Patent FR-2546000-A1 (FR)
Title: Vehicle battery charging and indicating circuit
Inventor: PAPAZIAN SAMUEL
IPC: H02J7/16
Filed: 1983-05-11
Abstract: The vehicle battery charging system, using a three phase generator for lighting and other equipment, includes an electronic control and warning circuit which indicates the charging state. A control unit contains a voltage divider which receives the voltage of the generator, connected by a Zener diode to a switching transistor. This is connected to a Darlington transistor for supplying the excitation winding of the generator. A voltage from one phase of the generator supply or from an auxiliary rectifier bridge is measured by a resistive bridge or by a voltage divider. When this falls and reaches a lower threshold value, a comparator operates a transistor connected to a point between the Zener diode and the switching transistor. In the case of a load disconnection, the Darlington transistor is operated, and combined with the operation of a logic circuit, the indicator lamp is protected from burning out.

Title: Improved catalyst for the metathesis of olefins
Inventor: BASSET JEAN MARIE MAURICE
IPC: B01J31/14
Filed: 1983-06-15
Abstract: Improved catalyst for the metathesis of olefins, which comprises a combination of W with a halogen and with a phenoxy group which may carry substituents. It contains 4 halogen atoms and 2 phenoxy groups per W atom. The phenoxy is preferably halogenated. This catalyst makes it possible to carry out more rapidly different types of metathesis reactions when it is employed as cocatalyst together with organometallic compounds, especially those of Al or of Sn.

Title: Process for the treatment of acid nitric aqueous effluents containing oxalic acid, usable in particular for treating the mother liquors from the precipitation of plutonium oxalate
Inventor: GERMAIN MICHEL
IPC: C02F1/02
Filed: 1983-11-04
Abstract: Process for the treatment of acidic nitric aqueous effluents containing oxalic acid, usable in particular for permitting the recycling of the mother liquors from the precipitation of plutonium oxalate. This process consists:     a. in adding a soluble vanadium compound to the said effluent;   b. in heating the said effluent.   After heating, by virtue of the presence of vanadium which promotes the decomposition of oxalic acid by nitric acid, the oxalic acid content of the effluent is sufficiently low to permit the recovery of plutonium by recycling in a plutonium purification plant.
