Abstract

1322016 Degassing emulsions; evaporators. film-type AGFA GEVAERT AG 16 June 1970 [12 July 1969] 29007/70 Headings BIB and B1M [Also in Division G2] An apparatus for homogenising and degasifying photographic emulsions comprises a falling film evaporator 2 and a pump 3 for recycling the emulsion through the pipe 5 from the outlet to the inlet of the evaporator. Part of the recycling emulsion can be removed through the pipe 6 to the coating device 1, where it is applied to a web 4. Water and fresh emulsion may be added from the storage vessel 7. Ballast steam to operate the evaporator is injected through the injector 9, and the water and other vapours removed from the emulsion are taken off through the tube 10. The dotted line 8 indicates very diagrammatically means for controlling the float mechanism in storage vessel 7 depending on the level of liquid below the falling film evaporator 2. Reference has been directed by the Comptroller to Specification 1,287,913.
