Abstract: A coolant nozzle (20) is used in a machine tool having a rotating bit (22). The nozzle (20) includes a through-aperture (50) for accommodating the bit (22). The nozzle has a coolant inlet (62) and a number of coolant outlets (80) at more than one angular position about the through-aperture (50). Internal surface portions define one or more passageways (74) between the inlet (62) and the outlets (50).

Abstract: GAS TURBINE NOISE SUPPRESSOR Noise generated in a coannular airstream where there are concentric spaced pipes discharging the flow and the outer pipe extends beyond the inner pipe as in the tail pipe configuration of a fan-jet engine is dissipated by discreetly locating tabs extending internally at the discharge end of the inner pipe. This serves to destroy the coherence of the unsteady pressure field occasioned when the coannular flow streams comingle. EH-6593

Abstract: A coolant nozzle (42) is used on a machine tool having a rotating bit (22) of convoluted longitudinal profile for cutting a number of slots (30) in a disk (34). The nozzle (42) includes at least one coolant inlet (82,84) and at least one coolant outlet (78,79). The coolant outlet (78,79) has a convoluted section and is positioned to direct a coolant stream tangentially at the bit (22) in a direction of rotation of the bit. Internal surface portions of the nozzle define one or more passageways between the inlet (82,84) and the outlet(s) (78,79).

Abstract: A quill (10) to be used to superabrasively machine complex shapes, such as airfoil shapes, into a substrate has a shaft portion (12), an enlarged head portion (14) adjacent the shaft portion (12), and a tapered grinding portion (16) adjacent the enlarged head portion (14). The tapered grinding portion (16) has a layer of grit material (24) selected from the group consisting of diamonds and cubic boron nitride thereon. In a preferred embodiment, the quill (10) is a vitrified or plated cubic boron nitride quill on the grinding portion (16). A method of using the tool is also disclosed.
