A fluid dispenser (1) for dispensing a cosmetic composition (2) comprises a housing (3), a dispenser head (4), at least one first receptacle (16) being connectable to a first reservoir (5) comprising a first fluid (6), and at least one second receptacle (17) being connectable or connected to a second reservoir (7), the second reservoir (7) being configured to receive a second fluid (8). The fluid dispenser (1) further comprises a mixing area (18) being in fluid communication with the dispenser head (4), the first receptacle (16) and the second receptacle (17). The mixing area (18) is configured such, that the cosmetic composition (2) is generated when a dose of the first fluid (6) is mixed with the second fluid (8) within the mixing area (18).

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.

This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit having a storing part to store the liquid, the atomization unit being configured to generate an aerosol by atomizing the liquid; and a temperature control part configured to control the temperature of the liquid at a given location between the accommodating part (cartridge) and the storing part.

Apparatus and methods for variable-control fragrance dispensing. The disclosed device brings customization to the fragrance industry. Interchanging sub-containers and selecting the amounts of each sub-container allows a user to customize their scents. A mixing chamber contained to receive and mix a variable amount of each liquid from a plurality of sub-containers is described. The mixed liquid is sprayable out a spray head of the device. Selector knobs may be used to control valves which control the variable amount of each liquid dispensed.

Implementations are described for maintaining helium/air mixture within a tube in an evacuated tube transportation system. A first implementation includes a set of helium tanks uniformly fitted along the tube length, where helium is injected with controlled valves that open or close to maintain the desired level of helium. An operations control center (OCC) receives helium concentration levels in the tube and instructs a controller in the tube to release helium into the tube when detected levels of helium is lower than the desired level of helium. Another implementation is described where a capsule traversing the tube may have a source of helium gas that can be released into the tube. A hybrid approach is also described where helium can be released from a source within the tube and from another source within the capsule.

A distributed pump system is disclosed. The distributed pump system comprises a supply source and a support structure arranged on or proximate an agricultural vehicle. At least two fluid distribution elements are mounted to the support structure and are coupled at an inlet to a first conduit to provide fluid communication between the fluid distribution elements and the supply source. An application system including at least two application units is coupled to one or more of the fluid distribution elements by a second conduit. A first monitoring device is associated with a respective application unit and fluid distribution element, and is configured to sense a downstream flow parameter of the second conduit and generate a corresponding output signal. An electronic control unit is communicatively coupled to each of the fluid distribution elements and is configured to dynamically adjust an input parameter of one or more of the fluid distribution elements.

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.

A dispensing system for dispensing a fluid, the fluid being water or a water-based mixture, includes a dispensing unit and a cleaning unit. The dispensing unit includes a connection unit for connecting the dispensing unit to a supply of the fluid, a dispensing head for dispensing the fluid, and a flexible hose for guiding the fluid from the connection unit to the dispensing head. The cleaning unit includes a cleaning attachment unit for attaching the cleaning unit to the connection unit, a cleaning fluid delivery unit configured to deliver cleaning fluid to the dispensing unit via the cleaning attachment unit, and a receptacle unit configured to accommodate the dispensing head and to receive fluids exiting the dispensing head.

A control unit performs control such that, in a state where water does not flow into a water path, an on-off valve is opened to supply air from a second air path to the water path and a mixed solution path to discharge residual water and thereafter supply of the air is stopped.
