Title: Method for identifying causes of faults in amperometric measuring cells
Inventor: STUDER MATTHIAS
IPC: G01N27/416
Filed: 1995-12-21
Abstract: The method identifies causes of faults in an amperometric measuring cell 1 which has at least an measuring electrode 2 and a counterelectrode 3 in an chamber 4 filled with a soluble electrolyte 6, and separated from the measurement sample being investigated by a permeable membrane 7, and a voltage source 10 of potential U, which produces a reference current i(t) between the electrodes 2, 3. The potential U is raised or lowered to a first potential U1 during a first period of time T1, and the resulting first sensor current i1 is measured and compared with the reference current. The first sensor current may be measured shortly after the adjustment to the first potential U1, or towards the end of the first period of time T1. During a second period, following the first period T1, the potential may be adjusted to a second potential which is less than U if U1 was greater than U, or greater than U if U1 was less than U. <IMAGE>

Abstract: Tandem mass spectrometry apparatus comprises a serial arrangement of an ion source (10), a first time-of-flight means (20, 80), a collision cell (40) to generate fragment ions and a second time-of-flight analyser (50). The second time-of-flight analyser comprises an ion mirror (51,52) which is arranged to produce a quadratic field along or at an angle to the optical axis of the apparatus. The first time-of-flight analyser may comprise a sequential S configuration of toroidal or cylindrical electrostatic analysers (70) or may comprise two electrostatic lenses (80,96) to either side of an ion mirror or may comprise an electrostatic lens (80). The first time-of-flight analysers thus comprise electrostatic field means for providing spatial focusing of ions in all three dimensions at or near the entrance to the ion mirror of the second time-of-flight analyser (50). The spatial focusing, concomitant with time focusing, is the essential requirement for the quadratic field mirror to give high resolution.

Title: Detecting unwanted substances in textile fibres from opened bales
Inventor: SCHLICHTER STEFAN
IPC: D01G7/10
Filed: 1997-08-07
Abstract: To detect unwanted substances in textile fibres flowing in air duct 9 a from a bale opener to a spinning preparation machine, cameras 15, 16 make reflected-light and transmitted-light images of the fibres, which images are evaluated electronically. Each camera receives light from sources 17 or 18, and 25 or 26, via mirrors 18 or 19. Image evaluating device 32 determines the degree of brightness and/or the colour of the fibres, and the degree of brightness of unwanted substances. This information is associated with the bale or group of bales from which the fibres are taken off. Then continuously measured values of fibre brightness and/or fibre colour, and of brightness of unwanted substances, are compared with at least one determined limiting value. When a value is exceeded, a display is initiated and/or flap 29 opened to remove unwanted substances.

Title: Electric power control system for a vehicle
Inventor: SHINOHARA KAZUHIKO
IPC: H02J7/14
Filed: 1998-02-12
Abstract: A vehicle has a first electric generator 1 driven by a shaft which is rotated by an IC engine of the vehicle, a second electric generator 2 which generates electricity from the energy in the exhaust gas from the IC engine, a rechargeable battery 6 connected to the generators 1, 2 and to a load 7, a judgement unit 4 which determines the driving condition of the vehicle, a judgement unit 5 which determines the charge storage condition of the battery 6, and a control unit 3 which controls the generators 1 and 2 as a function of signals from the judgement units 4 and 5. The arrangement improves fuel economy. A thermoelectric generator (Fig.2) and/or a turbine driven generator (Fig.4) may be used as the exhaust gas powered generator. The unit 4 determines whether the vehicle is stopped and idling, accelerating, moving at constant speed, or decelerating. The unit 5 determines whether the battery voltage is above a maximum level, below a minimum level, or between the minimum and maximum levels, and also determines whether current is flowing into or out of the battery 6. If the battery voltage is above the maximum level, both generators 1, 2 are rendered inoperative in all driving conditions. If the battery voltage is below the maximum level, the exhaust gas operated generator 2 is rendered operative in all driving conditions, and the shaft driven generator 1 is also activated for certain driving and battery conditions. If a detector 30 senses that the exhaust gas operated generator 2 is not functioning correctly, the generator 1 may be rendered operative in its place. Under certain conditions, generator 1 may act as a prime mover. A thermoelectric generator located upstream of a catalytic converter may also be used to heat or cool the exhaust gases.
