摘要： The present invention is directed to a unique gear set (10) including a conical involute pinion (14) and a mating face gear (12). The mating face gear has an axis (GA) whose location and orientation is usually configured as intersecting with or slightly offset from the pinion axis (PA). The pinion teeth (16) are formed as involute helicoids generated from a base cylinder. The mating face gear teeth are defined by the shape of the mating conical pinion teeth surface at the time when the two mating gears are specifically positioned so as to perform synchronous rotations about their respective axes of rotation. This arrangement allows the gears to mesh and transmit high torque at high speeds through an angle as required in helicopter transmissions and the like.

摘要： A method for fabricating a composite structure such as an aircraft radome (20) includes preparing seamless female support mold (76)/caul plate (78) tooling, and seamless male support mold (114)/vacuum bag (124) tooling. An uncured composite structure is collated on the external surface of the male support mold (114)/vacuum bag (124) tooling, and then transferred to the female support mold (76)/caul plate (78) tooling for curing. The female support mold (76)/caul plate (78) tooling defines the outer surface of the final composite structure (132), permitting the outer surface to be smooth and of an aerodynamic shape.

摘要： A method of producing intact islets of Langerhans in an insulin producing condition uses a mixture of Hank's solution and 10% by volume fetal calf serum to ductally distend the human pancreas. The exocrine tissue of the pancreas is digested at about 37 DEG C. by an enzyme preparation of collagenase, trypsin and proteolytic enzyme present in the mixture at a level of about 0.2% by weight. The digestion is monitored at regular intervals during the process. The digested pancreas is comminuted, filtered and intact islets of Langerhans are recovered. The recovered islets retain their insulin producing properties.

摘要： A renewable energy source ejector rack (10) for retaining and releasing stores on an aircraft, which has on-board pressurization capability, employs a single pressurization system for two or more release mechanisms (64, 66), and uses air or other clean non-pyrotechnic pressurized gases both as the energy source and as the transfer medium. The aircraft contains a miniature compressor (36) and purification system. Ambient air is filtered, dried and stored as an energy medium. Since the compressor system is onboard, the pressure can be constantly maintained regardless of temperature change. Using purified air eliminates the excessive cleaning burden imposed when using state-of-the-art pyrotechnics, and eliminates the sealing problems associated with hydraulics.

摘要： A direct diode laser system (400) includes N laser head assemblies (LHAs) (400A, 400B, etc.) generating N output beams and generating N received output beams, and a torch head (500) recollimating and focusing the N received output beams onto a single spot. Preferably, each of the laser head assemblies (400A, 400B, etc.) of the direct diode laser system (400) includes M modules generating M laser beams, wherein each of the M laser beams has a corresponding single wavelength of light, M-1 dichroic filters (420), wherein each of the M-1 dichroic filter (420) transmits a corresponding one of the M laser beams and reflects all other wavelenghts, and a fiber coupling device (460, 462, 464, 466) collecting the M laser beams to produce a respective one of the N output beams. In an exemplary case, the M-1 dichroic filters (420) function as band pass filters. A method of generating a high fluence, high power laser beam is also described.

摘要： The present invention provides a slotted cam control system for controlling pitch angles of fan blades (75) of a relatively low-pressure-ratio fan (27) within a fuselage of a helicopter (11). A force-receiving arm (65) of a slotted cam control system receives left and right forces from corresponding left and right foot rudder pedals. An end of the force-receiving arm (65) fits into a V-shaped cam. Next, the end of the force-receiving arm (65) passes the fulcrum of the V-shaped slot (69) and passes along a second predetermined distance of the V-shaped slot (69) in order to increase the pitch angles of the fan blades (75) as the opening of the direct jet thruster (33) corresponding to the depressed foot rudder pedal. A force-applying arm (71) is connected to the end of the force-receiving arm (65) that moves within the V-shaped slot (69), and this force-applying arm (71) applies to each of the fan blades (75) to change the pitch angles.

摘要： A method of determining pressure requires that a three-dimensional surface of an object (14) be covered with a pressure sensitive coating. Next a raw first image (74) is acquired while the object (14) is not under test and a raw second image (74) is acquired while the object is under test. The raw first image (74) and the raw second image (74) are adjusted for a dark image (76) to form an adjusted first image and an adjusted second image. The adjusted first image and the adjusted second image are mapped (78) from a two-dimensional representation onto a three-dimensional model, to form a first model and a second model. A ratio model is formed (80) by taking the ratio of the intensity of the first model and the second model. Finally, a pressure is determined (84) for every surface that forms the three-dimensional model.

摘要： Improvement of radar signal-to-noise ratio and detection sensitivity in radar systems is achieved by methods employing the subtraction (27) of the unwanted radio frequency interference, RFI, or 'clone' signals thereof, from the total received signal. The Clone signals are appropriately adjusted in phase (14) and amplitude (16), and are obtained from an auxiliary broad beam antenna or from a delayed sample from the system's principal antenna. When multiple RFI signals at different frequencies are present, the entire receive band is subdivided into a plurality of frequency sub-ranges.

摘要： A nose assembly (26) and method for controlling the rotation and stabilizing the orientation of a vehicle (10) during landing maneuvers. The vehicle (10) includes a nose assembly (26). The vehicle flap assembly (30) includes an actuator (32) and a flap (38a) from and between a fully retracted position and a fully extended position in response to a guidance signal received from a flight control computer. In a preferred embodiment, the flap assembly (30) includes a plurality of flaps (38a-38c) each coupled to the nose assembly frame (26) and an actuator that selectively positions the plurality of flaps (38a-38c) in response to a signal. The method for rotating a vehicle (10) in nose-forward flight, rotating the vehicle (10) in a first direction, and selectively actuating one of a first and second flaps (38a-38c) from a retracted position toward an extended position to generate a damping moment tending to position the vehicle (10) in a base-forward orientation.

摘要： An aluminum-alloy article such as a fastener or rivet (40) is prepared by providing an aluminum-alloy article precursor that is not in its final heat-treated state, and in one form is in its solution treated/annealed state. A curable organic coating material is also provided. The method includes anodizing the article precursor, preferably in chromic acid solution and without chemical sealing during anodizing, applying the organic coating material to the aluminum-alloy article precursor, and precipitation heat-treating the coated aluminum article precursor to its final heat-treated state, thereby simultaneously curing the organic coating. If the aluminum alloy temper is of the naturally aging type, it is optionally lightly deformed prior to precipitation treatment aging. The approach may also be applied to articles that are not solution treated/annealed and aged, by first overly deforming the article precursor so that the curing treatment of the coating also partially anneals the article precursor to the final desired deformation state.
