A jet adapter (1) for plastering machines is designed for (semi)automatic application of materials, such as plaster, heat insulation foam, penetrating agent, etc. onto walls Thanks to its design, this unique jet adapter (1) in combination with a smart plastering machine is capable of plastering 1 m of a standard wall in 3 minutes, including plaster trowelling. The application of material onto the wall is performed by especially designed material jets (2) comprising a jet channel (22) and at least two gas feeds (24) entering the jet channel (22) at the slope ranging from 20? to 60? with reference to the axis of the jet (2), which feed the jet (2) with pressurized gas, that in the jet (2) accelerates the supplied material and provides it with energy sufficient for leaving the jet (2).

The invention relates, inter alia, to a device (10) for applying a plurality of threads (17) of a fluid, such as adhesive or lotion, to a moving web-like substrate (11), having a plurality of outlet openings (15a, 15b, 15c, 15d, 15e) for the threads of fluid (17, 17a, 17b, 17c), wherein each outlet opening is disposed between a pair of flow openings (16a, 16b, 16c, 16d, 16e), through which a flow fluid (21), in particular compressed air, flows in order to achieve thread oscillation. The special feature consists, inter alia, in that the outlet openings are disposed along a curved path (22, 22).

In an example, an electrostatic spray module includes a base unit formed of a sturdy, rigid, liquid impermeable, electrically insulative material and a cover formed of a sturdy, rigid, liquid impermeable, electrically insulative material and sized for covering the base unit. The base unit and the cover configured for mating engagement together so as to form a liquid impermeable, electrically insulative, protective enclosure when the module is in a closed state to keep the internal components clean and dry and prevents system form high voltage shorting and prevents leakage of current by inhibiting a high voltage from establishing a return path to ground. The spray module includes a quick access latch and gasket systemwith no tools required to open for maintenance. The module includes integral place holders for components including air supply manifold and variable voltage supply to provide a selectable high voltage level to accommodate various spraying application.

The present invention relates to a dry cleaning technology for a cleaning a surface of an object to be cleaned by adiabatically expanding liquid carbon dioxide to generate sublimable dry ice particles and carrying the dry ice particles on high-speed carrier gas to be sprayed onto the surface of the object to be cleaned, wherein an end of a liquid carbon dioxide nozzle further protrudes to the outside relative to an end of a carrier gas nozzle to prevent a growth of dry ice particles in the carrier gas nozzle, a hydrophobic coating is formed on a surface of the liquid carbon dioxide nozzle to prevent a formation of water droplets and to prevent an occurrence of irregular dry ice particles, thereby effectively preventing damage to a surface of an object to be cleaned and being advantageous in an economical aspect by significantly reducing consumption of liquid carbon dioxide.

The housing has a conduit for receiving paint from an external source into the housing. The at least one nozzle is disposed in the housing. The at least one nozzle has an inlet that is fluidly connected to the conduit to receive paint from the conduit. The at least one nozzle has an outlet that dispenses paint. The least one acoustic emitter is disposed in the housing at a location downstream of the inlet with respect to the conduit.

A makeup machine includes a multi-nozzle spray head and a plurality of needle valves. The multi-nozzle spray head has a main body and a plurality of nozzles. Each of the nozzles includes an interior chamber and an ejection hole, and the interior chamber is communicated with the ejection hole. The needle valves are disposed in the main body and axially aligned with the ejection holes. The needle valves are configured to be axially movable away from the corresponding ejection holes to open the ejection holes and to be axially movable towards the corresponding ejection holes to close the ejection holes. Further, the needle valves are capable of synchronously or individually moving with respect to the main body.
