  • APPARATUS WITH MULTIPLE HEATING SYSTEMS FOR IN-LINE THERMAL TREATMENT OF SUBSTRATES
    Publication number: 20120085281
    Abstract: The present invention relates to in-line equipment used to process substrates. In some applications, the equipment is used in the in-line manufacture PV cells or modules. In some embodiments, a heating system is provided that comprises a plurality of heating technologies for the heat treatment of substrates wherein a first heating system is used to rapidly raise the substrate temperature to the desired set point and a second heating system is used to maintain the substrate at the temperature set point throughout the thermal treatment process.

  • High accuracy in-situ resistance measurements methods
    Patent number: 7825672
    Abstract: Methods to determine an instantaneous resistance value of an electric circuit and a measurement system to determine an instantaneous resistance value of an electric circuit are disclosed. Exemplary embodiments of the method measure an in-situ instantaneous voltage of the circuit and an in-situ instantaneous current of the circuit and calculate the instantaneous resistance. Optional temperature measurement can be included in the method and the calculated instantaneous resistance related to the measured temperature. The method can be applied to phase angle fired loads and to zero-cross (time proportioned) loads.

  • Magnetic field reduction resistive heating elements
    Patent number: 7335864
    Abstract: Heating element assemblies, heating furnaces incorporating heating element assemblies, methods to form heating element assemblies, methods to form heating furnaces and methods to reduce a magnetic field in a bifilar coil are disclosed. The heating element assembly includes two components, each component formed from heating element wire. The two components are spatially positioned and electrically arranged, relative to each other, so that an electrical current applied to the heating element assembly simultaneously travels through the two components in opposite directions.
