Laminated heating sheet
First Claim
1. IN AN ELECTRICAL HEATER COMPRISING OPPOSING ELECTRODES SEPARATED BY A SEMI-INSULATING ADHESIVE LAYER IN WHICH THE HEAT OUTPUT OF THE HEATER IS GENERATED BY THE PASSAGE OF ELECTRICAL CURRENT THERETHROUGH, THE IMPROVED STRUCTURE COMPRISING (1) A FIRST METAL FOIL SHEET ELECTRODE HAVING A POWER CONNECTION THEREON AND HAVING A RESISTIVITY R5 OHMINCHES, A THICKNESS T IN THE RANGE 0.0001-0.01 INCH, AND A LENGTH L INCHES FROM THE POWER CONNECTION TO THE FURTHERMOST END THEREOF, (2) A SECOND SHEET ELECTRODE HAVING A POWER CONNECTION THEREON AND BEING PARALLEL TO SAID FIRST ELECTRODE AND AT LEAST THE SAME THICKNESS THEREOF AND ADAPTED TO ESTABLISH A FLOW OF ELECTRICAL CURRENT FROM ONE ELECTRODE TO ANOTHER IN A DIRECTION PERPENDICULAR TO THE PLANES OF THE SHEET ELECTRODES WHEN A SUITABLE VOLTAGE IS ESTABLISHED ACROSS THE ELECTRODES, (3) A SEMI-INSULATING ADHESIVE LAYER OF THICKNESS D INCH AND RESISTIVITY RA OHM-INCHES IN THE RANGE 4X10**3 TO TO 4X10**7 SANDWICHED BETWEEN OPPOSING FACES OF SAID FIRST AND SECOND SHEET ELECTRODE AND BONDED TO THE OPPOSING FACES OF SAID ELECTRODES OVER SUBSTANTIALLY THE ENTIRE AREA THEREOF AND IN ELECTRICAL CONTACT THEREWITH, AND (4) SAID THICKNESS T INCH OF SAID FIRST ELECTRODE BEING ESTABLISHED BY THE RELATIONSHIP
