Title: Improvements in or relating to the protection of iron and steel against fretting corrosion
IPC: C23F11/10
Filed: 1954-02-17
Abstract: A method of protecting iron and steel surfaces against fretting corrosion comprises applying to the surface a penetrated monolayer film formed by sensitized adsorption.  A penetrated monolayer is a monomolecular layer of a weakly polar amphipathic substance, which has adsorbed a more strongly polar amphipathic substance.  Sensitized adsorption is the adsorption of such a strongly polar substance (the sensitizer) by a metal surface to facilitate the subsequent adsorption by the surface of the weakly polar substance.  An amphipathic substance is one whose molecules contain a polar portion and a non-polar portion.  The iron or steel surface may have formed thereon by heat treatment or by chemical treatment a porous film, e.g. an iron oxide or phosphate, of which extends the range of sensitizers which may be used. Examples of sensitizers are alkyl or aryl sulphates, sulphonates, phosphates, phosphonates, amine or substituted amine, or salts of fatty acids, and the second substance is a sterol, e.g. cholesterol or alkyl or aryl alcohols or amines. The two compounds may be applied to the surface simultaneously as an oil-water emulsion, e.g. equal volumes of sodium dodecyl sulphate in water and cholesterol in British Pharmacopeia paraffin.  An alternative emulsion, applied to a phosphated mild steel surface, was 0.36 gm. cetavlon in 100 mils water and 0.39 gm. cholesterol in 100 mils British Pharmacopeia paraffin.  The emulsion may be heated to 60 DEG C. during application to the surface.

Title: Improvements relating to processes for the reduction of metallic oxides or metal oxide ores
IPC: C21B13/02
Filed: 1946-12-16
Abstract: In the reduction of metallic oxide or metal oxide ore, a preheated mixture of hydrogen and nitrogen is passed repeatedly over the oxide or oxide ore.  The hydrogen consumed by the reduction may be replaced by the addition of fresh hydrogen, with or without fresh nitrogen, and some of the cycling mixture may be bled off at each pass to remove excess impurities such as hydrocarbons and carbon monoxide. Ferric oxide may be formed into porous nodules as described in Specification 630,089, preheated to 600 DEG C. by the hydrogen content of part of the bleed gas, and charged into a shaft furnace into which the preheated gas mixture is introduced preferably at varying temperatures, the higher temperature mixture being introduced above the lower temperature mixture.  The gas mixture passes upwardly through the furnace, and on leaving, it is cooled, scrubbed, passed through a compressor, preheated to 1,000 DEG C. partly by the hydrogen content of part of the bleed gas and partly by heat exchange with the hot mixture leaving the furnace, and then again introduced into the furnace. The gas mixture may contain 20-70 per cent hydrogen, and reduction at 700-1,000 DEG C. may be completed in about 1-1 1/2 hours.

Abstract: 397,032. Metallic-vapour apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. fur Elektrische Gl³hlampen, 11, Ehrenbergstrasse, Berlin.) Feb. 18, 1933, No. 5070. Convention date, March 4, 1932. [Class 39 (i).] In a discharge device such as a lamp or a rectifier having a liquid cathode and a directly or an indirectly heated thermionic cathode to facilitate starting, the cathodes are separated one from the other, and are not connected within the device by any metallic conductor. A potential from a transformer 5, Fig. 2, is applied between an anode 2, the mercury cathode 3 and a thermionic cathode 4 through ballast resistances 6, 7. The resistance 7 may be used to regulate the currents flowing to the cathodes, such that only a small fraction, e.g. a third, of the current flows to the thermionic cathode. Heating of the cathode 4 is effected through a transformer 8. Starting is facilitated by the application between the cathode 4 and an auxiliary anode 10 of a potential from a separate source 9 the phase of which may be displaced from that of the source 5. A discharge tube 11 in series therewith controls the discharge current and delays the starting thereof. In a modification, the thermionic cathode is protected from positive ion bombardment by housing it within an extension 1<1>, Fig. 7, and surrounding it by an auxiliary anode 12 in which is formed a slit 13 for the passage of the electrons. The potential drop between the thermionic cathode and the auxiliary anode 12 should be less than the sputtering voltage. Funnel like constrictions 14 facilitate starting and prevent shortcircuiting of the electrodes by the condensate. Grids may be used to control either or both the auxiliary and main discharges. The thermionic cathode may consist of tungsten coated with electron emitting substances, and leading-in wires may be connected to intermediate points thereof to enable sections of the cathode to be used.
