Title: Process for enhancing the fastness to washing of flame-resistant dressings on textiles
IPC: D06M15/433
Filed: 1954-08-03
Abstract: 772,367. Fireproofing textile materials. CIBA Ltd. Aug. 3, 1954 [Aug. 4, 1953], No. 22525/54. Class 140. Textile material which has been rendered flame-proof by the process disclosed in Specification 747,014, [Group IV (c)], is further treated with formaldehyde to enhance the fastness to washing of the flame-resistant dressing. The treatment may be carried out at 80-150‹ C. using an aqueous solution of formaldehyde. Gaseous formaldehyde, or compounds yielding formaldehyde such as para-formaldehyde or hexamethylene tetramine may also. be used. The formaldehyde solution may contain a small amount of a hardening catalyst. Examples describe treating with formaldehyde a cotton fabric which has been rendered flame-proof in the manner referred to. The fabric may be immersed in a bath at 90 ‹ C. containing water, formaldehyde and ammonium chloride; or it may be immersed in a cold bath containing water and formaldehyde followed by pressing and drying at 90‹ C.; or it may be steamed wet in the presence of formaldehyde at 120-130‹ C. under 1 atmosphere gauge pressure. If the fabric which has been treated with formaldehyde is subjected to alkaline washing (e.g. with soap and soda) it must subsequently be subjected to ion-exchange treatment, e.g. by immersion in a bath containing salts such as ammonium sulphate, chloride, carbonate, nitrate, diammonium phosphate or ethylene dihydrochloride, in order to restore the flame-resistant properties.

Title: Improvements in or relating to seals for rotary shafts
Inventor: BIRNIE GEORGE ROBERTSON
IPC: F16J15/42
Filed: 1958-07-17
Abstract: 848,601. Stuffing-box substitutes. DAVIDSON & CO. Ltd. June 2, 1959 [July 17, 1958], No. 23024/58. Class 122 (5). A centrifugal liquid seal for the shaft 11 of a fan, compressor or like device 14 for producing fluid pressure in a casing 13 comprises a rotor 15 mounted rotatably on the shaft and having an annular channel opening radially inwards, first and second annular flanges 22 and 24 rigidly secured to the shaft and the casing respectively and both projecting into the channel 19, and means for supplying liquid 27 to the channel. The rotor 15 is mounted on a bearing 16 and may be driven by any suitable means, for example an electric motor, but is preferably rotated by compressed air or other pressure fluid ejected through nozzles 26 on to vanes 25 on the rotor. The compressed air is supplied to the nozzles 26 through a pipe 29 from a reservoir 30 supplied by a compressor 31 (Fig. 2). Rotation of the rotor causes an annular well of sealing liquid 27 to be formed by centrifugal action in the channel 19 into which well the peripheries of flanges 22 and 24 dip to provide a seal. If the fluid in the casing 13 is a liquid, part of it may be utilized as the sealing liquid 27 but, preferably and when the fluid is a gas, the sealing liquid is supplied to the channel 19 from a container 32 via a pipe 33, valve 34 and passage 35 in a protuberance 36 on an element 23 integral with the flange 24 and circulated through a passage 42 in the flange 24 and a passage 39 in a further protuberance 38 on the element 23 communicating by a pipe 40 and metering valve 41 with the container. The sealing liquid in the container is cooled by passing the compressed air through a coil 45 therein. If it is desired to maintain the pressure in the casing 13 during a temporary stoppage, the rotor 15 is kept running with the shaft at rest. When the machine is shut down the channel 19 may be emptied, after the pressure in the casing 13 has been removed, by continuing to rotate the rotor, closing the valve 34 and fully opening the valve 41. A maintenance seal may be provided comprising sealing faces on the casing 13 and on the device 14 which faces mutually engage when the shaft is moved axially.

