V INVENTOR. JEAN PATHUS LABOUR Patented Oct 21, 1952 Jean Pathus Labour, Washington, D. 0., assignor to Gasoline Research Industrial & Commercial Company, Inc., Panama, Panama, a company of the Republic of Panama Application April 9. 1948, Serial No. 20,160 In France August 13, 1947 7 Claims. (01. 251 -18) This invention relates to an apparatus for forming relatively small particles .of a liquid having a relatively high viscosity, whichparticles are of substantially uniform shape and size. Such an apparatus is particularly useful, for

example, in forming such particles ofthe emulsion obtained from dispersing liquid hydrocare bons within suitable aqueous colloidal solutions,

which emulsions are utilized. in various processes for the preparation of solids containing dis-' persed liquid hydrocarbons, such as gasoline. An apparatus for carrying out a process of this type has been disclosed, for instance, in the French patent application Prov. No. 540,686, filed in France on August 13, 1947, now Patent No.

952,045 dated April 25, 1949, in the names of the present applicant and Berthier. the same subject matter has also been disclosed in the United States atent application made in the name of the present applicant bearing Serial No.20,154, filed April 9, 1948, now Patent No.

The apparatus disclosed in the above applicaa r 2 is particularly well adapted for use'where it is desired to operate a number of such devices with one common control member. 1

Still another object of the invention is to provide an obturator which is reliable and positive Substantially tion; and,

tions includes a solidifying mechanism which comprises among other components a plurality of containers disposed in vertical spaced relation. The uppermost container is adapted to receive the emulsion to be solidified and is equipped with a perforated bottom which is characterized as having suitable obturators associated with the perforations therein. These obturators are adapted to be operated by a common control mechanism so that drops of the emulsion may be formed and allowed to enter the second container which contains a bath of suitable solidifying reagent. No specific disclosure was made, however, in either of the above mentioned'applications of the exact construction of the type of obturator to be used. l

It is, therefore, an object of the present invention to provide an obturator suitable for use in such an apparatus.

It is an additional object of this invention to provide an obturator of the character described which is useful, generally, in the formation of relatively small particles of uniform shape and size, of a liquid having a relatively high viscosity. i

It is a further object of this invention to provide an obturator which is particularly adapted to form such particles when disposed in close simple in both operation and construction and ments shown in Figure 4.

association with an. orifice in a plate member, or

-segments are shown in their maximumposition in its action and which can be utilized to produce uniform particles of varying shapes, such as cylindrical or spherical, with the same desirable accuracy.

"Further objects and advantages of this invention will become evident as the description proceeds and from an examination of the accompanying drawing which illustrates one embodiment of the invention and in which similar numerals refer to similar parts throughout the several views.

In the drawings- Fig. 1 is a plan view of one form of obturator embodying the subject matter of this invention,

the device being shown in the fully opened posi- Fig. 2 is a plan view of the obturator shown in Fig. l, the device being shown in the fully closed position.

Figure 3 is a somewhat fragmentary view in horizontal cross section of the obturator shown in Figure 1; l i

Figure 4 is a plan view of an alternative form of obturator embodying the invention, which has segmental plates the normal position which may be adjusted as desired;

Figure 5 is a view in elevation of one of the pivot posts carried by the freely movable seg- Referring now to Figs. 1 and 4, the obturator may include two fixed segments 10 and 12 upon which similar segments l4 and 16 are adapted to slide. These segments may be in the form of sectors of an annulus, as shown, which sectors are in concentric relation to the opening '19 in l r the bottom ll through which the liquid to be divided passes. The normally fixed segments 10a and lZa shown in Figure 4 are adjustable so that they may be moved toward or away. from each other and secured in any desired setting. This adjustment is accomplished by the set screw l3 disposed in the slot I5 in the tongue ll on each sector Illa and [2a as shownin Figure 4. These 3 of outward adjustment in Figure 4. Since the segments I and I2 and Illa and l2a and the overlapping segments l4 and I6 are so designed to form the substantially circular opening I8 when in the maximum positions shown in Figure 1 and Figure 4, respectively, any setting of the segments I0 and I2 which moves them inwardly toward each other will tend to restrict the size of the opening I8. By such adjustment of the position of the segments Illa and IZa, the size of the particles formed by the normal operation of the obturator, wherein segments I4 and It only are moved, may be varied.

