  • Aqueous size composition with pH regulator
    Patent number: 4656084
    Abstract: Aqueous sizing compositions for glass fibers, comprising both epoxy- and acrylyl- or methacrylyl-functional organosilanes together with fiber-forming polymer and lubricant and pH regulator in a defined amount, are particularly suitable for glass fiber reinforcement for filament winding and pultrusion applications. The use of the pH regulator in the defined amount results in a strand tensile strength of significant improvement.

  • Methods of measuring temperature and electrical resistivity in a molten glass stream
    Patent number: 4603980
    Abstract: A small sensor electrode with only the tip exposed is used with a much larger return electrode to complete a high frequency circuit through molten glass. The sensor electrode is calibrated in the laboratory and then used to measure the resistivity of the molten glass. This sensor electrode consists of a type R thermocouple with which one can also measure the temperature of the thermocouple junction. Thus one can measure both the temperature and the resistance at a common point. These measurements are used to monitor the molten glass system.
