Certain embodiments of the present invention provide a fill gun apparatus for interconnection of a pump truck and a pressurized liquid delivery system. The fill gun apparatus can be easily attached and detached from an inlet port to deliver a pressurized fluid, for improved delivery, increased efficiency, increased safety, and decreased waste.

The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration.

A filling system for an electronic cigarette (10) is disclosed in which a nozzle (38) of a liquid dispenser (80) contains a plunger (62) which is biased by a spring (60) into a closed position in which liquid is prevented from flowing through the nozzle (38). In use the nozzle (38) is inserted into an open end (42) of a liquid reservoir (34) for an electronic cigarette containing an air tube (32). The plunger (62) engages with the end of the air tube (32) blocking the air tube (32) and opening the liquid flow path through the nozzle (38). The arrangement of the plunger (62) and nozzle (38) is such that operation of the plunger (62) only occurs when the nozzle (38) engaged within a liquid reservoir (32). A membrane (96) can be provided to prevent leakage from the liquid reservoir (34) when the nozzle (38) is disengaged.

A self-closing spout having a cylindrical housing (10) with a delivery spout where the cylindrical housing is positioned around a cylindrical body (6) having a primary latching system and a secondary latching system for controlling the opening and closing of said self-closing spout when said self-closing spout is attached to a container. A circular sleeve (4) is positioned around the cylindrical body (6) for operating a valve operating system (14). The primary latching system has a latch (9) and an actuator (11) for opening the latch (9) and the secondary latching system has two stepped tabs (8) that engage a lip (10A) on the housing 10 to prevent fluid in a container to which the spout is attached from leaking.

Method for autonomously fueling machinery operating at fracking sites. A fuel tank with a plurality of fuel lines individually coupled to a fuel tank are used. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to machinery tanks to be refueled. A cap is detachably connected to the hoses and machinery tanks to be fueled. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow rate. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.

A co-fueling nozzle incorporating dual spouts, having a nozzle housing, a pair of fuel flow paths provided through the housing, a separate poppet and automatic shut off valve operatively associated with each flow path, such that when fuel or additive flows through the various flow paths, it is dispensed out of separate nozzle spouts, when fuel dispensing is initiated. A single actuating lever operates to open or close the poppet valves of the nozzle, and the actuating lever connects with a pair of independent actuators, that engage with their respective poppet valves and automatic shut off valves, to provide for simultaneous or independent opening and closing of the poppet valves, to allow for simultaneous or separate flow of fuel or additives through the nozzle for co-fueling of a vehicle fuel tank or tanks.
