  • Publication number: 20050198965
    Abstract: A fuel nozzle and gas turbine combustor capable of operating on multiple fuels with reduced carbon build-up to the fuel nozzle and adjacent combustor components is disclosed. The fuel nozzle incorporates a reconfigured gas fuel assembly and mixing tube to eliminate known areas of recirculation. Furthermore, the liquid fuel assembly includes reconfigured spray characteristics to further reduce droplet interaction with the mixing tube.

  • Publication number: 20050000225
    Abstract: A wear cover for use on a gas turbine transition duct support bracket is disclosed. The wear cover, which is manufactured from a single piece of sheet metal, does not require complex manufacturing processes or tools, thereby reducing component cost. The wear cover comprises first and second leg portions substantially parallel to each other and each generally perpendicular to a third leg portion. Each of the leg portions serve to protect a surface of a support bracket finger from excessive wear associated with frictional contact with mounting blocks of a transition duct. The wear cover is designed to slip onto a support bracket finger through a first opening and is fixed to the finger by a means such as welding.

  • Publication number: 20040032124
    Abstract: A hose fitting suitable for use with a reinforced hose is provided that includes a longitudinally extending body having a hose end and a coupling end. The body includes an exterior surface and an interior opening. The exterior surface of body defines a gripping surface and a reinforcement trapping surface. Fitting also includes a socket surrounding the body. The socket defines an interior surface, which cooperates with the exterior surface of the body to define a generally cylindrical opening for receiving the hose. The interior surface of the socket is positioned radially outward of the gripping surface and the reinforcement trapping surface. The hose reinforcement is trapped between the interior surface and the reinforcement trapping surface to inhibit movement of the hose reinforcement.

  • Patent number: 5906861
    Abstract: A borophosphosilicate glass is deposited on a substrate (50) by heating the substrate (50), and contacting the substrate with a mixture of the gases tetramethylcyclotetrasiloxane, trimethylborate, trimethylphosphite, and oxygen, without the presence of a carrier gas. The first three of the gases are produced from liquid sources by controlled vaporization and flow. The gases react at the heated substrate (50) to deposit the glass upon the substrate. In a reactor (52) for depositing the glass, the tetramethylcyclotetrasiloxane and trimethylborate are introduced at a gas inlet location (79), and the trimethylphosphite and oxygen are heated and introduced at another gas inlet location (90). The tetramethylcyclotetrasiloxane and trimethylborate mixture flows toward the location where the trimethylphosphite and oxygen are introduced, and whereat the gases are mixed. This gaseous mixture flows past the heated substrate (50) to deposit the glass thereon.

  • Patent number: 5520214
    Abstract: A regulator and fill valve assembly for filling a fluid pressure tank and for regulating the flow of pressurized fluid from the tank includes a regulator portion having a valve body with a piston chamber. A pressure flow passageway extends from an inlet end to a first end of the piston chamber and an outlet port communicates with the piston chamber. A piston is movable in the piston chamber. A first spring at a second opposite end of the piston chamber urges the piston toward the first end of the piston chamber. A handle is provided for manually controlling the force of the first spring acting on the piston. A check valve assembly is located in the passageway and includes a seat, a valve member, a valve guide and a second spring biasing the valve member and guide towards the seat. The valve member is movable in a direction towards a closed position against the seat by fluid pressure in the passageway and the biasing force of the second spring.

  • Patent number: 4948179
    Abstract: The invention pertains to a fitting consisting of a tubular body which may be readily installed over the end of a smooth wall conduit and removed therefrom and may be quickly connected to a standard unisex adapter mounted on the end of a hose line to place the conduit and hose line in fluid communication. The fitting includes a positive lock for attaching the fitting to the conduit and a flexible retainer is employed for safety purposes to resist "blow off".

  • Patent number: 4786029
    Abstract: A coupling for use with pressurized systems permitting coupling of valved coupling parts even though one of the parts may be under high pressure. An axially reciprocal valve which automatically opens upon the coupling halves being connected is guided within a shell within the pressurized coupling half and a sealed relationship between the valve and shell minimizes the area of valve surfaces exposed to the pressurized medium reducing the axial forces imposed upon the valve toward the closed position. A bleed valve communicating with the valve interior permits valve operation with hydraulic systems in the event of seal leakage.
