    Abstract: The invention relates to a magneto-optical data disc having at least one optically transparent, dimensionally stable substrate and at least one double-layer system comprising two exchange-coupled magnetic layers composed of alloys of rare earths with transition metals and having a vertical magnetic anisotropy. The first magnetic layer, adjacent to the substrate, has a composition corresponding to the formula I RExTM100-x-y-aPtyAa, I and the second magnetic layer on the side of the first magnetic layer remote from the substrate has a composition corresponding to the formula II REuTM100-u-bBb II where RE is at least one element from the series comprising Gd, Tb, Dy, Ho, TM is at least one element from the series comprising Fe, Co, A and B are, independently of each other, at least one element from the series comprising Cr, Nb, Ta, Al, Si, Ni, Mo, and 5

    Abstract: THE INVENTION RELATES TO A METHOD OF CONTROLLING A HYDRO.-ENATION OF A STARTING MATERIAL IN A HYDROGENATION REACTOR, IN WHICH THE AMOUNT OF HYDROGEN REACTED IN THE BYDROGENATION IS FIRSTLY DETERMINED, THE RATIO OF THE AMOUNT OF HYDROGEN REACTED TO THE AMOUNT OF STARTING MATERIAL FED IN IS THEN DERIVED, THIS RATIO IS COMPARED WITH A PRESCRIBED VALUE AND, FINALLY, AT LEAST ONE PROCESS PARAMETER IS ALTERED IF THE RATIO OF THE AMOUNT OF HYDROGEN REACTED TO THE AMOUNT OF STARTING MATERIAL FED IN DEVIATES BY A PRESCRIBED AMOUNT FROM THE PRESCRIBED VALUE.

    Abstract: ISOTHERMAL PROCESS FOR THE DEHYDROGENATION OF ALKANES Abstract Isothermal process for the dehydrogenation of alkanes to the corresponding alkenes over a catalyst bed comprising a dehydrogenation-active catalyst, wherein the catalyst bed comprises a catalytically inactive, inert diluent material. The catalytically inactive, inert diluent material is preferably selected from the group consisting of the oxides of the elements of main groups II, ill and IV, transition groups ill and IV and V, mixtures thereof and nitrides and carbides of elements of main groups ill and IV and preferably has a BET surface area of
