Abstract: 1486956 Magnetic bubble data storage INTERNATIONAL BUSINESS MACHINES CORP 17 March 1975 [27 March 1974] 10955/75 Heading H3B Security of data in a bit-organized multiple propagation path-per-word bubble domain memory is effected by inhibiting 26, 32 the propagation of domains in one or more paths 14 for a predetermined number of cycles. As shown, a 64-bit word is entered in parallel at 20 into 64 major/minor loop chips 12 and is propagated around the major loops 14 once by an in plane field H before transfer to appropriate minor loops 16 by a transfer conductor 18 as detailed in Fig. 2. A further conductor loop 26, having encircling "nodes" 30 at sizes operative when the field H is oriented in direction 1, is energized under a code key to prevent propagation of bubbles to poles 2 in selected chips, thereby encoding the data by mixing bit elements from different data words. The encoding is reversed by inhibiting propagation in the same loops 14 to restore synchronism before a read-out cycle. The code key includes a prefix to identify the chips to be effected and a suffix for the number of inhibit cycles.

Title: Improvements in and relating to the control of direct current electric traction motors
IPC: B60L7/04
Filed: 1936-04-17
Abstract: 473,367. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., BINNEY, E. A., and MARDIS, P. L. April 17, 1936, No. 11102. [Class 38 (iii)] Non-regenerative braking.-Electric traction equipment with provision for rheostatic braking comprises a D.C. motor of the augmented series field type, means such as contactors 9 for connecting the motor to a supply external to the vehicle for running, means such as tapping switches 6 or variable diverting resistances for varying the strength of the series field 2 during running, means such as a contactor 11 for connecting the armature 1 in a closed circuit for rheostatic braking, and means for applying to the motor, during such braking, a controllable excitation independent of the armature current. In the arrangement shown in Fig. 1, the independent excitation is obtained from a weak auxiliary field winding 3 with a series regulating resistance 7, which can be connected across the supply by closing a contactor 10. This winding can be used both for starting and for rheostatic braking, the motor being accelerated by cutting out the resistance 4 step-by-step by contactors 5, and subsequently cutting out the auxiliary field winding 3, and weakening the series field 2 by closing the contactor 6. For rheostatic braking, the contactors 9 are opened, and contactors 10 and 11 are closed, thereby disconnecting the armature from the supply and connecting it in series with the whole or part of the starting resistance 4. The field excitation may be strengthened as the motor slows down by cutting out the resistance 7 in one or more steps. An automatic strengthening of the field may be obtained by including a portion of the series field winding in the braking circuit or by including a portion of the resistance 4 in both the braking and auxiliary field circuits, Fig. 2 (not shown). In another arrangement, Fig. 3, the auxiliary field is dispensed with, and the series field is divided into two portions 2a, 2b, of which 2b may be included in the braking circuit, while the other and preferably larger portion 2a is excited from an auxiliary source of power 17 through a regulating resistance 19 for braking purposes. In another arrangement, Fig. 4 (not shown), the auxiliary source of power is connected across the whole of the series field for providing the excitation on braking, and a common resistance is included in both the armature and field circuits for automatically increasing the excitation as the armature current falls.

Abstract: 579,246. Hydrogen. BRITISH NON-FERROUS METALS RESEARCH ASSOCIATION, SMITH, E. M. D., BAKER, W. A., and LIDDIARD, E. A. G. July 8, 1943, No. 11120. [Class 90] [Also in Group II] Hydrogen is obtained by alloying or mixing magnesium with iron,.copper or nickel, or mixing magnesium with a salt or oxide of such metal, and bringing such alloy or mixture into contact with water which may be rendered conductive by the addition of a salt or salts in solution. The comminuted ingredients of the mixture may be compressed or worked into pellets or the like. The mixture may also contain a soluble, non-hygroscopic chloride, such as ammonium chloride to increase the reaction rate if relatively pure water is employed. Suitable alloys contain 15 per cent. copper and 85 per cent. magnesium or 20 per cent. nickel and 80 per cent. magnesium The alloying of iron with magnesium must be assisted by the introduction of a further alloying element, e.g., silicon. A preferred mixture is powdered magnesium with powdered iron or iron oxide, with or without ammonium chloride. The hydrogen may be produced in a generator of the acetylene type. Alternatively, a cylinder with an open bottom, a grid or construction for supporting the pellets and a controlled outlet for the gas may be employed. This generator is immersed in water, the level of which falls in the cylinder to below the level of the grid when the gas outlet is closed.

Abstract: 1, 040, 311. Paper; paper-making; web-coating apparatus. KIMBERLY-CLARK CORPORATION. March 25, 1963, No. 11708/63. Headings D1L, D2A and D2B. An aqueous solution of glyoxal is applied to an absorbent paper web in an amount such that the total moisture content in the web after application is between 4 and 20% by weight of the bone-dry web, and the moisture content is substantially maintained while the web ages, preferably at a temperature between 60‹ and 80‹F The moisture content may be maintained during ageing by storage in an atmosphere of high humidity, or by wrapping in a sheet which is sufficiently impervious. The treated paper has a high initial wet-strength but one which decays in a few minutes after wetting. The treated paper may be made by forming paper on a paper-machine, drying and creping it bringing two such webs together, partially pulling out the creping, ironing the compound web, and then applying an aqueous solution of glyoxal to at least one surface. Four embodiments are described. As shown a web 2 of tissue paper is creped off a yankee drier 4. An aqueous solution of glyoxal from tray 11 is picked up by roll 10, and transferred by metering roll 8 to the web. Roll 7 applies light pressure, and the product is rolled up at 14. In the second embodiment, (Fig. 2, not shown), a web from a roll is passed over an applicator roll and then rolled up again. The applicator roll is patterned, dips directly into glyoxal solution in a vat, has a doctor blade to remove excess solution and may be rotated in either the same direction as or the direction opposite from the web. The third embodiment (Fig. 3, not shown) is similar, but the solution is picked up by a metering roll of intaglio type with a doctor blade to control the amount. It is transferred to a second cylinder which applies it to the web. A rubber-covered roll may be provided to press the web on to the transfer roll. In the fourth embodiment, (Fig. 4 not shown) a multiply paper web is sprayed with glyoxal solution from both sides, passed between two pressure rolls and then folded or wound for conversion to end products.
