Abstract: METHOD FOR MOUNTING MICROSPHERE            COUPLING LENSES ON OPTICAL FIBERS                  Abstract of the Disclosure A microsphere bead coupling lens can be mounted onto an end of an optical fiber after the end is initially pre-pared by cleaning and cleavage.  An adhesive is first applied to the cleaved end.  The applied adhesive end of the optical fiber is then approximately centered over a microsphere bead to be mounted.  The fiber is lowered until the adhesive on the end contacts the bead.  The fiber is then raised whereby the adhesive on the end holds onto the bead by surface tension so that the bead gets picked up as the fiber is raised; and, due to the combination of surface tension and gravity, the bead lens is moved by the adhesive until the lens is aligned with, or very close to, the cen-tral axis of the fiber.  Subsequently, the adhesive on the fiber end is cured by means such as ultraviolet-curing or heat-curing.

Abstract: ADAPTIVE DIFFERENTIAL PSK DEMODULATOR   .    ABSTRACT   An adaptive differential phase shift keyed (PSK) signal demodulator which optimally tracks changes in the symbol rate of the signal.  An input signal is delayed by one symbol period by passing the signal through a charge coupled device (CCD) clocked by pulses phase locked to the symbol rate (Fbr) by a phase locked loop, the phase locked loop also outputting clock pulses at the symbol rate to strobe a symbol decision circuit.          The CCD has L stages and is clocked at a rate L.Fbr.  As the phase locked loop tracks changes in the symbol rate, the clock pulses are varied in rate so that the CCD delay is adaptively optimized for a given symbol rate.  Digital tuning is provided by an adjustable divider circuit coupling the voltage controlled oscillator of the phase locked loop to the CCD, so that by digitally selecting the division ratio the demodulator is tuned to a different symbol rate.

Abstract: INTEGRATED ENTRY/DISPLAY SYSTEM                  ABSTRACT OF THE DISCLOSURE A user touch input and output display system which combines elements of a capacitive attenuator type touch switch and a display into a single system.  In one embodiment type, one of the electrodes of the display per-forms double duty as a rear pad, for example a transmitter pad, of a capacitive attenuator type touch switch.  The other rear pad necessary for operation of a capacitive at-tenuator touch switch may either be within the same cham-ber or envelope as the display electrodes, or may be out-side the chamber.  The display may for example be a gas discharge display, and the shared electrode does double duty as the display anode and a touch switch transmitter pad.  Alternatively, the display may be a liquid crystal display.  In embodiments where the other rear pad is with-in the chamber, to avoid noise interference to the touch switch caused by the gaseous discharge, it is preferable to operate the system in a display mode and in a touch switch mode at different times.  During the touch switch mode, the display anode which also serves as the touch switch transmitter pad is supplied with an effectively AC signal.  During the display mode, the display anode may be supplied with either a pulsating or a steady DC voltage. In another embodiment type, a liquid crystal display is driven by an AC voltage source having a high series imped-ance, and a display elecrode is capacitively coupled to a touch pad.  When a user touches the pad, sufficient signal is shunted to ground to drop the voltage across the dis-play electrode below that necessary to maintain visible energization.

Abstract: Zenith Docket No. 4144 H?  Docket No. 973 ABSTRACT OF THE DISCLOSURE         In order to avoid spurious responses at the third harmonic of the signal frequency, a surface acoustic wave filter employs a multi-strip track coupler in which the spacing d of the elements is an integral multiple I of the acoustic wavelength .lambda. of the third harmonic.  When the condition d=I.lambda. is satisfied, the coupler blocks transmission of the third harmonic from the input transducer track to the output transducer track.  This basic principle can also be used to block other frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE A valve has features for wedging its gates into sealing contact and for balancing pressure exerted on the stem.  The valve has a body with a cavity.  A stem connected to a handle extends through the body into the cavity.  The stem moves a pair of gate segments between an open position and closed position.  A pressure balancing shaft is carried in a passage that is opposite the stem.  The shaft has an end stop that prevents further outward movement.  Both the shaft and the stem have wedging devices that wedge the gate segments apart from each other when the stem is in its lower position.  The stem has the same pressure area as the shaft to reduce torque requirements for opening and closing the valve.
