Abstract
An apparatus for developing photosensitive material with a gaseous medium comprising a housing having a developing chamber therein, at least one rotor in said developing chamber, said rotor extending over substantially the entire width of material to be developed and being mounted at a distance of about 0.05 to 20 mm from the material to be developed, a device for introducing gaseous developer medium between the rotor and the interior walls of said chamber, and a device for passing material to be developed through the apparatus, whereby it contacts said gaseous developer medium.
Claims26
An apparatus for developing photo-sensitive material with a gaseous medium comprising housing means having developing chamber means therein,
- at least one rotor means in said developing chamber means, said rotor means extending over substantially the entire width of material to be developed and being mounted at a distance of about 0.05 to 20 mm from the material to be developed,
- the peripheral speed of the rotor means being at least twice as great as the speed at which the material to be developed passes through the apparatus when a point on the surface of the rotor and on that face presented to the material to be developed moves in the same direction as the material,
- means for introducing gaseous developer medium between said rotor means and the interior walls of said chamber means,
- and means for passing material to be developed through said apparatus, whereby it contacts said gaseous developer medium.

- the peripheral speed of the rotor means being at least as great as the speed at which the material to be developed passes through the apparatus when a point on the surface of the rotor and on that side presented to the material to be developed moves in the opposite direction to that of the material,
- means for introducing gaseous developer medium between said rotor means and the interior walls of said chamber means,
- and means for passing material to be developed through said apparatus, whereby it contacts said gaseous developer medium.
