Abstract: An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle.

Abstract: The invention is a plasma-generating device useful in a wide variety of industrial processes. The plasma is formed in a chamber having a toroidal topology, and is heated inductively. As with all inductive plasmas, a primary coil carries an applied AC current, which, in turn, generates a corresponding applied AC magnetic flux inside the plasma. This flux induces current to flow through the plasma in closed paths that encircle the flux, thereby heating and maintaining the plasma. In this invention, the applied AC current flows through the primary coil around substantially the short poloidal direction on the torus. Accordingly, the applied magnetic flux is caused to circulate through the plasma along the larger toroidal direction. Finally, the current induced within the plasma will flow in the poloidal direction, anti-parallel to the applied primary current.
