Abstract: A topical patch device is disclosed, which is designed for the relief and control of psoriasis through delivering medication directly into the skin. The topical patch device comprises a body component which is a patch that is configured in a variety of shapes. The body component comprises medicinal ingredients designed to treat psoriasis. Further, the body component comprises a protective adhesive backing that can be peeled away once application is needed to expose the medicinal ingredients. Users can then secure the patch to an affected area to obtain a better, more consistent method of absorbing medication when compared to foams and lotions.

Abstract: An Acousto-Optic Gyroscope (AOG) consisting of a photonic integrated device embedded into two inherently matched piezoelectric surface acoustic wave (SAW) resonators sharing the same acoustic cavity is disclosed. The micromachined strain-based AOG uses the effective index of the optical waveguide due to the acousto-optic effect rather than conventional displacement sensing.

Abstract: Methods and tools for cutting a component in a wellbore are include use of a downhole tool that is tripped into a wellbore. The downhole tool includes at least one sensor that determines whether a quality of a cement around casing satisfies a predetermined standard. The casing is cut to remove an axial section of the casing and the at least one sensor determines whether at least a segment of the axial section of the casing remains adhered to the cement after the casing is cut. A casing removal tool can be activated to remove any remaining segments of casing in the axial section. A plug can be formed in the area where the axial segment of the casing was removed. The downhole tool may include a cutting tool with a laser, abrasive jet, or other cutting element shielded from wellbore debris by a fluid stream.

Abstract: The present invention provides a swivel sub for connection in a work string between a workstring and a downhole apparatus. The swivel sub includes a first substantially cylindrical body, including a sleeve portion having one or more teeth and a second substantially cylindrical body being partially located within the sleeve portion. The bodies are arranged to rotate relative to each other. The swivel sub also includes a sliding sleeve, having one or more teeth arranged mutually engage with the first teeth is axially moveable between disengaged and engaged positions, in one embodiment by a pressure differential being created in the sub. Further, the present invention provides methods for of running the tool, with particular application to setting and hanging of liners and screens.

Abstract: A downhole locator apparatus, including a tool body having a central axis defined therethrough, and at least one locator lug radially expandable from the tool body, in which the at least one locator lug is configured to be received in an annular groove formed in an inner surface of a casing string, in which the at least one locator lug is configured to move radially between a retracted position and an expanded position.

Abstract: A tubing shoe (10) for use on work strings in well bores as are typically utilised in oil and gas production. The shoe comprises a cylindrical body (12) upon which is arranged a reaming portion (22) including pairs of teardrop shaped raised reaming members (26), each pair being mounted oppositely, in parallel and longitudinally along the body. Adjacent pairs of members provide a funnel (42) for collecting approaching debris and a channel for grinding the debris. A nose (14) may be mounted on the end of the shoe, the nose being eccentric or including cutting blades to assist the shoe in breaking through shale and clay stone bridges. A non-aggressive stabiliser (54) in the form of helically arranged blades may also be located on shoe.

Abstract: An apparatus for producing an optical spot on the order of 25 nm in a recording media. The apparatus includes an optical transducer comprising a waveguide which defines an aperture adjacent to an air bearing surface of the transducer adjacent a recording media. The transducer includes a protrusion extending beyond the plane of the air bearing surface extending toward the recording media.

Abstract: A tool for reducing torque on work string, eg for gas or oil production, comprises an upper clamp (2), a lower clamp (3) and connection means (4), the three components formed as a unitary structure (1). The tool also comprises bearing means, preferably made from an elastomeric compound, and an annular body (7) (see FIG. 4) held in place over the connection means by the clamps. The clamps may comprise spigots (5) for retaining the connection means. In a preferred embodiment the annular body is in two semi-annular components connected at one end to allow them to pivot, and the other end comprises mating castellations for receiving a fastening pin. The annular body may comprise a number of replaceable wear pads (14) which may be made of bronze or an elastomer. The unitary structure of the tool enhances the integral strength and efficiency of the clamps.
