Title: Process and apparatus for the preliminary and final refining of pig iron by air
IPC: C21C1/00
Filed: 1938-01-24
Abstract: 514,352. Pig iron and steel; converters. ROCHLING'SCHE EISEN-UND STAHLWERKE GES. Jan. 24, 1938, Nos. 2237, 2238 and 2239. Void. Convention dates, Jan. 23, 1937, Jan. 28, 1937 and Nov. 10, 1937. [Class 72] In the refining of pig iron or production of steel in a converter, the molten pig iron is caused to flow uniformly through a converter and is converted into steel by the use of air, oxygen or enriched air, and the iron refined in one converter may be finished in one or more similar converters connected in series with the first converter. The supply of pig iron to the converter may be maintained constant by hand based on the indications of measuring apparatus, or automatically by regulators so that the composition of the metal in the separate stages is regulated accurately. The steel produced may be deoxidised either in a separate vessel or in an extension of the converter which is filled with protective gas. The finished steel may be cast under exclusion of air into small ingots which can be immediately rolled in a billet mill train. The pig iron before treatment in the converter may be desulphurised with alkalies and solid or liquid refining or deoxidising agents may be added to the iron as it flows through the converter. The converter comprises a horizontal drum A, provided with a reduced end section Q having a feeding trough H and an outlet M<2> for waste gases, and with a middle elongated portion D having air nozzles E communicating with a chest F to which is connected an air conduit G rotatably mounted in a stuffing box X. The chamber D is provided with a transverse dam O<1> a slag outlet L, and an inlet N for refining additions to the metal flowing through the converter, which is also provided with a reduced end portion R in which the metal is deoxidised and which is provided with a transverse dam 0 <2>, apertures M<1> and V, a second dam T, and a syphon outlet K for the finished steel. Waste gases, which may be used for pre-heating the refining or deoxidising additions, escape through the aperture M<1> and the deoxidising additions are fed in through the aperture V. If desired the chest F may be divided so that the iron may be treated with different gaseous agents, e.g., first with oxygen, and then with air.

Title: Improved continuous process and apparatus for the production of large quantities of absolute alcohol
IPC: B01D3/00
Filed: 1923-01-26
Abstract: 192,410. Barbet et Fils et Cie, E. Jan. 26, 1922, [Convention date]. Addition to 189,136. Alcohol, dehydrating. - In the process described in the parent Specification, the necessity for the employment of two stills, working alternately to permit of scaling, is obviated by the interposition of a decanting device between the mixer and the still. Alcohol of 96<0> Gay-Lussac and mean temperature 70‹ C. is mixed with quicklime in a dehydrator A, whence after some hours it is run into the decanting device B, where the hydrated lime sludge sinks into the lower cone, passes through the valve C operated by a hand-wheel V and enters a continuous rectifier K L together with a quantity of luke-warm water from the measuring-device D. The clear alcohol is decanted into the still H with steam jacket h, where it is distilled as in the parent Specification. When the distilling power of the still H is impaired by the formation of scale on the heating surface, the supply of alcohol from B is stopped and the scale removed by hand or by introduction of diluted hydrochloric acid through the hand-hole U, the liquid being discharged by the cook X. After the scale is completely removed the still is dried by heating slightly and the distillation resumed.

Title: An improved process for obtaining sulphur from spent gas purification masses
IPC: C01B17/027
Filed: 1933-01-26
Abstract: <PICT:0399069/III/1> In the recovery of sulphur from gas purification masses by distillation by the passage thereover of heated combustion gases, contamination of the sulphur by entrained gas purification dust is prevented by using the combustion gases for indirect heating, only so much, about 1 per cent, of these gases as will carry off the sulphur vapour being led over the material under treatment. Prior to the actual distillation, the material is dried by heating at 250-350 DEG  C. by flue gases, preferably those from the distillation step, a small part being led over the material to remove the water vapour. During this preliminary heating, the tar content of the material is mainly decomposed and carbonized. In the apparatus shown the dried material to be treated is fed by a passage 4 to a retort 3 heated to 600 DEG  C. by combustion gases which may be derived from a furnace 12 and are led into the space round the retort near the lower end thereof, the exhaust gases passing through a preheater 10 before reaching the flue 1.  The small amount of combustion gases required to carry off the sulphur is drawn in by the flue draught at slots 7, the gases passing by a pipe 5 to a condenser 6 heated to keep the sulphur fluid and then through a water-cooled condenser 9; finally the gases enter the flue 1 by a pipe 11.

