Abstract: 513,451. Vitreous enamelling. I. G. FARBENINDUSTRIE AKT.-GES. April 11, 1938, Nos. 11052, 11053 and 11054. Convention dates, April 22, 1937, May 3, 1937, and May 3, 1937. [Class 56] A process for enamelling metal consists in first coating the surface of the metal with a porous intermediate layer which is capable of uniting with the enamel when the latter is fired, and then depositing on the surface through the porous layer a metal which roughens the metal to be enamelled. When enamelling iron, the metal may be cleaned and freed from oxides either mechanically or by pickling, and is then coated with the porous layer. This may be a fritted material consisting of silica with alkalies, boric acid, lime, and alumina; or it may be a non-fritted material composed of a self-hardening layer of frit containing waterglass with any usual inorganic or organic binding-agent if required. The roughening metal, which may be iron or nickel, is then deposited through the porous layer either by spraying, or by the decomposition of a liquid or gaseous metal compound such as a carbonyl, or electrolytically. Finally, the enamel is applied and fired.

Title: Improvements in or relating to process of and apparatus for production of carbon black
IPC: C09C1/50
Filed: 1948-04-24
Abstract: Carbon black is produced by introducing vaporous hydrocarbon as an axial stream into one end of a generally cylindrical reaction zone having a reduced choke por <PICT:0679820/III/1> tion the length of which is greater than its mean diameter and an enlarged outlet portion connected axially downstream, the centre of the choke portion being upstream of the centre of the reaction zone, introducing free-oxygen-containing gas into the reaction zone upstream of the choke as a rotating stream enclosing the axial hydrocarbon, burning a portion of the hydrocarbon with the oxygen to decompose a portion of the hydrocarbon to carbon black, cooling the effluent gases and separating carbon black therefrom. The hydrocarbon, e.g. gas oil, kerosene, gasoline, pentane, hexane, coal or shale distillates, which may be preheated to 675 DEG F, is injected through pipe 18, with or without air from annular jacket 19, into refractory lined furnace 13, having insulation 15, enclosed in steel shell 14.  Air is introduced through one or more tangentially directed ports 22 and forms a helical layer of flame and combustion products along the wall of combustion section 10, choke section 11, and outlet section 12, which prevents carbon deposition.  The effluent passes through water jacket cooler 27, water spray 26, air cooler 28, to separator 29, whence carbon black is removed.  The tapered portion 16 facilitates a certain amount of mixing between the helical outer layer and the axial hydrocarbon and promotes stream-line flow.
