Abstract: A moisture metering calibration method and system for, e.g., determining the moisture lumber within a lumber drying kiln is disclosed. Calibration of moisture indicative electrical signals obtained from, e.g., moisture sensing capacitive plates spaced apart within a stack of drying lumber is performed, wherein long lengths (e.g., up to 1000 linear feet or more) of coaxial cable can be used for transmitting the signals, and effectively removing signal anomalies induced in such cabling so that accurate lumber moisture measurements result. Such extended cable lengths provides flexibility with respect to placement of electronic moisture metering equipment. This flexibility allows such equipment to be placed in an environmentally-controlled enclosure, rather than on the weather exposed exterior of a kiln whose lumber is being monitored.

Abstract: A process for curing a natural or synthetic rubber includes the measuring of curing conditions by dielectric or impedance means to produce a process curve (impedance property data versus time) followed by analyzing the process curve with a software algorithm which defines and statistically quantifies the correlation between the process curve and the desired part properties. The correlation relationship is applied in real time to end the curing process at the optimum time and to produce rubber parts of uniform quality and with reduced process cycle time.
