FIGURE 11 INVENTOR CALVIN A. STOGKSTILL Ai TORNEY APPARATUS FOR ADMIXING LIQUIDS IN PREDETERMINED RATIO It is known to employ apparatus of many kinds to dispense concentrates or solutions of various substances, in liquid form, into a second liquid diluent or solution. For example, apparatus of various types are used to dispense fruit juices or sugar syrups, disinfeetants, medicinals and the like into a liquid, such as fresh water or carbonated water,

Liquid mixing devices of such types are most often quite complex, and are generally structured to provide means for metering and proportioning the concentrate or solution within a measured amount of diluent. In such devices, the rate of flow of the concentrate, or solution, and the diluent are proportioned one with respect to the other, thoroughly mixed in predeter mined ratio, and dispensed.

Apparatus embodied by the present invention provides further improvements over these and prior art devices.

Among the objects of this invention are:

To provide a new and improved apparatus which is capable of mixing liquids in predetermined ratio, one with respect to another and dispensing the mixed liquids with accuracy and precision.

To provide apparatus of simple structure, particularly adaptablefor receiving and storing a first liquid concentrate or solution for addition to a second liquid, in predetermined ratios as the mixture of liquids is dispensed on demand.

To provide apparatus particularly adaptable for rapidly metering out a concentrate or solution for addition to a flowing stream, the amount of concentrate or solution added to the stream being directly measured and proportioned in relation to the rate of flow of the flowing stream.

To provide new and durable apparatus of the abovedescribed character for use in addition of concentrates or solutions, particularly fluoridesalt solutions, to drinking water as provided by municipalities to individual residences.

These objects and others are achieved in accordance with the present invention which embodies the combination of an outer vessel constituted of a rigid shell, an inner flexible sac or bag with a nozzle outlet, or opening, and a tubular liquid flow nozzle having a high pressure side and a low pressure side with individual outlets, the said outlet of the flexible bag being communicable to the said low pressure side of the said flow nozzle. The axial opening through the flow nozzle is thus provided with a form of restriction to provide a high pressure side and a low pressure side, and lateral outlets are associated with the high pressure side and low pressure side, respectively. The flexible bag is adapted to contain a concentrate, or solution, particularly fluoride salt solution. The nozzle opening of a filled bag can be operatively communicated with, or connected to, the low pressure outlet of the flow nozzle. The external side of the bag, in operation, is in direct communication with the high pressure outlet, and when a stream of fresh water passes through the nozzle it is split, one portion of the stream exerting pressure upon the external peripheral surface of the bag to force water (because of the differential pressure) through the low pressure outlet into the flow nozzle, while the other portion of the stream which passes through the axial opening of the :flow nozzle picks up the solution, which is admixed or dissolved therewith, and the mixture dispersed as fluorinated drinking water from the flow nozzle.

The invention, and its principle of operation, will be more fully understood by reference to the following detailed description of a specific and preferred embodiment, and to the attached drawings to which reference is made in the description. In the description, similar whole numbers are used to represent similar parts or components, and when numbers. with subscripts are used in common with whole corresponding numbers, the whole numbers are used in the generic sense and subscripts are used where there is a plurality of similar parts or components. Letter subscripts are used to denote a particular part or portion ofa component.

In the drawings:

FIG. 1 is a sectional elevation view showing in detail an assembly of the several principal parts of the preferred device for injecting or adding a solution, e.g., a solution of fluoride salt, to drinking water; and

FIG. 2 is an elevation view taken through section 2- 2 of the preceding figure, showing in further detail the principal parts of the said device.

