Title: Production of unsaturated esters
IPC: B01J31/04
Filed: 1962-06-29
Abstract: In a process for the production of unsaturated esters by the catalytic vapour phase reaction of acetylene, methyl acetylene or propadiene with a saturated aliphatic monocarboxylic acid having from 1 to 7 carbon atoms or with benzoic acid, the activity of the catalyst is maintained during a shut-down in operation which occurs before the catalyst is spent by purging the catalyst with a gas which does not destroy the activity of the catalyst, the purging being commenced substantially immediately after the beginning of the shut-down period and being continued either for the duration of the shut-down or, if the duration is longer than one half-hour, for at least the first half-hour thereof. The purging gas may be an inert gas, such as nitrogen or carbon dioxide, or other nondestructive gas such as methane or the hydrocarbon reactant gas being used in the process. When purging is discontinued before the end of the shut-down, a blanket of the purging gas is preferably maintained in contact with the catalyst until operation of the process is resumed. The catalyst may be any conventional catalyst for a process of the above type, several such catalysts being specified.  Examples are given. Specification 581,501 is referred to.

Abstract: <PICT:0688781/IV (a)/1> <PICT:0688781/IV (a)/2> <PICT:0688781/IV (a)/3> <PICT:0688781/IV (a)/4> Cellulose organic ester filamentary textil materials, e.g. filaments, yarns, tow and ribbon, of improved tenacity, are produced by extruding a solution of the cellulose ester, e.g. a solution of cellulose acetate, propionate, butyrate, acetatepropionate or acetate-butyrate in acetone, ethylene chloride or a mixture of methylene chloride and ethyl alcohol or of chloroform and methyl or ethyl alcohol, and setting the shaped material in such a way that it contains substantially more than 1 per cent of its weight of solvent, then reducing the solvent-content to less than 1 per cent by weight, by passing a fluid capable of removing the solvent and inert with respect to the cellulose derivative through a loose mass of the material, and finally stretching the so-treated material.  The fluid may be air or other gas or a liquid miscible with the solvent and may contain a small proportion of the solvent. Following the stretching operation, the materials may be saponified, e.g. with aqueous sodium hydroxide, sodium carbonate or ammonium hydroxide.  A tow of stretched material may be breaker-drafted to produce a sliver of staple fibres, the sliver twisted to a roving and the roving saponified as described in Specification 667,147.  As applied to cellulose acetate threads, the thread is collected from the spinning cell in a sliver-can 14 (Fig. 6) provided with a perforated base.  The filled cans are then mounted on a chamber 18 (Fig. 2) provided with a perforated upper wall 21, and air is drawn through the can by connection of conduit 23 to an exhaustion solvent recovery system.  The threads are then withdrawn from the cans (Fig. 3) and passed through a stretching chamber 26, which may be of the type described in Specification 570,588, and contains steam under elevated temperature and pressure.  The threads are again collected in sliver-cans 14 and the filled cans mounted between caps 32, 33 (Fig. 4).  Saponifying liquid, e.g. aqueous sodium hydroxide containing sodium acetate at 60 DEG  C., from a tank 37, is forced upwardly through the cans by a pump 36.  The material is then washed with water introduced at 49 and discharged at 52.  Finally, drying is effected by drawing air through the mass in the cans.

Patent GB-1103091-A (GB)
Title: Improvements in or relating to tobacco smoke filters
Inventor: DAVENPORT FRANCIS ROBERT
IPC: A24D3/02
Filed: 1963-06-27
Abstract: 1,103,091. Tobacco smoke filters. CIGARETTE COMPONENTS Ltd. 29 June, 1964 [27 June, 1963; 8 Oct., 1963; 4 Dec., 1963; 7 Feb., 1964], Nos. 25661/63, 39681/63, 47963/63 and 5356/64. Heading A2C. A method of manufacturing tobacco smoke filters comprises the steps of applying to separated zones on a continuously fed web, tow or yam an additional filtering material in particulate, liquid or suspended state, forming the web, tow or yarn into a rod-like body with the zones of additional material in axially separated sections and cutting the rod-like body transversely into filters. As shown in Fig. 1 paper from a roll 1 is led between an applicator roll 7 and presser roll 8. The roll 7 has surfaces 12 which contact a roller 9 rotating in a trough 11 filled with a slurry of carbon. The web is thereby transversely coated at intervals, passes under a heater 13 to a plug making device 3, and is cut into filters 5. If crepe paper is to be coated the roll 7 is replaced by a roller having raised circumferential portions so that the coating is applied parallel to the direction of feed of the web. The web is then cut transversely and formed into plugs having a longitudinal exit parallel to the transverse cuts (Figs. 4 and 5, not shown). Instead of paper, filamentary material may be used to which a plasticiser e.g. triacetin or sodium carboxymethyl cellulose is applied before closing with the additional material. The applicator may be in the form of a reciprocating nozzle 71 (Fig. 11). The additional material is fed through a connection 72 and connects between the body 70 and needle 83. The body 70 is reciprocated in a guide 75 by cams 79 on a shaft 80 and a cam 81 controls the needle 83. The arrangement is such that the needle 83 is lifted in relation to the body 70 at the time the application of material is to be made so that the additional material can flow through the nozzle 71. If the additional material is in solid form, e.g. activated carbon mixed with a fine resin, the roller 111 (Fig. 16) may be used. This roller rotates under the hopper filled with the additional material and has grooves 113 for receiving the material. The web contacts the roller 111 and the material is deposited thereon, the web being then heated to fuse the resin. The heating may be effected by injecting steam into the web whilst it is being formed into a rod. Instead of carbon, other additional materials such as liquid polyethylene glycol, sepiolite and fullers earth may be used.

