A method of producing a composite diamond compact comprising a polycrystalline diamond (PCD) compact bonded to a cemented carbide substrate is provided. The method includes the steps of: providing a PCD table, preferably a PCD table with diamond-to-diamond bonding and a porous microstructure in which the pores are empty of second phase material bringing together the PCD table and a cemented carbide substrate in the presence of a bonding agent to form an unbonded assembly; subjecting the unbonded assembly to an initial compaction at a pressure of at least 4.5 GPa and a temperature below the melting point of the bonding agent for a period of at least 150 seconds; and thereafter subjecting the unbonded assembly to a temperature above the melting point of the bonding agent and a pressure of at least 4.5 GPa for a time sufficient for the bonding agent to become molten and bond the PCD table to the substrate to form a composite diamond compact.

A surge-resistant and abrasion resistant flexible insulating enamel has resin in an amount of 12 wt % to 76 wt % per 100 wt % by weight of the enamel, an organic solvent in an amount of 20 wt % to 80 wt % per 100 wt % by weight of the enamel, polyethylene oxide (PEO) intercalated clay in an amount of 0.005 wt % to 16 wt % per 100 wt % by weight of the enamel, and organic dispersible silica nano-particles in an amount of 0.995 wt % to 16 wt % per 100 wt % by weight of the enamel. The clay and silica nano-particles have high dielectric constant to absorb, disperse evenly and evacuate surge, which prevents an insulating layer made by the insulating enamel from being damaged from the surge. PEO provides the insulating layer has good flexibility, adhesion and abrasion resistance.

The invention relates to yarns and fabrics containing nylon staple fiber and high-tenacity man-made cellulosic staple fiber, and garments made therefrom, and has particular reference to fabrics having a high resistance to wear whilst retaining a high comfort level.

A chain is constructed by alternately connecting a pair of outer link plates connected together with pins and a pair of inner link plates connected together with bushings into which adjacent pins of adjacent pairs of outer link plates are inserted. On the outer and inner surfaces of component parts of the chain, a lubricant composition for chains containing 95% to 80% by mass of a lubricant which is liquid at room temperature and 5% to 20% by mass of a wax which is solid at room temperature and having a consistency of from 60 to 475 and a dropping point of from 60° C. to 120° C., is adhered.
