A coating applicator tool head configured for use with a robotic maintenance device includes a tool head body with a frame, a supply container, a drive for actuating delivery of flow of coating from the supply container, a feed tube, a nozzle receiving flow from the feed tube, and a spreading tool such as a roller brush or a spatula receiving flow from the nozzle. The coating applicator tool head is moved by an articulated arm of the maintenance device over surface of a wind turbine blade containing damage such that the roller brush or spatula can apply layers of the coating to cover and fill in the damage. The nozzle directly supplies coating continuously onto the roller brush or the spatula, and the drive can be configured to independently adjust supply of two or more different components in the supply container that may be mixed to form the coating.

A method for spreading a resin paste onto a carrier film includes feeding resin paste into a doctor blade unit having a doctor blade, using a feed device that includes a discharge opening through which the resin paste is fed from the feed device into the doctor blade unit, moving a carrier film on a base surface through a doctor blade gap that is formed between the doctor blade and the base surface, and spreading the resin paste onto the carrier film using the doctor blade. The discharge opening is positioned to be immersed into the resin paste that is in the doctor blade unit during operation of a doctor blade apparatus configured to perform the method. A resin mat installation for producing resin mats, particularly of SMC, includes at least one doctor blade apparatus as described above.

A swimming pool cleaning system for removing stains and deposits on the bottom and walls of a swimming pool. The cleaning system includes a cleaning tool having an elongated handle pivotally secured to a tool head, wherein the tool head dispenses a cleaning solution for removing stains and deposits. The tool head may also include an absorbent or sponge-like material thereon and one or more scrapers to help remove deposits. The tool head is in fluid communication with a container in which a cleaning solution can be stored. The container includes a pump thereon for allowing the user to selectively deliver the cleaning solution to the cleaning tool. Thus, the cleaning system allows a user to more easily remove stains and deposits from the walls and bottom of a pool.

A web transport system for transporting a web of media along a web-transport path including a fluid bar for guiding the web of media, and a scavenger blade positioned downstream of the fluid bar. A liquid is pumped through holes in an exterior bearing surface of the fluid bar, thereby pushing the web of media away from the fluid bar. The scavenger bar includes a blade edge facing the first surface of the web of media, the blade edge being spaced apart from the first surface of the web of media by a gap distance. The scavenger blade removes at least some liquid from the first surface of the web of media as it passes by the scavenger blade, thereby reducing the amount of liquid that is carried along to portions of the web-transport path that are downstream of the scavenger blade.

A roll-to-roll electroless plating system, including a plating tank containing plating solution, and a web advance system for advancing a web of media along a web-transport path that passes through the plating tank. One or more fluid guides are positioned within the plating tank to redirect plating fluid containing gas bubbles introduced by a gas bubble source away from the web of media as it is advanced through the plating solution in the plating tank.

A roll-to-roll manufacturing machine suitable for processing and producing polymer films that contain nanostructures, including but not limited to multifunctional polymer films. The machine applies a liquid polymer on a substrate to form a liquid polymer film, at least partially embeds nanostructures into the liquid polymer film, melt casts a layer of a molten polymer on the liquid polymer film to produce a thin polymer film, organizes the nanostructures in a thickness direction of the thin polymer film comprising applying an electric field to the thin polymer film, aligns the nanostructures in the thin polymer film by simultaneously subjecting the thin polymer film to heat and a field that aligns the nanostructures, and solidifies the thin polymer film to freeze the nanostructures along nanocolumns in a thickness direction of a solidified polymer film resulting therefrom.
