carbon provided with tips of such an alloy. The electrodes are connected up in parallel with an alternating-current dynamo V, or with transformers, a choking-coil V' being used for each vessel. The current is distributed at about 5000 volts pressure. Each pair of terminals is arranged to slide in its insulators C, by means of bracket-pieces g, the roller ends of which gear with spiral slots f cut in adjusting-discs e. The terminals are brought within sparking distance, and then separated. The air, or air mixed with oxygen, is forced by a rotary blower J between the terminals, and the nitrogen burns. The vapours may pass directly to sulphuric-acid chambers, or may pass, as shown, to a series of condensing-towers H, each divided into two parts by a partition m, the upper part being filled with broken glass &c., and the lower with liquid which rises some distance above the partition. Down each column trickles water or sulphuric acid from an overhead tank L. The unabsorbed vapours and gases pass to a mixing-tank I, from which they are returned by the blower to the generating-vessels. Samples of the gases may be withdrawn for testing through the cock W, while fresh air may be admitted through the tap X, and oxygen through the taps Y or Z. The dilute acid leaving the condensers passes through siphon tubes N to closed tanks O, and from thence through pipes P having cocks T to other closed tanks Q. From the latter it may be forced, by compressed air admitted from the tube S, back to the overhead tanks L through the tubes R. When of the desired density, the acid may be drawn off from any of the tanks by cocks or siphons. In a modification, the generators are arranged in a number of tiers on a double series of shelves, forming a battery of 500 generators.

Abstract: 11,930. Michel, T., Wilhelm, I., and Richard, H. J une 8. Chlorine. - Relates to electrolytic apparatus especially intended for electrolysing alkaline chlorides, and more particularly sodium chloride to obtain soda and chlorine. The cell o is divided into two fluid-tight compartments m, n by a partition b. The former compartment contains an anode a and brine, and the latter a cathode c and a dilute caustic solution. An intermediate electrode, consisting of a travelling endless gauze band d passing round rollers s, s<1>, s<2>, s<3>, s<4>, s<5>, passes alternately through the two compartments in the direction indicated, and dips into a mercury seal r at the lower end of the partition, which is arranged in a well formed in the cell. A partition l, having a rubber strip l<1> bearing against the gauze, cuts off any upper communication between the two compartments. When in use, chlorine is liberated in the compartment m and escapes by the outlet e, while the mercury carried by the intermediate electrode forms an amatgam with the sodium. This amalgam is then curried to the compartment n and decomposed, hydrogen being evolved and escaping through the outlet f, caustic soda being formed, and mercury passing back to the well. The electric, energy resulting from the decomposition of the amalgam contributes to the electrolytic work. Inlets and outlets 1, 2, 3, 4 are provided, for connecting several cells, and for circulating the liquids.
