Patent ID: 8884200

Claim:
An electromagnetically shielded inductor assembly comprising: an openable box-like induction coil forming at least one single turn coil when in a closed position to form an induction furnace in an interior furnace volume of the induction furnace with an entry perimeter and an exit perimeter, the openable box-like induction coil having a pair of pivot connections to allow a pivot opening of at least two opposing moveable sides of the openable box-like induction coil, an opposing longitudinal ends of the at least two opposing moveable sides of the openable box-like induction coil respectively forming the entry perimeter and the exit perimeter, the openable box-like induction coil having at least one pair of electric power terminal connections; a box-like electromagnetically shielded enclosure surrounding the openable box-like induction coil, the box-like electromagnetically shielded enclosure having a separate movable side section facing each of the at least two opposing moveable sides of the openable box-like induction coil to allow the pivot opening of the at least two opposing moveable sides of the openable box-like induction coil at least partially through an installed plane of each of the separate moveable side sections of the box-like electromagnetically shielded enclosure when the separate moveable side sections of the box-like electromagnetically shielded enclosure are at least partially removed from the installed planes of the separate moveable side sections; a workpiece entry passage and a workpiece exit passage within the box-like electromagnetically shielded enclosure, the workpiece entry passage and the workpiece exit passage respectively disposed at the opposing longitudinal ends of the openable box-like induction coil, the workpiece entry passage, the workpiece exit passage and the interior furnace volume of the induction furnace forming a path for a workpiece through the box-like electromagnetically shielded enclosure; and at least one gap in a region respectively between the entry and exit perimeters of the at least two opposing moveable sides of the openable box-like induction coil and an inner perimeter of the workpiece entry passage and the workpiece exit passage.
