Title: Cable identification and routing confirmation using a thermal technique
Inventor: HOBBY DAVID LESLIE EDWARD
IPC: H01R43/00
Filed: 1990-08-07
Abstract: Individual cables of an enclosed cable loom are easily identified by 'tagging' with a thermal marker.

Title: Automated speech recognition system
Inventor: WHITE GEORGE M
IPC: G10L15/14
Filed: 1990-12-10
Abstract: A speech recognition system reduces ambiguity by taking segments of electrical signals derived from unknown verbal utterances and time aligning them with reference signal segments derived from known verbal utterances using Hidden Markov Model techniques, 66, so as to produce a scored list of tentatively identified works or phonemes corresponding to the time-aligned segments. The list of tentatively identified words or phonemes are then rescored using artificial neural net techniques, 70, to produce an output signal corresponding to a finalized list of words determined to be the most likely correct interpretation of the unknown verbal utterances. Alternatively, only ambiguous portions of the list of words tentatively identified by HMM techniques are input to the artificial neural net for rescoring. <IMAGE>
Patent GB-2239985-A (GB)
Title: Method and apparatus for surface analysis
Inventor: KINGHAM DAVID RICHARD
IPC: H01J49/16
Filed: 1990-12-14
Abstract: Organic material present in a surface region (5) of a sample (1) is analysed by locating the sample in an evacuable chamber (2). generating and directing an energetic beam (4) of particles or photons onto the sample to remove at least some organic material into a spatial region (7) proximate to the surface region, generating and directing non-coherent ultra-violet radiation (14) into the spatial region containing the removed sample to photoionize organic material therein, and mass analyzing the resultant ionized species. The ionising ultra violet radiation source 13 may supply radiation in the range 11.7 - 48.4 ev when charged with Ar, Ne or He. As shown, the ionisation volume 7 is bounded by electrodes 9, 10, 11 held at a common potential whereby the potential at which the ions are formed therein can be controlled. By maintaining the sample at a higher potential than the region 7, the ions formed by photoionisation can be preferentially analysed by providing, between the ion source and the analyser, an energy filter which discriminates against the higher energy ions produced by direct impact of the energetic beam on the sample. <IMAGE>

Title: Dual brake pressure proportioning valve assembly
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/26
Filed: 1991-01-11
Abstract: A brake pressure proportioning valve assembly (1) comprises first (2) and second (3) normally open valve sets each for controlling communication between respective associated inlet (4A, 15) and outlet (4, 16) chambers, the first valve set (2) being controlled by a brake pressure responsive piston (6) and a deceleration responsive member (7) while the second valve set (3) is controlled by a pressure responsive piston (14) and the respective pistons (6, 14) are biased apart towards the valve open positions by a common compression spring (9). The force applied to the piston (14) by the spring (9) is thus determined by the position of the piston (6) so that the pressures at the outlet chambers (4, 16) are maintained equal. The valve provides deceleration responsive brake pressure reduction to both the rear brakes of a dual braking system without the need for two separate deceleration responsive members. In another embodiment the inlet pressure (Pf2) of the first valve (2) is also applied to the right hand end of the second valve piston (14) which extends beyond the outlet chamber (16). <IMAGE>

Title: Ion detector
Inventor: EVANS SYDNEY
IPC: H01J49/02
Filed: 1991-02-05
Abstract: The ion detector for use with a mass analyser comprises a microchannel plate 5 having a first face 6, coincident with the focal plane 2 of the analyser, and a rear face 7. An apertured mask plate 8 is disposed adjacent to the rear face of the plate so that electrons produced in the plate in response to ions incident at each of preselected positions in the focal plane pass through a respective aperture 9, 9', 9'' in the mask plate for detection by a respective collector electrode 10, 10', 10'' after amplification in the microchannel plate. In use in a mass spectrometer only ions incident at the pre-selected positions are detected corresponding to one or more pre-selected masses. The mask can be changed in order to produce varying spectrum as required. Channels, in the microchannel plate may be of curved, 'V' or 'chevron' configuration. <IMAGE>
Patent GB-2252494-A (GB)
Title: Collapsible seats
Inventor: READE DAVID ROBERT
IPC: A47C4/24
Filed: 1991-02-09
Abstract: As a seat assembly is moved from the closed condition shown to an open condition, legs 3 and 4 are pulled apart about pivot 5 and this causes the seat frame 2 to drop down. In a final movement the leg 4 is pulled rearwardly to a further extent thus causing a hook formation 12 to locate about a post 11 on the seat frame. This locks the assembly and prevents the seat frame 2 (and seat 1) from being raised or lowered until the leg 4 is moved forwardly again to release the locating post 11 from the hook formation 12. <IMAGE>
