  • Patent number: 6106767
    Abstract: Nickel-base alloys with improved elevated temperature creep and stress rupture lives are disclosed which are particularly useful for components in gas turbine engines exposed to high temperatures and stresses for long periods of time. The alloys are nickel-based consisting essentially of 0.005 to 0.15% C, 0.10 to 11% Mo, 0.10 to 4.25% W, from 12 to 31% Cr, 0.25 to 21% Co, up to 5% Fe, 0.10 to 3.75% Nb, 0.10 to 1.25% Ta, 0.01 to 0.10% Zr, 0.10 to 0.50% Mn, 0.10 to 1% V, l.8-4.75% Ti, 0.5 to 5.25% Al, less than 0.003% P, and 0.004 to 0.025% B. Key to the improvement of creep and stress rupture lives is the extremely low P content in conjunction with high B contents.

  • Patent number: 6032627
    Abstract: A valve actuation device. The device may include a free floating valve bridge movably supported within a cavity in the engine housing. The bridge may be provided with a cavity and an orifice arrangement for pumping gases entrained with lubricating fluid toward the piston stems as the bridge reciprocates back and forth. The device may also include a rocker arm that has a U-shaped cross-sectional shape for receiving at least a portion of the valve bridge, valve stem valve spring and spring retainer therein. The rocker arm may be provided with lubrication passages for directing lubrication to the point wherein it is pivotally affixed to the engine housing.

  • Patent number: 6019879
    Abstract: The present invention is directed to an electrochemical gas sensor network. The network includes a gas sensor for receiving a gas and for generating a target gas concentration signal. The gas sensor has an output terminal for providing an output signal that is a product of the target gas concentration signal and a first transfer function. The network also includes a compensation circuit having an input terminal connected to the output terminal of the gas sensor. The compensation circuit also has an output terminal which provides an output signal that is a product of the output signal from the gas sensor and a second transfer function. The second transfer function is approximately an inverse of the first transfer function. The present invention also contemplates a method of compensating for the attenuation of a high frequency component of an output signal of a gas sensor.
