The present invention provides a 2-way air flow type dispenser for spraying powder and a powder sprayer including the same. The present invention adopts a 2-way air flow manner in which an air flow causing the powder to be sprayed and an air flow causing the powder to be transferred from a container to a spraying nozzle are separately formed, thereby enabling the smooth spraying of the powder.

Compositions adapted for use as a hair densifying agent are presented, as well as embodiments of a dispenser for dispensing the composition. A hair densifying system includes a dispenser adapted for dispensing a hair densifying agent with a hair densifying agent disposed therein, the system is substantially as described. The compositions can also be used to modify the color balance in a user's hair.

An applicator for applying fibers to a surface is described herein. The applicator includes a body having a first end and a second end. The first end has a first opening configured to couple to a container housing the fibers and to receive the fibers from the container. The second end has a second opening for dispensing the fibers from the body. The applicator also includes an air flow generating member for creating an air current for propelling the fibers through the second opening as the fibres pass along a pathway between the first opening and the second opening. The fibers are directed along the pathway from the first opening towards the second opening and into the air current by gravity.

A film forming method of forming a film by accelerating powder of a material with gas and spraying and depositing the powder onto a surface of a substrate with the powder being kept in a solid state includes: a substrate film forming step of forming a film. The film forming step includes jetting out the powder and inert gas from a nozzle towards the substrate, causing inside of the chamber to be under positive pressure by the inert gas, and depositing the powder on the surface of the substrate.

The present disclosure provides a sound absorbing material and a preparation method thereof. The sound absorbing material includes a porous powder core and an adhesive coating the porous powder core. A porous powder dispersion solution and an adhesive dispersion solution are simultaneously subjected to spray granulation via a nozzle having an inner ring nozzle and an outer ring nozzle, so that the porous particles having a structure including a porous powder core and an adhesive coating the porous powder core are formed. The porous particles prepared by the method of the present disclosure when serving as a sound absorbing material of a sounding device have high strength and is not easy to be broken. Moreover, a total amount of the adhesive used in the method of the present disclosure is less than that in the conventional method, so that cost is effectively saved.

Vibrational powder applicators and related methods are disclosed. In some embodiments, a vibrational powder applicator may include a powder storage chamber, a powder (e.g., a therapeutic powder) disposed within the powder storage chamber, an actuator operatively coupled to the powder storage chamber and configured to vibrationally agitate the powder when activated, and an outlet in fluid communication with the powder storage chamber. In some embodiments, a vibrational powder applicator may include a flow restrictor and/or a valve.

The present invention relates to a portable spay device and, more specifically, to a portable spray device moving a cartridge member by means of a simple rotational motion of a spray rotating body, thereby enabling powder positioned inside the cartridge member to be effectively sprayed to the outside.

A cutter head assembly for a fiber roving chopper includes a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end. The cylindrical blade cartridge includes a first surface that extends between the cartridge first and second ends and is angled with respect to a central axis of the cylindrical blade cartridge. A second surface extends between the cartridge first and second ends parallel to the first surface and the second surface faces the first surface. A blade body extends between the cartridge first end and the cartridge second end and is disposed between the first surface and the second surface.

A hose-end spreader device includes a hopper configured to contain an amount of granular product, the hopper comprising a hopper inlet and a hopper outlet in communication with the hopper inlet. The device further includes a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the granular product exits the device, and a first impeller disposed in the first chamber. Also included are a housing disposed below the first chamber, the housing comprising a fluid inlet, a second chamber in communication with the fluid inlet, and a second opening in communication with the second chamber through which a fluid exits the device, and a second impeller disposed in the second chamber. The second impeller is coupled to the first impeller.

A dispensing device for connection to a drone is provided. The dispensing device has an outer housing and an inner housing interior of the outer housing. The inner housing has an inner cavity having an entrance opening and an opposing exhaust opening. The area between the outer housing and the inner housing defines an outer cavity adapted to hold a material. The dispensing device also has a fluid access opening to provide fluid access between outer cavity and the inner cavity to allow material in the outer cavity to be transferred to the inner cavity and mixed with air to create an air and material mixture. An air accelerator is provided adjacent the inner cavity to accelerate the air and material mixture out of the dispensing device.
