Abstract

1354841 Photographic emulsion preparation AGFA-GEVAERT AG 9 Feb 1972 [11 Feb 1971] 5964/72 Heading G2C [Also in Division B1] A photographic silver halide emulsion is metered by a pump 3 to a tubular mixer and additives (such as sensitizing dyes, stabilizers, wetting agents, hardeners, optical brighteners and pH regulators) are metered by reciprocating pumps 5 to successive inlets between which these are only static mixing devices. The pumps 3, 5 have a common drive. As shown the tubular mixer is arranged in hairpin-like sections 4 and the static mixing devices are helical inserts 7. The inlets 6 are preferably multiple nozzles and the last two sections 4 have detection and control means 8, 9, 8', 9' to adjust the stroke of the pumps 5' to keep the PH and viscosity constant. Each tube section has a quick release end closure 13, Figs.2a, 2b (not shown) which supports the helix, and a heat exchange jacket (14). Preferably each helix has a ratio of lead a, Fig.3 (not shown) to the distance (b) from its core (7) to the inside of the tube of 2:1 to create turbulence (16).
