For the comminution of fresh wash powder coarse particles after drying, a hammer bar mill can be used, the beater wheel (3) of which is equipped with two diametrically opposite, enlarged clearing beaters (9) which keep a milling space (8) on the circumference (6) of the beater wheel (3) free and thus prevent a blocking of the beater wheel (3). The peripheral edge (10) of the clearing beater (9) ca...

An optical element made from crosslinked polymers is worked by ablative photochemical decomposition. To this end, the crosslinked polymer is exposed to controlled, coherent irradiation whose photon energy is significantly higher than the dissociation energy of the covalent bonds in the polymer and whose fluency is sufficient to remove the resultant decomposition products.
