Abstract: An ammoniated phosphoric acid suitable for use as a fertilizer is produced by heating an aqueous solution of orthophosphoric acid, e.g. containing 35-65% P2O5 by wt. such as wet process acid containing 45-54% P2O5, to a temperatur of 110-160 DEG  C., in a closed vessel to a maximum gauge pressure of 0.35-5.25 kg./cm.2, e.g. 0.7-2.1 kg./sq. cm. at 115-124 DEG  C., but not above the boiling point at maximum pressure and then adding anhydrous ammonia at a rate to generate sufficient exothermic heat to raise the pressure above said maximum pressure to boil the solution.  The ammonia is preferably added in a weight ratio of N:P2O5 in the range 1:6.4 to 1:16 and at the rate of 0.1-3 moles/min./kg. of orthophosphoric acid.  An anti-foaming agent may be added, e.g. 0.2-1.0 parts of sodium dodecyl benzene sulphonate per 500 parts of orthophosphoric acid. The external heating is terminated prior to the addition of ammonia so that all the additional heat required for evaporation of water is supplied by the exothermic heat of reaction.

Class 100(1) In a sheet-delivery device for rotary printing machines suction applied for retarding the delivery of individual sheets is varied in dependance on the speed of the printing machine. Sheets delivered by a conveyer 2 on to a stack 3 pass over a retarding roller 4 by which suction is applied to the end of a sheet passing over the roller, the timing of the suction being controlled by valve 6. In a vacuum pipe leading from the valve 6 to an independently driven suction source 5 is a throttle 7 which is controlled by a centrifugal governor 8 connected to the drive of the printing machine. Thus, as the speed of the machine increases the throttle 7 allows a greater amount of suction to be applied to the sheets. In an alternative embodiment the throttle 7 is located in a branch pipe leading from the main vacuum pipe to the atmosphere (Fig. 2, not shown).
