Title: Process and apparatus for the continuous manufacture of cellulose acetate
IPC: C08B17/02
Filed: 1927-04-06
Abstract: 274,814. Soc. Chimique des Usines du Rh¶ne. July 26, 1926, [Convention date]. Continuous-discharge apparatus with moving containers.-Cellulose acetate is made by passing the reagents continuously through apparatus of small diameter compared with its length and rotating about an inclined axis. The temperature at different zones may be regulated by sprinkling the outside of the apparatus with hot or cold water. The diameter of the apparatus may be variable so as to modify the speed of the travel of the reagents at different parts of the apparatus, and material may be caused to accumulate at desired points by arranging perforated discs or continuous or discontinuous helicoidal partitions in the apparatus, and near these points, energetic stirring may be affected by means of straight or bent rods arranged radially or at some distance from the wall and carried by the wall near the inlet end, and in the second part of the apparatus where the mass is of a pasty consistency paddles may be employed. Baffles may be provided independent of the wall and carried by a central shaft, and these may be inclined to the axis of the apparatus to assist in causing the reagents to travel. The rods and paddles may be carried by a central shaft instead of by the wall and a heating or cooling fluid may be circulated through the stirring devices. Several of the inclined rotary apparatus may be arranged in conjunction, part of the process being carried out in each; their inclinations and rates of rotation may be different, and fresh reagents may be added at the various stages of the operation. The apparatus may consist of a tapered cylinder 1 Fig. 1, rotating about a slightly inclined axis, with sprays 8 directed upon its outer surface. Reagents are admitted at 5, 6, and 7 and the finished product is withdrawn at 9. In a modification, Fig. 2, stirring rods 10, paddles 11 and 13 and helicoidal paddles 12 are carried by the wall of the reaction chamber, and a disc 16 with a central opening causes an accumulation of material at one point. Baffles 14 and 15 inside the shell are provided for ensuring a regular advance. of the reaction mass. Specifications 231,837, [Class 2 (ii), Cellulose &c.], and 270,656 are referred to.
Patent GB-857781-A (GB)
Title: Improved method and means for barrel finishing
Inventor: GOULDING HOWARD DUNCAN
IPC: B24B31/03
Filed: 1956-03-27
Abstract: 857,781. Tumbling. ROTO-FINISH Ltd. June 27, 1957 [March 27, 1956], No. 9520/56. Class 60. A method of finishing work-pieces by tumbling them together with polishing materials in a barrel 1 comprises rotating the barrel about a horizontal or approximately horizontal axis, continually feeding the polishing material and work-pieces into an inlet aperture 8, and discharging them continually through an outlet aperture 10 having its lower edge at a lower level than the lower edge of the inlet such that the difference in level causes the progression of the contents through the barrel. If desired, periods of continuous introduction and discharge are alternated with periods during which no fresh material is introduced and discharge is prevented, tumbling being continued without substantial axial movement of the material in the barrel. As shown, the inlet and outlet apertures 8, 10 are provided in rigid end walls 7, 9 attached to the barrel and are in the form of circular holes concentric with the axis, the outlet aperture being larger in diameter in order to obtain the difference in level between the lower edges of the apertures. The difference in level may be varied by changing the apertured end walls or by partially blanking off one of the apertures. Alternatively, either or both of the openings could be formed by an aperture in a stationary end plate which is in sealing engagement with the rotating drum, the level of the lower edge of the opening then being adjusted by altering the height of the plate. In another arrangement, the rigid end wall of the drum may be in the form of a resilient diaphragm having a central aperture bounded by a collar engaging with a non-rotating locating member which may be adjusted in order to stretch the diaphragm and thereby alter the level of the aperture ; such an arrangement may be replaced by an iris-type diaphragm which can be adjusted during rotation of the barrel. In operation, polishing material, such as rock fragments and an abrasive, either dry or included in a liquid, may be initially introduced through a shoot 11 and distributed along the length of the dum by rotating the latter at high speed ; this is followed by the introduction of the workpieces and move tumbling media for the finishing operation proper. Discharge occurs through a shoot 12 at a rate dependent upon the setting of the outlet aperture 10. To increase the treatment time, the feed is stopped at intervals and the discharge prevented by either closing the outlet aperture or, aligning its lower edge with that of the inlet, thus preventing any progression of the workpieces during the continued rotation of the barrel. Alternatively, the feed may be interrupted and the level allowed to fall to that determined by the discharge aperture. The barrel is rotated by an electric motor 5 driving through a pinion a toothed ring 6 secured to the barrel which is supported on rollers 3 mounted on a base 4.

Title: Improvements in and relating to the production of olefine oxides and carboxylic acids
Inventor: COFFEY ROBERT STEVENSON
IPC: C07C51/235
Filed: 1961-03-17
Abstract: Oxygen containing compounds comprising olefine oxides and carboxylic acids are produced by contacting a liquid mixture containing an aldehyde of 2 or more carbon atoms and an olefinic compound having a terminal double bond and containing 3 or more carbon atoms with a gas containing molecular oxygen at 40 to 150 DEG C. Acetaldehyde is particularly suitable but higher straight and branched chain aliphatic and aromatic aldehydes may be used. The olefines may be aliphatic mono-olefines, those with an alkyl group or the 2-carbon atom being preferred, and may contain other functional groups, e.g. hydroxy, alkoxy, keto, carboxyl, esto, aryl and halide. Di-olefines, e.g. butadiene, may also be used and yield mono and/or di-oxides.  As oxygen-containing gas, oxygen itself, mixtures of oxygen and nitrogen or oxygen with any suitable diluent, e.g. CO2 or the olefine to be oxidized, may be used. The reaction, which may be performed batchwise, semi-continuously or continuously in the presence or absence of a diluent, is preferably initiated by, for example, U.V. light, various peroxide compounds and/or inorganic or organic salts of variable valency metals.  The material of construction of the apparatus is of importance, porcelain, glass, enamel, resins, aluminium, tin and, in particular, "Staybright" (Registered Trade Mark) metal being suitable, and the volume: surface area ratio thereof should be as large as possible. The Provisional Specification relates to the co-oxidation of aldehydes and non-terminal olefines as well as the process of the invention.
