Patent GB-2274454-A (GB)
Title: Fluid treatment device and method
Inventor: JOSLIN CHRISTOPHER MICHAEL DAV
IPC: C02F1/00
Filed: 1993-11-15
Abstract: A fluid treatment device, especially for reducing or removing the effects of hard water, has a fluid inlet, a fluid outlet, and a cavity extending between the inlet and the outlet. A dielectric channel separator (preferably of plastics material, more preferably PTFE) is located in the cavity between the inlet and the outlet and extends at least part way along the cavity. The dielectric channel separator divides the cavity into a plurality of elongate channels which are mutually coextensive for at least part of their length in the direction of fluid flow from the inlet to the outlet and are at least partially bounded by dielectric material. A metallic channel separator, preferably of zinc, can also be provided to provide a degree of protection against corrosion. The channel separators are preferably configured to encourage turbulence in the fluid flowing through the device.

Title: Analog ramp generator with digital correction
Inventor: BLOOM ALAN R
IPC: H03K4/02
Filed: 1994-02-03
Abstract: An analog ramp signal used to control the frequency of a swept RF test oscillator 119 is generated by applying a fixed reference voltage to an analog integrator circuit 102. However, ramp accuracy is degraded by integrator gain error, drift, and nonlinearity. To correct for these errors, the analog ramp signal is periodically compared to a master digital ramp signal generated by a DAC 323 during the course of a sweep. The difference between the two ramp signals is scaled 349 and combined 330 with the reference voltage 300 to correct the slope of the analog ramp signal. An additional DAC 326 adjusts the gain of the correction loop. <IMAGE>

Filed: 1992-10-30
Abstract: A composite ceramic fibre (10) is made from a self-supporting composite polymeric fibre by the conjugate spinning of at least too dissimilar pre-ceramic polymers in shapes varying from cylindrical to ribbon-like, and pyrolysing the spun fibre to form a composite bilateral, core-sheath or matrix-fibril ceramic fibre having regions with ceramic compositions derived from each of the polymers, enabling physical and chemical characteristics to be widely varied for use as matrix reinforcements and other applications. A pyrolysis furnace (14) includes countercurrent controlled atmosphere gas flow for chemically stabilising or modifying the fibres.
Patent GB-2294539-A (GB)
Title: Waveguide pH sensor
Inventor: DEBOUX BRUNO
IPC: G01N21/85
Filed: 1994-10-12
Abstract: An apparatus for sensing pH comprises a sensor body (14) having a semi-permeable membrane (30) which, in use, contacts a fluid under test. A waveguide, e.g. an optical fibre (12) passes into the interior of the sensor body. The sensor body is filled with a fluid, such as methylene blue dye, in contact with the waveguide whose ionic attraction to the surface of the waveguide varies with pH, thereby varying the evanescent field absorption of radiation passing through the waveguide. Light from a laser light source (10) is transmitted along the waveguide and is detected by a light detector (16). Since the evanescent field absorption varies with pH, the intensity of light detected will also vary with pH. <IMAGE>

Title: Friction clutch with wear compensation
Inventor: LINK ACHIM
IPC: B60K17/02
Filed: 1994-11-03
Abstract: A friction clutch 1 has a flywheel 2 rotatable with a clutch housing 6, and a pressure plate 5 which is also axially movable by a diaphragm spring 7 to clamp friction linings 4 of a clutch plate 3 between the flywheel 2 and the pressure plate 5, and a device 23 to compensate for wear of the friction linings. The clutch 1 has one or more clearance indicators 13 each comprising an actuating lever 14 acting on the adjusting device 23, a sliding pin 17 axially movable in a bore 10 in the pressure plate 5, a clamping sleeve 9 for holding the pin frictionally in the bore, and an axial stop 18 to limit movement of the indicator 13 towards the flywheel. Each indicator 13 operates on wear of the friction linings 4 to provide a clearance between itself and the pressure plate 5, with the adjusting device operating the next time the clutch is disengaged to take up the clearance, so that the pressure plate 5 is moved axially relative to the spring 7 to compensate for wear. Alternatively the lever may act via the spring 7 (Fig 2) or may act through openings in the housing and the spring 7 (Fig 4). <IMAGE>

Patent GB-2295891-A (GB)
Title: Automatic anti-dazzle control of vehicle lights
Inventor: STEWART ALEXANDER
IPC: B60Q1/14
Filed: 1995-12-07
Abstract: A light control system for temporarily switching off a rear fog light when a rear-facing light sensor (18) is illuminated by the headlights of a following vehicle. With increasing illumination, the resistance of the sensor (18) falls and so increases the voltage at the junction (22) between the sensor (18) and an adjustable resistor (20) to a level at which a threshold-switching amplifier (24) changes output state. After a time delay set by circuit (28), a further amplifier (46) responds to open contacts (10) and so switch off the fog light. When the sensor (18) is no longer illuminated, the contacts (10) re-close after a short time delay. A daylight sensor (60) can provide over-ride of the anti-dazzle control. The anti-dazzle control circuit can alternatively or additionally be applied to temporarily switching off a front fog light and/or dipping headlights. <IMAGE>

Title: Digital communications device, method and systems
Inventor: MCANDREW PAT
IPC: G10L19/012
Filed: 1997-12-13
Abstract: A digital communications system has an air interface utilising speech coding with discontinuous transmission. A first device 100 is arranged to communicate over the interface and has a first memory 130 containing sets of parameters, each set describing a comfort noise profile. A second device 200 is arranged to communicate with the first device 100 over the interface, and has a second memory 230 containing substantially the same sets of parameters as the first memory. The first device receives speech signals from a speech source 110 and identifies one set of parameters in the first memory 130 which most similarly reflects background noise of the speech source. A signal is transmitted to the second device 200 indicating a memory location corresponding to the identified set. The transmitted signal is used by the second device 200 to read from a corresponding location of the second memory 230 a comfort noise profile for comfort noise generation in the second device. At least part of the sets of parameters stored in the memory 130,230 may be updated.
