Definitions

  • the design comprises some few squares or points situated within a given color zone (including the background) and corresponding to a particular color (different from all the other colors of the design) they are wholly colored and the color of the said given zone is not repeated after them, the reader considering the color of such points as having priority to momentarily prevail on the color of the zone which remains, so to speak, in the readers memory.
  • the draughtsman or designer who prepares the design on squared paper should theoritically color the different colored zones in a quite uniform manner, as if he were painting the fabric itself. But in order to save time he usually only indicates the various colors in a somewhat approximative manner leaving to the reader to correct the obvious deficiencies. Considering for instance a zone of squares which should be blue, it may happen that some squares'of this zone are only very lightly colored, or even sometimes quite uncolored more particularly in the central portion of the zone, beingunderstood that the reader will obviously consider these squaresas blue.
  • the background of'the'design is considered as acolored zone, and in each coloredzone of the design and in each horizontal row thereof the designer only colors the first square which will be met when reading in the row.
  • the work to be effected by the. designer is thus reduced to a minimum and he may take care to uniformly color these few squares without this entailing a noticeable loss of time.
  • inorder to effect the automatic reading-in of such a design there is interposed between the photo-electric means which scan the said design and the punching means which perforate the paper or card a logic circuit .which registers each signal from the photo-electric means and corresponding to a color other than that of the support of the design (generally white), and which transmits this same signal to the punching means for each successive square of the row being read-in as long as the said logic circuit does not receive from the photo-electric means another signal corresponding to another color different from that of the design support.
  • a logic circuit which registers each signal from the photo-electric means and corresponding to a color other than that of the support of the design (generally white), and which transmits this same signal to the punching means for each successive square of the row being read-in as long as the said logic circuit does not receive from the photo-electric means another signal corresponding to another color different from that of the design support.
  • the logic circuit above referred to may conveniently comprise for each color a flip-flop of the type known as J-K, i.e. having an auxiliary inlet which actuates the flip-flop when the latter is conditioned by the application of opposed voltages onto the main inlets thereof, this auxiliary inlet being adapted to receive the coincidence signals which are conventionally emitted by the reading-in photo-electric means in order that the color signal be only effective when the said means are centered with respect to the square being read-in.
  • gate circuits are inserted between the auxiliary inlets of the flip-flops and the outlet of. the coincidence signal emitter so as to block this signal when the photo-electric means detect the colorof the design support (white).
  • the invention further concerns an arrangement according to which when the design comprises in some colored zones (as for instance blue) small surfaces bearing a particular color (e.g. maroon points in a design having otherwise no maroon zone), the color of the zone in which these small surfaces appear need not be repeated in any row after the corresponding square or squares.
  • the particular color of the small surface is considered as having priority, which means that in the colored zone under consideration (blue for instance) when this particular color (maroon for instance) is detected, it automatically prevails momentarily on the color of the zone (blue) which however remains registered in the logic circuits of the reading machine and therefore re-app ears as soon as the photoelectricv means have passed the last square corresponding to the said particular color.
  • the designer is thusdispensed from having to repeat the main color (blue) after each small surface or point.
  • the signal of the photo-electric means which corresponds to this color is caused to act as the signal corresponding to the color of the support (white), i.e. to block the passage of the coincidence signal towards the flip-flops of the other or "normal colors, but in addition the outlet of the flip-flop of the prif ority color momentarily blocks gate circuits interposed in the outlets of the flip-flops of the normal colors. Since the condition of these latter flip-flops remains unchanged, as soon as the signal corresponding to the priority colors ceases, the said gate circuits are reopened and the signal of the normal color of the zone being read-in is again effective to actuate the perforating means.
  • FIG. 1 shows a weave design as it has been hitherto established in the prior art.
  • FIG. 2 illustrates a first embodiment of a simplified design according to the invention.
  • FIG. 3 shows how such a design may further be simplified.
  • FIG. 4 illustrates the diagram of logic circuits adapted to read-in a design according to FIGS. 2 or 3.
