Title: Training device
Inventor: ANDREW DAVID HOUSTON
IPC: A61B5/11
Filed: 2021-04-19
Abstract: A training device for visualising limb motion includes a sensor 1 for tracking the motion of a user’s limb 15, a processor 2 and a screen 3. The processor 2 processes the sensor data to present an image 10 of the user’s limb, and produces and displays a target limb image (9, fig 2). The target limb image 9 is adjusted by a user 16 or operator (18, fig 3) with adjustment factors to variably display the target image 9. There may be a shroud (7, fig 3) on which the screen 3 is positioned to block the user’s limb 15 from their view. The target limb image 9 may be a wireframe model overlaid with photographic images of the user’s limb. The adjustment factor may be a sum of the motion of the target limb image 9 and a percentage of the motion of the limb image 10, or the sum of the motion of the limb image 10 and a further percentage thereof.

Title: A method of isolating casein from dairy powder and butter suitable for stable isotope ratio analysis (SIRA).
Inventor: RAQUEL CAMA-MONCUNILL
IPC: C07K14/47
Filed: 2022-05-25
Abstract: A method for isolating casein from dairy powder or butter comprises an initial lipid removal step, precipitating the casein from the delipidated product, and removing lipids two more times using subsequently more polar solvents to provide isolated casein with a purity of greater than 93%. The first lipid extraction step may involve centrifugation or solvents, the second may comprise petroleum spirit:diethyl ether, and the third lipid extraction step may involve heptane:isopropenal. The delipidated casein may be freeze dried, and that may be before the third lipid extraction step. The precipitation may be by acidification to pH 4.3-4.6. The isolated casein may have a C/N ratio or 3.2-3.7. There are also claims for the use of isolated casein in stable isotope ratio analysis (SIRA).
Patent GB-2619296-A (GB)
Title: Graphics processors
Inventor: Daniel Fedai Larsen
IPC: G06T15/00
Filed: 2022-05-30
Abstract: A method of processing data in a graphics processor when performing tile-based rendering in which a render output is sub-divided into a plurality of tiles for rendering. The rendering is performed as two separate processing passes. A graphics processor with a geometry processing circuit 620 is configured to perform the first pass 601 and comprises a sorting circuit, a primitive list preparation circuit and a tile elimination data generating circuit. The first processing pass sorts primitives into respective regions of the render output (‘binning’), during which tile elimination data 612 is generated indicative of which of the rendering tiles should be rendered during a second processing pass. The tile elimination data generated in the first processing pass can then be used to control the rendering of tiles during the second processing pass 602. The tile elimination data generating operation may use primitive lists to determine which of the tiles contain primitives and may add end command pointers to the lists. Alternatively, the tile elimination data generating operation may generate a cumulative bounding box 808, and any tiles that intersect it potentially contains primitives to be rendered. Any tiles that are not determined to potentially contain primitives may still need to be rendered, determined by comparing a tile signature.

Title: System for improving flexibility of riser supports in stationary production units and installation method
Inventor: RAFAEL MOREIRA DE BRITO
IPC: E21B43/01
Filed: 2021-08-16
Abstract: The present invention relates to a system comprising one or more pipes with low flexural rigidity (upper and intermediate extension pipes) that are connected to a pipe section of greater thickness (lower extension pipe) by means of a pipe with a variable cross section (conical profile) and an adapter in the form of a bend stiffening cap for a flexible riser to enable the use of rigid risers in stationary production units (SPU) that were initially designed to receive flexible risers only and that therefore have no specific supports for rigid risers, without compromising operation. The low flexural rigidity of the pipe is achieved by the correct selection of specific materials, preferably using a titanium alloy that has a low Young's modulus and a high yield point compared to steel.
