Title: Methods and apparatus for measuring flow velocity in a wellbore using nmr
Inventor: SPEIER PETER
IPC: G01R33/563
Filed: 2002-08-29
Abstract: The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.

Title: Malt beverages
Inventor: MENNEER IAIN
IPC: B67D1/00
Filed: 2001-05-31
Abstract: Beer in a barrel (1) is dispensed via supply line (2) to a dispense tap (3). A light source (5) provided between the barrel (1) and the tap (3) illuminates the beer with light having a wavelength of between 350-500 nanometers in order to cause the beer deliberately to become light-struck.

Title: Electrodeionisation process
Inventor: TURNER ANDREW DEREK
IPC: C02F1/461
Filed: 2003-06-25
Abstract: Ions can be removed from a fluid by an electrodialysis or packed-bed electrodialysis process, carried out between two electrodes (16, 18). To prevent ions that may have a detrimental effect from contacting the electrodes, an ionic barrier (25, 45) is arranged between the electrode and an adjacent channel, the ionic barrier comprising two spaced-apart membranes (C) selectively impermeable to the detrimental ions, and a liquid-permeable bed of ion exchange material (26, 46) between the two membranes. Water is passed through this bed (26, 46), to flush out any contaminants which may diffuse or leak out of the channel through the first membrane (C). The process is carried out by passing the fluid through at least one flow channel (12) packed with anion exchange resin beads (14), defined between membranes (A,B) of different ion-selective characteristics, anions migrating from the flow channel(s) (12) into transfer channel(s) (20).
