(a) An aerosol including an active material, a binder, and a gas is made. (b) A film-like flow of the aerosol is formed. (c) An electrically-charged region is formed by corona discharge. (d) The film-like flow passes through the electrically-charged region. (e) The film-like flow is introduced into an electric field after passing through the electrically-charged region. In the electric field, an active material layer is formed by adhering a solid component of the film-like flow onto a surface of a substrate by electrostatic force.

An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

An application nozzle for applying a viscous material to workpieces has a nozzle body, through which an application duct extends from a material inlet to a material outlet. The nozzle body has, in a first spatial direction, a width greater than a thickness in a second spatial direction perpendicular to the first direction. The application channel widens towards the outlet in the first direction. A nozzle holder has a main body and two clamping plates. A material feed duct extends through the main body, leading into the inlet at a feed opening. The clamping plates, bearing on opposite nozzle body side faces, fix the nozzle body releasably to the main body. The clamping plates are separate components fixed releasably to the main body and the nozzle body, and/or the nozzle body has two nozzle plates bearing flat against one another, with at least one duct portion between the nozzle plates.

A smooth bore nozzle includes an inlet section having planar converging inlet side walls and top and bottom walls forming an unobstructed rectangular inlet section fluid passageway; a straight section having planar side walls and top and bottom walls contiguous with the inlet side walls and top and bottom walls forming an unobstructed rectangular straight section fluid passageway; and an outlet section having planar converging outlet top and bottom walls and diverging outlet side walls contiguous with the straight section side walls and top and bottom walls, and an unobstructed rectangular outlet section fluid passageway; wherein the cross-sectional area of the fluid passageway remains constant or decreases in a downstream direction, and a perimeter of the cross section increases along a length of the inlet section, and a perimeter of a cross section of the rectangular outlet section fluid passageway decreases along a length of the outlet section.
