Title: Improvements in or relating to a process of sulphation
IPC: C07C305/10
Filed: 1949-02-28
Abstract: A process of sulphonation of an aliphatic hydroxy compound comprises mixing a stream of liquid sulphur dioxide containing dissolved sulphur trioxide with a stream of liquid sulphur dioxide containing a dissolved aliphatic compound having at least one hydroxy group, flowing the mixed streams through a nozzle and evaporating the liquid sulphur dioxide by means of the heat of sulphation whereby the sulphur trioxide combines with the hydroxy compound at a temperature of at least 20 DEG  C.  Suitable hydroxy compounds are methyl, ethyl, propyl, butyl, secondary isobutyl, hexyl, octyl, 2-ethylhexyl, decyl, lauryl, tetradecyl and octadecyl alcohols, ethylene glycol, polyethylene glycol, glycol p  or polyglycol esters of fatty acids and the corresponding ethers of aliphatic alcohols.  In the Figure, 1 is a tank containing a sulphur dioxide solution of sulphur trioxide, tank 2 contains liquid sulphur dioxide and tank 3 contains the alcohol to be sulphated.  Tanks 1, 2 and 3 are supported on scales 4, 5 and 6 so that their contents may be weighed.  Tanks 1 and 2 are provided with pressure gauges 7 and 8, <PICT:0676690/IV (b)/1> respectively, and with connections 9 and 10 for introducing liquid sulphur dioxide from pipe 11.  Tanks 1, 2 and 3 are provided with bottom outlets and valves 12, 13 and 14, respectively, for controlling the flow of their contents into pipes 15, 16 and 17. The liquid sulphur dioxide containing dissolved sulphur trioxide, flowing through pipe 15 passes through flow-meter 18, then through pipe 19 and enters mixing nozzle 20.  The flow of liquid sulphur dioxide in pipe 16 passes through flow-meter 21 into pipe 22.  The alcohol in tank 3 flows by means of pipe 17 into pump 39 whereby it is forced through pipe 23 into flow-meter 24 and into pipe 25. The liquids flowing into pipes 22 and 25 are combined in pipe 26 in which the alcohol dissolves in liquid sulphur dioxide.  Nozzle 20 is contained within chamber 27 which may be provided with a packed section 28 of Raschig rings or other suitable filtering material The chamber is closed by flanges 29 and 30.  An exit for the liquid sulphation product is provided at 31 and a gas exit at 32.  Pipe 33 connects with an additional liquid gas separator 34 which is provided with a liquid outlet 35 and a gas outlet 36. The sulphated product is withdrawn mainly by means of pipe 31 but a small amount is usually recoverable at the outlet of pipe 36. The vaporized SO2 leaving the gas separator 34 by means of pipe 36 may be compressed and liquefied and returned as liquid sulphur dioxide to pipe 11 for reuse.  A manometer 37 indicates the pressure in the collecting zone 27 and a thermocouple 38 is provided with its junction adjacent to nozzle 20 to indicate the temperature inside the nozzle.  In the examples: (a) decyl alcohol, (b) tetradecyl alcohol, (c) lauryl alcohol, (d) ethylene glycol, (e) ethyl alcohol, (f) glyceryl monolaurate are dissolved in liquid sulphur dioxide and sulphated by a solution of sulphur trioxide in sulphur dioxide.

The device A for breaking the supply circuit when the paper breaks comprises a spring- pressed lever 21, Fig. 2, which swings over when the paper b breaks and lifts a contact lever 23. The device for detecting a broken thread comprises a spring-pressed lever 24, Fig. 4, which swings over when the thread breaks and lifts a contact 28. A similar device is employed to detect a broken backing strip but the strip is passed round a roller on the other end of the lever. The devices are connected in series with the motor 20, Fig. 6. To start the machine a rotary switch 22 is turned in the direction of the arrow to make contact 54, 55 and close circuit 46, 46a, 47b, 47a, 47. The consequent energization of a magnet 58 closes a switch 53, 60 and completes the motor circuit 46, 49, 50. Rotations of the switch 22 makes contact 52, 54 and finally break contact 54, 55. Thus the motor circuit is dependent upon the energization of the magnet 58, the circuit of which includes the fault detecting devices. The device A is byepassed by a contact 40 which is opened periodically by a cam 4<1> to apply a test through the devices. To byepass the current after a book is completed a circuit 46c, which includes a contact 35 operated by a counting mechanism D, is provided.

Abstract: 1,178,972. Optical testing apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. Feb.8, 1967 [Feb. 10, 1966], No.5955/66. Heading G2J. In apparatus for testing the angular position of a reflecting surface R, white light from source S is passed through a wavefront inversion device I, reflected at surface R and returned through device I, the interference between light components which have suffered an odd number of wavefront inversions respectively in their outward and returns paths through device I being observed at E as an indication of the angular position of surface R. Device I comprises a cylindrical glass block with its longitudinal axis on OO' and having partially reflecting coated spherical end surfaces C, C' with a common focal plane within the block, and equal radii of curvature. Source S is at an external focal plane F of the device, and a beam splitting prism D diverts returning light to an image plane F' for observation. Images 1, and k are selected of which one is invented at surface R, whereby lateral misalignment of surface R from axis OO' may be corrected by bringing the images into coincidence. Tilting of the surface is corrected by observing the spacing of the straight fringes formed by interference between the rays forming images 1, h. Surface R is normal to axis OO' for infinite fringe spring. In a modification, a polariser is included in beam splitter D and a quarter-wave plate Q is placed between device I and surface R to eliminate unwanted reflections.

Abstract: 873,235. Cleaning textile spinning &c. machines. LUWA A. G. Feb. 20, 1959 [Feb. 20, 1958], No. 6029/59. Class 120(3) In a textile mill, each spinning frame is cleaned and heat produced by the individual driving motors thereof is dissipated by causing air streams to entrain broken ends, lint or fly and move through collecting headers, connected with a common main duct, to passages each housing one of the motors and, during movement of the streams through the passages, entraining therein air heated by the motors. As shown in Fig. 1 and Fig. 2 or 4, collector units 32 each comprising a door 73, intake orifices 74 and filter 76, are connected by ducts to housings 60, for motors 10 of frames F, which are connected by ducts 61 to a header 62 leading to a duct 63 incorporating a fan 64 and opening into a plenum chamber 65 which may contain refrigerating and/or humidifying apparatus. Outside air, relief, intake and discharge dampers 66, 67, 68 and 69 are controlled e.g. automatically, to vary the quantities of outside air and mill air in the air returned to the mill by a duct 70 and discharged through louvres 71. In a modification, Fig. 5, a collecting header 75 directs lint &c. to a central material recovery room (not shown) and at each motor 10 it forms a housing with a by-pass 36 and a screen 37 preventing passage of lint &c. therethrough. In the collector unit shown in Fig. 6, the main air stream is filtered by a screen 43 and a hood 45 permits the air heated by motor 10 to be drawn thereinto. In another embodiment, Fig. 7 (not shown) the motor is cooled by air flowing through an auxiliary intake duct connecting a motor hood with header 75. The header 75 may lead to a centrifugal-concentrator separator within the housing 60 and comprising solid, foraminous and tapered portions extending to a material handling duct which leads to the duct 61 of larger cross-section, Fig. 8 (not shown). The unit 32 may connect directly with duct 61 in which two curved plates deflect the air stream to and from housing 60, Fig. 9 (not shown).
