A carbon film may be deposited upon a substrate by an enhanced CVD process in accordance with which nitrogen or a gaseous nitrogen compound such as ammonia (NH3) is added to a gaseous carbon compound such as a hydrocarbon gas in the CVD reaction gas, the added nitrogen serving to inhibit the growth of lattice defects in the deposited carbon whereby carbon may be deposited in a crystalline diamond ...

The invention relates to a method of testing a well, comprising the steps of: - providing a pipe string with a tester valve assembly adapted to allow or prevent fluid flow from an isolated lower interval of the well into the pipe string, said tester valve assembly comprising a valve element movable between a closing and an opening position, said valve element being in a predetermined initial posit...

A system for issuing a family of instructions during a single clock includes a decoder for decoding the family of instructions and logic, responsive to the decode result, for determining whether resource conflicts would occur if the family were issued during one clock. If no resource conflicts occur, an execution unit executes the family regardless of whether dependencies among the instructions in...

The invention relates to compositions comprising acyl derivatives of 2'-deoxyribonucleosides. The invention also relates to methods of treating or preventing radiation, mutagen and sunlight-induced biological damage, and methods for improving wound healing and tissue repair, comprising administering the composition of the present invention to an animal.

A modified phosphoramidite process for the synthesis of nucleotide sequences. By use of a modified nucleoside phosphoramidite it is possible to produce nucleotide sequences which have a modified phosphate residue.

The present invention relates to the coproduction of a combustible gas stream usable as an energy source, a sulfur-dioxide-containing second gas stream usable as a source of oxidant in the gasification of coal, and a sulfur-dioxide-containing third gas stream usable as a feedstock for the production of sulfuric acid. The process includes heating coal in a coal gasification zone in the presence of ...

On a dual-rod cigarette manufacturing machine, the two paper strips for wrapping the two rods are obtained by longitudinally dividing a main strip by means of a cutting device, the strips being fed to the wrapping section along the same route, along which there is provided, for each strip, a tension detecting device. Should the tension of the two strips depart from a preset value, when the tension...

The device is used for protecting telescopic rotating shafts, esp. drive shafts of agricultural implements. It consists of an outer protective plastics tube (5) having a radial projection (10) on its inner surface (14), and an inner protective tube having a radial projection (11) on its outer surface.
