Abstract: A link for a chain drive is provided comprising an elongate figure eight shaped body having a pair of axially aligned oblong axle apertures. The link is connected by axles at each end to other links having an elongate figure shaped bodies but having axially aligned round apertures. In the alternative each link may have one round aperture and one oblong aperture and the chain is connected such that the oblong apertures are aligned and connected to round apertures.

Abstract: Abrasive tools suitable for precision grinding of hard brittle materials, such as ceramics and composites comprising ceramics, at peripheral wheel speeds up to 160 meters/second are provided. The abrasive tools comprise a wheel core attached to an abrasive rim of dense, metal bonded superabrasive segments by means of a thermally stable bond.

Abstract: A method for precision cylindrical grinding of hard brittle materials, such as ceramics or glass and composites comprising ceramics or glass, provides material removal rates as high as 19-380 cm.sup.3 /min/cm. The abrasive tools used in the method comprise a strong, light weight wheel core bonded to a continuous rim of abrasive segments containing superabrasive grain in a dense metal bond matrix.

Abstract: The disclosure is directed to a bonding tool for use primarily in thermo-compression bonding of electronic circuit components and to a method of making the bonding tool. In one form of the disclosure, a holder is provided and has a substrate mounted at an end thereof. The holder is adapted to receive a heating element. A polycrystalline diamond film is disposed on the substrate, the film preferably being deposited by chemical vapor deposition. In a disclosed embodiment the substrate is a material selected from the group consisting of polycrystalline diamond, cemented tungsten carbide, silicon carbide, cubic boron nitride, and tungsten. In a further form of the disclosure, a ceramic substrate is provided which has a favorable thermal conductivity property as well as substantial electrical conductivity sufficient to permit shaping by electrical discharge machining ("EDM").

Abstract: Finely divided silicon carbide materials, particularly powders, whiskers and short fibers, are provided with a titanium nitride surface coating by the process of (i) placing a low carbon diffusivity layer atop the silicon carbon, (ii) placing a titanium metal coating atop the low carbon diffusivity layer, and (iii) nitriding the titanium metal.

Abstract: A superhard form of boron suboxide (B.sub.x O) comprises at least about 95% by weight of polycrystalline B.sub.6 O and has a KHN.sub.100 value of at least about 3800 kg/mm.sup.2. A method for forming the superhard boron suboxide comprises mixing stoichiometric amounts of boron oxide (B.sub.2 O.sub.3) powder and boron powder and subjecting the mixture to a temperature of about 1800.degree. C. to about 2200.degree. C. and a pressure of about 2,000 to about 6,000 psi while encapsulated by boron nitride. The boron powder comprises about 90 to 95% by weight of elemental boron (B), and at least about 1% by weight of a sintering aid, such as Mg.
