Patent GB-245929-A (GB)
Title: Improvements in machines for emulsifying and for disintegrating solids suspended in liquids
IPC: B01F5/00
Filed: 1925-01-02
Abstract: 245,929. Hurrell, G. C. Jan. 2, 1925. Emulsions, making. - Relates to emulsifying machines of the kind in which a thin film of the liquid passes through a narrow gap between two coacting surfaces moving at high speed with regard to each other, the liquid being fed through the hollow shaft of the motor and radial holes therein. To ensure that the materials treated are kept free from entrained air from their entrance to the machine until they emerge from the gap, the outer ends of the radial holes in the rotor are constricted and means are provided for automatically drawing up the material discharged by gravity from the machine and returning it to the working gap for further and repeated treatment. The rotor 20, Fig. 1, mounted on a shaft 18, which has a passage 24 extending from one or both ends to the mid-length of the rotor, has one or more radial holes 22 constricted at their outer ends by means of nipples 25 provided with screws 26 for adjusting their apertures. Or removable nipples may be secured in the ends of the passages 22. The rotor works within a short jacketed cylinder 10 having a smooth parallel or slightly tapered bore and provided with end covers 12, 13. The rotor is adjustable longitudinally by means of a hand-wheel 40 which is held against axial displacement by means of flat sectors 38 secured to the cover 13 and engages a screwed part 30 secured to the housing 34 that contains the ball bearing 28<a> for the shaft 18. The open end of the shaft 18 communicates with the T-shaped enlargement of the part 30 and may be fixed in a sleeve 37 by means of a hollow nut 36. Packing 32 between the part 30 and the sleeve 37 is compressed by means of a nut 29. For repeatedly passing the materials through the machine, the outlets 55 in the end covers are led to a receptacle 51 preferably having a conical bottom and into which projects a suction pipe 50 from one branch of the T-piece 30, the opposite inlet X of which communicates through a cock or valve 35 with the supply vessel 52. The larger particles suspended in the liquid settle in the lower part of the tank 51. Or the branches of the piece 30 may be connected to two or more supply vessels containing for example oil and an aqueous solution it is desired to emulsify. Fig. 3 shows a vertical machine, the hollow shaft 18 extending into a vessel 51a into which the outlet pipes 55 discharge; priming is effected by extending the hole through the upper end of the shaft 18 and providing thereon a supply vessel, or preferably by means of a small injector nozzle 57. Specifi. cation 214,308 is referred to.
Patent GB-737279-A (GB)
Title: Preparation of phytic acid
IPC: C07F9/117
Filed: 1953-01-05
Abstract: Aqueous phytic acid solutions are obtained by contacting an aqueous slurry of calcium, magnesium or calcium-magnesium phytates, or mixtures thereof, with a cation exchange resin, operating in the hydrogen cycle, so as to solubilize a substantial proportion of the phytate.  Preferably additional phytate, up to about a chemical equivalent amount, is dissolved in the phytic acid solution thus obtained advantageously until the pH is about 3 to about 4 and the resultant solution filtered and passed over a column of the resin. The process is then continued with partial recycle of aqueous phytic-acid for the solution of fresh quantities of phytates. Alternatively the aqueous slurry of the phytate is initially partially solubilized by the addition of an acid such as hydrochloric, sulphuric, acetic or preferably nitric acid, until the pH reaches about 3 to about 4, the resultant solution filtered and the filtrate neutralized to reprecipitate the phytate which is recovered and treated either as an aqueous slurry or after solution in aqueous phytic acid with an acid regenerated cation exchange resin.  Sulphonated polystyrene and coal resins are specified.  It is stated that the addition of 0.1-0.5 per cent of sodium chlorite, nitric acid or sodium nitrate may be effective in preventing colouration of concentrated aqueous solutions of phytic acid on storage and for this reason when a method involving a partial solubilization with nitric acid is used all sodium nitrate should not be removed from the final product since this compound is also effective as a colour preventer.  Examples of the above processes are provided using calcium phytate as starting material.

Abstract: 523,719. Tea manufacture. MEARES, C. H. Jan. 10. 1939. No. 854. [Class 129] [Also in Group II] . Withered tea leaves, before they are curled and twisted in a tea " roller " or " rapid roller," are partly crushed by passage between two oppositely rotating rollers spaced apart sufficiently to ensure that the cells are broken without disintegration of the leaves. The apparatus shown in Figs. 1 and 2 has rollers 10, 11 geared together by spur wheels 21, 22, the bearings 24 of the roller 11 being mounted in slide blocks 25, so that the nip of the rollers can be finely adjusted. The rollers may be of rustless steel and may be smooth, roughened or rigid. Adjustment of the roller 11 is effected by means of a spindle 31 supported on bifurcated arms 30 on sleeves 29 surrounding rods 27 which screw through. brackets 26 on the frame of the press and have heads 28 loosely fitting in recesses in the side blocks 25. The spindle 31 has worms engaging worm wheels 32 on the rods 27, so that the blocks 25 are moved when the spindle is turned by a handle 33. The leaves are fed to the rollers by a hopper 34 having internal ribs or vanes 35 and an elongated outlet slot. The hopper is pivotally mounted on pivoted arms 38, one of which has its lower end fitted with a roller engaging a small cam 42 rotating with spindle of the roller 10, so that the hopper is caused to oscillate longitudinally. Scrapers 44 mounted on pivots 45 and connected at their lower edges to adjusting rods 48 are held in contact with the rollers 10, 11 by tension springs 46.
