A volatile liquid refueling apparatus, which includes a probe including an outer collar, and a receiver including a receiving collar, where the outer collar of the probe and the receiving collar of the receiver are configured to join to create a vapor-tight enclosure, and where the receiver further includes a locking mechanism whereby the apparatus can be locked in an open position.

A handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter and to modify the functionality of buttons that control scrolling on the display. The control circuitry inverts the orientation of the visual output based on a command provided to the control circuitry by a user or by a position sensor.

A nozzle for dispensing fluid includes a nozzle stem that controls the flow of fluid out of a dispensing end of the nozzle. The nozzle stem includes an overmolded stem tip on a reduced diameter portion of the nozzle stem. The overmolded stem tip is formed from a compliant material and includes a sealing portion and a tip cone extending from the sealing portion.

A valve for a vapour recovery system including a valve body having an inlet and an outlet, a valve seat within the valve body, a valve closure member releasably engageable with the valve seat, a socket portion for receiving a pipe member, a plurality of engagement members configured to be releasably engageable with a portion of a pipe member received in the socket portion for releasably retaining the pipe member in the socket portion, and an actuation member mounted on the valve body. The actuation member includes a recess for receiving each of the engagement members and is displaceable between a first position in which the engagement members are received in the recesses in the actuation member, and a second position in which the actuation member urges the engagement members inwardly towards a deployed configuration in which they engage with and retain a pipe member located in the socket portion.

An electronic cigarette vaporizer is not dis-assembled for filling with e-liquid, but is instead filled from a user-replaceable e-liquid cartridge. The vaporizer includes a front section comprising a wick and heating assembly but no e-liquid cartridge, the front section being removably fitted to a body of the vaporizer to enable a replacement front section to be used once the original wick or heating element starts to degrade, that replacement front section being supplied to the end-user with no e-liquid in it.

The invention is an electronic cigarette vaporizer system operable in a discrete mode to reduce the amount of vapor produced by a vaporizer that forms part of the system, compared to a normal mode. The discrete mode causes the vapor produced to be less visible or noticeable, compared to a normal mode.

An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.
