    Abstract: Process for the conversion of synthesis gas to liquid hydrocarbon products by contacting, in a slurry reactor, synthesis gas at an elevated temperature and pressure with a suspension of catalyst in a liquid medium, introducing a low boiling solvent into the slurry reactor, vaporising at least a portion of the low boiling solvent in the slurry reactor, withdrawing from the slurry reactor, a gaseous stream comprising unreacted synthesis gas and vaporised low boiling solvent, cooling at least a portion of the gaseous stream to a temperature at which liquid condenses out so as to form a two phase mixture of gas and condensed liquid, and recycling at least a portion of the gas and at least a portion of the condensed liquid to the slurry reactor.

    Abstract: A process for reacting in a fluid bed reactor at least one oxidisable reactant with molecular oxygen in the presence of a catalytically active fluidised bed of solid particles. In the process a molecular oxygen-containing gas having an oxygen concentration greater than that of air is introduced into the fluidised bed whilst the fluidised bed is maintained in a turbulent regime. The process is suitable for oxidation, ammoxidation and carboxylation processes, including the production of maleic anhydride, acrylonitrile, ethylene, acetic acid and vinyl acetate.

    Abstract: A surgical tool having proximal and distal ends and adapted to transverse a curved passageway comprises an end effector disposed on the distal end of the surgical tool, the end effector having a first body section and a second body section and a releasable connector joining the end effector first body section with the end effector second body section. The connector is operable to reversibly engage the first and second end effector body sections in a first fixed position and in a second movable position. The surgical tool further comprises an actuation device for moving the first and second end effector body sections from the first fixed position to the second movable position. The end effector is adapted to maneuver through a larger radius of curvature in the second movable position than in the first fixed position.
