  • Linear nozzle with tailored gas plumes
    Patent number: 6258166
    Abstract: There is claimed a method for depositing fluid material from a linear nozzle in a substantially uniform manner across and along a surface. The method includes directing gaseous medium through said nozzle to provide a gaseous stream at the nozzle exit that entrains fluid material supplied to the nozzle, said gaseous stream being provided with a velocity profile across the nozzle width that compensates for the gaseous medium's tendency to assume an axisymmetric configuration after leaving the nozzle and before reaching the surface. There is also claimed a nozzle divided into respective side-by-side zones, or preferably chambers, through which a gaseous stream can be delivered in various velocity profiles across the width of said nozzle to compensate for the tendency of this gaseous medium to assume an axisymmetric configuration.
    Type: Grant
    Filed: August 23, 1999
    Date of Patent: July 10, 2001
    Assignee: Alcoa Inc.
    Inventors: David D. Leon, Robert L. Kozarek, Adel Mansour, Norman Chigier
