Abstract: Optical recording medium is based on a polymeric support (I) coated with a highly reflective metal film (II). The novel features are that (I) is a uniaxially oriented plastics film and (II) has uniform crystallographic orientation of the crystallites corresp. to the orientation of (I). Pref. (I) consists of a polymeric base and a uniaxially oriented polymeric coating. (II) consists of Sn, Te or Bi deposited from the vapour phase. Suitable substrates consist of polyethylene, polypropylene, polybut-1-ene or isotactic polystyrene, opt. on a polymethyl methacrylate (PMMA) base.

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: Optical recording media for recording and retrieval of information by means of high energy radiation, which media consist essentially of a polymeric base having uniaxial orientation and, applied on this, a metal film of high reflectivity having the orientation of the crystallites corresponding to the orientation of the base and retrieval of information are effected by means of high energy radiation.
