Abstract

1382442 Developing apparatus TOWNSTAL PRODUCTS Ltd 20 Jan 1972 2856/72 Heading G2X A photographic film developing apparatus comprises a hollow, vertical, cylinder 10 provided internally with projecting ribs 15 supporting the convolutions of film which is introduced into the cylinder by removing an inlet cap 11, and, separating a film holding chamber 16 from a processing liquid chamber 17 into which the liquid is poured, following removal of a cap 20, through a funnel 13, fitted with a light-trap 21 such that the film is not contacted by the liquid prior to processing. For processing the film the cylinder is tilted into the horizontal position and tumbled for a predetermined period after the elapse of which it is tilted back into the vertical attitude and the processing liquid drained off by removal of cap 28 in a light-trapped outlet cap 12 provided with legs 14.
