Title: Improvements relating to magnetic storage elements
Inventor: STAPLETON DAVID CHRISTOPHER
IPC: G11C15/02
Filed: 1966-11-02
Abstract: 1,201,610. Magnetic structures; magnetic storage arrangements. PLESSEY CO. Ltd. 16 Oct., 1967 [2 Nov., 1966], No. 49235/66. Heading H1H. [Also in Division H3] Each magnetic storage element in a matrix store (see Division H3) comprises a non-magnetic word conductor 11, Fig. 2, having continuous superposed films 12, 14 of anisotropic magnetic material with high and low coercivities, respectively, and an orthogonal digit conductor 15, the preferred magnetization direction of the high coercivity film 12 being substantially parallel to the word conductor, while the preferred magnetization direction of the low coercivity film 14 is inclined slightly, e.g. by 5 degrees, to the axis of the digit conductor. Writing is effected by applying pulses simultaneously to the word and digit conductors so as to establish " 0 " or " 1 " characterizing closed loop magnetizations 16, 17, Fig. 3, through the high and low coercivity films of a storage element. Non-destructive read out is effected by applying a pulse to a digit conductor sufficient to permit the magnetization of the low coercivity film to move away temporarily from its hard direction in which it is normally held by the field of the high coercivity film. Alternatively non-destructive read out is obtained by pulsing the word conductor, in either case the pulse being insufficient to disturb the magnetization of the high coercivity film. A non-magnetic film 13, e.g. of copper, may be interposed between the films to prevent diffusion between the films during the formation by deposition.

Title: Low power operated clutch latching mechanism
IPC: F16D11/06
Filed: 1968-10-18
Abstract: 1,221,556. Controlling positive clutches. BURROUGHS CORP. 18 Oct., 1968 [19 Oct., 1967], No. 49567/68. Headings F2C and F2L. A positive clutch has a driving member 57 with diametrically opposite notches 65 engageable by the detent 63 of a latch arm 61 which is pivoted at 59 to a driven member 71 fast on an output shaft 13. A control member 15 is freely rotatably mounted on the output shaft and is driven by abutment of a projection 29 with the latch arm 61. To declutch, a stop member 27 is spring biased into the path of the projection 29 so that the latch 61 is pivoted to disengage the detent 63 from a notch 65. Rebound of the driven member 71 is prevented by engagement of a pawl 73 with a stop surface 79. The stop member 27 is pivoted about a post 31 and has an arm 37 connected thereto at a pivot point 41 and by a tongue and notch connection 43. The arm is pivoted against the bias of a spring 49 by a solenoid 47 to bring a cam follower 39 carried by the arm into contact with a cam 17 fast with the clutch driving member. The clutch is engaged when a lobe 23 of the cam 17 causes the arm 37 and the stop member 27 to pivot simultaneously about the post 31 and thus release the control member 15, whereupon a spring causes the latch member 61 to engage the clutch. On de-energizing the solenoid, a facial cam surface on the cam 17 forces the arm 37 away from the solenoid to ensure removal of the follower from the cam despite possible residual magnetism. A single cycle or continuous operation is obtained by momentary or continuous energization of the solenoid.

Title: Improvements in or relating to devices for supporting a load in a machine
IPC: B21B13/14
Filed: 1963-12-16
Abstract: 1,015,988. Rolling. A.B. SVENSKA KULLAGERFABRIKEN. Dec. 16, 1963 [Dec. 22, 1962], No. 49623/63. Heading B3M. The rolls of a Scudyimir type mill are adjusted for crown using hydraulically operated plungers which are adjustable under load in their cylinders. The first supporting rolls 12 and 13 of the mill are backed by rolls 17 and 18 (Figs. 1 and 3, not shown), the plungers operating between adjacent sections 110 of the rolls 17 and 18. The plunger 115 of each adjuster acts on a saddle-piece 112, bearing against a disc 111, and includes an adjustable abutment 116 at its other end. When a fluid is introduced through a line 121 and radial slots 118 to one face of the plunger, the plunger is moved fractionally to the left, and the abutment 116, now relieved of its load, is adjusted. A spindle 119, having pegs 120 co-operating with slots 118 in the abutment, rotates the abutment causing axial adjustment. A thrust bearing 124 takes up the fluid pressure axial loading on the spindle 119. After adjustment the fluid pressure is released. A similar arrangement is disclosed in which the abutment takes the form of a laterally movable wedge which is movable, when the rolling pressure on it is relieved, by an eccentric peg on the shaft 119.

