Abstract: An apparatus and method for molding thermosetting material into shaped articles rapidly and without the occurrence of hot spots or other defects. A mold having a cavity conforming to the shape of the article to be molded is provided and is filled with thermosetting material. An energy source generates electromagnetic energy in the microwave range and a coupling means is provided for causing the electric field component of the generated energy to uniformly irradiate the volume of thermosetting material in the mold cavity.

Abstract: An apparatus for efficiently coupling microwave energy to a highly dissipative load such as a plasma lamp tube. A longitudinally extending lamp tube is enclosed in a longitudinally extending non-resonant microwave chamber having a pair of coupling slots therein which are oriented perpendicular to the direction of the lamp tube. The slots are azimuthally offset in opposite directions with respect to a longitudinally extending top center line of the chamber by about 15.degree. to 20.degree., and are located near respective ends of the chambers but at different distances therefrom. Microwave energy from a pair of microwave energy generating means is coupled to the respective slots with the frequency outputs of the generating means being offset from each other by a small amount.

Abstract: In an apparatus for curing photosensitive inks and coatings comprising an ultraviolet light emitting lamp unit comprised of a tubular elongated ultraviolet lamp and a reflector, and means for moving a substrate, on which said inks or coatings are deposited, under said lamp unit the improvement wherein said reflector is comprised of a first reflecting means for providing a region of peaked relatively high intensity illumination on said substrate and a second reflecting means for providing a region of relatively lower illumination upstream of said high intensity illumination for pre-curing the ink or coating on said substrate.
