Filed: 1976-03-19
Abstract: 1512353 Removing gases during charging of coke ovens OTTO-SIMON CARVES Ltd 8 Feb 1977 [19 March 1976] 11073/76 Heading F4B and F4X In a system for removing and treating dustladen gases emitted during the charging of coke ovens and comprising a gas collecting main 13 formed as a continuous loop extending along one side of the coke oven battery with means being provided for selectively establishing connection between the main 13 and the individual oven chambers, the collecting main 13, which includes a fan 15 for circulating the gases therewithin, is provided with a heating jacket 26 to maintain the main 13 at a sufficiently high temperature to prevent condensation therein of tarry substances in the gases. The selective connection between the main 13 and the respective oven chamber being charged is achieved by a pipe 38 mounted on the charging car 35 and connectible at 39 to the oven chamber 37 and at 40, via a valve 14, to the main 13. The dust laden gases removed from main 13 through duct 16 are burned in a combustion chamber 17 having a primary combustion zone 19 and a secondary zone 22. Flow of air into the primary zone 19 is controlled by a valve 21 in proportion to the flow of gases in duct 16, and the secondary zone may be supplied with additional air and/or fuel if required. The burned gases leaving the combustion chamber 17 are fed to the heating jacket 26 via line 25 and, after passing through the jacket 26, are discharged to atmosphere via a wet scrubber 29. A portion of the burned bases may be used to purge the loop main 13 if the oxygen content of the gases therein, as sensed by an analyser 34, is too high, the burned gases being supplied through a duct 32 provided with a control valve 33. Alternatively steam introduced through a duct 44 may be used for purging purposes if the oxygen content of the burned gases leaving the combustion chamber 17 and sensed by an analyser 45 is found to be too high. When the charging of each oven chamber has been completed, that chamber is then placed in communication with a second collector main 12 via an ascension pipe 11 provided with isolating means 42.

Title: Process for the production of a gas of definite stoichiometric composition by the carbonisation of fuels
IPC: C10J3/64
Filed: 1936-04-21
Abstract: 461,402. Coking processes ; gas producers. DIDIER - WERKE AKT. - GES. April 21, 1936, No. 11378. Convention date, July 22, 1935. [Class 55 (i)] Gas of stoichiometric composition is obtained from fuels such as brown coal, lignite, flame coal, by preheating the fuel by external heating and removing the products, carbonizing the fuel in an externally heated chamber and leading the high temperature gas with steam through a body of incandescent coke resulting from the carbonization to effect the substantial conversion of the gases into the desired mixture of hydrogen and carbon monoxide. Fuel, e.g. in small pieces or briquettes, is fed through a preheating chamber 3 heated by waste gases supplied through a duct 8. Steam, carbon dioxide, hydrogen sulphide, and tar vapours are successively emitted as the fuel temperature rises to about 400‹ C. and are removed through off takes 11 ... 15. The fuel descends to a gasefication chamber 4 comprising a carbonization zone in the upper third of the chamber in which a temperature of at least 850‹ C. is maintained, a reaction zone into which steam is admitted at different levels through ducts 25, 26 and traverses the zone to an outlet 29 in admixture with the carbonization gases, and a water gas zone in which steam is admitted through inlets 27, the water gas generated being drawn off at the upper end and passing with the reaction gas through outlet 29. Or the water gas may be drawn off at the lower end as when the zone is formed as a separate chamber. The gasefication chamber is heated by the combustion of gas in flues 20, waste products passing through a recuperator 22 for preheating the combustion air or gas and thence to the heating flues of the fuel preheater. The mixed reaction gas and water gas may comprise 85-90 per cent hydrogen and carbon monoxide in the ratio of 2 or more than 2 to 1. For the treatment of brown coal the preheating, carbonizing, reaction, and water gas chambers may be of iron, silicon carbide material, silica material and fireclay respectively.

Abstract: 113,792. Cary, S. C. Aug. 22, 1916. Fastenings.-A corrugatel toothed fastener, as shown in Figs. 22 and 27, has a continuous cutting edge on the saw-tooth edge formed by bevels on the concave and convex surfaces with sharpened teeth points in the plane of the medial line of the fastener. They are mads by operating by means of vertically reciprocating dies D, E, F, G on one edge of a strip X, which has been corrugated by means of relatively adjustable rollers H, and is guided intermittently through a channel I in a plate A. The die D has a groove D', which produces bevelled surfaces s, s<1>, Fig. 19; the die E has a groove E<1> of larger angle than the groove D<1> and produces the bevelled edge s<2>. Fig. 20; the die F cuts away part of the bevelled surfaces s and produces a bevel t, Fig. 22, on the concave surfaces adjacent the bevels s; and the die G cuts the bevels s<1> in the same way. While the dies are operating, the work is held stationary in a guideway I by clamps K, L, M, which are normally pressed outwards by springs, and are forced against the work by the bevelled pieces K<2> 0, P when the dies descend. The sides of the guideway are oppositely inclined at the parts i i<3>, against which the work is clamped during the cutting operations. Another apparatus for pro ducing the fastener comprises relatively adjustable corrugating rollers 13, 14, milling-cutters 35, 36 which cut the bevels s on one side of the work and cutters 42, 43 which cut the bevels s<1> on the other side. The work is drawn continuously by relatively adjustable rollers 39, 40 through channels 54 and round a roller 37, and is pressed up to the cutters by spring-pressed plates 56 provided with adjusting screws 60. The cutters work ir recesses 53 in plates 52 forming part of one wal of the guide-channel 54. The strip is then drawn intermittently through a trimming apparatus simi lar to that shown in Fig. 1, except that the die D is omitted, and the die E may be omitted. The intermittent feed is effected by rolls 44, 45 rotatec by a pawl connected to a lever which is actuated by the reciprocating head carrying the trimming dies.

Title: Improvements in and relating to the production of carbon-poor chromium iron alloys
IPC: C21C7/00
Filed: 1938-04-14
Abstract: 513,915. Alloys. ANGELINI, V. April 14, 1938, No. 11544. Convention date, April 14, 1937. [Class 82 (i)] An alloy, suitable as an intermediate product in the manufacture of low-carbon chromium iron alloys, is produced by treating commercial ferro-chromium with a high or medium carbon content in an electric furnace with iron pyrites and manganese ore, by which means the carbon content is lowered. Lime and fluorite may also be added to the furnace charge. In an example, ferro-chromium containing 65 per cent. of chromium, 1.2 per cent. of silicon, and 30 per cent. of sulphur produced after the treatment an alloy consisting of 63.4 per cent. of chromium, 1.2 per cent. of carbon, 0.09 per cent. of silicon, 0.068 per cent. of sulphur, and 0.9 per cent. of manganese, the remainder being iron. The carbon and sulphur contents of the intermediate product may be further reduced by treatment with an oxidizing slag in an electric or Bessimer furnace, oxygen or air enriched with oxygen being blown into the melt. Treatment of the above alloy for 20 minutes in this manner resulted in an alloy containing 58.0 per cent. of chromium, 0.05 per cent. of silicon, 0.04 per cent. of sulphur, 0.06 per cent. of manganese, and 0.12 per cent. of carbon.