Title: Improvements in or relating to the purification of low-pressure polyolefins
Inventor: REAY WALTER HARKNESS
IPC: C08F6/24
Filed: 1959-07-06
Abstract: <PICT:0879142/III/1> <PICT:0879142/III/2> A Ziegler-polymerization slurry of polyolefin, in a light petroleum distillate containing also components of a Ziegler-type catalyst is removed, continuously or intermittently, from reactor 3 and fed through a line 4 to one end of an elongated vessel 5 fitted with a rotatable screw 6 for moving the polymer through the vessel towards an outlet pipe 7.  Ethanol or a mixture of ethanol and a light petroleum distillate is fed to the line 4 through a line 9.  The vessel 5 with heat-transfer jacket 20 has partitions 10 fixed to a removable top-part 11 of the vessel 5, disposed vertically in spaced apart relationship so that their lower ends 10a fit loosely round the screw 6, and so form compartments 12 each opening out at the bottom, i.e. in the region of the screw 6, into a longitudinal polymer-treating zone 51 formed by the lower part of the vessel 5 which houses the screw 6.  Each compartment 12 is connected to a header 14 loading a condenser 16 from which condensate is returned to the exit end of the vessel 5, valved lines 18 and 19 being provided to enable the condensate to be returned either to the exit and adjacent the outlet pipe 7 or to a point further along the vessel 5.  The polyolefin slurry removed, at the end of the treatment, via line 7 is conveniently centrifuged to remove supernatant solvent and the resulting solvent-wet polymer then passed to a steam-stripping stage for further treatment e.g. as described in Specification 801,554 and thereafter processed in a devolatilising extruder to give a purified polymer.  Specifications 798,912, 799,392, 799,823, 801,031, 810,023, 819,867 and 820,263 also are referred to.

Title: Improvements in and relating to electric speed and frequency indicators
IPC: G01R23/02
Filed: 1931-08-18
Abstract: 377,458. Electric and magnetic speed indicators. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rohner, A. J. ; 6, Jackson Place, Schenectady, New York, U.S.A.) Aug. 18, 1931, No. 23254. Convention date, Aug. 18, 1930. [Class 106 (iii).] A speed or frequency meter includes a transformer which is so arranged that the secondary voltage is proportional to the frequency of the primary current independently of changes in the voltage applied to the primary winding. A speed indicator for aircraft engines comprises a magneto generator consisting of a stator 12 with windings 11 and a permanent magnet 14, having pole-pieces 15, driven by the aircraft engine. The winding 11 is connected to the primary winding 25 of a transformer formed from T-shaped stampings arranged to form parallel legs 17, 18 connected by the central leg 19 on which the primary winding 25 is wound. Corresponding ends of the legs 17, 18 are connected by a laminated leg having a restricted section 22 and wide end portions 23 to ensure good magnetic contact with the legs 17, 18. A secondary winding 26 surrounds the restricted section 22, a similar winding 27 being arranged between the opposite ends of the legs 17, 18. The secondary windings 26, 27 are connected in opposition and in series with a full-wave copper oxide rectifier, by means of which the secondary current is rectified and measured by a millivoltmeter 38. The magnetic flux divides into two branches threading the windings 26, 27, respectively. The reduced iron section 22 becomes saturated during a part of each cycle, so that the difference between the maximum fluxes threading the coils 26, 27 is constant independently of changes in the voltage applied to the primary coil 25 caused, for example, by changes in the strength of the magnet 14. The resultant voltage of the windings 26, 27, is consequently directly proportional to the frequency of the current supplied to the winding 25, i.e. to the speed of the magnet 14. A high resistance 37 having a zero or slight negative temperature coefficient is connected in series with the windings 26, 27, and the instrument 38 is shunted by a resistance 39 of zero or slight negative temperature coefficient, in order to compensate for temperature errors. The permanent magnet 14 may be of cobalt steel, and the laminations of the transformer may be of permalloy. The winding 27 may be held in position by the same means which secure the transformer in place, or it may surround a piece of wood, brass, or other non-magnetic material secured to the ends of the legs 17, 18. Either or both of the coils 26, 27 may surround the corresponding part of one of the legs 17, 18.

