  • Methods of making self filtering nozzles
    Patent number: 3955953
    Abstract: One end of a glass tube is packed with glass powder of a predetermined size. The combination is then sintered to produce a filter within the tube. The resultant tube and filter are thoroughly washed in the direction toward the other end of the tube. The other end of the glass tube is melted to form a restriction to the flow fluid. The other end of the tube is then ground down until a microscopic orifice appears. The resultant structure is a self filtering nozzle of an exceedingly small diameter with a very low propensity to clog.
