Patent GB-922602-A (GB)
Title: A data storage device
IPC: G11C7/02
Filed: 1960-06-17
Abstract: 922,602. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 17, 1960 [June 30, 1959], No. 21315/60. Class 38 (2). [Also in Group XXXIX] In a storage element comprising a thin magnetic film 10 having two stable remanent states along an easy axis of magnetization 12, non-destructive read-out is effected by an alternating magnetic field applied at right-angles to the easy axis of magnetization by a signal of frequency f in a drive winding 32, and the remanent state along the axis is indicated by the phase O or of a harmonic output frequency 2f induced in a control winding 34, this winding being arranged at right-angles to the control winding and tuned to the harmonic frequency by a parallel condenser C. The film nas a composition of approximately 83% nickel and 17% iron and is evaporated or otherwise deposited in a high vacuum on to a glass substrate to a thickness of approximately 2,600 Angstroms. The desired remanent state is initially established in the film by coincident write signals applied to windings 32, 34, the direction of current flow determining the direction of remanent magnetization along the easy axis. The second harmonic output signal is stated to be obtained as a result of magnetization oscillation over a range on each side of the easy axis, and the arrangement has the stated advantage over prior art of preventing any tendency of domain growth towards the opposite remanent state under repeated read-out conditions due to film defects. The stable state of the film may also be reversed by continuing the alternating energization of winding 32 and applying to winding 34 a sinusoidal current of frequency 2f which is 180 degrees out-ofphase with the existing output signal. The use of two separate windings in place of winding 34 is suggested. Specification 887,157 is referred to.

Patent GB-887875-A (GB)
Title: Bonding polyolefins to metals by means of a chemically modified polyolefin resin
IPC: B32B15/08
Filed: 1959-06-23
Abstract: An adhesive composition, used for bonding metals to polyolefine resins (see Group VIII), is a curable polymer mixture comprising a peroxide catalyst and an oily polymer or copolymer of a C4 to C6 conjugated diolefine, which polymer or copolymer has been modified by incorporation of oxygen in the structure thereof. The oily polymer or copolymer may be further modified with a cross-linking agent, which may be styrene, vinyltoluene, a halostyrene, a vinylnaphthalene, an alkyl acrylate or methacrylate, or an allyl ester, such as diallyl phthalate.  The adhesive may be cured at elevated temperature and pressure, and the cure may be followed by a post-cure at elevated temperature.  An oily copolymer of butadiene and styrene is prepared by charging into an autoclave, with a mechanical agitator, butadiene, styrene, straight-run mineral spirits boiling at 150 DEG  to 200 DEG C., dioxane, isopropanol and finely divided sodium.  After 4-5 hours, the catalyst was destroyed and removed, and the solvent stripped out. Oxygen may be incorporated by blowing this oil with air or oxygen, preferably in the presence of a solvent, e.g. an aromatic hydrocarbon (toluene in Example II), and a catalyst, e.g. an organic salt, such as the naphthenate, octoate or oleate, of a metal, such as cobalt, lead, iron or manganese.  Alternatively, oxygen may be incorporated by adding an anhydride of an unsaturated dicarboxylic acid, preferably maleic anhydride to the oil after polymerization, and heating.

Title: Improvements in or relating to electro-acoustic transducers
IPC: H04R21/04
Filed: 1953-08-04
Abstract: 747,023. Electroacoustic transducers. WARNER, H. C. Aug. 4, 1953, No. 21510/53. Class 40(4). An instrument such as a pick-up or microphone in which the resistance between electrodes in a fluid medium is varied in accordance with mechanical vibrations comprises three chambers each containing an electrode and filled with fluid and means is provided for varying in opposite senses the size of orifices connecting the central chamber with the outside chambers. In a pickup, Figs. 1, 5, 8, chambers 12, 13, 16 formed in a block 11 and filled with electrolyte are closed at their lower ends by a flexible diaphragm 17 of soft rubber or latex, and the stylus 30 carried by a supporting member 36 having a raised rim holding the diaphragm against the cylindrical wall of the central chamber serves to flex the diaphragm as in Fig. 8 to vary the size of the inter-electrode path through the electrolyte. The supporting member is held in yielding engagement with the diaphragm by means of a soft rubber cushion 39. The tension is adjusted to give a linear change of orifice when plotted against needle deflection and the differential arrangement renders it suitable for connection to a push-pull amplifier as in Fig. 10 (not shown). Connections to a single valve amplifier are also described. The electrodes may comprise a thin metal lining or a metallic deposit on the walls of the chambers. The electrolyte may be a solution of cadmium sulphate in ethyl alcohol with cadmium electrodes, or a solution of alum in ethylene glycol with electrodes of a nickelsilver alloy. A conductive gas such as argon or neon may also be used. An alternative embodiment having three parallel chambers cut lengthwise in a block and having the working diaphragm across the top is described with reference to Figs. 11-22 (not shown), the electrodes being embedded in the block and running the length of their respective chambers. The stylus holder is in this case extended in the form of a crucifix across the top of the diaphragm. A similar unit, Fig. 25, forming part of a microphone, may be actuated by a diaphragm 105, Fig. 26, which is dimpled or corrugated for additional stiffness and attached by supporting vanes to the cross-piece 113. Springs 117 hold down sponge rubber pads 118 so that the gap between the chambers is limited to an area in the vicinity of the cross-piece 113. A further embodiment in which a number of rows, each of three chambers, have their electrodes interconnected to give an additive effect is described with reference to Figs. 27-30 (not shown). The use of such a variable-resistance instrument as an amplitude or phase modulator and as a sub-aqueous signalling unit is also mentioned.

Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H03K17/81
Filed: 1956-07-13
Abstract: 803,300. Controlled non-linear inductors. STANDARD TELEPHONES & CABLES, Ltd. July 13, 1956, No. 21804/56. Class 40 (9). A magnetic switching arrangement which sequentially applies full amplitude read and half amplitude write pulses to each row lead of a magnetic information storage matrix comprises cores 1A-9A, 1B-9B having substantially rectangular hysteresis characteristics which are positioned in columns and rows with a pair of cores such as 1A, 1B located at each intersection, a selected core being driven from a normally saturated condition into the unsaturated region by triple coincidence of pulses applied to a column winding W4, a row winding W3 and a " pair " winding W2 whereby the core provides an effective electromagnetic coupling to an output winding W1. Two sets of "pair" windings are provided, one being associated. with the A cores and the other with the B cores, and the windings are alternately energized over leads T1, T2 by pulses t1, t2, each having a duration corresponding to the read and half-write pulse period. The column and row windings are also energized over leads C1-C3 and R1-R3 respectively by pulses c1-c3 and r1-r3 having durations and time positions as shown in Fig. 2, the pattern of pulse energization establishing cycles in which each core of the switch is desaturated in turn in the order 1A, 1B, 2A, 2B ... 9A, 9B by triple coincidence of pulses in the C, R and T leads. These pulses act in opposition in the leads to continuous biasing currents which normally maintain the cores in the saturated state. A single lead which threads all the cores of the switch and is not shown in Fig. 1, is energized by read and half-write pulses which are transferred to the output winding W1 of an unsaturated core, each output winding being connected to an individual row lead of the storage matrix which are arranged in two separate groups U and L. The storage cores are constituted by separate holes in a common ferrite block or plate and are arranged such that certain cores are associated with a single row and a single column lead, such as those cores threaded by column leads CW1, CWN, whereas two row leads are associated with other cores such as those threaded by column lead CW2.

Title: Improvements in or relating to knitting-machines
IPC: D04B9/40
Filed: 1919-09-04
Abstract: 154,996. Wade, H., (Jenckes Knitting Machine Co.). Sept. 4, 1919. Circular machines with rotary needle, cylinders and long and short butt needles for seamless hose &c. arc provided with means to facilitate the transfer to rib tops &c. The side cams 46, 48 or the side cams and tuck ring 54 are lowered to permit the needles 4 to be levelled at the knock-over lavel a, a<1> by a levelling cam which may or may not also act as one of the stitch cams 42, a cam 52<1> and the other stitch cam 44 being withdrawn radially by pattern mechanism. When thus levelled, the upper ends of the needles 4 are below the web holders 6 so that a transfer quill cup can be accurately applied. The tuck ring 54 is lowered by a cam ring 78 provided. with cam plates 80 having cam grooves 82 engaged by pins 84 on the ring 54. The cam ring 78 is held normally in position against the pull of a spring 86 to support the tuck ring &c. in the elevated or active position by a latch 90, the inner end of which engages a notch in the fiange of the ring 78 while the outer end engages a vertically-movable bar 94 under control of the pattern mechanism. The needle-cylinder 2 is carried on a gear ring 12 mounted in a supporting spring-controlled ring 14 carrying three spiral or worm ribs 18 held in engagement with vertically adjustable pins 20 by rolls 22 acted on by heavy springs 26. This adjustable three-point suspension enables the cylinder to be accurately positioned in setting up or re-adjusting the machine and the rotation of the ring 14 raises or lowers the cylinder 2 to regulate the length of loop. After the levelling of the needles for transference a quill cup 122 carrying a fabric is applied to the web holders, and an abnormal rotation of the ring 14, under control of the operator, who releases a stop pin 118 connected to a thumb-piece 120 from a tooth 116 projecting outwards from the ring 14, lowers the needle cylinder 2 and causes all the needles except those indicated at b, b<1> to be projected up into the quills. The needle cylinder is thus drawn down carrying with it the needles at b, b<1> the butts of which register with the depressions between the side and centre, cams, until a second stop-tooth 124 on the ring 14 is arrested by a fixed stop pin 126. The operator then gives the cylinder 2 a partial turn to bring the needles at b, b<1> up into the quills and the quill cup is then removed. The machine is next started and the pattern mechanism forces the worm ring 14 back into position to elevate the needle cylinder to normal knitting height, and the cam ring 78 is also automatically returned to raise the back ring 54 and the cams carried thereby into knitting position. The cams 44, 52<1> are then released while the short-butt needles are passing, and after riding on the remaining short butts start the knitting on the long butt needles.
