Title: Downhole signalling using a metallic structure and a magnetic toroid
Inventor: HUDSON STEVEN MARTIN
IPC: E21B47/12
Filed: 2011-06-27
Abstract: System for electrical signalling between first and second downhole locations in a well containing a metallic structure 1. Units 3 / 4 at first and second locations apply signals to and/or receive signals from the metallic structure. A third location between the first and second locations has a magnetic toroid 51 around metallic tubing 1 of the metallic structure. The magnetic toroid has a winding 52 which is connected to a cable 53 which runs along the metallic tubing. The first unit applies a signal to and/or receives a signal from the metallic tubing via the cable and magnetic toroid allowing signalling between the first and second units. The cable may bridge an electrically insulated part of the metallic structure. A further independent claim defines passive relay apparatus comprising first and second magnetic toroids (see FIG 2) with windings and a cable connected between the windings of the toroids.

Title: Adding weight to a sag bend of a pipe during initial stages of pipeline laying
Inventor: ANDRESEN TOMMY
IPC: E21B17/01
Filed: 2011-07-01
Abstract: The invention relates to the initiation of laying of an elongate flexible riser / pipeline 10 on the sea bed 16, wherein a termination head 12 is provided at an end of the pipeline, the termination head connected in turn to an anchor 14, wherein a sag bend curvature 24 is imparted to the pipeline by adding weight 30 locally to the pipeline at a sag bend region, wherein the termination head and portion of adjoining pipeline 26 are oriented towards the horizontal while above the seabed. Ideally, an installation vessel 28 applies tension to the riser / pipeline during the start of the laying process, which coupled with the addition of ballasts, causes the end region of the pipeline to curve towards the horizontal, parallel to the sea floor. The weights may take the form of individual ballast modules 30, or a thickened, possibly denser, region of the pipe end itself. Other independent claims relate to different stages of the initial pipe laying process.

Title: A machine for applying container carriers to containers
Inventor: BATES STEPHEN PAUL
IPC: B65B17/02
Filed: 2011-11-23
Abstract: A container packaging system for containers applies an apertured plastics film carrier stock 110 to substantially identical containers 22 such as beverage cans having annular chimes, cylindrical side walls, and frusto-conical walls between the chimes and the side walls. The carrier stock 110 has shaped apertures to securely retain drinks cans, food cans, bottles and similar containers, as a multi-pack unit. The carrier stock is rolled onto suitably juxtaposed containers engaging a tabbed aperture edge portion progressively from above to below the upper edge of the respective containers to be multi-packed using only elastic deformation of the film and assumes a waveform 3D conformation to unitise the containers. The rolling method contrasts prior stretch application methods and enables cheaper and thinner carrier stock to be used.

A subsequent step (103 figure 1) involves applying the respective determined second read voltage to the memory cell for obtaining a second read current for each of the N memory cells. The second read voltage may be determined such that the second read current is constant for all memory cells programmed with the same level or may have one respective target current for each of the K programmed levels. The target currents may be determined as the level means of the first read currents, as blind estimations or may involve the use of a number of identical reference cells. The method may also include data mapping of read currents to the respective cells. The apparatus for measurement includes a voltage generator 13 for applying a bias to the bit line connected to the resistive memory, a current detector 14 for measuring the current through the resistive memory device 11 and a measurement controller 15 all of which may be computerised.
