The die is held to the bed-plate by loops 7 which engage projections 8 thereon. In operation, the spindle c and male die w descend together until the latter rests on the paste. The spindle c then descends alone so as to compress the air in the recess s until the flange c<3> contacts with the die o, whereupon both again descend until the rim o<1> rests on the edge of the mould 5. The valve w then opens and releases the compressed air so as to force the moulded article from the male die on its upward path.

Abstract: 1513152 Prevention of reactor fouling during polymerization BP CHEMICALS INTERNATIONAL Ltd 21 Aug 1975 [8 Aug 1974] 34991/74 Heading C3P Fouling of the wall of a polymerization reactor during polymerizations in which the polymerization mixture moves with respect to the wall, is prevented by adding particles to the polymerization mixture and removing them from the polymer produced. The particles, which may be ceramic (e.g. porous pot, or a synthetic alumino silicate) abrade the reator wall as the polymerization mix moves, and thus remove scale as it is formed. The particles are preferably present in an amount of 0À1 to 1À0 wt. per cent, based on the total weight of the reaction mixture. The process is especially applicable to the aqueous suspension polymerization of vinyl halides. The particles may be removed by filtration screening, or sedimentation.
