Abstract: A fast rechargeable battery assembly and a battery recharging equipment configured to recharge a battery in a very short period of time, by using a plurality of independent power supply units which recharge simultaneously a battery split in a plurality of independent battery modules, each one of these having a plurality of battery cells connected to a pair of module independent terminals positive and negative, which are direct connected to an independent power supply unit—in recharging mode, and in supplying mode all of these being connected to a battery main terminal. This functionality is realized for on-board recharging by using a contact plate and a plurality of switches, changeover witches and command switches, and for off-board recharging by using a recharging and a supplying contact plate.

Abstract: The invention provides a new design of an intelligent pooling vehicle and trailer system equipped with an intelligent pooling vehicle and an intelligent electric powered trailer capable to improve the efficiency of the system, avoid off-tracking and make the system more user friendly. The rear powered tires train is capable to turn around a pivot, taking different positions with respect to the trailer. The independent electric motors on each tire of the trailer rear tires train provide additional power to the vehicle and steering capability of the trailer rear tires train. This allows better control of the rear of the trailer and instead to be only pull by the truck, the trailer may be driven by it self, by using different speeds on each of the two tires, avoiding accidents and helping back parking and driving. The system may work in automatic or manual mode.

Abstract: The invention provides a battery equipment and fast recharging station capable to recharge the battery in a very short period of time, due to the new design of the recharging stations, battery chargers, inlets and battery connectors. This new design consists in the use of a plurality of battery power supply units per recharging station, which is capable to connect all these power supply units simultaneously to a battery, via a plurality of battery chargers and inlets. For recharging, the battery has many terminals connected to all power supply units of the station and means to switch it from recharging to supplying mode. Bigger the number of power supply units, shorter is the battery recharging time and smaller the area of the recharging station. May be used for on-board recharging electric vehicles, or off-board recharging battery for bicycles, motor-cycles, portable tools.

Abstract: A method of deburring channel inlet edges inside a cavity of a gas diffuser case is disclosed. The diffuser case has a plurality of channels each having an inner surface and an inlet edge defining an inlet of the channel. The surfaces of adjacent channels co-operate to provide said inlet edge therebetween. The inlet edges of the channels are provided in an inwardly facing circular array around a central axis of the gas diffuser case. The method comprises: inserting a tool head having at least one nozzle in the cavity of the gas diffuser case; and then ejecting abrasive particles from at least one nozzle towards at least one of the channel inlet edges of the gas diffuser case to at least one of decrease a radius of at least one said edge and improve a smoothness of at least one said surface.

Abstract: A centrifugal compressor includes an impeller and a diffuser. The impeller has an inner integral hub with vanes thereon, is adapted to rotate within an outer shroud about a central longitudinal axis, and has a defined hub-to-shroud distribution of fluid exit angles. The diffuser, downstream from the impeller, comprises a plurality of circumferentially spaced discrete passages at least partially defining fluid paths through the diffuser, and angled such that adjacent discrete passages intersect each other to form an annular semi-vaneless diffuser inlet space. The discrete passages downstream of the semi-vaneless space each have an inlet therefrom and an outlet with a greater cross-sectional area than the inlet. The intersection of the annular semi-vaneless space and each discrete passage defines a leading edge thereof.