Filed: 1948-10-08
Abstract: 656,125. Phase difference measuring circuits. DECCA RECORD CO., Ltd., O'BRIEN, W. J., BRIDGES, D. E., HENDLEY, D. A., EASY, M. H., and VICKERS, J. Oct. 8, 1948, No. '25732/49. Divided out of 656,108, [Group XL (c)] [Class 37] [Also in Group XL (c)] A phase discriminator is arranged to give a steady output voltage unless the phase difference between the input signals is within certain narrow limits. The discriminator is used in association with a fine control discriminator of normal cosine output type to control a crystal oscillator (see Group XL (c)). The arrangement is of particular use in maintaining a slave station oscillator in synchronism with the master transmission in a navigation system such as described in Specification 656,108. The reference phase signals are fed to T37, outputs in phase quadrature being derived over connections 16 and 17 while the oscillator output is fed to T44. Diodes V43 combine the inputs signals to produce an output proportional to the sine of the phase difference on diode V20. The outputs of diodes V44 and V45 also combining the input signals are applied to diodes V21 and V22 and are respectively proportional to minus the sine and the cosine of the phase difference. The output of diodes V20, V21 and V22 are combined to produce on the control grid of triode V48 a potential equal to the highest positive volts produced by the diode comparison pairs. Triode V48 is connected as a cathode follower and its output is fed through a circuit including diode V23 which has a long time constant for charging and a short one for discharge to a second cathode follower V49. The output of this circuit derived as T is a substantially steady potential signal over a wide range of phase variations dropping from full strength at small variations to either side of phase equality to zero at zero phase difference (Fig. 2, not shown). The output of the discriminator is used to control diodes V5 switching condenser 14 out of circuit to drift the oscillator to the correct phase relationships with the standard. The second phase discriminator shown in the left bottom corner of the Figure produces a fine control potential applied across the crystal 10 of the oscillator through contacts P, Q. During breaks in the reference signal relay contacts 62 and 63 open and storage condensers 64 and 65 maintain control.

Abstract: 1314445 Fertilizer compacts DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 29 May 1970 [31 May 1969] 25980/70 Heading C1B A process for producing fertilizer compacts comprises converting oxamide or a fertilizer composition containing oxamide into compacts, at least one NH- group-containing compound which is able to form a polymeric condensate with formaldehyde and at least one formaldehyde.yielding substance being added as solids either before or during conversion into compacts. Conversion into compacts may be by tabletting, extrusion or by granulation on a plate or in a drum. Suitable NH- groupcontaining compounds are urea, alkyl-, phenyl-, acetyl-, cyclic- or polymeric-ureas, urethanes, thioureas, cyanamide, dicyanamide, guanidines, aminotriazines, polyalkylene amines and ammonium cyanate. The formaldehyde-yielding substance may be paraformaldehyde, hexamethylene tetramine or granuform. The oxamide may be mixed with Thomas meal, superphosphate, potassium sulphate or quick-acting nitrogen fertilizers such as potassium nitrate or calcium nitrate. The compacts which are formed in this process are uniformly penetrated by a solid skeleton structure of a urea-formaldehyde condensate which leads to high compressive strength and abrasion resistance. However, the skeleton structure forms such a fine layer that it readily disintegrates under the influence of the soil. The urea : formaldehyde ratio may range from 2 : 1 to 1 : 10. If highly hygroscopic constituents are present, e.g. calcium nitrate, high disperse silica or active carbon may be added before or during compacting, in order to improve the free-flow properties of the material.

Abstract: 783,432. Fluid-actuated valves. LEEDS METER CO., Ltd. Oct. 31, 1955 [Sept. 9, 1954], No. 26096/54. Class 135. Valve mechanism for use with a combination meter for measuring liquid flow comprises a main valve member 8 hinged at 7 and connected by a link 11 and lever 12 with a by-pass valve member 4 of self-closing butterfly type. The inlet 5 to the valve housing leads from a main meter whilst an inlet 3 controlled by the valve member 4 leads from a low-range meter. The lever 12 carries a weight 14 which normally causes the main valve member 8 to be seated and the butterfly valve member 4 to be held open by an abutment 16. When the rate of liquid flow exceeds a certain amount the pressure difference across the main valve member overcomes the loading of the lever 12. Due to the connection of the main valve member to the lever 12 being near the pivot 13 and that of the butterfly valve member 4 remote from the pivot the valve member 4 will close rapidly in relation to movement of the main valve member.
