Title: Improvements in and relating to the production of water-soluble cyanoethyl ethers of cellulose
IPC: C08B11/155
Filed: 1948-02-10
Abstract: A water-soluble cyanoethyl ether of cellulose is obtained by subjecting viscose to the action of about 0.5 to 1.2 mols of acrylonitrile per anhydroglucose unit of the cellulose in the viscose at a temperature not greater than 40 DEG  C., separating the water-insoluble cyanoethyl ether of cellulose so produced from the reaction mixture, dissolving or suspending the separated ether in dilute aqueous alkali solution, and reacting the solution or suspension with 0.1 to 3 mols. of acrylonitrile per anhydroglucose unit originally present in the cellulose.  The second stage of the cyanoethylation may be effected by dissolving the water-insoluble first stage ether in a 2-4 per cent aqueous caustic soda solution and reacting the solution with acrylonitrile for 0.25 to 3 hours, or by suspending the swollen first stage ether in a 0.7-1.2 per cent caustic soda solution and reacting the suspension with acrylonitrile for 3 to 5 hours, the temperature in both cases preferably being maintained between 5 DEG  and 30 DEG  C.  In examples, water-soluble cellulose ethers containing 0.71, 0.55, and 0.8 cyano-ethyl groups per anhydroglucose unit of the cellulose are obtained.  The viscose employed contains 7.75 per cent of cellulose and 6.2 per cent of caustic soda and has a salt index of 5.5.  The water-insoluble ether produced in the first stage is separated from the alkali solution by diluting the solution with water and then adding it with stirring to a slight excess of dilute hydrochloric acid.  The first-stage ether may be swollen in water and then dissolved to form a 5 per cent solution in a 2 per cent caustic soda solution, or it may be suspended in a more dilute caustic soda solution.  Treatment with the acrylonitrile may be facilitated by stirring or shaking.  The reaction solution is neutralized with dilute hydrochloric acid and may then be dialyzed and concentrated under reduced pressure to form a paste.  The ether may be precipitated by the addition of alcohol.

Abstract: 578,420. Etectric signalling systems. ROST, H. F., THUNELL, K. H., VIGREN, S. D., and CLAESSON, P. H. E. Nov. 24, 1942. No. 3852/44. Divided out of 578,406, [Group XL]. [Class 40 (i)] [Also in Groups XXXVI and XL] A circuit arrangement for continuously measuring a varying frequency, e.g., for use in radiolocation systems of the frequency-sweep type, comprises a wave-analyser with a variable-frequency local-oscillator automatically set by a coarse adjustment so that when the local oscillations are mixed with the oscillations to be measured they produce a beat frequency within the band to which an intermediate frequency amplifier is tuned, the latter being associated with two resonant circuits tuned to adjacent frequencies from which voltages are derived to control the local-oscillator tuning means to effect a fine adjustment of the frequency. The driving means for adjusting the local-oscillator frequency is provided with an indicator which continuously shows the frequency to be measured or the distance of a reflecting object. As shown, the output voltage V1 of a direct-reading frequency meter 51 is combined with the voltage V2 across a potentiometer 52 to control a relay R10 connecting up the driving motor 59 and a polarized relay R8 which determines the direction of rotation. Motor 59 rotates potentiometer 52 and a condenser 62 in the local-oscillator of the wave-analyser 63 until voltages V1, V2 are equal when relays R8, R10 release. The control of motor 59 is then switched over for fine adjustment to a polarized relay R9 controlled by the resonant circuits associated with the intermediate frequency amplifier. Counter 66 on the motor shaft gives a reading of the frequency or, in a radio-location system, of the range.

[Class 39(ii)] [Also in Group XL(a)] The end of a tubular glass envelope 62, into which a closure meber 60 has been sealed by the drop sealing process, is moulded by a roller 43 pressed radially inwardly toward the axis of the envelope at and near the line of seal and while the glass is plastic to form a substantially cylindrical spigot 63 and a step between the spigot and the remainder of the envelope. A rotary machine for the process has supports 11 for a platform 10 with a bearing 12 for a hollow vertical spindle 13 which is driven with the keyed wheel 16 through the striker 17 and gears 20 by the motor 18. A spider 21 keyed to the spindle carries a ring of heads 22 each with a tubular stem 23 surrounding a shaft 29 which has gear boxes, 24 at the top and 25 at the bottom, to rotatably carry the cradle 26 holding the envelope 62 and the pin 28 for the stem 60, so that the envelope and stem are rotated in unison. The shaft 29 is rotated through the keyed pinion 30 by a gear wheel 31 which is integral with a worm wheel 33 which is driven by the worm 34 from the motor 37. A roller 43 on each head is mounted with its axis vertical, is slidable to and from the cradle axis in the guide 45, and is actuated through a link 46 bell crank lever 47 and roller 49 by a sector-shaped plate 59 on the top of a rod 50. The latter is linked at 53 to a pivoted cam follower lever 54, and is moved up and down as the lever is oscillated through the roller 57 by a shaped cam 56 driven by the gears 20. Levers 47, 54 are returned by springs 48, 58. Feet 39 on the heads run on rails 40, and burners 42 are mounted at the required stations. At successive stages the envelope 62 is heated so that it collapses on to the skirt 61 of the stem 60, then heated and rolled to form the cylindrical spigot 63 and step. A smooth roller and then the roller 43' with a patterned thread may be used, and the corrugations thus formed on the spigot increase the adhesion of the cement 66 when a cap 65 is fitted. The socket-shaped cap is located axially by the step. The length of the envelope is accurately controlled by this method.
