Title: Process for producing pig iron in rotary furnace
IPC: C21B11/06
Filed: 1962-10-08
Abstract: <PICT:0991579/C6-C7/1> Pig iron is produced in a furnace rotating at not less than 10 r.p.m. about an axis inclined at not more than 45 degrees to the horizontal by forming therein a body of slag and carbonaceous material at a temperature not exceeding 1450  DEG C. and supplying on top of said body comminuted ore and carbonaceous reducing agent in such proportions that a layer of molten iron containing at least 2% and preferably 3% of carbon is formed below the slag. Oxygen or oxygen-rich gas is blown in above the slag in such a way that the reducing conditions at the bath surface are not impaired, the carbon monoxide evolved in the reduction layer burning therewith to provide the necessary heat for the process. An acidic slag may be used or, when phosphorus-rich materials are to be reduced, carbonates and/or oxides of calcium and/or magnesium are added together with pieces of carbonaceous matter sufficiently large to float on the slag, and the conditions are then so regulated that the iron oxide content of the slag is at least 2% calculated as iron. The iron ore charged may have been partially pre-reduced to metallic iron, and the process may be operated either continuously or batchwise. As illustrated, rotary furnace 1 is charged with ore and reducing agent from hopper 23 by a blast of air or natural gas from pipe 24, thereby forming metal layer 5, slag layer 6 and reaction layer 7. Oxygen is blown in through pipes 26, 27, and the exhaust gases escape through opening 11.

[Class 6 (ii).] Apparatus for igniting bonfires in fields to protect crops from frost &c., comprises devices controlling the automatic ignition of the bonfires and connected by wires to instruments adapted at a predetermined temperature and time to release those devices controlling the ignition of those bonfires placed to windward of the field. A fire is lighted when two tubes 1, 2, Fig. 7, are allowed to fall upon it, the tubes being filled with materials which ignite when mixed. The tubes 1, 2 are normally held up by wires W passing up tubes into a sectional tank Y above which is mounted a receptacle X on the vertical shaft of a wind-vane. A pivoted tube V containing strong acid is normally held in an approximately vertical position by a wire t and by a pivoted plate I held in position by a pivoted lever G engaging in a hole in it. When the wire t and plate I are both released the tube falls and discharges the acid into a cup Z, thus destroying a wire supporting a pivoted tube U containing acid, which is discharged, by the fall of the tube, into the receptacle X. The acid passes through a hole in the vessel X into one or other of the sections of the tank Y, according to the direction in which the wind-vane points, and destroys the corresponding wire W, thus releasing an igniting device 1, 2. Each wire W may be connected to a series of igniting devices. The wire t ends in a ring K engaging over a projection on a pivoted lever Q, and is released when the lever Q is moved by a striker actuated by a relay P in the circuit of a battery M, on the circuit being completed by the engagement of the pointer of a contact thermometer with an adjustable stop.

Patent GB-1006515-A (GB)
IPC: C08B11/08
Filed: 1962-10-09
Abstract: A process for preparing a polysaccharide ether wherein alkali is chemically consumed during etherification of the polysaccharide, the ether consisting of a starch or cellulose ether of highly uniform substitution and high salt tolerance, comprises contacting the polysaccharide with alkali to condition it for subsequent etherification, the amount of alkali in this step being substantially in excess of the amount required for the etherification, then reducing the amount of alkali and etherifying the alkali polysaccharide in the presence of such reduced amount of alkali, the reduced amount of alkali being from that required for etherification up to 10% in excess of that amount.  The alkali content may be reduced after the alkali conditioning step but before addition of the ether ifying agent.  Removal of the alkali, e.g. sodium hydroxide may be effected by washing, solvent extraction or by addition of an acid. The etherification may be carried out on a slurry of the polysaccharide in aqueous alkali and a diluent, e.g. a lower aliphatic alcohol, or the process may be carried out on polysaccharide in the dough or semi-dry state. The ethers prepared may be carboxyalkyl-; carboxyalkyl alkyl-; carboxyalkyl hydroxyalkyl-; alkyl-; sulphoalkyl- or phosphonoalkyl-ethers.  In examples, a slurry of comminuted cellulose is aged with a mixture of aqueous sodium hydroxide and isopropyl alcohol for 2 hours at 15 DEG C., and the cellulose then etherified at 70 DEG  C. by adding a mixture of monochloroacetic acid and isopropyl alcohol in presence of glacial acetic acid to reduce the alkali content.  The resulting carboxymethyl cellulose is hardened in methanol.
