899,367. Circuits employing bi-stable magnetic elements. AMP Inc. Jan. 30, 1961 [Feb. 17, 1960], No. 3391/61. Addition to 899,366. Class 40 (9). In a shift register as described in the parent Specification, in which advance windings 100, 101, Figs. 2 and 3, transfer windings 58 and priming windings 102 are associated with magnetic storage cores 18 each having a main aperture 62, a transmit aperture 60 and an optional receive aperture 52, the cores are mounted vertically in slots in an insulating panel 12, Fig. 1, so as to form two interleaved columns 14, 16 with respective core apertures in alignment, one column comprising the evennumbered " E " shift register core stages and the other the odd-numbered " O " core stages. As described in the prior Specification, the flux in a core is either wholly in one direction about the main aperture or has a portion encircling the transmit aperture for denoting a zero or a one storage state respectively. The advance winding 101 is a mirror image of winding 100, and with two of the transfer windings has been omitted from Fig. 2 which shows an input winding 50 passed through the receive aperture of the first core stage and connected to terminals 54, 56 on the insulating panel. Other panel terminals 24 and 42, 28 and 46, and 26 and 44 provide connections to the two advance windings 100, 101 and the priming winding 102 respectively. The terminals 42, 44, 46 are linked if a complete shift register is mounted on one panel, otherwise they are used to provide separate connections to terminals 24, 26, 28 of a further panel. Terminals 68 and 70 are also provided for an output winding (not shown) passed through the transmit aperture of the last stage. The cores are held in position by insulating strips 20 which are glued to the panel and pass through the main apertures, and insulating pins 30-40 are mounted on the panel at various points to provide supports for intermediate reversals of direction of the advance and priming conductors during winding. The cores are wired as shown schematically in Fig. 3, a reference such as 62 " O " denoting that a portion of a winding passes through the apertures 62 of all the odd-numbered cores, while the number of complete loops of the winding portion represents the number of winding turns. The physical layout of the various windings is described with reference to Figs. 4 to 9 (not shown), both advance windings, one portion of the priming winding, and the transfer windings coupling the transmit apertures of the odd cores with the main apertures of even cores being arranged on one panel face, while the even to odd core coupling windings, the input and output windings and the remainder of the priming winding are arranged on the reverse face. |
