Definitions

  • the invention is applicable for manufacturing ferritecore matrices having any arrangement for the cores at the matrix wire intersections and the memory modules made in the form of mats, bunches and frameless storage units of practically unlimited capacity, which may be assembled from cores of any size, including superminiature cores, and also from other ferrite storing elements.
  • the prior art device for making memory storage matrices comprises a frame with the two terminal plates thereof having terminals for attaching the ends of the Y axis drive wires threaded through the cores. These wires are laid with uniform spacing on a positioning roll with respect to a means for threading X axis drive wires and which are attached to the terminals with a slight tension.
  • the positioning roll has a longitudinal slot milled therein which serves for gripping one core on each Y A drive wire at a time and aligning the cores in a row.
  • the positioning roll On its end surface, the positioning roll carries a mechanism for the spiral curling of the wire used for threading the cores along the X-axis at a pitch equal to the spacing between the core centres on the positioning roll.
  • the device permits the monitoring of the electrical characteristics of the cores being threaded and eliminating for faults in the matrices in the course of the threading operation.
  • This device has a number of disadvantages.
  • the tension applied to the Y drive wires due to the elastic strain of the wires themselves requires that the device be carefully handled in operation. Any accidental touch loosens the wire tension allowing the cores thereby to slide down the wire from the threading area; besides, a stretched wire has to be replaced to preclude a defect in the matrix.
  • a wire fastened at two points can very easily be broken.
  • contact jumpers More over, for checking the electrical characteristics of the cores during threading, contact jumpers have to be provided between each pair of the y drive wires on one terminal plate. These contact jumpers are usually made by soldering adjacent terminals, and an extra soldering joint in the check circuit lowers the reliability of monitoring.
  • a disadvantage common to said known devices is the non-uniform wire tensioning due to a difference in the spring characteristics and the necessity to solder the wires to the spring in order to secure requisite contact for checking the electrical characteristics of the cores.
  • the Y drive wires inserted through the array of cores are fastened by hand to the terminal of the matrix terminal plate with slight tension being obtained as a result of twisting the ends of the wires around the terminals.
  • the X drive wires are strung through the cores by a freely suspended needle soldered to the end of the stringing wire while orienting the cores as required from below the matrix plane.
  • the manual threading operation has a disadvantage in that a constant wire tension cannot be maintained, due to which the connection of the wires to the plate terminals must be repeatedly readjusted.
  • a device for making memory storage matrices comprising Y axis drive wires strung through cores, a terminal plate to which the ends of the Y drive wires are connected via terminals thereon, and the means for threading the memory storage matrices with X axis drive wires, has a wire tension device with individual weights for each pair of Y drive wires, each of which weight taking the form of a plate having a thickness equal to twice the spacing between the Y drive wires and having a recess disposed in the proximity of the upper edge of the weight which accommodates a pulley gripping the middle of the Y drive wire, and with cores being strung on both ends of this wire.
  • This device makes it possible to increase the supply of core-stringing wires, considerably improves the uniformity of wire tensioning and provides for a more reliable checking of the electrical characteristics of the rows of the cores during threading.
  • the device can be successfully used for threading matrices assembled from other storage elements, such as biaxes, transfluxors, cyclops, etc.
  • a device for making memory storage matrices comprises a terminal plate I for the Y axis drive wires 2 strung through cores 3, with terminals 4 thereof serving for connecting the ends of the wires 2, one wire to each terminal 4.
  • the same terminals 4 can also be used for the connection of a tester for checking the electrical characteristics of the cores 3 (the tester is not shown).
  • the Y drive wires 2 curve around a means 5 for threading a matrix 6 with X drive wires 7.
  • the device also includes a means 8 for applying tension to the Y drive wires, individual weights 9 being provided for each pair of the Y wires.
  • Each weight 9 is made in the form of a plate having a thickness equal to twice the spacing between the two adjacent Y drive wires and has a recess 10 in proximity to the upper edge of the weight 9 which receives a pulley ll gripping the middle of the wire with cores strung on both ends of the wire. the length of the wire with being equal to that of the two Y drive wires 2.
  • the end of the wire intended for the Y axis drive winding is strung through the cores 3 the number'thereof being sufficient for an entire matrix or memory module. Then, the cores 3, in a number required for two Y drive wires 2, are separated from the rest of the cores 3 at the wire end, and a wire length is equal to the length of two Y drive wires and is then cut off. The cores 3 on the wire length are divided into two groups and the wire be tween the two groups is bent in two, thus forming a wire loop.
  • the loop is fitted onto the pulley 11 in the recess of the weight 9, whereupon both ends of the wire are connected to the respective terminals 4 of the terminal plate 1 for the Y axis drive wires.
  • the cores 3 of both Y drive wires 2 are placed in position for the threading means 5, and the wires are arranged parallel to each other in respective slots of the matrix threading means 5.
  • the next pair of the Y axis drive wires and all the subsequent pairs are handled and fastened in the device in a similar manner. Thereafter, the threading of the matrix 6 with the X axis drive wires 7 can be started in a fashion similar to any of the known threading methods.
  • pulley is used to denote a stationary wheel with a wire-gripping groove in its rim.
  • the weight 9 secures stabilize and optimumize the wire tension which improves the performance of the device as a whole.
  • each weight having upper and lower edges and a thickness equal to twice the spacing of said terminal means on said terminal plate, a recess being provided in proximity to said upper edge of each weight, and a pully being disposed in each recess, whereby each Y axis drive wire can be looped around the pully in a respective weight to form an adjacent pair of wires in the matrix and thereby pulled taut by the weight; and a means for threading the memory storage matrix with X axis drive wires.
