    摘要： An apparatus and process are provided for bonding of materials by induction heating of an electrically conductive material upon which a second material is bonded. The electrically conductive material is induction heated between a first induction heating plate, and the combination of a frame and a second induction heating plate that is disposed within the frame. The second induction heating plate is removed from the surface of the electrically conductive sheet, while the frame continues to hold the electrically conductive sheet flat, and the second material, in liquid form, is poured into the interior opening of the frame in which the second induction heating plate was originally placed. The liquid material solidifies and bonds to the electrically conductive sheet to produce a bonded product. A continuous sheet of an electrically conductive material may be bonded to a continuous sheet of a second material by pressing them together and moving the pressed together materials through an induction coil to inductively heat the electrically conductive material and bond it with the second material.

    摘要： An apparatus and process are provided for controlling the heating and melting of a material that is non-electrically conductive in the solid state and is electrically conductive in the non-solid state. Power is selectively directed between coil sections surrounding different zones of the material in a susceptor vessel by changing the output frequency of the power supply to the coil sections. Coil sections comprise at least one active coil section, which is connected to the output of the power supply, and at least one passive coil section, which is not connected to the power supply, but is connected in parallel with a tuning capacitor so that the at least one passive coil section can be selectively operated at, or near, resonant frequency when the transition material in the vessel is molten. Depending upon the state of the transition material in the susceptor vessel, the frequency of the power applied to the active coil section can be changed to generate a magnetic field that selectively couples with the susceptor vessel, transition material in the vessel, and/or the passive coil section.

    摘要： An electromagnetic pump has a supply section and a magnetic force pumping section wherein flow of an electrically conductive material through the supply section is opposite to the flow of the material in the magnetic force pumping section in some examples. Multiple coils surround the supply and magnetic force pumping sections. Current flowing through the multiple coils creates magnetic fields that magnetically couple with a magnetic material disposed between the supply and magnetic force pumping sections so that the fields penetrate the electrically conductive material in the magnetic force pumping section substantially perpendicular to the desired flow direction which maximizes the magnitudes of magnetic forces applied to the electrically conductive material. Alternatively the electromagnetic pump has a supply section and a magnetic force pumping section wherein flow of an electrically conductive material through the supply section is in the same direction as the flow of the material in the magnetic force pumping section.

    摘要： In one embodiment, an induction furnace is disclosed having a crucible, first and second set of induction coils surrounding the crucible and master and slave inverters, whereas in another embodiment, related to a channel-type induction furnace, the lower portion of the crucible houses at least first and second induction coils. The master and slave inverters each have a switching device with known turn-off-time characteristics for generating an alternating polarity output voltage across a load. The master inverter monitors the current, detects the zero-crossing of the current in the first induction coils, and generates a control signal in response to such detection of zero-crossing. The control signal is generated at an interval following the detection of the zero-crossing which is greater than the turn-off-time characteristic of the switching device. The control signal is introduced into a selectable delay line before it is applied to the slave inverter so as to produce a relative phase difference between the output voltages of the master and slaver inverter.
