  • Patent number: 4871650
    Abstract: For coating printing cylinders or sleeves with a seamless, smooth photosensitive layer, two or more strata of a thin, prefabricated, essentially solvent-free, unsupported, thermoplastically processible, solid, photosensitive layer are applied to the printing cylinder or the sleeve, without bubbles and with displacement of the air between the individual strata, and the total photosensitive layer material is then heated under pressure and with joining or fusion of the individual strata to form a single, continuous photosensitive layer, and the surface of the resulting photosensitive layer is aftertreated to shape it exactly to size and is smoothed, with formation of an exactly cylindrical shape.

  • Patent number: 4871701
    Abstract: Pentasil coated catalysts and fully crystalline catalysts in which the individual pentasil crystals are larger than 5 .mu.m are prepared by hydrothermal treatment of SiO.sub.2 by a process in which the SiO.sub.2 moldings are subjected to a hydrothermal treatment at from 140.degree. to 220.degree. C. in an alkali-free mixture of water, an amine and/or a tetraalkylammonium compound, with or without ammonia. The aluminum component for the preparation of an aluminosilicate zeolite can be kneaded into the SiO.sub.2 moldings or fed in via the liquid phase during the hydrothermal treatment.
