Abstract: 1,160,540. Vegetable topping machine. M. W. FARROW. 8 April, 1968, No 16716/68. Heading A4C. A machine for topping tapering vegetables, e.g. carrots, comprises a drum-like cage 1 to which carrots are fed by shoots 10, the spacing of bars 2 being such to select a given grade of size of carrot, the smaller carrots falling between the bars into shoot 11. As the cage 1 rotates the trapped carrots pass a row of individually pivoted metal flaps 13 which push any remaining small carrots between the bars and help the correct sized carrots to come into the correct position 28. The carrots are then carried round to another set of flaps pivoted as a whole which pushes them down between the bars 2 so that only the required height of carrot for topping protrudes above bars 2. The emerging carrots are brought against a longitudinally extending cutting blade 22 which cuts off the tops of the carrots which fall away down a shoot 25. The remainder of the carrots are carried round by cage 1 until the body of each carrot is knocked by the heavy rubber flap 26 and the carrots fall away to be collected and packed. A second topping machine having closer spaced bars may be used which is fed the undersized carrots from above.

Patent GB-252308-A (GB)
Filed: 1925-07-06
Abstract: 252,308. Wolf, H. May 22, 1925, [Convention date]. Hydrocarbons, cracking.-In a continuous process for cracking hydrocarbon oils by heating them under pressure while passing through a cracking furnace, the cracked products are on discharge mixed with a liquid such as a high-boiling hydrocarbon, which takes up carbon and substances which tend to deposit carbon on heating. The temperature of the liquid may be such that vapours of high and low boiling hydrocarbons pass through it. The vapours are separated by fractional condensation, and the high-boiling hydrocarbons returned to the cracking process. Alternatively the whole of the vapours may be condensed in the liquid which is afterwards distilled. The liquid may be circulated from the vessel receiving the cracked products through a heat exchanger serving to preheat the oil to be cracked. Oil from a tank A is forced by a pump P. through preheating coils 3, 5 in tanks B, C and through a cracking coil 7. The cracked products are discharged through an expansion valve 10 and draw with them high-boiling oil from a tank E or oils from the tanks B, C admitted through valves 31, 28. The mixture passes by a pipe 14 into the tank 5. Liquid products are discharged through a siphon 1 and cooler 18 to a tank F from which they may be returned to the tank E. Vapours rise through a pipe 19 into a tank B. The highest boiling fractions condense and are discharged through a siphon 21 and cooler 22 into the tank A. The remaining vapours pass through a pipe 23 to a dephlegmator G to a final condenser H. The pipes 19, 23 may be fitted with baffle plates or filled with Raschig rings to separate utrained liquid.

Abstract: Aliphatic dinitriles containing at least 3 carbon atoms are prepared by passing anhydrous ammonia into a heated liquid half ester of an aliphatic dicarboxylic acid containing at least 3 carbon atoms or a salt, amide or nitrile thereof, either in the presence or absence of a catalyst, and under atmospheric, elevated or subatmospheric pressure.  In the examples, monomethyl adipate is treated with ammonia in the presence separately of catalysts consisting of phosphoric acid, and boron phosphate, in the former case under two different conditions of reaction.  The residues from the preceding examples are bulked and treated in the same way with a phosphoric acid catalyst.  Other suitable half esters are methyl, ethyl, n- and iso-propyl and n- and iso-butyl esters of malonic acid, succinic acid, adipic acid, sebacic acid and dodecamethylene dicarboxylic acid, whilst other catalysts may be phosphate catalysts such as acid salts and pyrolytic derivatives of phosphoric acid, ammonium phosphate, molybdate, tungstate, vanadate, phosphomolybdate, sulphate and chromite.  The catalysts mentioned in Specification 494,236 may also be used.  The ammonia used may be diluted with nitrogen, carbon dioxide or vapours of benzene or toluene, and is used in excess, while the liquid into which it is passed is violently agitated.  The products are carried over by the excess ammonia and condensed, the dinitriles being separated by fractional distillation or solvent extraction followed by distillation.  The process may be continuous or batchwise and partially converted material may be recycled.
