Title: Device by reel for coiled tubing
Inventor: MYKLEBUST JENS
IPC: E21B19/22
Filed: 1999-07-14
Abstract: The invention relates to a device by a reel (1) for coiled tubing, suitable for use by work in a well such as a well for the recovery of oil. The reel for coiled tubing comprises a reel section (2) with coiled tubing, a reel cradle section (3), and means suitable for unwinding or rewinding the coiled tubing from/on the reel section when the coiled tubing is being inserted into or withdrawn from the well.

Title: Locating the source of an unknown signal
Inventor: RIDEOUT ROBERT MARTIN
IPC: G01S5/06
Filed: 2001-03-27
Abstract: A method of locating the source of an unknown interference signal of varying frequency received by receive antennas (16, 18) via relay satellites (12, 14) involves downconversion of received signals to a first intermediate frequency (IF) and band-limiting the downconverted signals. The band-limited signals are constrained to lie within a prearranged acquisition signal bandwidth by adjustment of local oscillator (LO) downconversion frequency to counteract frequency change in the unknown signal. Downconverted signals are offset in time relative to one another using trial values of differential time offset and their correlation is determined for each trial value to provide actual time offset. Compensation is provided for change in correlation phase angle, which results from signals being downconverted experiencing different LO frequencies during the time interval of the trial offset. The method and associated system may be particularly useful in identifying interference sources in satellite communication channels.

Title: Method of determining a drive control voltage for a piezoelectric actuator
Inventor: RUEGER JOHANNES-JORG
IPC: F02M47/00
Filed: 2001-06-29
Abstract: A method of determining a drive control voltage (U<SB>a</SB>) for a piezoelectric actuator (2) of a fuel injection valve comprise the step of indirectly measuring a pressure in a hydraulic coupler (4) in the valve before each injection cycle. The piezoelectric actuator (2) is coupled with the hydraulic coupler (4), so that the pressure in the latter induces a corresponding piezo voltage (U<SB>i</SB>) in the actuator (2). This induced voltage is measured and used for correction of the drive control voltage for the actuator (2). A too-small induced voltage is evaluated as a fault for the recognition of the need for injection cut-out. The injection valve (1) is preferably that in a common rail system of a fuel injection installation of a petrol or diesel engine.

Title: A high throughput assay for detecting anti-microbial compounds
Inventor: JAWORSKI DEBORAH
IPC: C12Q1/02
Filed: 2001-07-04
Abstract: A high-throughput live whole cell assay method involves measuring the effect of one or more test compounds on a characteristic, e.g., growth, of a cell culture in a multi-well vessel at one or more timepoints during the growth of these cells in culture, after the cells are contacted with the compound. This assay format permits the identification of test compounds that have an inhibitory or stimulatory effect, among others, on cell growth at different times during the growth phase of the cells. It has the advantages of using small volumes which make the assay suitable for automation and enables detection of test compounds with the desired effect that are often missed by conventional assays which assess test compound activity at a single timepoint.

Title: Indirect fluid pressure determination in extraction wells
Inventor: WEBSTER DAVID
IPC: E21B47/06
Filed: 2003-04-23
Abstract: The pressure at a location in a fluid system is determined by supplying fluid to the system to increase system pressure and measuring system pressure when fluid flow between the fluid supply and the location is detected. The fluid system may be a sub-sea hydrocarbon extraction well where the pressure at a location on the seabed is measured remotely/indirectly from above sea level. Flow detectors 5 provided on the seabed are filled with hydraulic fluid and the pressure of this fluid is measured at the surface using a pressure gauge 10. The pressure at a node of the well is determined by increasing the fluid pressure until it exceeds that at the node, when fluid will then flow through the flow detector. Upon detection of flow the real pressure at the node is calculated by summing the hydraulic fluid pressure and the static fluid pressure (calculated from depth of well).

Title: Dynamic channel assignment in a TDD communication system
Inventor: LEGG PETER JONATHON
IPC: H04B7/26
Filed: 2004-04-13
Abstract: A dynamic channel assignment scheme for a TDD radio communication system (100) with coexisting dedicated (230; 240) and shared (210; 220) channels has segregated dedicated and shared channel mechanisms. Up to nDL_DCH_MAX / nUL_DCH_MAX dedicated downlink / uplink channel slots are granted, with the remainder of slots for shared channels. These maximum numbers accommodate the needs of conversational and streaming class traffic carried on shared channels. New slots can be claimed for dedicated channels (subject to this maximum) as required, taking the shared channel slot with the smallest timeslot. If the last DCH allocation in a slot is ended, the slot is freed for DSCH / USCH usage. This provides the following advantage(s): uplink algorithm metrics account for intercell interference, the most significant interference source in TDD mode systems, leading to greater capacity; midcall reallocation allows coverage and quality of service to a user to be maintained when a user moves from the centre of the cell to the cell edge; dynamic split between dedicated channel timeslots and shared channel timeslots allows the network to optimise radio resources according to traffic type, leading to an overall higher capacity when the network supports both dedicated channels and shared channels; alignment of the DCH slots across many cells improves the usefulness of measurements for DCA / CAC.

Title: Respirator mask
Inventor: RICHARDSON GRANT STUART
IPC: A62B23/02
Filed: 2001-08-06
Abstract: A respirator comprises an inner, oronasal mask 2 and an outer, face sealing mask 3, the inner and outer masks defining a cavity 4 there between, an ocular mask 50 including sealing means, an air inlet means 27 an air outlet means 8 operable to deliver exhaled air from the inner mask to the atmosphere and pressurised air supply means 25 operable to deliver pressurised air to the cavity, in which the air inlet means comprise air guidance means 5,7,28 operable to deliver, under negative pressure, air from the atmosphere to the inner mask 2 via the ocular mask 50. Therefore if the pump 25 fails demisting is still performed without the need to change the management of air within the respirator. The eyes of the wearer are still protected from any noxious substances that may enter cavity 4 on failure of the seal of the outer mask, which is likely when the pump fails and constant positive pressure is lost in cavity 4.

Abstract: An Automated Teller Machine (ATM) 1 has a card reader 2 into which a credit card can be inserted by a user and a keypad 3 via which a user can enter a Personal Identification Number (PIN) associated with the card. Mounted inside the ATM 1 is an anti-surveillance device. The device has an antenna adapted to pick up radio signals over wide frequency range, e.g. between around 50 MHz and 6 GHz, and a signal processor for determining whether it is likely that the radio signals represent video data transmitted from the vicinity of the ATM 1. Upon such determination, an output unit is adapted to prevent use of the ATM 1 by switching off power to the ATM 1 from a power supply 8; alerting a central controller 6 via a communication network 7; and/or commanding the ATM 1 to stop dispensing cash and to display a warning on its display 4. Video surveillance of the ATM 1 and, more specifically, of entry of PINs via the keypad 3 is prevented. The invention can equally be applied to Chip and PIN units or such like.
