Title: Improvements in magnetic core memory devices
IPC: G11C11/08
Filed: 1956-11-07
Abstract: 845,431. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 7, 1956 [Nov. 10, 1955], No. 34049/56. Class 40 (9). [Also in Groups XIX and XXXV] A magnetic core storage element comprises a magnetic core having a central aperture, a first portion of the core being divided into two legs 16, 18 to provide parallel flux paths and each leg bearing an input winding x, y. A second portion of the core is also divided into two legs 20, 22 and a sensing winding S is provided on the leg 22. Windings x and y are such that when negative current pulses are applied to each of them the fluxes in legs 16 and 18 are both upwards and the flux pattern # of Fig. 4a is established. If, now, either of these currents is reversed two localized fluxes # 2 , # 3  (Fig. 4b) are produced. To produce an output pulse in winding S the flux in leg 22 must be reversed and this can only occur when simultaneous similar currents are produced in x and y. Unlike prior art devices the current in x or y no longer has a critical maximum value since excessive current only saturates the left-hand part of the core. In a modification (Fig. 5, not shown) the core has three input winding legs each with its own winding, similar current in all three windings being necessary to switch the core. Storage arrays.-Fig. 6 shows a two-dimensional array of elements provided with x and y windings as before and with a common inhibiting winding z linking either the x or y drive leg so that energization of the z winding z prevents switching of the core. A three-dimensional array may comprise a plurality of such planar arrays superposed, energization of particular x and y windings switching all similarlypositioned cores (i.e. a word line) in the planes, unless the z winding for a particular plane is energized. The x and y windings are energized selectively through a decoding matrix 25 and a pulse driver 26. The decoding matrices or address selecting systems 25 may be in the form of crystal diode matrices, and the pulse drivers may be magnetic cores as disclosed in Specification 789,096, or transistors as disclosed in Specification 828,708. To write a word in the array the x and y windings are pulsed to store a " 1 " unless the inhibit winding z is pulsed when a " 0 " is stored. The z winding is pulsed by a driver 40 triggered by a pulse from a memory buffer register 34 through an " and " gate 36 which is opened during the write cycle by control 38. Information is placed into the register 34 during a read cycle through sense amplifier 30 and " and " gate 32. Other means may feed information to the register 34. Specifications 783,918 and 841,426 also are referred to.

Title: Improvements in electrodes or welding rods for use in welding
IPC: B23K35/04
Filed: 1937-12-09
Abstract: 507,159. Uniting by fusion. SUREARC ELECTRODE CO., Ltd., and CALOW, F. W. Dec. 9, 1937, No. 34138. [Class 83 (iv)] A welding electrode or rod of the type provided with a flux paste coating has an outer coating of non-slagging fabric, such as muslin, of such open mesh that the greater area. of the flux remains exposed. This fabric is firmly applied to the outer surface of the flux coating either when the flux coating is dry und hard or when it is soft so as to become embedded within the surface of such flux coating. This wrapping permits bending of the electrode without undue rucking and prevents the flux coating from flaking. The outer covering c may be applied helically in a continuous length, or in cut lengths as a wrapping. The fabric may be previously treated so that the destruction of the fabric by heat will not deleteriously affect welding. One or more further layers of the fabric may be embedded in the flux coating b either by winding a layer on the core a previous to applying the flux or by incorporating the same within the'thickness of the flux during extrusion of the flux. Specification 413,509 is referred to.

The shutter has an external detent by which it is movable and interengageable formations on the wall and detent secure the shutter in closed position where it is releasable by a separate device or tool. In the cartridge shown, a thin resilient shutter 44, extending in both directions from a resilient bifurcated detent member 45 is moved thereby to slide in external walls 13 and 15 to cover and expose access apertures 17 and 18, detent heels 49 projecting outwardly into, and locking with, recesses 125 in side edges of an opening 50 and into recesses 126 at closed and open positions of the shutter. When the (closed) cartridge is required to be operated, e.g. with a player, it is inserted into a fixed housing 110, Fig. 7, and located therein by a resiliently mounted member 112. As insertion is effected a resiliently mounted pawl 122 rides over detent 45 and engages its rear wall and a stationary pawl 124 attached to the inside of the wall 114 of the housing 110 catches the detent so that a V-notch 123 flexes the tips 119 inwardly to free heels 49 from recesses 125 and slide the shutter into open position and allow a transducer head 131 and capstan 91 to pass through apertures 17 and 18. When the cartridge is withdrawn from housing 110, the shutter is moved automatically into closed position by the engagement of detent 45 between the tip of pawl 122 and the rear wall. In another embodiment, Fig. 13 (not shown) locking heels on the detent engage shoulders projecting from the edge detent engage shoulders projecting from the edges of opening 50.

Title: Improvements in or relating to Sputtering Apparatus
Inventor: HOLLAND LESLIE ARTHUR
IPC: H01J37/34
Filed: 1966-07-29
Abstract: 1,169,747. R.F. sputtering. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. July 19, 1967 [July 29, 1966], No.34235/66. Heading C7F. In a R.F. sputtering process a pair of non grounded co-planar electrodes associated with the material to be sputtered are mounted in a vacuum chamber, a glow discharge is initiated and a R.F. voltage applied to the electrodes. A magnetic field may be applied near the electrodes and bias sputtering may be effected by means of a second pair of non grounded co-planar electrodes which form part of a carrier for preferably an insulating substrate. A R.F. voltage applied to the second pair is of such a value in relation to the size of these electrodes that the substrate is bias sputtered with an intensity less than that of the sputtering of the source material. The material to be sputtered may be the material of the electrodes or an insulating material e.g. glass coating the electrodes or bridging the electrodes. The electrodes may be round discs, D-shaped, or a round disc surrounded by an annulus. (Registered Trade Mark) "Pyrex" may be sputtered on to lead oxide glass, SiO 2  on to glass and cermets may also be sputtered from a target comprising an insulator with metal strips across its exposed surface. As shown in the figure accompanying the provisional Specification two D-shaped co-planar electrodes 3 and 4 coated with a glass target 7 are attached to a R.F. source and a sputtered deposit is formed on substrate 8 which may rotate above the target 7 and may also be water cooled. Figs. 4, 5 and 6 (not shown) show bias sputtering arrangements, each with two pairs of D-shaped, disc shaped and concentrically arranged coplanar electrodes. In order that the bias sputtering is less intensive than the main sputtering the bias electrodes are tapped on to the secondary of the transformer to give a lower R.F. voltage, a suitable power ratio between main and biased being 10:1. The discharge may be generated and maintained by the R.F. source, or it may be proceeded by an anode cathode system. The R.F. source is between 10 Kc/s and 100 Mc/s to provide an operating voltage 500 Volts to 5 KVolts.
