Filed: 1991-03-07
Abstract: METHOD AND APPARATUS FOR AUTORANGING, QUADRATURE  SIGNAL GENERATION, DIGITAL PHASE REFERENCE  AND CALIBRATION IN A HIGH SPEED RF MEASUREMENT RECEIVER            ABSTRACT           Improved autoranging, calibration, and a complex signal detection circuits for an intermediate frequency (IF) stage in a radio frequency (RF) measurement receiver (8).  An improved autoranging circuit (75) sets a gain stage of a selectively variable gain amplifier (72) prior to each data acquisition cycle, to provide for wide-dynamic range and rapid time domain response.  An improved complex signal detection circuit (80) for generating an inphase (i) and quadrature phase (Q) signal from an input IF signal in a signal channel (38a) and a reference channel (38b) is constructed with a novel commutating demodulator circuit (12a, 12b).  Calibration is effected with an improved digital phase reference method and apparatus wherein effective 90° phase shifts are digitally generated by shifting the generation sequence of timing signals for the complex signal detection circuit (80) instead of phase shifting a known calibration signal, obviating the need for precision phase shifters, Dopler frequency generators, or Fourier transforms to obtain correction components for the optimum detection of complex signals.

Title: Interstage thermal shield retention system
Inventor: NARAYANA ANAND D
IPC: F01D5/08
Filed: 1992-09-09
Abstract: Docket No. 13DV-10806 Abstract An interstage thermal shield assembly for a gas turbine engine.  The assembly includes an axially-extending thermal shield positioned between first and second stage disks to form a seal therebetween.  The thermal shield includes complementary hook members shaped to engage slotted hook members formed on the first stage disk to form a bayonet connection, and complementary lip members for engaging lobe members formed on the second stage disk by means of split rings, thereby eliminating the need for a bolted connection between the thermal shield and disks and facilitating attachment and removal of the thermal shield.  The thermal shield includes an annular impeller which is positioned rearwardly of the first stage disk, the impeller including bayonet connection with the disk which restrains the impeller from axial deflection, but permits radial deflection in response to thermal changes.  The thermal shield also includes an annular bore, attached to and extending radially inwardly from the thermal shield, and rotating in a plane substantially normal to a rotational axis of the shaft mounting the disks.  The bore is shaped to have a center of mass out of the plane of rotation, so that rotation of the bore creates a moment  which urges the bore to deflect toward the upstream disk, thereby compensating for a pressure differential across the face of the bore as cooling air is pumped by the impeller radially outwardly toward the end of the first stage disk.

Title: Vehicle lighting system
Inventor: LU TAN T
IPC: H05B39/10
Filed: 1992-10-29
Abstract: ABSTRACT OF THE DISCLOSURE A lighting circuit for a vehicle illuminates a back-up lighting element when a primary lighting clement fails. Both lighting elements may be installed in a single housing, such as a headlight assembly. A dashboard switch places the primary lighting element in circuit with the vehicle power supply. Inpreferred form, a low-resistance coil is series connected with the primary lighting element. The coil is magnetically coupled to switching elements in a low-current flow path between power supply terminals. Switching elements in the low-current flow path control a low-power mechanical switch that places the back-up lighting element in circuit with the power supply. If the primary element fails, the absence of current through the coil triggers the switching elements to close the mechanical switch and to illuminate the back-up element. The dashboard carries a graphic representation of the vehicle. A light emitting diode on the representation is illuminated when the primary element fails to indicate the location of the failed element.