Referring to the drawings, the principal parts of the device or apparatus can be characterized generally as an outer vessel 10, preferably constituted of a lower container portion 9 and an upper enclosing domed cover 11, conveniently formed in two mating hemi-sections 11 ,11 of substantially equal size. A liquid flow nozzle 20, containing a non-uniform diameter axial opening therethrough which provides a high pressure side 21 and a low pressure side 22, is mounted within the domed cover 11. Outlets 23,24 are connected to the high pressure side 21 and low pressure side 22 of the nozzle 20, respectively. The inlet portion of a flexible bag 30, containing a concentrated solution, can be operatively communicated via suitable connections to the low pressure outlet 24 of the nozzle 20 so that the solution within the bag can be dispersed into the nozzle, picked up, admixed with and discharged with a second stream passing through the nozzle. The contents of the bag 30 are discharged through the nozzle 20 in direct response to external pressure exerted on the peripheral external surfaces of the bag by high pres sure liquid from outlet 23.

A container portion 9 of the vessel 10 is of cylindrical shape and is closed at the bottom so that it can contain liquid. Projecting surfaces 7,8 with horizontally inclined, downwardly facing bottom surfaces are provided to facilitate mounting of the vessel 10 in upright position. This pair of members forms shoulders upon which the vessel can be conveniently supported. The extreme upper portion of the container 10 is generally provided with a removable cover 5, for added strength, and with a circumferential outwardly extending lip or flange 6 upon which the dome-shaped cover 11 can be mounted.

The domed cover 11 is conveniently formed from two mating hemi-sections 11,, diametrically separable one from another, each section constituting substantially a mirror image of the other. Both of hemi-sections 11 ,11 are provided with corresponding external circumferential grooves 12 ,12 and corresponding internal circumferential grooves 13 ,13 which are continuous one set of grooves with respect to another when the two hemi-sections 11 ,11 are joined. Each hemi-section 11 ,11 is provided with diametrically oriented notched portions which form an opening 14 across the diameter of the cover 11 through which the nozzle 20 can be fitted. The inside diametrical edge of hemi-section 11 is provided with a slightly downwardly projected, outwardly extended lip or flange 11 and the inside diametrical edge of hemi-section 11 is provided with an outwardly extended lip or flange 11 these edges forming male and female portions, respectively. These hemi-sections 11 ,11 can thus be fitted together, with the nozzle 20in place, with the lower circumferential groove 13 tightly secured upon the flange 6 to hold the domed cover 11 upon the container 9, and secured in this position by use of the pens 15 ,15 which snugly fit through small diameter openings in the hemispheres 11,,11 provided therefor. The hemi-sections 11 ,11 can be further and more securely held in place by means of a tightly fitted band 16 which lies within the circumferential groove 12, the ends thereof being secured together by a locking device 17.

The liquid flow nozzle 20'is comprised of a tubular member having two different diameter adjoining axial openings 21,22. It will thus be observed that the section of enclosing wall 19 which forms one side of the tubular member provides an opening 22 which is of smaller internal diameter than the relatively larger opening 21 formed by the section of enclosing wall 18 at the opposite end of the tubular member. Lateral openings provide high pressure and high pressure nozzle outlets 23,24, respectively, located within the wall of the liquid flow nozzle 20 and the openings are sized one relative to the other so that a pressure differential exists between the two outlets. The nozzle 20 is maintained in a secure position within the domed cover 11 and it cannot rotate because of the pair of projecting flat-topped lugs 25 ,25 which flush with flat lower edges 26 ,26 of the domed cover 11. A flexible or expandable bag 30, provided with a single nozzle opening 29, capable of containing a solution for injection through the dispensing end 20,, of the nozzle 20, can be operatively communicated, via suitable means, to the low pressure outlet 24.

Suitably, the removable cover 5 is provided with a pair of openings, each containing a short nozzle 33,34. Lines 31,32 are connected through valves 35,36, respectively, to nozzles 33,34. Preferably, the lines 31,32 are flexible or semi-flexible an internally threaded screw caps 37,38, respectively, provide a suitable means of connecting the terminal ends of lines 31,32 to externally threaded nozzles 24,23. The same kind of connections 41,42 are provided, if desired, between the opposite ends of lines 31,32 and the inlet side of valves 35,36, respectively. Similar connections 43,44 are also provided, if desired, between the outlet sides of the valves 35,36 and the nozzles 33,34 within the removable cover 5. The nozzle portion 29 of the flexible bag 30 is suitably attached and held securely in place upon the nozzle 34 by a circumferentially enclosing band 28.

