Abstract: An adjustable caster assembly includes a body having a top surface and a base, and an opening within the base. A wheel is connected to the body, where the wheel is configured to extend beyond the base of the body to engage a supporting surface. A foot is positioned within the opening in the base and configured to move between an expanded position and a contracted position. The foot may be actuated by an actuation shaft that engages a gear. The actuation shaft may be movable between an engaged position and a disengaged position.

Abstract: A fuel nozzle for a turbine engine is configured to deliver a large volume of a fuel which has a relatively low amount of energy per unit volume. The fuel nozzle includes a fuel swirler plate having fuel delivery apertures which are angled with respect to the flat surfaces of the swirler plate. A nozzle cap covers the end of the fuel nozzle to create a swirl chamber at the outlet end. The nozzle cap may include a plurality of air inlet apertures to allow the air to enter the swirl chamber.

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.
