20080297159 | Sensing Apparatus for Detecting an Interface Between First and Second Strata of Materials - A sensing apparatus for detecting an interface between first and second materials, each have a different dielectric loss factor, disposed in a stratified manner in a volume of materials having a predetermined depth comprises a length of transmission line having an inner conductor surrounded by a dielectric material and a shielding conductor. The transmission line may be coaxial or planar in form. | 12-04-2008 |
20090095745 | Microwave Field Director Structure Having Vanes With Inner Ends Wrapped With A Conductive Wrapper - A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, with each vane extending radially outwardly from a central axis. Each vane is angularly adjacent to two other vanes and is attached to each other at their inner ends. Each vane has a predetermined thickness dimension. | 04-16-2009 |
20090095746 | Microwave Field Director Structure Having Vanes Covered With A Conductive Sheath - A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, with each vane extending radially outwardly from a central axis. | 04-16-2009 |
20090095747 | Microwave Field Director Structure Having Vanes With Outer Ends Wrapped With A Conductive Wrapper - A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, with each vane extending radially outwardly from a central axis. Each vane is angularly adjacent to two other vanes and is attached to each other at their inner ends. Each vane has a predetermined thickness dimension. | 04-16-2009 |
20090095749 | Microwave Field Director Structure Having Metal Vanes - A self-supporting field director structure for use in heating an article in a microwave oven includes a plurality of vanes connected to a central support member. Each vane is formed from an electrically conductive metallic material. Each vane extends radially outwardly from a central axis, with the radially inner end of each vane being spaced a predetermined separation distance from the axis. | 04-16-2009 |
20120312810 | SUSCEPTOR ASSEMBLY AND FIELD DIRECTOR ASSEMBLY FOR USE IN A MICROWAVE OVEN - A susceptor assembly comprises a generally planar susceptor having an electric field director structure mechanically connected thereto. The field director structure includes at least one, but more preferably, a plurality of two or more vanes mechanically connected to the susceptor. Each vane has a surface at least a portion of which is electrically conductive. The vane(s) are most preferably disposed substantially orthogonal to the planar susceptor. The connection may be either a fixed or a flexible articulating connection. | 12-13-2012 |
20130068760 | MICROWAVE FIELD DIRECTOR STRUCTURE HAVING VANES COVERED WITH A CONDUCTIVE SHEATH - A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, with each vane extending radially outwardly from a central axis. Each vane is angularly adjacent to two other vanes and is attached to each other at their inner ends. Each vane has a predetermined thickness dimension. | 03-21-2013 |
20130126520 | MICROWAVE FIELD DIRECTOR STRUCTURE HAVING VANES WITH OUTER ENDS WRAPPED WITH A CONDUCTIVE WRAPPER - A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, each vane extending radially outwardly from a central axis and being angularly adjacent to two other vanes. The vanes are attached to each other at their inner ends. Each vane has a substrate formed from an electrically non-conductive material and an electrically conductive wrapper that wraps the substrate so that a portion of the first and second major surfaces are covered and the radially outer end of each vane is wrapped by an electrically conductive material. The wrapper and the substrate are arranged in a laterally symmetric fashion so that thermal expansion effects due to heating are equalized across the thickness of each vane. | 05-23-2013 |
20130139714 | METHOD FOR MAKING FLEXOGRAPHIC PRINTING FORMS BY WELDING EDGES OF PHOTOSENSITIVE ELEMENTS WITH MICROWAVE ENERGY - This invention pertains to a process for making flexographic printing forms, particularly relief printing forms, from two or more photosensitive elements welded to one another at their edges, wherein the welding is accomplished by microwave energy. This invention also relates to sealing edges of a cylindrically-shaped photosensitive element. Using microwave energy provides a smooth surface upon welding with a near disappearance of the weld-lines. | 06-06-2013 |
