    • A heating element for retaining heat applied by reaction with high-frequency microwave radiation is provided in various forms. In one form, the heating element includes a multi-layered cartridge having a center core for dissipating heat, a layer of material reactive to microwave radiation for retaining heat and an outer layer of paper for substantially sealing the cartridge, yet permitting heat to radiate in use from the cartridge. In another form, the heating element has multiple layers formed of a rubber and cellular material for retaining water, the multiple layers being disposed about a central core of wax material. In a still further form, the heating element may comprise clay disposed within a covering, the clay containing minerals or aromatics, depending upon its use. In all such heating elements, the materials comprising the elements are reactive to high-frequency microwave radiation to retain heat and radiate such retained heat upon application for their intended purposes.This application is a continuation-in-part of application Ser. No. 918,729, filed Oct. 14, 1986, now U.S. Pat. No. 4,743,726 issued May 10, 1988.
    • 以各种形式提供用于保持通过与高频微波辐射反应而施加的热的加热元件。 在一种形式中,加热元件包括具有用于散热的中心芯的多层盒,可反应用于保留热的微波辐射的材料层和用于基本上密封盒的外层纸,同时允许热辐射 从墨盒使用。 在另一种形式中,加热元件具有由用于保持水的橡胶和多孔材料形成的多层,多层围绕蜡材料的中心芯设置。 在另一种形式中,取决于其用途,加热元件可以包括布置在覆盖物内的粘土,含有矿物质或芳族化合物的粘土。 在所有这样的加热元件中,包含这些元件的材料对高频微波辐射是有反应性的,以便在施加其预期目的时保持热量并辐射这种保留的热量。 该应用程序是应用程序Ser的部分继续。 1986年10月14日提交的美国专利第918,729号。 1988年5月10日授权的第4,743,726号。
