Abstract: For the continuous mixing of fluid process materials or gases as they flow uninterrupted from a point of initial mixing to a discharge end and processed by means of intense vaporous cavitation, use is made of a resonant tube section having an entrance end and an exit end. The tube section is isolated from the rest of the supporting structure by means of resilient isolation mounts. A source of sinusoidal energy is connected to and excites the resonant tube section into one of its modes of natural frequency causing intense resonant sinusoidal acoustic energy to be developed and transmitted in spherical fashion from the inner resonant tube wall and throughout the flowing fluids. The energy thus released generates intense acoustical vaporous cavitation energy which breaks the surface tension and mixes the materials.

Abstract: Agitator for nonhomogeneous materials held in a tank. The agitator here in question is particularly intended for use with mixed liquid and solid materials, the solids thereof being of easily damaged nature and wherein the liquid and solid components of the mixture tend to separate. The agitator is thus intended to maintain the materials in a thoroughly mixed condition and to move same lengthwise through a tank to the outlet thereof and yet to do so with minimum physical damage thereto. The agitator of the invention comprises a relatively narrow blade arranged spirally for rotation about an axis positioned in the lower part of a horizontally aligned tank, the blade thereof being either perpendicular or inclinedly positioned with respect to the imaginary cylinder enclosed thereby. If inclined, the outer edge of the blade leads the inner edge as same rotates. The agitator can also be used in vertical alignment if desired and used with or without a central shaft.
