  • Temperature control system for glass sheet furnace
    Patent number: 4807144
    Abstract: A temperature monitoring and control system for a glass sheet processing system includes a temperature sensor mounted at a preselected location in the system, a display, and a computer connected to the temperture sensor for periodically receiving a series of signals corresponding to temperature values transmitted by the sensor. The computer includes memory for storing selected values received from the temperature sensor and memory for storing one or more preselected threshold values. The computer also includes control logic for comparing the temperature values with one or more of the preselected threshold values, selecting and storing a set of those temperature values which satisfy a predetermined criteria, and displaying the set of temperature values as a profile taken along the length of the glass sheet in the direction of conveyance of the sheet through a glass processing system.
