Abstract: An ambient transaction system is described for facilitating various transactions types between a management system and a connected device over a transaction platform. Based on a variety of different triggering conditions, the transaction platform may establish an integrated session among the transaction platform, the management system, and the connected device. The transaction platform includes integrated logic of the management system such that a presentment layer provided to the connected device by the transaction platform via the integrated session includes features of the management system associated with the transaction type. When the transaction is a payment transaction, the features may include a payment feature through which checkout options may be selected for payment via the connected device.

Abstract: An improved prechamber and fuel manifold structure for a gas turbine engine having a premixing-prevaporizing type combustor, the improvement residing in the provision of a prechamber having an internal cylindrical surface swept by swirling pressurized air passing through the prechamber from a plenum to the combustor and in the provision of a fuel manifold having a plurality of individual fuel conduits extending from a remote fuel supply pipe to a corresponding plurality of delivery heads in the prechamber. The delivery heads direct fuel generally tangent to the internal cylindrical surface to form a film for vaporization in the passing air and the length of the fuel conduits and the flow areas of the fuel conduits and the delivery heads are generally equal so that fuel flow in the fuel conduits is balanced and so that when the conduits are opened to atmospheric pressure at termination of combustion, purging of residual fuel to foreclose coking is rapid and complete.
