    摘要： A gas turbine engine augmentor includes an augmentor outer casing 502 and an annular augmentor liner 504 disposed radially within and radially separated from the augmentor outer casing 502 to form a generally annular augmentor liner cooling flow path 500 between the augmentor casing and the annular augmentor liner, and an augmentor flow splitter duct 506 disposed at the upstream end of the augmentor liner and radially between the augmentor outer casing 502 and the annular augmentor liner 504 and defining a splitter flow path 520 between the annular augmentor liner 504 and the annular augmentor flow splitter duct 506. A method of operating a gas turbofan engine including an augmentor includes directing a portion of fan bypass air into a generally annular augmentor liner cooling flow path 500 between an augmentor outer casing 502 and an annular augmentor liner 504, directing a portion of the air in the augmentor liner cooling flow path 500 into a splitter flow path 520 disposed radially outside the augmentor liner 504 and maintaining positive backflow pressure margin between air flow within the splitter flow path and the augmentor liner cooling flow path 500.

    摘要： The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention provides an implied multiplication having differing hierarchical ranks when one of a member of a predetermined prefix set entry is followed by one of two differing suffix set entries. Each of these implied multiplications have a differing hierarchical rank than that of explicit multiplication.

    摘要： Flexible power converter and simplified process controller capable of being configured for a variety of applications with minimal effort. The power converter has a plurality of filtered half-bridges that can be configured for multiple topologies. The process controller can be adjusted through a timing parameter to process the configured feedback signal. External settings or serial port configuration enable stand-alone or processor-based operation. The invention may be quickly and easily applied as a versatile power supply, motor driver, thermal regulator, or controller for Lighting and flow applications. The flexible power converter and simplified process controller reduces development time and cost, reduces parts count and cost, and improves performance and reliability of power and control systems.
