Title: Streamers without tailbuoys
Inventor: POULTON DAVID ANTHONY
IPC: G01V3/17
Filed: 2014-02-24
Abstract: A system for indicating the tail ends of streamers, towed by a boat 10, wherein at least one streamer 20A-D is not coupled to a tail buoy. A chase vessel 50 may be proximate to the ends of the streamers and the streamer ends may provide a reference point for the chase vessel. The streamers distal end may comprise a positioning device 26A-D, which may be transmitters configured to send the shape of the array. The chase vessel may communicate 60 the received positions to a global control network. Preferably none of the streamers comprise tail buoys. Positioning devices on the streamer may be controlled to detangle an end portion of a streamer.

Title: Multi-position mechanical spear for multiple tension cuts with releasable locking feature
Inventor: CROW STEPHEN L
IPC: E21B23/01
Filed: 2012-07-17
Abstract: A cut-and-pull spear is configured to obtain multiple grips in a tubular to be cut in tension. A lock feature holds the set position of the slips and seal. The lock can be defeated with an axial force that retracts a spring- loaded dog, and the lock can be reset to the run-in position, with the slips and seal retracted, so that the assembly can be repositioned in the same trip for another cut. A cam surface prevents setting the slips and seal until the spear is relocated to the next desired cut location or removed from the wellbore. The lock can be defeated with picking up or with a pressuring up on a dropped ball for an emergency release. A surface signal of the release is provided by a stack of disc springs that have to be compressed to release the lock.

Title: Method and apparatus for pressure-actuated tool connection and disconnection
Inventor: HALES JOHN H
IPC: E21B17/06
Filed: 2012-04-02
Abstract: A method is presented for connecting and disconnecting sections of a work string for use in a subterranean wellbore. A preferred method of disconnecting includes the steps of positioning a stinger and a downhole tool assembly of a work string adjacent upper and lower sealing rams, such as in a BOP and lubricator assembly. The sealing rams are closed, defining a first and second pressure zone adjacent the tool. A differential pressure is applied across the pressure zones, moving a piston element in the tool assembly. Axial movement of the piston element causes relative rotational movement of cooperating locking elements. In one embodiment, the locking elements are rotated to an unlocked position and then move relative to one another axially in response to a biasing spring. The relative axial movement of the locking elements results in unlatching of a latching assembly, thereby disconnecting the tool and stinger.

Title: Portal imaging during radiotherapy
Inventor: ALLEN JOHN
IPC: A61N5/10
Filed: 2014-09-11
Abstract: A radiotherapy apparatus has a source 110 mounted on a rotatable gantry 104 such as a drum, a portal imaging device (such as an EPID 118) also mounted to the gantry and moveable relative to the source, and a control unit (132, figure 8) arranged to coordinate the movement of both to keep the imaging device in the beam as the source moves to different treatment positions. The apparatus is especially for the treatment of targets lying away from the isocentre of the apparatus. Preferably the beam passes through a multi-leaf collimator (MLC) 116. The EPID may be connected to a gantry arm 120 by a series of servo-controlled linkages 122 arranged transverse to the beam direction to provide movement of the EPID in the transverse plane. Adjustment towards or away from the source may also be provided. Movement of the EPID may be predictive or it may react to the collimated beam approaching the periphery of the imaging area. The movement ensures that the image is valid for dosimetry purposes and prevents damage to the EPID as a result of exposure of more sensitive (or less shielded) parts to the beam.

Abstract: A system 200 may provide for purchases using conventional payment cards 102 such as an Europay/Mastercard/Visa (EMV) credit or debit card or a merchant-specific purchase card 104 through a POS payment terminal 106. The card payment module 106a comprises a tokenisation module 212 operative to generate a token 206 from payment card data, complying with a security requirement for payment cards; and a registration module 220. The token is transmitted for storage in a token store 112, external to the tokenisation module, where a purchase scheme data processing application 114 checks a database to determine whether the token 206 is already registered, i.e. the cardholder is known to the system. If the customer 120 is registered then the details of the transaction 119 are transmitted to their online account 116. If the token is not recognized, then the payment terminal offers the customer the opportunity to register themselves via the registration module 220. In this way, the cardholder may be registered into a scheme such a merchant loyalty scheme that may store details of transactions and / or offer frequent usage benefits and discounts.

Abstract: A control system for performing staging control of a multi-stage combustor (15, figure 2) of a gas turbine engine (10). Fuel is fed to the combustor by a fuel supply system comprising: a fuel metering valve 34 having a position adjustable to control fuel flow rate to the combustor, a pressure drop control arrangement 36 regulating fuel pressure drop across the fuel metering valve, and a staging unit 44 which splits the fuel flow from the valve between the combustor stages. The control system includes a fuel pressure sensor 50 which senses the fuel pressure drop across the valve. The control system further includes a controller 52 which implements a control loop comparing a measurement signal indicating the position of the valve with a demanded fuel flow rate and issues a first command signal which adjusts the position of the fuel metering valve to achieve the demanded fuel flow rate.

Title: Correction of sea surface state
Inventor: LECOCQ PAUL
IPC: G01V1/38
Filed: 2015-02-12
Abstract: A wavefield based on the actuation of at least one source in a body of water used in a seismic survey, also using a plurality of receivers, and a sea surface state at the source at one of a plurality of shot points is determined. The up-going and down-going wavefields may be mathematically separated, and the source-side effects in the up-going wave may be determined. Constant receiver and constant channel ensembles may be cross-correlated, and based on this data may be statistically filtered and a surface consistent time correction extracted to apply to the plurality of shot points. The sea surface state may be determined by comparing an up-going portion of the measured wavefield to an up-going portion of a different measured wavefield. A computing system calculates cross-correlations at a constant channel between consecutive shot points, at a constant channel within a shot point between consecutive channels, and within a constant receiver between consecutive shot points, and corrects the sea surface state. The ensemble of source units, channels and receivers may include a constant distance from the source to a sea surface, and constant channel and receiver directions.
