Abstract: OPTICAL COMMUNICATION ARRANGEMENT     Abstract of the Disclosure An optical transmission system includes a transmitter which transmits an electrical analog input signal as two separate optical signals through an optical transmission medium to a receiver.  Combining the two optical signals, the receiver generates an electrical analog output signal representative of the input signal, whereby harmonic frequency components which may have been introduced in transmission are absent.

Abstract: ABSTRACT OF THE DISCLOSURE         A matrix extractor is described which is particularly useful for extracting data from a memory which contains re-presentations of optically scanned characters.  The method and apparatus of the present invention permits the isolation of packets of data in the memory and the determination of the location of these packets.  Data representing the packets is then extracted from the memory for character recognition.  The isolation of packets in memory greatly reduces the amount of data which must be processed by the recognition processor and provides much more reliable recognition.

Abstract: Abstract A stepper for use between a transducer subjected to variable  pressure,  heat  or  liquid  level  for converting the continuous  output  signal  of the transducer with all of its variations, both of significant magnitude and those of insigni-ficant importance, into a continuous stepped output signal that increases or decreases the current to a transducer responsive control  unit,  particularly  a servo amplifier,  which stepped signal eliminates all minor and unimportant fluctuations from the  output  current  from  the  transducer.  The  stepper  also includes a sequence of voltage regulators  such as potentio-meters  in  the  circuits  between  the  stepper  and  the  servo amplifier by means of which the magnitude of the current flow of  each  step  to  the  servo  amplifier  may  be  adjusted  or programmed with respect  to one  another.

Abstract: ABSTRACT OF THE APPLICATION           In a television receiver with a digital signal processing system, circuitry is provided for establishing an analog output signal derived from the digital signal processing system at a predetermined level.  Digital samples representative of image information are coupled to a digital-to-analog converter which in response develops a corresponding analog output signal.  A driver circuit responsive to the analog output signal develops the appropriate drive signal, to generate a display of the image information.  A signal generator develops a control signal that is applied to the digital-to-analog converter to establish the analog output signal at a predetermined level.  In one embodiment, the control signal is a color kill signal which when active, eliminates the color component from the display, producing a monochrome image.

Abstract: ABSTRACT OF THE DISCLOSURE          The device comprises a casing composed of a bottom tray having an upstanding pivot post and a hinged cover having an open window.  Three concentric flat rings have partial designs embossed thereon to provide raised design portions, the inner ring being rotatable about the post, the intermediate ring rotatable about the inner ring and the outer ring rotatable about the intermediate ring.  By individually rotating or angularly positioning the rings relative to each other, any of the partial designs can be radially aligned to form a composite design.  After the composite design has been formed, a piece of paper is placed over at least the segments constituting the preselected design.  Closing of the cover on the tray clamps the rings in a fixed relation with each other so that the user can then rub a marking implement, such as a colored pencil or crayon, over the portion of the paper appearing in the open window in order to transfer the preselected design onto the overlying paper.

Abstract: ABSTRACT      METHOD FOR EXPOSING MINERALS IN OPEN-CUT MINING      The present invention relates to a method for exposing minerals in open-cut mining with the aid of a stacker which transports the layer of overburden, removed by excavators in one or more stages, over the open-cut and stacks it directly and at least one excavator-unit which dumps directly on the plane of the stacker or on a lower plane.  A pre-requisite for satisfactory operation of this method is to be able to allow the co-operating machines to work independently of each other.  Hence the purpose upon which the invention is based is to provide a method of excavating which reduces to a minimum the loss of time and productivity arising as the pieces of equipment pass each other, thus considerably improving the economics of the mining method.  In order to accomplish this purpose, it is proposed that when a stacker meets an excavator-unit travelling on the same plane, the excavator-unit shall proceed into an area behind the stacker to allow the latter to pass, which can be accomplished, if necessary, by means of a brief change in the directions of travel of the pieces of equipment.

Abstract: ABSTRACT OF THE DISCLOSURE     An anti-buckling control system is disclosed for articulated vehicles, especially articulated busses.  Two double acting piston-cylinder units are interposed in the pivot connection between the forward and followillg vehicular units for applying resistance forces against hinged or buckling movement of the vehicular units with respect to one another.  A computerized control unit is provided for controlling the hydraulic circuit for the piston-cylinder units so that they apply resistance forces tending to direct the buckling angle towards desired values determined in dependence upon the forward vehicular unit steering angle, the instantaneous buckling angle, and the vehicle velocity.  The piston-cylinder units are disposed with their ends at one vehicle side closely adjacent one another and with their ends at the other vehicle side spaced from one another to form a V-shaped configuration.          To increase the effectiveness of the piston-cylinder units for large buckling angles and the like, the ends thereof connected to a pivotal cross piece for supporting the following vehicle section, are disposed at the following vehicle side of the buckling pivot axis during straight driving conditions.
