Abstract: The present invention discloses a method for preparing an activating support and its use to activate metallocene or post-metallocene catalyst component for use in the oligomerization and polymerization of ethylene and alpha-olefins.

Abstract: The present invention relates to the covalent anchorage of non-coordinating anions on mineral supports to prepare activating supports for the polymerisation of ethylene and alpha-olefins and wherein the activating species is provided by a phosphonium-borate or phosphonium alane pair. The invention also discloses the concomitant covalent anchorage of zwitterionic systems containing both the non-coordinating anion and the counter cation parts of the activating supports.

Abstract: The present invention discloses a method for separating tethered functional organo-chains, through their dilution with tethered non-functional organo-chains, in the presence of soluble molecular derivatives that are able to self-assemble and to interact with the functional organo-silane.

Abstract: The present invention discloses a method for supporting a transition metal complex and the resulting supported catalyst component which is characterised in that the metallic sites are kept away from one another and kept away from the surface of the support.

Abstract: A fuel pump module and carbon canister assembly adapted for mounting within a fuel tank. A fuel pump module has a flange and a body carried by the flange. A carbon canister is attached to the body of the fuel pump module and is adapted for an inclined orientation with respect to the flange of the fuel pump module. The fuel tank may include a bottom and a top having an opening through which the fuel pump module and carbon canister assembly may be inserted. The carbon canister may be adapted for resting on the bottom of the fuel tank once inserted therein.

Abstract: The invention provides a system for feeding fuel additive on board a motor vehicle, the system comprising an additive tank and a metering pump suitable for sucking in a controlled quantity of additive from said tank, under the control of control means in order to deliver said quantity into the fuel of said vehicle. The system is remarkable in that said metering pump is integrated in a fuel-drawing module placed inside a fuel tank of the vehicle. This saves space. The invention is applicable to the automotive industry.

Abstract: The invention concerns a motor vehicle fuel drawing assembly comprising a housing (200) having a ring-shaped chamber (220) and a filter (100) arranged in said ring-shaped chamber. The invention is characterised in that it comprises at least a plastic annular lip (126, 136), cast in one single piece linked to the housing (200) or to the filter (100), made of a material capable of being elastically deformed, and shaped along an oblique direction relatively to the axis O-O of the filter (100) and the housing chamber (220), such that said lip (126, 136) is urged to rest, with elastic deformation, and along a direction with tangential components by its free end (127, 137), against the surface opposite (286, 296), the other surface of the filter (100) or of the housing (200) arranged substantially transversely to the axis (O-O) of the filter (100) of the housing (200) chamber (220) to ensure tightness at that level between the filter (100) and the housing (200).

Abstract: The present invention relates to a fuel-drawing assembly for a motor vehicle tank, the assembly comprising a main pump (110) associated with a pressure regulator (170) and a reserve bowl (150) fed by a jet pump (160) and from which the main pump (110) draws fuel, the assembly being characterized by the fact that the jet pump (160) is integrated in the outlet from the pressure regulator (170), and that the jet pump and regulator (160 and 170) subassembly formed in this way is secured to a module (100) comprising the main pump (110) and the reserve bowl (150), a portion of the housing (171) for the pressure regulator (170) being integrated in the wall constituting the reserve bowl (150).

Abstract: A fuel gauging system for a motor vehicle fuel tank, including a housing (100) supporting a resistive element (200), an arm (300) pivotally mounted on the housing (100) and comprising at least one cursor (350) engaging the resistive element (200), and a lever (400) provided with a float connected to the arm (300) for monitoring the movements thereof. The system includes a housing (100) and an arm (300) which comprise complementary rotational guides (120, 310) and structure (316, 317, 318, and 319) to enable translation of the arm (300) on the housing (100). The arm (300) is combined with an L-shaped lever (400) so that one of the sections (420) defines the pivot axis of the device.
