Abstract: 1,164,411. Cleaning centrifuges. WESTFALIA SEPARATOR A.G. 29 Jan., 1968 [9 Feb., 1967], No. 4452/68. Heading B2P. A centrifuge having a solids collector 9 adjacent the base of the centrifuging drum 1 is cleaned by feeding a flushing medium, e.g. hot water or vapour, into the -drum and supplying a cooling liquid to the gap 11 between the drum and the. collector. With this arrangement, vapours which are likely to pass through the gap 11 and into the ball bearings 21, 22 and the drive 23 are condensed by the cooling liquid and thrown therewith by the rotating drum into the collector 9 from which they are discharged together. The centrifuge may be of the conical-plate type as shown having a feed inlet pipe 15, a liquid outlet 19 and solids discharge conduits 7 leading to ejection nozzles 8. The flushing medium is introduced into the drum after a centrifuging operation by connecting the pipe 15 to a flushing medium line 18 by means of a three-way valve 16. The medium discharges from the drum partly through the outlet 19 into the liquid collector 20 and partly through the nozzles 8 into the solids collector 9. Cooling liquid is fed via a connector 13 and a tap 14 to an annular distributor tube 12 provided on its periphery with bores 12a which are aligned with corresponding bores or notches which are provided in the base 10 of the collector 9 and which open out into the gap 11.

Title: Improved method and apparatus for forming lips on containers
IPC: B21D51/26
Filed: 1965-02-03
Abstract: 1,101,031. Rim rolling machine. HAVEG INDUSTRIES Inc. 3 Feb., 1965 [11 May, 1964], No. 4603/65. Heading B5A. [Also in Division B6] A beaded lip is formed upon a foamed plastics container by passing it between a series of helically grooved rotating heated rollers disposed in a circle about a common central axis. A compressive force is imposed upon the rims of the containers in the direction of their extent by the rollers and this coalesces them into lips having a density slightly higher than the rest of the container. In one embodiment, for use with containers in which the outer portion of the rim extends axially, an axial pressure is imposed upon the rims by using rollers, the grooves in which decrease in axial width, but remain of constant depth, over the length of the rollers. In a second embodiment, for use with such containers, each of the rollers is provided with a helical groove of constant width and depth. The pitch 238 of the grooves in each alternate roller differs from the pitch 242 of its neighbouring roller so that, over the length of the rollers, the axial distance 247 between the lower face 220 of the grooves in one roller and the upper face 222 of the groove in its neighbours decreases. Consequently the necessary axial force can be applied to the rims. In an embodiment for use with containers having radially extending rims, radial pressure is applied by providing the rollers with grooves which have a constant width but which decrease in depth over the length of the rollers. In a second embodiment for use with such containers both the width and depths of the grooves may be constant, the necessary radial compressive force being applied by making the axes of the rollers slightly convergent.

Title: An improved process for the direct obtention of high-percentage acetic acid from the mixture of acetyl cellulose and acetic acid which results in the preparation of acetyl cellulose
IPC: C08B3/22
Filed: 1930-02-11
Abstract: Acetic acid is recovered by atomizing the acetylation reaction mixture into a chamber containing heated air at a temperature not exceeding 80 DEG  C., the cellulose acetate being deposited in flakes, while the acetic acid is recovered by cooling the air containing its vapour.  The hot air is led through the atomizing chamber, and any cellulose acetate carried away may be caught in dust filters. The atomization may be effected with the hot air.  The removal of the acetic acid vapour from the atomization chamber may be assisted by evacuation, and if the vacuum is sufficient, the supply of hot air may be dispensed with.  The cellulose acetate may be caused to separate in coarser flakes by previously adding to the cellulose acetate solution an organic liquid such as benzene or toluene which precipitates cellulose acetate.ALSO:Acetic acid is recovered and cellulose acetate obtained by atomizing the acetylation reaction mixture (in which the sulphuric acid if used may have been neutralized) into a chamber containing heated air at a temperature not exceeding 80 DEG  C., the cellulose acetate being deposited in flakes, while the acetic acid is recovered by cooling the air containing its vapour.  The hot air is led through the atomizing chamber and any cellulose acetate carried away in the gas mixture may be caught by dust filters. The atomizing of the cellulose acetate solution may be effected with the hot air.  The removal of the acetic acid vapour from the atomization chamber may be assisted by evacuation, and when a sufficiently high vacuum is employed the supply of hot air may be dispensed with.  The cellulose acetate may be caused to separate in coarser flakes by previously adding to the cellulose acetate solution benzene, toluene or some other organic liquid which precipitates cellulose acetate.

Abstract: 522,676. Fire-extinguishing. MINIMAX, Ltd., and HATCH, J. H. Sept. 17, 1938, No. 4759/40. Divided out of 519,215. [Class 47 (ii)] A gas generating cartridge for use in an extinguisher 2 using an extinguishing liquid such as carbon tetrachloride is operated by a plunger 24 which carries forward a casing 1 of the cartridge so that an anvil 22 ruptures a disc 21 of metal foil and at the same time moves the casing 1 relatively to a supporting member 5 whereby a head 5a fractures an acid bottle 7. This releases the contents to react with a carbonate in compartment 11 of the cartridge. Gas thus generated passes through sawdust or other filtering material in a compartment 13 and passes out by an opening 20 into a casing 2 of the extincteur whereby liquid is ejected under considerable pressure by a nozzle 25. Any upward surge of acid is prevented by the filtering material in the chamber 13. Preferably sodium or potassium bicarbonate in crystal form is used with sulphuric acid but magnesium carbonate is an effective substitute as it does not cake and it may be used with hydrochloric acid. Specification 519,215 is referred to.