  • a conventional weave design on squared paper comprises a background I which is left uncolored (i.e. white in actual practice), being understood that in the reading-in operation any uncolored square exterior to the main colored zones of the design will correspond to the background weave.
  • the design further comprises a blue zone 2 having three dark points 3, and a red zone 4 surrounded by a green zone 4, the red zone also having three dark points 3.
  • the design is easily read-in in a perfect manner by the known photo-electric reading machines provided the logic circuits of the machine are so arranged as to select the background weave whenever the white color of the support is detected.
  • a first solution within the scope of the present invention consists in considering the background as a col-.
  • FIG. 2 illustrates the design which is thus obtained.
  • Such a design may be easily read-in by any competent reader and also by a photoelectric machine provided its logic circuits are so arranged as to consider a white" signal as an order to repeat the preceding color signal. Referring for instance to the horizontal row A-A (FIG.
  • the photo-electric means will detect a first square having the color (different from white) of the background and they will send a corresponding signal to the logic circuits which will transmit same to the perforating means (or to an intermediate register). Then the photoelectric means will detect four white squares and, in accordance with the instructions which have been provided in the logic circuits, the latter will emit four successive background signals.
  • the sixth square of the row is again colored as the first one and therefore the photo-electric means will again emit a background signal.
  • the logic circuits will thus transmit a sixth background signal.
  • the next two squares will be blue (colored zone 2) and will be read as such thereafter three white squares will cause three repetitions of the blue signal.
  • the photo-electric mean will read three blue squares and thereafter a background square. Four white successive squares will cause four repetitions of the background signal. A colored background square will then be met and thereafter the photo-electric means will detect six successive green squares (zone 5), then two red squares (zone 4), then again two green squares before reaching a background square, then six white squares which will cause six repetitions of the background signal, and finally they will detect a last background square at the end of the row.
  • FIG. 2 may still be further simplified by taking into account two remarks.
  • the photo-electric means have first detected a square having the color of the background, four white squares which have caused four repetiitons of the background signal, and a sixth square having the color of the background as the first one, which corresponds to a total of six background signals. But this sixth square could as well have been left uncolored, i.e. white the photo-electric means would have detected five white squares, the background signal would have been repeated a fifth time, and here again six background signals would have been transmitted. After the sixth square the photo-electric means would have detected a blue square and emitted a blue signal in spite of the lack of color of the sixth square or last square of the first background zone.
  • the dark points 3 (which may be comprised each of more than one square) are surrounded by squares having the color (blue for instance) of the zone in which such points are located.
  • this surrounding could be limited to the right-hand side of each point (i.e. to the first square of the blue zone after the point), but nevertheless this requires a particular care from the designer since such points, even if they correspond to more than one square, cannot be easily considered as zones. But in general these points are of a color which is not to be found in the other parts of the design.
  • Such a particular color may therefore be considered as having priority over the other or normal" colors (including the color of the background) and the logic circuits of the reading-in machine may be so arranged as to act according to the following instructions
  • the priority color momentarily inhibits the repetition of the preceding normal color, such repetition re-appearing for the next white or differently colored square.
  • FIG. 3 is obviously simplified in a considerable manner with respect to that of FIG. 1.
  • the work and time required from the designer are of course correspondingly reduced.
  • FIG. 4 illustrates a possible embodiment of logic circuits adapted to emit correct perforating signals when they receive the signals of photo-electric means reading-in the simplified design of FIG. 3 by successive horizontal rows.
  • each rectangular block corresponds to a flip-flop of the type known as J-K, i.e. to a bi-stable flip-flop having an auxiliary actuating inlet M in addition to its conventional or main inlets J and K.
  • the outlets a and b are always at different levels, i.e. if a is at the higher level (level 1), b is at the lower level (level 0), and viceversa.
  • the main inlets J and K are connected with each other through an inverterl.
  • the incoming color signal is applied to one of these inlets (inlet J in the example illustrated).
  • the auxiliary inlet M receives a particularsignal which permits the flip-flop to operate and to register the color signal.
