Abstract: ABSTRACT OF THE DISCLOSURE           A multi-mode reproducing apparatus having an improved system for positioning the viewing and projection elements therein for purposes of moving original exposure.  Variable magnification copying is provided by holding a scanning mirror system in a fixed position to view a document which is advanced past its viewing domain. A system for repositioning the mirrors for conjugate change in accordance with one embodiment includes a device for uncoupling one of the mirrors from the drive system through the use of a selectively actuable stop mechanism and a quick-connect and disconnect type of coupling between the drive system and the mirror. In accordance with an alternative embodiment a friction clutch and selectively actuable atop mechanism allows one mirror to be stopped while another one continues to be driven to its stop position. when the mirrors are returned to their home position their original coordinated arrangement is restored.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a machine for inserting seed and fertilizer into the ground.  The machine comprises a frame, a storage tank, and a plurality of hoeing shares supported by the frame when the machine is in operation.  The hoeing shares are adapted to move individually, in a vertical plane, by means of holding devices, and the shares are arranged in at least three rows spaced one behind the other.  The hoeing shares are further provided with laterally spaced cutting surfaces which converge forwardly and form an acute angle of attack in relation to the surface of the ground, as seen in the operating direction.          Seed and fertilizer is fed to the said hoeing shares, from the relevant storage tank, in adjustable quantities, by a metering mechanism and through pipelines.  The attachment parts on the frame, for the holding devices, have a large ground clearance.          In accordance with the invention, the holding devices for the hoeing shares each comprise a parallel guide in a vertical plane, so that the acute angle of attack of the cutting surfaces of the hoeing shares, in relation to the surface of the ground, remains unchanged when the shares are moved in a vertical plane, the shares being also equipped with guide elements maintaining their depth in the ground.

Abstract: ELECTROCHROMIC DISPLAY DEVICE          Abstract of the Disclosure The invention relates to an electrochromic display device having a transparent container containing an indication electrode, a counter-electrode and an electrochromic solution contacting the electrodes.  The improvement is that the counter-electrode is provided with a coating of a reduction product of the color displaying ions or an oxidation product of the color displaying ions of the electrochromic solution.  By means of forming the coating of a color displaying product, when a current flows across the indication electrodes and counter-electrodes, the same redox reaction takes place at both electrodes but the reactions proceed in opposite directions.  As a result, the redox reaction can be caused to proceed with a voltage lower than the redox potential of the reaction and hence, electrode contamination by additional electrolytic reaction products can be avoided thereby pro-longing the life of the device.

Abstract: ENGINE SPARK TIMING SYSTEM WITH KNOCK RETARD AND WIDE OPEN THROTTLE ADVANCE          Abstract of the Disclosure In a spark ignition internal combustion engine with power output controlled by a throttle, a throttle switch provides a wide open throttle signal and a knock sensor provides a knock level signal.  A normal spark pulse train, corrected for intake manifold vacuum, engine speed and dwell angle, is fed through a shift register which delays each spark pulse by a fixed number of counts.  A pulse train generator responsive to crankshaft rotation produces a crankshaft reference angle pulse each fixed number of degrees of crank-shaft rotation; and these pulses are counted by the shift register to provide a normal spark timing.  First and second up-down counters are responsive to the knock detector, the first up-down counter counting up with excessive knock and being effective to delay the counting of the shift register by a period proportional to its count, the second up-down counter being responsive to the wide open throttle switch to count downward with excessive knock and insert extra pulses between the pulses of the pulse train generator in number proportional to its count to advance spark from the normal setting.

Abstract: GAS TABLE                 ABSTRACT OF THE DISCLOSURE             A method is disclosed for moving an object which is floatable on a cushion of gas from a first station to a second station.  A porous table over which the object is moved is divided into a plurality of zones of gas f low. Contiguous gas zones can have the same amount of gas flowing therethrough thereby to define areas of gas flow.  The areas of gas flow are never larger than the object being moved thereover.  The areas of gas flow have different amounts of gas flow with the largest occuring at the first station and the lowest at the second station.  When an object is placed at the first station, it is supported on areas having two different amounts of gas flow.  This causes the object to tip front end downwardly in the area of lowest gas flow and thereby be moved over the porous table member eventually to the second station.  The specification also teaches a method for moving an object from any one of a plurality of first stations to a single second station.

Abstract: PCM CODEC USING COMMON D/A CONVERTER       FOR ENCODING AND DECODING                           Abstract A codec (coder/decoder), having particular utility in a pulse code modulation (PCM) communications system employing per-line coding and decoding, employs a common digital-to-analog (DAC) converter.  A PCM signal to be reconstructed is decoded at two points of time within the basic sampling interval, preferably at twice the basic sampling frequency.        In order to realize the desired analog reconstruction level, the PCM signal is first decoded at a first decision level lying on one side of the desired reconstruction level; then modified and again decoded at a different decision level lying on the other side of the desired reconstruction level.          The average of the two decoded analog signals then lies on the desired reconstruction level.  In a conventional PCM system, the two PCM samples differ by only one least signi-ficant bit (LSB) in the PCM word used in setting the common DAC.  In a preferred embodiment of the invention, separate storage registers are respectively employed for the encoding and decoding, together with a selector for switching between the two registers during the two desired decoding intervals.          In this way, the encoding operation may be carried on during a substantial portion of the basic sampling cycle, being interrupted only for generation of decoded samples.  The invention is applicable to PCM systems generally t including compressed pulse code modulation (CPCM) systems operating in accordance with the U-law or the A-law.
