Color dichroic polarizer includes a glass substrate, a surface layer, and non-spherical metal particles arranged in the surface layer and being deposited in an oriented arrangement. Wherein, in at least one lateral region of the glass substrate, the surface layer comprises a double layer whose two partial layers contain metal particles with different average axis ratios, whereby the two partial layers have different absorption spectra. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Color dichroic polarizers and method for the production thereof

Process and device for treating seeds in order to combat harmful organisms. According to the invention, in an initial stage of the process, the seeds are separated and distributed evenly in a free-fall process, subjected in a vacuum to irradiation by low energy electron beams and then immediately treated with fungicides and/or microbial antagonists or metabolic products and spores thereof and/or synergists.

Process and device for treating seeds

Multiple methods are known to process materials or alter their properties using an electron beam. Until now, it was not possible to impinge upon minuscule surface sections (pixel) with a given arrangement on the surface in order to achieve certain effects. According to the invention, the object to be impinged upon is moved contact-free under a mask. A bidimensional deflectable electron beam oscillating at a high frequency perpendicular to the direction of movement of the object is moved on the mask, the speed being essentially faster than that of the movement of the object. Said method can be used for processing any material, preferably plane or band-shaped objects, in order to achieve processing effects by means of physical or chemical reaction.

Method for structured energy transmission using electron beams

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.
