20080217325 | Apparatus and method for inductive heating of a material in a channel - Apparatus and method for inductive heating of a material located in a channel. In one embodiment, the heating assembly comprises an interior coil, an exterior sheath inductively coupled to the coil, a dielectric material disposed between the coil and sheath, and a conductor for supplying a signal to the coil to generate the magnetic flux for inductive heating of the sheath. The heating assembly is disposed in the material in the channel, and the magnetic flux generated by the coil may also inductively couple to the material in the channel. The material may be heated from a nonflowable to a flowable state, such as heating a metal or polymer plug formed in a melt channel of a molding apparatus. | 09-11-2008 |
20090001066 | Spray Deposited Heater Element - The present disclosure relates to a heater that may be applied to a substrate. The heater may include a graduating material deposited on at least a portion of a substrate, a resistive material and a thermal barrier dielectric coating. The resistive material may include at least two resistive compositions, wherein the resistivity of the material may be altered by varying the composition in given areas. | 01-01-2009 |
20090084775 | INDUCTIVE HEATING APPARATUS AND METHOD - Apparatus and method for inductive heating wherein an internal inductive heating assembly is provided within a bore of a solid article. The heating assembly includes an interior coil inductively coupled to a portion of the article adjacent the bore to inductively heat the article. The heating assembly lacks an internal cooling mechanism and the coil thermally coupled to the adjacent article portion for transmission of heat from the coil to the article. A signal is provided to the coil to generate a magnetic flux for inductive heating of the adjacent article portion | 04-02-2009 |
20100025391 | COMPOSITE INDUCTIVE HEATING ASSEMBLY AND METHOD OF HEATING AND MANUFACTURE - A composite inductive heating assembly capable of providing in various embodiments, one or more of a variable or higher power density, tighter temperature control, reduced power consumption, longer operating life, and lower manufacturing costs, particularly in a compact design. A composite inductive heating assembly includes an inner layer of dielectric material, a multi-turn coil disposed over the inner layer, and an outer self-supporting body of moldable flux concentrator material rendering the inner layer, coil and flux concentrator into a self-supporting assembly. Select embodiments of the composite heating assembly include a nozzle heater and a manifold heater. A method of manufacturing the composite heater in a mold, with application of heat and pressure, is described. | 02-04-2010 |
