Patent GB-2185308-A (GB)
Title: Optical waveguide material sensor
Inventor: WILLSON JOLYON PETER
IPC: G01N21/59
Filed: 1986-01-10
Abstract: A biochemical sensor device comprises a planar monomode waveguide 11 one surface of which is coated with a metal film 13 which in turn is coated with a dielectric film 14. The dielectric is as elective absorber of a material to be sensed. Light propagated through the waveguide interacts with surface plasmons in the metal film, the degree of interaction being a function of the electric field conditions adjacent the metal film. The attenuation is measured by a photodetector 16. A waveguide supporting two guided modes, only one of which exhibits resonance, may be employed, the non-resonant mode providing a reference signal. <IMAGE>

Title: Dosing and blending unit for food/ plastics processing
Inventor: BECKHURST TREVOR ALAN
IPC: B01F15/02
Filed: 1986-03-25
Abstract: The dosing and blending unit has a mixing bowl (11) having a lid which at its centre supports a drive motor (10) for an agitator (12).

Patent GB-2223577-A (GB)
Title: Seed testing
Inventor: DRAPER SIMON ROBERT
IPC: G01N33/52
Filed: 1988-02-17
Abstract: A method of testing a batch of seeds for viability comprises selecting a representative sample of seeds from the batch; treating the seeds in the sample with a tetrazolium salt to produce staining of living cells and tissues; examining treated seeds in turn and classifying each seed as viable or not depending on the observed staining pattern and recording the results for successive seeds until sufficient seeds from the sample have been classified to classify the batch as viable or not using a probability ration test, or until all seeds in the sample have been examined; and classifying the batch appropriately. The invention is based on use of the statistical technique of sequential sampling, in which the examined sample size depends upon the results of successive seeds for the sample. Substantially fewer seeds generally need to be examined than in a conventional tetrazolium test, so the method of the invention can be carried out significantly more quickly than conventional tetrazolium testing methods, while producing comparable accuracy. In another aspect, seeds are soaked in water at about 40 DEG C for at least 2 hours prior to tetrazolium staining, in place of a conventional overnight soak in water at 30C, reducing test time.

Title: Method of manufacturing an infra-red radiation source
Inventor: JONES WILLIAM
IPC: H05B3/44
Filed: 1989-05-25
Abstract: A glass tube with an electrical conductor running through it is packed with ceramic powder material and sealed at both ends. The electrical conductor is then energised to a temperature sufficient to sinter the ceramic powder, with the electrical conductor being sacrificed and defusing into the sintered material so that this sintered material subsequently provides an electrical conducting path within the tube. The tube can subsequently be energised by passing electric current through it so that the regions of conductive sintered ceramic in the tube glow red. <IMAGE>

Title: Security device
Inventor: EZRA DAVID
IPC: G06V10/88
Filed: 1989-05-31
Abstract: A security device comprising a substrate (1) on or in which is provided a radiation scattering structure derived from a master member (7, Fig. 3), the radiation scattering structure causing an incident, coherent beam of radiation to scatter in a random manner whereby the scattered beams interfere to generate a speckle pattern.

Title: Mud saver valve with replaceable inner sleeve
Inventor: BAILEY THOMAS F
IPC: E21B34/06
Filed: 1989-10-30
Abstract: A mud saver valve (10) for insertion within a drill string (12) retains mud in a drill pipe and prevents a mud column from flowing past the valve when pumping is interrupted. A body (20) of the valve has a tubular body and a piston (22) having an axial passage (34) for the flow of drilling mud. This piston is biased within the body by a spring (36) and axially movable in response to the mud flow. A check valve plug (24) is disposed within the bore which may be removed to run wireline tools. The plug is seated within a reduced diameter portion of the body and includes a replaceable inner sleeve (40) which engages the piston to prevent flow through the valve. The inner sleeve is replaced as it becomes worn due to the erosive forces of the drilling mud. <IMAGE>

Title: Common rail fuel injection system
Inventor: CROWLEY PATRICK JOSEPH
IPC: F02M55/00
Filed: 1991-04-09
Abstract: A common rail fuel injection system for an I.C. engine consists primarily of a high-pressure fuel pump (24 or 26), nozzles (40, 42, 44 or 52, 54, 56) and a corresponding rail (28 or 30) having a substantially constant pressure situated between the fuel pump and the nozzles. An electronic control system 10 controls the fuel pump and the nozzles. A normally closed solenoid operated inlet valve (82 or 84) is held open during the intake stroke for a time determined by the control system. The high pressure pump (28 or 30) has a port opening into the pumping chamber at a point exposed when the pumping piston 134 is near bottom dead centre, the port being connected to receive fuel which leaks from the nozzles (40, 42, 44 or 52, 54, 56). The pump is arranged to add leakage fuel to each stroke output without the necessity for routing this leakage fuel through the primary supply. This reduces the total amount of fuel pumped and improves metering accuracy. <IMAGE>
