Title: Improvements in, and relating to the Production of Hydrocyanic Acid.
Inventor: FELD WALTHER
Filed: 1902-09-26
Granted: 1903-07-30
Abstract: 21,017. Feld, W. Sept. 26. Hydrocyanic acid.-Relates to improvements by which loss of mercury is avoided in the process described in Specification No. 24,920, A.D. 1901, for the production of hydrocyanic acid from acid, neutral, or alkaline matters by treating them with mercury compounds to produce mercury cyanide and then distilling this cyanide with an acid. The alkaline or neutral bodies containing soluble or insoluble ferric or ferrous cyanogen compounds, with or without preliminary treatment with excess of a hydrate, oxide, or carbonate of an alkali or alkaline earth, or of magnesia, are treated with mercury oxide or other mercury compound without the addition of the salts referred to in the abovementioned Specification. The excess of mercury compound will be precipitated with the iron hydroxide &c., leaving mercury cyanide in solution. The precipitate is separated and treated, after oxidation in the case of ferrous cyanogen compounds, with one of the salts referred to in the above-mentioned Specification, viz., a salt of magnesium, zinc, aluminium, manganese, or other metal, the hydrate, oxide, or carbonate of which does not precipitate mercury or mercury oxides from solutions of mercury compounds, whereby the mercury oxide dissolves and can be used again. If the solution contains too much saline matter in solution, the mercury oxide or the like is precipitated, washed, and re-dissolved. If it be desired to prevent the precipitation of mercury oxide or the like, the iron cyanogen compounds are preferably first converted into ferri-salts of alkaline earths, and these salts are treated with the mercury solution and with a solution of one of the abovementioned salts. The mercury-cyanide solution is separated and treated with an acid, such as sulphuric or phosphoric acid, forming insoluble alkaline-earth salts, which are filtered off together with the iron oxide precipitated from the next batch of ferricyanide.

Abstract: 23,558. Ven, F. J. A. M. van der, and Dreessen, H. Oct. 28 Stone, artificial.-Artificial marble is prepared as follows :-The smooth surface of a sheet of glass, enamelled iron, &c. is coated by means of a brush with a thin layer of soft cement or of plaster of Paris and water. If several colours are used for this coat, which forms the ground colour of the marble, they are put on side by side in irregular and overlapping streaks. Before this coat is dry a thicker mass of the same material, of different colours, is thrown on at random in small lots or heaps, which are flattened down to fill in the spaces left between them. On the rough surface thus formed a layer of uniformly-coloured material is placed. This final layer is smoothed. Marble veined throughout may be prepared by repeating the variously-coloured layers and dispensing with the layer of uniformly-coloured material.
