A method for controlling a discharge plasma-based radiation source for stabilizing a radiation dose emitted in a pulsed manner is disclosed. The catalyst uses \u03b1-Al2O3 as a carrier and is nano-porous. A fireproof barrier is disposed between the grease absorbing pads and the roof. The control signal may also be variable in strength wherein the orthotic joint provides increasing or decreasing resistance to motion responsive to a corresponding increase or decrease in control signal strength. When the passive conveyor is fully occupied with semi-manufactured products, the active conveyor pivots to a position in alignment with the curved slide, so that unneeded semi-manufactured products slide out along the curved slide.
