Patent number: 10544803Abstract: A method of controlling a clearance gap in a rotatable machine and a cooling fluid distribution system are provided. The cooling fluid distribution system includes a component to be cooled having a body extending along a longitudinal centerline of the component and including a radially outer surface at least partially circumscribing the longitudinal centerline. A cooling fluid distribution duct assembly includes a cooling fluid distribution duct extending along and spaced from the radially outer surface for a predetermined length. An outlet hole extends through the cooling fluid distribution duct along a length of the cooling fluid distribution duct. A cooling runner channel is coupled in flow communication with the cooling fluid outlet hole and extends a distance away from the cooling fluid distribution duct toward the radially outer surface. A distal end of the cooling runner channel includes a plurality of cooling holes directed toward the radially outer surface.Type: GrantFiled: April 17, 2017Date of Patent: January 28, 2020Assignee: General Electric CompanyInventor: Neil Fraser Cunningham

Patent number: 9777632Abstract: Splitter apparatus for gas turbine engines are disclosed. An example splitter apparatus may include a splitter including an annular outer wall substantially defining a convex leading edge; an annular splitter support positioned radially within the outer and including a forward end disposed substantially against a splitter inner; and an annular first bulkhead spanning between the outer wall and the splitter support. The outer wall, the splitter support, and the first bulkhead may define a generally annular splitter plenum. The forward end of the splitter support may include spaced apart, radially oriented metering slots. The outer wall may include an inner portion disposed radially inward from the splitter inner surface extending aft and including spaced-apart exit slots. The splitter plenum, the metering slots, and the exit slots may conduct airflow from the plenum, through the metering slots against the splitter inner surface, and through the exit slots.Type: GrantFiled: May 7, 2013Date of Patent: October 3, 2017Assignee: General Electric CompanyInventors: Randall Maurice Prather, Neil Fraser Cunningham, Junhaur Jih, Erich Alois Krammer, Sesha Subramanian

Patent number: 8221058Abstract: The present invention relates to a fresh gas system (1) for supplying an internal combustion engine (4) with fresh gas, in particular in a motor vehicle, having a charging device (8) for increasing the pressure of the fresh gas and having a swirl generator (12), which is arranged upstream of the charging device (8), for generating a swirl, which rotates about the main flow direction of the fresh gas, in the fresh gas, wherein the swirl generator (12) has guide blades (14) with adjustable angle of incidence. In order to be able to produce the fresh gas system (4) more cost-effectively, the swirl generator (12) has a flow guide body (13) on which the guide blades (14) are integrally formed and which, in order to adjust the angle of incidence of the guide blades (14), can be twisted with elastic deformation about the main flow direction starting from an undeformed initial position.Type: GrantFiled: May 18, 2007Date of Patent: July 17, 2012Assignee: Mahle International GmbHInventors: Tristan Fleischer, Neil Fraser

Patent number: 5683700Abstract: The invention concerns a method of prophylactically treating a host against infection by a microorganism, which method comprises administering to the host an attenuated Salmonella bacterium which contains a nirB promoter operably linked to a DNA sequence encoding a heterologous protein. The heterologous protein is expressed in the host and induces in the host an immune response against the microorganism.Type: GrantFiled: June 6, 1995Date of Patent: November 4, 1997Assignee: Glaxo Wellcome Inc.Inventors: Ian George Charles, Steven Neville Chatfield, Neil Fraser Fairweather
