Abstract
Abstract Method of and apparatus for emulsification of oils assuring obtaining the desired dispersion and stability of emulsions. Vibration action is applied to cells containing water and oils so as to subject the cell and their contents to energy impulses varying in accordance with sine curves, thereby dispersing oil into fine drops which are evenly distributed throughout the system. The apparatus includes a plurality of serially mounted emulsion cells forming a unitary closure, the closure being mounted on a fixed support through springs. A vibration device is mounted upon the enclosure so as to vibrate it as described. Between the successive cells in the enclosure there are disposed grids or sieves, and vibration actuated valves having valve elements which function somewhat in the manner of diaphragm pumps.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A method of emulsification of oil and water comprising introducing a mixture of water, oil and air into a first, mixing cell, passing such mixture through a perforated plate into a second, emulsion cell, and subjecting the water-oil-air medium in both the mixing cell and the emulsion cell to a vibration action having a frequency of 10-200 Hz and an amplitude of 0.1 - 9 mm, the water-oil-air medium being subjected to mechanical shock by impulse-actuated reciprocating valve elements disposed adjacent said perforated plate and functioning as diaphragm pumps to suck the medium through the openings in the plate said cells being sealed off from each other by said valve elements when the latter are not vibrated.
Claim 2
Independent Claim
117 words
A method of emulsification of oil and water comprising introducing a mixture of water, oil and air into a first, mixing cell, passing such mixture through a perforated plate into a second, emulsion cell, and subjecting the water-oil-air medium in both the mixing cell and the emulsion cell to a vibration action having a frequency of 10-200 Hz and an amplitude of 0.1 - 9 mm, the water-oil-air medium being subjected to mechanical shock by impulse-actuated reciprocating valve elements disposed adjacent said perforated plate and functioning as diaphragm pumps to suck the medium through the openings in the plate said cells being sealed off from each other by said valve elements when the latter are not vibrated.
Claim 3
Independent Claim
105 words
An apparatus for the emulsification of oil, comprising an enclosure containing serially-disposed cells the first of which is a mixing cell and the second of which is an emulsion cell, the enclosure being supported by springs, a vibrator mounted upon the enclosure, a perforated plate and at least one valve element spanning the enclosure and forming the boundary between successive cells and guide means permitting the valve element to move through a limited vertical path between its lower, completely-closed position and its upper, completely-open position said valve element remaining in its completely-closed position when said enclosure is not being vibrated by means of said vibrator.
Claim 4
Independent Claim
105 words
An apparatus for the emulsification of oil, comprising an enclosure containing serially-disposed cells the first of which is a mixing cell and the second of which is an emulsion cell, the enclosure being supported by springs, a vibrator mounted upon the enclosure, a perforated plate and at least one valve element spanning the enclosure and forming the boundary between successive cells and guide means permitting the valve element to move through a limited vertical path between its lower, completely-closed position and its upper, completely-open position said valve element remaining in its completely-closed position when said enclosure is not being vibrated by means of said vibrator.
Claim 5
Dependent Claim
33 words
Apparatus according to claim 2, further comprising balls contained in the successive cells, such balls being subjected to mechanical vibration imposed thereon by the vibrator and improving the emulsification of the water-oil medium.
Claim 6
Dependent Claim
37 words
Apparatus according to claim 3, further comprising a plurality of medium-feeding pipes connected to the lower end of the lowermost, mixing cell, and at least one discharge conduit to the upper end of the uppermost, emulsion cell.
