An additive injection system includes an additive injection controller operable to: (a) receive fuel data; (b) determine, from the fuel data, a total fuel amount corresponding to a total volume of fuel present in a fuel tank; (c) determine an untreated fuel amount corresponding to a delivered volume of untreated fuel delivered into the fuel tank, the untreated fuel amount determined based on the total fuel amount and a treated fuel amount corresponding to an expected volume of treated fuel expected to be present in the fuel tank; and (d) in response to determining that the untreated fuel amount exceeds an injection threshold, generate an injection signal to initiate injection of fuel additive into a fuel stream of untreated fuel being delivered into the fuel tank via the fuel tank inlet.

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.

The windshield washer fluid dispenser is a self-service station, that is capable of providing a user with high quality windshield washer fluid and the ability to utilize the windshield washer fluid manually. To accomplish this, the device includes a combination of components, that allows one to properly clean the windshield on one's vehicle without the need of an attendant. To accomplish this, the system includes a body, that houses a user-friendly dispenser container, a blend center unit that can instantaneously mix liquids to make a windshield washer solution, and a HID (human interface device) that can dispense the windshield washer solution according to users' needs. Further, the system includes a display device, a payment system, a sign board and necessary accessories that help with the smooth functioning of the system. Thus, the device utilizes simple, user-interactive, and cost-effective technologies to provide the windshield washer fluid dispenser self service station.

The invention relates to a concentrated product storage cartridge for a diluting and dispensing container, comprising an external body, with an open lower end having a closing edge on the lower end thereof; and on the opposite end, there are flaps extending above the cylindrical tube of the external body, comprising a quick-coupling means; an opening for accessing the inner region thereof, where is placed an internal plunger, forming a filling region; and, on the upper end thereof, having quick-coupling means to be attached to the cover of cartridge. Said cover comprises upper ring flaps, arranged in order to interlock with the quick-coupling means of the internal plunger, forming a single assembly with an opening that can engage with the flaps of the external body, which are mounted in a way to provide displacement mobility in both directions downwards and upwards in relation to the internal plunger head.

Systems and methods for packaging beverage components and dispensing beverages are provided. Bag-in-box packages include connectors that contain rotary pumps. Each rotary pump includes a resiliently deformable housing and a rotor that form a plurality of chambers. The bag-in-box package may be incorporated into a dispenser system that includes a touch screen that allows users to input beverage selections.

A secure automated water treatment trailer and method of inserting chemical in a pipeline, the trailer having a frame with at least one axle and a tongue, a base, a plurality of connected walls, a weather proof top engaging each of the plurality of connected walls opposite the base forming an enclosure, a pair of locking doors, a plurality of discharge ports, a plurality of suction ports, a charging port, a skid, a plurality of a controller in communication with each of the pumps and a network, a plurality of pressure gauges, a generator, a plurality of valves, and a plurality of back pressure valves. The secure automated water treatment trailer automatically processes multiple fluids simultaneously into the pipeline. Each fluid has fluid characteristics and a specific gravity.

A fuel additive cartridge for use with a dimethyl-ether fuel system of a vehicle includes a reservoir for storing and dispensing a liquid fuel additive into a flow of fuel in a fill conduit during refueling. The cartridge also includes a dispenser actuated by the fuel flow to selectively dispense the liquid fuel additive from the reservoir. The fuel additive cartridge is intended to attach to a dimethyl-ether fuel system at a location between a fueling inlet connector and a storage tank to facilitate a metered mixing of liquid fuel additive from the cartridge and dimethyl-ether during the re-fueling of the storage tank.

A method of delivering a selected fuel product having a selected octane level to an operator from a fuel dispenser including a blend manifold, a fuel nozzle, and a fuel hose extending therebetween, including the steps of determining a first volume of a first fuel that is retained in the fuel hose upon completion of a first fueling event, determining a first octane level of the first volume of the first fuel, determining a second volume of a second fuel having a second octane level, and delivering the first fuel volume and the second fuel volume to the operator during a second fueling event, wherein a total volume of fuel equaling the first volume of the first fuel and the second volume of the second fuel has a total octane level that falls within a predetermined limit of the selected octane level of the selected fuel product.

A chemical solution supply part for supplementing the chemical solution to the chemical solution storage tank and a purge gas supply part for supplying N.sub.2 gas as a purge gas to the chemical solution storage tank are in communication with the chemical solution storage tank, and a first manometer serving as a pressure measurement part is arranged on the chemical solution storage tank. In addition, a drain piping is connected to a head portion of the plunger pump, and an automatically controlled air-bleed valve, which is an air-bleed mechanism, is arranged on the drain piping. On the other hand, a second manometer is arranged in the middle of the chemical solution supply pipe, and a front end of the solution supply pipe on the downstream side serves as an injection point for the chemical solution S.
