Portable induction heater
First Claim
1. An induction heater assembly for heating a metallic substance hidden beneath a sheet of material, said induction heater assembly comprising:
- an induction coil for remotely heating said metallic substance through said sheet of material;
a sensor device for detecting a hidden location of said metallic substance beneath said sheet of material;
a visual indicator device; and
a control device coupled to said sensor device and said visual indicator device for receiving an output from said sensor device and controlling said visual indicator device responsive to said sensor device output to indicate a direction in which the induction heater assembly must be moved to facilitate placement of said induction coil over said metallic substance.

Abstract
An induction heater having an induction coil (26) for heating a metallic substance (4) hidden by a membrane (2), the metallic substance being coated with a heat activated adhesive on its side adjacent the membrane (2). The heater having four location sensor coils (36) for detecting the position of the hidden metallic substance and means to facilitate the placement of the induction coil (26) over the hidden metallic substance (4), based on information from the sensors. Once the induction coil (26) is over the metallic substance (4) it is used to heat the adhesive thereby adhering the metallic substance (4) to the membrane (2). The sensors (36) are adjacent the inductor coil (26) and are insulated therefrom by an air gap (38).
