IPC: G01D5/20
Filed: 1996-10-16
Abstract: In a differential transformer which includes a primary coil 32 for excitation and first and second secondary coils 33,34 for detection, all wound on a non-magnetic (e.g. ceramic) bobbin, and a magnetic core 36 movable in an axial direction to vary the differential output voltage from the secondary coils, the latter are each wound from at least two wires A,B which are of different temperature coefficient of resistivity and the relative wire lengths are so adjusted that a measuring device using the transformer may have zero measurement error over a range of temperatures. Alternatively the coils may be wound from a single wire of low or negative temperature coefficient. A device is described which measures the diameter of a workpiece (W, Fig.3) by means of feelers (12,13) respectively coupled to the bobbin and core.

Patent GB-2311896-A (GB)
Title: Detectors for high energy radiation
Inventor: ROBBINS MARK STANFORD
IPC: G01T1/02
Filed: 1997-04-04
Abstract: A detector for high energy radiation such as X-ray radiation or gamma radiation comprises a layer 1 of scintillator material, an intermediate layer 2 and a solid state detector array 3 located behind them. The intermediate layer 2 has an atomic number which is less than that of either the scintillator material or the radiation sensitive regions of the detector. Hence, secondary electrons produced at the detector region move to the intermediate layer, reducing the dose delivered by X-rays to the sensitive regions and prolonging the life of the detector. The scintillator layer may be of gadolinium oxysulphide and the detector array, e.g. a CCD structure, is preferably of silicon.

Further, only the map data of a district which is often used by the holder is stored in the portable remote terminal. In this regard, when the holder is in a district not contained within the retained map data, he/she downloads corresponding map data from the central system and uses the downloaded map data.

Title: Viscous operated friction coupling with universal joint
Inventor: MAYR NIKOLAUS
IPC: F16D3/223
Filed: 1997-10-10
Abstract: A coupling assembly, for a motor vehicle, comprises a friction coupling 17 having a hub 19 which forms an outer joint part of a constant velocity universal joint 20. The friction coupling 17 is operated by a pump unit 28 comprising a pressure chamber 67 having a piston 29 which moves so as to engage the friction coupling 17 when a viscous fluid is pressurized.

Title: Calibrating a scanning heterodyne or scanning filter based optical spectrometer
Inventor: WOOD NIGEL ROBERT
IPC: G01J3/06
Filed: 1998-01-16
Abstract: The scan range of a scanning heterodyne or scanning filter based optical spectrometer, suitable for localised and distributed Wave Division Multiplexer and high density WDM use, is calibrated using a fixed Fabry-Perot etalon to produce equispaced reference transmission maxima from the output of a tunable LO laser. These maxima are used to detect errors in the wavelength positions of the signals received on the various channels from the transmitters and to send correction signals to the transmitters. A passive optical network combines the transmitter signals to produce a transmitter comb and a stabilised optical reference signal outside the range of the comb is added to the comb. The non-linearity of the scanning LO laser is determined from the delay between detection of the optical reference signal and the first transmission maximum from the etalon and this delay is applied as an offset to the time of detection of the remaining channels.

Title: Drive mechanism
Inventor: BANSEVICIUS RAMUTIS
IPC: H02N2/16
Filed: 1997-08-13
Abstract: The application describes a drive mechanism for elongate prismatic objects (140). The mechanism uses piezoelectric drives (148) and achieves very high accuracy of positioning with minimal backlash, etc., whilst occupying only a small volume. This makes it suitable for use in electro-discharge machining and electro-discharge texturing operations where one or more wire electrodes (140) need to be positioned accurately with respect to a workpiece and maintained in that relative position as the workpiece erodes and the electrode (140) is consumed.

Title: Paying for cellular communications service when roaming
Inventor: O'CONNOR ERICK
IPC: G06Q20/00
Filed: 1999-03-01
Abstract: Method and apparatus where, during roaming, a user 110 requests service from a local cellular communications network 160 and where, in response to communication between the user 110 and the network 160, it is determined that payment will be made by debiting an electronic currency credit. Service is then provided and payment is made by debiting the electronic currency credit. In the described embodiments, the user 110 requests the electronic currency credit from a financial resource 150 using a cellular communications radio link 130 and the electronic currency credit is transferred to the user 110 over the cellular link 130. The request for the electronic credit may be made before requesting service, for example, in the home network 120 prior to roaming, or after requesting service and determining that payment will be by debiting an electronic credit, for example, when in the local network 160 (figs. 2a and 2b). The determination may be by reference to a user's payment profile (figs. 3 and 4) giving various payment preferences, eg. roaming agreement, electronic currency credit. The invention benefits from the electronic currency credit being in the form of universally accepted electronic "cash" not merely pre-paid tokens or network/company specific credit and means enabling foreign currency exchange of the electronic credit may be provided. Thus a local network 160 may provide service to a user and be paid, without requiring a reciprocal roaming agreement with the user's home network 120.

Title: Shower door seal
Inventor: NIXON ROSS OLIVER
IPC: A47K3/36
Filed: 1999-06-24
Abstract: A shower enclosure includes an outward-opening door 3 pivotally mounted in a door opening such that when the door is closed the bottom of the door is positioned above a threshold 21. A pair of magnetic strips 24 and 25 are moulded into the threshold, the innermost strip 24 having magnetic south poles adjacent to the door 3 and the outermost strip 25 having north poles adjacent to the door. The bottom of the door has an H-section moulding 6 which receives a T-section magnetic strip 7 retained by inturned flanges 36 and 37 to permit vertical movement. The strip 7 has magnetic north poles adjacent to the threshold 21 so that when the door is fully closed the inner magnetic strip 24 sealably holds the strip 7 against the threshold. When the door is opened the magnetic repulsion of the outer strip 25 causes strip 7 to lift as it passes over the threshold. The strip 7 may be frictionally held in the raised position to prevent further contact with the threshold until the door is closed again.
