  • Publication number: 20040265198
    Abstract: A power generation aftertreatment system includes a duct system, mixing vanes and a straightening vane. The duct system has a first end and a second end spaced from the first end. The duct system also has an elbow located between the first end and the second end. The elbow is configured to change a direction of flow of a fluid contained within the duct system. The mixing vanes are connected to the duct system and are in contact with the fluid contained within the duct system. The straightening vane is connected to the duct system between the elbow and the second end of the duct system. The straightening vane is in contact with the fluid contained within the duct system.

  • Patent number: 4321597
    Abstract: A cursive writing type cathode ray tube (CRT) display system in which the vertical size of the characters are increased by an input command from a keyboard and central processing unit (CPU). The CRT has both electrostatic and magnetic deflection systems with the magnetic deflection producing a raster in which each horizontal scan is electrostatically deflected to write characters on the screen. The characters are formed from stored digital codes selected by commands from the CPU. Digital to analog (D/A) converters produce analog deflection signals to produce a set of multiple strokes to form a character and to produce analog voltages for controlling the brightness of the stroke. Digital commands from the CPU are generated to increase or decrease the magnitudes of the various analog signals from the D/A converters when changing the vertical character size.
