Title: Narrow angle scattering speckle interferometer
Inventor: VIRDEE MANOHAR SINGH
IPC: G01B9/02
Filed: 1996-02-05
Abstract: An interferometer for measuring sample size and displacement includes an He-Ne laser coupled into a probe part by an optical fibre feed, a beam splitter 14 which splits the beam between a target and a narrow angle scatterer 16. The beam splitter 14 also combines the reflected signals from the target and the scatterer 16 and feeds them to signal conditioning magnifying optics comprising a converging lens 20 and magnifying lens 22. The resultant magnified signal is received by a quadrature detector 26 comprising four optical detectors which obtains four detector signals which are subsequently combined to eliminate noise and dc offsets. Both movement of apertures and detectors can be used to vary the phase of the received signal. The narrow angle scatterer 16 is mounted on a piezo-electric transducer 18 so as to allow its movement and alignment.

Title: Actuation systems
Inventor: HARRIES DAVID ANTHONY
IPC: B62D5/07
Filed: 1995-11-07
Abstract: An actuation system particularly for vehicular use in which a pump (10b) draws fluid from a reservoir (10a) to supply one or more first consumers such as a steering valve (50). One or more second consumers such as a clutch actuator (12) are actuated via a solenoid valve (12a) from an accumulator (10c) charged by the pump. The solenoid valve connects the or each second consumer (12) to the accumulator or to the reservoir thus actuating the second consumers. At accumulator pressure levels below a predetermined charge level the flow of fluid to the or each first consumer (50) is restricted to a level sufficient to ensure effective operation of the or each first consumer whilst generating a back pressure sufficient to ensure charging of the accumulator. This flow restriction may be achieved by solenoid valve (12a) or by a separate charging valve (20).

Title: Chromatic dispersion compensation in wavelength division multiplexed light
Inventor: MIKAMI SATOSHI
IPC: H04B10/2507
Filed: 1997-01-10
Abstract: Wavelength division multiplexed optical signals with different wavelength dispersion are compensated for wavelength dispersion in a optical transmission line. Each multiplexed wavelength * small Greek lambda *1 - * small Greek lambda *n is selected by band pass filters 11-1 - 11-n. The selected optical signal for each wavelength is independently compensated for the wavelength dispersion by wavelength dispersion compensation sections 12-1 - 12-n. The wavelength dispersion compensation section of each wavelength has a optical fiber having a dispersion value with polarity opposite to that of the optical transmission line. Zero dispersion is attained for each wavelength * small Greek lambda *1 - * small Greek lambda *n as a whole, and transmission distance of wavelength division multiplexed optical signals can be extended.

Title: A fuel control system for an internal combustion engine
Inventor: WEBER GREGORY
IPC: F02D41/04
Filed: 1997-06-19
Abstract: A system for controlling fuel flow in an internal combustion engine (224) receives a command specifying a desired fuel flow rate from an electronic control module (222). The system generates a feedforward estimate of actuator current required to produce the desired flow rate. This estimate is combined with a fueling current offset value generated using a proportional-integral feedback controller (208). A differential pressure between the fuel rail and cylinder gas is converted, by surface interpolation based on a lookup table, to an estimate of actual fuel flow rate. The difference between this actual fuel flow rate and the desired flow rate is provided to the feedback controller (208) as an error signal. The feedback controller (208) uses different gain values depending on an operating mode of the engine (224) speed control and torque control modes).

Title: Reducing inkjet aerosol contamination using electrode(s)
Inventor: BRANHAM BRADLEY B
IPC: B41J29/17
Filed: 1998-03-23
Abstract: Aerosol contamination is reduced by inductively charging ink 70 (Fig. 8) within a printhead 38 (Fig.8) using a platen electrode 50 so that ink particles 78 (Fig.10), including aerosol particles (78c), ejected from a nozzle 68 (Fig.8) become charged. The platen also creates an electric field between the nozzle and a print medium 40, which interacts with the charged aerosol particles to help control their path. Depending on the charge of the particle and the polarity of the electric field the field either attracts the aerosol particle towards the medium, or it repels the particle towards the printhead where it can be collected and removed. A single electrode or network of electrodes can be used. The arrangement may be used in a carriage service station (80,Fig.11) wherein a spittoon electrode (84) diverts the aerosol particles received in the spittoon from the ink purged from a printhead (34).

Title: Location signing
Inventor: MOORE BARRIE PETER
IPC: G09B29/10
Filed: 1998-03-25
Abstract: A system of signs to enable an observer to establish location in a particular area is based upon a co-ordinate grid with a significant landmark at the centre of the grid. Thus, every sign in the system will carry an icon representing the landmark and a spotmark with either its grid reference (Drawing 2, not shown) or the relevant numbered gridlines (Drawing 3, not shown). The system is diagrammatic so that there is no regular one-to-one mapping of distances, thus the spotmarks are numbered in sequence from the central landmark; conventional arrows may indicate routeing directions, but obviate the need for compass points to be shown.

IPC: B30B15/00
Filed: 1998-10-15
Abstract: A hydrodynamic oil film system is described for developing a lubricant film between a flywheel (16) and an associated stationary bearing (14) during press machine operation. Hydrostatic bearing pads (24) formed in the inner bearing surface of the stationary bearing are used to receive pressurized fluid. A hydrodynamic effect is produced during rotation of the flywheel enabling fluid transmitted into the hydrostatic bearing pads to be provided within the clearance between the flywheel and the stationary bearing. In another aspect, an oil film (52) is produced between the keyed sections of the stationary bearing (14) and an adjacent bearing support block (22) to which the stationary bearing is interengaged for anti-rotational purposes, thereby preventing pounding out of the material from the key surfaces.

Title: Liquid Chromatograph
Inventor: KITAOKA MITSUO
IPC: G01N30/34
Filed: 1999-06-18
Abstract: The objective of the present invention is to automate introduction or substitution of a mobile phase in a liquid chromatograph without increasing the cost. When a signal for filling up with or substituting a mobile phase is externally transmitted to a control part (40), the control part (40) switches a valve (26) for connecting a channel from a pump part (2) to a sampling needle (36) through a sampling loop (24) and moves the sampling needle (36) toward a drain port (38). Thus, a channel is formed through a mobile phase container (16) # a pump (10) # the switching valve (26) # the sampling loop (24) # the sampling needle (36) # the drain port (38). In this channel state, the control part (40) drives the pump (10) at a high speed for substituting the channel connecting the pump (10) and the sampling needle (36) by a desired mobile phase.