Prior to loading an end 20,, of the nozzle 20 is operatively connected with a fresh water supply to which a solution is to be added. The opposite end 20,, of the nozzle 20 is operatively connected with a source to be supplied with water to which solution is to be continuously added. At the start of loading, there is no flow-of water from nozzles 23, 24 because valves 35,36 are closed, and flow is initiated only on demand as when a tap is opened on the demand side 20 In initiating loading, the flexible or inflatable bag 30 is filled ex situ via its nozzle opening 29 with a solution, e.g., an aqueous fluoride salt solution, to be dispensed and lowered into the container 9. The cover 5 is then brought near the container 9 and the nozzle opening 29 is then fitted over the nozzle 34, and secured in place by the circumferential band 28. The cover 5 is then set in place upon the top of container 9, and screw cap 43 of the line connected to the top of nozzle 34 secured in position on the outlet side of the closed valve 35. Connection is then made between nozzle 33 and the outlet side of valve 36 by tightening down the screw cap 44 which connects the flexible line to the valve. The screw caps 42,38 of line 32 are then tightened down on the inlet side of valve 36 and nozzle 23, respectively. Valves 35,36 are then opened. The hemi-sections 11 ,11 are then fitted together and tightly secured in place about the nozzle 20 and upon the container 9 and tightly secured in place, as described.

In operation, fresh water flows through the axial openings 19,21 of nozzle 20 from a source opposite the direction shown by the open arrows. At outlet 23 the stream of water is split, one portion of the stream flowing through the outlet 23 into the confines of the container 9 while the other portion of the stream flows through the axial opening 22. The water which flows into the container 9 exerts peripheral pressure upon the outer confines of the bag 30 forcing fluoride solution from the bag. The fluoride solution forced from the bag 30 flows through line 31 into the nozzle opening 22.due to the differential pressure, and is picked up by the fresh water which passes through the axial opening 22 so that the water flowing from the dispensing end 20 of the nozzle 20 is fluorided.

The inner bag 30 is gradually collapsed and emptied of fluoride solution. As this occurs, the original volume of the filled bag 30 is displaced by the water which enters the container 9 through the outlet 23. When the bag 30 is empty, it is replaced by another filled bag and the process repeated ad infinitum.

It is apparent that various changes, such as in the absolute or relative dimensions of the component parts, size and shape, materials used, and the like, can be made without departing the spirit and scope of the invention, as will be apparent to those skilled in the art. For example, the specific shape of the axial opening through the tubular flow nozzle to provide the desired pressure differential is subject to considerable variation. Rather than providing two communicating axial openings of differing internal diameters to form high pressure side and low pressure sides, respectively, the axial opening could be in the form of a gradual taper to provide the desired pressure differential. Or, e.g., a restriction such as a perforated plate may be provided within an axial opening of uniform diameter to provide a high pressure side and low pressure side, respectively. What is essential is that a restriction of some sort be provided to create the desired pressure differential. The desired differential pressure per se, on the other hand, is readily determined and provided by well known principles, in connection with water flow rate, to meter the desired amount of solution into the fresh water.

The outer vessel is generallyconstructed of a rigid material such as plastic or metal, e.g., iron, steel, aluminum or the like. The vessel is generally built to withstand a moderately low pressure, e.g., 150 psig. The flexible bag is constituted of a relatively inert or non-reactive material which can be readily filled with a desired volume of solution, and then readily collapsed and emptied by the differential pressure provided Various plastics and plastic-like materials which form staple articles of commerce are suitable for such purpose, e.g., polyethylene, polyvinyl acetate, ethylene terephthalate resin, nylon and the like.

It is apparent that various other changes can be made without departing the spirit and scope of the invention. Having described the invention, what is claimed is:
