Abstract: ABSTRACT OF THE DISCLOSURE A self-damping bellows seal assembly for providing a seal between a rotatable shaft and a stationary member through which the shaft extends.  The assembly includes a flexible bellows surrounding the shaft and secured at one end thereto.          An annular face seal is fixed and sealed to the other end of the bellows and is biased by the bellows into sealing engagement with the stationary member.  The means which secures and seals the face seal to the bellows includes a flexible member which closely surrounds the shaft.  This provides the advantage that the flexible member operates to dampen vibrations in the bellows.  The bellows seal assembly includes stamped sheet-metal parts and can be used when the assembly is to be secured to the stationary member and the face seal to engage a radial face on the shaft.

Abstract: R.J. Williamson -D.N.-Batcherlder 9-3 METHOD OF AND APPARATUS FOR FLOW MEASUREMENT                 ABSTRACT OF THE DISCLOSURE A vortex flowmeter measures flow velocity by detecting the eddies or vortices that are present in a moving fluid.  A light beam transmitted through the fluid from a source to a detector is refracted by the passage of the eddies therethrough.  This causes corresponding changes in the detected output.  By using a split detection arrangement, the velocity of the eddies and hence that of the bulk fluid is determined.  In an alternative arrangement, a single detector is employed, and the fluid velocity is determined from the rate at which the eddies pass through the light beam.

Abstract: METHOD AND APPARATUS FOR DRAINING LIQUID WORKING FLUID FROM TURBINE CANNISTER          OF A CLOSED CYCLE POWER PLANT         ABSTRACT       Liquid working fluid is drained from the sump of the cannister of a power plant of the type described by transferring the working fluid to the condenser rather than to the boiler.  In one embodiment of the invention, liquid in the sump is drained by gravity into an auxiliary boiler which heats the drained liquid producing vapor at substantially the pressure of the condenser; and the resultant vapor is piped directly into the condenser where it condenses and joins the main condensate produced from vapor that has been exhausted from the turbine.  In a second embodiment of the invention, the exhaust conduit carrying exhaust vapor from the cannister to the condenser is provided with a loop or elbow that extends below the level of the cannister,  and a conduit connects the sump in the cannister to the loop.  As a consequence, liquid working fluid in the cannister drains by gravity into the bottom of the loop where it is vaporized or swept by extracting superheat from the exhaust vapor and then returned to the condenser.  This arrangement is     advantageous in that no additional fuel is utilized to vaporize the drained    liquid.  Furthermore, the work required of the condenser is reduced because of the reduction in superheat of the vapor entering the condenser.

Abstract: ABSTRACT    Apparatus (10) for producing microform re-cords from hard copy or a cathode ray tube image or the like fed from a selected data source, in-cludes an image-reducing projection (20, 21, 22) system into which is selectively directed light reflected from hard copy or light from the face of a remote cathode ray tube (25) to which white background CRT image-forming signals are fed.  The reduced image involved is preferably applied first to a non-archival heat developable mask-forming film, like a dry silver film, and then the image on this film is transferred preferably to an ar-chival film capable of later receiving additional data on unused portions thereof and most advan-tageously arranged as a microfiche card.  A cath-ode ray tube (25) smaller than the hard copy is positioned below but in spaced relation to a hard copy receiving platform-containing (17) or receiv-ing image field area.  An image magnifying lens (28) system is interposed between the cathode ray tube face and image field area so that an enlarged image of the cathode ray tube face (25a), of about the same size as the hard copy, is focused in the same plane in said area as the hard copy would occupy if present on the platform (17).  When the cathode ray tube image is present, the platform (17), which is preferably white opaque, is moved away from the image area so that the light image thereon is directed up into the image-reducing (20, 21, 22) projection system.

Abstract: Abstract of the Disclosure A method for controlling the air-to-fuel ratio fed to an engine or other combustion device provides for periodically adjusting the air-to-fuel ratio to stoichiometric or near stoichiometric, within the response range of the conventional exhaust gas sensor employed.  This establishes a reference point from which the setting of an air-to-fuel ratio propor-tioning device (e.g., carburetor) is established by moving its adjustment means a selected distance from its setting at the reference point.  The selected value may be outside the normal response range of the sensor, either rich or lean of stoichio-metric.  The apparatus may include a sensor which generates an output signal which is compared against a reference signal by a comparator.  When the output signal exceeds (or falls below) the reference signal, a timer to operate the proportioning device adjustment means in the desired direction for a stated interval of time is actuated.  A separate timer operates the adjustment means towards stoichiometric at selected intervals to periodically establish the reference point.

Abstract: ABSTRACT A digital control system is provided to regulate the speed of a brushless DC motor via pulse-width modulation.  Digital counters are used to measure the difference between the time for a motor revolution and a reference time.  This time difference is in turn used to control the time until the application of power during a fixed period.  A motor speed decrease increases the difference in time between a motor revolution and the reference time.  This decreases the power pulse delay time and results in an increased power-on time to bring the motor back up to nominal speed.

Abstract: ABSTRACT OF THE DISCLOSURE A signal separation system is provided which includes a plurality of serially coupled signal transfer stages. A video information signal is applied to an input stage and is delayed by at least the time interval of one horizontal television line (1-H) as it passes through the stages.  Various ones of the stages which are 1-H apart in time include outputs, which are combined by weighting function and summing or difference circuits to produce bandwidth-limited transversal filter output signals.  These signals are additively and subtractively combined to produce a combed band passed chrominance signal and a fully restored and combed luminance signal, thereby obviating the need for subsequent filtering before the signals are further processed. The bandwidth-limited signals  may also be combined to provide a user adjustable peaking control signal for the luminance information channel.
