Abstract: ABSTRACT          The Apparatus and the method of the invention dyes the yarn ends of a sheet thereof individually at pre-determined positions along their lengths and manufactures tufted carpets therefrom in a tufting machine to provide a predetermined multi-colored complex pattern in the carpet.          The invention includes pretreatment of the yarn in a wetting and cleansing bath, removing excess bath liquid in prepara-tion for dyeing, synchronizing the yarn feed at the start with the feed to the tufting machine, simultaneous dyeing of pairs of adjacent yarn ends and separating them for delivery to the tufting machine in an arrangement to produce identic-al patterns side-by-side in the carpet.

Abstract: DEVICE FOR REPRODUCING THE CHARGE STORED IN AN INPUT CAPACITOR           IN A PLURALITY OF OUTPUT CAPACITORS     ABSTRACT OF THE DISCLOSURE         Arrangement allowing an input bucket brigade (BBD) stage to feed several other BBD stages in parallel with no loss of the signal transferred from the input stage to the subsequent ones.  An input voltage corresponding to a charge quantity is stored in the second capacitor of the input BBD stage.  The drain of the output transistor of the input stage is connected to a first BBD stage wherein the first capacitor is con-nected to the source electrode of the first transistor of a second BBD stage.  The first transistors of both stages are controlled by the same clock pulses.  When these transistors are turned on, the capacitors con-nected thereto are in series with the second capacitor of the input stage. Consequently, the same current will flow through these capacitors, which will thus store the same charges so that the charge representing the input voltage will be reproduced in the first capacitors of the two BBD stages connected to the input stage.  Means are provided for grounding the terminal of the first capacitor in the first stage that is connected to the source of the first transistor in the second stage at the time the transfer of the duplicated charge takes place.

Abstract: Abstract of the Disclosure In a train control signalling system, a wayside signal of an unknown code rate is detected and decoded on board the train to determine the code rate and derive the coded train control intelligence.  The code rate is deter-mined by counting the number of cycles of a known higher fre-quency which occur during one period of the unknown code rate. Before a train command signal is issued, a number of tests are performed to verify that the determination is accurate with no margin for error.  The known higher frequency signal is passed through a tuned circuit to verify that it is within predetermined limits of its rated frequency.  The counter that counts the cycles of the known higher frequency is tested to verify that it is reset to zero at required inter-vals.  Verification is obtained that one and only one train control signal is obtained.  The counting circuits and memory devices are cycled prior to each decoding operation to verify proper functioning.  Each train control circuit is tested and none can operate unless the prior one in the chain responded properly.  A train control circuit cannot remain operated un-less it receives periodic confirmation signals.

Abstract: PLOW               Abstract of the Disclosure A plow having a main frame beam disposed in a diagonal direction with respect to the direction of travel and having a plurality of plow bottoms equally spaced along the diagonal beam, each bottom being vertically pivotally supported on the beam.  A furrow wheel frame is carried on the rear of the beam to swing about a vertical axis.  The plow bottoms and wheel frame are connected together and are power operated so that the plows may have their effective plowing width adjusted while at the same time positioning the furrow wheel frame.  A hitch connection is carried on the forward end of the plow and is composed of a first part which is adapted for connection to a tractor and a second part which is rearward of the first part and adapted to shift with the plow frame.  The two parts are connected by a vertical pivot to permit relative lateral swinging between the parts.         Master and slave cylinders extend respectively between the first and second parts of the hitch and furrow wheel frame and the furrow wheel so that upon adjusting the width of cut of the plow bottoms on the go which would tend to shift the hitch parts relative to one another the position of the rear furrow wheel with respect to the wheel frame is automatically adjusted.  The master and slave cylinders are so mounted and dimensioned that the rear wheel will automatically adjust itself with respect to the direction of travel in order to achieve desired steering of the rear wheel and resultant positioning of the rear position of the frame.

Abstract: ABSTRACT OF THE DISCLOSURE     A data processing system in which the operating logic thereof is arranged to provide for an overlapping of the access, or "fetch" operations such that access to a second memory module can be obtained by a processor unit before a data transfer has been completed with respect to a first memory module and read-out of the second memory module can process during the rewrite cycle of the first module to reduce the overall processing time.  Such operation is made even more effective by arranging the system to utilize memory interleaving techniques.  Further, the system of the invention can provide for multiprocessor operation with a single memory system by the use of appropriate time-sharing techniques wherein processors can be operated in time-phased pairs, suitable multiprocessor control logic being arranged to provide for preselected priority allocations among the multiple processors to permit the most effective management of the multiprocessor system.
