Abstract
An apparatus for processing photographic material comprises a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber, and a member located within the chamber and filling a central part thereof. A gap is defined between the inner wall of the chamber and the central member in which the material is held, thereby retaining the material around the inner circumference of the chamber.

An apparatus for processing photographic material comprising a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber, and a member located within the chamber and filling a central part thereof, a gap being defined between the inner circumferential wall of the chamber and the central member in which the material is located, thereby to retain the material around the inner circumference of the chamber.
An apparatus for processing photographic material comprising a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber, at least two entrance slots for the material to be processed being provided through the wall of the chamber and an equal number of film guide channels, of differing widths, provided in the inner circumferential wall of the chamber, thereby to guide and retain the material around the inner circumference of the chamber.
An apparatus for processing photographic material comprising a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber, a member located within the chamber and filling a central part thereof, a gap being defined between the inner circumferential wall of the chamber and the central member, the central member having at least one nest defined therein.
A method of processing photographic material comprising the steps of loading the material into a processing chamber the central part of which is filled by a central member, the walls of the chamber and the central member defining a gap in which the material is located, introducing processing solution into the chamber, agitating the solution and removing the solution from the chamber.
A method of processing photographic material comprising the steps of loading the material into a chamber adapted to hold the material therein, introducing solution into the chamber, and rotating the chamber, the volume of solution continuously sweeping over the surface of the material as the chamber rotates.
