A point-of-sale fuel dispensing system, a pump assembly and a method of dispensing fuel at a point-of-sale. The system includes a market fuel storage tank, pump assembly, fuel conduit, separation unit, numerous enriched fuel product tanks and a controller. The separation unit may selectively receive at least a portion of market fuel and convert it into an octane-rich fuel component and a cetane-rich fuel component that may be subsequently dispensed to a vehicle being fueled, where a fuel grade selection and retail payment of a fuel containing the octane-rich or cetane-rich fuel components is provided to the vehicle based on user input at the customer interface.

A fuel dispensing system for dispensing fuel into a vehicle comprises a stationary fuel tank adapted to contain a quantity of fuel. At least one fuel dispenser is in fluid communication with the fuel tank via piping. A pump is operative to transfer fuel from the fuel tank to the fuel dispenser. A level detector is located in the fuel tank. A tank monitor is in electronic communication with the level detector, the tank monitor being operative to produce information indicative of the quantity of fuel in the fuel tank. The fuel dispensing system further includes a fuel additive injection assembly comprising an additive reservoir configured to contain a quantity of fuel additive. A controller is in electronic communication with the tank monitor to receive information indicating a delivery of fuel into the fuel tank, the controller having a processor and memory operative to execute instructions determining when an additive quantity should be provided. Additive piping defines a flow path extending between the additive reservoir and a discharge location. A valve is situated along the flow path, the valve being in electronic communication with the controller to open so that the fuel additive will flow along the flow path. A meter is also situated along the flow path and is operative to measure a flow of the fuel additive, the meter being in electronic communication with the controller.

A method of delivering a selected fuel product having a selected octane level to an operator from a fuel dispenser including a blend manifold, a fuel nozzle, and a fuel hose extending therebetween, including the steps of determining a first volume of a first fuel that is retained in the fuel hose upon completion of a first fueling event, determining a first octane level of the first volume of the first fuel, determining a second volume of a second fuel having a second octane level, and delivering the first fuel volume and the second fuel volume to the operator during a second fueling event, wherein a total volume of fuel equaling the first volume of the first fuel and the second volume of the second fuel has a total octane level that falls within a predetermined limit of the selected octane level of the selected fuel product.

A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.

A fuel dispensing system includes that receives fuel from a fuel storage tank, and a blending system in fluid communication with the fuel dispensing unit. The blending system including a fuel conveyance device that receives the fuel from the fuel dispensing unit, and an additive conveyance device that pumps a fuel additive to be blended with the fuel based on a volumetric flow rate of the fuel, whereby the blending system provides a product mixture having a known fuel-to-fuel additive ratio. A hose and a nozzle are fluid communication with the blending system to dispense the product mixture.

A system includes a source, a detector, and a controller. The source is configured to emit electromagnetic energy toward two plies of film. A portion of the emitted electromagnetic energy is within a range of wavelengths. The detector is arranged to detect electromagnetic energy propagating away from the two plies of film. The detector detects electromagnetic energy within the range of wavelengths and generates signals indicative of intensity of detected electromagnetic energy. The controller controls operation of the foam-in-bag system based the signals from the detector. The film is transmissive of electromagnetic energy in the range of wavelengths. When dispensed between the two plies of film, one or both of foaming chemical precursors or foam formed from a reaction thereof is opaque to electromagnetic energy in the range of wavelengths.

A chemical solution supply part for supplementing the chemical solution to the chemical solution storage tank and a purge gas supply part for supplying N.sub.2 gas as a purge gas to the chemical solution storage tank are in communication with the chemical solution storage tank, and a first manometer serving as a pressure measurement part is arranged on the chemical solution storage tank. In addition, a drain piping is connected to a head portion of the plunger pump, and an automatically controlled air-bleed valve, which is an air-bleed mechanism, is arranged on the drain piping. On the other hand, a second manometer is arranged in the middle of the chemical solution supply pipe, and a front end of the solution supply pipe on the downstream side serves as an injection point for the chemical solution S.

Device and method for filling pressurized gas tanks, particularly vehicle pressurized hydrogen tanks, the device comprising a liquefied gas source, a transfer circuit comprising two parallel transfer lines each having an upstream end linked to the liquefied gas source, at least two separate downstream ends intended to be each removably connected to a tank to be filled, each of the two transfer lines comprising: a pump, a vaporizer for evaporating the pumped fluid, a branch for bypassing the vaporizer and a distribution valve(s) set configured to control the flow of fluid pumped and distributed between the vaporizer and the branch line, the device further comprising a storage buffer(s), which storage buffer(s) is(are) connected in parallel to each of the two transfer lines via a set of valves.
