Definitions
- This invention relates to an improved and simplified wiring arrangement and layout for a shift register employing magnetic cores.
- An object of this invention is to provide a shift register which can be more easily wired on a mass production basis than comparable units previously known.
- a similar object is to provide a shift register which can be manufactured in less time and at lower cost than previously known registers.
- a further object is to provide a register of this kind which can be wired with less chance of error, and which will operate with a higher degree of reliability than previously known units.
- the cores are in the forms of toroids with a large central aperture and with additional minor apertures at various points around the body of the toroid. These cores are about the size of a small shirt button and the minor apertures are not much larger than the size of a needle. Accordingly, a considerable problem is presented in passing the necessary wires through the various ones of the apertures of the cores.
- the present invention among other things provides a simplified wiring arrangement which nonetheless gives the improved electrical performance of units disclosed and claimed in the aforesaid co-pending application.
- three sets of windings two comprising advance windings to be energized by short electric pulses, and a prime winding to be energized by direct current, or by a suitable current pulse, are separately wound upon the cores, each Winding being a continuous strand threaded back and forth in a unique pattern through respective apertures of the cores to establish the required turns ratios for the winding on the cores.
- the invention makes it possible for a person in assembling the shift register to thread each of these windings in accordance with its predetermined pattern back and forth Without having to make splices or electrical connections at various points in the Winding. Consequently, the wiring of the unit is con- 2 siderably simplified and since the number of electrical splices which must be made is reduced, the reliability of the unit is improved and the danger of error in manufacture is considerably reduced.
- the various windings are terminated at each end of the unit on posts arranged so that the output of one unit can be connected to the input of an identical unit, and so on, to give a shift register of twice, three times, etc., the length of the original.
- a basic shift register assembly of say 10 bits it is possible simply by connecting two or more such units in series to obtain as many bits in a given shift register as desired.
- the electrical connections between basic units are quickly and easily made so that only a single basic one need be manufactured to supply the needs of many difierent customers.
- FIGURE 1 is a perspective view of a shift register embodying the invention and showing its actual physical appearance
- FIGURE 2 is a schematic diagram showing several cores of the unit of FIGURE 1 and various windings thereon;
- FIGURE 3 is a schematic diagram showing in shorthand fashion the wiring configuration of various windings with respect to the various apertures of the cores of the unit; and i I FIGURES 4 through 9 show respectively the winding sequences and configurations of various windings on the cores and illustrate a preferred procedure followed during the mass production of these shift register units.
- the shift register 10 shown in FIGURE 1 includes an insulating base board 12 on which are mounted two parallel and somewhat interleaved columns 14 and 16 of multi-aperture cores 18.
- Column 14 will be designated the 0 (odd numbered) cores and column 16 the E (even numbered) cores.
- Each core is mounted on edge and projects through a corresponding transverse slot in board 12.
- Each column of cores is aligned and held in place by a respective one of the flat insulating strips 20 and 22 glued to board 12 and passing through the center or major apertures of the cores.
- unit 10 At the near or input end of unit 10 are three upstanding electrical terminal posts 24, 26 and 28 rigidly fixed to board 12. As will appear, these posts comprise the input connections to the unit for various drive currents supplied from an external power source (not shown) during operation of the unit. Immediately behind these electrical posts are three insulating pins 30, 32 and 34 which serve to support the near ends of the drive windings on the cores. A similar set of insulating pins 36, 38 and 40 is positioned at the far end of the core assembly, and near the rear edge of board 12 are three conductive posts 42, 44 and 46. The latter are normally shorted together by a conductor 48.
- an identical shift register unit as indicated by dotted lines can be connected in series with unit 10 by removing conductor 48 and by connecting output posts 42, 44 and 46 to respective ones of the input posts, corresponding to input posts 24, 26 and 28, of the next unit. Also, as will be explained shortly, the signal output of unit 10 would be connected to the signal input of the next unit.
- FIGURE 2 is a schematic circuit representation of the cores and windings of unit 10. Counting the cores from left to right, the first core 18 is designated an core and has an input signal winding 50 passing through a minor aperture 52 of the core and, as seen also in FIG- URE 1, terminating at conductive posts 54 and 56.
