Abstract: VECTOR PINNING IN AN ELECTROPHOTOGRAPHIC MACHINE                 Abstract of the Disclosure Apparatus and method for pinning the value of a white, gray or otherwise colored, single-shaded vector in an electrophotographic machine.  The vector is the value of the image voltage minus the developer voltage.  Valuation of changes in the image voltage are obtained by 1) sensing the reflectivity of a developed single-shaded image and converting that into a representative voltage; 2) sensing the reflectivity of the bare photoconductor and converting that into a repre-sentative voltage; 3) obtaining a measure of the difference between the representative image and reference voltages; and 4) noting changes in the difference.  Pinning the vector calls for adjusting the developer voltage or document illumina-tion intensity level an amount necessary to compensate for the change in image voltage.

Abstract: SIMULCAST TRANSMISSION SYSTEM HAVING   PHASE-LOCKED REMOTE TRANSMITTERS                        ABSTRACT      A simulcast transmission system is provided where a reference signal transmitted from a central station is utilized to phase-lock transmitters located at remote stations.  The remote stations include a receiver for receiving the transmitted reference signal and a signal conditioner for conditioning the received reference signal for application to the transmitters.  The transmitters include a phase-locked loop which may be followed by a multiplier for providing transmitter signals of predeter-mined frequencies. All the transmitters at the remote stations are phase locked to the reference signal trans-mitted from the central station.  In the event that the reference signal transmitted by the central station is interrupted, the signal conditioner of the remote stations will operate in an open-loop fashion to provide the conditioned reference signal during the interruption.  After the inter-ruption has cleared, the signal conditioner is automatically phase synchronized to the reference signal and closed-loop operation is resumed.

Abstract: ABSTRACT OF THE DISCLOSURE A recursive noise reduction system for a television system uses the spatial corelation in a frame difference signal derived by element-by-element subtraction of an incoming video signal from corresponding picture elements of a relatively noise-free stored video signal to reduce noise in a video signal.  The spatial corelation is used to suppress the com-ponents of the frame difference signal which are due to frame-to-frame changes in the video resulting from motion in the scene, thus producing a signal which contains sub-stantially only the noise in the incoming video.  The noise signal thus derived is subtracted from the incoming video signal to produce a noise-reduced output signal for display or recording.  The noise-reduced output signal and the incoming video are added together in varying proportions according to the amount of scene-to-scene motion detected and the sum is stored for use in subsequent treatment of new incoming video.

Abstract: ABSTRACT OF THE DISCLOSURE          A vane shape for producing optimum washing action in vertical axis clothes washing machines including vanes located in the bottom of the tub or basket and shaped with radially canted edges which cause the fabric articles to be pulled and said outwardly as the edge is rotated into the articles to establish a toroidal circulation within the tub.          In a preferred embodiment, an oscillated agitator is provided with a series of vane pairs joined at the lower side to form a V-shaped trough with either upper edge of the vane pairs inclined to produce a net outward movement of the washed arti-cles by alternate engagement with a respective upper edge of either vane blades upon alternate rotation into the load.          The vane shapes are either mounted to an oscillating agitator, a rotary impeller, or integrally formed in an oscillating basket.  An arrangement for attenuating the action of the vane shapes is provided either by movable intermediate spoil-er vanes or the combination of a reduced size vane agitator is used for gentle wash loads, with a slip-over agitator having vanes of normal size.  Variations in the vane arrange-ment include asymmetrically sized vane pairs which balance torque variations in the agitator drive mechanism, and a snap-in lint filter occupying the space between vane pairs; additional radially extending vanes which augment the circu-lating effect by drawing the clothing articles downwardly along the agitator post and into engagement with the vane shapes; and a vane shape for agitators which simplifies mold-ing of the agitator.
