Abstract: An antenna concept for radiating intense, high power electromagnetic fields in the RF regime without electrical breakdown. The invention accomplishes this with high aperture and power efficiency, high gain, and in a geometry that is compact and conformal to a planar or curved surface. The antenna concept is compatible with standard rectangular waveguide feeds, or other hybrid transmission line geometries.

Abstract: The invention provides an improvement to the feed path for conventional round balers in the agricultural industry, and reduces the jamming of baling material in the feed gap of the baler. In a commonly known round baler the baling material enters the bale forming chamber through a feed gap defined by an upper roller rotating away from the bale forming chamber, and a lower roller rotating towards the bale forming chamber. As the upper roller is moving counter to the flow of baling material into the bale forming chamber, baling material which contacts it is retarded, and tends to form a ball of material which can plug the feed gap. The present invention provides a plate covering the upper roller which plate deflects the baling material into the feed gap and prevents the baling material from contacting the upper roller. The invention could be provided as an integral flange manufactured in new balers, or could be produced as a mountable plate for retrofitting of existing equipment.
