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.

A device for refueling an aircraft, including a fuel flow duct, the downstream end of which is equipped with a wing coupler for connecting it to an inlet orifice of a fuel tank of the aircraft. The wing coupler includes a body, and a front valve that is movable with respect to the body. The wing coupler includes at least one detection member for detecting the position of the front valve, and an electrical or electronic transmission system for transmitting to a processing unit a signal representing the position of the front valve as detected by the at least one detection member.

A fluid dispensing system generally comprising a dispensing nozzle coupled to a supply conduit; the dispensing nozzle detachably connected to a receiver; a receiver identification device associated with the receiver; an electrical identification circuit being contact-based and including the receiver identification device; an electronics module connected to the supply conduit and arranged to communicate with the electrical identification circuit whereby connection of the dispensing nozzle to the receiver completes the electrical identification circuit and permits communication of at least a unique receiver identifier associated with the receiver identification device to the electronics module.

An apparatus for filling a chambered package can include a dispensing nozzle angled relative to a perpendicular of a machine direction of a carrying mechanism, the dispensing nozzle being disposed adjacent to the carrying mechanism having one or more chambered recess defined about a surface thereof, the dispensing nozzle being configured to dispense a quantity of the medium into the one or more chambered recess defined about the surface of the carrying mechanism. The apparatus includes a housing and at least one wiping material arranged to define an angle having a vertex toward the machine direction about a bottom surface of the housing, the angle of the at least one wiping material being configured to direct any of the quantity of the medium dispensed out of the second end of the dispensing nozzle, but not directed into the one or more chambered recess, into the one or more chambered recess.

An apparatus includes a cover forming an open channel that includes a curved grip portion and first and second sides extending from the curved grip portion. The channel is receivable onto a fuel pump handle of a fuel pump nozzle such that the curved grip portion fits closely over the fuel pump handle and the sides extend downwardly along opposing sides of the fuel pump handle. The apparatus further includes a trigger guard including a first end connected to the first side of the cover by a hinge and a second end that is selectively connectable to the second side of the cover. The trigger guard is rotatable about the hinge from an open position to a closed position in which the trigger guard extends under a fuel pump trigger of the fuel pump nozzle and the second end is connected to the second side.

A fluid filling device is provided, including: a covering unit, a quick-connecting unit and a base. The covering unit is configured to cover an opening portion. The covering unit includes a first flow channel, and the first flow channel is configured to be communicated with an interior of the opening portion. The quick-connecting unit is disposed on the covering unit and communicated with the first flow channel. The base includes at least one joint, a second flow channel and a connection portion. The at least one joint is configured to be assembled with at least one pipe. The second flow channel is communicated respectively with the at least one joint and the connection portion. The connection portion is detachably and communicatedly connected with the quick-connecting unit.

The present invention relates to a personal gas handle device. The personal gas handle protective device is in the form of a sanitary cover capable of fitting over a gas pump handle and trigger to prevent direct contact of a user's hand with the gas pump handle and trigger for improving safety and reducing the spread of germs and bacteria. The sanitary cover has a handle cover portion for covering a portion of the handle of the gas pump, a trigger cover portion having a curved portion for covering the trigger of the gas pump. The sanitary cover can be removed and wiped for reuse and can be easily stored and carried. The sanitary cover is made of flexible plastic enabling a user to squeeze the gas pump trigger with the cover fitted over the handle and the trigger.

A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.
