Abstract: FILTERS COMPRISING REACTIVE COMPONENTS, AND A METHOD OF DETERMINING IMPEDANCES THEREOF     Abstract of the Disclosure A filter comprising reactive components which define pass and stop bands has the impedances of the components selected to minimize the sum ?Zin-Z2? + ?Zout-Z1? in the pass band, where Zin and Zout are respectively the input and output impedances of the filter and Z1 and Z2 are nominal termination impedances at respectively the input and output of the filter.  The filter characteristic in the pass band is thereby made substantially independent of the actual termination impedances of the filter in use.  The design is exemplified by a 5th order low pass filter for connection in the voice signal path of a telephone subscriber line.                           -i-

Abstract: ABSTRACT          This invention relates to apparatus for auto-matically grading and sorting articles, especiallg 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: INVENTION:   MONITORING SYSTEM           INVENTOR:    ISAAC RAPOPORT            ABSTRACT OF THE DISCLOSURE          A method of detecting the presence of an object in a supervised area is described.  The method involves generating a pulsed ultrasonic signal with an acoustic signal generator, and directing the signal towards the supervised area. detector spaced a short distance from the generator is used to detect reflected signals produced in response to the ultrasonic signal, and a level signal indicative of the intensity of the detected signals is generated.  The level signal is compared with a threshold signal during a pre-determined time interval corresponding to the expected travel time range of signals reflected from the supervised area, and when the threshold signal is exceeded, a signal indicating the presence of an object is generated.  Cross-talk between signal generator and detector which might otherwise trigger an indicating signal is effectively eliminated by increasing the threshold signal during the predetermined time interval following each sound pulse to correspond to the expected magnitude of the cross-talk.  A detection system embodying the method is also described.

Abstract: Abstract of the Disclosure An improved method and apparatus for electro-photography in which a processing unit carrying a photoconductor drum, an exposure system, a liquid developer applicator, an excess liquid removal member, and a cleaning member is mounted for reciprocating movement with a forward stroke and a return stroke below a platen supporting the original document and in which drive means is provided for translating the unit and for rotating the drum in synchronism with the translatory movement of the unit.          A paper handling unit carrying a pair of registration rolls, a transfer corona, a copy paper pick-off, and a pair of delivery rolls, is mounted for reciprocating movement between a registration position at which its registration rolls receive a sheet from a supply of copy material and a position adjacent to the delivery end of the machine.  In operation, the processing unit moves from its home position toward the registration position as the initial part of the image of the original is formed and developed.  As it moves through the registration location, the processing unit picks up the paper handling unit and automatically provides a drive for the rollers thereof as the two units move together toward the delivery end of the machine.  As the leading edge of the copy reaches its terminal location in the tray, movement of the units reverses and the copy delivery operation is completed during this reverse movement, before the paper handling unit returns to the registration position.

Abstract: ABSTRACT OF THE DISCLOSURE           A procedure for classifying a crystal mixture or for concen-trating rocks or mixed crystals in particle form is provided herein.  The procedure involves capturing the particles in a gas flow for the purpose of separating particles of different size and weight by means of natural or artificial gravity.  The particles are heated to a temperature so high that a difference sufficient for separation is obtained in volume and/or weight between different particles.  For spodumene, quartz and feldspar this temperature is about 1000 C.  This is advantageous in that the pro-cedure can take place in a dry environment, the use of chemicals is avoided and grinding becomes simpler.
