Abstract
The use of ultrasound or acoustics applied at a level below that which causes cavitation to control the energy balance between particles and the liquid phase in a metastable liquid.
Claims28
A process for the control of crystal formation comprising applying ultrasound or acoustics at a level below that which causes cavitation, including stable cavitation and transient cavitation, to a metastable liquid to thereby control the energy, mass balance, or both between particles and a liquid phase in the metastable liquid.

A process for fractionating a triglyceride fat or oil, which comprises the steps of:
- a. when the triglyceride fat or triglyceride oil is solid, heating the triglyceride fat or triglyceride oil until no substantial amount of solid triglyceride fat is present in the triglyceride oil,
- b. allowing the triglyceride oil to cool and to crystallize and controlling the crystallisation by exposing the cooling fat to selective ultrasound or acoustics resulting in a solid fraction,

A process comprising de-tempering of chocolate melt during re-work by the application of ultrasound or acoustics power which melts crystal nuclei produced in the tempering operation without heating a liquid oil suspending phase.
-26. (canceled)
A fuel system such as a fuel tank, a fuel tank take-off chamber, or a fuel delivery line close to a location of a feed of fuel to a diesel engine or a heating boiler containing a source of ultrasound.
