Patent number: 9849474Abstract: A selectively configurable spray gun may include a gun body comprising a selectable forward section and a rearward section. The rearward section may be connected with either of two or more selectable forward sections so as to selectively configure the spray gun to operate either with a dense phase powder supply configuration or a with dilute phase powder supply configuration. The rearward section may include a selectable powder flow path that is connectable at an inlet end to a source of dense phase powder and at an outlet end to a selectable spray nozzle in the selectable forward section that may optionally include a diffuser. An adapter may be used to connect the rearward section with a selectable spray nozzle or air cap. A manual spray gun embodiment is also presented. A selectively configurable spray gun for use with a dense phase powder supply may include a smaller diameter powder tube that extends through a larger diameter powder tube.Type: GrantFiled: March 11, 2013Date of Patent: December 26, 2017Assignee: Nordson CorporationInventors: Brian D. Mather, Terrence M. Fulkerson, Thomas Loparo, Michael F. Riley, Benjamin J. Becker

Publication number: 20090061366Abstract: A furnace is heated by a burner that can be selectively operated by either air-fuel or oxy-fuel combustion. The burner comprises a conduit for fuel, a conduit for air, a conduit for oxidant, and control means for regulating flow through the air and oxidant conduits. An air-fuel fired furnace can be modified by addition of the oxidant and fuel conduits and the control means for regulating flow through air and oxidant conduits.Type: ApplicationFiled: October 30, 2008Publication date: March 5, 2009Inventors: LEE ROSEN, Michael F. Riley, Curtis L. Bermel, Hishashi Kobayashi

Patent number: 5366409Abstract: A method and system for providing a controlled gaseous environment at the opening to a receiver and around a free liquid stream downwardly entering the receiver opening. The method comprises laminarly emitting at least two gas flows to extend and intersect over the receiver opening thereby forming an upward plume enveloping the free liquid stream.Type: GrantFiled: November 22, 1993Date of Patent: November 22, 1994Assignee: Praxair Technology, Inc.Inventor: Michael F. Riley

Patent number: 5336085Abstract: An apparatus and method for providing a selected atmosphere at and within an opening to the interior volume of a furnace. Two or more paralleled diffusers adjacent to the furnace opening laminarly emit different fluids and provide a multilayer fluid curtain over the opening. The curtain has a composite modified Froude number from 0.05 to 10, and a thickness at emission of at least 5% of its extent in the flow direction. Partially covering the outside of the curtain is an optional, substantially flat, outer shield with an aperture coinciding with the furnace opening, which reduces the necessary flow rates of fluids. Optional side shields around the sides of the curtain also reduce the necessary fluid flow. A preferred diffuser comprises a porous tube in a housing with an outlet directed to emit fluid across the furnace opening. The outlet is covered with a screen to disperse the fluid flow and to protect the porous tube.Type: GrantFiled: November 6, 1992Date of Patent: August 9, 1994Assignee: Praxair Technology, Inc.Inventors: Sudhir K. Sharma, Michael F. Riley, Mark S. Nowotarski, Alan R. Barlow

Patent number: 5171511Abstract: A tuyere and method for discharging an agitating gas into the molten contents of an electrically heated furnace to reduce temperature and composition variations in its contents. The tuyere comprises a refractory plug and sleeve for installation into the refractory wall and shell of the furnace, and a dielectric section in the tuyere pipe outside the furnace shell to prevent electrical arcing and current flow into the gas supply piping and external supports.Type: GrantFiled: December 12, 1990Date of Patent: December 15, 1992Assignee: Union Carbide Industrial Gases Technology CorporationInventors: Sudhir K.