  • a signal I is applied to inlet J (and therefore a signal 0 to inlet K) the flip-flop is merely conditioned, but it only sets when a'signal or pulse of level 1 is applied to the auxiliary inlet M.
  • the flip-flop When the flip-flop is set, its outlet a is at the higher level 1 and its outlet b at the lower level 0. If thereafter the incoming color signal disappears (logic level 0) the flip-flop only returns to the reset state (a at 0 and b at 1) when the actuating pulse is again applied to its auxiliary inlet M.
  • the diagram of FIG. 4 further uses conventional NAND gates, i.e. inverted AND gates.
  • NAND gates are electronic circuits which only emit an outlet of lower level (level 0) when all their inlets are at the higher level (level 1), any other combination of inlet levels (as for instance I-O, 0-1 0-0 in the case ofa twoinlet gate) havinG for its result an outlet at the higher level (level 1).
  • FIG. 4 The diagram of FIG. 4 is established in correspondence with the-design of FIG. 3. It is therefore provided for one background color F, three normal colors C1, C2, C3, a priority color P and the white color B of the squared paper. For each color other than B there is provided a flip-flop of the type above referred to, which has been designated by the reference F followed by the indication of the color.
  • the color signals from the photo-electric means have been referenced as the colors themselves. Apart from the white signal B, they are directly applied to the first main inlet J of the corresponding flip-flops and through the inverter I to the second main inlet K thereof.
  • the logic circuits of FIG. 4 further comprise a sixth inlet Co adapted to receive the coincidence signals or pulses emitted by the scanning device to which the photo-electric means are associated, each time the latter explore the center of a square.
  • a sixth inlet Co adapted to receive the coincidence signals or pulses emitted by the scanning device to which the photo-electric means are associated, each time the latter explore the center of a square.
  • this pulse Co is directly transmitted to the auxiliary inlet M of the flipflop FP which corresponds to the priority color and also to one of the two inlets of a NAND gate pl the outlet of which is connected through an inverter 1'1 with the auxiliary inlets M of the four flip-flops FF, FCl, FC2 and FC3 of the normal colors (including the background).
  • the signal B corresponding to the white color (uncolored paper) passes through an inverter lo and reaches one of the two inlets of a NAND gate p2 the other inlet of which is connected with the second main inlet K of flip-flop FP.
  • the outlet of gate p2 is itself connected with one inlet of a third NAND gate p3 the outlet of which is connected with the second inlet of the first NAND gate pl.
  • the second inlet of gate p3 is connected with the fixed contact r of a grounding switch T.
  • the first outlet a of flip-flop FF is directly connected I with the perforating means so as to transmit to same the signal Ps which corresponds to the priority color. It may also be provided to use the inverted signal E which appears at the second outlet b of this same flipflop, this solution being of interest in some cases.
  • each flip-flop FF, FCl, FC2, FC3 is appliedto the first inlet of an individual NAND gate p4 associated with this flip-flop.
  • the secondinlets of t hese four gates p4 are all connected with the outlet of a common NAND gate p5 having one inlet connected with the above-mentieoned contact r and the other one connected with the first outlet a of flip-hop Fl.
  • the outlet of tach gate p4 is applied to an individual inverter i2 and the outlet Fs, C1s,,C2s, C3s of this inverter forms the signal which is sent to the perforating circuits. Hwre again there may be profled for each color an inverted outlet FE, C 1 s, m, C3s which may conveniently be directly derived from the outlet of the corresponding NAND gate p4 upstream of inverter i2, as shown.
  • the photo-electric means detects the first square of a given row B-B (FIG. 3) of the design, i.e. the colored background square along the left side of the first background zone, the signal F is received by the main inlet J of flip-flop FF which is thus conditioned.
  • the signal Co is generated.
  • Gate p1 then receives two inlets at the lever 1 and it emits an outlet 0 which is inverted by inverter i1 to produce the level 1, the latter being applied to the auxiliary inlets of the four flip-flops FF, FCl, FC2, FC3. Since only FF has been previously conditioned, it sets while the other three remain unchanged. Its gate p4 receives two inlets 1 and it therefore generates an outlet 0 which is inverted by the corresponding inverter 12. The outlet Fs of the logic circuits is thus brought to level 1.
