Patent ID: 8007162

Claim:
A self-contained vehicle mounted slurry flow control system, comprising: an aggregate material storage hopper; an emulsion storage tank; a water storage tank; a liquid additive storage tank; a dry additive hopper; a digital positioning receiver consisting of a global positioning system (GPS) or Horn Radar for wirelessly sensing a speed of a vehicle to which the slurry control system is mounted; a hydraulic motor controlling the said aggregate and emulsion flow rate; a liquid additive flow meter, water flow meter and dry additive hydraulic motor; a multiplicity of RPM sensors for sensing the rotation of said hydraulic motors; an adjustable display; a dedicated prime mover and pump; a microcontroller; wherein said microcontroller receives input information from said digital positioning receiver regarding the speed of the vehicle to which the slurry flow control system is mounted; wherein said microcontroller receives input information from said multiplicity of RPM sensors to determine output flow rates of said liquid additive, water, dry additive, aggregate and emulsion; and wherein said microcontroller proportionally adjusts the output flow rates of said liquid additive, water, dry additive, aggregate and emulsion based on the input information from said multiplicity of RPM sensors and said digital positioning system in order to meet a predetermined target flow rate.
