Title: Apparatus for low pressure liquid chromatography
Inventor: HJELM NILS MAGNUS
IPC: G01N30/86
Filed: 1992-01-06
Abstract: Apparatus for low pressure liquid chromatography which is particularly suitable for the testing of body fluids and in particular blood, comprising means for passing a sample through a chromatography column 4 containing a packing material so that a constituent of the sample is retained by the packing material and passing a buffer solution having a varying concentration through the column. When the concentration of the buffer solution reaches a particular level, the constituent will be disassociated from the packing material and flows out of the column through a detector. The detector measures the light absorption of the fluid and by relating the time varying light absorption of the fluid to the time varying concentration of the buffer solution it is possible to identify the constituent. The column is releasably held between two mountings 43, 45 at least one of which is movable between a position allow insertion and removal of the column and a position in which the column is held squeezed between the mountings. Mounting 45 is movable by means of cam 48. When the column is held tight, the mountings are fluid sealed to it by seats e.g. 46, 46A. <IMAGE>

Title: Image anomaly detector
Inventor: LUTTRELL STEPHEN PIERS
IPC: G01N21/898
Filed: 1992-02-10
Abstract: An anomaly detector 10 comprises a camera 12, two modules U1 and U2 forming first and second stages of the detector respectively, and a display 14. The anomalies are highlighted through the use of a probability transformation, in which the value of an individual pixel is replaced by its occurence probability derived from other pixels associated during a training process. Prior to use the detector 10 is trained to detect anomalies in an image texture of interest. A training image 18 of the texture is viewed by camera 12 and stored. Pairs of pixels in the stored image are associated, after which their co-occurrence probabilities are determined and they undergo processing by training transputer T1; the latter fills mapping look-up table M1, which provides a data transformation for associated pixel signals prior to input to, and further association in the second module U2. The training image 18 is replaced with another image 20 of the same texture, which is then processed by detector 10. This produces an anomaly image in which positions where anomalies occur in the image are indicated on the display 14. <IMAGE>
Patent GB-2266017-A (GB)
Title: Sigma-delta converter
Inventor: ADAMS FRANCIS NEIL
IPC: H03M3/04
Filed: 1992-04-10
Abstract: In a sigma-delta converter, the digital output converted to analogue form is subtracted, 1, from the analogue input and the differences are integrated in a filter 2 before being passed to the quantising element 3. The quantising noise of the analogue-to-digital converter 3 is thus shaped to produce a minimum in the signal passband. The depth of the minimum can be increased by adding extra filter stages 2, but instability results unless the analogue-to-digital converter 3 is multi-bit. Linearity of reconversion to analogue form requires that the digital to analogue converter 5 must be single bit, which necessitates a second quantising means 6 at which truncation takes place. In accordance with the invention, the quantisation noise of the latter is suppressed by a noise cancellation path 8 at which the quantisation noise of the truncation quantising means 6, is subtracted digitally in the forward path e.g. at the node 9 to allow the benefit of higher order filters to be used without instability i.e. allowing a greater proportion of the sampling bandwidth to be usable for signals. <IMAGE>

Title: Antenna system
Inventor: ASHLEE KIEREN
IPC: H01Q21/30
Filed: 1993-06-19
Abstract: In a method of combining a series of radio frequency signals having different frequencies, the signals are fed to the respective inputs of a first set of hybrid power combiner units 31, 32 and the outputs from this first set of units are optionally fed to further sets of such units 33, 34. The signal outputs of the final set of units are fed to the radiating elements 35 - 38 of an antenna array. In a modification, a pair of signals is fed to a single hybrid power combiner unit and each output of the unit is fed to a separate antenna. Hybrid combiner units may be branch line couplers formed from a combination of series and shunt transmission line sections in microstrip form or they could be hybrid ring couplers. The radiating elements in the antenna array are preferably arranged to provide a uniform output signal in the azimuth plane by stacking or spacing around a structure in opposite azimuth directions. In a most preferred embodiment the antennas in the array are used for both transmission and reception and are fitted with a duplexor so that transmitted and received signals do not interact. <IMAGE>
Patent GB-2279745-A (GB)
Title: Acoustic transmitting and receiving unit.
Inventor: CROWTHER PAUL ANDREW
IPC: G01S15/931
Filed: 1993-07-09
Abstract: An acoustic transmitting and/or receiving unit (3) for transmitting and/or receiving acoustic energy through a planar member (2) is formed by an acoustic driver (7, 8, 9) acting on the planar member through an aperture (5) in a plate (4). The plate is attached to the planar member across its surface and the plate has greater stiffness than the planar member. In the transmitting mode, transducer (8) bends in oscillating motion, causing the portion of the planar member (2) in front of the aperture (5) to move in and out, thereby generating acoustic signals in the air which then radiate outwards. In the receiving mode, when acoustic signals strike the bumper bar (2), oscillations of the portion of the bumper bar (2) in front of the aperture (5) drive transducer (8), thereby generating electrical signals. <IMAGE>
Patent GB-2281671-A (GB)
Title: Monopulse receiver
Inventor: STEVENS MICHAEL CHARLES
IPC: G01S13/44
Filed: 1993-08-24
Abstract: In a monopulse radar system, the azimuth angle from a look direction to a target, is found by receiving the target's reply as signals both at 0 DEG  elevation above ground, and from a higher elevation. At 0 DEG  elevation, both sum  SIGMA 1and difference  DELTA 1 signals derived; at the higher elevation, a difference  DELTA 2 signal is determined. The signals are used to determine azimuth angle, corrected for non-zero target elevation: the ratio  DELTA 1/ DELTA 2 of the difference signals is sensitive to target elevation; this is used in combination with the ratio  SIGMA 1/ DELTA 1 of signals at 0 DEG  elevation to determine (by means of a look-up table or comparable calculation) the target's azimuth correctly, independent of its elevation. <IMAGE>
