Abstract
An orbiting platform mixer having a reversing cycle of operation. In response to input signals defining set points for the platform velocity, the mixing cycle time and the reversing period, a control commands a reversing cycle of a rotation of the orbiting platform in one direction at the at the platform velocity for the rotation period. After a pause, the control commands a rotation of the orbiting platform in the opposite direction for the rotation period; and the above reversing cycle is repeated for a period of time equal to the mixing cycle time. The control permits the input signals to be changed at an accelerated rate in response to the continued single state, that is, pressed state, of a push-button.
