    • This invention provides a system for providing heat to a substrate in an alternating magnetic field using lossy heating particles. This invention in particular discloses an article which is a combination of a base material and lossy heating particles capable of producing the desired heat and capable of being self-regulating at a preselected Curie temperature when subjected to an alternating magnetic field. The article of this invention is adapted to be placed on a substrate in order to heat the substrate in an alternating magnetic field and is adapted to provide the removal of the particles from the substrate after the heating is completed. Preferred materials for the article of this invention are gel materials having a cone penetration of at least about 50(10.sup.-1 mm) and at least about 100% elongation. Preferred magnetic particles for use in this invention include the combination of lossy heating particles, alone or in combination with nonlossy particles for maintaining the magnetic circuit coupling while the lossy heating particles are at the Curie temperature.
    • 本发明提供了一种使用有损加热颗粒在交变磁场中向衬底提供热量的系统。 本发明特别公开了一种制品,其是当经受交变磁场时,能够产生所需热量并且能够以预选的居里温度自调节的基材和有损加热颗粒的组合。 本发明的制品适于放置在基板上,以便在交变磁场中加热基板,并且适于在加热完成之后提供从基板上去除颗粒。 用于本发明制品的优选材料是具有至少约50(10-1mm)的锥形穿透和至少约100%伸长率的凝胶材料。 用于本发明的优选磁性颗粒包括单独的或与非磁性颗粒组合的有损加热颗粒的组合,用于在有损热的加热颗粒处于居里温度时保持磁路耦合。
