摘要： A polycrystalline superhard construction comprises a body (20, 51, 52) of polycrystalline diamond material, a working surface (34), a first region (51) substantially free of a solvent/catalysing material, the first region extending a depth (Y) from the working surface into the body along a plane substantially perpendicular to the plane along which the working surface extends, and a second region (52) remote from the working surface that includes solvent/catalysing material in a plurality of interstitial regions. A substrate (30) is attached to the body along an interface (24) with the second region. A chamfer extends between the working surface and a peripheral side surface of the body. The depth of the first region tapers towards the working surface at the intersection of the first region with the peripheral side surface such that the depth (Υ') of the first region at the peripheral side surface is less than the depth of the majority of the first region.

摘要： A sealing system includes a first gland in a cone and a second gland in a shaft region. A first ring is mounted in the first gland, a second ring is mounted in the second gland and a third ring is positioned between the first and second rings. The first and third rings present a pair of metal seal faces. A third ring is mounted to the second ring through a set of mounting pins which permit axial movement of the third ring. A biasing spring is mounting in the second ring and configured to exert an axial force against the third ring so as to keep the metal seal faces in sealing contact. A third gland is formed between the second and third rings, with an o-ring sealing member installed within the third gland and compressed in a sealing relationship between the second and third rings.
