Definitions

  • a MADcore shift register similar to the one described in the aforesaid patent application, is provided with additional toroidal magnetic cores inserted in the ⁇ respective coupling loops of the register. These additional cores, which are relatively inexpensive,
  • FIGURE of the accompanying drawing is a schematic circuit of a shift register embodying features of the invention.
  • the shift register 1t shown odd numbered (O) core 11 and an even numbered (E) core 12, each of which is made of magnetic ferrite material.
  • Core 11 has a central aperture 13 which is coupled by an advance O drive winding 14.
  • core 12 has a central aperture 16 whichis coupled by an advance E winding 18.
  • O core llr has a minor output or transmitting aperture20 which is threaded by a cou-V pling loop 22, this loop also threading a minor input aperture 24 ⁇ of E core 12.
  • In the Ysame Way core 12 has an output aperture 26 which is threaded by a coupling pointed out in the following description.y
  • Threading output apertures 20 and 26 is a prime Winding 30.
