Title: Thin Magnetic Film Memory.
IPC: G11C7/00
Filed: 1967-08-02
Abstract: 1,182,840. Magnetic storage elements. INTERNATIONAL BUSINESS MACHINES CORP. 2 Aug., 1967 [4 Aug., 1966], No. 35404/67. Heading H1T. [Also in Division H3] In order to write information into an anisotropic thin film microwave absorption memory of the type shown in Specification 1,182,839, a substantially hard axis magnetic field is applied along each column and a substantially easy axis magnetic field is applied along each row. The matrix, Fig. 1, comprises a plurality of continuous closed hard axis loop thin film structures 2 each enclosing a sense line 10 connected at one end to a microwave source 6 and a sense amplifier detector. In order to write information into the store a plurality of word drivers 20 are each connected to drive lines 22 arranged generally parallel to the hard axis of the films as shown and a plurality of driver circuits 26, which supply bit pulses of lesser intensity than the word drivers 20 are connected to bit lines 28 which extend generally parallel to the easy axis and are looped back. Each driver line 28, Fig. 2, comprises an upper leg 28a and a lower leg 28b each leg comprising a plurality of lands 36 in the shape of a parallelogram and the lands being interconnected by links 45, 46. In operation a bit current flowing from top to bottom is represented by a vector which has a component parallel to the easy and to the hard axis of the films and since the drive line is looped back upon itself the current now flows from the bottom of the figure to the top which current has a vector along the easy axis which cancels out that due to the current in the upper leg 28a and a vector along the hard axis which adds to that of the upper leg. The resultant of the current flowing in the bit line 28 is to provide a magnetic field along the easy axis. At the same time a current is passed through the appropriate word drawer line 22 which line is directed along the easy axis and hence a field is produced parallel to the hard axis. When the pulses cease the resultant magnetization of the film takes up one or the other of the positions along the easy axis determined by the binary digit stored therein.

[Class 87 (ii)] [Also in Groups VI, XII, XXIV and XXX] In the manufacture of bread or like cereal product as a continuous endless loaf a plurality of parallel troughs are formed on an endless chain conveyer extending through a' prover and baking oven by short lengths 13 of metal mounted on slats 6 connected across the chains, the lengths 13 being outwardly inclined and normally abutting edgewise but diverging apart at each end of the conveyer. A sheet of dough is fed from a hopper through feed rollers 16, 17 on to the conveyer, roller 16 being formed with discs or knives cutting the sheet into separate widths for each trough. The rollers are mounted on arms 19 oscillated about a fulcrum spindle 20 by discs 31 with offset crank pins 32, the discs being mounted on a countershaft 28 supported on the arms and the pins 32 on fixed slotted bearings, as a result the dough sheets being deposited in vertical sinuous folds in the troughs. The roller 17 is driven in timed relation with the conveyer from the countershaft 28 which is chain connected to sprockets 25 driven from the conveyer drive shaft 7, and the roller 16 is driven at equal speed from the roller 17 by spur gearing. Rams 34 mounted within the feed ends of the troughs are driven synchronously with the arms 19 from a rod 37 engaged in slotted brackets 41 depending from the arms, to press the folds of dough together. The rams 34 are hollow and have perforated faces with flared openings through which air under pressure passes continuously or during the compression stroke from a manifold 44 to prevent adhesion of the dough. The rams have terminal periods of dwell in forward and retracted positions. One or more endless bands 48 extending over part of the prover and/or oven and moving at conveyer speed may act as lids pressing upon the dough sections to square their shape. The baked loaves at the oven exit pass to a table or conveyer on which they are simultaneously and regulatably divided into sizes and/or sliced. The dough may be initially proved before feeding into the troughs and may alternatively be fed by hand or mechanically into the troughs in the form of balls subsequently allowed to unite.

Title: Light sensitive copysheets and methods of use thereof
IPC: G03G17/02
Filed: 1960-10-24
Abstract: 927,386. Producing photographs by light and electrolytic action. MINNESOTA MINING & MANUFACTURING CO. Oct. 24, 1960 [Oct. 23, 1959], No. 36457/60. Class 98 (2). [Also in Group XXXVI] An electrophotographic plate comprises a photo-conductive indium oxide coating on a contiguous electrically conducting backing. The indium oxide may be bonded to the electrically conductive base by means of a flexible film forming polymeric binders such as 30: 70 mol. ratio copolymer of butadiene and styrene, polystyrene, chlorinated rubber, rubber hydrochloride. The conductive backing may be aluminium, chromium, nickel or copper. Electrically conductive glass, paper or plastic can also be used as a backing or support. The weight ratio of oxide to binder ranges from about 4: 1 to 8: 1. Preferably a coating composition is made by ball milling an intimate mixture of indium oxide, the binder and a volatile solvent such as toluene and ethylene until a ratio i 30 /id of at least 2.5 where id is the dark current and i 30  the increase in photo current after a 30-second exposure to standard wet test conditions and the dark current. The currents id and i 30  are measured by coating an area of 1:13 cm.<SP>2</SP> of aluminium with a suspension, drying and measuring the dark current and the current under an intensity of 1300 foot candles at a P.D. of 9.25 volts in a solution of 1 molar (NH 4 ) SO 4 . Sensitizing dyes may be added to the indium oxide and these have the effect of increasing both the rate of response and the ratio <SP>I</SP> 30 / ld  of the indium oxide. The indium oxide film may be deposited directly on to a conductive backing without the binder. Thus a strip of Nesa glass may have part of its conductive surface removed and exposed to indium oxide vapour. Nesa glass each side of the deposit acts as an electrode. An electrophotographic sheet may be developed by electrolytic techniques using direct or alternating current and aqueous solutions of silver salts leuco dyes and nickel salts and indicator dyes such as Malachite green, Methyl red, Thymol blue and Alizarin red S. These developers may be incorporated or in the surface layer of indium oxide and developed in situ. They may be contained in a transparent layer such as gelatine, electrolysis being accomplished by passing a nickel bar connected as the anode and heated if desired over the fusible surface layer. It is preferred not to use additional developers, electrolytic reduction converting the indium oxide to indium metal. Any electrolyte, for example tap water, may be employed. The image may be erased by means of nitric acid. Specification 864,474 is referred to.
