| 20100301038 | Induction Heat Treatment of Workpieces - An apparatus and process are provided for induction heating of a workpiece. The workpiece is moved through an inductor to inductively heat treat the workpiece with electric power of varying frequency and duty cycle or amplitude control to control the magnitude of electric power as the frequency changes. Alternatively the workpiece may be stationary and the inductor can be moved along the workpiece, or combined and coordinated movement of both the workpiece and inductor can be used. | 12-02-2010 |
| 20090314768 | Gradient Induction Heating of a Workpiece - An apparatus and process are provided for gradient induction heating or melting of a workpiece with a plurality of induction coils, each of the plurality of induction coils is connected to a power supply that may have a tuning capacitor connected across the input of an inverter. The plurality of induction coils are sequentially disposed around the workpiece. The inverter has a pulse width modulated ac power output that may be in synchronous control with the pulse width modulated ac power outputs of the other power supplies via a control line between the controllers of all power supplies. | 12-24-2009 |
| 20090291320 | Bonding of Materials with Induction Heating - An apparatus and process are provided for forming a two-metal flat bonded article. A flat metal sheet in solid form is placed in the indention of a heat resistant plate. A second heat resistant plate is placed over the flat metal sheet in the indentation to form a flat metal sheet enclosure. The flat metal sheet enclosure is placed in a U-shaped inductor assembly embedded with a solenoidal induction coil. Supply of alternating current to the solenoidal induction coil inductively heats the flat metal sheet after which the sheet is withdrawn from the inductor assembly. The second heat resistant plate is removed and a bond metal in liquid form is placed over the top surface of the flat metal sheet in the indentation so that the two-metal flat bonded article is formed as the bond metal solidifies. | 11-26-2009 |
| 20090230121 | Electric Induction Impeder - An impeder for use in an electric induction welding process is provided. Optionally the impeder does not require internal forced cooling. In embodiments using internal forced cooling a high efficiency cooling system is provided. | 09-17-2009 |
