Definitions

  • the invention relates to a method and an apparatus for the preparation of liquid mixtures.
  • the invention is particularly, but not exclusively, concerned with the preparation of dilute solutions of concentrated liquids and a diluent, but it should be appreciated that it can be used where mixtures of miscible liquids are required.
  • an apparatus for use in preparing liquid mixtures is proposed, as described in claim 4.
  • a supply of treatment liquid and replenishing liquid can be prepared without the user having to carry out any dimensions with one or the other of these liquids.
  • the standard amount of the first liquid can be supplied to the user as a bottle or the like, which is filled with the standard amount of liquid.
  • the second liquid can then be introduced into a mixing-preventing device until the time when the second container is wordsn filled to the required level.
  • the second liquid is fed to the anti-mixing device and then flows first into the first container to fill it and then flows over and over an overflow at the top of an extension tube and down to fill the second container which is filled with one Display can be equipped, which indicates the reached filling level and possibly interrupts the inflow of the second liquid.
  • extension tube pieces of different lengths can be provided, as mentioned in subclaim 7, and the height of the display can be adjusted.
  • the device comprises a trough or tank 1, which is advantageously made of plastic and is divided by a partition 2 into a first or refill container 3 and a second or treatment container 4.
  • the outflow pipe 5 is connected via a feed pipe 8 to an inlet 7 in the base wall of the treatment container.
  • Another outlet in the base wall of the container is connected via a feed pipe 10 to a pump 11, which in turn is connected to a pipe 12 leading into the upper end of the treatment container 4.
  • a rotatable drum 13 is mounted on bearings (not shown) in the side walls of the treatment tank and is engaged by three guide rollers also mounted in the side walls.
  • sheet material is passed between the rollers 14 and the drum 13 and through a bath of treatment liquid contained in the container 4.
  • the device is particularly suitable for the treatment of photographic material, wherein a developer, fixing or the like treatment liquid is used in the treatment container and a solution of the same treatment liquid, but usually of different strength in the refill container.
  • a developer, fixing or the like treatment liquid is used in the treatment container and a solution of the same treatment liquid, but usually of different strength in the refill container.
  • it has previously been customary to measure two different amounts of the concentrated treatment liquid, to dilute them with different amounts of water and then to pour them into the relevant containers.
  • Concentrated development solutions that are extremely caustic are very often used, while concentrated fixative is acidic and contains sulfite ions that act as reducing agents. It would therefore be highly advantageous if it was no longer necessary to measure different amounts of one or the other of these concentrated solutions.
  • the diluted solutions can now be prepared in a simple manner, without the need to measure the concentrated liquids in question separately.
  • a certain amount of concentrated solution is poured into the container 3.
  • the liquid then fills the container to the level of the overflow 6 and further liquid then flows through the pipe 8 into the container 4, for example to fill it up to the height h 2 , as shown in FIG. 1.
  • the base areas of the containers 3 and 4, the height of the overflow 6 above the base area of the container 3 and the predetermined amount of concentrated liquid are chosen so that when the containers 3 and 4 are subsequently filled with water or another diluent up to a prescribed level, the resulting solutions in the containers have the required concentrations.
  • the device in such a way that when a two-liter normal bottle of concentrated liquid is poured into the container 3, the containers 3 and 4, as shown in FIG. 1, are filled to the levels h 1 and h 2 , respectively , so that when the containers are subsequently filled with water up to the levels h 3 and h 4 , as shown in FIG. 2, solutions of the required strength are obtained.
  • the containers can be filled such that the level of the liquid in each container is the same and just above the outlet 6, and that the height of the liquid in the container 4 is the same or less, but never can be more than the height of the liquid in the container 3.
  • a tubular hollow standpipe 15 is placed on the outlet to increase the level of the overflow from the container 3 to the end 16 of the standpipe.
  • One end 17 of the standpipe is secured by a tight fit and the other or upper end of the standpipe 15 is surrounded by a cup-shaped vessel 18 provided with an outlet 19.
  • Water or another dilution liquid is now introduced into the cup-shaped vessel 18 from a water supply pipe 20 controlled by a tap or valve 21. The water then flows into the cup-shaped vessel and out through the outlet 19 until it fills the container 3 up to the level h 3 equal to the height of the outlet end 16 of the standard tube.
  • the water flows through the outlet 16 of the standard pipe, through the standard pipe 15, the outlet pipe 5 and the feed pipe 8 into the container 4 until the latter is filled to the desired height h 4 , whereupon the water supply is switched off .
  • the height h 4 can be the same or less than the height of the liquid level in the container 3, but never greater.
  • the water supply can be switched off as soon as the user sees that the level in the container 4 has reached a certain mark, but the container 4 is preferably equipped with a liquid level indicator 22.
  • a simple float switch as shown in FIG. 3, in which the float switch 22 is connected in a circuit with display means such as the bell 23 or the warning lamp 24, one or both of which are provided to the Warn users that container 4 has been filled to the required level.
  • Fig. 3 also shows that the float switch can be used to control the valve 21 and can interrupt the water supply as soon as the container 4 to required level has been filled.
  • a number of standpipes 15 of different lengths can be provided and the height of the float switch 22 above the base of the container 4 can be adjusted so that by suitable selection of a standpipe and adjustment of the Switch the strength of the two solutions can be changed.
  • the two containers can be separate from each other, but this is not so advantageous since problems may arise when setting up at different levels or levels.
  • this configuration can be useful if the containers are in fixed positions, since this enables the refill and treatment solution to be prepared in a refill tank that is at a distance from the treatment site, which is particularly advantageous if the operation at the treatment site is used to generate dangerous or harmful fumes.
  • the outlet pipe 5 can be provided in a side wall of the container 3, provided that its overflow outlet 6 can be covered in a liquid-tight manner by a standpipe of a suitable shape.
  • FIG. 4 A particularly preferred modification of the device is shown schematically in FIG. 4.
  • the device shown in FIG. 4 comprises a first or refill tank 33 for refilling developer solution, which is connected to a second or development tank 34 via a feed pipe 38 and feed pipes 310 and 312 and a pump 311.
  • the device further comprises a first or refill tank 43 for fixers, which is connected to a second or fixer tank 44 via a feed pipe 48 and feed pipes 410 and 412 2 and a pump 411.
  • the first two tanks 33 and 43 are arranged side by side, while the developing tank and the fixing tank are arranged so that photographic material is passed first through the developing tank and by means of rotatable drums, not shown in Fig. 4, but the same as those in Figs 1 and 2 are shown, can then be passed through the fixing tank.
  • the device according to FIG. 4 represents an impressively simple device for preparing and using developing and fixing solutions for photographic material.
  • the present invention is primarily concerned with the preparation of photographic processing solutions by diluting concentrated liquids with water, the invention is of course more widely applicable and can be used to prepare other mixtures of miscible liquids in desired concentrations.
