Title: Electro-chemical Process for Cleaning Metal Surfaces.
Filed: 1899-10-03
Granted: 1900-10-03
Abstract: 19,785. Vereinigte Elektricitõts- Actiengesellschaft and Klaudy, J. Oct. 3. Cleaning; pickling.-A metal surface is electrolytically cleaned by first suspending it as a cathode in a salt solution to remove grease, and afterwards using it as an anode or cathode-according to the metal under treatment-in an electrolytic cell containing an electrolyte which can be regenerated. When treating iron, copper, copper alloys, and similar metals, they are arranged as anodes, and the electrolyte is one which will attack the metal, and form a soluble hydrate on the cathode. This hydrate will then combine with the acid of the metallic salt formed, precipitating the metallic hydrate, and re-forming the original electrolyte. For iron, sodium sulphate is the electrolyte employed. Zinc, aluminium, and like metals are treated when connected as cathodes, unattackable anodes being employed. In this case also, an insoluble hydrate of the metal is precipitated, by means of a secondary reaction between the soluble compound formed at the cathode, such as zincate or aluminate, and the acid set free at the anode. The electrolyte is withdrawn, either continuously or intermittently, is fined and filtered, and is then returned to the cell.

Granted: 1903-02-05
Abstract: 5559. O'Brien, J. O., [Palestini, L.]. March 6. Potash-alum ; silica.-Leucite is ground, crushed, and sifted or otherwise prepared for treatment with an acid. It may then be treated, in acidproof vessels, with sulphuric acid, the amount of acid being determined by making a preliminary test. The acid is first heated by a steam jet to 80‹ to 90‹ C., and the mineral is then added during agitation. Potash-alum and silica are formed. When the reaction has ceased, and the mass tends to harden, it is treated with hot water to dissolve out the alum, leaving gelatinous silica with the insoluble residue. Among secondary products which may be obtained are rare metallic salts, such as those of cµsium and rubidium. Alumina; aluminates; aluminium and potassium chlorides ; silica. - Leucite is prepared as before, and then treated with hydrochloric-acid solution. Double chloride of aluminium and potassium and gelatinous silica are formed. The double chloride may be purified and employed as such, or it may be treated (a) at a high temperature with steam to obtain hydrochloric - acid gas, alumina, and potassium chloride, or (b) with slaked lime to obtain a precipitate of aluminate of lime, and a solution containing calcium and potassium chlorides, which separate on crystallization. To render the double chloride of aluminium and potassium suitable for use in extracting aluminium, sea-salt may be added to it. Hydrochloric-acid gas may be used instead of the solution. Alumina; aluminium and potassium fluorides; hydrofluoric acid; hydrofluosilicic acid ; silica; silicon fluoride; silico fluorides.-The prepared leucite may be treated with hydrofluoric acid, either gaseous or liquid, in lead vessels. Silicon fluoride forms as a gas, and may be passed into water, to form hydrofluosilicic acid and silica. In addition, aluminium and potassium fluoride forms, and may be decomposed with steam at a high temperature to obtain alumina, potassium fluoride, and hydrofluoric acid. Or fluosilicates may be obtained and treated by known methods. Aluminium and potassium phosphates.-The prepared leucite may be treated with other acids, e.g., phosphoric acid, in which case aluminium and potassium phosphates are obtained suitable for use as a manure.
