Various examples are provided related to low pressure delivery, e.g., less than 250 psi at the point of application, of plural component system from unpressurized parts A and B material supplies. In one example, a system includes a polyurethane spray foam (“SPF”) raw material supply including parts A and B and a fluid handling system that can deliver the SPF raw material at low pressure to a metal spray gun in metered amounts through separate material fluid paths/conduits via a heated hose length and a whip hose. The fluid handling system can also deliver air at low pressure to the spray gun through separate air stream paths so that the air is communicated to the part A and B material conduits forward of the part A and B material input locations, where they are supplied separately to a mixing nozzle that is engaged at an end of the spray gun.

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

A printing apparatus includes a carrying platform on which a substrate is placed, a cartridge configured to store and supply ink, and a print head configured to atomize the ink into ink droplets and deposit the ink droplets on a printing region of the substrate.

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.

The invention refers to a foam dispenser. The foam dispenser is suitable for dispensing foam produced by mixing a foaming liquid and gas, in particular air. Further, the invention refers to foam dispenser assembly, a vessel for storing a foamable aqueous composition and a method for forming foam using the foam dispenser.

A compressed air introduction part (5) capable of introducing compressed air into an air passage (2a) of a cylinder body (2) is provided. The compressed air introduction part (5) has a compressed air exit port (5a) formed in the shape of a ring that extends circumferentially about a cylinder-center axis (C1) of the cylinder body (2). An annular protuberance surface portion (30) is formed on an inner circumferential surface forming the air passage (2a) on an air blowout port (2c) side of the compressed air exit port (5a), and a protuberance surface (30a) of the annular protuberance surface portion (30) is shaped so as to extend from a peripheral edge portion of the air blowout port (2c) side of the compressed air exit port (5a) along the radial direction of the cylinder body (2) and to then gradually curve and extend toward the air blowout port (2c) side.

A reciprocating foamer pump avoids problems encountered when conventional foamer pumps are exposed to freezing temperatures. In particular, the inventive pump provides an extra-secure connection between air and liquid piston members (200,300). Additionally, a tortuous air inlet (210) is provided to the foamer chamber (136) so as to prevent melted liquid from draining and accumulating in the air chamber.

The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.

Provided herein is an ultrasonic-based aerosol generation device capable of ensuring immediate aerosol generation according to puffs and reducing cartridge replacement costs. The ultrasonic-based aerosol generation device according to some embodiments of the present disclosure may include a control main body which includes a vibration member configured to generate ultrasonic vibrations and a cartridge which is replaceable and coupled to the control main body. In this structure, since the vibration member, which is a relatively expensive component, is disposed at the control main body side, the cartridge replacement costs may be significantly reduced. Further, since a vibration transmission member configured to transmit the ultrasonic vibrations of the vibration member to a liquid aerosol-forming substrate is disposed in the cartridge, an aerosol may be smoothly generated.