Abstract: 698,043. Sheathing electric cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Feb. 8, 1951 [Feb. 9, 1950], No. 3383/50. Classes 83 (ii) and 83 (iv). [Also in Group XXXVI] Drawing.-An electric cable is sheathed by laying out a length of metal tube, pulling the cable into the tube and then drawing down the tube, that part of the cable which initially projects from the tube, but is subsequently covered by the elongation thereof, being protected and guided by a tubular casing attached to the end of the tube. A length of aluminium tube 13, is drawn through a straightening die 15 on to a support 16, 17 by means of a hawser 18, and a tubular casing built up from a number of sections such as-22, 23, is placed adjacent the end of the tube. When the tube is in position the end is severed to release the hawser 18, and a tow-line 27 attached to a plunger is blown through the tube by means of compressed air. The plunger is then removed and the tow line secured to the hawser at one end and to the cable core 26 at the other, to draw the core through the tube 13 and casing 22, 23, Fig. 6. The end of the casing 22 is attached to the adjacent end of the tube 13 by means of a link 33. The other end of the tube, together with the cable core 26, is attached to a hawser 34 which passes through a reducing die 24. The tube and cable core are drawn through the die, which is of such a size that it reduces the tube to be a sufficiently tight fit on the cable core. When the trailing end of the tube approaches the die it is detached from the casing 22. The initial length of the tube 13 is such that after the drawing down operation has been completed the whole length of the cable core 26 has been sheathed. In an alternative method the protective casing may consist of a single length of metal tube which is pulled on to the support at the same time as tube 13. Specification 698,044, [Group XXVIII], is referred to.

Title: Improvements in the manufacture of yarns
IPC: D01G1/10
Filed: 1932-02-05
Abstract: 397,138. Producing imitation spun yarn from filamentous material. BRITISH CELANESE, Ltd., 22, Hanover Square, London, TAYLOR, M. M. and FULTON, S. M., c/o British Celanese, Ltd., Spondon, near Derby. Feb. 5, 1932, No. 3467. [Class 120 (iii).] In order to produce yarn from continuous filaments having the appearance of spun yarn, that is yarn made from staple fibre, a continuous filament bundle is subjected to the action of cutting means, particularly abrasive means, between which and the filaments there is relative movement to ensure severance of the filaments. The cutting operation is such that at any one point one or relatively few of the filaments are severed, and to facilitate the distribution of the points of severance the cutting may be effected by a relative movement of the cutting-means transverse to the bundle. To produce a curly, wool-like effect the yarn may be subjected to a scraping action immediately before being torn. The process may be applied to any continuous filament yarn, for example to yarn of cellulose acetate or other organic derivatives of cellulose or of reconstituted cellulose, to natural silk, or to a mixture of such filaments. A yarn of broken filaments may be doubled with any other yarn and with one or more other broken filament yarn. The yarns may be lustrous artificial filaments or may be of subdued or reduced lustre. The yarns may be introduced into the warp or weft or both of woven fabrics to produce the appearance of a fabric composed of staple fibre yarns, or to produce local patterns or effects, and may be used as effect materials or the sole or principal constituents of knitted fabrics. As shown in Fig. 1, yarn from a twisting-spindle, such as described in Specification 304,806, [Class 120 (ii), Spinning, twisting, &c.], passes to a drum winding-device 19, 20 over a glasspaper or emery covered roller 24 which may be stationary or rotated in either direction and effects the cutting of the filaments. A dull knife edge 26 is arranged to divert the yarns slightly whereby, upon being broken, they recoil and assume a curly formation. The yarn may pass through a rotating tube lined with emery or glass paper, or may pass between a pair of abrading discs such as described in Specification 328,247, [Class 120 (iii), Yarns &c.], for delustring artificial yarn, roughcutting powder, if desired, being ejected from a pipe 46, Fig. 4, on to the discs 38, 39, and the yarns being delustred as well as cut. Fabric or fur-covered rollers 45, Fig. 3, rotating in a direction opposite to that of the travel of the yarns serve to lay the protruding fibre or beard. In the arrangement shown in Fig. 3 the yarn is twisted by a ring twisting-device 41 after being cut. The roughened yarn may be subjected to a gassing or other operation for removing " beard."
