  • Patent number: 9736977
    Abstract: The subject matter of the present invention is a method for treating pourable products made of particles which can be separated, preferably seeds (2), with accelerated electrons. During the method, a transparent product flow is guided, using gravity, in a product guiding channel (1) through the electron field generated by at least one electron accelerator (12) under low pressure or excess pressure. The product flow is guided by means of an accelerated gas flow (5) in such a way that the movement thereof corresponds in magnitude and direction to the accelerated movement, which the falling particles execute in said gas flow due to gravitational acceleration. In addition, a device is disclosed which realizes the acceleration of the gas flow (5) in the required way through the shaping of the product guiding channel (1).

  • Patent number: 5955829
    Abstract: Electron gun with band-shaped beams that includes a vacuum chamber extend in a longitudinal direction, a beam window running in the longitudinal direction along the vacuum chamber, and a cathode control-electrode system positioned within the vacuum chamber in the longitudinal direction. The cathode control-electrode system includes at least one substantially straight cathode positioned substantially parallel to a longitudinal axis of the cathode control-electrode system and the at least one substantially straight cathode has bulges formed at defined distances. The bulges are shaped to produce a substantially homogeneous current density distribution along the at least one substantially straight cathode and support units are located in the cathode control-electrode system to correspond with the bulges. The bulges are removably couplable to the support units.
