Definitions

  • a device for making digit winding loops in memory storage matrices comprises a memory plane frame having cores threaded with coordinate wires lying in both directions, needles at the leading ends of the wire for wiring a digit winding, and a surface plate temporarily fastened to the frame and having also attached thereto at least one movable strip disposed along the row of oppositely lying loops, the surface plate and the movable strips having openings arranged so as to correspond to the position of the digit winding loops in I the matrix; the device is also provided with clamps fixing the movable strips in place, and detachable connectors the number of which is equal to that of the loops in the matrix.
  • the present invention relates generally to the an of making ferrite core stores for electronic computers, logic switching units control, communication and monitoring circuits and more particularly, it relates to devices for making digit winding loops in memory storage matrices.
  • the invention can be used for manufacturing ferrite core matrices with any arrangement of cores at the intersections of the X and Y wires in the matrix and ferrite cubes made in the form of mats, strands and frameless storage units of practically unlimited capacity assembled from cores of any dimensions, including superminiature cores, and employing any topological pattern of digit winding arrangement, including diagonal arrangement.
  • a device for making digit winding loops in memory storage matrices which comprises a memory plane frame with cores threaded with X and Ycoordinate wires, and a needle at the leading end of the wire intended for threading the digit winding. Loops of the digit winding are made by hand, the size of the loop, its position and curvature radius depending on the accuracy of the eye and skill of the operator.
  • This device has the disadvantage of not being provided with any means for arranging and forming the digit winding and, especially, its loops in the matrix. This results in a low quality of matrices, makes the threading operation depend on operators individual abilities, reduces the efficiency of the laborer, calls for high operators skill and exerts considerable strain on 3 his eyes.
  • Another known device for threading ferrite core matrices with X, Y and digit wires employs manual formation of digit winding loops.
  • This device comprises a vibrator and a special jig which is an apertured plate, the size and the shape of the apertures repeating those of the core.
  • the apertures are disposed against the matrix cores at an angle of 45 with respect to the axes of the rows of cores.
  • the jig has an adhesive-coated side so that each aperture becomes a socket with an adhesivecoated bottom for retaining a core.
  • the jig is placed over the cores with its adhesive-coated bottom outside and the cores, when shaken by the vibrator, adhere to the bottoms of the sockets.
  • This device permits of stringing a digit wire through the cores adhesively attached to the plate before threading X and Y coordinate windings, which facilitates the preparation of loops of digit windings. Further, the cores fixed in the sockets along the edges of the matrix allow for visually monitoring the size of the digit winding loops.
  • This known device has also several disadvantages.
  • Second, the jigs employed in the device are expensive and difficult to manufacture. For superminiature cores, fabrication of such jigs becomes absolutely unfeasible.
  • Threading of the cores rigidly fixed in the jig sockets creates considerable stresses on the cores, which tends to break the cores and increase the amount of discarded matrix planes.
  • removal of the adhesive layer and detachment of the jig from the threaded matrix also involve core damage.
  • It is an object of the present invention is to provide a device for making digit winding loops in memory storage matrices which will be simple and convenient, enable identical loops to be made in the digit winding halves regardless of the operators skill, and permit of minimizing the strain on the operators eyes.
  • the essence of the invention resides in that the device for making digit winding loops in memory storage matrices, comprising a frame having cores threaded with X and Y coordinate wires and needles at the leading ends of the wire for threading a digit winding.
  • the device further comprises a surface plate disposed parallel to the matrix plane and temporarily fastened to the frame which has at least one movable strip attached to the frame along a row of opposite lying loops, the surface plate and the strips having a plurality of openings against the digit winding loops in the matrix circuitry, the device being also provided with strip clamps and detachable connectors the number of which equals to that of loops in the matrix, the diameter of the loops corresponding to the inner diameter of the loop curvatures and to the diameter of openings in the surface plate and the movable strips.
  • the proposed device makes it possible to simplify the labor-consuming operation of making digit winding loops and can be used for threading matrices composed of toroidal ferrite cores of any size arranged in any to- 5 pological pattern and for wiring high-quality digit windings of practically any known topology.
  • a device for making digit winding loops in memory storage matrices comprises a frame 1 of a matrix 2 carrying coordinate wires 3 lying in one direction with cores 4 threaded with coordinate wires 5, lying in another direction, and with a digit winding 6.
  • a wire 6' for making the digit winding 6 terminates in a needle 7 to facilitate threading.
  • a surface slate 8 is rigidly attached temporarily to the frame 1 of the matrix 2 for a period of time required to thread the digit winding 6.
  • At least one movable strip 9 is mounted on the surface plate 8 for a row 10 of oppositely lying loops ll of the digit winding 6, or a plurality of movable strips 9 is disposed thereon, depending on the number of the rows 10 of the loops 11.
  • the surface plate 8 and the movable strips 9 fastened thereto by means of clamps 12 have openings 13 for detachable connectors 14 which are arranged strictly against each loop 11 in the matrix 2.
  • the diameter of the detachable connectors 14 corresponds to the inner diameter of the curvature of the loops ll of the digit winding 6 and to the openings 13 in the surface plate 8 and the movable strips 9.
  • the connectors 14 freely enter the openings 13 so that a minimum gap is left.
  • the surface plate 8 with the movable strips 9 fastened thereto is fixed, with the aid of the clamps 9, to the frame 1 of the matrix 2.
  • the ends of the wires 3 in one direction, preliminarily strung through the cores 4, are attached to the frame

  • the wire 6' of the digit winding 6 is passed through the cores 4 strung on these two wires 5 in accordance with the topology of the matrix 2, and before pulling these wires tight, two detachable connectors 14 are inserted into the openings 13 of the surface plate 8 corresponding to the loops 11 in the center of the matrix 2, and the first pair of the loops 11 of the digit windings 6 is made around these connectors.
  • next detachable connectors 14 are inserted into the openings 13 on the attached strips 9 in places where the loops 11 are formed at the edges of the matrix 2.
