摘要： A STABILIZED HIGH FREQUENCY POWER OSCILLATOR FOR HEAT SEALING THERMOPLASTIC MATERIAL IS PROVIDED WITH A TANK CIRCUIT CONSTRUCTED OF THREE CONCENTRIC CONDUCTING TUBES. A CONDUCTING LOWER LEDGE CONNECTS THE INNER AND OUTER TUBES AT THEIR LOWER ENDS, WHILE AN UPPER CONDUCTING LEDGE CONNECTS THE INNER AND INTERMEDIATE TUBES AT THEIR UPPER ENDS. AN ADDITIONAL LEDGE EXTENDS INWARD FROM THE OUTER TUBE, PARTIALLY OVERLIES THE UPPER LEDGE, AND IS CLOSELY SPACED WITH RESPECT THERETO. FINE TUNING IS ACHIEVED BY CONTROLLING THE SPACING BETWEEN THE UPPER LEDGE AND THE ADDITIONAL LEDGE. THE POWER OSCILLATOR TUBE IS SECURED TO THE UPPER LEDGE AND EXTENDS INTO THE INNER TUBE. THE FEEDBACK LOOP IN THE CONTROL GRID CIRCUIT EXTENDS THROUGH ALIGNED APERTURES IN THE UPPER AND ADDITIONAL LEDGES INTO THE SPACE BETWEEN THE TWO INNERMOST TUBES. THE HIGH VOLTAGE LEAD FEEDING THE PLATE OF THE OSCILLATOR TUBE EXTENDS THROUGH OTHER ALIGNED APERTURES IN THE UPPER AND ADDITIONAL LEDGES, THROUGH THE SPACE BETWEEN THE TWO INNERMOST TUBES, BELOW THE MIDDLE TUBE AND OUTSIDE OF THE TANK, THROUGH AN OPENING AT THE BOTTOM OF THE OUTER TUBE. A PLURALITY OF INSULATORS PROJECTING OUTWARD FROM INWARD DEPRESSIONS IN THE MIDDLE TUBE REST AGAINST THE INNER SURFACE OF THE OUTER TUBE TO MAINTAIN THE DESIRED SPACING BETWEEN THE OUTER AND MIDDLE TUBES.

摘要： A dielectric heat sealing apparatus includes a rotatable drum and drum buffer spaced from, and at least partially axially overlaying the circumference of said drum, the buffer being attached to the drum to rotate therewith. The buffer and drum surface are preferably made of slippery, insulating materials, such as polytetrafluoro-ethylene-impregnated fiberglass. A metallic electrode is interposed in the space between the drum buffer and the drum surface, and a movable metallic belt is pressed against the drum buffer over a predetermined portion thereof to press a workpiece which it to be sealed between the metallic belt and the drum buffer. Upon application of radio frequency voltage between the belt and metallic electrode, the work pieces are dielectrically heated to seal same.
