Title: Normalising a photoacoustic signal in a biological measurement system
Inventor: MACKENZIE HUGH ALEXANDER
IPC: A61B5/00
Filed: 1998-03-09
Abstract: A biological parameter such as blood glucose is measured by directing laser pulses from a light guide (10) into a body part consisting of soft tissue, such as the tip of a finger (12) to produce a photoacoustic interaction (14). The resulting acoustic signal is detected by a transducer (16). A method of normalising the photoacoustic signal is provided comprising determining the dependence of the photoacoustic signal on the energy of the optical beam from a series of measurements at different energies. This improves the accuracy of the measurement system and compensates for the non linear absorption response of the sample to different excitation wavelengths.

Title: Oil/water separation utilising vortex and tilted plate separators
Inventor: LEWIS ALUN K
IPC: B01D17/04
Filed: 2002-01-30
Abstract: Oil is separated from water by means of a vortex separator followed by a tilted corrugated plate separator. The oil vortex 183 is developed in a vortex chamber 181 by means of spiral track 188, and oil is removed through outlet 185, 186. The residual oil/water mixture is passed (via conduit 208) to the bottom of a housing 195 containing one or more tilted corrugated plates 199. The or each plate has adjacent longitudinal grooves disposed between corresponding ridges, and the depth of each groove increases progressively along the length of the groove, simultaneously with a progressive decrease in the angle between the groove sides, as shown in Fig 1. The plates are arranged with the shallow large angle grooves at the bottom and the deep small angle grooves at the top. As the oil/water mixture passes up the underside of the grooves of the or each plate, oil droplets break free, float upwards within the housing and are transferred (via escape tube 198) to the surface of the oil vortex. Water depleted of oil is removed from the housing by pipe 205, which may contain a filter matrix to trap remaining particles of oil. The plates are preferably annular, and arranged in stacks, separated by barrier plates. In Fig 9, the conduit (20) taking residual oil/water to the bottom of the housing passes through the centre of the plates and the oil flows up through flexible tubes (70) supported by floats (71) to join the vortex.
