Fuel delivery vessels and vehicles are described. Some embodiments include nozzles for access by an operator. Some embodiments include optimized size and material characteristics. Some embodiments include various dispensing systems.

Provided is an airless compact container. The airless compact container blocks air from flowing into a refill container through a pumping member and thus prevents contents from being corrupted by inserting the refill container provided with the pumping member into one side of a middle case and then allowing contents to be discharged to the upper surface of a content outlet part through the pumping operation of the pumping member when a user pressurizes the lower end portion of the refill container.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

An interlocking telescopic rod-type defense spray apparatus includes: a first tube body, a cap and a second tube body. The first tube body has a receiving chamber for placing an irritant gas can. The cap covers the receiving chamber. A rod body portion of the second tube body includes an upper tube, a lower tube, and a telescopic-rod packing device connecting the upper tube and the lower tube. Two sectioned tube pieces and a spring pin component and a push joint component between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a press-lever spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces.

A substrate treatment apparatus includes a substrate treatment unit configured to provide a chemical solution to a substrate to treat the substrate, and a chemical supply unit configured to supply the chemical solution to the substrate treatment unit. The chemical supply unit includes a loader configured to load a canister containing the chemical solution to the chemical supply unit, a clamp configured to clamp the canister in place, a chemical supply line through which the chemical solution is supplied to the substrate treatment unit, and a coupler configured to couple the chemical supply line to the canister.

A refuelling stand that is lightweight and easily portable which includes A refuelling stand for conveying fuel from a fuel source into a fuel receptacle comprising: a funnel which is optionally collapsible; a conduit having a first end for removable attachment to the funnel, and a second end for engagement with the fuel receptacle; and three or more support legs, wherein each of the support legs is independently movable from a first use mode to a second storage mode. The conduit can be made of flexible material which may be rolled up for storage alongside the support or may be formed of inflexible tubing. The refuelling stand may optionally include at least one stabilizing element.
