  • Apparatus for dissolving a solid material in a liquid
    Patent number: 7300197
    Abstract: An apparatus for dissolving a solid material in a liquid including a container for receiving the solid material and the liquid. A turbidimeter measures the turbidity of the liquid in the container. A blender stirs the liquid in the container until the turbidity thereof, as measured by the turbidimeter, falls below a predetermined level. A sensor gauges the level of liquid in the container and causes a valve to admit liquid into the container when the liquid level falls below a set point.

  • Method for dissolving a solid material in a liquid
    Patent number: 7282101
    Abstract: A method for dissolving a measured quantity of a solute in a solvent. First, a tracer is combined with a solute in known proportions to form a mixture. The tracer is capable of increasing the turbidity of a solvent in proportion to the concentration of the solute dissolved in the solvent. Then, a container is provided for receiving the mixture and the solvent. Next, the solvent and the mixture are introduced into the container. Finally, the solvent is stirred until its turbidity reaches a predetermined level.
