  • Patent number: 5814232
    Abstract: Vibrational energy is introduced into a portion of a liquid-solid work mixture at a natural resonant frequency of that portion of the mixture while that portion of the mixture is in a fluid or semi-fluid state. A vibrating apparatus imparts controlled vibrations either onto the surface or beneath the surface of the liquid-solid work mixture in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to an increase in the natural resonant frequency of the progressively-narrowing liquid portion at the top of the liquid-solid work mixture. A resonant frequency-indicative condition of the liquid portion of the work mixture adjacent the vibrator apparatus is sensed as the vibrator apparatus moves across the top surface of the liquid-solid mixture, and the output frequency of the vibrating apparatus is correspondingly adjusted in accordance with the sensed condition as the vibrator apparatus travels.
