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 fleet fueling system may be implemented with controllers electronically interfacing with fuel dispensers at dispensing stations and communicating via a wide area network with one or more computing device implementing multiple subsystems. Hardware components and subsystems may be configured to avoid operating errors and provide end-to-end functionality, including one or more of: avoiding damage to movable readers that can collect information about assets positioned at fuel dispensing stations, selectively authorizing fuel to be dispensed based on the types and amount of fuel those assets are authorized to receive, quickly and reliably entering information about assets, providing analytics relating to fuel usage per asset, predicting future fuel needs at each of multiple fuel dispensing sites and scheduling fuel deliveries based on predicted needs, and detecting or correcting operating errors in the system.

A fluid supply system adapted for vacuum and pressure cycling of fluid, including a transfer vessel adapted to supply a process canister with fluid drawn from a bulk canister under a vacuum, wherein delivery of fluid from the transfer vessel to the process canister is accomplished with positive pressure. A method is also disclosed of delivering fluid, including drawing fluid under vacuum from a bulk canister and pressurizing the transfer vessel to effect dispensing of the fluid into a process canister for delivery to a location of use.

A fluid nozzle includes an inlet housing configured for connection with a tanker aircraft boom, an outlet housing connected with the inlet and configured for connection with a receiving aircraft receptacle, and/or a sensor configured for determining at least one of a ready status, a contact status, and an articulation angle. The sensor may include a ready sensor, a contact sensor, and/or an articulation angle sensor. A method of connecting a fluid nozzle with a receptacle may include providing a fluid nozzle, providing a receptacle, moving the fluid nozzle toward the receptacle, sensing contact between the fluid nozzle and the receptacle via a contact sensor, and/or sensing, via a ready sensor, that the receptacle is latched with the fluid nozzle.

The spout includes a first and a second member. The first member includes an elongated and generally tubular first main body having two segregated and parallel internal passageways, one being an air duct and the other being a liquid duct. Both ducts are substantially straight and substantially unobstructed along the entire first main body but the air duct ends with at least one constricted opening through which the air circuit exits the air duct. A valve is juxtaposed to the rear end of the first main body and is made integral therewith. The valve engages a valve seat provided at the rear end of a tubular inner conduit inside the second member and in which a rear section of the first main body is slidingly axially movable. The valve is normally maintained closed by a biasing element. The spout may be provided with a child resistant closure (CRC) device.

An apparatus for injecting an additive in a pressurized air conditioning or refrigeration system having a service valve includes a cartridge with a piston, an adapter configured to be connected to the service valve, and a bending unit interposed between the adapter and the cartridge. The bending unit includes a flexible capillary tube having a first end fitting adapted to be connected to the cartridge. The flexible capillary tube has a second end fitting adapted to be connected to the adapter. The flexible capillary tube is adapted to be bent at least at 90 without kinking.

A loading arm includes a stand pipe, a coupler configured to be connected to a tank to deliver a product, and a pipe assembly having a first pipe end pivotally coupled to the stand pipe and a second pipe end pivotally connected to the coupler. The pipe assembly includes a pivot joint disposed between the first pipe end and the second pipe end such that the pipe assembly is movable between a retracted position and an extended position. A linkage assembly has a first portion connected to the pivot joint and a second portion connected to the stand pipe. The linkage assembly is operable to allow for the positioning of the coupler at any of a plurality of points corresponding to the pipe assembly being positioned between the retracted position and the extended position. The linkage assembly is fully supported by the stand pipe such that movement of the pipe assembly does not require manipulating the weight of the linkage assembly.

A vent system for a fuel storage tank and a pressure vacuum valve (PVV) module for use with such a vent system are disclosed. The vent system defines a vent path from the fuel storage tank to atmosphere. An elongate vent pipe extends vertically to a rain cap located at the upper end of the vent pipe. A pressure vacuum valve (PVV) is located in the vent path between the lower end of the vent pipe and the tank. The pressure vacuum valve maintains the vent path in a closed condition unless the pressure in the tank is above or below a predetermined pressure. By separating the PVV from the rain cap and placing it between the lower end of the vent pipe and the tank, it is possible to site the PVV at an accessible level for maintenance.

A container end piece has: an inlet; an outlet; a closure device that is movable between a closed position and an open position; and a connection device for connecting the container end piece on to the tank end piece. The connecting device has: a clamping device that is movable between a spaced-apart position, in which the container end piece can be inserted around the tank end piece, and a clamped position, in which the clamping device co-operates with the tank end piece; and a control device that is actuable between a retracted position and an active position, in which the control device exerts a clamping force on the clamping device in its clamped position.
