A digital electric memory arrangement comprises rows and columns of memory modules 40 1 -40 4 , 41 1 -41 4 , each module comprising a matrix array of information storage addresses, interrogated on a coincident current basis, the modules being formed in groups 40, 41, 42, 43 arranged so that no group contains more than one module from the same row or column of modules, and a plurality of readout means with sets of readout means associated with each group and taking signals only from corresponding positions in the modules of any one group. As described the storage addresses comprise a matrix of individual cores 12 operable by currents on wires 44, 45 to switch and cause an interrogation pulse to be generated. The modules in each group are situated along diagonals, groups 40, 43 along the diagonals of the memory shown, group 42 along the remaining diagonals of the second and fourth quadrants and group 43 along the remaining diagonals of the first and third quadrants. A permanent magnet memory (Fig. 2) comprises a ceramic plate 10 associated with each column of cores, and having wrapped therearound a plurality of electrical. strip solenoids 11 1 , 11 2 , 11 3  . . . each inductively coupled at one end to a core 12. On each side of the plate 10 is a permalloy sheet acting as a return path for the magnetic field produced by the energization of the solenoids. The solenoids are inductively coupled to pluralities of wire memory elements 13a on one side of the plate and 13b on the other side each connected to a return electrical conductor 14. The wire elements comprise an electrical conductor having a helically wrapped covering of magnetic tape of magnetic material which has a substantially rectangular hysteresis characteristic. The wires 13, 14 associated with any one bit position in a word in a module pass through the same bit position in all words of the module and are coupled to a primary transformer winding (50, Fig. 5, not shown) which is coupled to the corresponding wires 13, 14 of the other modules belonging to the same group.

Abstract: 1,107,394. Knitting yarns. R. H. MARKS. 24 May, 1965 [1 June, 1964; 23 Nov., 1964], No. 21853/65. Headings D1C, D1K and D1W. Substandard fibrous material is fed together with strands of a reinforcing material to the needles of a knitting machine whereby the strand is caused during the knitting action to surround or partially surround the fibrous material to form a core yarn so as produce a cheap knitted fabric. In one example the fibrous material, which may take the form of cotton motes is fed on to a layer of paper 9, Fig. 1, to which it is bonded and agglutinated by an adhesive from a trough 16 being spread over it as the two layers pass between rollers 17, 18 and thereafter heavy rollers 19, 20. The bonded material is then slit into strands 23 which are fed at the feeders of the knitting machine whereby a core yarn is produced during the knitting of the fabric. Alternatively the fibrous material may be bonded and fed separately from the paper web. The two webs are then individually slit and the strands combined at the feeders of the machine to be fed together to the needles to form the core yarn and fabric. If desired the fibrous material strands may be reinforced by yarns fed from bobbins on the machine.
