    摘要: A system facilitating payment for fuel dispensing includes a fuel dispenser associated with a current-loop-to-ethernet converter for receiving serial data from a fuel dispenser controller and converting said serial data to an ethernet signal and a network appliance coupled the current-loop-to-ethernet converter by an ethernet port. A virtual payment facilitator is connected to the network appliance over a VPN and to a payment authorization entity, also over a VPN. A process performed by the system includes receiving a fueling request at the virtual payment facilitator from the payment authorization entity and converting that request into a command issued to the fuel dispenser to dispense fuel.

    摘要: A downhole tool has a mandrel with packing elements. Collars between the packing elements define ports communicating with gaps between the packing elements and the mandrels. Opposing piston housings on the mandrel can move in opposing directions to compress the packing elements against the collars. Each piston housing defines a space with the mandrel and has a second port communicating with the gap. Pistons disposed in the spaces are temporarily affixed thereto. Hydraulic pressure communicated through the mandrel's bore acts against the pistons. While affixed to the piston housings, the pistons move the piston housings toward the packing elements to compress then. When the packing elements set, continued pressure breaks shear pins affixing the pistons to the piston housings so the pistons move and eventually seal fluid communication between the second ports in the pistons and the gaps.
