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.

An aerosol-generating article may comprise a liquid storage portion containing a liquid aerosol-forming substrate, and a hydrochromic material provided on the liquid storage portion. The hydrochromic material has a first colour when in the presence of or when in contact with the liquid aerosol-forming substrate and a second colour when in the absence of or when not in contact with the liquid aerosol-forming substrate. An aerosol-generating system may comprise the aerosol-generating article, an aerosol-generating element, and an aerosol-generating device. An aerosol-generating device may comprise an electrical power supply, an electronic photosensor, and a controller configured to control a supply of electrical power from the electrical power supply based on a value of an optical property sensed with the electronic photosensor.

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.

The invention relates to a nozzle (13) for dispensing a fluid, comprising a manually operated control lever (15), which can be moved between a closed position and an open position in order to control the dispensing of the fluid. According to the invention, the control lever (15) comprises a latching pawl (23), which is designed to engage in a slotted guide (22) of the nozzle (13), the latching pawl (23) being designed to follow an opening movement of the control lever (15) in an opening direction (18) and a closing movement of the control lever (15) in a closing direction (18), the latching pawl (23) being able to be moved, by cooperation with the slotted guide (22), relative to the control lever (15) in a direction perpendicular to the opening and closing direction (18) into a catch position (25), in which the latching pawl (23) fixes the control lever (15) in the open position. Because of the interaction of the latching pawl (23) and the slotted guide (22), a locking device that is easy for the user to operate is created for the control lever by means of a simple design.

Various exemplary devices and methods for heating fuel hoses and nozzles are provided. In general, the devices and methods for heating fuel 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 configured to pass heated air therethrough. The heated air passing through the second passageway can be configured to heat the fluid passing through the first passageway. In some embodiments, a fuel dispensing device can include a single hose configured to pass fluid and heated air through separate passageways therein, and the device can include a manifold configured to facilitate passage of the fluid and the heated air from separate sources into the single hose.

A fuel tank fill assembly includes a fuel fill tube adapted to be coupled to a fuel tank and configured to receive fuel discharged by a pump nozzle. The assembly includes a tube mounting bracket for mounting the fuel fill tube in a stationary position in a vehicle to conduct fuel to the fuel tank. A process for coating the tube mounting bracket is disclosed.

Methods are devices are provided for preventing fracture of a fluid-filled chamber or tank. In general an anti-fracture expansion device can be disposed internally within a fluid-filled chamber such that during a freeze event displaced fluid can compress or flow into the anti-fracture expansion device, thereby reducing the likelihood that the chamber will rupture. The internal disposition of the expansion device prevents it from interfering with other components that may be connected to or adjacent to the fluid chamber, thereby conserving space. In certain embodiments, the expansion device can have a dual function wherein it can act as a flow control valve in addition to functioning as an anti-fracture expansion device.

A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.
