Title: Improvements in or relating to devices incorporating bi-stable magnetic elements
Inventor: WILLIAMS MICHAEL
IPC: H03K17/84
Filed: 1959-07-12
Abstract: 905,338. Electric digital-data-storage apparatus. GENERAL ELECTRIC CO. Ltd. July 7, 1960 [June 12, 1959], No. 20250/59. Class 106 (1). [Also in Group XXXIX] In a data store utilizing matrix planes of thin magnetic film elements having parallel easy axes of magnetization (four partially wired planes 1a-1d being shown), a plane of elements 2 has associated column and row conductors 6, 7 (plane 1a) respectively arranged parallel and at right-angles to the easy axes, a pick-up conductor (plane 1b) arranged parallel to the easy axes, and an inhibit conductor (plane 1c) which is wired so as to be parallel to both sets of conductors. To register a binary digit in a particular element, a switching current and a crossfield current are respectively applied in coincidence from sources 9 and 8 to a row, and a column conductor, switching of an element being restricted to a required plane by the selective application of inhibit currents from sources 10a-10d. Destructive read-out is effected by connecting a crossfield current before a reverse switching current is applied. When the two currents are coincident, a pulse is induced in the pick-up conductor of each plane which is distinguished from noise by opening gates 4a-4d at an appropriate time. The films are composed of 80% nickel, 20% iron and are deposited by evaporation on to a polished glass or aluminium sheet. Separate elements may be deposited by masking, or a single overall film may provide a number of discrete storage regions, in either case the easy axes being aligned by prepolarization. The pick-up conductor, and some of the other conductors, if required, is duplicated in each plane, one path lying on each side of the film. The pick-up circuit is completed by a terminating resistor 5. In the case of an aluminium sheet substrate, this material may comprise one of the parallel paths. Some or all of the conductors may be applied in the form of evaporated thin films which are separated by evaporated or lacquered insulating layers. Alternatively, printed insulating sheets assembled in a stack may be used. Mention is made of forming a plane from two or more filmbearing substrates having respective duplicated pick-up conductors interconnected by twisted wires.

Title: Improvements in and relating to yarn twisting devices of double twist spindles
IPC: D01H1/10
Filed: 1949-08-05
Abstract: 682,390. Thread tensioning devices. NORTH AMERICAN RAYON CORPORATION, and KINGSBURY, C. B. Aug. 5, 1949, No. 20443/49. Class 120(ii) A yarn tensioning device applicable to twisting machines having spindles 27 adapted to impart a double twist to the yarn for each turn of the spindle comprises a magnetic disc 62, supported on the end of a stationary cap 24 retaining the yarn package on a stationary holder 11, adapted to be attracted by a magnet 69 within the cap 24 to cause the yarn to be gripped between the disc 62 and nose 58 of the cap and thereby restrict the passage of the yarn. The disc 62 has a central projection 63 which extends through an aperture 60 in the nose 58 into a central bore in the magnet 69, the yarn passing from between the disc and nose through the aperture 60 by extending past its edge and the outside of the projection 63. The magnet is retained in position by being urged against the underside of the nose 58 by a spring 71. The yarn after passing through the magnetic tensioning device is drawn through the central bore of a stationary guide tube 19 in the upper end of which is a member 56 having fur or plush-like material for engaging and further restricting the passage of the yarn. The tube 19 supports the cap 24 at its upper end and is screwed at its lower end to an upstanding boss 17, 18 within which are supported bearings 28, 29 for the upper portion of the hollow rotary spindle 27. The lower end of spindle 27 is mounted in a bearing support 35 connected to a pivoted arm 41. A whorl 44 is secured to the spindle 27 and is also rigidly attached to a wheel 52. The bore of the spindle 27 communicates with three holes 53 extending radially in the wheel 52 by corresponding apertures 48 and openings 47 formed in the spindle and whorl and through which the yarn extends as the spindle, whorl and wheel are rotated. The yarn passing from the hole in the wheel is drawn by a take-up device above the assembly and in so doing is bellowed outwardly by the speed of rotation. The spindle and package are disposed at an angle to the vertical and by providing a weight 81 attached to the boss 17, 18 the holder 11 and package 10 are retained stationary during the rotation of the spindle. A brake 85 is provided for stopping the spindle after the whorl has been removed from contact with the driving belt 45 by pivoting the assembly about a pivot 84 connected to the arm 41. Specification 653,518.is referred to.

Title: Method of Preparing Chlorine from Hydrogen Chloride Acid
IPC: B01J21/00
Filed: 1967-05-03
Abstract: 1,181,906. Ghlorine. SOC. ITALIANA RESINE S.p.A. 3 May, 1967 [3 May, 1966], No. 20497/67. Heading C1A. Chlorine is made by oxidizing hydrogen chloride with molecular oxygen in presence of a catalyst comprising a natural or synthetic silico-aluminate of an alkali or alkaline earth metal, wherein a portion of such metal ions has been replaced by ion exchange, by ions of iron, copper, chromium, cobalt or manganese, the silico-aluminate being substantially free from deposited salts of such metals. The catalyst may be a natural or synthetic zeolite, e.g. a molecular sieve of pore size 4-5 Š, in which a portion of the calcium or sodium ions has been replaced by ions of the above metals. Cupric ions, when used, may be in admixture with ions of rare earth metals (atomic number 57-71 inclusive). The catalyst may be used as a fixed or fluidized bed, with a reaction temperature of 320-450‹ C. The catalyst may be obtained by percolating, through a molecular sieve, a solution of the metal ions to be introduced, non- chemically absorbed ions being removed by repeated washing, or by adding to the sieve a calculated amount of the ions, e.g. as chlorides and then evaporating to dryness. When the percolation method is used, the molecular sieve may initially be converted to acid form by washing with 2N-5N acid, e.g. hydrochloric acid, followed by water-washing.

Title: Yarn unwinding devices
IPC: B65H59/06
Filed: 1976-05-18
Abstract: 1535393 Yarn unwinding device OFFICINE SAVIO SpA 18 May 1976 [20 May 1975] 20537/76 Heading D1J A device for disrupting a yarn balloon formed during unwinding of yarn from cops, and shown in plan view in Fig. 2, comprises a plate 11 that is curved so as to extend partially around the longitudinal axis of the cop 15, the plate extending along the whole height of the cop and supporting a threadguide loop 18 above the cop. In Fig. 2 the plate 11 is supported by lugs 12 having elongated slots 16 therein so that the plate 11 can be moved to and from the cop 15 to a desired setting. The plate 11 hasvertically spaced apertures through which the thread-guide loop 18 can extend and thus permit the spacing of the loop 18 from the top of the cop 15 to be varied. Fig. 4 shows a modified thread guide loop 19 that may replace the loop 18. The radius of formation of the plate 11 may be between 1¢ and 4 times the diameter of the cop and may subtend an angle of less than 180. As the yarn is unwound from the cop 15 the resulting balloon produces a beating action against the plate 11 to produce periodic tensioning thereof. This ensures an improved withdrawal of yarn even when only the bottom layers remain on the cop. The loop 19, presenting a flat face to the cop below it, does not allow coils to fly and become entangled in the yarn balloon itself.
