In one embodiment, a spray cycle is disclosed having first and second periods of flow allowance and purging respectively. In another embodiment, respective sub-portion (4) controllable liquid displacement devices for dispensing one or more of the liquid substances selected from one or more of the respective sub-portions (4) are disclosed.

An automated painting system that includes a robotic arm and a painting end effector coupled at a distal end of the robotic arm, with the painting end effector configured to apply paint to a target surface. The painting system can also include a computing device executing a computational planner that: generates instructions for driving the painting end effector and robotic arm to perform at least one painting task that includes applying paint, via the painting the end effector, to a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one painting task.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

Fluid liners and container assemblies for a spraying apparatus and related methods of use are provided. The disclosed liners include a side wall defining a fluid-containing portion and an open end, a flange extending outwardly from the side wall, and a latching member coupled to the flange, where the latching member includes a retaining feature for releasably coupling the side wall to a lid compatible with the liner. Disclosed fluid containers include a lid having a fluid outlet adapted to couple the lid to the spraying apparatus and a collapsible liner, where either the liner or lid comprises a latch that releasably couples the liner and the lid to each other. Advantageously, the fluid liners and fluid containers can provide enhanced storage options for container contents between spraying operations.

A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.

A clothes treating apparatus includes a cabinet, a steam generator configured to generate steam, and a solution storing container configured to store a solution. The clothes treating apparatus also includes a steam spraying portion that is coupled to the steam generator and that is configured to spray steam and a solution spraying portion that is coupled to the solution storing container and that is configured to spray the solution. The steam spraying portion is configured to spray steam to control air pressure at the outlet of the solution spraying portion.

A refillable fluid container for a fluid dispenser is provided. The refillable fluid dispenser includes a body, an output port and a dispensing mechanism. The body includes at least one wall that defines a reservoir for storing fluid therein. The output port is in fluid communication with the reservoir. The dispensing mechanism is associated with the output port. The dispensing mechanism is selectively operable between a closed position and an opened position. A fluid dispenser is also provided.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

A spray gun has at least one air valve that can be actuated by at least one trigger, having at least one valve inlet region and at least one valve outlet region. The spray gun has at least one material valve designed in such a way that it can be pneumatically actuated by air from the at least one valve outlet region. With this design, the force to be exerted to actuate the actuation element by the user of the spray gun is significantly lower than in prior spray guns, which allows for effortless operation.
