Abstract

1406943 Aerating liquids BAYER AG 8 June 1973 [8 June 1972] 27342/73 Heading B1C [Also in Division C3] An apparatus for producing porous plastics from liquid precursors for a plastics material comprises a plurality of capillaries, 3, (e.g. in the form of bushings each of which contain a bundle of hexagonally close-packed copper wires of the same diameter which are arranged in the bottom, 1, of a container, 2, and which all communicate with a pressure connection, 4, suitable for feeding gases into liquid systems. The capillaries may be formed by (the spaces between) copper wires coated with polyethylene, and a plurality of the capillaries may be enclosed within a glass tube.
