Abstract: 1394124 Removing soot from water SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 4 April 1972 [6 April 1971] 15383/72 Headings C1A and C1C A process for removing soot from an aqueous suspension comprises, in a mixing zone, mixing the suspension with a water-immiscible auxiliary liquid under turbulent conditions to form a dispersion of agglomerates of soot and auxiliary liquid in water, and, in a separating zone, bring- ing the aqueous dispersion of agglomerates into contact with an unstirred phase of waterimmiscible auxiliary liquid whereby the agglomerates pass into this phase, discharging a substantially agglomerate-free aqueous phase and mechanically removing the agglomerates from the auxiliary liquid phase. The auxiliary liquid used in the separating zone may be the same or different to that used in the mixing zone. The auxiliary liquid may be one or more of toluene, benzene, gasoline and naphtha. The aqueous suspension may be produced by washing synthesis gas with water. The temperature and pressure in the zones may be respectively 40- 160‹ C. and 1-15 kg./cm.<SP>2</SP>. The discharged aqueous phase may have ash removed therefrom by flotation and then may be used to wash soot-containing gas. The separated agglomerates may be dried on inclined heated plates and dispersed in a heavy oil (e.g. fuel oil) or dried to a powder using inclined heated plates and/or a fluidized bed using superheated steam. In Fig. 2 the soot suspension from line 8 and auxiliary liquid from line 9 is mixed by rotating stirrers 6 in zone 1 and the resultant agglomerate dispersion is passed to zone 2 where the agglomerates pass into auxiliary liquid phase 12 supplied with liquid from line 13, and the separated water is discharged through line 10. The agglomerates are removed from phase 12 by Archimedean screw 15 and passed to evaporator 39 supplied with hot heavy oil from lines 42 and 46. From evaporator 39 evaporated auxiliary liquid is passed through line 41 to tray-type stripper 48, a portion of agglomerates and oil is recirculated to line 42 and a portion of agglomerates and oil is passed to stripper 48 supplied with steam from line 52. A suspension of soot in oil is discharged through line 51 and steam and auxiliary liquid vapour are discharged through line 49 to condenser 53 from which water is discharged through line 54 and auxiliary liquid is discharged through line 55 for return to stripper 48 by line 56 and the zones 1 and 2 by line 36.

Apparatus for closing cartons comprises latching means for inserting tongues (e.g. on a lid) in apertures, which includes inserting members moved along the path of the cartons by the cartons themselves and means to extend the members laterally into the carton path. Cartons.-The invention is described as applied to egg cartons 12 of 6 x 2 capacity with an integral or attached lid 14. The lid may be of plastics and attached to the body by a flange 26. A flange 28 carries five tongues 30 which are pressed into recesses 20, Figs. 3, 10 (not shown), formed in the front wall between the egg pockets. The lid may be separate and have flanges and tongues on both sides, in which case the tongue inserting mechanism is duplicated (not shown). Closing apparatus.-The cartons are advanced continuously by a belt 36 and the lid 14 folded down by a plough 52. Ploughs 56, 58 then engage opposite sides, the former to fold down the flange and the latter to apply counter pressure. A belt 64, moving slightly faster then the belt 36, holds down and advances the lid to correct back drag due to the plough 52. In one embodiment of tongue securing device, a starwheel having a carton engaging rounded tip 136 at the end of each of twelve fingers, is mounted for free rotation between plates 90, 92. Slidable radially by plate cam means along all but two diametrically opposite of the fingers, are the inserting members 144, see also Fig. 7 (not shown). A spring-loaded arm 114 carries a detent which enters either of two diametrically opposed recesses in the wheel to ensure that, in the rest position, a finger not carrying an inserting member will be positioned in the path of the carton. When this is engaged by the carton, the wheel rotates so that the following five fingers each enter a space between the egg pockets and the inserting members slide outwardly of the fingers to press the tongues home. In a second embodiment (Figs. 11-17, not shown), the fingers and inserting members are integral and carried on an endless chain. Along the chain's upper reach, the integral members are projected outwards by a cam track, both to engage the cartons and to press in the tongues. The chain is driven, as before, by contact between the carton and fingers.

Food products such as french fried potatoes, potato chips, hash browned potatoes, seafood such as shrimp and fishmeat, snack foods, bismarks, fried cakes and doughnuts, are prepared for frying by drying the surface of the product in order substantially to reduce its moisture content while leaving the moisture content of the interior of the product substantially unchanged, and chilling the dried surface to form an expandable protective surface or skin capable of resisting permeating by a fluid frying medium. Thus the product may be subjected to a blast of hot air at a temperature in the region of 600‹-800‹F. for 2-5 seconds and immedidately thereafter to a blast of cold air at a temperature in the region of -30‹F. for approximately 5 seconds and may then be fried; movement of the product along an elongate conveyer may be effected at least in part by means of the blasts of air directed on to the product in a generally upward direction. Alternatively, the product may be dried for three minutes in an oven at 400-450‹F. and cooled for about two minutes in a refrigerated chamber at -30‹F. In a further disclosure, drying takes place for 1¢ minutes at 375‹ or 575‹F., cooling for 1 minute at 0‹F. or 1¢ minutes at 10‹F. The drying treatment may be sufficient to cook the surface of the product while leaving the interior in a substantially raw condition. The chilling treatment may be effected either so rapidly that the internal temperature of the product remains substantially unchanged or during freezing of the complete product for cold storage.
