Title: Method and apparatus for treating textile materials
IPC: D06B5/12
Filed: 1972-03-23
Abstract: 1365754 Treating textiles NIELS BERGHOLTZ & CO K/B 23 March 1972 [24 March 1971] 13548/72 Heading D1L Textile material e.g. polyacrylonitrile fibres, is treated e.g. dyed or bleached or washed with liquid in a plant comprising at least two compartments or groups of compartments containing the material covered with liquid by making the liquid flow through a first set of compartments whilst blocking off the passage of liquid through the other set of compartments, opening up the passage through the other set of compartments whilst blocking the passage through the first set of compartments and continuously repeating this intermittent flow pattern during the time required for the treatment. As shown schematically in the Figure, an autoclave 1, denoted by dash-dotted lines comprises two main compartments 2 and 3 for the textile material to be treated and four further compartments 2a, 2b, 3a, and 3b. In each compartment is a material carrier 5 e.g. a perforated rod, for carrying the material to be treated. Each carrier is connected to a conduit 6, 6a, 6b, 7, 7a and 7b respectively. The conduits 6 and 7 are each connected to one port of valve 8 having three ports and the third port is connected via conduit 9 to a pump 10 driven by a motor 11. A twoway valve 12 having four ports is fitted into conduit 9 between valve 8 and the pump 10, and a return flow conduit 13 from a collecting header at the top of the autoclave is also connected to valve 12. This conduit is connected downstream of valve 12 by conduit 14 connected to the pump. Valves 8 and 12 operate automatically. In operation, chosen time intervals for switching valves 8 and 12 from position I to II are preset in monitoring device 16. As shown compartments 2, 2a and 2b are connected to pump 10 while conduits 7a, 7a and 7b to compartments 3, 3a and 3b are blocked off and thus the liquid in these latter compartments are at rest. When valve 8 is set in position II, conduits 6, 6a and 6b will be blocked whilst compartments 3, 3a and 3b will be connected to the pump and liquid flow therethrough will take place. On each occasion liquid is transferred back to pump 10 by conduit 13, valve 12, and conduit 14. For a reversal of the direction of flow of the liquid through the material, valve 12 is switched from position I to II whereby pump 10 is conducted to conduit 13 while either conduit 6 or conduit 7 is connected to conduit 14 and to pump 10, and since one of the latter conduits is always blocked off, return flow from only one group of containers can occur. Openings are provided in the bottom wall of the autoclave for introducing heating medium e.g. steam or hot water.

Filed: 1922-05-13
Abstract: 198,545. Hechenbleikner, I., and Oliver, T. C. May 13, 1922. Acids, concentrating.-Sulphuric acid which has been used in refining petroleum and treated to recover part of the hydrocarbons, is concentrated by blowing hot air through it to a point somewhat below the concentration, near 57‹ BaumÚ, at which foaming and charring of the hydrocarbons take place. The bulk of the hydrocarbons are driven off by this treatment and the acid is further concentrated in the second apparatus. The first concentration takes place in a chamber A of acid-resisting brick provided with perforated earthenware pipes 17 through which hot air can be blown. The acid enters through a tower 18, in which it is preheated by the escaping fumes, and which may be packed or not as desired. The partly concentrated acid, freed from the hydrocarbons, passes to an " acid egg " C, and thence to a second chamber B like the chamber A, and provided with a preheating entrance tower 27.

Title: Improvements in or relating to the distillation of solid carbonaceous materials
IPC: C10J1/207
Filed: 1926-12-04
Abstract: 292,060. Nielsen, H., and Laing, B. Dec. 4, 1926. Divided on 276,407. Coking and carbonizing processes.-A process of distilling carbonaceous materials of a coking character consists in subjecting them to the action of hot gases containing a controlled percentage of oxygen (2 to 8 per cent) or an oxidizing constituent, so as to oxidize some of their coking constituents and influence their coking power, and, after carbonization gasifying the solid residue in the presence of steam. The carbonizing step of the process is carried out at temperatures not above 600‹ C. but may be followed by a high temperature treatment up to 1200‹ C. to reduce the volatile content to from 1 to 4 per cent. The carbonization may be carried out so that for any given size of material or thickness of fuel bed the period of distillation is so controlled that a temperature difference exceeding 100 to 150‹ C. is not allowed to exist between the temperatures at the centre and periphery of the material. The volume of gas for distillation purposes may be of such volume that the vapour tension of the oil fractions present is lowered sufficiently to enable such oils to be liberated in vapour form at temperatures not exceeding 500‹ C., and the gas carrying the oil vapours may be cooled to 100‹ C. without the oils condensing. A free burning residue is obtained which is not coated with graphitic carbon and which is easily oxidized by the oxygen present in ores such as copper or iron oxides or by steam in a water gas producer. The stripped gas from the process may be employed as the heating medium. Specifications 162,459, 192,515, 207,623, 212,961, 223,302, 227,880, 243,857, 287,037 and 287,381 are referred to.

Convention date, May 13, 1929. [Class 98 (ii).] Relates to the tinting of the pictures on a combination kinematograph and sound-record film. According to the invention, to ensure that the edge of the tinted portion adjacent to the sound-record area is sharply defined, the marginal boundaries of the area to be tinted are moistened before the tint is filled in between these limits, by using a tint-applying roller having flanges which are close to the film, and arranging that the contacting portions of the film and roller move in opposite directions. In the apparatus described, the tint is applied by a roller 25 having raised portions or flanges 27 spaced apart, the directions of rotation of the roller 25, and of the adjacent film-driving roller 17 being as shown by the arrows. The roller 25 rotates more rapidly than the roller 17. The arrangement is such that the flanges 27, closely adjacent to the film, moisten the film in sharply defined lines before the main application of the tint to the portion of the film between these lines is effected by the body 28 of the roller. The roller 25 may, as shown, dip into a bath 26 containing the tint, or the tint may be supplied to the flanged roller by a roller below it passing through the bath. Fig. 3 shows a modified arrangement for applying tint to two clearly defined areas between which an untinted space S is left on which the sound record lies. For this purpose, the roller 25 has four flanges 27 and a groove 32. The roller 25 may be directly beneath a film-feeding roller 17, or below a portion of the film stretched between two feed rollers. The apparatus shown in Fig. 1, comprises feed and take-up reels 9, 24, main rollers 15, 17, 18, 20, which are heated for rapidly drying the film after tinting, and a series of guide rollers 11, 21 and tensioning rollers 14, 22.
