To all whom it may concern:

Be it known that I, FRANZ MAX' BER- anmcn, chemist, a SIIbJecb of'the German Emperor, and resident of No. 8 Zastrowstrasse, Kiel, German ,have invented certain. new and useful mprovements in Devices for Mixin and Rendering Liquids Homogeneous,

This invention relates to a device for the mixing and rendering homogeneoiis of liquids, and" more particularly adapted for the treatment of. milk in order to counteract the separation of cream therefrom. To this end the liquids are torced through one or several adjustable passages after which ecreasing pressure" as to be caused to return and to meet the on-coming liquid in a counter-current.v

In order to effect this use may be made of a simple cylindrical body, which 'is'inserted in a casing so as to form with this casing an'adjustable passage, all parts of the structure being stationary when in operation. Around this passa e a roove is arranged in the casing, in w ich t e liquid after traversing the passage, penetrates and then' returns and is discharged. In the lace of one simple cylindrical body a comination of several in the form of a conical stepped body may be used in which case the pressure of the liquid gradually decreases from the apex of the cone to the base. The. current of li uid is then so guided that after each exit rom the passage formed by one step and its seat, it enters the adjacent groove, after which it returns and is forced in the counter current to the next step, at which the same operation is repeated. In this vmanner the 1iqu1d is rendered homogeneous to a greater degree than is-the case with the known processes, in which a pressure of 150 and more atmospheres is employed as against a considerably less pressure employed according to the present method. The result is adbetter 0 which the following is a a body thin liqui Application filed October 11, 1912. Serial 1%. 725,114.

stepped fillin body. Fig. 2 is a section on the line A- of Fi 1 and Fi 3 shows another form of the evice provi' ed with a cylindrical filling body. 7 f According to Figs. "1 and 2 the device consists of a rectangularly bent tubular portion a provided with a passage 6 and connected to a casing c, the central passe e d of which coincides withthe passage 6. lhe casing c is provided with a cavity having a stepped forward and a cylindrical rearward portion. Flush with the step ed parts or shoulders e of the casin a are ormed within the casing 0, a plura ity of laterally extending grooves f, that open at their inner ends-into the central cavity of said casin while they are closed along their outer en s -to form whatmay be termed a series of ;blind alleys. Arranged in the cavity of the casing c is a normally stationary body or filling piece 9 which islikewise provided with stepped parts so arranged as to form with the casing c annular spaces h. These annular spaces It cannot be varied whereas the stepped portions 2' on the body 9 and the shoulders e of the casing c are capable of being adjusted with the aid of a spindle is, to such an extent that only extremely narrowpassages remain between them. The moreover is provided with ducts Z. Attac ed to the casing c is a bent pipe m in which the screw spindle is is guided, and

which is provided with a discharge passa e n.

The liqfiid to be treated and admitted through t e pipe (1 is forced through the passages b-d into the casing c, by way of the fine passages between the shoulders e and steps 1' entering the grooves f in the form of a thin sheet, which by the edges in these spaces is deflected downwardly and caused to return until it reaches the annular spaces It whence it is forced in a fine sheet between the next following step portions of the casing and of'the body g, into the next grooves f, and so on until the liquid is discharged through the ducts l and the passage 11. P

By the o eration described, the extremely p sheet entering under pressure any one of the grooves f is forced to return within said groove as it can flow outwardly only until 0 ecked by the. outer closed end thereof. In this way the inflowing current is caused to meet the outfiowing current within the groove, whereby a frictional conduced. The end of this tact between the liquid particles is obtained which efiects the desired homogeneity of the liquid.

According to Fig. 3 the device is,pro-" vided with a cylindrical. filling piece or, body 0 connected to or extended to form a which the liquid is ultimately discharged through the socket u.

What I claim is 1. A device for rendering liquids homogeneous comprising a casing having a liquid inlet, a cavity and a liquid outlet, a body arranged withm said cavity to form a passage therebetween, the casing being provided with a laterally extending groove that is closed at its outer end and opens at its inner end into said passage, all parts of the structure being stationary when in operation.

2. A device for rendering liquids homogeneous comprising a casing having a liquid lnlet, a cavity and a liquid outlet, a body arranged within said cavity to form a liquid passage therebetween, means for adjusting said body and thereby adjusting the liquid passage, the casing being provided with alaterally extending groove that is closed at its outer end, and opens at its inner end into said passage, all parts of the structure being stationary when in operation.

3. A device for rendering liquids homogeneous comprising a casing provided with a stepped cavity, the step portions of the casing terminatin 1n annular grooves, and

a stepped adjusta 1e body arranged within the casin with which it forms annular spaces ad acent to the grooves, all parts of the structure being stationary when in operation.
