Patent number: 7320440Abstract: A spray device, useful for example as a fuel nozzle for gas turbine engines, comprises a body having a bore and a cap member having an orifice, the body and cap member in combination defining a chamber. Fluid passages introduce pressurized liquid into the chamber and direct a flow into the bore, thereby causing a spinning flow to be forced out through the orifice.Type: GrantFiled: February 7, 2005Date of Patent: January 22, 2008Assignee: Pratt & Whitney Canada Corp.Inventors: Lev Alexander Prociw, Joseph Horace Brand

Patent number: 6463992Abstract: A method of manufacturing a seamless self-supporting metal part using nickel vapor deposition, where the part has a selected minimum thickness, a first aerodynamically contoured surface and a second substantially parallel surface. The method replaces labor intensive welding of individually manufactured sheet metal segments for complex aerodynamic shapes, and produces a part with higher accuracy, less cost, controlled strength and hardness properties. Nickel vapor deposition is commonly used for plating electronic components, and for producing a metallic lining for plastic injection moulds. The seamless sheet metal part is cast by: fabricating a mould with at least one mould surface being a negative of the first surface of the part; enclosing the mould in a nickel vapor deposition chamber; depositing nickel on the mould surface by nickel vapor deposition until a blank of nickel is deposited having at least the minimum thickness and an external deposition surface; and separating the blank from the mould.Type: GrantFiled: March 22, 2000Date of Patent: October 15, 2002Assignee: Pratt & Whitney Canada Corp.Inventors: Michael John Dowhan, Joseph Horace Brand, Andreas Eleftheriou, Andrew Robertson Waterston

Patent number: 6123506Abstract: The invention provides a diffuser assembly constructed of internal and external concentrically nested bowl-shaped shells for directing an outward flow of compressed air from a centrifugal compressor impeller to an axially rearward diffused annular flow. The shells can be easily manufactured from nested metal castings thereby eliminating much of the cost and time involved in fabricating prior art diffusers of multiple formed tubes brazed to a separately machined hub. The novel diffuser assembly has two concentrically nested bowl-shaped shells, each shell having an inner peripheral compressor impeller casing about a central opening, and an outer edge. Opposing nested surfaces of the shells have an array of mating grooves separated by abutting seam edges thus defining individual diffuser ducts extending from the compressor impeller casings to the outer shell edges when the shells are secured together.Type: GrantFiled: January 20, 1999Date of Patent: September 26, 2000Assignee: Pratt & Whitney Canada Corp.Inventors: Joseph Horace Brand, Andreas Eleftheriou
