Abstract

Abstract A method and apparatus for processing a photosensitive material. The apparatus having at least one processing tank containing a processing solution for processing the photosensitive material, a replenishment system for replenishing the processing solution comprising a first part and a second part, the first and second parts each having independent usage rates, means for measuring the distribution of transmittance of the photosensitive material being processed by the at least one processing tank, and means for independently supplying the first and second parts to the at least one processing tank in accordance with the distribution of the transmittance of the photosensitive material being processed, the ratio of the volume of the first part to the volume of the second part to be delivered to the tank being at least 10 to 1.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 136 words
A processor for processing a photosensitive material, comprising: at least one processing tank containing a processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage rates; means for measuring a parameter of said photosensitive material being processed by said at least one processing tank, said parameter being representative of the extent of usage of said first and second parts of said processing solution; and means for independently supplying said first and second parts to said at least one processing tank in accordance with said measured parameter, the ratio of the volume of said first part to the volume of said second part to be delivered to said tank being at least 10 to 1.
Claim 2
Dependent Claim 136 words
A processor for processing a photosensitive material, comprising: at least one processing tank containing a processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage rates; means for measuring a parameter of said photosensitive material being processed by said at least one processing tank, said parameter being representative of the extent of usage of said first and second parts of said processing solution; and means for independently supplying said first and second parts to said at least one processing tank in accordance with said measured parameter, the ratio of the volume of said first part to the volume of said second part to be delivered to said tank being at least 10 to 1.
Claim 3
Dependent Claim 12 words
The processor according to claim 1 wherein said parameter is the transmittance.
Claim 4
Dependent Claim 159 words
A processor for processing a photosensitive material, comprising: a first processing developing tank and at least one other processing developing tank, each of said processing developing tanks containing a developing processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage and/or generation rates; means for measuring the distribution of infrared density of said photosensitive material after passing through said first processing tank and before passing through one of said at least one other processing tank; and means for independently supplying said first and second parts to said at least one processing tank in accordance with the distribution of said optical density of said photosensitive material being processed, the ratio of the volume of said first part to the volume of said second part to be delivered to said first processing tank being at least 10 to 1.
Claim 5
Dependent Claim 159 words
A processor for processing a photosensitive material, comprising: a first processing developing tank and at least one other processing developing tank, each of said processing developing tanks containing a developing processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage and/or generation rates; means for measuring the distribution of infrared density of said photosensitive material after passing through said first processing tank and before passing through one of said at least one other processing tank; and means for independently supplying said first and second parts to said at least one processing tank in accordance with the distribution of said optical density of said photosensitive material being processed, the ratio of the volume of said first part to the volume of said second part to be delivered to said first processing tank being at least 10 to 1.
Claim 6
Dependent Claim 128 words
A processor for processing a photosensitive material, comprising: at least one processing tank containing a processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage rates; means for measuring the distribution of transmittance of said photosensitive material being processed by said at least one processing tank; and means for independently supplying said first and second parts to said at least one processing tank in accordance with the distribution of said optical density of said photosensitive material being processed, the ratio of the volume of said first part to the volume of said second part to be delivered to said tank being at least 10 to 1.
Claim 7
Dependent Claim 128 words
A processor for processing a photosensitive material, comprising: at least one processing tank containing a processing solution for processing said photosensitive material; a replenishment system for replenishing the processing solution comprising a first part and a second part, said first and second parts each having independent usage rates; means for measuring the distribution of transmittance of said photosensitive material being processed by said at least one processing tank; and means for independently supplying said first and second parts to said at least one processing tank in accordance with the distribution of said optical density of said photosensitive material being processed, the ratio of the volume of said first part to the volume of said second part to be delivered to said tank being at least 10 to 1.