- An input signal winding 50 passing through a minor aperture 52 of the core and, as seen also in FIG- URE 1, terminating at conductive posts 54 and 56.
- signal winding 58 passing twice through a second or output minor aperture 60 of the core and encircling once the second core 18, an E core, through its major aperture 62.
- the latter core is similarly coupled through its output minor aperture 60 to the third core by a signal Winding (not shown), and so on to the end of the register.
- signal winding 58 passes through the major aperture of the receiving core, an input minor aperture in this core being shown but not used.
- the circuit shown in FIGURE 2 includes a first drive winding, designated ADV O to E whose input end is connected to terminal 24 and which is adapted to receive a negative current pulse of relatively short duration.
- This winding as indicated also in FIGURE 3, encircles in the same sense, each 0 core four turns and each E core one turn through their major apertures. The other end of the winding is connected to terminal 42.
- a second winding, ADV E to 0, extends from terminal 28 and encircles each E core four turns and each 0 core one turn, the other end of the winding ending at terminal 46.
- the cores are threaded with a Prime winding, extending between terminals 26 and 44, and which encircles with one turn, in opposite sense from the advance windings, each major aperture of the cores, and with three turns each output minor aperture.
- the relative Winding senses of the advance and prime wind ings are indicated by the arrows in FIGURE 3.
- the Prime winding is common to a portion of the advance windings and is independently energized, as indicated in FIGURE 3, by a battery in series with an isolating induetor.
- the single 0 and E Major turn of the prime winding cancels one turn of the four turn 0 portion of the ADV O to E winding between terminals 24 and 42 and the entire single E turn portion.
- the net ADVO to E winding constitutes three turns thnough the major apertures of the 0 cores.
- the net ADV E to O winding constitutes three turns through the major apertures of the E cores.
- this winding arrangement simplifies the layout'of the advance and prime windings and makes possible the easy interconnection of two or more units in sequence.
- FIGURE 4 The physical wiring pattern of the ADV O to E winding is shown in FIGURE 4. This winding, on the top side of board, extends from terminal 24 and makes four turns through the major aperture of the 0 cores, one turn through the E cores, and six turns on the outside and is then connected to terminal 42.
- the ADV E to O winding, as shown in FIGURE 5 is the mirror image of this.
- FIGURE 6 the Prime winding near the major apertures of the E cores, one turn outside of the cores, and'ends at terminal 44.
- FIGURE 8 is a top View of board 12 and shows inpu winding 50 and those of the signal windings 58 which extend from the O to the E cores. Also shown is an output signal winding 66 which encircles twice the minor output aperture of the last E core and is connected to terminals 68 and 70 (see also FIGURE 1).
- FIGURE 9 which is a bottom view of board 12, shows the signal windings 58 extending from the E to the 0 cores. The first 0 core has an auxiliary input winding 72 encircling its major aperture and the last E core has an auxiliary output winding 74 passing twice through its minor output aperture.
- windings can be connected together by suitable jumpers, not shown.
- output winding 74 of the first unit is connected to the input winding of the second corresponding to Winding 72.
- each core had a diameter of about A inch and a body about inch thick in each direction. They were made by General Ceramics Corporation of Keasbey, New Jersey and identified as 5209-FG96 material.
- An improved shift register comprising two parallel columns of magnetic cores each having a central aperture and at least one minor aperture, said apertures of the cores in each respective column being aligned with each other, a plurality of windings disposed on said cores, said windings including a first advance winding looped in one direction a plurality of times through the major apertures of the cores of one column, and looped once in said direction through the major apertures of the cores of the other column, a second advance winding disposed on said cores symmetrically with the first, a prime winding looped a plurality of times in the same sense through the minor apertures of said cores and also looped once in a direction opposite to said one direction through the major apertures of said cores, three input terminals connected to the inputs of said windings at one end of said columns, and three output terminals connected to the other ends of said windings at the opposite end of said columns, said output terminals comprising intermediate connections for said windings whereby said register can be used by
