Patent number: 6665948Abstract: A drill bit penetration measurement system and method for determining a depth of penetration of a rotating drill bit in a bore. A first sensor outputs a first signal representative of a displacement of the leading edge of the drill bit in the bore. A second sensor outputs a second signal representative of a force applied to the leading edge of the drill bit. A processor outputs a third signal representative of the depth of penetration of the leading edge of the drill bit when the leading edge of the drill bit passes from a first medium having a first density to a second medium having a second density. The third signal is based on the first and second signals.Type: GrantFiled: September 5, 2002Date of Patent: December 23, 2003Inventors: Scott Hal Kozin, Joseph C. McGinley, Scott T. Porter

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: 6665950Abstract: Known gas-heated infrared radiators for infrared drying units have a radiator housing (1) that is subdivided by a gas-permeable burner plate (5) in a distribution chamber (6) for the gas-air mixture and a combustion chamber (7), the front side of which emits the radiation. The radiator is held by mixing tube (9) that is affixed to the rear side. A gas-air mixture is supplied to the distribution chamber (6) via said mixing tube (9). The mixing tube (9) has a gas nozzle (11) with a gas inlet (12) and an air inlet (17) on the end opposite the radiator housing (1). The mixing tube is affixed to a holding frame of the drying unit. In order to disassemble the infrared radiator from the infrared drying unit and to mount said radiator on said unit as rapidly as possible, the rear side of the radiator housing (1) is connected to the holding frame by releasable fixing means (20, 33-36) that can be released manually from the front side.Type: GrantFiled: April 24, 2002Date of Patent: December 23, 2003Assignee: Krieger GmbH & Co., KGInventors: Uwe Riepe, Richard Aust, Peter Arlinghaus, Juan Paniagua, Frank Schicht

Patent number: 6665951Abstract: Spin drying of a stack of flats such as egg trays is performed within a housing by movement of a rotatable lifting head into engagement with the undersurface of the stack. A stack lifting device lifts the lifting head and the stack of flats positioned thereon vertically upwardly into engagement with a drive engagement device thereabove which is rotatably powered by a drive with an optional braking device. Operation of the drive will cause rotation of the lifting head, the stack of flats and the drive engagement device simultaneously. The stack of flats will be held between the lifting head engaging the lower surface thereof and the drive engagement device engaging the upper surface thereof for fixedly securing these three elements together during powered rotation thereof. The rotation will spin off any liquids remaining on the flats such as would be present after being washed.Type: GrantFiled: August 22, 2002Date of Patent: December 23, 2003Inventor: Jeffrey B. Kuhl
