Abstract

In a preferred embodiment, there is an electronic comparator that monitors and exhibits on one or more video displays current information measured and monitored as to physical attributes relating to a revolvably rotating linearly-extending stirring shaft of which a distal end carries stirring blades positioned within media supported within a vessel stably mounted relative to a stably mounted drive mechanism and the stirring shaft, and a visual display video that during stirring displays visually the measured and monitored current degree of wobble of the stirring shaft, magnitude of vibrations of the stirring shaft, current degree of verticality of the stirring shaft, current temperature of media being stirred by the stirring shaft, current rate of revolutions per unit of time of the stirring shaft, a printing mechanism that prints current measured and monitored physical attributes onto a substrate, a computer interface structure and mechanism thereof adapted to convey measured and monitored physical attributes to one or more computer units and/or video monitors and/or printers thereof, and mounting structure for establishing and maintaining stable mounting and ascertained relative predetermined and established positioning to one-another of the stirring shaft'"'"'s rotary drive structure and mechanism thereof, the stirring shaft, the vessel and the monitoring and measuring mechanism and structure thereof, during agitation of media by the blades on the distal end of the stirring shaft.
