Abstract: Methods, apparatuses, and systems are presented for generating natural language models using a novel system architecture for feature extraction. A method for extracting features for natural language processing comprises: accessing one or more tokens generated from a document to be processed; receiving one or more feature types defined by user; receiving selection of one or more feature types from a plurality of system-defined and user-defined feature types, wherein each feature type comprises one or more rules for generating features; receiving one or more parameters for the selected feature types, wherein the one or more rules for generating features are defined at least in part by the parameters; generating features associated with the document to be processed based on the selected feature types and the received parameters; and outputting the generated features in a format common among all feature types.

Abstract: A dilution air dispensing apparatus for a double dome combustor with dilution air dispensing holes that are staggered on the opposite walls of the centerbody. The wakes on the downstream side of the jets provide avenues of access for the deflected combustion gases to continue their travel across the combustor and into the regions downstream of the opposite domes. The gases then mix with the remaining undeflected gases from the domes and with the spent dilution air before reaching a combustor exit plane.

Abstract: An air dispensing arrangement within a gas turbine engine in which the energy of the pressurized air exiting the compressor is nonuniform. The higher energy pressurized air is dispensed by at least one conduit to the combustor and to other components, the higher energy air providing an improved cooling capability over the lower energy air. Provision is also made to employ the lower energy air for uses such as the dilution of the combustor gases.

Abstract: An apparatus for dissolving a solid in a liquid flowing in a liquid line is disclosed. The apparatus includes a tank for holding the solid to be dissolved, an intake line for bringing liquid from the liquid line into the tank, and a return line for returning the liquid from the tank into the liquid line. In one arrangement, the return line is inserted an adjustable depth into the tank allowing adjustment of the water flow across the solid to be dissolved within the tank. An intake connector terminates the liquid line end of the intake line. The intake connector extends into the liquid line and forms an opening facing upstream in the liquid line. A return connector terminates the liquid line end of the return line. The return connector extends into the fluid line and forms an opening facing downstream in the liquid line. A hand operable valve and a flow meter are connected in-line with the intake line.
