A mixing apparatus includes: a first introduction port that is provided on a further upstream side than a mix acceleration part in a mixer tube and allows introduction of a liquid agent; a second introduction port that is provided on the further upstream side than the mix acceleration part in the mixer tube and allows introduction of a substance for removing the liquid agent; and a piston that is provided on the upstream side of the mixer tube and that opens one of the first introduction port and the second introduction port and closes another of the first introduction port and the second introduction port by stroking in the axis direction of the mixer tube.

A system is provided that includes an advisor device; a user device; and a dispensing device. The advisor device and the user device are configured to perform a communication session with each other that includes transmitting, from the user device to the advisor device, information that includes a desired cosmetic product and information related to a user of the user device; analyzing, by the advisor device, the information received from the user device; and generating and transmitting a recommended cosmetic formula to the user device. The user device is configured to transmit the recommended cosmetic formula to the dispensing device for dispensing the desired cosmetic product.

A refillable solution dispensing device includes a housing having an upper section and a lower section. An actuator exposed through the exterior of the upper section. The actuator is movably connected to an air chamber and a solution chamber. The solution chamber is in fluid communication with the solution reservoir and a discharge nozzle. The air chamber is fluidly connected to the discharge nozzle. The actuator is coupled to a mixing shaft that protrudes into the lower section. The lower section comprises an interior volume that functions as a solution reservoir. A solution cartridge and water are inserted into the solution reservoir. A solution mixer is rotatably coupled to the mixing shaft combining the solution within the solution cartridge, the solution cartridge, and the water into one solution. Upon an activation of the actuator, the solution and the air will mix and exit the discharge nozzle.

A spray disk includes multiple nozzles at an outer perimeter of the spray disk, a center hole, and multiple partitions. The partitions are arranged around the center hole and have the center hole as an inner perimeter. Each partition includes an air inlet to receive compressed air, a liquid tank to store a liquid, and a corresponding nozzle from which to spray the liquid with the compressed air. The spray disk can be used in an automatic makeup machine.

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.

Tunable thermoplastic polymer sealants and tunable conductive thermoplastic polymer sealants, and edge seals and fillet seals produced from such sealants; and substrates, components and objects comprising the tunable edge seals and fillet seals, and methods for making and applying such edge seals and fillet seals are disclosed.

A ground sprayer includes a front portion and a rear portion. A marking fluid is stored in a fluid reservoir removably mounted in the front portion. A pump disposed in the front portion draws the marking fluid from the fluid reservoir through a manifold, and the pump drives the marking fluid out of a nozzle. An actuator is disposed in the rear portion and can activate the pump based on a command from the user. The rear portion includes a handle such that the user can fully support and operate the ground sprayer with a single hand.

Infectious diseases may be acquired in public areas such as transportation terminals, shopping centers, schools, hospitals, restaurants and hotels. Large surface areas may be disinfected using a spray system to distribute a suitable fluid such as a disinfectant. Many existing spray systems are large and unwieldy causing operator fatigue. Some spray systems have large, heavy external tanks that provide fluid to the spray system using an external fluid hose. Disclosed is an improved portable spraying system that may be carried by a system operator. The improved system has a tank, a pump, a valve, a nozzle, and a fan all powered by a battery. The tank, the pump, and the battery are arranged to minimize operator fatigue. With the valve set to the priming position, fluid recirculates to prime the pump. Once the pump is primed, the valve is turned to the spray position to begin spraying.

A swivel connector for a spray gun includes a first portion, the first portion including a first interior passage that extends entirely through the first portion along a longitudinal axis and a second a second interior passage that extends along a first axis perpendicular to the longitudinal axis. The swivel connector also includes a second portion coupled to the first portion, the second portion including a third interior passage that extends entirely through the second portion along the longitudinal axis, and a fourth interior passage that extends along a second axis perpendicular to the longitudinal axis. The swivel connector also includes a connector pin coupled to both the first portion and the second portion, wherein the connector pin includes a fifth interior passage that extends along the longitudinal axis.

A device for dispensing a formulation of at least two compounds selected from a set of selectable compounds includes a plurality of containers storing the different selectable compounds, a pump associated with each container, a dispensing surface that includes at least two through openings configured to convey at least two selected compounds, a selector configured to connect the at least two through openings to the pumps for the selected compounds and to close the other pumps, and an actuator configured to activate all of the pumps and to only deliver the at least two selected compounds onto the dispensing surface.
