Propulsion system (1) comprises a frame (2) provided with at least one wheel (3) driven by an electric machine, and at least one non-driven wheel (4), a handlebar (20) and means (5) for coupling the propulsion system to the rolling object, coupling means (5) comprising means for gripping and lifting at least one wheel of the rolling object. Handlebar (20) comprises a connection with frame (2) and/or driven wheel (3). Furthermore, the connection comprises a means (12) for locking/unlocking the handlebar relative to frame (2) and/or to a driven wheel (3) from a locking position where handlebar (20) is attached to frame (2) and/or to driven wheel (3), this locked position of handlebar (20) enabling electric propulsion system (1) to be moved by means of handlebar (20), to an unlocking position enabling at least free motion of handlebar (20) relative to frame (2) and/or driven wheel (3).

摘要: The present invention relates to a device (1) for measuring the oxidation stability and/or the thermal stability of any type of fuel, including diesel fuel, by miniaturization of the test system by use of a microfluidic technique. The physical phenomena to which fuels are subjected are reproduced by the microchannels (12) of the microfluidic chip (7), which comprise a representation of at least one of the fuel injection and the fuel circulation for a drive system, an internal-combustion engine or an aircraft reactor for example.

摘要: The invention relates to an integrated method for thermal conversion and indirect combustion of a heavy hydrocarbon feedstock in a redox chemical loop for producing hydrocarbon streams. The heavy hydrocarbon feedstock (1) is brought into contact with inert particles (2) in a thermal conversion zone (100). Thermal conversion in the absence of hydrogen, water vapour and a catalyst produces a first gaseous effluent of hydrocarbon compounds (4) and coke, which effluent is deposited on the inert particles (5). The latter is then burned in a redox chemical loop (200) in the presence of oxygen-carrying solid particles (6). The inert particles thus flow between the thermal conversion zone (100) and a reduction zone (300) of the chemical loop while the oxygen-carrying solid particles flow between the oxidation (400) and reduction zones (300) of the chemical loop.

摘要: The object of the invention is a method of controlling a permanent-magnet synchronous or synchro-reluctant three-phase rotary machine (4), comprising the following steps:
measuring a current (iA, iB, iC) flowing through each phase of a stator of rotary machine (4);
first calculating, by use of a single proportional-integral controller, a switching control signal for controlling an inverter (10), according to each measured current (iA, iB, iC), and of a target value (Tref) of a mechanical torque provided by the rotary machine (4) or of a target value of an angular speed of a rotor of rotary machine (4) in relation to the stator wherein the inverter (10) is configured to convey electrical energy between a continuous electrical energy source (8) and each phase of the stator of rotary machine (4); and controlling the inverter (10) by use of the calculated switching control signal.-

摘要: The invention relates to a method for recovery of hydrocarbons present in an underground formation by injection of a saline aqueous solution comprising at least one surfactant, by means of a numerical flow simulator including a model of the evolution of the interfacial tension between the saline aqueous solution and the hydrocarbons as a function at least of salinity, wherein the interfacial tension evolution model is calibrated as follows: i) carrying out interfacial tension measurements for a plurality of emulsions having distinct salinity values corresponding at least to the optimum salinity, to two salinities bounding the optimum salinity in a 5-10% limit, to the zero salinity and to the solubility limit of the salts; ii) determining the constants of the interfacial tension evolution model by minimizing a difference between the model and the interfacial tension measurements.
