Title: Improvements in or relating to process for refining oils containing benzene
IPC: C07C7/00
Filed: 1950-11-28
Abstract: Oils containing benzene are refined by heating in the liquid phase at above 150 DEG  C. and under pressure to polymerize unsaturateds, the polymers are separated, and the oils catalytically hydrogenated.  The heat treatment is effected at such a temperature that cracking of the polymers formed does not occur, generally 180-300 DEG , preferably 200-250 DEG  C., for about 1/2 -1 hour or longer.  Hydrogen may be present.  The oil is then vaporized from the polymer residue by expansion or heat, e.g. by introducing hot hydrogen, and passed over the hydrogenation catalyst.  Crude benzene or benzene "first product" from the wash oil used for removing benzene from coal distillation gases may be treated.  It is pumped at 20-200, preferably 50-100, atmospheres through tubular heaters and reservoir vessels to form the polymers which remain as residue, preferably with sufficient low-boiling constituents to give a liquid which is removed and distilled, with recycle of the low boiling condensate.  The oil is vaporized by hydrogen-containing gas at about 350 DEG  C. and passed over oxides or sulphides of Group 5, 6 or 8 metals, condensed, and washed.ALSO:Oils containing benzene are refined by heating in the liquid phase at above 150 DEG C and under pressure to polymerize unsaturates, the polymers are separated, and the oils catalytically hydrogenated.

Title: Improvements in or relating to the processing of rice
Inventor: MCGINLEY FLANN ANTONY
IPC: A23L7/196
Filed: 1966-06-29
Abstract: In making cooked rice, e.g. quick-cooking rice, raw polished rice is cooked in water, e.g. at 50 DEG C., for sufficient time, e.g. 2 to 4 hours, to increase the moisture content of the rice to between 25 and 35%, based on the weight of the raw polished rice. A chelating agent, e.g. sodium acid hydrophosphate, and a starch-complexing agent, e.g. a monoglyceride such as glyceryl monostearate, or a mixture of such monoglycerides, are then added to the water and rice, and the resulting mixture is simmered, e.g. for 6 minutes at a temperature between 94 and 100 DEG C., to raise the moisture content of the rice to 65%, and effect substantial gelatinization.  The water is then drained off, and the remaining moist, cooked rice is treated with dry, live steam to complete the gelatinization of the rice, which is then washed with water, preferably cold water, to remove any free starch, and then dried, e.g. in air at a temperature between 60 and 100 DEG C., to yield cooked rice, e.g. containing between 8 and 16% of moisture.  The cooked rice may be subjected to mild mechanical pressure, to reduce any aggregates to discrete rice grains, as by passing it between two counter-rotating, preferably rubber-surfaced, rollers located 1/4 to 1 1/4 inch apart.  Between 0.05 and 0.5 of the chelating agent, and between 0.1 and 1.0% of the starch-complexing agent, computed on the weight of raw polished rice, may be used.  The chelating agent tends to enhance the whiteness of the cooked rice, and the starch-complexing agent tends to prevent its aggregation during drying.

Title: Improvements in or relating to electrodes for electrolytically producing uranium
IPC: C25C7/02
Filed: 1962-07-30
Abstract: Uranium is electrolytically produced from anode material comprising uranium oxide (e.g. <PICT:0968754/C6-C7/1> UO2 or U3O8) and carbon using a fused electrolyte, e.g. of one or a mixture of the fluorides of U, Ba and Li. The anode material is made by intermixing a uranium oxide with less than the stoichiometric amount of carbon required to reduce the uranium oxide to metal, baking the two together and crushing the resultant ceramic to discrete predominantly non-spherical particles and then mixing the particles with a carbon binder, the total amount of carbon in the particles together with that of the binder being at least equal to the stoichiometric amount required to reduce the uranium oxide to metal, moulding the mixture into a shape and baking the shape. The material may be moulded as electrodes which are square in cross-section or cylindrical. Alternatively, it may be moulded as pellets or larger moulded pieces may be broken to pellet size, the pellets being supported for use in a perforated carbon basket. Fig. 1 shows an anode 12 which can be advanced by a feeding or clutch mechanism 13 into a cathodic graphite crucible 10 containing a fused salt electrolyte 11.  Molten U collects at 16. Using cylindrical rod anodes, an electrolyte of 65% BaF2, 10% LiF and 25% UF4, and a voltage of 5.5 volts, the current efficiency in producing U was 22%.  Using an anode comprising cylindrical pellets in a carbon basket under the same conditions as above, the current efficiency was 48%.