Title: Method of post-forming electrolytic capacitors
IPC: H01G9/04
Filed: 1969-10-10
Abstract: 1,220,555. Electrolytic capacitors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 Oct., 1969 [10 Oct., 1968], No. 49812/69. Heading H1M. In post-forming an electrolytic capacitor by a direct current voltage source connected to the capacitor through a series resistor, the time required is reduced by interrupting the process at least once and at least partly discharging the capacitor through a parallel resistor. As shown the position of movable switch contact 25 actuated by timed driving gear 26 determines whether capacitor or bank of capacitors 11 to be post-formed are being charged by voltage source 14 or discharged through resistor 24. In a modification (Fig. 2, not shown) a single resistor (28) taks the place of both series resistor 21 and parallel resistor 24. It is suggested that the discharge annuls the polarization of the anode occurring during charging.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/20
Filed: 1965-11-24
Abstract: <PICT:1123384/C1/1> <PICT:1123384/C1/2> In a process for the manufacture of flat glass during which glass is advanced along a bath of molten metal, contaminants in the molten metal are removed by circulating the molten metal through a purifying zone, exposing the molten metal to a vacuum in that zone so that the impurities volatilize from the molten metal, collecting the impurities, and returning the purified molten metal to the bath.  In one embodiment (Figs. 1 and 2) the molten metal is raised from a recess in the bath 1, the recess being defined by side walls 7, end wall 8, and a floor 9 which is a continuation of the floor 3 of the bath.  The pocket of molten metal in the recess is divided into two parts 12 and 13 by a partition 11, and the two parts of the pocket communicate with the main part of the bath through channels 14 and 15.  A vacuum tower is supported above the recess on a support frame 17, and has two hollow legs 18 and 19 which dip into the two parts 12 and 13 of the recess, and which communicate with an upper chamber 20 which defines the purifying zone.  A bore 22 extends through the leg 18 and a similar bore 23 through leg 19.  A branch pipe 29 has a bore 32 which communicates with the bore 22 and allows a non-oxidizing gas to be fed into the bore 22 and up the leg 18.  The purifying zone 20 is connected by a pipe 40 to a condenser 43 and a vacuum pump 49. Operation of the vacuum pump causes a reduction in pressure in the chamber 20 resulting in molten metal filling the legs 18 and 19, and the introduction of the non-oxidizing gas through the branch pipe 29 induces a circulation of molten metal from the part 12 of the pocket of molten metal in the recess, up the leg 18 and into the chamber 20, and then down leg 19 and into the part 13 of the pocket of molten metal, the volatile tin oxide and/or tin sulphide being removed from the chamber 20 through the outlet 36 and pipe 40 to be collected in the condenser 43.  The purifying zone and hollow legs of the vacuum chamber may be made of steel and may have carbon linings.  The molten metal contained in the recess may be contacted by an element with which oxygen and/or sulphur preferentially reacts to form oxides and or sulphides which are readily released from the molten metal in the purifying zone. Phosphorus and carbon are specified.

