946,280. Magnetic storage apparatus. AMP Inc. Oct. 30, 1962 [Nov. 21, 1961], No. 40918/62. Heading H3B. A shifting register as described in Specifications 894,025 and 899,366 is constructed by adhering multi-aperture magnetic storage cores 26-29, Fig. 4, to a correspondingly-apertured length of flexible tape 15 of non-magnetic insulating material and folding the tape as shown in Figs. 5 and 6, the folding operation forming the cores 26, 27 and 28, 29 into two columns with each core separated from its neighbours by a layer of tape. Prior to folding the tape, the minor apertures of the cores are threaded by input and output windings 16, 17, Fig. 2B, and by transfer windings 23, 24, 25, 25<SP>1</SP>, arranged so that adjacent cores in respective columns are coupled when the tape is folded. The assembly is compressed after folding, and the columns of cores threaded by copper rods 4, 6 which constitute the advance and priming windings and also serve to maintain the bores in alignment. As shown in Fig. 1, the copper rods engage notches 3 and holes 5 in fibre glass end plates 1, 2 and are secured by epoxy or phenolic cement, the end plates themselves being secured to a side plate 8 of the same material. Both side and end plates carry terminals 18, 19, 21 for the various windings, and the end plates in addition have printed circuit conductors 20 which connect the ends of the copper rods so as to form windings through the main and minor apertures of the cores. |
