Abstract: A turbine nozzle includes hollow nozzle vanes mounted between outer and inner bands. The inner band includes an integral skirt around the perimeter thereof. A backing sheet of a honeycomb seal is mounted to the skirt to define a cavity therein. The inner band includes supply apertures for providing cooling air into the cavity, and the skirt includes forward and aft purge holes for discharging the cooling air therefrom. During operation, the air channeled through the cavity cools the backside of the inner band and is then discharged through the purge holes.

Abstract: A gas turbine engine component includes a perforate metal wall having pores extending therethrough. The wall has a first surface covered by a thermal barrier coating. The pores have first ends which are covered by the thermal barrier coating, and the pores are ventilated from an opposite second surface of the wall for cooling the thermal barrier coating.

Abstract: A method of imaging media, such as banknotes, is provided. A note is moved with respect to a CCD camera and a variable interference filter (VIF), and a succession of images acquired over time. From the plurality of images covering a range of wavelengths of light, profiles may be assembled of the optical characteristics of the banknote. These may then be compared with reference profiles to detect forged, fake, or unacceptable media. The method may also be applied to a range of types of objects. Also provided is an apparatus for implementing the method.

Abstract: A gas turbine engine exhaust nozzle includes coaxial inner and outer conduits. The inner conduit has a main outlet at an aft end thereof, and a row of radial apertures spaced upstream from the outlet. The outer conduit has an auxiliary outlet at an aft end thereof, and surrounds the inner conduit over the apertures to form a bypass channel terminating at the auxiliary outlet. A plurality of flaps are hinged at upstream ends thereof to selectively cover and uncover corresponding ones of the apertures and selectively bypass a portion of exhaust flow from the inner conduit through the outer conduit in confluent streams from both the main and auxiliary outlets.

Abstract: A flowpath wall is provided for bounding hot combustion gases in a gas turbine engine. The wall includes opposite outer and inner surfaces and a plurality of cooling holes extending therebetween. A thermal barrier coating is bonded to the outer surface and covers blind the holes thereat.

Abstract: A label laminate includes a face sheet with a die cut label adhesively bonded to a release liner. An isolated stealth tie is hidden between the label and liner to effect a locally stronger bond therebetween.

Abstract: A turbine nozzle includes a row of vanes in corresponding segmented outer and inner bands. The inner band of each segment includes a retention flange. A nozzle support includes forward and aft flanges defining a retention slot receiving the retention flange. The retention flange includes a radial lug trapped axially in the retention slot, and a tangential lug at an opposite circumferential end disposed on the forward flange. The aft flange includes an outer hinge, and the retention flange further includes an inner hinge for cradle mounting the retention flange in the nozzle support.

Abstract: A turbofan engine includes a row of fan blades disposed upstream from a row of stator vanes, and is powered by a core engine. The fan blades are serrated for mixing wakes therefrom to attenuate fan noise.

Abstract: A swirl cup for a gas turbine engine combustor includes a tubular body having an inlet at one end for receiving a fuel injection nozzle, an outlet at an opposite end for discharging the fuel, and an annular septum therebetween. A row of first swirl vanes is attached to the septum adjacent the body inlet, and a row of second swirl vanes is attached to the septum adjacent the first swirl vanes and spaced upstream from the body outlet. Air from the first and second swirl vanes is swirled directly around the injected fuel without a flow barrier or venturi therebetween.

Abstract: A turbofan exhaust nozzle includes a jet pipe having a pair of thrust reverser doors disposed on opposite sides thereof. Each door has a hinge arm joined to a swing arm, which in turn is joined to the pipe. Each door also includes a latching clip at a forward end, and a deployment clevis between the clip and hinge arm. A common actuator is connected to both doors by corresponding links joined to the clevises for driving the links aft to pivot aft the doors and swing arms. A first lock selectively locks the latching clip and a second lock selectively locks the swing arms in coordination with the first lock for permitting variable area axial movement of the doors, thrust reverser deployment thereof, and retraction to stowed positions of the doors.

Abstract: A bearing housing includes inner and outer shells through which a rotor shaft may extend. A service tube is fixedly joined to the inner shell and extends through a service aperture in the outer shell. A flexible coupling sealingly joins the service tube to the outer shell at the service aperture for permitting differential thermal movement between the inner and outer shells at the service tube.

Abstract: A laminate is provided for both labeling a data disk and creating an envelope for storing thereof. The laminate includes a base sheet having first and second pages joined together at a primary fold line. Flaps extend along corresponding edges of one of the pages at secondary fold lines in a configuration to form a closed envelope when folded together. A patch is laminated to the first page by layers of adhesive and release. The patch or first page includes a circular diecut defining a removable disk label having the adhesive on the back thereof.

Abstract: A turbine includes a row of blades each having an integral airfoil, platform, and dovetail. Each platform has opposite first and second side edges corresponding with the opposite pressure and suction sides of the airfoil. The platform first side edge is radially higher than the platform second side edge continuously between opposite forward and aft edges of the platform. In this way, adjacent platforms define a down step therebetween for preventing obstruction of combustion gases flowable downstream thereover.

Abstract: Abrasive shot is injected into a carrier stream of compressed gas. The shot and gas stream are directed against a pliant coating. The compressed gas expands at the coating for cooling thereof which decreases coating resiliency for enhancing stripping thereof by the impinging abrasive shot.

Abstract: A document feeder includes advance, separation, and transport rollers for driving checks in turn along a feedpath from an input tray containing a stack of the checks A sensor is disposed between the separation and transport rollers for detecting presence of the checks therebetween. A controller is joined to the rollers for controlling speed thereof, and is operatively joined to the sensor for measuring intercheck gaps between the separation and transport rollers. The controller actively adjusts the intercheck gaps by temporarily changing speed of the separation roller at the beginning of the feedpath near the input tray. The intercheck gaps are measured and corrected between the separation and transport rollers for precise control thereof while maximizing throughput.

Abstract: An RF amplifier module includes PC boards laminated atop a bottom conductor plate. The boards include an RF semi-conductor amplifier chip mounted in a well extending to the bottom plate disposed in electrical connection with the chip.

Abstract: A self-service terminal (SST) fascia (12) comprises a touch-sensitive display (14) capable of displaying a selection of images and at least one further user-interfacing element, such as a card reader slot (18) or a receipt printer slot (22), incorporated within the display (14) so that the display (14) surrounds the user-interfacing elements.
