Patent number: 6835262Abstract: There is provided a pressure bonding system for applying pressure onto at least one tile of a workpiece. This system comprises upper and lower gripper members each having first and second gripper ends. The second gripper ends are connected to each other. The first gripper ends are movable relative to each other to receive the workpiece therebetween. Moreover, an upper pressure applicator assembly is slidably engaged to the upper gripper member. The upper pressure applicator assembly is slidable along the upper gripper member between the first and second ends along a length of the workpiece. The workpiece is placed between the upper and lower gripper members with an edge thereof being adjacent the second gripper ends. The upper pressure applicator applies pressure to the tile(s) upon relative movement of the first ends towards the workpiece to a position adjacent the tile(s).Type: GrantFiled: June 19, 2003Date of Patent: December 28, 2004Assignee: Northrop Grumman CorporationInventors: Carl Reis, Thomas Ambrose, Chandrakant Shah

Patent number: 6668561Abstract: A pressure regulated structure includes a first layer, a second layer, a non-metallic honeycomb assembly, and a vent. The honeycomb assembly is between the first layer and the second layer and includes a plurality of walls forming cells, at least some of the walls including laser-formed apertures to allow fluid communication between cells. The vent is fluidly coupled to the honeycomb assembly, wherein fluid in the cells of the honeycomb assembly may be removed through the vent to decrease pressure in the structure.Type: GrantFiled: June 27, 2002Date of Patent: December 30, 2003Assignee: Northrop Grumman CorporationInventors: Chi H.

Patent number: 6665949Abstract: A drying tool for drying moisture present in cells of a honeycomb core. The tool includes an inflatable bladder compartment having a bendable exterior surface and a plurality of open-ended nozzles protruding from this exterior surface, with each nozzle having a passage in fluid communication with the bladder compartment. A connector element is connectible with a hot air source for delivering hot air into the bladder compartment for subsequent dispatch through the plurality of nozzles. Preferably, the nozzles are situated in a grid formation and are of a generally conical configuration. In use, the bendable exterior surface with the protruding nozzles is bowed or curved to generally configure to the exterior shape of the honeycomb core such that hot air is pinpointed in a grid pattern to drive heated air into the core and thereby cause circulation through the core cells for moisture evaporation.Type: GrantFiled: July 24, 2001Date of Patent: December 23, 2003Assignee: Northrop Grumman CorporationInventors: Carl A. Reis, Doris Andren Reis

Patent number: 6318433Abstract: A pressure application device for applying pressure to a repair patch of a variable contoured aircraft surface, the pressure applicator device is provided with an inflatable pressure bladder. The bladder is configured for applying pressure to the repair patch and is formed of a generally fluid tight elastic material. The pressure applicator device is further provided with at least one variable direction adjustable arm. The arm is disposed in mechanical communication with the bladder for facilitating the application of pressure by the bladder to the repair path upon inflation of the bladder. The bladder is further provided with at least one suction device for providing suction attachment to the aircraft surface. The bladder is attachable to a respective one of the at least one variable direction adjustable arm. The arm facilitates selective attachment of the respective suction device to the variable contoured aircraft surface while maintaining the position of the bladder with respect to the repair path.Type: GrantFiled: September 13, 1999Date of Patent: November 20, 2001Assignee: Northrop Grumman CorporationInventors: Carl A. Reis, Nicholas Thomas Castellucci, John C. Del Ferraro
