Abstract: A self-cleaning nozzle assembly adapted for use in processing pressurized liquids, slurries, etc., which may carry with it particulate matter. A spacing between two nozzle members forms an orifice, and the size of the orifice is adjustable. The nozzle members are spring biased together to reduce the size of the nozzle orifice, but pressurized liquids processed by the nozzle counteract the spring bias force to increase the size of the nozzle orifice.

Abstract: An apparatus for simultaneously filling a set of microcups includes a corresponding number of storage vessels having capillary outlets projecting into the microcups. The distance between the outlets and the bottom of the microcups is adjustable so that the filling quantity of the microcups can be modified depending on the requirements. For discharging fluid out of the storage vessels into the aligned microcups, diaphragms are used which are connected directly to the storage vessels or to auxiliary vessels cooperating with the storage vessels and are acted upon by a pressure plate located above the diaphragms.
