    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: LOW JET NOISE TURBOFAN SUCKLER Jet noise generation occasioned from the gaseous streams in the coaxial streams of a turbofan engine when they as well as the ambient stream encounter is reduced by designing the engine so that the value of the true velocity of the outer stream is substantially higher than the value of the true velocity of the inner stream. For a turbofan engine that incorporates fan duct burners, the velocity of the fan stream could be initially designed to be always at a higher velocity than the core engine stream.

    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.
