SUPERSONIC AGITATION Filed March 2, 1948 OSC/LLATOR L J uin 11 INVENTOR.

By BENSON CARLIN aw -k ATTORNEY Patented Dec. 11, 1 951 SUPERSONIC AGITATION Benson Carlin, New York, N. Y., assignor to Sperry Products, Inc., Hoboken, N. J., a corporation of N ew York Application March 2, 1948, Serial N0. 12,617

8 Claims.

This invention relates to the supersonic agitation of materials, particularly liquids. Such agitation has been employed heretofore and it has been determined that very desirable changes can be effected within various mediums provided suflicient supersonic power can be developed. As heretofore employed, only sufficient power has been developed to indicate that very desirable changes could be effected within such mediums, but it has heretofore been impossible to concentrate enough power to determine the full value of such agitation. The indications, as gathered from work previously accomplished in this field, are that among the very desirable changes and results which could be effected, if sufficient power could be developed, are the following: destroy bacteria in order to obtain enzymes; more effective sterilization, mixing ordinarily immiscible compounds; treat metals in their molten state to change crystal structure; homogenize liquids more rapidly and in larger quantities.

It is, therefore, one of the principal objects of this invention to provide a method and means for generating suflicient supersonic power to accomplish the above and other purposes, and in general to provide more supersonic power than has heretofore been obtained by similar means.

It is a further object of this invention to provide a method and means for treating continuously flowing fluids with powerful supersonic energy.

It is another object of this invention to provide a method and means not only for delivering a high degree of supersonic power into a fluid, but also to insure that all portions of the fluid will be subject to the high power supersonic treatment.

It is still another object of this invention to provide a method and means for imparting supersonic energy to a fluid through the walls of a container and to insure maximum transfer of energy from the supersonic vibrator through the the container.

Further obiects and advantages of this invention will become apparent in the following detai ed description thereof.

In the accompanying drawings,

Fig. 1 is a transverse vertical section through an elongated fluid conductor showing one form of my invention applied thereto.

Fig. 2 is a longitudinal vertical section through the Fig. 1 device taken substantially on the line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 1 showing a portion of the container with a modified form of my invention applied thereto.

Referring to the drawings. I have shown this invention as applied to a container such as a pipe I0 having a circular cross section although it will be apparent that certain of the features of this invention are applicable to containers having other sections. Furthermore, I have shown this invention as applied to the case where fluid is adapted to flow continuously through the pipe I!) and be treated with supersonic energy as it flows, although it will be obvious that the principles of the invention will in large part apply also to the case where fluid is stationary within the confines of the container.

As shown, fluid is flowing through pipe l0 and the problem consists in delivering the maximum amount of supersonic energy to all parts of the fluid during its flow through the pipe, and to deliver such energy in sufficient quantity to effect the desirable results outlined in the introduction hereto and which supersonic agitation thus far has only indicated as possible without fully achieving these end results.

For this purpose I mount on the surface of pipe Ill a plurality of electroacoustic transducers i I having their inner surfaces ground to fit closely the surface of pipe i0 so that intimate contact between the inner vibrating surfaces of transducers H and the outer surface of pipe I 0 can be achieved. The center of curvature of quartz crystals II is therefore the same center 0 as that of the pipe [0 and the energy delivered by such crystals will be concentrated substantially in the region of center 0. The transducers H are preferably quartz crystals which may be oscillated in the usual manner from any suitable source of high frequency oscillations.

By the above arrangement it will be seen that the entire energy of the plurality of crystals positioned around the periphery of pipe I 0 will be concentrated in the region of the central axis 0 of the pipe and the liquid in this region will receive the maximum concentrated supersonic energy. The violent agitation of the fluid in this region will set up turbulence so that continuously changing streams of fluid will flow inwardly from the outer region of the interior of the pipe toward the region of the central axis and thus substantially all of the liquid will be subject to the concentrated high intensity supersonic power.

In order to insure that all of the liquid will be subiect to the intense power of the region of the central axis 0, a plurality of concentric rings of crystals such as H and H may be provided longitudinally displaced along the pipe to increase the-turbulence and thus insure the passage of all of the liquid through the region oi, concentrated supersonic power at one or more periods during its passage through the pipe. As many longitudinally displaced bands of crystals may be provided as are found necessary to effect the desired results.

The arran ements shown and described in connection with Figs. 1 and 2 will result in con-- centrating in the region of the central axis 0 such power as the quartz crystals can transmit through the wall of pipe 10. To insure that the maximum amount of energy generated by the cr stals passes through the wall of pipe ID, the following relationships should be established:

(1) The product of the density multiplied by the velocity of the supersonic vibrations in the material should be equal to that of the crystal.

(2) The wall of pipe 10 should be tuned to the frequency of vibration of the crystal, i. e., the wall should be A; of a wave length in thickness. By Formula 1, the maximum transfer of energy is obtained from the standpoint of the material of the container wall; by Formula 2, the maximum transfer of energy is obtained from the standpoint of the dimensions of the container.

In a modified form of the invention as shown in Fig. 3. the crystals l2 may be set into the wall of pine l in place of the material of the wall. In this form of invention theprecautions set forth in Formulas 1 and 2 above are unnecessary becau ethe energy does not have to traverse the wall of wine I 0 but is transmitted directly to the liouid i hin the pine.

Having described m ivention what I claim and desire to secure by Letters Patent is:
