    Abstract: Irreversible optical recording medium is based on a substrate with texturised surface and a metal or semiconductor film with an optical absorption of 5-95% and thickness of 10-50 nm. The novelty is that the texture consists of hemispherical structures, which change when exposed to light. The hemispherical structures are pref. arranged statistically and consist of raised or dented areas with a uniform dia. of over 200 nm and up to 500 nm or of different dia. values within this range.

    Abstract: For the purpose of quasi-isothermal catalytic conversion of SO2 into SO3, a plurality of rows of cooling-tube bundles (bunches) (6) disposed behind one another are arranged in such a way in the catalyst bed (2) of a contact vessel (1), that the bundles of successive rows are arranged so as to be offset with respect to those of preceding rows. The spacing of the cooling tubes in the bundles (6) is selected in such a way that virtually no entire catalyst bodies penetrate into the bundles. The bundles are designed in such a way that the pressure drop (pressure head loss) of the gas in the bundles (6) corresponds approximately to the pressure drop in the catalyst layer (2) between the bundles. The spacing (5, 5a-5c) of the bundles is no greater than the width of the bundles (6).

    Abstract: The invention relates to a process for producing magnetic recording media for perpendicular recording by coating, by means of a PVD process, a non-magnetic substrate with a cobalt-containing, ferromagnetic metal layer which has a magnetic anisotropy perpendicular to the plane of the coating, the temperature of the substrate being increased during the coating by means of external heating.

    Abstract: Light-sensitive registering material for registering information by local alteration of the optical properties of a registering layer using light radiation with high energy density, consists of a substrate (I), a particulate layer (II) of almost spherical particles and a superimposed metal film (III). (II) consists of an organic polymer softening at temps. above 50 deg.C and has an average particle dia. not more than 5000 nm. (II) consists of a polymer with softening point at 50-150 deg.C and average particle dia. 303-5000 nm. The material is prepd. by coating (I) with a polymer dispersion, hardening this and then applying (III). The material is exposed with light of wavelength 200 nm to 2 microns and an incident radiation energy of at least 0.1 J/cm2.
