Title: Improvements in or relating to electric resistance furnaces and heating elements therefor
IPC: H05B3/64
Filed: 1942-04-29
Abstract: 557,108. Electric resistance furnaces. SWIFT, LEVICK & SONS, Ltd., TETLEY, F. W., SIEMENS-SCHUCKERT (GREAT BRITAIN), Ltd., and KIRKUP, R. W. April 29. 1942, No. 5739. [Class 39 (iii)] [Also in Group XXII] Electric furnace resistance heating elements are made by casting a heat resisting alloy into such length and, cross section that it has the required strength and electric resistance. A casting method which gives a skin of such depth as to minimize the effects of scale formation may be used, e.g. a rectangular cross section of ¢ inch Î # inch is cast in green sand. A coarse sand may be used, to provide a rough surface which increases thermal efficiency. An iron alloy which may be used comprises chromium 22.5-23.5 per cent., aluminium 5-5.5 per cent., cobalt 1.6-2.0 per cent., manganese 0.3-0.5 per cent., silicon 0.35-0.45 per cent., carbon up to 0.08 per cent., preferably with titanium up to 0.5 per cent. The resistance may be straight, or in grid form, Fig. 1, either flat or arched. Two lengths may be welded together, and each length end may be brought outside the furnace for welding to an adjacent length or connection to a current supply. The extensions are preferably formed as required, by casting, or straight lengths may be bent. The grid may be cast or bent to an arched shape to cover the sides and roof of a furnace, and may be partly embedded in the lining, the bars being separated by tongues of the lining projecting at intervals between the bars. Alternatively, several grids may be required to span the roof and sides, and they may be wholly embedded. In a rectangular furnace, Fig. 8, a heating grid 10 is wholly embedded in the roof, other grids 10 are partly embedded in the sides to be flush with the surface, and the floor is heated by flat grids, the bars of which are separated by tongues 16 extending above the surface to form a support for articles in the furnace.

Title: Process for the conversion and methanisation of carbon monoxide-containing gases
Inventor: SCHIERENBECK JULIUS
IPC: C10K3/04
Filed: 1955-02-25
Abstract: 791,946. Enriching gases containing carbon monoxide. KOHLENSCHEIDUNGS - GES. Feb. 25, 1955, No. 5789/55. Class 55 (2). In a process for methanizing gases containing carbon monoxide by reacting some of the carbon monoxide with steam to form carbon dioxide and hydrogen and then reacting a further quantity of the carbon monoxide with hydrogen to form methane and steam, the heat generated is transmitted before completion of the methanization to the gas to be methanized and part of the heat transmitted is used to vaporize water in the gas thus heated to provide the steam necessary for the process. In the drawing gas to be methanized or passed through heat exchangers 1, 4 and 5 and water is sprayed into the preheated at 2 and if necessary also at 2<SP>11</SP> to provide steam for the first stage of the process in which carbon monoxide and steam are reacted together. This reaction is effected in reactors 6 and 7, water may be sprayed into the gases at 2<SP>1</SP> if more steam is required for the reaction in reactor 7. Gases from the reactor 7 are cooled in heat exchanger 5 to between 250‹ and 300‹ C. before passing to a reactor 7 containing a catalyst promoting the formation of methane from carbon monoxide and hydrogen. From reactor 7 the gases are passed through heat exchanger 1 and are again cooled before entering a second methane-producing reactor 8, methane enriched gases are withdrawn via heat exchanger 4 wherein they are cooled to between 200‹ and 250‹ C. and are subsequently further cooled and scrubbed to remove carbon dioxide. In a modification, the methane-producing reactor is in tubular form and the gases to be methanized are passed first through a body of water and then preheated in passing round the tubular reactor, water entrained in the gases being vaporized.

Title: Improvements in the manufacture and production of oxygenated organic compounds
Filed: 1928-02-24
Abstract: 312,388. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 24, 1928. Oxygenated organic compounds.-Oxygenated organic compounds are obtained by passing a gaseous oxidant at a raised temperature through liquid benzine hydrocarbons boiling below 180‹ C., a distillation during the process being avoided. The process is preferably conducted at 80-200‹ C. and may be carried out under pressure and (or) with the use of catalysts such as the resinates, oleates, enolates or other organic compounds of the alkali or alkaline-earth metals, magnesium, aluminium, or manganese. Solid .bodies of large superficial area, such as masses of aluminium or its alloys, may also be present, being preferably arranged so that they protrude above the liquid surface. The oxidant may be air, oxygen, or nitrogen oxides, and the risk of explosion may be avoided by diluting the oxidant or by adjusting the conditions so that the gases leaving the liquid are sufficiently deoxidized. According to the examples, (1) hexane mixed with a little manganese acetylacetonate is treated with air at 145‹ C. under 20 atm, pressure in an aluminium-lined tube charged with fillers and cooled at the upper part, and (2) a benzine boiling at about 70‹ C. is oxidized in the same apparatus and under similar conditions with air diluted with carbon dioxide, no catalyst being employed: the products in each case comprise fatty acids and their esters. Specification 303,268 is referred to.
