Abstract: A system controls a drivability mode of a hybrid motor vehicle provided with a heat engine and with an electric engine. The system includes a first measurer for measuring running conditions of the vehicle, a second measurer for measuring a level of charge of a battery of the vehicle, a first controller for controlling the heat engine, a second controller for controlling the electric engine, a computer capable of emitting a first activation signal for the heat engine, and a second activation signal for the electric engine, as a function of the running conditions and of the level of charge, and a third measurer for measuring at least one characteristic relating to an operation of a heating system of the vehicle. The first activation signal and the second activation signal are generated on the basis of the characteristic relating to the operation of the heating system.

Abstract: An electrochemical battery having high energy per unit mass, and in particularly a lithium and thionyl chloride battery, comprising a stack (10) of positive and negative electrodes within a housing (2) closed by a cover (3), two metal terminals connected respectively to said positive electrodes and said negative electrodes passing through the stack and emerging from said cover, the battery being characterized by the fact that one of said terminals (24) is in the form of a hermetically closed tube (30) lined internally with a capillary structure, filled with a heat-conveying fluid, and passing through the bottom (7) of said housing to be in contact with a cooling means (33), said terminal thus constituting a heat pipe for said battery.

Abstract: A method for selectively dissolving non-ferrous metals contained in pyritic ores by the steps of crushing the ores, introducing the crushed ore at a temperature above the ambient temperature into a reaction vessel containing a solution of chlorides of a metal having two valance states, and injecting gaseous chlorine into the reaction vessel at a rate such that the oxido-reduction potential of the solution of chlorides remains between 400 and 700 mv during the operation.
