A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.

An apparatus (200) for smoothing a surface of an object (100). The apparatus includes a chamber (210), a reservoir (324) configured to hold a liquid (322), and a nebulizer assembly (212) configured to generate a mist (104) from the liquid into the chamber. The nebulizer assembly includes a mesh (732), a vibrating element (731), and a wick (736). The object is received in the chamber and the mist is configured to surround the object.

An anti-condensation housing includes a connector to connect to a diffusing head configured to nebulize a product to diffuse. The housing includes a conduit having an inlet for a nebulized product, an outlet opening at a diffusing end, of the conduit, a fan at an insufflating end of the conduit. The fan generates a flow of air between the insufflating end and the diffusing end of the conduit. An internal surface of the conduit extending along a direction perpendicular to the direction of the air flow creates an obstacle for the progress of the air flow in the conduit. A retainer to retain the nebulized product stopped by the internal surface. A device to diffuse a product implementing the anti-condensation housing and a method for diffusing a product using such a device are provided.

A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.

The mist generating device includes a housing 11 having a water tank 12; a shaft portion 13 provided in the housing and extending in a vertical direction; an impeller 14 disposed on the shaft portion to be rotatable by means of the motor in a horizontal direction about a rotation axis that is the shaft portion; a nozzle 15 for jetting the water in the water tank toward the impeller; and a pump 21 for delivering the water in the water tank to the nozzle. The impeller includes a plurality of blades 14a arranged along a rotation direction of the impeller and configured to collide with the water jetted from the nozzle. The water jetted from the nozzle collides with the blades to thereby smash the water and generate mist. The housing includes a mist releasing port 18 for releasing the mist generated in the housing outwardly of the housing.

An electrostatic spray device includes an electrostatic mixing chamber and an electrode pair in the electrostatic mixing chamber. The electrostatic mixing chamber receives an airflow that is driven by a fan of the electrostatic spray device. The electrostatic mixing chamber also receives a flow of fluid from a reservoir of the electrostatic spray device. The electrode pair is configured to apply electrostatic charge to droplets of the fluid suspended in the airflow. A voltage level of the electrostatic charge is adjustable responsive to a first DC output from a first DC convertor. A flow volume of the fluid from the reservoir is adjustable responsive to a second DC output from a second DC convertor. In some cases, a control unit of the electrostatic mixing device modifies the first or second DC outputs based on a target level of the voltage level or the flow volume.

A fine particles space placement control system includes a fine particles generator configured to generate fine particles in a predetermined space by applying external energy to a liquid or a solid and an irradiator configured to remove some of the fine particles generated by the fine particles generator by irradiating the some fine particles with infrared light.

A shisha device comprises a cooling element (13) disposed along an airflow channel to cool an aerosol. The cooling re) element unit utilizes active cooling and may additionally utilize passive cooling. The cooling element may comprise a conduit (21) comprising a thermally conductive material. The cooling element may be integrally formed with an accelerating element (14) disposed along the airflow channel. Cooling may occur before or during acceleration of the aerosol by the accelerating element. The cooling may contribute to the condensation in the aerosol.