  • flip-flop FP has also remained unchanged since logic signal P has itself remained at level 0. i
  • Gate p3 therefore generates on its outlet the logic level 0. Under such conditions, even when the coincidence signal Co appears, gate pl emits an outlet at level 1 which is inverted by inverter i1 to produce the level 0 at all the auxiliary inlets M of the four flip-flops FF, FCl, FC2, FC3 which therefore remain unchanged in state.
  • the logic circuits still emit the outlet signal Fs at level 1, as if the second square of the row had been colored with the beckground color F, in spite of the fact that FF is no more conditioned.
  • flip-flop FF since now its main inlets J and K are respectively at levels 0 and 1, it resets under the action of the coincidence signal, its outlet a returns to level 0 and the corresponding outlet signal Fs also passes from level 1 to level 0 (i.e. disappears).
  • the photo-electric means would thereafter detect ten successive white squares and as above explained for the background color F, the outlet signal of the logic circuits, Cls in the present case, would be maintained.
  • the photo-electric means would then reach in row 3-8 a square having the color F of the background. It will be easily understood that signal F would condition FF which would set when receiving coincidence signal Co, while FCl would reset. The logic circuits would emit the outlet signal Fs.
  • the ninth square of row BB corresponds to a point of the priority color P.
  • the photo-electric means detect such a square, they generate the corresponding signal P (or in logic terms this signal rises from 0 to 1).
  • This conditions the particular flip-flop FP which sets as soon as its auxiliary inlet M receives the coincidence signal Co. Its outlet a rises from level 0 to level 1 and therefore the logic circuits emit the corresponding outlet signal Ps.
  • the second main inlet K of flip-flop FB is at level 0
  • the outlet of p2 is at level 1 and therefore the outlet of p3 is at level 0 (since its higher inlet is to be considered as at level I).
  • the outlet of pl is thus at level I, whatever may be the level of Co.
  • the flip-flop FP corresponding to the priority color is the only one to which the coincidence signal or pulse Co is directly transmitted.
  • this signal or pulse Co is inhibited by either the white (signal B) or the priority color (signal P) in such manner that the flip-flops of the normal colors F, C1, C2, C3 are then locked.
  • the white signal B has no influence whatever on the outlets of the flip-flops corresponding to the normal colors F, C1, C2, C3, but on the contrary the signal P of. the priority color blocks these outlets and prevents the flip-flop which had been previously set from acting on the perforating circuits.
  • Gates p3 and p5 then receive logic signal level 0 on one of their inlets and they continuously generate on their outlets logic level 1.
  • the coincidence signal Co is thus always transmitted to the normal color flip-flops the outlets of which are never inhibited by the priority color. In such a case the background would be wholly white and the white signal B would be applied to flip-flop FF in lieu of signal F (in other words signals B and F would become identical).
  • any NAND gate combined woth an inverter could be replaced by a single conventional AND gate. This applies directly to the unit pl-i1. But if the inverted outlets FE, C 1 s, (is, 3 are left aside, each pair p4-i2 may also be replaced by an AND gate.
  • the flip-flops which have been supposed as of the J-K type, they could be formed each of a quite conventional flip-flop associated with an AND gate disposed upstream of its inlet and adapted to be conditioned by the Co signal.
  • each color zone including the additional one formed by said background, and in each row the marginal portion of said each zone which is met first when beginning the scanning of said each row and when passing from one of said color zones to anotherone of same.
  • a method as claimed in claim 1 for the preparation of a design comprising at least one small surface corresponding to a particular color different from that of said color zones, including the one formed by said background, and different also from the color of said support, with said small surface being situated within one of said color zones, which consists in wholly coloring said small surface and in leaving of the color of said support the first portion of said last-named one of said color zones which is met after said small surface when scanning a row intersection said small surface, the color of said small surface being considered as having momentarily priority over the color of said one of said one until said small surface is passed.
