    • Rechargeable generator consisting of an anode of an alkali metal or a malleable alkali alloy, at least one polymer electrolyte which is conductive with respect to alkali cations and acts as separator, as well as at least one cathode which is reversible to cations of alkali metal and its current collector. The anode comprises a thin metallic sheet, which includes at the surface thereof a passivation film SEI capable of limiting reaction between the metal and the polymer electrolyte and to exchange lithium ions. The polymer electrolyte comprises a homogeneous separator which is capable of transmitting a pressure on the anode to resist against the dendridic strain of the metal of the anode by undergoing a rate of deformation lower than 35% of its thickness. The polymer electrolyte of the separator, contains a maximum amount of species which are reactive towards lithium and which can accumulate at the surface of the anode to permit a preservation of the quality of the ionic exchanges at the interface of the anode and electrolyte and finally, the combination of anode, electrolyte, cathode and collector is maintained under a mechanical strain which is sufficient to ensure that the separator confines the anode sheet in place to preserve the integrity of the lithium-electrolyte interface during consecutive cycles of dissolution/plating.

    • The disclosure describes a method for the preparation of metallic alloys containing an alkali or alkali-earth metal, such as lithium, and a host metal, such as aluminum. Initially, an active organic solution of the alkali or the alkali-earth metal is prepared, and a source of the alkali or alkali-earth metal which are both brought together with one another. On the other hand, a metallic structure containing the host metal is prepared, the metallic structure is brought together with the organic solution which is kept in touch with the source of metal until there is formed an alloy of the host metal and of the alkali or alkali-earth metal with the metallic structure, and the alloy possesses an activity which is determined by that of the organic solution. The organic solution then acts as transfer agent of the alkali or alkali-earth metal towards the host metallic structure. To prepare a negative electrode, the alloy is brought together with an electrolyte, such as a thin polymeric film. The disclosure also describes the electrodes as well as the electrochemical generators produced by using these electrodes. Considerably improved properties of cycling are obtained.

    • The present invention relates to a kinetic wheel arrangement comprising a stator, a rotor and a magnetic suspension, wherein said rotor comprises a central recess about said axis of rotation; there is disposed in said central recess of the rotor a pressure system provided with a screw which is connected to the stator and of which the axis merges with said axis of rotation of the rotor, this pressure system being adapted to take a first position for which said rotor is free to rotate about its axis of rotation while being suspended by its magnetic suspension, and a second position for which it presses said rotor against said stator to immobilize it; and remotely-controlled means are provided to cut said screw between said stator and said rotor. The invention is particularly applicable to the caging of the rotor in phases during which the kinetic wheel arrangement undergoes considerable mechanical stresses.

    • The crankshaft bears a mark which passes in front of a sensor. When the crankshaft is rotated as the engine turns, the sensor delivers a squarewave signal when this mark passes in front of it. The mark and the sensor are positioned with respect to each other such that when the end of the mark passes in front of the sensor the piston is in a given low position and moves up toward the spark plug and such that when the other end of the mark passes in front of the sensor, the piston has substantially reached its maximum stroke within the cylinder in the vicinity of the spark plug, i.e. when it produces the maximum compression of the combustion gases located in the cylinder. The output of the sensor is connected to the input of a reset circuit of a counter and to the input of a count start and stop circuit of this counter and also to the input of a transfer control circuit. The count input of the counter is connected to the output of a pulse generator, such as a clock, for example, delivering pulses at a given constant frequency. The output of the counter is connected to the input of a buffer memory whose control input is connected to the output of the transfer control circuit. The output of the buffer memory is connected to the input of a permanent memory whose function will be explained further below. The output of the permanent memory is connected to a first input of a binary comparator whose other input is connected to the output of the counter. The output of the binary comparator is connected to the input of the ignition system, i.e. the spark plug. This connection, shown in a dotted line, can be achieved, for example, by an amplifier or any other electronic system making it possible, from an electric pulse delivered by a binary comparator, to produce between the electrodes of the spark plug a spark with a sufficient energy to produce the combustion of the combustion gases contained in the cylinder.
