Disclosed is an apparatus for preparing and dispensing a lubricant and coolant liquid product including a body with a base that defines a support surface for at least one container of an additive product and having a collection tank above which the container can be positioned, a storage reservoir of water suppliable from a water source, a mixing unit in communication with the reservoir and with the at least one container of the additive product, to mix the water and the additive product in a predetermined concentration, first pumping means adapted to pump the water from the reservoir toward the mixing unit, a control unit to control at least the first pumping means, and a dispensing circuit for dispensing the lubricant and coolant fluid obtained in the mixing unit. The body further includes a containing structure that encloses one, several or all the aforesaid components.

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.

A fuel dispensing system for dispensing fuel into a vehicle comprises a stationary fuel tank adapted to contain a quantity of fuel. At least one fuel dispenser is in fluid communication with the fuel tank via piping. A pump is operative to transfer fuel from the fuel tank to the fuel dispenser. A level detector is located in the fuel tank. A tank monitor is in electronic communication with the level detector, the tank monitor being operative to produce information indicative of the quantity of fuel in the fuel tank. The fuel dispensing system further includes a fuel additive injection assembly comprising an additive reservoir configured to contain a quantity of fuel additive. A controller is in electronic communication with the tank monitor to receive information indicating a delivery of fuel into the fuel tank, the controller having a processor and memory operative to execute instructions determining when an additive quantity should be provided. Additive piping defines a flow path extending between the additive reservoir and a discharge location. A valve is situated along the flow path, the valve being in electronic communication with the controller to open so that the fuel additive will flow along the flow path. A meter is also situated along the flow path and is operative to measure a flow of the fuel additive, the meter being in electronic communication with the controller.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

A chemical dispensing device includes a turbine having a diluent inlet and a diluent outlet; a pump having a chemical inlet and a chemical outlet, wherein the pump is connected with and actuated by rotation of the turbine; a mixing chamber having a mixing inlet and a mixing outlet; wherein the diluent inlet is configured for direct connection with a supply of pressurized diluent; wherein the pump inlet is configured for connection with a supply of chemical concentrate; wherein the diluent outlet and chemical outlet are in fluid communication with the mixing inlet of the mixing chamber. The chemical dispensing device of the present disclosure may further include a backflow preventer separating the diluent outlet from the mixing inlet and being configured to prevent flow of fluid from the mixing chamber to the diluent outlet. An associated method of diluting and dispensing a chemical concentrate is also described.

A fluid product dispenser is sized to removably receive a product package containing a supply of the fluid product. The product package includes an internally integrated fluid pump, and the dispenser includes a drive unit powered by flow of a fluid. Flow of the fluid powers the drive unit, which in turn drives the pump internal to the product package, resulting in dispensation of the fluid product in a product/fluid ratio that is independent of the fluid flow rate.

A drinking vessel is provided with a nesting reservoir system for containing and dispensing metered amounts of liquid beverage enhancer. Multiple metered doses can be dispensed, with multiple refilling of the drinking vessel. The concentrated enhancer is metered by the rotation of a knob that rotates a plunger mechanism into a reservoir volume chamber, with one rotation being calibrated to deliver a single dosage of liquid enhancer. All parts can be easily removed, cleaned and then re-used.

The present invention relates to a kit of parts (1), comprising plurality of hose connection parts (2,3) selectable from, first hose connection parts (2) comprising one fluid inlet (5) and one fluid outlet (8), second hose connection parts (3) comprising two fluid inlets (7,8) and one fluid outlet (9), and third hose connection parts comprising three fluid inlets and one fluid outlet, which kit of parts (1) is suitable for assembly a hose connection (61,82,83,64) having at least a first and second fluid inlet and a fluid outlet, according to any one of three configurations. The invention also relates to a fuel dispensing unit (85) for refueling vehicles and a method for assembly a hose connection.

A system and method for mixing and dispensing two substances are provided. The system includes: a first substance a first container for containing a first substance, a second container for containing a second substance, a feeding tube, and a pumping system connected to the first container, the second container, and the feeding tube; wherein the system comprises at least three modes of operation: combining the first and second substances into one combined substance, mixing the combined substance, and dispensing the mixed substance; and wherein the pumping system is adapted to perform the at least three modes of operation and dispense the mixed substance to the feeding tube.
