Abstract: A turbine of a turbocharger includes a floating insert which defines a nozzle for passing a fluid and which is supported axially slidable with respect to a housing by a sliding support. Furthermore, the turbine comprises a sealing member for preventing a flow of fluid between the floating insert and the housing. The sealing member is axially expandable and has a fixed end attached to the turbine housing and an opposite movable end attached to the floating insert.

Abstract: An exemplary bearing and locating pin system for a turbocharger includes a locating pin including a shaft, a head and an aperture and a bearing having a central axis and including an internal bore to receive a shaft extending between a compressor wheel and a turbine wheel, the internal bore including a plurality of axial grooves, the bearing including a locating pin aperture substantially equidistant from axial ends of the bearing for engaging the locating pin to prevent rotation of the bearing within a bearing case bore, the bearing further including a plurality of lubricant inlets, each inlet extending between an outer surface of the bearing and one of the axial grooves at an angle non-orthogonal to the central axis. Other exemplary technologies are also disclosed.

Abstract: An exemplary bearing assembly for a turbocharger includes a center housing with a bearing bore having a bearing bore turbine end radius and an inlet for lubricant and a unitary bearing disposed in the bearing bore and forming an outer lubricant film between the bearing and the bearing bore wherein the bearing includes a central axis, an internal bore to receive a shaft extending between a compressor end and a turbine end of the bearing and forming an inner lubricant film between the internal bore and the shaft, a locating mechanism between axial ends of the bearing to prevent rotation and translation of the bearing within the bearing bore and a turbine end protrusion wherein the protrusion comprises a radius that exceeds the bearing bore turbine end radius to thereby deflect lubricant from the outer lubricant film layer radially outward. Other exemplary technologies are also disclosed.

Abstract: A landfill (10) having a leachate collection apparatus including a layer of geonet material (40) disposed above a liner (38) as its primary leachate flow path. Leachate flows along the geonet material to a collection trench (16) located along an edge (14) of a generally planar landfill area (12). The superior hydraulic conductivity of the geonet material (34) disposed above a liner (32) is provided below the primary drainage layer for additional ground water protection. A collection box 918) having both a leachate collection compartment (54) and a leakage collection compartment (56) is disposed in alignment with openings (80, 82) formed in the respective liner layers. The sealing surfaces (64,68) between the collection box and liners are all located on upper surfaces of the collection box.

Abstract: A collapsible `bedspring` monopole antenna is configured to be effectively non-observable in its collapsed condition and, when deployed, remains sufficiently compact to ensure very low observability characteristics, while providing broadband coverage over a wide viewing aperture. The antenna is comprised of a conductor formed as a tapered helix. One end of the conductor is coupled to an antenna feed. The outer end of the helix is looped around on itself to form a circular loop. A plurality of substantially rectilinear `radials` are soldered to distributed locations around its circular loop, so as to extend outwardly and tangentially from the outer perimeter of the loop and provide `top hat` capacitive matching elements. To define the height of the deployed antenna and to electrically short out plural locations of the helix, a plurality of conductive straps are joined to respective spaced apart locations of the helix.

Abstract: In a time division multiple access satellite communications system having a master station and one or more remote stations, frequency offset through the translation oscillator in the satellite is corrected by transmitting a pilot frequency signal, reference to a high precision oscillator, through the satellite, so as to subject the pilot frequency signal to a frequency translation and monitoring the frequency translation of the pilot frequency signal as received at the master station subsequent to its transmission through the satellite. Signals to be transmitted over the satellite communications link from the master station to remote stations are subjected to a frequency translation that is effectively complementary to the monitored frequency translation.

Abstract: Method of formation of lenses at optical fiber ends to increase the coupling efficiency thereof. In a first embodiment, the end of the optical fiber is masked with a substance non-soluble in the etching reagent. The portion of the coating at the very end of the fiber is then removed and the fiber end immersed in an etching reagent. The etching reagent serves to dissolve the uncoated portion of the fiber. By controlling the amount of time that the fiber end is in the reagent, different lens shapes may be formed. In a second embodiment, the fiber end is dipped into a liquid epoxy compound whereby a portion of the epoxy is deposited onto the fiber end. The surface tension of the portion deposited thereon draws the liquid epoxy into the desired lens shape. The epoxy is then hardened to form a permanent lens structure on the fiber end.

Abstract: A low distortion modulated light source, including a light emitting diode and a compensating diode. These diodes are arranged in parallel for D.C. biasing, and in anti-series with respect to the A.C. signal path. Means are provided for varying the relative biasing of the two devices so as to thereby adjust the A.C. characteristics of the compensating diode to more accurately correspond to the A.C. characteristics of the light emitting diode.When properly biased, the inherently non-linear junction capacitance of the light emitting diode is compensated so as to substantially eliminate undesired harmonics and intermodulation products.
