Patent number: 7476419Abstract: A method of chemical vapor infiltration and deposition includes stacking a number of porous structures in a stack in a furnace. The stack has a center opening region extending through the porous structures and an outer region extending along the porous structures. A first portion of a reactant gas is introduced to the center opening region. A second portion of the reactant gas is introduced to the outer region. The first portion and the second portion are controlled proportions thereby introducing predetermined portions of the reactant gas to both the center opening region and the outer region. The change in weight of the entire furnace, including contents, is measured during the chemical vapor infiltration and deposition process. The rate of weight change is monitored.Type: GrantFiled: January 25, 2007Date of Patent: January 13, 2009Assignee: Goodrich CorporationInventors: James W. Rudolph, David E. Daws, Dary Zeigler, Afshin Bazshushtari

Patent number: 6937352Abstract: The invention is a device for positioning a hand-held RAM inspection system for measuring the thickness of a RAM coating. In detail, the invention includes a housing containing the RAM coating inspection system, the housing having a longitudinal axis. Three laser distance-measuring devices are circularly mounted on the housing at 120 degrees from each other; the laser distance measuring devices are for determining the required distance and orientation of the RAM inspection system from the RAM coating surface. An electrical controller circuit is coupled to the three lasers and the RAM inspection system for triggering the RAM inspection system to measure the RAM material when the three lasers indicate that the housing is at the proper distance and orientation to the RAM coating surface.Type: GrantFiled: October 6, 2004Date of Patent: August 30, 2005Assignee: Northrop Grumman CorporationInventors: Robert A. Scow, David E. Daws

Publication number: 20040047990Abstract: A hardware assembly is provided for controlling a first portion of gas and a second portion of gas in a furnace. The first portion of the gas is introduced to a center opening region of a stack of porous structures. The second portion of the gas is introduced to an outer region of the stack of porous structures. Most of the gas flows out of the hardware assembly from either the center opening region or the outer region while some of the gas flows out through small holes from the other region. A densification method is also provided with two densification processes in which the gas flows in opposite directions in the two densification processes.Type: ApplicationFiled: September 9, 2003Publication date: March 11, 2004Applicant: GOODRICH CORPORATIONInventors: David E. Daws, James W. Rudolph, Dary Zeigler, Afshin Bazshushtari

Patent number: 4558892Abstract: A duct assembly system for joining duct sections each having a plurality of flat intersecting walls includes angle member connectors respectively associated with the duct walls, each connector being generally L-shaped with one leg portion extending perpendicular to the duct wall and having an elongated channel formed therein and the other leg portion comprising two biased-together flanges adapted for frictionally receiving the adjacent duct wall edge therebetween, each flange having elongated ridges which interlock with elongated ribs on the associated duct wall. Each duct wall edge is embedded in a mastic sealant in a trough in the associated connector, the trough having diverging sides for guiding the duct wall edge thereinto. Connectors on intersecting duct walls are joined by corner members formed of sheet metal and flanged for rigidity and tight fit in the connector channels. Each corner member has flanges for gripping the channel edges of the joined connectors.Type: GrantFiled: November 16, 1983Date of Patent: December 17, 1985Assignee: Quikduc of California, Inc.Inventors: David E. Daw, Arthur F. Vlastnik
