| 20110316454 | ALTERNATING-CURRENT ELECTRIC MOTOR OF A COMBINED ELECTRIC DEVICE FOR POWERING AND CHARGING - The present invention relates to an alternating-current electric motor of a combined electric device for powering and charging, the said electric motor being formed by a stator connected to an electricity network of which the number of phases is lower than the number of phases of the said motor, the said charging current of the said network being injected via a connection point dividing each phase of the said stator connected to a phase of the said network into two half-windings, the said motor being characterized in that each half-winding of a phase comprises a plurality of coils wired together so as to reduce the magnetic linkage of each half-winding at the said connection point so that there exists an apparent non-zero inductance at the said connection point in charging mode of the said device. | 12-29-2011 |
| 20110316462 | ELECTRIC DEVICE FOR DRIVING MECHANICAL EQUIPMENT AND ASSOCIATED METHOD - The present invention relates to an electric device for driving mechanical equipment comprising an alternating current motor and an inverter, the said inverter comprising, for each phase of the said motor, an H bridge structure comprising four switching elements distributed over two branches connecting two terminals of the said H bridge structure and intended to supply the winding of the said at least one phase of the motor, the said winding being a winding with a mid point and the said electric device being characterized in that it also comprises, for each phase of the said motor, an energy storage unit, in particular a supercondenser, connected, on the one hand, to the mid point of the winding of the concerned phase of the motor and, on the other hand, to a terminal of the H bridge structure supplying the said winding. | 12-29-2011 |
| 20110316464 | ELECTRIC DEVICE COMPRISING AN ALTERNATING CURRENT ELECTRIC MOTOR AND A CONTROL INVERTER AND A METHOD FOR MEASURING THE ELECTROMOTIVE FORCE OF THIS DEVICE - The invention relates to an electric device ( | 12-29-2011 |
| 20110316465 | CONTROLLING METHOD OF SWITCHES OF SWITCHING ARMS, NOTABLY FOR CHARGING ACCUMULATION MEANS, AND CORRESPONDING CHARGING DEVICE - The present invention relates to a method for charging accumulation means via an external electrical network via at least a first (A) and a second (B) switching arm respectively comprising two switches ( | 12-29-2011 |
| 20110316481 | METHOD FOR CONTROLLING SWITCHES OF SWITCHING ARMS, IN PARTICULAR IN VIEW OF CHARGING ACCUMULATION MEANS, AND CORRESPONDING CHARGING DEVICE - A method for charging accumulation means configured by an electric charging device is disclosed. The charging device includes switching arms respectively including a first switch and a second switch. The method involves ordering a predetermined number of first switches to close respectively for an associated closure time, and on each opening of a first switch that was previously closed, another first switch is ordered to close for an associated closure time, so that a constant number of first switches are closed at a same time. | 12-29-2011 |

| 20110171104 | METHOD FOR OBTAINING ADN CRYSTALS THROUGH CRYSTALLIZATION IN A VISCOUS MEDIUM - The present invention relates to a method for crystallizing ammonium dinitramide (ADN), through spontaneous nucleation and crystal growth, from a solution containing said ammonium dinitramide (AND) dissolved in a solvent. Said solvent characteristically has a viscosity greater than or equal to 0.25 Pa s (250 cP) when said spontaneous nucleation is implemented. The ADN crystals obtained by said method have a median shape factor of 1 to 1.5 and are perfectly suitable for placement in the composition of energy materials. | 07-14-2011 |

| 20080207369 | BICYCLE CRANKSET WITH TWO CHAINRINGS - The bicycle crankset includes a bottom bracket axle, two cranks and a chainring carrier bearing first and second different toothed chainrings. The chainring carrier has the shape of a star, of which each arm is provided with a mounting hole aligned with a mounting hole in the first and second chainrings respectively. These holes accommodate elements for fastening chainrings to the chainring carrier, and they are arranged on a first circle with a predetermined diameter. Each arm of the chainring carrier is provided with a second mounting hole arranged on a second circle with a diameter that has been reduced relative to the first circle to match the chainring carrier to two other toothed circular chainrings with a size that is respectively reduced relative to the first and second chainrings and of which the mounting holes are located on the second circle. | 08-28-2008 |
