Abstract: A liquid/gas reactor comprises: a primary catalyst bed having an inlet and outlet end; means for supplying a primary feed stream to the inlet end; a secondary catalyst bed having an inlet and outlet end; means for supplying a secondary feed stream to the inlet end; means for collecting at least partially converted liquid product from the outlet end of the primary catalyst bed and recycling at least a portion of the liquid product to the inlet end of the primary catalyst bed and secondary catalyst bed; a separating wall between the primary catalyst bed and secondary catalyst bed; means for supplying a primary gas stream only to the inlet end of the primary catalyst bed; and means for supplying a secondary gas stream only to the inlet end of the secondary catalyst bed. A process for carrying out a gas/liquid reaction using the reactor is also disclosed.

Abstract: An electrical connector for an electrical connection within a fuel system, the electrical connector comprising first and second electrical connector pins, and an overmould for the first and second electrical connector pins. Each of the first and second electrical connector pins includes an external portion which projects from the overmould, an internal portion to which the overmould is applied, and a chamfered portion located between the internal portion and the external portion. The internal portion of each of the first and second electrical connector pins includes a region having a first dimension adjacent to the chamfered region and at least two axially spaced projections which extend radially from the internal portion beyond the region having a first dimension, adjacent ones of the axially spaced projections being separated axially by a region of the internal portion having a reduced dimension compared to the region having a first dimension.

Abstract: A process for the distillation of an aldehyde mixture comprising a straight-chain aldehyde and a branched-chain aldehyde is described in which the process comprises: supplying a feed comprising the aldehyde mixture to a first separation vessel; operating said first separation vessel at a first temperature and a first pressure such that separation occurs; recovering a first stream comprising the straight-chain aldehyde from said first separation vessel and supplying said first stream to a second separation vessel; operating said second separation vessel at a second temperature and a second pressure such that separation occurs; recovering a product stream comprising the straight-chain aldehyde and a second stream comprising high-boiling components from said second separation vessel, and supplying said second stream to a third separation vessel; operating said third separation vessel at a third temperature and a third pressure such that separation occurs; and recovering a third stream comprising the aldehyde mix

Abstract: The extraction process for removing metal salts from an organic hydroformylation reaction fluid (“HRF”) prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.

Abstract: A turbine diaphragm includes an annulus of static blades and an outer diaphragm ring surrounding the annulus of static blades and welded to the outer platforms. Each static blade has an inner platform, an aerofoil, and an outer platform. The inner platforms serve the function of an inner diaphragm ring, thereby reducing material and manufacturing costs. Furthermore, confronting edges of the inner platforms have an interference fit with each other and the aerofoils are in a state of torsional stress between the inner and outer platforms. The latter two features improve the dynamic characteristics of the diaphragm.

Abstract: A drum-type rotor carries an annular row of moving blades having root portions held within a slot in the periphery of the rotor. A turbine casing surrounds the rotor and carries a static blade assembly with an annular row of static blades which, together with the annular row of moving blades, constitutes an impulse turbine stage. The static blade assembly has a radially inner static ring confronting a periphery of the rotor with a seal acting therebetween. The static blade assembly has an outer static ring which has a substantially greater thermal inertia and stiffness then the inner static ring and is capable of sufficient radial sliding relative to the casing so as to accommodate relative thermal expansion and contraction of the outer static ring and the turbine casing.