Title: Improved means for measuring out pre-determined quantities of liquid from glass bottles and the like
IPC: G01F11/26
Filed: 1935-08-20
Abstract: 451,893. Delivering measured quantities of liquids. KEAY, R. W., 3, Southend Road, Beckenham, Kent. Aug. 20, 1935, Nos. 23312/35 and 1869/36. [Class 106 (v)] Apparatus for delivering measured quantities of liquid from a bottle comprises a measuring chamber adapted to be attached to the neck of the bottle so that when the bottle is inverted liquid passes through a tube B into the measuring chamber and when the bottle is returned to normal position the liquid is retained in the chamber by the action of an automatically operating non-return valve D, the measured quantity being subsequently discharged through an outlet tube G projecting laterally from the bottom of the chamber and controlled by a valve K adapted to be opened manually against the action of a spring L, The outlet tube G contains an air vent pipe H also controlled by the valve K. The measuring chamber comprises a hollow metal base A to the top of which an inverted glass cup N is clamped by a protecting cap P screwed on to the base A. A cross-bar E at the upper part of the base forms a guide for the pin of the non-return valve D and as a result of friction between the pin and the guide when the bottle is in an approximately horizontal position, if the bottle is rotated to its normal position slowly, the valve remains open for a time sufficient for the contents of the measuring chamber to flow back into the bottle.

Title: Improved flow control apparatus
Inventor: BENNETT HENRY WILLIAM
IPC: G05D7/00
Filed: 1955-08-12
Abstract: 804,543. Flow-spreaders for paper-pulp etc.; air-felting machines. KIMBERLY-CLARK CORPORATION Aug. 12, 1955, No. 23345/55 Class 96. Apparatus for controlling the flow of fluids in paper-making machines comprises a flowspreader 33, Fig. 1, into which a stream of fluid, e.g. aqueous paper pulp, is fed through a conduit 31. The flow-spreader has two diverging walls in one or both of which are one or more slots 37 through which a controlled amount of fluid can pass to increase the average kinetic energy of one or both boundary layers of the spreading stream and thus prevent separation of the boundary layer or layers from the main stream and formation of vortices. A conduit 35 conveys the fluid from the flow-spreader to the paper-making machine. Fluid may be removed through the slots by a suction pump 39 acting through a conduit 45, manifolds 43 and valves 47. When the pressure of fluid in the flow-spreader is sufficiently high, fluid can be discharged through the slots without applying suction. Alternatively, fluid may be fed into the flow-spreader through the slots. The upstream edge of each slot may be rounded and the downstream edge may be dulled. The width of each slot may be one-quarter to four times the width of the adjacent boundary layer. Each slot may extend for at least three-quarters of the height of the wall in which it is located and outwardly from it for a distance at least twice the width of the slot. A plurality of flowcontrol members separated by equi-angular spaces may be disposed within the flow-spreader to give substantially uniform flow of fluid across the stream issuing from the flow-spreader. These members may be vanes as described in Specification 733,851 or rotatable circular rods. In an air-felting machine, Fig. 16, a bat 145 of natural or synthetic fibres is fed by a roller 149 to a picking roller 147 rotating in a chamber 151. Fibres 153 removed from the bat are directed on to an endless travelling forming wire 155 by air, which enters the chamber through openings 159 and 161. Air is blown into the machine through a duct 171 and passes, through conduits 173, flow-spreaders 177 and conduits 189, into the chamber 151. Each flow-spreader is rectangular in cross-section and increases uniformly in width until it achieves the width of the chamber. Each flow-spreader is provided with slots 179 connected, through valves 187 and conduits 181 to a main conduit 183 leading to a suction fan 185. Flow-control vanes may be provided in the flow-spreader. The fibres form a loose web 167 which is compressed and rendered selfsupporting by rubber-covered rollers 169. Air is drawn off into a suction-box 163.
