摘要： A tool insert comprises a substrate (40), a layer of ultra-hard abrasive material (52) bonded to the substrate and presenting a primary cutting edge (54) for the tool insert, and a protective layer (56) bonded to the ultra-hard abrasive material so as to protect the primary cutting edge thereof. The protective layer provides a secondary cutting edge (58) for the tool insert, the depth of the protective layer being selected so as to be sufficient to protect the primary cutting edge whilst cutting, milling or drilling a window through a first substance, such as a casing or lining of a borehole or shaft, but to expose the primary cutting edge upon encountering a second substance, such as a rockbed. The invention extends to a method of drilling a horizontal or angled hole in a sub-terranean rock formation using a rotary drill string and bit incorporating a tool insert of the invention.

摘要： A tool insert comprises a substrate (10) having a support surface and a support ring extending laterally from the support surface. The support ring is sized to define a recess (14) within the confines thereof and a shelf about the periphery thereof. A layer (12) of ultra-hard abrasive material is located within the recess and bonded to the substrate and the support ring (16), and presents a primary cutting edge (22) for the tool insert. A protective layer (18) is bonded to the shelf about the support ring so as to protect the primary cutting edge. The protective layer provides a secondary cutting edge (20) for the tool insert, the depth of the protective layer being selected so as to be sufficient to protect the primary cutting edge whilst cutting, milling or drilling through a first substance but to expose the primary cutting edge upon encountering a second substance.

摘要： A mobile wireless communications device may include a housing having an opening therein and an inwardly extending housing ring adjacent the opening, and a switch carried by the housing and being aligned with the opening. The mobile wireless communications device may further include a backing member within the housing adjacent the opening, and an elastomeric switch membrane comprising a body covering the switch, and a flange coupled to the body and compressed between the backing member and the housing ring to define a seal therewith. The flange may include a flange base, and a pair of flange rings extending inwardly from the flange base and defining a valley therebetween aligned with the housing ring. In another embodiment, the flange may include a flange base and a first flange ring on a first surface thereof, and a pair of second flange rings on a second surface of the flange base and defining a valley therebetween aligned with the first flange ring.

摘要： A composite material comprises a plurality of cores of material selected from the group comprising carbides, nitrides, carbonitrides, cemented carbides, cemented nitrides, cemented carbonitrides and mixtures thereof, dispersed in a matrix. The matrix comprises the components for making an ultra-hard material, such as diamond or cBN abrasive particles, and a suitable binder. The ultra-hard material is polycrystalline in nature and is typically PCD or PcBN. The cores are typically provided as individual particles or in the form of granules. The granules may be further coated with a second coating, which may be a similar material to that of the cores or of an ultra-hard material of a different grade to that of the first coating. The composite material typically takes on a honeycomb structure of a hard material and cores within the pores of the honeycomb structure bonded to the honeycomb structure. The pores of the honeycomb structure may be ordered or random. A method of producing the composite material and a method of producing a tool component incorporating such a material are also provided.
