Abstract: The invention relates to apparatus and a process for mixing a gas/vapour with a process liquid comprising a material and a carrier liquid. The apparatus comprises a passage (10) having an inlet (14), an outlet (16) for a process liquid comprising the material, and an inlet (24) for introducing supersonic steam at a mixing zone (42). The profile of the mixing zone (42) can be varied to optimise mixing.

Abstract: A portable apparatus is disclosed for generating electrical power comprising a stator comprising a plurality of coils, coil units or coil segments for independently generating electrical power, wherein the stator comprises a printed coil laminate comprising a sheet of insulator material and a printed conductor comprising conductive ink printed upon the sheet of insulator material arranged to form the plurality of coils, coil units or coil segments and a reciprocator comprising a magnet, the reciprocator being responsive to vibrations and/or shocks and moves in that regard within the environs of the stator so as to generate electrical power. The apparatus is connectable to a portable electronic device so as to power that device and/or to a storage device for storing the generated electrical power.

Abstract: The invention relates to apparatus and a process for mixing a gas/vapour with a process liquid comprising a material and a carrier liquid. The apparatus comprises a passage (10) of polygonal cross section having an inlet (14), an outlet (16) for a process liquid comprising the material, and a nozzle (24) for introducing supersonic gas/vapour at a mixing zone (42) in a single plane.

Abstract: A node 100 for a communications system comprising a plurality of nodes is disclosed. The node 100 comprises a plurality of antennas each configured to transmit and/or receive a beam for communications with other nodes of a communications system. The at least one beam deflector is located in a housing 104,106 detachably attached to an external portion of the node 100. The or each beam deflector is located and arranged to deflect a beam transmitted and/or received at one of the plurality of antennas.

Abstract: An exercise apparatus for generating electrical power is disclosed comprising a rotor comprising a flywheel comprising a plurality of alternatingly poled magnets arranged radially towards a circumference of the wheel in a circumferential, circular or arc-like configuration and a stator comprising a disc or annulus comprising one or more radially arranged coil units arranged to have a circumferential, circular or arc-like configuration, wherein the stator comprises a printed coil laminate comprising a sheet of insulator material and a printed conductor comprising conductive ink printed upon the sheet of insulator material, wherein the printed conductor is arranged to form a coil unit. The flywheel rotates, in use, relative to the disc to cause the magnets to move relative to the coil unit(s) and generate electrical power in the stator.

Abstract: An apparatus for entraining a powder in a process fluid is provided. The apparatus (2?) has a process passage (22) having a passage inlet (24) connectable to a source of process fluid, and a passage outlet (26). A nozzle (30) opens into the process passage (22) intermediate the passage inlet (24) and passage outlet (26). The nozzle (30) has a nozzle inlet (32), a nozzle outlet (36) and a nozzle throat (34) intermediate the nozzle inlet (32) and nozzle outlet (36), where the nozzle throat (34) has a cross sectional area which is less than that of the nozzle inlet (32) and nozzle outlet (36). At least one first port (42?) opens into the process passage (22) adjacent the nozzle outlet (36), and an entrainment fluid supply chamber (38) is in fluid communication with the nozzle 30. A first powder supply chamber (44?) is connected to the first port (42?) by a first powder supply passage (46), wherein the powder supply chamber (44?), powder supply passage (46) and first port (42?) are coaxial.

Abstract: A remotely operated cutting mode shifting apparatus for use with a decoking tool of the type in which the cutting mode is changed by rotation of a diverter valve plate, has a shifter body adapted for mounting to the decoking tool and a control rod for engaging with the diverter valve plate. It includes a mechanism within the shifter body for rotating the control rod to drive the diverter valve plate to shift the cutting mode of the decoking tool upon release of cutting fluid pressure from the tool.
