Abstract: DUAL BELT PULP WASHER                 ABSTRACT OF THE INVENTION     A machine and process for washing paper stock pulp and similar free-filtering materials includes two or more horizontally-disposed wash drums (11) mounted each in a tank (45).  Two endless filter belts (83 and 85) are trained to pass under each of said wash drums (11) and through liquid contained in each of the tanks (45).          A mat of pulp (102) is formed between the two endless filter belts (83 and 85) and carried under each of the wash drums (11) for washing therein.  Wash liquor passes through the pulp mat (102) as it travels under each of the drums (11) thereby washing the pulp mat, and the liquor passes between the drums (11) and the tanks (45 and 47) by gravity flow.  After the pulp has been washed it is removed from between the two belts (83 and 85).

Abstract: ABSTRACT          This invention relates to apparatus for auto-matically grading and sorting articles, especially fruit, according to size, surface blemish and surface color. Prior art automatic processes have resulted in incomplete grading and are incapable of providing certain important information such as abrupt variations of blemishes and size related information.  The present invention provides an improved apparatus and method for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color.  Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments,  Significant differ-ences between such measured intensities are detected and a measurement of surface blemish is generated in accor-dance therewith.  Size measurements are derived by count-ing the total number of segments in the surface of each fruit,  Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit.  The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a system including a compact array of microphones in combination with signal combining circuitry, especially suited for use with surround-sound sources, for producing two composite signals LT and RT corres-ponding to those required by an SQ-matrix-type quadraphonic system to establish the directional position of the sound sources.  The signals pro-duced by selected ones of the microphones are combined to produce an auxiliary signal which contains, to the extent they are present, equal proportions of signals corresponding to the signals LF, RF, LB and RB of the SQ quadraphonic system which exhibit an equal angular relationship respecting corresponding signals in a composite signal representing the sum of LT and RT.  The auxiliary signal enables decoding of the directional signals in the 4-3-4 or the 0-3-4 modes.

Abstract: ABSTRACT OF THE DISCLOSURE           A triple function image processing system incor-porating, for operation in a first COPY mode, a light/lens imaging system for imaging originals at a viewing station or platen to produce latent electrostatic images thereof on a photoconductive surface.   The electrostatic images are developed and transferred to a copy substrate material as in conventional xerographic systems.  A flying spot light beam is provided in a second WRITE mode, the flying spot beam  writing  images  on  the photoconductive  surface  in response to image signals input thereto.  In this mode of operation, the beam impinges on the photoconductive surface at a location upstream of the developing device.  And, in a third READ mode, the beam is impinged on the photoconduc-tive surface downstream of the developing device to scan images  developed  on  the  photoconductive  surface.   The scattered light is collected and converted to image signals representative of the image scanned.          In an alternate embodiment, the flying spot beam impinges on the photoreceptor at a single location upstream of the developing device for both WRITE and READ modes.  To preserve the developed image for scanning by the flying spot beam in the READ mode, the developing device and the image transfer and cleaning mechanisms are disabled until after the developed image has been scanned.
