Abstract: A cartridge for receiving a photographic processing chemical comprises a main body formed with an outlet by way of which the chemical may be introduced into or removed from the cartridge. The main body also has a connection for a venting arrangement which provides communication between the interior of the main body of the cartridge and atmosphere when the cartridge is in use. The connection for the venting arrangement is located adjacent, and faces in the same direction as, the outlet in the main body so that in a single "plug-in" operation the cartridge can be located upon a processing apparatus to establish connections for the supply and return of the processing chemical and a connection with a venting arrangement provided on the processing apparatus.

Abstract: Dispensing apparatus are well known for dispensing material from a package. Described herein is apparatus for dispensing predetermined amounts of material (10, 10') stored in vessels (12) carried by a continuous web (14). Each vessel (12) comprises a body portion (15) and a cap portion (16) with one end (22) of a pressure sensitive strip (24) positioned therebetween, the other end (26) of strip (24) being attached to the continuous web (14). The apparatus comprises a roller (28) over which the web (14) moves. Tightening of the strip (24) as the web (14) passes over the roller (28) causes the body portion (15) of the vessel (12) to become detached from the cap portion (16) and the material (10') is released.

Abstract: The critical time in photographic processing apparatus is the time from when the first part of photographic material enters the apparatus to when the last part leaves the apparatus. During this time there are periods of time in which no processing takes place, for example, as the material is passed from one stage to the next. Described herein is a processing unit which minimizes the periods of time during which no processing is taking place. The unit comprises a processing tank (6) having processing solution (4) retained therein. Material (S) is fed into the tank (6) along a path (2), and around a looped path (8) until reaches a point (10) at which the material (S) can be deflected out of the tank (6), along path (14) and into a further processing tank (16), or can be deflected along path (12) so that further processing can take place in tank (6) prior to being passed on to the next stage.
