The nozzle head may be rotated by a motor or self-actuated by tilting the tips out of the plane of the spin axis. The nozzle tips also may be canted radially to undercut and peel away the coating. The nozzle assembly may be continuously or intermittently actuated, fixedly or movably mounted, and used singularly or in plural array. Specific applications are described for descaling metal, cleaning electrolytic bath deposits from electrodes, and removing resinous materials from metal surfaces.Field of SearchWith separate pump, splasher or agitatorWith fluid discharge reaction nozzle With motor therefor Movably mounted, adjustable or removable Work circumposable or opposed fluid-applying jets or plural pipes With closable work-treating chambers With movably or flexibly mounted spray or jet applying conduits or nozzles Jet directed toward or along supporting surface (e.g., lawn rakes) | |
