The present invention may be embodied as a compounding system having a chamber assembly defining a working chamber; a shaft, a sleeve assembly, and a plurality of arms. A plurality of actuators project from the working surface. The gain compensator compensates for the variable VCO gain by generating a charge pump reference current that is based on the same capacitor control signal that controls the fixed capacitors in the LC circuit. The one or more promotional deals are displayed on a portion of the screen of the television for viewing by the viewer. 95% or more, and an iodine content of 17. A computing unit may be configured to compare the sensor signal to a predetermined function for determining the incidence angle of the ion beam.
