Abstract: A material wear indication system is provided that includes a friction plate capable of engaging a moving surface and a wear indicator. The friction plate includes a wearable portion and a non-wearable portion. In one embodiment the wear indicator is embedded in the non-wearable portion and is prevented from contacting the moving surface until the wearable surface has been sufficiently eroded. When the wear indicator contacts the moving surface it emits a particulate matter that can be detected by a sensor. The sensor is operable to generate an electrical signal that is transmitted to a control unit when the wearable surface has eroded thereby exposing the wear indicator to the moving surface.

Abstract: One embodiment is a unique gas turbine engine combustion chamber including primary and secondary burning zones. Other embodiments include unique gas turbine engine apparatuses, systems, methods, and combinations.

Abstract: An intramedullary nail (20) and related method for fixing a fracture in a long bone. The nail (20) comprises an elongate member (22) having a longitudinal axis (54), a proximal end section (32), a distal end section (34) and a solid central section (24) extending between the proximal and distal end sections (32, 34). The proximal and distal end sections (32, 34) respectively include proximal and distal fastener receiving areas (28, 30) of greater cross sectional dimensions than the central section (24). Each fastener receiving area (28, 30) includes at least one hole (50, 52) extending transverse to the longitudinal axis for receiving a cross fastener (110) adapted to secure to the bone on opposite sides of the elongate member (22). The proximal and distal end sections (32, 34) thereby provide rigid anchoring locations relative to the central section (24) and the central section provides flexibility to promote healing of the fracture.

Abstract: A high pressure cartridge case is provided for firearms with blowback operating systems. The cartridge case is provided with a primer support member that supports a primer in a rearward end of a cartridge case. The support member is slideable rearwardly in the cartridge case when the cartridge is fired. The components expand to seal with the cartridge case to prevent the escape of gas around the support member when the propellant is ignited.

Abstract: A nozzle device defines a passageway including an outlet to discharge working fluid to produce thrust. This device includes a vectoring mechanism having three or more vanes pivotally mounted across the passageway and a linkage pivotally coupling the vanes together. This linkage includes a first arm fixed to a first one of the vanes to pivot therewith about a first pivot axis, a second arm and a third arm fixed to a second one of the vanes to pivot therewith about a second pivot axis, and a fourth arm fixed to a third one of the vanes to pivot therewith about a third pivot axis. A first connecting link pivotally couples the first arm and the second arm together, and a second connecting link pivotally couples the third arm and the fourth arm together. The relative angular positioning of the arms with respect to the corresponding pivot axes and/or the arm links can be varied to define different vectoring schedules with the mechanism linkage.

Abstract: A technique is provided for operating a gas turbine engine that has a combustor with a primary stage and one or more other stages and a first compressor providing an air flow to the combustor. This technique includes driving a variable load device with the rotating shaft of the gas turbine engine and sensing pressure of the air flow and an engine speed. In response to a decrease in loading of the engine by the variable load device: selectively bleeding the air flow as a function of the engine speed and regulating temperature in the primary stage of the combustor as a function of a ratio between fuel flow provided to primary stage and the pressure to prevent engine flame out. In one form, the combustor is arranged as a dry load emissions type and the variable load device includes an electric power generator.

Abstract: A variable geometry turbine comprises a turbine wheel supported in a housing for rotation about a turbine axis with an annular inlet passageway defined between a radial face of a movable nozzle ring and a facing wall of the housing. The nozzle ring is movable along the turbine axis to vary the width of the inlet passageway. A substantially annular rib is provided either on the face of the nozzle ring (such that the minimum width of the inlet passageway is defined between the rib and the facing wall of the housing) or on the facing wall of the housing (such that the minimum width of the inlet passageway is defined between the rib and the nozzle ring).

Abstract: A turbine housing (13) for a radial flow turbine, particularly a turbine used in an exhaust gas turbocharger. The housing has a general volute shape with a substantially annular part extending around the turbine axis and an inlet duct (20) extending therefrom. The inlet duct (20) has a first wall facing part of the outer surface of the annular part of the housing, a pair of spaced webs (44) extending from the outer surface of the circular part of the housing to the first wall, the webs defining a valley (45) therebetween. The arrangement renders the housing stiffer and less prone to fatigue cracking.

Abstract: A method of modifying reformate gas composition downstream of the reformer so that it remains in a carbon-free region, i.e. above the critical oxygen/carbon ratio even at the desired minimum operating temperature. This is accomplished by using staged partial oxidation in a partial oxidation chamber downstream of the reformer. A small amount of air (or oxygen) is added. The net result is an increase in the oxygen/carbon ratio and, thus, a lowering of the required temperature for soot-free operation. Immediately downstream of this partial oxidation chamber, heat can be removed to cool the gas prior to a second stage of partial oxidation. A second stage partial oxidation chamber produces additional water and further increases the oxygen/carbon ratio and further lowers the required gas temperature for soot-free operation.

The nozzle includes the first wall structure opposite a second wall structure. The first wall structure includes a first convergent flap pivotally connected to a first divergent flap. The second wall structure includes a second convergent flap pivotally connected to a second divergent flap. The first wall structure and the second wall structure define the throat along the passage and are reconfigurable to adjust dimensional area of the throat. One or more control valves modulate flow of the pressurized fluid into the passage through a first opening in the first wall structure and a second opening in the second wall structure approximate to the throat to change effective area of the throat by fluidic control.

Abstract: The sensor system comprises an implantable sensor and a user device associated with it. A sensitive liquid is enclosed in the sensor, into which glucose can penetrate. The viscosity of the mixture of sensitive liquid and glucose is measured. The user device, which controls the measurement and its evaluation, is a portable device worn externally on the skin. The viscosity is measured based on the rotation of a measuring element driven by a driving magnet, both disposed in the sensor. The rotation of the measuring element is analyzed based on its decay behavior following switch-off of the driving magnet. In a second embodiment, the viscosity is measured based on the oscillatory behavior of an oscillating element excited to oscillate by a magnet, both disposed in the sensor. The oscillatory behavior is analyzed based on the decay behavior of the oscillating element following switch-off of the magnet.
