Abstract: A system and method to allow users to purchase software applications for point of sale (POS) terminals from an application server via a network (e.g., the Internet) utilizing the POS terminal itself. One or more menus providing portals to available applications and their respective demonstration applications are provided to users on POS terminals. The demonstration applications may be directly downloaded from the application server onto the POS terminals. In addition, the user is able to purchase the application via the POS terminal either before or after the user has viewed/downloaded the demonstration application. After purchase, the application may be downloaded directly from the application server onto the POS terminal. Further, information associated with the demonstration applications downloaded to each POS terminal may be reported to a manufacturer of each demonstration application.

Abstract: A fuel nozzle for a turbine engine includes an air admission shroud which admits a flow of air from an exterior of the fuel nozzle into an interior of the fuel nozzle at a position along the length of the fuel nozzle. A plurality of air admission apertures in the air admission shroud could be arranged to cause the air being admitted into the interior of the fuel nozzle to swirl around the interior of the fuel nozzle in a rotational fashion. If the fuel nozzle also includes swirler vanes located upstream of the air admission shroud, which also induce air within the fuel nozzle to swirl around the interior of the fuel nozzle in a rotational fashion, then the air admission apertures of the air admission shroud preferably cause the air admitted through the air admission shroud to swirl in a rotational direction which is opposite to the swirl induced by the swirler vanes. This helps to better mix the air and the fuel within the nozzle.

Abstract: A tunable transition piece aft-frame is disclosed for tuning the exit profile of combustion products as such products flow from a transition piece to a combustion product receiving apparatus. The aft-frame includes a generally rectilinear shaped body which has a laterally extending flange. Dilution holes are formed in the flange and are configured to allow dilution air to penetrate into the flow of the combustion products to shape the exit temperature profile of the combustion products.

Abstract: The ‘IP Diagnostics’ software is a new and innovative method of aiding the deployment and troubleshooting of IP enabled POS terminals. Its purpose is to identify where a failure in the IP connection is occurring. The IP Diagnostics application does this by testing major failure points within the IP chain from the POS terminal to the host.

Abstract: A lean premixed, radial inflow, multi-annular staged nozzle for creating three independent combustion zones within a can-annular, dual-fuel gas turbine combustor is provided. The nozzle includes a pilot zone fueled by a gas pilot nozzle and center cartridge; a flame holder zone fueled by an inner main gas fuel; a main flame zone fueled by an outer main gas fuel; a main radial swirler for mixing a portion of incoming air to the nozzle with the inner main gas fuel supply and the outer main gas fuel supply; an endcover; and means for controlling the ratio of an inner main gas fuel supplied and an outer main gas fuel supplied.

Abstract: To meet emissions standards, many gas turbine engines use some form of lean, pre-mixed combustion systems. These systems may lead to combustion oscillations or other instabilities. Jet combustion techniques provide a stable alternative lean, pre-mixed combustion system. The present invention presents a jet combustion system that includes a first cylinder having a first array of orifices. A second cylinder is positioned coaxially with the first cylinder. The second cylinder has a second array of orifices offset from the first array of orifices.

Abstract: A fuel nozzle for a gas turbine engine injects a liquid fuel flow from a liquid fuel passage in the swirler vane. An air flow over the swirler vane atomizes the liquid fuel flow to form a fuel air mixture. The fuel nozzle eliminates the need for a conventional air blast atomizer.
