[en] The paper breaks down into three sections. The first section covers the liability provisions under the Atomic Law as against those under the Paris and Brussels Conventions. The second section deals with the insurance aspect and the compulsory government indemnification scheme. In the third section the procedural problems arising from the use of the reservation on article 6 of the Paris Convention are treated and the advantages and disadvantages of an unconditional adoption of the Paris Convention are weighed. An overall survey of the legal consequences resulting from such adoption of the Paris Convention, with or without reservations, shows that the material results of the two alternatives are the same. The basic approach has been fixed already because, if use is made of the reservation, any liability of a third party causing of damage depends on full coverage. The debate about legal channelling thus is reduced to problems without any legal significance. One practical advantage of an unconditional adoption of the Paris Convention would be in the field of claims enforcement. The Convention streamlines the procedure by limiting third party liability to one person and by admitting claims for recourse only in cases of dolus directus. (HP/RF)

[en] The smallest size refrigeration plant likely to be required for liquid nitrogen cooled electric power transmission lines is considered. Nitrogen, neon, hydrogen, and helium cycles are compared and it is shown that a neon cycle has considerable potential. An outline is given of a practical plant utilizing the nitrogen cycle and mainly rotating machinery, all based on present-day technology. The advantages which evaporative cooling confers on the operation of LN₂ cryocables are explained

[en] The course of thermal dissociation of the following acetates of the rare earth elements: La(CH₃COO)₃.1 H₂O, Ce(CH₃COO)₃.CH₃COOH.1,5 H₂O, Pr(CH₃COO)₃.1.5 H₂O, Nd(CH₃COO)₃.1 H₂O and Sm(CH₃COO)₃.1 H₂O was examined, using the derivatograph OD 102, system F. Paulik-J. Paulik-L. Erdey. During thermal dissociation the hydrates of light lanthanon acetates turned into anhydrous acetates, metaacetates, basic carbonates and, in the end, into oxides of the particular rare earth elements. The thermal stability and ranges of temperatures of existence (under the examined conditions) of intermediate decomposition products of acetates of the particular light lanthanons were presented. The results obtained were compared with those of other authors. (author)

[en] Light lanthanons were separated by means of 1.5% NH₄-NTA solution of pH 2.6 to 4.8. Developing column was used in the form of Co²⁺. The concentration of lanthanons was high in the fractions; however, the good separation was not obtained. The pairs Nd-Pr and Pr-La were well separated when 1.5% Co-NTA solution of pH 4.0 to 4.9 was used as an eluent and developing columns were in the form of NH₄⁺. (author)

[en] In the concentration triangle tungsten - manganese - oxygen electro-chemical partial pressure-measurements were made. The oxygen partial pressure was determinded via electromotive power generated by a oxygen-ion-conducting solid cell. Special attention was paid to the measurements in the intersection MnO-WO₃. The line of the oxygen partial pressure curve against the composition made it possible to demarcate the concentration area of homogene, non-stoichiometric mixture phase which exists in this intersection. This area reaches at 1,000 degrees C from 40 mole per cent WO₃ to 50 mole per cent WO₃. At 700 degrees C it appears to shrink to 40 mole per cent. (orig./LN)
