By injecting a chemical fluid and a carrier fluid directly at each nozzle, and by then mixing the fluids at each nozzle to produce a mixed fluid, an improved spray system may be provided which does not contaminate the tank or distribution system with chemical fluid and which allows improved spraying with minimal delay. Accordingly, a system is provided on a field sprayer for independently controlling the flow rate of concentrated chemical fluid to individual spray nozzles using a high pressure chemical distribution rail or loop routed to each nozzle and solenoid injection valves to control the flow of chemical fluid to each nozzle independently.

A closing engine including a framework, fluid drivers, and a flow control device. The framework has an inlet that receives a fluid and an outlet that dispenses the fluid. The fluid drivers are supported by the framework and pump fluid toward the outlet. The flow control device is coupled to the framework and is in fluid communication with the inlet, the outlet, and the fluid drivers. The fluid drivers are cooperatively driven by a motive force from fluid flow through the inlet to dispense fluid via the outlet, and to drive the flow control device to distribute diluent to the diluent drivers in a coordinated manner.

An apparatus for creating custom perfumes is disclosed. The apparatus may comprise a body that may hold perfume refills and a mixing chamber connected to the perfume refills via a plurality of valves. The apparatus may be controlled by a microcontroller. The apparatus may receive custom formulas for creating custom perfumes from users. Upon receiving the formula, the apparatus may determine the quantities of perfumes that are to be added from each perfume refill to create the custom perfume. Further, a vacuum pump connected to the mixing chamber is activated. The amount of time required to extract the determined quantity of perfume from the refills to the vacuumized mixing chamber is calculated. Finally, the valves are opened for the calculated amount of time to allow the vacuum generated in the mixing chamber to extract the determined quantities of perfumes from each perfume refill to create the custom perfume.

This disclosure recites a device that includes a body and a coupling near a first end of the body configured to attach to a water source. The device also includes interior tubing inside the body that includes a base portion that receives water into the device via the coupling, a fork that separates the base into a first path and a second path, and an end portion that combines the first and second paths. The device further includes a compartment along the second path that holds a solid, water-soluble substance. The device also includes a first dial that controls an amount of the water that enters the first and second paths. The device further includes a second dial that controls a rate that the water passes through the compartment. The device also includes a nozzle near a second end of the body.

A system and method for delivering materials for deposition is described. The system includes reservoirs for holding materials, heating elements for liquefying the materials (unless they are to be delivered as solids). Once in a desired state, pressure and material delivery systems to move the materials to a deposition nozzle. In the deposition nozzle, or thereabouts, the materials combine and are prepared to be deposited. An agitation element is used to break up the material and push it out of the nozzle tip in an atomized or droplet form. Changes in the material composition/concentration result in adjustment in heat, pressure or deposition agitation.

A liquid object dispenser includes a body, multiple containers (500), a transfer table (110) including multiple container accommodating parts accommodating the multiple containers, the transfer table being able to relatively transfer the container accommodating parts to a replacement position in the body at which the containers are replaced and to a dispensing position in the body at which the stored liquids of the containers accommodated in the container accommodating parts are dispensed, and a liquid object dispensing part configured to cause the stored liquids of the containers accommodated in the container accommodating parts at the dispensing position to be dispensed.

A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.

A system for combining and spraying fluids that includes a principal reservoir for holding a carrier fluid; an electric pump in communication with the principal reservoir; a power source for energizing the pump selectable between a rechargeable 12-volt battery and a 110-volt AC line; at least one auxiliary reservoir for holding an auxiliary fluid to be controllably mixed with carrier fluid being drawn from the principal reservoir; a selector valve for selecting which if any of the auxiliary fluid(s) are to be combined with the carrier fluid; a Venturi tube for combining streams of carrier fluid and selected auxiliary fluid(s) in a predetermined ratio which may be varied as desired; and a spray wand in fluid communication with the Venturi tube for discharging the selected fluids.

A fluid delivery system includes a smart hose. The smart hose includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose. The fluid delivery system further includes master hub disposed on a fluid delivery device. The fluid delivery system also includes at least one slave hub disposed on the smart hose and communicatively coupled to the master hub.

In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.
