Title: Improvements in or relating to the manufacture of cellulose derivatives
IPC: C08B3/28
Filed: 1939-05-12
Abstract: 531,955. Cellulose derivatives. BRITISH CELANESE, Ltd. May 12, 1939. No. 17664/40. Convention date, May 13, 1938. Divided out of 528,674. [Class 2 (ii)] A solution of a cellulose derivative in a solvent medium is passed continuously through a series of zones in which it is treated with precipitating liquid. In an early zone of the series precipitating liquid is added continuously to the solution to reduce the solvent power of the solvent medium and in at least one later zone further precipitating liquid is added continuously so as to complete the precipitation of the cellulose derivative. The solution and the precipitating liquid are subjected to a mixing operation during their passage through the zones, Separate sources of supply of precipitating liquid may be used to allow liquid of different concentrations to be used in different zones. As shown in Fig. 2, the solution of cellulose derivative is fed from a receiving vessel through a pipe 4 to a precipitating apparatus 5. A valve may be inserted in the pipe 4 to control the rate of feed. The precipitator comprises a casing 7 with windows 9. It is divided into several compartments. The first compartment 11 contains troughs 17, 18 with stirrers 19, 21 of the kind shown in Fig. 4. The second compartment 12 is similar to the first. The stirrers rotate in opposite directions so that the solution is forced upwards between them. Vessel 13 contains two troughs one of which has s stirrer of the kind shown in Fig. 5 while the other has a stirrer of the kind shown in Fig. 6. Vessel 14 is similar to vessel 13. Vessels 15, 16 contain troughs 35, 37, with stirrers 36, 38 of the kind shown in Fig. 6. The stirrers in each vessel have separate drives. Vessel 16 communicates through opening 45 with a sluiceway which directs the mixture issuing from this vessel into a settling tank from which the cellulose derivative can be drawn off into stabilizing baths or washers. Precipitating liquid is introduced into vessels 11-14 by means of feed-pipes (not shown) from a single source or from separate sources of supply. The solution of cellulose derivative may be diluted in vessel 11 with a 30 per cent. solution of acetic acid, and may be further diluted in vessel 12 with a 20 per cent. solution of acetic acid. The cellulose acetate may be precipitated in vessel 13 by the addition of a 10 per cent. solution of acetic acid, and a further quantity of this liquid may be added in vessel 14. Finally the mixture may be discharged as a fibre suspended in a 40 per cent. acetic acid solution. If desired the precipitating liquid used throughout the apparatus may be a 10 per cent. solution of acetic acid. Sodium carbonate may be introduced into vessel 11 or 12 to neutralize any inorganic acid catalyst and to produce a gas which tends to make the precipitate more voluminous. The process is applicable to acetylation or other solutions of cellulose acetate. It is also applicable to solutions of other cellulose esters or ethers.

Title: Improvements in sand ramming machines for filling foundry moulding boxes
IPC: B22C15/20
Filed: 1952-07-15
Abstract: 740,695. Moulding-machines. BEECH, A. S., and FOUNDRY EQUIPMENT, Ltd. July 14, 1953 [July 15, 1952], No. 17896/52. Class 83 (1). A foundry sand-ramming machine has a ramming assembly comprising a movable support, a ramming head, a ramming-head motor and a gear box in the drive between the motor and the head and mounted on the support, the support being movable to bring the head over any desired part of a mould, a hopper, deliveryregulating means for the hopper to vary the rate of delivery of moulding sand therefrom, means to convey sand from the hopper-delivery to the ramming head, gear change means for the gear box, and means for automatically altering the delivery-regulating means to correspond with the setting of the gear-change means. The machine is in most respects similar to that described in Specification 714,063, which is referred to, but a two-speed gear box 94 is placed in the drive from the ramming-head motor 89 to the ramming head 90, the conveyer 91 being driven from the output side of the gear box. The delivery-regulating means on the hopper comprises a sliding gate 81 which is operated by two air cylinders 130, 230, in tandem, the cylinder 130 being fixed to the hopper framing and the cylinder 230 moving with the gate. The gate and gear box are operated by pneumatic speed-control and gate-control buttons 116, 117, 217 on the head 90, each button actuating a valve 244, 245, 246 respectively. The highspeed button 116 causes the gear-change actuating cylinder 150 to change the gear box to its high-speed position and also partially closes the gate 81. Operation of the low-speed button 117 changes the gear box to its low-speed position and also opens the gate 81 to increase the supply of sand. The motor 89 is therefore fully loaded at both low and high speeds. The push button 217 functions to lower the gate and reduce the sand supply irrespective of whether the motor is operating at high or low speed, in order that the machine may run on a reduced sand supply for filling-in corners of moulds &c. The gear box may have three or four speedratios. Specification 714,064 also is referred to.
