Title: Wellbore reamer
Inventor: ALEXANDER CRAIG MACKAY
IPC: E21B10/24
Filed: 2018-04-30
Abstract: A wellbore roller-reamer 22 comprises a rotatable mandrel 24 having a mandrel axis 30, and at least one roller 32, 34, 36 mounted around the mandrel 24 and with a laterally offset axis (44, fig 4). The roller 32, 34, 36 circumscribes a narrowed part of the mandrel 24. The roller is rotatably mounted on an eccentric bearing sleeve (fig 10) such that roller-reamer cuts a wider bore 12 than the drill string. A key (100, fig 10) rotationally locks the sleeve to the mandrel. Three rollers may be provided longitudinally positioned and rotationally spaced about the mandrel, each with its own offset axis (fig 4). The bearing sleeve includes low friction bearing elements, integrally formed or inserted in pockets on the sleeve extending axially, circumferentially or spirally. Lubrication can be provided with a spring-urged piston delivering lubricant from an annular chamber defined by a lubricant sleeve (fig 14). A threaded male pin end allows assembly by sliding the rollers and bearing sleeve over the narrowed mandrel and connection to other elements (fig 15).

Title: System and method for using coils in magnetic resonance imaging
Inventor: Chad Tyler Harris
IPC: G01R33/3875
Filed: 2018-05-18
Abstract: A flexible coil, such as a head coil, combines radio frequency (RF) receive coils and B0 shimming coils in an MRI system. Coupling between the combined shimming and RF coil and the gradient coils is measured by driving the gradient system with a test gradient waveform in a pre-scan. If the coupling exceeds a threshold, action is taken to reduce the coupling e.g. by repositioning the head coil or changing the shimming currents in it. For example, a DC current in the flexible coil may be turned off when the gradient is applied. The invention may be used with echo planar imaging (EPI) or perfusion or diffusion weighted imaging. A parametric model of the coupling between the gradient sub-system and the flexible coil assembly may be used to determine the coupling. An indication of excessive coupling may be made to the operator of the MR system if detected.

Title: Methods and apparatus for aquatic ectoparasite reduction
Inventor: IAN ANDREW JAMIESON
IPC: C02F1/72
Filed: 2019-09-11
Abstract: The present invention relates to exposing aquatic ectoparasites to soundwaves in an aqueous solution comprising hydrogen peroxide and varying the sonic frequency with time. This provides methods of injuring or killing an aquatic ectoparasite, treating an aquatic animal enclosure, reducing ectoparasitic infestation of aquatic animals, and/or improving the appearance, meat quality and/or growth rate of aquatic animals. Apparatus for reducing parasites comprises means for directing soundwaves 13 into an aquatic animal enclosure 3 and varying their frequency spectrum with time and, optionally, a sound- and water-permeable shield 15 and/or sound absorbing barrier or bubble curtain. The enclosure pressure may be raised or lowered, e.g. above or below atmospheric pressure at the water surface, the frequency spectrum may be varied according to measured enclosure temperature, and the generated acoustic pressure or frequency may increase with depth, e.g. by locating sound transducers 11 at the enclosure bottom to direct sound upwards. The hydrogen peroxide forms bubbles 12 that collapse under ultrasound to dislodge or destroy ectoparasites on fish, e.g. salmon sea lice (Lepeophtheirus salmonis).

Title: Method, device, and computer program for setting parameters values of a video source device
Inventor: ROMAIN BELLESSORT
IPC: H04N17/00
Filed: 2019-09-18
Abstract: A method for setting a parameter of a first video camera includes determining a first set of image characteristic values (e.g. noise, contrast, luminance, motion blur, encoding artefacts) from an image captured by the first video camera configured with a first set of parameters (e.g. gain, shutter value). A second set of image characteristic values is obtained from an image captured by a different second video camera configured with a second set of parameters. A comparison is made to determine if any of the first and second image characteristic values are equal or below a threshold difference. If any values are equivalent, a parameter setting of the first video camera is changed using the second set of image characteristic values. Reusing calibration data from another camera may reduce calibration time. The method may be used to automatically optimise settings of a video surveillance system (closed circuit television, CCTV).

Title: A method, apparatus and computer program product for selecting a kit of parts for a stairlift rail
Inventor: ROBERT HORTON
IPC: B66B9/08
Filed: 2020-01-16
Abstract: A method of selecting stairlift components as a kit of parts for a stairlift rail includes acquiring measurement information about one or more physical dimensions of a staircase S1202. The measurement device 1000, such as a PC, or a mobile device (4004 fig.4), which may be a laser or camera based device operated by the homeowner or a skilled surveyor, records live or still images and the data may be sent to a remote device such as a server.

This may be displayed to a user on the measurement device or performed internally without user intervention. However, if the error between the model and actual dimensions are greater than a predetermined offset (delta fig.7) then model corrections or repeat measurements may be required.

Title: Vacuum pump exhaust reed valve with pressure bleed
Inventor: JAMES A DODS
IPC: F16K15/16
Filed: 2020-03-09
Abstract: A system including a vacuum pump 400 and an exhaust reed valve 402 coupled to the vacuum pump. The exhaust reed valve includes a reed valve seal (fig.3, 302), and a body 402. The reed valve seal includes a groove (fig.3, 308), and/or the body defines a hole 404 that extends entirely through the body. The sealing surface is operable to contact the body and create a seal, and the groove is operable to create an unsealed space from which pressurized fluid can escape. The hole is sized to permit pressurised fluid to escape through the hole when the pump is not operating, but also small enough to prevent pressurised fluid from escaping at a rate to prevent a vacuum from being generated when the vacuum pump is operating. The hole and groove are configured to provide a partial seal such that the pressure of the vacuum pump equalises faster when the pump shuts down. This can eliminate detrimental effects such as hydraulic locking and large loads on the cam drive.
