  • Patent number: 6842689
    Abstract: A method and system may be provided to perform a process for controlling power provided by an engine in a machine. In an embodiment of the present invention, a process for controlling power provided by an engine operating in a machine is provided. The process may include determining a first power value reflecting a predetermined first power to be provided by the engine to a component operating in the machine and determining, during machine operations, at least one of a parasitic load power value and an intermittent power load value. A second power value may then be determined that reflects a second power provided by the engine based on the parasitic power value, the intermittent power value, and the net power value. The second power value is adjusted such that the engine substantially provides the predetermined net power to the component.

In an embodiment of the present invention, a process for controlling power provided by an engine operating in a machine is provided. The process may include determining a first power value reflecting a predetermined first power to be provided by the engine to a component operating in the machine. Further, the process may include determining, during machine operations, at least one of a parasitic power value reflecting power received by a parasitic load module from the engine and an intermittent power value reflecting power received by an intermittent load module from the engine. A second power value may then be determined that reflects a second power provided by the engine based on the parasitic power value, the intermittent power value, and the net power value.

  • Patent number: 4398866
    Abstract: A cylinder of a gas turbine engine is formed of a multilayered construction including a radially inner ceramic ring, the inner surface of which is juxtaposed to the tips of a turbine rotor, an intermediate arrangement of two annular ceramic rings that are substantially L-shaped in cross-section and are disposed in mirror image so as to entrap the radially inner ceramic ring, and a radially outer metallic support means which envelopes the intermediate ceramic rings for maintaining the composite ceramic structure during different operating modes of the turbine engine. The composite ceramic portion of the cylinder enables the engine to operate at higher temperatures, and offers the potential for improved turbine tip clearance control, since the ceramic material is less sensitive to thermal distortion.

  • Patent number: 3983034
    Abstract: A skimmer for removal of liquid and debris, such as skimming oil spills from water, comprising three pontoons, one located in each of the corners of a triangle made up of interconnecting structural members floating on a body of water. The corner pontoons are adjustably buoyant permitting the skimmer to move vertically up or down as a unit in the water so as to adapt to the wave height of the body of water. At the base of the triangle is the skimmer mouth sloping upward towards a sump. The two pontoons on each side of the sloped mouth have a clamp easily attachable to an oil boom which guides an oil slick into the skimmer. The function of the mouth is to skim off approximately two inches of the water surface. The sloped mouth terminates at an impregnable deflector centrally located between two screens that serve as a wave quieting assembly as well as a separator of debris floating on the water. The skimmed water is then directed through the debris screens into a quieting area.
