Filed: 1928-04-11
Abstract: 291,082. Hercules Powder Co., (Assignees of Milliken, M. G.). May 28, 1927, [Convention date]. Cellulose nitrates.-Cellulose to be nitrated is submerged in a stream of nitrating acid and then passed through a body of nitrating acid in which it. remains submerged until nitration to the desired degree is effected. As shown, cellulose, particularly cotton, is supplied through a hopper f to a perforated cylinder b supported in a casing a. Nitrating acid from a tank passes through a heater or cooler t and enters the hopper f by a nozzle o in amount sufficient to submerge the cotton, further amounts of acid being supplied to the cylinder b by pipes p. A worm c carries the submerged cotton through the cylinder b, and a continuous flow of acid through the casing a is maintained by a pump t, which draws acid through pipes r, s<1>, s, and delivers it to the tank j, to which fresh acid is supplied as required. The valve v is closed except when it is required to drain the casing. The casing is fitted with a ventilation i. The nitrated cellulose is forced through a pipe x and a perforated box 4, Fig. 5, on to a conveyer 5 which carries it beneath an adjustable pressure-roll 8 and an adjustable perforated air-roll 12 supplied from an air-compressor (not shown) with dry air withdrawn from the casing 3; an oscillating plate 7 on the box 4 levels out the layer. The product is removed from the conveyer by a paddle 17 and falls into a submersion chamber 19 supplied with water from a pipe 20, whereafter it is carried away through a flume line for further treatment. The conveyer is cleaned by an acid spray 21 fed with acid by the pump t, and the acid thus fed to the casing 3, together with that removed from the nitrated cellulose, is withdrawn by the pump t through a pipe 23.

When the unit 2 is moved to the left pressure rises in the passageway 5 to open the valve 33 through a diaphragm 19 and allow fluid from the reservoir to enter the passageway 12 to compensate for the difference between spaces 10 and 11. This difference causes the unit 8 to move more rapidly than the unit 2 when the latter is moved to the right so that the pressure in the passageway 5 is again increased to open the valve and allow fluid to return to the reservoir from the passageway 12. The valve also permits fluid to enter or leave the passageway 12 in response to temperature changes.

Abstract: 403,429. Treating sewage. BROWN, A., 3, Esholt Lane, Tong Park, near Shipley, Yorkshire. April 18, 1932, No. 11023. [Class 111.] For agitating sewage and other liquids or semiliquids, a rotatable shaft a is supported with its axis in the direction of flow of the liquid and is provided with vanes b spaced apart longitudinally and distributed circumferentially around the shaft so that the flow of liquid past the vanes rotates the shaft. The shaft is supported on a frame d which may be fixed in a channel or may be carried on a raft e which may be loaded to submerge the apparatus to a required depth. The shaft a may thus be above or below the surface. The spaced vanes may be in different or opposed helical planes or pitches, there being always an excess of vanes of one type sufficient to ensure continuous rotation. The vanes may be pivotally and adjustably connected to the shaft or may be bolted to short arms on a metal hub adapted to be threaded on the shaft.
Patent GB-735229-A (GB)
Title: Improvements in the production of phenols and carbonyl compounds
Filed: 1952-05-01
Abstract: In a process for the production of phenols and carbonyl compounds a hydroperoxide of an alkyl aromatic hydrocarbon of which at least one alkyl group contains a secondary or tertiary carbon atom and perchloric acid are brought into contact at elevated temperature in the presence of a quantity of the phenol to be formed in the reaction, the phenol being introduced before the reaction has commenced.  The hydroperoxide may be previously admixed with the phenol before being reacted with the perchloric acid or preferably the perchloric acid and hydroperoxide are added simultaneously to a hot mass of the liquid phenol (which may contain up to an equimolar amount of the carbonyl compound produced in the reaction).  The perchloric acid used may be e.g. 0.05 per cent up to about 1 per cent by weight of hydroperoxide and the reaction medium is homogeneous. Suitable hydroperoxides are those of cumene and its homologues, e.g. p-cymene, which yields p-cresol and acetone, isobutylbenzene which gives phenol and methyl ethyl ketone, and ethylbenzene which gives phenol and acetaldehyde.  A crude hydroperoxide, e.g. cumene hydroperoxide containing 5 per cent each of cumene and water or 10 per cent cumene, may be used.  Reaction temperatures below 65 DEG  C. are preferred.  The process may be effected continuously by adding hydroperoxide and perchloric acid to the heated phenol and simultaneously removing reaction products.  In examples: (1) phenol and acetone are produced continuously by passing perchloric acid and cumene peroxide into phenol and acetone at 40 DEG  to 50 DEG  C.; (2) cumene hydroperoxide containing water, cumene, phenyl dimethyl carbinol and acetophenone is used in a process as in (1); (3) the decomposition of cumene is effected under partial vacuum, the acetone produced being distilled off continuously. Specification 721,700 is referred to.
