  • Modified heat chamber and method to improve heat cycle efficiency using airflow control
    Patent number: 9145898
    Abstract: The present invention relates to improvements in the art of operating large heat chambers so as to reduce both the time and the cost required for heating materials. More specifically, the modified heat chamber of the present invention provides a programmable control mechanism capable of significantly reducing areas with temperature variations or hot and cold spots. A programmable heat chamber leads to significant reductions in the required processing time and in the cost of the required energy.
    Type: Grant

  • Thermal agglomeration of toner in laser cartridges to aid recycling
    Patent number: 8644727
    Abstract: A low cost batch or continuous toner agglomeration process for laser printer toner cartridges that virtually eliminates generation of airborne toner and that provides associated health and safety benefits. The residual powdered toner in cartridges is solidified in a clean, low cost thermal agglomeration process.