I which the opposite ends of these arms are piv- Since the paths of movement of segments I4 and it may also be made capable of adjustment, as explained below, the size of the particles formed by the obturator may also be controlled in this manner. In other words, means may be provided for adjusting the outward movement of the segments I4 and 16 so that they will not be able to move to the maximum position shown in Fig. 1. Such a restriction'of the movement of the segments I4 and I6 will tend to restrict the size of the opening I8 as shown in Figure 4 and will, therefore, restrict the size of the particles formed.

The movement of the segments I4 and I6 may oted to move inwardly, or to the left, as the device is represented in Fig. 1. If the arm 46 is moved a suflicient distance in the manner described segments I4 and I6 will be moved into an overlapping relationship and will eventually assume the position shown in Fig. 2, which position completely closes the opening I8. In order I to insure the proper overlapping action of the segments; I4 and I6 when they are moved together the two segments are normally disposed in two parallel planes and the leading edges of each may be slightly beveled on opposite sides so that when the segments overlap one of these edges will be slightly displaced relative to the other. It should beunderstood, however, that the disposition of all of the various segments of the obturator is such that when the position shown in Fig.2 is assumed, they form a substantially impervious barrier to the. passage of a liquid.

Obviously when the 'arm 46 is moved in the opposite direction, starting from the position of adjustment shown in Fig. 2, the action described above will be reversed and, when the arm 46 has been returned to the position shown in Fig. 1, the various segments of the obturator will again be disposed substantially as shown in Fig. 1. This cycle may be repeated as often as desired so that by reciprocal movement of the arm 46 the opening I8 can be alternately opened and closed. If. the obturator is to be used in an installation such as that described in the applications above I identified, such a reciprocal movement of the to the bottom I I by the holding member 35. The

shaft 36 also has one end of the arm 36 pivotally mounted thereon, the opposite end of this arm being pivotally secured to one end of the segment IE on a pivot post 23.

In substantially the same fashion, one end of the arm 28 is pivotally secured to the other end of the segment I4 and the opposite end. of the arm 2% is pivotally secured to a shaft 38. The

shaft 38 is mounted to slide in the slot/It of the fixed supporting member 42 and one end of the arm 44 is pivotally mounted on the shaft 38, as

best shown in Figure 3, while its opposite end is pivotally secured to the end of segment I6 opposite the end to which the arm 36 is secured.

Such an arrangement allows the segments I4 and it to be simultaneously moved together, as shown in Fig. 2, by proper operation of the arm 46, which arm cooperates with the rod 20. If this movement of the arm 46 is to the right, with respect to its position shown in Fig. l, the rod 26 and the arms 22 and 24 will be moved in the same direction, carrying with them the segment I4. As the segment I4 moves inwardly or to the right as shown in Fig. 1 the ends of the two arms 26 and 26 secured to this segment are also moved to the right. Since the opposite ends of the arms 26 and 28 are secured to the shafts 30 and 38, respectively, which shafts are confined within the vertical slots 32 and'40, the movement to the right of the ends of the arms 26 and 28 secured to'the segment l4 will cause the opposite ends arm 46 will successively cut the thick or pasty liquid which is adapted to pass through the opening 18, and the liquid will therefore be divided into uniform sections of regular shape, which sections may then be permitted to fall into a suitable solidifying bath.

If desired, as shown in Figures 4 and 5, the pivotal mounting 23a for the ends of the arms 26a and 28a on thesegment I4 may be made so that the ends of the arms 24a and 22a may be secured at any desired point to the pivotal mountings 23a. Such an adjustment in the position .of these arms 24a and 22a with respect to the pivotal mounting 23a. and the segment I4 will produce modifications in the path of movement of the segments I4 and [6 for the same move ment of the arm 46, as mentioned above, which may be used as one method of controlling the size of the particles formed by the obturator. An opening 25 may be provided in the p s s 2311 to receive the arms 22a or 24a and a thumb screw 21 can be utilized to secure the arm 22a or 24a, in the selected position as shown in Figure 5.

Although the specific embodiment illustrated has been shown with only two normally mobile segments, it should be understood that there could be a greater number of such segments utilized. In addition, it should be specifically pointed out that obturators of the construction disclosed are particularly adapted to being operated by a common control mechanism. The arm 46, for instance, could be one of a plurality of similar arms secured to still another arm dis-' posed substantially at right angles to the-arm 46. Such an arrangement might be desirable,

for instance, in the type of apparatus described I in the above identified applications.

In the drawing and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they. are used in a generic and descriptive si a sense emyaiie not-"roe purposes of -limitation} the scope of the invention being defined in the claims."
