Abstract: A method for assembling a gas turbine engine includes coupling a transition piece between a combustor liner and a nozzle assembly. The method also includes extending a first portion of a flow sleeve from the transition piece about at least a portion of the combustor liner. The method further includes coupling a second portion of the flow sleeve to the first portion of the flow sleeve such that the flow sleeve second portion extends from the flow sleeve first portion and at least partially about at least a portion of the transition piece. The flow sleeve second portion includes a scoop that cooperates with the transition piece to at least partially define a unitary cooling air passage that includes a unitary scoop-shaped opening. The scoop is oriented to introduce a substantially uniform cooling air flow to the transition piece.

Abstract: A method for managing prepaid accounts. A prepaid account is established for an account holder who deposits funds into the account. A virtual account number is issued for the prepaid account. The virtual account number is compatible with a standardized credit transaction system. Use of the virtual account number is limited to transactions placed over the Internet and to transactions between the prepaid account and another prepaid account. A physical credit card for the prepaid account may also be issued to the account holder. Such a credit card has a card account number which is different than the virtual account number. The card account number is also compatible with the standardized credit transaction system. The card account number may also include use limitations.
