A pair of spaced-apart conductive elements contact opposite ends of the resistance sheet to enable a flow of current through the sheet thereby producing substantially uniform heating over the entire area covered by the resistive sheet.Field of SearchPrinting or reproduction deviceWindshield or window Including or comprising holding or support means for material to be heated Housing, casing, or support performs plural diverse functions (e.g., window) Comprising coating printed or deposited on core sheath or support means Heating element structure Combined with container, enclosure, or support for material to be heated With resistance heating means surrounding heating area Embedded within or between walls of container Muffle-type enclosure Oven type With plurality of separate heating units Crystal or other vibratory device With resistance heating element surrounding or embedded within walls of container | |