Title: Improvements in machines for dressing fish
IPC: A22C25/14
Filed: 1936-10-28
Abstract: 461,806. Dressing fish. FISADCO, Ltd. (Baader, R.) Oct. 28, 1936, No. 29355. [Class 28 (ii)] In a fish-dressing machine, the brush or other device for scouring out the bellies of the opened fishes is controlled to move towards the fish, as it moves tail first past the brush, sufficiently deeply to detach the gut from its point of attachment at the tail end of the belly cavity, and thereafter to move slightly away from the fish so as to scour the belly cavity without damaging the belly skin. As shown the machine is of the general type described in Specifications 188,432 and 313,335, [both in Class 28 (ii)], the fish being clamped to the rotary disc 1 with its belly against the edge of the disc. When the fish reaches the brush 3 it has already been cut down the back. The brush is driven continuously from a shaft 7 through gearing 5, 6, the brush shaft 4 being journalled in an arm 9 which swings on the shaft 7. A spring 17 urges the brush towards the fish to the extent permitted by a roller 11, adjustable in a slot 13 in an extension 14 of the arm 9, contacting with cams 15, 16 rotating with the disc 1, and by an adjustable screw stop 18 which bears against a fixed abutment (not shown). The arrangement is such that the roller 11 may be adjusted in the slot 13, according to the average size of the fish passing through the machine, so that the brush moves towards the fish as the tail end of the belly cavity is in position to receive it. The gut is detached and the cam 16 then comes into operation to raise the brush slightly from the fish to preserve the belly skin.

Title: Improvements in or relating to a method of dot prescreening photographic sheet material
IPC: G03F5/00
Filed: 1956-09-28
Abstract: 845,419. Prescreened photographic sheet materials. KODAK Ltd. Sept. 28, 1956 [Sept. 30, 1955], No. 29672/56. Class 98(2) Effectively continuous prescreening as by Clayden or ordinary exposures directed to the production of vignetted latent dots is conducted by a step and repeat method with normally a 50% overlap of successive areas of the sensitive surface, but without lines of demarcation between such areas, by moving the material from a roll past an exposure area and illuminating the area for each step through a halftone screen to expose only approximately one-half of the dots, the dots exposed during each step being located midway between those exposed during the immediately preceding and succeeding steps. As shown, Fig. 3, film or paper 30 from roll 22 moved upwards by drive rollers 40 fitted with a precise metering arrangement so that broken line 34 moves to the position of line 33 and then to line 32 for exact 50% overlap; the screen 31 has only half or quarter of the apertures of a standard rule screen, and exposure for a first step position of the material 30 from lamp 37 effects prescreening dots 42, to be followed by exposure for the next step from lamp 39 for dots 43 between dots 42. The description referring to this figure includes data leading to the production of 133 line prescreened film. Variations described with reference to a total of 33 figures include instances in which the rows of dots of the screen run diagonally to the direction of movement of the film or paper and can be exposed from a single lamp and aperture for the successive steps, in which instances a contact screen may be used. In other alternatives two latent image dots are exposed through each screen opening for each step of movement using a pair of spaced exposure lamps in place of each of the single lamps 37, 39. The description, finally, is directed to a method by which three colour prescreening as on multilayer film may be effected continuously (step and repeat) with orientations close to those desired in three colour work using micrometer 201 for rotational adjustment of the screen 31 for the various exposures. Specification 699,659 is referred to.
