Abstract: A powder fluidizing system, comprising a pressure vessel, a powder container removably mounted within the pressure vessel, and comprising a bottom sieve; a vibrator generating vibrations and transmitting the vibrations to the powder container above the sieve; and a guide directly secured under said powder container to the bottom sieve; wherein a bulk powder fed within the powder container is vibrated within the powder container and flows through the sieve to the guide, and a powder fluidizing method, comprising feeding a bulk powder within a powder reservoir maintained under pressure; vibrating the powder reservoir; and passing the powder through a sieve positioned at the bottom of the powder reservoir.

Abstract: An apparatus for surface-to-surface application of a liquid media to a substrate. The apparatus comprises a housing and a device movably mounted within the housing. The housing has an external surface and an outlet. The device has an outer surface and an inner cavity for receiving the liquid media. The outer surface includes at least one recess in flow communication with the inner cavity such that liquid media can be delivered from the inner cavity to the recess. As the device moves within the housing, the at least one recess periodically passes by the outlet such as to apply to a substrate being conveyed past the outlet, in surface-to-surface contact with the external surface of the housing, a liquid media in a pattern corresponding in shape to the recess.
