Abstract: A fuel dispenser with a booted nozzle for vapor recovery is modified to include check valves in a vapor return path. The check valves selectively allow atmospheric air into the vapor return path to alleviate nuisance shut offs at the nozzle when ORVR vehicle is being fueled. The check valves may be included anywhere in the vapor return path between the nozzle and the vapor recovery vacuum assist pump. The fuel dispenser may further include a pressure sensor in the vapor return line so that the fuel dispenser can determine if the vehicle is an ORVR vehicle or not. If the fuel dispenser determines that an ORVR vehicle is present, the fuel dispenser may modify the operation of the vapor recovery system.

Abstract: A pump housing that contains a pump that draws fuel from an underground storage tank containing fuel to deliver to fuel dispensers in a service station environment. The pump is coupled to a double-walled fuel pipe that carries the fuel from the pump to the fuel dispensers. The double-walled fuel piping contains an inner annular space that carries the fuel and an outer annular space that captures any leaked fuel from the inner annular space. The outer annular space is maintained through the fuel piping from the pump to the fuel dispensers so that the outer annular space can be pressurized by a pump to determine if a leak exists in the outer annular space or so that fuel leaked from the inner annular space can be captured by a leak containment chamber in the pump housing.

Abstract: A shear valve assembly for a fuel dispenser that ensures that the energy from an impact to the fuel dispenser causes a shear valve placed inline to the fuel supply conduit to engage if there is a possibility that such impact could cause the fuel supply conduit to break thereby causing a leak of fuel to the environment. The shear valve assembly may be constructed as part of the fuel dispenser during the manufacture of the fuel dispenser, or the shear valve assembly may be constructed separately from the fuel dispenser and attached to the fuel dispenser in the field during installation of a fuel dispenser.

Abstract: A multistage information purchasing system comprises a vehicle onboard computer configured to arrange for the purchase of information through a wireless communications network. The vendor from whom the information has been purchased indicates a proximate docking station from which the purchased information is available and the vehicle is directed to that docking station. At the docking station, the consumer downloads the purchased information to the onboard computer for later manipulation or use. Alternatively, the consumer may abort the transaction if it is inconvenient to travel to the docking station.

Abstract: A flow switch used in conjunction with a fuel meter in a fuel dispenser to determine when fuel is flowing. A flow switch can only be activated if fuel is flowing through the flow path of the flow switch. If fuel is flowing as indicated by the fuel flow switch, but the meter is not registering fuel flow, there is a meter error, which may be an error internally with components of the meter and/or a pulser that generates pulse signals indicative of fuel flow. If the meter pulser is registering fuel flow, but the flow switch is not registering fuel flow, then an error exists with the flow switch. If fuel is flowing and there are no errors, both the meter and the flow switch should indicate fuel flow.

Abstract: A dispensing system for dispensing volatile liquids such as hydrocarbon fuel for vehicles into a tank having a filler neck also collects the vapors to reduce atmospheric pollution. A fuel delivery hose includes a hand-held fuel valve and nozzle for insertion in the opening of the tank. A means delivers fuel under pressure to the fuel delivery hose, and another means provides electrical pulses corresponding to the volumetric flow of liquid through the fuel delivery hose when the fuel valve is open. A vapor recovery hose includes a vapor intake connected to the hand-held nozzle for insertion in the opening of the tank without sealing with the tank, and a motor driven vapor pump produces a volumetric flow through the vapor recovery hose corresponding to a signal applied to the motor. A processing means produces the signal applied to the motor in response to the electrical pulses to produce a volumetric flow of vapor slightly greater than the volumetric flow of fuel to the tank.

Abstract: A lower cost turbine flow meter comprised of an inner housing constructed out of a high permeable material surrounded by an outer housing constructed out of a lower cost, lower permeable material. A port is placed in the outer housing that runs down to the surface of the inner housing to detect the rotation of turbine rotors that rotate inside the meter as fluid or gas flows through the meter. A pickoff coil is placed in the port to generate a magnetic signal to penetrate through the inner housing wherein the turbine rotor vanes superimpose a pulse signal on the magnetic signal. The lower cost turbine flow meter can be used for any application for measuring fluid or gas, and may be used in a service station environment for measuring fuel or vapor in vapor recovery applications.

Abstract: A turbine flow meter used as a vapor flow meter in a vapor recovery-equipped fuel dispenser. The turbine flow meter measures the vapor recovered by the fuel dispenser during a fueling operation that is returned back to the underground storage tank. The turbine flow meter measurements may be ignored when fuel is no longer flowing through the fuel dispenser since the turbine rotors in the turbine flow meter may continue to rotate even after vapor is no longer being recovered.

Abstract: A dual piston/poppet valve in a fuel dispenser works with a two-stage valve to help eliminate errors from an inferential flow meter. When the two-stage valve opens partially, a secondary fuel path is opened in the dual piston/poppet valve. A sensor detects the opening of the secondary fuel path and reports its opening to a control system. The two-stage valve opens fully and a primary fuel path is opened concurrently. During transaction completion, the two-stage valve partially closes, resulting in the closing of the primary fuel path. When the two-stage valve closes completely, the secondary fuel path closes. The sensor detects the closing of the secondary fuel path and reports the closing to the control system. Based on the outputs of the sensor, the control system accepts or declines input from a flow meter.

Abstract: A dual piston/poppet valve in a fuel dispenser works with a two-stage valve to help eliminate errors from an inferential flow meter. When the two-stage valve opens partially, a secondary fuel path is opened in the dual piston/poppet valve. A sensor detects the opening of the secondary fuel path and reports its opening to a control system. The two-stage valve opens fully and a primary fuel path is opened concurrently. During transaction completion, the two-stage valve partially closes, resulting in the closing of the primary fuel path. When the two-stage valve closes completely, the secondary fuel path closes. The sensor detects the closing of the secondary fuel path and reports the closing to the control system. Based on the outputs of the sensor, the control system accepts or declines input from a flow meter.

Abstract: A vapor pressure equalizer system for reducing the pressure of a storage tank that contains volatile liquid or fuel. A conduit is connected to the storage tank that draws vapors present in the ullage of the storage tank into the conduit. The vapors are circulated through the conduit to cool the vapor and return the vapor to the storage tank. In this manner, the pressure of the storage tank is reduced since the vapors being returned are cooler and smaller in volume than when the vapors entered the conduit. The conduit may be an open system that circulates vapors, or may be a closed system that circulates a cooling media through a radiator in the ullage of the storage tank. An electronic controller controls the operation of the system according to measurements that indicate an overpressure condition or a likelihood of future over-pressurization.
