    摘要: The present invention relates to an electrochemical cell comprising a solid electrolyte conductive for O.sup.2- anions in contact with an anode and a cathode of identical or different composition, the electrolyte solid being comprised of a composition derived from Bi.sub.4 V.sub.2 O.sub.11 of which at least one of the cationic constituent elements is substituted by at least one substituting element chosen such that the gamma phase structural type of Bi.sub.4 V.sub.2 O.sub.11 is maintained, as well as the equilibrium of charges, at least one of the anode or the cathode including two parts, a first part being of a mixed electronic and ionic conductive material in contact with the solid electrolyte, the second part being an electronic conductive material superposed on the first part. The invention equally relates to the use of the electrochemical cell with a view towards the separation or the extraction of oxygen.

    摘要: A stack of parts, such as the stator disks of a turbomolecular pump, the parts being stacked alternately with spacers, includes a spacer having a knife-shaped deformable portion. When the stack is installed for the first time, the portion is compressed so as to take up the tolerances of the stack between abutment surfaces, e.g. delimited by a pump body and a corresponding casing. The invention applies in particular to turbomolecular pumps and aims to eliminate the operations of adjustment, re-machining, or matching that are usually required when installing a stator assembly.
