Process for the recovery of Co or Ni, comprising the steps of:preparing a metallurgical charge comprising Fe, slag formers, and a useful load containing either one or both of Co and Ni;feeding the charge to a shaft furnace; andsmelting the charge so as to form a Co or Ni-bearing alloy, an Fe-bearing slag and a gaseous phase,characterised in that the useful load comprises at least 30 wt. The signal is decrypted in the second device using a decryption key generated from a preceding part of the received and decrypted signal. For operating conditions with a high recognition rate with a plurality of transponders located within a detection field, the basic transmission frequency fs1 is reduced to a fixed alternative value fs2. An opposite wall of the diffuser is defined either by the engine cylinder head or a portion of the center housing, depending on whether the CHRA slides into the receptacle compressor-wheel-first or turbine-wheel-first. A vehicle includes a traction motor, a transmission that is selectively connected to the traction motor, fluid-cooled devices each in electrical communication with the motor, and a controller configured to execute the arbitration method noted above. In the deployed position the shelf can support crockery items.
