Abstract: A method for controlling a combustion dynamics level within a combustion device includes defining a high dynamics operating state at a first fuel split ratio. The first fuel split ratio is a ratio of an amount of fuel supplied to the combustion device through a first fuel line to a total amount of fuel supplied to the combustion device. A low dynamics operating state is defined at a second fuel split ratio different from the first fuel split ratio. The second fuel split ratio is a second ratio of an amount of fuel supplied to the combustion device through the first fuel line to a total amount of fuel supplied to the combustion device. The combustion dynamics level within the combustion device is controlled by periodically switching between the first fuel split ratio and the second fuel split ratio.

Abstract: A solenoid assembly for a circuit breaker having a clapper with an increased mass is provided. The mass, preferably at least one non-ferrous slug, increases the mass of the clapper so that the solenoid response time is slowed. That is, the added mass creates an inertial delay that slows the solenoid clapper as the clapper moves between the first position and the second position. Preferably, the delay is between 48 ms and 60 ms, and more preferably 50 ms. The clapper having a non-ferrous slug may also be incorporated into existing circuit breakers by, for example, coupling the non-ferrous slug to the preexisting clapper, or replacing the clapper with a clapper assembly having at least one non-ferrous slug thereon.

Abstract: An engine enclosure for enclosing an engine of a work machine. The enclosure includes a first panel hingedly supported from an enclosure top and extending downwardly therefrom to form an enclosure side portion. A first hinge device joins the first panel to the enclosure top for pivotal movement relative thereto, the first panel pivotable from a closed position to an open position for access of engine components. A second panel hingedly supports and forms another portion of the enclosure side, extending upwardly toward the first panel. A lower portion of the first panel is configured to overlie an upper portion of the second panel when the first and second panels are in a closed position for preventing pivotal movement of the second panel when the first panel overlies the second panel. The second panel is pivotable from the closed position to an open position for access of engine components.

Abstract: Multiple servo sensors are laterally displaced over a distance less than the transverse width of timing based servo track laterally extending transitions. The servo sensors are configured to sense the transitions, and servo detection logic detects the relative timings of the laterally extending transitions sensed by the laterally displaced servo sensors as the magnetic tape is moved in the longitudinal direction. Logic is configured to determine from the relative timings of the sensed transitions for at least one known set of laterally extending transitions having differing slants, the lateral position of a servo sensor by employing the relative timing detected from one servo sensor and the relative timing detected from another servo sensor, or determine the longitudinal velocity of the magnetic tape by determining the difference between the relative timing detected from one servo sensor and the relative timing detected from another servo sensor.
