Patent GB-2293989-A (GB)
Title: Arrangements for the aftertreatment of exhaust gases
Inventor: STUTZENBERGER HEINZ
IPC: F01P3/12
Filed: 1995-10-11
Abstract: The invention proposes an arrangement for the aftertreatment of exhaust gases from a compression-ignition internal combustion engine, in which, to improve the operation of a reducing catalytic converter, a reducing agent is injected into the exhaust gas fed to the catalytic converter (2). Injection is performed by means of an electrically controlled motoring valve (6) which is combined in a common housing with a control valve (5). This control valve serves for the controlled introduction of compressed air supplied, in which a quantity of reducing agent made ready by the motoring valve (6) is prepared and introduced intermittently into the exhaust gas. This serves, in particular, to avoid urea deposition and clogging in the metering valve and the control valve and for the optimum preparation of the reducing agent introduced. <IMAGE>

Title: Improving the optical intensity induced damage limit of active optical crystals and lasers
Inventor: DEMARIA ANTHONY JOHN
IPC: H01S5/16
Filed: 1996-07-25
Abstract: In an optical arrangement (8), passive optical elements in the form of windows (12,14) are positioned against optical entrance and exit surfaces of an active optical element (10) and held in place with end support members (22,26) and fasteners (30,32,34,35). The windows (12,14) are formed of a material such as GaAs, GaAlAs or ZnSe having a higher optical damage threshold than the active optical element (10) and may have anti-reflection coatings. Heat deposited near the surface of the active optical element can flow into the window material and be removed from the locality. In an arrangement suitable for producing second harmonic generation where the active optical element (10) is a non linear crystal of AgGaSe 2 suitable windows (12,14) would be made of GaAs with a thermal diffusivity many times greater than AgGaSe 2 . By allowing a higher pump power to be used without damaging the non-linear crystal the efficiency of the second harmonic generation process may be raised. Application of the invention to a semiconductor laser 106 is also described, the exterior surfaces of the windows (108,110) in this case being reflective and partially reflective respectively.
Patent GB-2305277-A (GB)
Title: A lossy data compression method
Inventor: LONNON GREGORY
IPC: H04N1/411
Filed: 1996-08-19
Abstract: In a method for data compressing a raster-arranged pixel image (101), data segments of the image are compared to data segment patterns in a table to determine a classification of the image, where the classification is either clustered or dispersed. After the image is classified, a lossy compressing procedure (102) is performed by reducing each n x n-bit block of the pixel image to an m-bit segment (count of black dots). The lossy compressed image (103) is accompanied by a classification indicator. Next, the lossy compressed image (103) is compressed with a lossless compressor (104) such as LZS8. Decompression is accomplished by decompressing (104) the compressed lossy compressed image (105) with a lossless decompressor (104) to recover the lossy compressed image (103). A lossy decompressing procedure operates on the lossy compressed image (103) by employing the m-bit data segment to access a stored n x n bit matrix from a pair of matrix tables in accordance with the classification indicator. One table is n x n-bit images classified as clustered and the other table is n x n-bit images classified as dispersed.
Patent GB-2313650-A (GB)
Title: Thermocouple bypass
Inventor: JOSIF GEORGE
IPC: F23N5/10
Filed: 1996-10-11
Abstract: At start-up knob 4 is depressed to lift valve disc 9 from seat 8 to allow gas to flow from a conduit 1 to an appliance via outlet 16. Upon release of the knob the valve is held open by an electromagnet since a timing unit 25 applies a current to a coil 13 of the electromagnet. The timing unit applies a current for a predetermined period of time. If the thermocouple is heated sufficiently during the time period it will provide sufficient current to coil 13 to retain the valve in the open position when the timed current is released. The timer supplies a current which is sufficient to hold the valve open but which is not sufficient to move the valve from the closed to the open position.

Title: A motion video compression system with buffer empty/fill look-ahead bit allocation
Inventor: HOANG DZUNG TIEN
IPC: H04N19/00
Filed: 1997-01-08
Abstract: Systems are provided for allocating bits to pictures in accordance with the bit allocation constraints for operation at both constant and variable bit rates. The encoding complexity of each picture is modeled based on its spatial and temporal properties. Based on the modelling, a number of bits is allocated in advance to each picture. Each picture is then compressed according to the bits allocated. Based on the difference between the achieved and desired bit rates and on the availability of computational resources, a second pass or multiple passes may be performed to improve the coding.

Title: Head lamp device for vehicles
Inventor: NOJIRI RYUJI
IPC: F21V7/00
Filed: 1997-07-04
Abstract: A head lamp device for a vehicle comprising a passing beam lamp unit 1, a driving beam lamp unit 2, and optical fibres 5 conducting light from unit 1 to unit 2. A discharge lamp 12 serves as a light source for passing beam unit. A reflecting mirror 13 disposed ahead of the discharge lamp reflects directly forwardly emitted light from the discharge lamp and concentrates the light on a condensing portion 14. Light conducted by the optical fibres 5 serves as the light source for the driving beam unit. A shutter mechanism 6 controls the passing of the light conducted to the driving beam unit. The use of a single discharge lamp to provide both passing beam and driving beam functions reduces the cost of providing lamps and lamp circuits for the head lamp, equalises the colour temperatures of the passing and driving beams and improves the balance of luminous intensity distribution, and forward visibility.

Title: Liquid crystal sensors for sensing analyte molecules
Inventor: NICHOLAS PAUL
IPC: G01N21/59
Filed: 1997-12-19
Abstract: A device for sensing one or more analyte molecules comprises a membrane (1) whose surfaces are rendered electrically conducting; a liquid crystal material or liquid crystal blend impregnated within the membrane; a light source; a light sensor; and light guides (8) between the light source and one surface of the membrane (1) and between the other surface and the light sensor, whereby the light sensor senses light transmitted through the membrane (1) from the source via the light guides (8). The light transmitted through the liquid crystal is affected by the presence of particular molecules in a liquid or gas passed through holes (7) into a space adjacent the membrane. Different sinusoidally modulated voltages applied across the two surfaces of the membrane change the response of the liquid crystal and render the device sensitive to different molecules. Further optical fibres (9) form a reference channel where the liquid crystal is not exposed to the analyte.
