Ultrasonic mixer for paints and emulsions

In this paper a device for mixing various sedimented paints and other viscous fluids is described. The action principle of the device is based on the cascade concentration of ultrasonic flexural waves and next their conversion into longitudinal waves in mixed medium. Finally, the acoustical energy is focused along the linear focus inside the mixed liquid medium and results in producing a steep gradient of acoustical pressure which causes movement of the liquid. The opening of paint containers or their shaking is not necessary. This device can also be applied as a washer, emulgator and other similar purposes
