    Abstract: A compression sealing apparatus for efficiently repairing leaks in pipes and storage/containment structures. The apparatus includes an externa! compression member, an internal compression member, and a compression mechanism that is operative to draw the compression members towards each other to clamp the wall containing the leak between the compression members. Sealing can be enhanced by injecting sealant material through the apparatus to sea! a cavity formed by the apparatus. The compression seal apparatus can also include an expandable insert plug that is installed in a hole in the wall of the pipe or storage/containment structure.

    Abstract: This invention provides a system and method for printing continuous web and feeding ink to printing pens (or cartridges) that employs an array of interleaved ink-jet pens that are arranged to receive bulk ink through a manifold. The manifold and pens are mounted on a fixed array suspended over the web feed path. The manifold includes a plurality of self-sealing quick-disconnect couplings that each serve a discrete ink-jet pen. The pens lay down ink in a registered manner across the full width of the web. The pens are organized into two parallel, multi-pen arrays that are each diagonally oriented with respect to the feed direction. The feed path allows for duplex printing with a second web-side's array located on a lower level of the device, generally beneath the first-side's array. Duplex printing is facilitated due to its inherent length of the feed path. The printed part of the web is free of contact over predetermined lengths that ensure sufficient time for the drying of ink. Each pen is interconnected with a connection to a respective manifold that maintains a vacuum so as to prevent seepage of ink from the pen nozzles. The vacuum is maintained by a draw pump, while ink is continuously provided to the manifold via a float switch in a pressure regulator. The regulator is fed by a bulk ink supply using a feed pump. A check- valve standpipe on each manifold assists in removing any trapped air from the system, thus assisting in maintaining the vacuum.

    Abstract: A tubular assemblyis disclosed for use in a wellbore of an oil, gas or water well, typically for landing a downhole device in the wellbore. The assembly has a sleeve adapted to receive the body of the downhole device. The sleeve is deployed into a conduit in the wellbore and expanded, so that the outer circumferential surface of the sleeve is radially expanded against the inner surface of the conduit. The sleeve has a bore with an inner circumferential surface comprising an inwardly facing formation adapted to engage with an outwardly facing formation on the body of the downhole device when the body of the downhole device is disposed in the bore of the sleeve. The sleeve is typically deployed in the wellbore at the desired location and is radially expanded by an expander device that is deployed within the bore of the sleeve. The expanded sleeve plastically deforms and retains its expanded configuration after the radial expansion force is removed from the sleeve. The sleeve provides a modular anchoring or landing point in the wellbore that can be retrospectively set in the conduit at different locations, and various downhole devices can then be deployed into the sleeves at predictable depths and a reliable connection can be made with the sleeve. The assembly can typically pass through a smaller diameter before being morphed to seal and anchor in a larger diameter.

    Abstract: A braking system comprising a rotator (3) having a contact surface (4); a stator (5); mounted to the stator (5), a multiplicity of separate elements (60) packed together, the elements (60) collectively being engageable selectively with the contact surface (4) of the rotator (3) for braking rotation of the rotator (3). The multiplicity of separate elements (60) are arranged to allow flow of a fluid therethrough. A pressurised fluid system is arranged to cause fluid to flow through the elements (60) for cooling. The fluid flow cools efficiently because heat is removed close to where it is generated. This allows the braking system to be compact and simple in construction. The flow of fluid may also force the elements (60) into frictional contact with the rotator (3).

    Abstract: A zonal isolation device (10; 20; 30; 300; 400; 500; 600) in the form of an active external casing packer is provided which includes a tubular section such as a casing or liner (1; 21; 31; 171; 203) arranged to be run into and secured within a larger diameter generally cylindrical structure such as an open borehole (163; 213). At least one sleeve member (3; 23; 33; 43; 173) is positioned on the exterior of the casing or liner and is sealed thereto and at least two deformable band members (201; 401, 403; 501) are provided around and are bonded to the outer circumference of the sleeve member. The sleeve member and the at least two deformable band members is/are expanded into place against the inner circumference of the open borehole by increasing the pressure within the sleeve member. The method detailed herein also provides zonal isolation by use of a pair of spaced apart sleeve members during a frac operation where frac fluid is supplied to a zone (in between the pair of sleeve members) requiring to be frac'd, where the frac pressure acts not only on the outside of the zonal isolation device but also on the interior of the sleeve member to enhance the seal provided thereby.
