Abstract

Abstract For continuous development of x-ray film in a processing tank, a processing solution having a plurality of partial stocks diluted with water is replenished to the tank. The replenishing system includes a cartridge having discrete compartments partitioned therein and filled with the partial stocks and a storage tank having discrete compartments partitioned therein, wherein the partial stocks are transferred from the cartridge compartments into the storage tank compartments, respectively, and the partial stocks are then pumped from the storage tank compartments in amounts corresponding to a desired mix proportion of the partial stocks to the processing tank along with the diluent water.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 97 words
A method for replenishing a processing solution having a plurality of partial stocks diluted with a diluent to a processing tank, comprising the steps of: providing a cartridge having discrete compartments partitioned therein and filled with the partial stocks in amounts corresponding to a desired mix proportion of the partial stocks, transferring the partial stocks from the cartridge compartments into discrete compartments partitioned in a storage tank, respectively, and delivering the partial stocks from the tank compartments in amounts corresponding to the desired mix proportion of the partial stocks to the processing tank along with the diluent.
Claim 2
Independent Claim 97 words
A method for replenishing a processing solution having a plurality of partial stocks diluted with a diluent to a processing tank, comprising the steps of: providing a cartridge having discrete compartments partitioned therein and filled with the partial stocks in amounts corresponding to a desired mix proportion of the partial stocks, transferring the partial stocks from the cartridge compartments into discrete compartments partitioned in a storage tank, respectively, and delivering the partial stocks from the tank compartments in amounts corresponding to the desired mix proportion of the partial stocks to the processing tank along with the diluent.
Claim 3
Dependent Claim 46 words
The method of claim 1 in which the delivering step includes pumping partial stocks from the tank compartments and diluent water in amounts corresponding to the desired mix proportion and mixing the partial stocks with the diluent before the mixture is fed into the processing tank.
Claim 4
Dependent Claim 13 words
The method of claim 2 wherein the mixing step uses a static mixer.
Claim 5
Dependent Claim 29 words
The method of claim 1 wherein the transferring step includes dispensing the partial stocks from the cartridge compartments into the storage tank compartments in a chicken hopper manner, respectively.
Claim 6
Dependent Claim 36 words
The method of claim 1 which further includes the steps of: detecting the level of the partial stocks in the storage tank compartments, and indicating the replacement of the cartridge in response to the detected signal.
Claim 7
Dependent Claim 48 words
The method of claim 5 which further includes the step of controlling the delivery step and the indicating step such that the cartridge replacement is indicated when at least one of the detected levels of the partial stocks in the storage tank compartments is below a predetermined value.
Claim 8
Dependent Claim 17 words
The method of claim 6 which further includes the step of alarming the replacement of the cartridge.
Claim 9
Independent Claim 103 words
A system for replenishing a processing solution having a plurality of partial stocks diluted with a diluent to a processing tank, comprising a cartridge having discrete compartments partitioned therein and filled with the partial stocks in amounts corresponding to a desired mix proportion of the partial stocks, a storage tank having discrete compartments partitioned therein, means for transferring the partial stocks from the cartridge compartments into the storage tank compartments, respectively, and means for delivering the partial stocks from the storage tank compartments in amounts corresponding to the desired mix proportion of the partial stocks to the processing tank along with the diluent.
Claim 10
Independent Claim 103 words
A system for replenishing a processing solution having a plurality of partial stocks diluted with a diluent to a processing tank, comprising a cartridge having discrete compartments partitioned therein and filled with the partial stocks in amounts corresponding to a desired mix proportion of the partial stocks, a storage tank having discrete compartments partitioned therein, means for transferring the partial stocks from the cartridge compartments into the storage tank compartments, respectively, and means for delivering the partial stocks from the storage tank compartments in amounts corresponding to the desired mix proportion of the partial stocks to the processing tank along with the diluent.
Claim 11
Dependent Claim 31 words
The system of claim 8 in which the delivery means includes means for pumping partial stocks from the tank compartments and diluent water in amounts corresponding to the desired mix proportion.
Claim 12
Dependent Claim 32 words
The system of claim 9 wherein the delivery means further includes conduits extending from the storage tank compartments to the processing tank and the pumping means includes pumps located in the conduits.
Claim 13
Dependent Claim 11 words
The system of claim 10 wherein the pumps are bellows pumps.
Claim 14
Dependent Claim 30 words
The system of claim 9 in which the delivery means further includes means for mixing the partial stocks with the diluent before the mixture is fed into the processing tank.
Claim 15
Dependent Claim 13 words
The system of claim 12 wherein the mixing means is a static mixer.
Claim 16
Dependent Claim 29 words
The system of claim 8 wherein the transferring means includes chicken hopper means for continuously dispensing the partial stocks from the cartridge compartments into the storage tank compartments, respectively.
Claim 17
Dependent Claim 38 words
The system of claim 8 which further includes means for detecting the level of the partial stocks in the storage tank compartments, and indicator means for indicating the replacement of the cartridge in response to the detected signal.
Claim 18
Dependent Claim 47 words
The system of claim 15 which further includes means for controlling the delivery means and the indicator means such that the cartridge replacement is indicated when at least one of the detected levels of the partial stocks in the storage tank compartments is below a predetermined value.
Claim 19
Dependent Claim 16 words
The method of claim 16 which further includes means for alarming the replacement of the cartridge.
