Abstract: A spray nozzle comprising an orifice piece is described where a nanoparticle-laden resistive material is provided with the orifice piece. Moreover, the nanoparticle-laden resistive material is physically formed to provide a measurable wear characteristic parameter, measurable by electrically energizing the nanoparticle-laden resistive material, indicative of an operational performance status of the spray nozzle. Embodiments of the present disclosure facilitate formation, application, and update of spray nozzle operational performance models to spray nozzle instances.

Abstract: An apparatus for filtering a suspension has a housing with an inlet receiving the suspension to be filtered, an outlet for the clear filtered filtrate, and a drain for removal of filter cake. The housing has a cylindrical part centered on an axis. An output ring pipe is connected to the outlet and externally surrounds the cylindrical part. A plurality of segmental filter holders are fittable into the cylindrical part from above and together form a circular insert with each holder forming an inlet chamber having an outflow fitting connectable to the annular output pipe. Respective sets of filter elements each formed by a respective strip-shaped support and a mesh filter sock surrounding the support are carried on the holder and open into the respective inlet chambers. A removable cover upwardly closes the cylindrical part above the inserts.
