Abstract: A method of reducing noise from a combustor of a gas turbine engine includes the steps of establishing a maximum noise limit that may be for a particular frequency range. A primary fuel flow percentage, which may be emitted from a fuel nozzle arrangement having various groupings of simplex and duplex nozzles, is then established. An immersion depth measured between an aft rim of a swirler and a distal tip of the fuel nozzles may then be reduced thereby reducing the noise amplitude.

Abstract: A convertible back bar is provided. In one embodiment, a convertible back bar comprises a mirror, a body configured to support the mirror, a shelf, and a billiard ball storage tray. The shelf and the billiard ball storage tray are interchangibly attachable to upper and lower ends of the body. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

Abstract: A billiard table with a movable apron that conceals/exposes a storage compartment is provided. In one embodiment, a billiard table is presented comprising a playing surface, a rail positioned along an edge of the playing surface, a storage compartment, and an apron movable between a first position in which the apron conceals the storage compartment and a second position in which the apron exposes the storage compartment. In another embodiment, a billiard table is presented comprising a playing surface, a rail, and a storage compartment that provides a mechanical connection between the playing surface and the rail.

Abstract: A rack for storing billiard balls including a base having a first engagement surface. The rack also includes an elongated billiard ball holder defining an elongated central space configured to support a plurality of billiard balls in contact with one another in a row. The billiard ball holder includes an opening to the elongated central space such that billiard balls can be inserted into the central space through the opening. The billiard ball can be tilted to roll the stored billiard balls through the opening. The billiard ball holder has a second engagement surface configured to removably engage the first engagement surface of the base and retain the billiard ball holder in a generally upright position wherein the elongated central space extends generally vertically. The billiard ball holder is removable from the base to facilitate transport of the billiard ball holder and stored balls to an associated billiards table.
