A multi-port dispensing device has a manifold with a top, a bottom, sides, and ends. An inlet conduit and a handle are connected to the manifold with the inlet conduit in communication with an inlet port in the manifold. A plurality of outlet conduits are connected to the manifold with each outlet conduit in communication with an outlet port in the manifold. A bottle or a nozzle are connected to the outlet ports. A shut-off valve on the bottle or outlet conduit permits and prevents flow from the manifold through the outlet conduits.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes first pump mechanism that includes a first displaceable plunger and a first plunger cavity that is disposed along a first flow path for receiving the first fluid and a second displaceable plunger and a second plunger cavity for receiving the second fluid. An actuator includes a selector and an actuator that are movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a fluid dispensing manifold by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the fluid dispensing manifold by causing the second fluid to flow along a second flow path.

An injection port for a spray gun includes a first end and a second end disposed opposite the first end along a longitudinal axis. The injection port also includes an interior passage extending between the first end and the second end along the longitudinal axis, and a plurality of blind bores disposed at the first end, each blind bore extending perpendicular to the longitudinal axis.

A container unit (2) including a plurality of sub-container portions (4) defining a plurality of chambers for containing a liquid substance, a mixing chamber (10) downstream of the sub-container portions, a selecting mechanism for selecting one or more liquid substances from the sub-container portions, and a spray actuator (6) for dispensing a single liquid substance product from one sub-container portion or a mixture of liquid substances from two or more of the plurality of sub-container portions (4), wherein the sub-container portions (4) are individually removable from the container unit.

Provided is a method of coating at least an area of a surface by a Drop-on-Demand (DOD) method, comprising the steps of providing a DOD dispensing head (1) with at least two individually controllable nozzles (2) arranged in a row, which is moved by a robotic device, applying a movement to the DOD dispensing head parallel while maintaining a distance between the nozzles (2) and the surface, wherein the movement comprises a rotation of the dispensing head around an axis perpendicular to the surface, dispensing discrete amounts of a the liquid coating material through the at least one nozzle onto the surface, wherein firing of the at least 2 nozzles is triggered non-synchronously by a control unit.

Disclosed herein are devices, systems, and methods for dispensing fluids. One general aspect includes a multi-chamber fluid dispenser. The multi-chamber fluid dispenser includes a container and a cap. The container has a plurality of chambers formed therein. Each of the chambers in the plurality of chambers is configured to store fluid therein. The cap is for covering the container. The cap includes a distributor through which fluid stored in any one of the chambers in the plurality of chambers is allowed to be expelled from the container Each of the chambers in the plurality of chambers is configured to be in fluid communication with the dispenser such that fluid is dispensable from the container in at least one of the following manners individually as an individual fluid and together as a mixed fluid.

A coupling is provided for the connecting of lines and includes a first coupling disc with first line connectors and a second coupling disc with second line connectors. Moreover, a first drive is provided in order to be able to move the two coupling discs axially with respect to each other. Moreover, a second drive is provided in order to be able to rotate the two coupling discs with respect to each other.

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 size-selective aerosol nozzle that includes an impactor body with an internal enclosed sidewall spanning in a directional longitudinally from a distal end of a distal spray end to a central sidewall terminal end and defining a central spray channel and a fluid segregation member. The segregation member may include an internal enclosed sidewall defining at least one liquid removal channel spanning laterally away from a central spray channel, defining a second aerosol discharge outlet in fluid communication with the central spray channel, and spans into the central spray channel to bifurcate the central spray channel into the liquid removal channel and an aerosol discharge channel. The fluid segregation member has an inner surface defining the liquid removal channel and is in an overlapping configuration with the internal enclosed sidewall to mechanically segregate emitted aerosol spray from the first aerosol discharge outlet of a portable hand-held aerosol spray assembly.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.
