Abstract:
A system determines that a fuel dispensing operation may be anomalous. In response, the system accesses fuel inventory data that indicates fuel levels in a fuel tank within a threshold period. The system determines a measure amount of fuel that left the fuel tank based on the fuel inventory data. The system determines a calculated amount of dispensed fuel associated with one or more fuel dispensing operations within the threshold period. The system compares the measured amount of fuel that left the fuel tank with the calculated amount of dispensed fuel. The system determines that the measured amount of fuel that left the fuel tank is more than the calculated amount of dispensed fuel. In response, the system confirms that the fuel dispensing operation is anomalous and communicates an electronic signal to the fuel dispensing terminal that causes the fuel dispensing terminal to stop dispensing fuel.
Abstract:
Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

Abstract:
An electromechanically operated fuel nozzle having continuously adjustable flow rate settings between a closed position and maximum flow. The fuel nozzle includes a fuel dispensing pipe for dispensing fuel; an electromechanical valve device to control a flow of fuel in the fuel dispensing pipe, comprising an inlet pipe and an outlet pipe. The electromechanical valve device comprises at least one continuously variable flow electromechanical valve to control the flow of fuel; an electronic board for operating the at least one continuously variable flow electromechanical valve; and electric accumulator means for electrically powering the at least one variable flow electromechanical valve and the electronic board such that the predetermined portions provide the particular one of the flow rate settings. The electromechanical valve preferably comprises a servomotor controlled ball valve.
Abstract:
A retractor cord breakaway device is disclosed. The device comprises a first mating portion that holds a hose and a second mating portion that is secured to the end of a retractor cord. The first mating portion is attached to the second mating portion and they are configured to break away from each other when a force greater than a designated force is applied to the hose or between the first mating portion and the second mating portion.
Abstract:
This invention relates to an overfill prevention system for preventing the overfilling of tanks when filling up large tanks from a fuel distribution truck. The system operates by monitoring and automatically controlling the filling process by use of a power take off switch assembly that is connected electronically to a secondary overfill prevention system that is also connected to a signal probe located in the tank that is being filled. In operation, once fuel contacts the signal probe, a communicator signal is sent from the signal probe to a secondary overfill prevention system, which interrupts a looping electrical current through a fuel shut off sensor assembly to a power take off switch assembly along a connecting cable. Once the looping electrical current no longer returns to the power take off switch assembly, an indicator light turns off and a pneumatic switch is flipped, which automatically stops the flow of air from the distribution truck's air tank to the power take off that drives a pump that is controlling the flow of fuel. This stops the flow of fuel to the tank and prevents costly, damaging and dangerous overfills.
Abstract:
Various exemplary devices and methods for heating fluid dispensers, hoses, and nozzles are provided. In general, the devices and methods for heating fluid dispensers, hoses, and nozzles can be configured to heat fluid dispensable by a user into a fuel tank or other type of container. In some embodiments, a fuel dispensing device can include a first passageway configured to pass fluid therethrough and can include a second passageway fluidically isolated from the first passageway and having a heating element disposed therein. The heating element can be configured to heat the fluid passing through the first passageway. The first and second passageways can extend through at least a distal portion of a hose of the fluid dispensing device and through at least a proximal portion of a nozzle of the fluid dispensing device that has a proximal end attached to a distal end of the hose.
Abstract:
The invention relates, in general, to couplings for the connection of lines, such as, in particular, flexible lines, to one another or for the coupling of flexible lines to fittings. For this purpose, a quick-action coupling (1) for coupling together fluid-conducting lines is described, which comprises a first coupling part (3) and a second coupling part (5), as well as a seal (7) for sealing the two coupling parts (3, 5) and a locking mechanism (9) in order to couple together the two coupling parts (3, 5) in a releasable manner. The two coupling parts (3, 5) are equipped with valve arrangements (11, 13). Each of the two valves (11, 13)* comprises an axially displaceable valve (15, 17), with the valve (15) of the first valve arrangement (11) having an opening (150), in which a plunger (152) is mounted so as to move axially. In the state in which the coupling parts (3, 5) are coupled together, the plunger (152) keeps the two valves (15, 17) apart from each other. The plunger (152) can be locked by means of a catch device (110). The locking mechanism (9) is operatively connected to the catch device (110), so that, when the locking mechanism (9) is actuated for decoupling the two coupling parts (3, 5) that are coupled to each other, before disconnection of the coupling parts, the catch of the plunger (152) is released and the two valves (15, 17) are brought together with the respective valve seat (19, 21).
Abstract:
A safety breakaway connector has a male fitting and a female fitting inserted into one another. The female fitting includes a swivel that rotates about an angle to a breakaway portion of the invention. The swivel has a female portion connected to the breakaway portion and a male portion that pivotally connects to a nozzle. The male portion has an axis spaced apart from the axis of the breakaway portion. The male portion rotates or pivots about the female portion subject to a biased cam. The biased cam has a ball bearing that travels within a race formed in the male swivel. The biased cam provides an offset to the connector so that a fuel line in communication therewith avoids an orientation perpendicular to the direction of travel of a vehicle. The breakaway portion then detaches the fuel line cleanly from the swivel that remains with the fuel nozzle.
