Abstract: A method and apparatus for making flat topped foamed buns (e.g. polyurethane) in a continuous foaming process. In accordance with the method, continuous thin film tubular members are guided onto each side of the central trough defining conveyor of a continuous pouring system, and a central trough defining film member generally covering the central conveyor is guided thereover prior to the dispensing head. The edges of the tubular members are subsequently guided upward over guides at each side of the trough so that the tubular define upward sloping side walls traveling at an angle and rate determined in accordance with the rate of longitudinal travel and the rate of rise of the foaming reactants so as to encourage the sides of the bun to the same height of rise as the center region of the bun. Continuous slitting of the tubular members at an appropriate elevation allows the material thereof to progress longitudinally with the cured bun.

Abstract: This invention relates to novel N-acyl anilines, to a process for their preparation and to pharmaceutical compositions containing them. The N-acyl anilines are obtained by condensing a substituted aniline with an aminolower alkyl carboxylic acid or a functional derivative thereof.The compounds of the invention have therapeutic utility namely in the gastro-enterologic field.
