Title: Preparation of N-alkylated morphinans by reduction of an iminium group
Inventor: HEGGELUND AUDUN
IPC: C07D489/08
Filed: 2006-05-25
Abstract: A process for the preparation of a compound of formula (I) or pharmaceutically acceptable salt thereof wherein R is a hydrocarbon group of 2 to 6 carbon atoms, P is H, CH3 or a hydroxyl protecting group and X is O, CH2 or a protected keto group comprises reducing a compound of formula (II). A compound of formula (II) may be prepared by reacting a free amine precursor, i.e. a compound in accordance with formula (I) but having H rather than CH2R on the ring nitrogen, with an aldehyde RCHO and the reduction may be performed without isolation or purification of the compound of formula (II). Preferably R is cyclopropyl, X is O and P is a methyl group and the compound of formula (I) is therefore 3-methylnaltrexone. Suitable reducing agents include sodium triacetoxyborohydride and sodium cyanoborohydride. The reduction may be performed at below ambient temperature, e.g. at 5 to -30 {C and may be performed in dichloromethane or 1,2-dichloroethane. Where P is methyl, the compound of formula (I) may be demethylated, e.g. with BBr3.

Title: Methods and apparatus for expanding a tubular
Inventor: METCALFE PAUL DAVID
IPC: E21B43/10
Filed: 2006-06-30
Abstract: Methods and apparatus for expanding a tubular 110 with the aid of a compressive force are disclosed. A tubular is run into a wellbore 100. While the tubular 110 is in a compressive state, it is expanded into its desired form. The expanded tubular can be used for multiple downhole functions such as completing multilateral junctions in a wellbore, patching apertures in a wellbore and lining a wellbore. The axially compressive force may be applied by fixing the tubular to the surrounding surface either side of the zone to be expanded, or resting the bottom of the tubular on the bottom of the wellbore.

Title: Bursting disc mounting assembly with incorrect installation warning
Inventor: RUTTER BENJAMIN
IPC: F16K17/16
Filed: 2006-08-24
Abstract: A bursting disc assembly for mounting with gaskets between flanges has a forward or reverse orientated bursting disc 3, an outlet side support ring 5 and may have an inlet support ring 6. The rings may be welded to the disc and dimensioned to engage with flange bolts to centre the assembly. To provide a safety warning when the assembly is incorrectly installed in a reversed orientation, the outlet side ring 5 has a passage 7 through it from its radial interior to its radial exterior. The passage may be a full thickness slot, a groove in either side of the ring of sufficient depth and width (typically 0.5 to 4mm) so as not to be blocked by any gaskets associated with installation or a bore. The passage may be straight or may have a baffle in the form of a bend. On incorrect installation the passage provides a leak path from the pressurised side of the disc which may be visible and will show on system pressure testing.

Title: Dynamic optical waveguide sensor
Inventor: JONES RICHARD T
IPC: G01B11/16
Filed: 2006-03-10
Abstract: A light source 500 illuminates long period grating 508 acting as a sensor disposed between two fibre Bragg gratings 504, 506 (each with different Bragg wavelengths) in optical fibre 104. Port circulator 502 directs light from light source 500 to gratings 504, 506, 508 and then to receivers 514, 518. Light reflected from first Bragg grating 504 passes through port circulator 502 and is reflected by filter 510 before passing through port circulator 502 again and being detected by receiver 2. Light reflected by second Bragg grating 506 passes through port circulator 502 and is detected by receiver 1. Light reflected by second Bragg grating 506 suffers an induced loss in long period grating 508. Analyzer 516 compares the ratio of reflected wavelengths from Bragg gratings 504, 506 and determines the strain, pressure or stress applied to long period grating 508.

Title: Electric motor power sensor based on detecting motor vibrations
Inventor: RUSSELL STEPHEN
IPC: G01L3/24
Filed: 2008-09-18
Abstract: A device for measuring the power output and input of an electric induction motor uses a vibration sensor and frequency analysis to measure the motor speed, and calculates the motor slip and output power from the motor speed and motor plate data. An accelerometer may be mounted on the motor casing and used to detect vibrations. The frequency spectrum of the vibrations includes peaks 2, 3 associated with the AC power supply and the motor rotation speed. Input power is derived from output power and efficiency, the efficiency being derived from motor supplier data or from data on similar types and sizes of motor. The vibration sensor also senses vibration due to the motor drive frequency, thus enabling the motor no load speed to be calculated. An embodiment of the invention applies sensors to a group of motors, and the sum of the input powers can be compared with the total input power for the motor group measured by conventional electrical means. The motor parameters can then be adjusted to minimise the difference between the electrical total power, and the sum of the individual motors under a range of load conditions.

Title: Inhibiting reservoir souring using a treated injection water
Inventor: MCELHINEY JOHN E
IPC: C09K8/60
Filed: 2007-03-07
Abstract: A process for inhibiting souring in a hydrocarbon reservoir provides a feed water including a plurality of phosphorous constituents and having an elevated phosphorous concentration. At least some of the phosphorous constituents are removed from the feed water to produce a treated injection water, which has a reduced phosphorous concentration less than the elevated phosphorous concentration. The treated injection water is injected into the reservoir via a first well and the hydrocarbon is produced from the reservoir via a second well. The process inhibits souring in the reservoir insofar as the treated injection water results in a lower level of souring in the reservoir over time than if the feed water had been injected into the reservoir.

Title: Biometric identity verification utilising a trained statistical classifier, e.g. a neural network
Inventor: PUERTO SERGIO GRAU
IPC: G10L17/18
Filed: 2008-11-28
Abstract: A method and apparatus for providing biometric authentication of a user uses a registration process in which a reference data sample representative of a biometric attribute of a reference user is used to train a statistical classifier such as a neural network to achieve a target output. The set of parameters of the statistical classifier, e.g. the weights that achieve this in the neural network, are stored on a user's device as a first data set. For subsequent authentication of a user to be tested at an access point, the first data set is retrieved from the user device and a second data set representative of the biometric attribute of the test user is generated directly from the test user. The first data set is used as a set of parameters in a statistical classifier, e.g. as weights in an artificial neural network, to generate a trained classifier or neural network and the second data set is then used as input to the trained classifier or neural network. The output of the trained classifier or neural network is then used to determine a degree of correlation between the biometric attribute of the reference user and the biometric attribute of the test user to be authenticated.

Title: Apparatus and method for processing video data
Inventor: PERSSON ERIK
IPC: H04N7/26
Filed: 2009-07-16
Abstract: The video processing apparatus comprising first stage video processing circuitry 200 and second stage video processing circuitry 250. The first stage receives input video data 201 and performs one or more processing operations on the data to generate an intermediate representation of the input data. The intermediate representation comprises separate transient or short term 205 and long term 210 data portions. Transient data is only required for processing of a single video frame, whilst the long term data is required for processing of at least two video frames. The first and second data portions are stored in a buffer, from where they are retrieved by the second stage video processing circuitry which generates output video. The transient data is compressed 215 prior to being stored in the buffer, and then decompressed 240 when retrieved. Such an approach allows the first and second stage video processing circuitry to be decoupled, whilst reducing the storage capacity requirements of the buffer. The transient data may be a set of coefficients used in a transform process.
