Abstract: 1,186,770. Separating foreign objects from rubber. FRENCH OIL MILL MACHINERY CO. 14 Nov., 1967, No. 51857/67. Headings B2A and B2H. [Also in Division C3] Foreign objects, such as dirt, sand, twigs and bark are separated from coagulated chunks of rubber by conveying the chunks to a shredder in which they are reduced to smaller pieces for releasing the embedded foreign objects, collecting the pieces within a chamber containing liquid to a depth sufficient to provide for settling of the foreign objects and floating of the pieces, withdrawing liquid with rubber pieces therein adjacent the surface of the liquid in the chamber to form a slurry and draining the liquid from the rubber pieces. The chunks C of rubber, Fig. 1 are fed by means of a conveyor 10 into a screening apparatus 12 which comprises a screen 15, Fig. 2 mounted within a frame 16 supported in an inclined position on a housing 18 by means of coil springs 20. The screen is vibrated by an eccentric weight 22 rotated through belt drive 25 by a motor 24. As the chunks move down the screen 15 they are washed of loosely adhering foreign objects by liquid sprayed from nozzles 27. The washed chunks are received in a hopper 29 to which liquid is added at 38. From the hopper the chunks are fed to a shredder 30 which may be of the type having a rotary drum with a series of axially extending chopper knives around its periphery and a half inch to one inch semi-circular screen. The shredded pieces A of rubber pass through a semi-cylindrical screen adjacent the bottom portion of the shredder drum together with liquid and are received in a settling chamber 40 in a tank 42 which includes an agitation chamber 44 separated from the chamber 40 by a weir 45. Liquid is maintained at level 46, e.g. by topping up as at 48. The relatively heavier foreign objects settle to the bottom of chamber 40 and are removed as sludge by a pump 50. The liquid and floating rubber pieces A flowing over the weir 45 are circulated in the chamber 44 and removed as a slurry by means of a pump P. The slurry may then be fed to a second and, if desired, third stage of washing, shredding and settling. The shredder 60 in the second stage of the twostage apparatus shown may be of the type having rigid hammers and a half inch (or smaller) perforated plate. The slurry from the last stage is fed via a line 68 and a pump 69 to a dewatering screen 12b from which the partially dried pieces of rubber are fed to a dewatering screw press 70 and to a dewatering and drying screw press 75.

Abstract: 1,175,919. Lubricating tubular casings. KALLE A.G. 20 Nov., 1968 [22 Nov., 1967], No. 55053/68. Heading B5B. [Also in Division B2] The interior surface of a regenerated cellulose tube, for use as a sausage casing, having an initial water content of more than 20%, is coated with a physiologically acceptable lubricant the the tube is then dried to a water content of 14 to 20% by weight while retaining the lubricant prior to shirring. Suitable lubricants include liquid paraffin and oily or solid natural and synthetic fatty acid glycerides. A more uniform coating is obtained when the coating is effected with a solution of the lubricant in a readily volatile solvent such as methylene chloride which evaporates during the drying process. As shown, the upper leading end of the extruded tube is fed manually from delivery container 1 at the start of the operation around a guide roller 8 in a flattened state and led downwards and passed around a second guide roller 2. Lubricant is advantageously introduced into the open leading end of the tube after it has been led around roller 2 and before it has been passed between the first pair of nip rollers 3. Between guide roller 8 and nip rollers 3 the portion of the tube not containing lubricant 10 is filled with air which enters when the lead end of the tube is introduced into the apparatus. After passing nip rollers 3 and being deflected by guide roller 9 the tube is passed through a drying chamber 5 between two pairs of nip rollers 4 and 6. When the lead end of the tube has been passed between nip rollers 6 the latter are opened and air is introduced into the tube so that after the nip rollers 6 have been closed the tube remains inflated during the drying process. The dried tube is wound on reel 7 and can then be fed into a shirring machine.
