    Abstract: This disclosure relates to a disc cutter comprising PCD cutting elements mounted about a circular body via intermediate tool holders. The cutting elements and corresponding tool holders are arranged in sets of typically 4, 5 or 6 tool holders. The sets repeat along the 5 circumference of the body. A tool holder stabilising system is implemented to reduce the occurrence of vibrations, caused by the cutting operation in use, reaching the cutting elements and causing premature failure.

    Abstract: This disclosure relates to a disc cutter comprising a cutter body, a plurality of tool holders and a plurality of cutting elements. The tool holders and cutting elements are arranged in at least one set about the cutter body. Each set comprises tool holders and cutting elements in a predetermined sequence of configurations. In the pre-determined sequence of configurations, the quantity of cutting elements and/or the lateral spacing of the cutting elements varies.

    Abstract: A method for forming a magnesium diboride construction includes providing a mass of grains of magnesium diboride, placing the grains into a canister to form a pre-sinter assembly and sealing the canister. The pre-sinter assembly is then treated at an ultra-high pressure of around 3GPa or greater and a temperature of between around 800C to around 1500C to sinter the magnesium diboride to form a polycrystalline construction. The construction has at least around 95 weight% magnesium diboride and a superconducting transition temperature T c of greater than around 36K, and a critical flux density of greater than around 6x10 8 A/m 2 as measured at 27K.

    IPC: E21B10/567

    Abstract: A cutter element for an earth-boring tool, comprising a polycrystalline diamond (PCD) volume joined at an interface boundary to a cemented carbide substrate. The PCD volume includes a rake face opposite the interface boundary, an edge of the rake face being suitable as a cutting edge of the cutter element. The PCD volume comprises a plurality of strata directly joined to each other at inter-strata boundaries, in which each of a first plurality of the strata comprises PCD material having a first diamond content; each of a second plurality of the strata comprises PCD material having a second diamond content; the second diamond content being greater than the first diamond content; and the strata of the first and second pluralities disposed in an alternating arrangement with respect to each other. The strata are configured and arranged such that a radial line through the edge and a centroid of the interface boundary intersects, within 1,000 microns from the edge, each of the inter-strata boundaries, and the respective tangent plane to each inter-strata boundary at the respective intersection is disposed relative to the radial line at no less than a minimum angle of 30°.
