Abstract: According to the present invention there is provided a process for producing an oligomeric product by the oligomerisation of at least one olefi?ic compound, by contacting the at least one olefinic compound with the combination of an oligomerisation catalyst and a catalyst activator. The catalyst activator is a compound which includes at least one halogenated organic group which is bound to one or more binding atoms selected from the group consisting of a group 5A atom and a group 6A atom, which one or more binding atoms are in turn bound to a central atom selected from the group consisting of a group 3A atom, and a group 3B to 7B transition metal atom. The oligomerisation catalyst includes the combination of i) a source of a transition metal; and ii) a ligating compound of the formula (R1)mX1(Y)X2(R2)n The invention also relates to a combination of an aligomerisation catalyst and a catalyst activator as set out above and to the use of such a combination in an oligomerisation process.

Abstract: A seal cartridge and a rotating nozzle assembly utilizing the seal cartridge are disclosed. The main seal member in the nozzle assembly is mounted as part of the seal cartridge. The seal cartridge is also easily removable from the rotating nozzle assembly without requiring the separate removal of the main seal member from the seal cartridge. This configuration allows a user to quickly install a new or rebuilt seal during an operation while minimizing or eliminating the necessity to manipulate small parts in the field.

Abstract: The invention provides a mixed heteroatomic ligand for an oligomerization of olefins catalyst, which ligand includes at least three heteroatoms, of which at least one heteroatom is sulfur and at least two heteroatoms are not the same. The invention also provides a multidentate mixed heteroatomic ligand for an oligomerization of olefins catalyst, which ligand includes at least three heteroatoms of which at least one is a sulfur atom. The ligand may also contain, in addition to sulfur, at least one nitrogen or phosphorous heteroatom.

Abstract: An air suspension system for a load bearing vehicle which includes a pair of air springs fluidly connected to a pair of auxiliary air reservoirs and to a main air reservoir. The system includes control valves which permit the air in the air springs to be exhausted therefrom to lower the vehicle frame without exhausting the air from the auxiliary air reservoirs.

Abstract: A fastener extractor is provided that includes an attachment end having an attachment means for connection to an extraction tool and a receiving end. The receiving end has an interior bore that angles inwardly towards the attachment end. The interior bore has a central axis and includes at least two arcuate grooves that extend along the interior bore towards the attachment end. The arcuate grooves curve radially and inwardly towards the central axis of the interior bore, with adjacent arcuate grooves forming sharp helically shaped ridges. A transition area is positioned between the attachment end and the receiving end and has a plurality of arcuate surfaces. Each of the plurality of surfaces corresponds to each of the arcuate grooves and projects inwardly from the corresponding groove towards the central axis. The interior bore is engageable over a fastener to be extracted.
