Abstract: A system for controlling heat delivery including at least one heating element to generate heat, at least one power regulating device to regulate the amount of energy output to the at least one heat element, at least one monitor device to measure environmental parameter data of the at least one power regulating device and the at, least one heating element, a data processing computer to process environment parameter data from the at least one monitor and initial setting data and provide operating instructions, and at least one control device to receive the operating instructions from the data processor and control the at least one power regulating device to regulate energy output to the at least one heating element.

Abstract: Method and apparatus for measuring the weight per unit area and providing cross-sectional, longitudinal, and diagonal profiles of density or thickness of moving manufactured sheet products. The apparatus comprises a stationary radiation source, an array of detectors, and electronic means for processing the signals from the detectors to obtain a total cross-sectional, longitudinal, and diagonal profile of density or thickness of moving manufactured sheet products. The energy output of the radiation source remains constant during a measuring operation. The apparatus utilizes a line-up of individual radiation sources delivering constant radiation. Each individual radiation source generates an equal amount of radiation. The radiation transmitted from the individual radiation source is intercepted by a detector/electronic assembly after penetrating the sheet product. The detector/electronic assembly converts the intercepted radiation to electric signals.
