Abstract: 1302593 Carbon dioxide absorption; ammonium sulphamate TOYO ENG CORP and MITSUI TOATSU CHEMICALS Inc 6 Feb 1970 [8 Feb 1969] 5790/70 Heading C1A CO 2  is removed from a stream of ammonia synthesis gas by scrubbing with liquid ammonia under at least the pressure required for urea synthesis and in the presence of a substance, selected from aqueous ammonia, aqueous urea methanol, or, preferably, water, which will aid the dissolution of ammonium carbamate, the amount of ammonia used being sufficient to keep the molar ratio of total NH 3 /CO 2  at the gas exit end of the scrubber above 3À0. Residual CO 2  is removed from the gas, e.g. by adding a small amount of water and subsequently separating the liquid again and/or by passing the gas through a methanization reactor, which also removes any CO which may be present. The gas is cooled by indirect heat exchange after this removal of residual CO 2  and not before. In Fig. 2 the gas enters at 1 and is scrubbed in column 2 by a mixture of liquid ammonia and aqueous ammonium carbamate; CO 2  is further removed by the introduction of water into the upper part of the column by pipe 7. The resulting solution flows to a urea synthesis plant (not shown) while the gas passes through methanization reactor 11, pre-heats the gas circulating in the ammonia synthesis loop in heat exchanger 13 and enters the loop via line 15. The ammonia carried over from the scrubber is recovered, together with that formed in the ammonia synthesis reactor 14, by means of condenser 21 and separator 23.

Abstract: 1,269,198. Spreading butter &c. I. FAHLSTROM A.B. 5 March, 1971, No. 6181/71. Heading A2A. Butter &c. in a container 3 is applied to slices of bread 44 by a reciprocating cutter and spreader blade 38 operation of which is synchronized through a pawl and ratchet or other mechanism (not shown) with means for applying incremental feed movements to a plunger (not shown) above the butter in the container. The blade 38, which may have a P.T.F.E. coating, has a cutting edge 41 and delivery slot 39 and an upper surface 40 to the left of the cutting edge which is lower than the surface to the right of the edge so that with the blade 38 in its rightward position butter can be displaced downwardly a distance corresponding to the thickness to be applied to a slice of bread. Leftward movement of the spreader then transfers a layer of butter to a slice, fed from a magazine 4 by a pusher 48, after which the spreader is returned to the right, together with the buttered slice which is transferred by the pusher to position 49 in readiness for the next cycle. The bread feed mechanism may be modified so that the buttered slice is displaced to the position 49 by the next slice to be buttered, thereby shortening the stroke of the pusher, or the pusher mechanism may be replaced by an endless belt feed. For spreading butter on non-resilient bread, e.g. crisp rye bread, a curved pressure surface 42 projecting below the blade 38 may be resilient. The container 3 which is detachable from the apparatus and formed with a jacket for cooling water may be of rectangular or circular cross-section to suit the shape of bread.
