Abstract

According to the present invention we provide a method for the preparation of a liquid for supplying to one or more pieces of apparatus using such a liquid characterized in that one or a plurality of vessels visit one or more preparation stations until the liquid is prepared, and the liquid when prepared is continually supplied to the apparatus in batches by at least one vessel, the rate of liquid preparation and the vessel movements being matched to the requirements of each preparation station and/or each piece of apparatus. Preferably a plurality of vessels visit the preparation stations.

Claims

1. A method for supplying liquid to one or more pieces of apparatus characterized in that one or a plurality of vessels visit one or more preparation stations until the liquid is prepared and the liquid when prepared is continually supplied to the apparatus in batches by said one or a plurality of vessels, the rate of liquid preparation and the vessel movements being matched to the requirements of each preparation station.

2. A method according to claim 1 for the preparation of a liquid for supplying to one or more pieces of apparatus using such a liquid characterized in that a plurality of vessels visit one or more preparation stations.

3. A method according to claim 1 characterized in that the liquid being prepared is a coating dispersion.

4. A method according to claim 1 characterized in that one or a plurality of vessels are moved automatically subject to a central control.

5. A method according to claim 1 characterized in that said one or a plurality of vessels are moved by conveyor.

6. A method according to claim 1 characterized in that said one or a plurality of vessels are raised into position at said one or more preparation stations.

7. A method according to claim 6 characterized in that said one or a plurality of vessels are weighed at least one preparation station.

8. A method according to claim 1 characterized in that the capacity of a vessel is in the range 50 to 1000 liters.

9. A method according to claim 3 characterized in that the coating dispersion is coated onto a photographic support.

10. A method according to claim 1 wherein the method is used to make a photosensitive silver halide emulsion.

17. A method according to claim 6 characterized in that said one or a plurality of vessels are weighed at at least one preparation station.

18. A method according to claim 1 characterized in that the capacity of a vessel is in the range 50 to 1000 liters.

19. A method according to claim 3 characterized in that the coating dispersion is coated onto a photographic support.

20. A method according to claim 1 wherein the method is used to make a photosensitive silver halide emulsion.

24. A method according to claim 1 characterized in that said one or a plurality of vessels are moved by automatic guided vehicle.

25. A method according to claim 1 characterized in that said one or a plurality of vessels are moved by conveyor.

27. A method according to claim 1 characterized in that said one or a plurality of vessels are moved by automatic guided vehicle.

11. A method for supplying liquid to one or more pieces of apparatus characterized in that one or a plurality of vessels visit one or more preparation stations until the liquid is prepared and the liquid when prepared is continually supplied to the apparatus in batches by said one or a plurality of vessels, the rate of liquid preparation and the vessel movements being matched to the requirements of each piece of apparatus.

12. A method according to claim 11 for the preparation of a liquid for supplying to one or more pieces of apparatus using such a liquid characterized in that a plurality of vessels visit one or more preparation stations.

13. A method according to claim 11 characterized in that the liquid being prepared is a coating dispersion.

14. A method according to claim 11 characterized in that said one or a plurality of vessels are moved automatically subject to a central control.

15. A method according to claim 11 characterized in that said vessels are moved by conveyor.

16. A method according to claim 11 characterized in that said one or a plurality of vessels are raised into position at said one or more preparation stations.

26. A method according to claim 11 characterized in that said one or a plurality of vessels are moved by conveyor.

21. A method for supplying liquid to one or more pieces of apparatus characterized in that one or a plurality of vessels visit one or more preparation stations until the liquid is prepared and the liquid when prepared is continually supplied to the apparatus in batches by said one or a plurality of vessels, the rate of liquid preparation and the vessel movements being matched to the requirements of each preparation station.

22. A method according to claim 21 characterized in that the liquid being prepared is a coating dispersion.

23. A method according to claim 21 characterized in that said one or a plurality of vessels are moved automatically subject to a central control.