Title: Fibre reinforced composite of high fracture toughness
IPC: C08K9/04
Filed: 1975-12-08
Abstract: 1515150 Resin fibre composites MASSACHUSETTS INSTITUTE OF TECHNOLOGY 8 Dec 1975 [23 Dec 1974] 50210/75 Heading D1R A plastics matrix is reinforced with fibres coated with a viscous fluid having a viscosity of at least 25 c.p., the practical maximum being about 1,000,000 c.p. Specified liquids are silicone fluid or grease, mineral oil, pertoleum jelly, glycerol, vaseline and a phosphate mould release compound. The fibres may be coated by drawing them through a liquid and removing excess by drawing the coated fibre through a die. The impact strength of the reinforced matrix is increased up to almost 300% because energy is dissipated at the fibre matrix interface due to shear deformation of the viscous layer. The thinner the layer the greater the energy dissipated. The layer should not be so thin that the force resisting fibre pull-out exceeds that resisting fibre breakage or there will be no shear deformation. Preferably the thickness is 0.001 to 25 mils., more preferably 0.1 to 10 mils. The matrix may be a high density polyethylene, acrylonitrile-butadiene-styrene or styrene-acrylonitrile copolymer, polyester, polystyrene, polyvinyl chloride, fluorinated ethylene-propylene polymer, polysulphone, polypropylene, nylon, polyurethane, polyphenylene oxide, alkyd, diallylphthalate, epoxy melamine, phenolic, or polysilicone resin. The fibres may be glass, graphite, asbestos, sisal, nylon or polyvinylchloride. The fibres should comprise 0.1 to 35% by volume of the composite. In the examples 3 ply E- glass yarn having 204 filament strands are coated around a viscous liquid are wrapped around a 9' X 14' frame. 4 frames are stacked together with the fibres orientated unidirectionally and polyester resin poured on. After vacuum removal of entrapped gases the composite was cured at room temp. and then for one hour at 170F. Pressure may also be applied.

Abstract: 1,174,837. Washing textile webs. ARTOS DR.-ING. MEIER-WINDHORST K.G. 8 Nov., 1967 [12 Nov., 1966], No. 50820/67. Heading D1P. Water-soluble treating media, e.g. acids and lyes, are washed from textile webs comprising natural or synthetic fibres or mixtures thereof, by washing them in a first stage with fresh water, squeezing them and then washing them in a second stage with electrolyte-free or desalinised water, the first and second wash stages being connected in series. The term fresh water is intended to refer to water having a lower concentration of the water-soluble treating media than is to be found in the web out of which the media are to be washed. The web may be squeezed again after a treatment time of at least 6-8 seconds in the electrolytefree or desalinised water. Water from the final squeezing and surplus water from any addition rinse process may be added to the first wash stage as extra fresh water. The washing water of the first wash stage may be heated and any condensate which forms inside or outside the washing machine during the heating may be used in the second wash stage. The web may enter the second wash stage at a medium temperature and before or along with the washing in electrolyte-free or desalinised water may be subjected to condensation heating to approximately 100C and may be maintained at this temperature and in a steam medium during the treatment time of the second wash stage. In the drawing the first four chambers 1, 2, 3 and 4 of a six chamber counter flow washing machine are connected one to another, fresh water being supplied at input A and withdrawn at output B, and chambers 5 and 6 also work on the counterflow principle, the water being fed into chamber 6 and passing from there to chamber 5 from which it is withdrawn by pump 12 through filter 10 containing an ion exchange resin and fed back to chamber 6. When the filter 10 becomes exhausted it is regenerated with hydrochloric acid and an alternatively usable filter 11 is provided in order to allow continuous operation.

Title: Method of and Apparatus for Detecting Inhomogeneities in Metal Wires which have been caused by Radiation
Inventor: MEIER ROLF
IPC: G01K7/02
Filed: 1966-11-15
Abstract: 1,150,707. Measuring electrically. EUROPEAN ATOMIC ENERGY COMMUNITY. Nov.15, 1966 [Dec.1, 1965], No.51094/66. Heading G1N. Inhomogeneities in a metal wire caused by radiation are detected by comparing the voltage produced across a length of the wire by the Thomson effect with that produced across an equal length of a similar non-irradiated wire exposed to the same temperature difference, non-equality of voltage indicating an inhomogeneity. Irradiated and non-irradiated lengths of wire, wound on reels 9, 8, Fig. 2, are joined together (or a single length of wire only half of which has been irradiated) and wound slowly on to a ceramic reel 10 in an oven 11 provided with heating coils 12. As the reel 10 rotates it also moves upwards so that the wires are wound helically on to it. The free ends of the wires are connected to a voltmeter, the connections between the wires and the voltmeter leads being immersed in a constant temperature oil bath (19, Fig.3 not shown), inhibit other thermoelectric voltages at these junctions. Temperature gradients will exist in the wire at their entry points into the oven in such directions that the voltages produced will be opposed and equal if their are no irregularities.
