Title: Soluble plug usable downhole
Inventor: JAMES DAN VICK JR
IPC: E21B33/12
Filed: 2016-08-10
Abstract: A soluble plug assembly 512 includes a housing e.g. in two parts 502, 504 containing a plug 506 retained by a shear pin 508. The housing can be positioned in a wellbore flow path for preventing fluid flow between first 512a and a second 512b parts of the flow path. The plug can include a solid material e.g. metal, plastics, rubber or combinations thereof for at least partially dissolving in response to contact with a fluid, e.g. water or acid, which may be a well fluid or pumped downhole to dissolve the plug to allow fluid flow between the first part and the second part. The pin couples the plug to the housing and responds to a threshold amount of pressure against the plug by shearing to allow the plug to move from a first position to a second position. In the first position the plug may be protected by a coating or a divider 514a, 514b and barrier fluid 516. Once in the second position the plug material may be exposed to fluid and dissolve. The bore covered by the plug may be a radial bore connecting to an annulus.

Title: Remote-open barrier valve
Inventor: PETER D W INGLIS
IPC: G08C17/02
Filed: 2018-12-31
Abstract: An actuation system for remotely transitioning a downhole wellbore tool between distinct operational configurations includes a sensor that can detect a downhole pressure in a tubular string extending into a wellbore and an electronic decoder that monitors the pressure the tubular string until a target pressure profile is detected. When the target pressure profile is detected, the decoder issues a command to an actuation mechanism, causing the downhole wellbore tool to transition between the distinct operational configurations. The target pressure profile may be transmitted from the surface location by operating a pump to produce specific downhole pressure levels for specific time intervals. The specific downhole pressures do not need to be applied directly to the downhole wellbore tool, and thus the each of a plurality of various downhole wellbore tools may be operated independently without interfering with one another.

Title: Apparatus and method
Inventor: Chris Powell
IPC: F24H1/18
Filed: 2020-04-23
Abstract: An air feed device, for a hot water installation comprising an unvented hot water tank, comprises a Venturi tube 410 having a throat section 412 disposed between an upstream section 411 and a downstream section 413. The Venturi tube receives a flow of water passing sequentially through the upstream section, the throat section and the downstream section. A deformable member 430, such as a silicone gasket, is disposed in the throat section and deforms when a flowrate value of the water is above a selected threshold deformation flowrate value. The deformable member deforms by a magnitude based on the flowrate value. A first air inlet aperture 421 is disposed in the Venturi tube at a downstream side of the deformable member, and draws air from an air source into the water via the first air inlet aperture due to the pressure of water at a region at the first air inlet aperture. A flow cross-sectional area of the throat section may be based on the deformation magnitude of the deformable member. The deformable member may deform towards the downstream section and may be disposed between the upstream section and the first air inlet aperture.

Title: Generating Digital signatures
Inventor: Michaella Pettit
IPC: H04L9/32
Filed: 2021-08-09
Abstract: In known signature generation schemes members of a group are given shares of a private key from which shares of a signature are generated. Where at least a minimum threshold number of group participants submit signature shares, which may be less than all the shares, the shares can be combined into a valid signature. The invention is concerned with such a scheme wherein participants submitting signature shares can later prove that they have done so. In the invention ephemeral private keys are created for each viable sub-group comprising threshold or more members, and shares provided to members. A sub-group’s members generate signature shares using the whole group private key share and sub-group ephemeral key share. A coordinator generates a signature from the signature shares and a public key corresponding to the ephemeral sub-group private key.
