Title: Memory Unit.
Inventor: FEDOROV ALEXEI SERGEEVICH
IPC: G11C11/06
Filed: 1967-08-23
Abstract: 1,167,824. Magnetic storage arrangements. INSTITUT TOCHNOI MEKHANIKI I VYCHISLITELNOI TEKHNIKI AN SSR. 23 Aug., 1967, No. 38851/67. Heading H3B. A magnetic storage matrix has the storage cores 1-12 associated with certain of the crossing points of the row and column lines X, Y as shown in Fig. 1, and each line is connected to a respective pulse transformer 13-18, 29-32 having input windings 19-21 and 33- 36 which are individual to the row pulse transformers 29-32 and are common to respective pairs of column pulse transformers 13-18, the column pulse transformers being provided with a common additional winding 28 which serves as a sense winding. The column pulse transformers have linear magnetization characteristics, whereas the row pulse transformers have rectangular characteristics and include a common restore winding 37 for restoring a row pulse transformer switched by an input pulse to its initial magnetic state. To read out a particular storage core, " O " driving half current pulses are coincidently induced in a row and a column line by selectively pulsing a transformer input winding 19-21 and 33-36 for each co-ordinate, the different conditions obtaining in the two column lines (e.g. Y 11 , Y 12 ) pulsed by a common input (e.g. 19) inducing an output in a sense winding 28 if an interrogated core is in the " 1 " state. To write a " 1 " in a read out location, coincident half current pulses of the reverse polarity to that used for reading are induced in the selected row and column lines by applying a reverse pulse to a linear column pulse transformer and a restore pulse to winding 37, the latter pulse restoring the rectangular characteristic row pulse transformer previously switched to its initial state. To write an " O," the reverse polarity and restore pulses applied to the two transformers, respectively, are made non- coincident. Noise is minimized by threading the sense winding in opposite respects through the two cores of each transformer pair, and by sequentially reversing the sense winding connections between successive pairs of transformers, as shown.

Title: Production of elemental sulphur and iron from iron sulphides
IPC: C22B1/02
Filed: 1968-08-14
Abstract: 1,224,247. Recovery of iron and sulphur. SHERRITT GORDON MINES Ltd. 14 Aug., 1968 [26 Aug., 1967], No. 38887/68. Heading C1A. Iron and sulphur are recovered from sulphides by: (a) treating a slurry of finely-divided pyrrhotitic mineral sulphides in aqueous media with a free-oxygen-containing gas at below 120 C.; (b) reacting the resultant slurry with sulphuric acid and sulphur dioxide to convert the oxidized compounds in the slurry to sulphates, and dissolve; (c) separating the solution from the residue; (d) heating the solution under oxidizing conditions to precipitate basic iron sulphate; and (e) recovering the precipitate. Pyritic sulphide may be converted to pyrrhotitic sulphide by heating, giving sulphur. Sulphur may also be recovered from the residue of step (c) by slurrying with water, heating to above the melting point of sulphur for a short time to form sulphur globules, cooling to form pellets, and screening. A surface-active agent, e.g. gum arabic or a sulphonated fatty acid ester may be added prior to heating. Occluded sulphides may be removed from the sulphur pellets by hot filtration, or by extracting the sulphur into an organic solvent. In step (b) preferably sufficient sulphur dioxide is provided to ensure that all 3-valent iron is converted to 2-valent, and sufficient H 2 SO 4  is preset to ensure that at least one gram atom of sulphur is available per gram ion of iron. More preferably, half a mole of sulphur dioxide is provided per gram ion of ferric iron, and enough sulphuric acid to give an S/Fe ratio of 1À0 :1 to 1.2 : 1. If the iron sulphide contains non-ferrous metal compounds, these are taken into solution in step (a), and they may be removed, just prior to step (d) by reacting with metallic iron and/or a sulphidizing agent, e.g. S, H 2 S, (NH 4 ) 2 S. The product basic iron sulphate may be pelletized and roasted, and the SO 2  recycled to step (b). The resulting calcinate may be reduced at above 820 C. to give metallic iron.

Title: Magnetic tape apparatus
IPC: B65H20/00
Filed: 1959-11-17
Abstract: 926,535. Feeding magnetic tapes. H. PAPST. Nov. 17, 1959 [Nov. 17, 1958], No. 38919/59. Class 40 (2). [Also in Group XXIV] The capstan drive is effected through one or more pairs of normally disengaged friction wheels which are brought into driving engagement by the pressure of the pinch roller on the capstan. Permanent deformation of the friction wheels caused by their continuous engagement pressure particularly while stationary for lengthy periods is thus precluded. Fig. 1 shows the capstan 3 mounted on a lever 4 and driven from the motor shaft 12 through friction wheels 10, 8, 5 or through friction wheels 6, 5 depending on the direction of drive required. This direction is determined by rocking to one or the other of its terminal positions, a lever 15, which through levers 11, 9, 7 brings either wheels 10, 8 or the wheel 6 into operative but non-engaging position. Tape drive is then initiated by energizing a magnet 2a which through a lever 1a moves the pinch roller downwards and through the pressure exerted thereby on the capstan 3 forces the operative friction wheels into driving engagement. In a further embodiment, Fig. 4 (not shown), catering only for one direction of tape drive, shafts carrying the pinch roller and capstan, respectively, are mounted for limited rocking movement about axes perpendicular to these shafts, to achieve the necessary engagement pressure of the motordrive shaft directly with the capstan drive wheel 5. Fast rewind or advance of the tape spools may be effected by selective insertion in the drive from the motor of further friction wheels. Specification 698,476 is referred to.
