Apparatus for separating finely divided liquid particles from gases comprises a closed vessel, a conduit passing through a wall of the vessel, a gauze collar extending coaxially with and downwardly from the end of the conduit inside the vessel so that the lower end of the collar is submerged in a pool of liquid in the vessel, and a duct through the vessel wall to one side of the plane which passes through the junction of the conduit and the collar and which is normal to the axis of the conduit, the collar and duct being on opposite sides of this plane. Gas with entrained liquid enters a vessel 1 through a conduit 4, large and medium sized droplets of liquid being thrown directly into a pool of the liquid 7 which stands in the bottom end of the vessel 1 and which serves to seal the lower end of a gauze collar 6. Any droplets impinging on the conduit walls flow down and drop off its bevelled lower edge 5 into the liquid 7. Coalescence of the smaller particles occurs as the gas passes through the gauze collar 6 which may be of metal or synthetic material of mesh size 0.1 mm. to 3 mm., the preferred mesh size being 0.3 mm. The liquid either runs down the gauze into the liquid or is blown off in droplets which impinge on the inner walls of the vessel and again flow down into the pool of liquid 7. Gas substantially free of liquid leaves the vessel by a duct 8 located opposite the upper third of the conduit while liquid overflows through a pipe 10. In another form, not shown, the conduit enters horizontally at the side and is bent through 90 degrees inside the vessel and the gas exit duct is located at the top of the vessel above and coaxial with the vertical section of the conduit. Formulae are given relating maximum and optimum velocities in the apparatus to the specific weight of the liquid and to the dynamic viscosity of the gas concerned.

[Class 98 (ii)] Mosaic screen additive colour pictures or kinematograph films are analyzed into records of the single component colours and each record used to prepare an etched printing plate or strip which is inked and the records printed in superimposition on a common receptive surface. The plates are prepared by printing by means of coloured light, colour filters, or stop-out screens onto light-sensitive layers on strips of etchable material without the use at any stage of a gravure or other photomechanical screen. The printing strips may be of celluloid or metal, e.g. copper. As sensitive material, a silver bromide emulsion or a carbon tissue sensitized with potassium or ammonium bichromate on a separate support may be used, the layer after exposure being transferred to the metallic strip. When a stop-out screen is used this may be separate from the metallic strip or may be applied thereto as a resist before or after the application of the sensitive layer. Preferably, the original mosaic screen consists of juxtaposed hexagonal areas of red, green, and blue, in which case the stop-out screen may cover slightly more than two-thirds of the area so as to allow latitude in registration. The receptive surface may be of paper or of cellulose acetate; when the latter is used, the printing ink preferably contains a solvent for cellulose acetate, e.g. acetone. Registration may be effected by printing a series of interrupted lines on the margin of the strip and scanning these with a photo-electric cell connected to means for displacing or stretching the strip if the lines come out of register with the cell.
