A misfuelling prevention device for preventing inappropriate fuel from being added to a vehicle utilizes a diameter difference between a gasoline gun and a diesel gun in order to prevent misfuelling. The misfuelling preventing device is constructed such that when the diesel gun having a relatively larger diameter is inserted, a locking button is not pressed while a flapper is opened, whereas when the gasoline gun having a relatively smaller diameter is inserted, the locking button is pressed while the flapper is not opened. As a result, misfuelling of the vehicle with inappropriate fuel is fundamentally prevented.

A crossover protection system including a product transport vehicle having a tank compartment for containing a liquid product, a fluid property sensor positioned to contact liquid product stored in the tank compartment, a system controller, and a valve coupled to the tank compartment. The valve regulates a flow of liquid product from the tank compartment and has a normally locked state. The system controller may compare a received transported liquid type signal from the fuel property sensor indicative of the type of liquid product in the tank compartment and compare the type of liquid product to a stored liquid product type. If the two types match, the crossover protection controller transitions the valve to an unlocked state to allow the liquid product to unload from the tank compartment. If the two types do not match, the crossover protection controller will disable the valve from transitioning to the unlocked state.

A method and device to insure that a particular dispensing package (18) can only be engaged into an appropriate dispensing location (14). Specifically, the package and the dispenser have mating concentric rings (24, 30) (or portions thereof) to prevent engagement and dispensing of an inappropriate product. In one embodiment, the package (18) is provided with one or more concentric ring projections (24) (or portions thereof) and the dispenser (10) is provided with one or more matching concentric ring recesses (30). The projections and the recesses have similar diameters to define a mating set. In some embodiments, the concentric ring projections are placed on a closure (20), such as a cap, of the package. In alternative embodiments, the projections are placed on the dispenser and the recesses are placed on the package.

A nozzle for dispensing fluid including a nozzle body having a spout and fluid path through which fluid to be dispensed is flowable. The nozzle includes an actuator configured to detect when the spout is sufficiently inserted into a fluid receptacle, and a shut-off device configured to selectively terminate or prevent fluid dispensing operations through the fluid path. The nozzle further includes an interlock operatively coupling the actuator to the shut-off device. The interlock includes a slider that is operatively coupled to the actuator and a pivotable arm that is operatively coupled to the shut-off device, and the slider is slidable along the arm.

An apparatus and system are disclosed for fluid transfer. The apparatus includes a fluid nozzle having a nozzle base. A poppet is rigidly coupled with the nozzle base. The poppet includes a poppet end surface. The fluid nozzle also includes a seal ring having a seal ring end surface disposed between a pull-back collar end surface and the poppet end surface. The seal ring is movable between a first position that prevents fluid flow through the fluid nozzle, and a second position that forms an annular fluid outlet that allows fluid flow through the fluid nozzle. The fluid nozzle also includes a tubular ball ring disposed around an outer surface of the seal ring. The ball ring includes at least one opening for housing a tumbler, which is configured to engage a surface feature of a keyed receiver. The system includes a fluid receiver and the fluid nozzle.

A connection apparatus is used to fluidly connect a storage container and another fluidic device. The connection apparatus utilizes a probe that is inserted into the container to extract fluid from inside the container. A connection piece can be used to connect to the other fluidic device. A support is mounted on the container, and includes a spatial coding that is interlocked with a counter-coding structure. The spatial coding is used to ensure that the correct support is used with the container containing a fluid. A ring element codes the system to indicate the fluid or fluid type.

The invention relates to a removal system for a portable container and comprises an immersion pipe that is mounted in a bung unit that is held in an opening of the container. Furthermore, the removal system includes an extraction head that can be fastened to the immersion pipe. A switch that generates a switching signal whose switching states indicate whether the extraction head is fastened in a target position on the immersion pipe or not is provided in or on the extraction head.

A system for verifying a container of a material before the material is transferred to a process. The system includes a conduit that extends through a mouth of the container. The conduit is supported by an arm that moves between a first position in which the conduit extends through the mouth, and a second position in which the conduit is removed and moved away from the mouth. A reading device extracts information about the container from an information storage element. A computer program receives input regarding the extracted information, receives input regarding the process, and determining whether the container is correct for the process. The program prevents the arm from moving to the first position, and only if the container is determined to be correct does the program allow the arm to move to the first position so that the material can be transferred.

Apparatus, methods and systems designed to prevent fuel storage tanks (above ground or below grade) from being filled or refilled with the wrong type of fuel and/or the wrong grade of fuel by providing a component of a fuel tanker (e.g., drop elbow) and a component of a fuel storage tank (e.g., swivel adapter) that are each specifically and uniquely configured to be product specific, i.e., specific to a particular type or grade of fuel to prevent fuel storage tanks from being filled or refilled with the wrong type and/or the wrong grade of fuel. The component of the fuel tanker and the component of the fuel storage tank may be formed with product specific keys or mating elements that are specific to a particular type or grade of fuel and only mate with a corresponding element or component having the same product specific key or unique mating element.
