Title: Improvements in or relating to magnetic core devices
Inventor: RODGERS GERALD PATRICK
IPC: G11C17/02
Filed: 1964-12-07
Abstract: 1,096,307. Automatic exchange systems; circuits employing bi-stable magnetic elements. GENERAL ELECTRIC CO. Ltd. Nov. 29, 1965 [Dec. 7, 19641, No. 49668/64. Headings H3B and H4K. A magnetic data storage device has an apertured storage core of rectangular hysteresis characteristic which is coupled by a conductive loop to an apertured transformer core having a low coercivity, each aperture being threaded by respective wires and the transformer core having the larger aperture. The storage core is switched from one stable state to the other by a signal on a wire passing through one of the apertures, a read out signal being induced in a sense wire passing through the other aperture. A 15 x 15 storage array is shown in Fig. 1 in which each storage device 1, 2 . . . represents a binary word. Each device comprises a magnetic storage core 20, 25 threaded by column and row selection wires 11-15, 16-19, a non- saturable transformer core 21 being coupled by a conductive loop to the respective storage core. Eighteen sense wires 9, 10 corresponding respectively to the eighteen digit positions of stored binary words are provided, each wire threading selected transformer cores in the array. Thus if the array is addressed for read out by coincident row and column currents, the switched storage core causes outputs to be induced in each of the sense wires threading its associated transformer core. Constructional details are disclosed, Fig. 2 (not shown), the cores 21, 20 being located on opposite sides of an insulating board 23, which is grooved to support the transformer cores 21, and is apertured for conductive wire loops linking respective storage and transformer cores. An alternative embodiment, Fig. 3, may form part of a translator in a telephone system which produces trains of electric pulses, or combinations of voice frequency signals, representing the digit values of signals applied to a selected one of one hundred number wires 55. A 10 x 10 matrix of storage devices 41, 42 . . . is used, and each sense wire threads a transformer core allotted to a particular decimal digit in each of the rows of the array. Each sense wire by its characteristic threading determines the digits which are induced in column wires 56-61 when the storage cores associated with the sense wire are switched. The cores are initially in the " 1 " state, and after a cycle of operation switched cores are restored to their initial state by a reset signal in wire 68. All the rows of storage cores but one are inhibited from switching by energization of row wires 62-67, the uninhibited condition being transferred sequentially from row to row by a counter 89. Each time a row becomes uninhibited a pulse on the chosen sense wire switches the storage core associated with that transformer core through which the wire is threaded. Consequently the decimal number appears in pulse form on the column wires 86-61.

Abstract: 1,076,589. Photo-electric analysis. PARAMETRICS Inc. Nov.23, 1965 [Nov. 23, 1964], No. 49822/65. Heading G1A. Analysis of a substance to determine its composition or the amount of a particular component is carried out by subjecting it to α-rays and investigating the characteristic X-rays produced thereby. The substance may be investigated by apparatus using backscatter or transmission geometry Figs. 1, 2 (not shown). The source, which may be Po 208 or 210, is arranged in a cup-shaped shielding container with a thin membrane of gold or platinum foil on top. The detector may be a scintillation counter or proportional counter, output of which is submitted to a pulse height analyser feeding a scaler. Counts are made in particular energy ranges, to include the energies of the characteristic X-rays of the different elements in the substance, (gas or solid). Alternatively a group of geiger counters, having different gas fillings, geometries or window materials, and thereby responding to different energy ranges, may be used. Instead of the radioactive source of alpha particles, helium nuclei from an accelerator may be used. The invention is designed to avoid continuous background radiation e.g. Bremsstrahlung being produced from the sample.

Abstract: 1452615 Pulping wood with oxygen MO OCH DOMSJO AB 26 Oct 1973 [27 Oct 1972] 50025/73 Heading D2W In a method of pulping wood with a digestion liquid of pH 7-9 in the presence of oxygen, at least some of the digestion liquid is removed from the digester during and/or after digestion, treated so as to deactivate materials present in the liquid which tends to degrade carbohydrates during digestion and the deactivated liquid is returned for use in the same or another oxygen digestion method. The digestion liquid may comprise an alkali e.g. sodium hydroxide, carbonate, and/or bicarbonate. The deactivation treatment may comprise treatment with an oxidising agent e.g. air and/or oxygen and/or a peroxide and/ or heating to a temperature above that at which the liquid was withdrawn from the digester. Catalysts may be used to speed up the rate of deactivation. Deactivation may also be effected more quickly by irradiating the withdrawn liquid whilst deactivating the latter by treatment with an oxidising agent and/or heating at an elevated temperature. An alkali metal or alkaline earth metal hydroxide or carbonate may be added to the withdrawn liquid before and/or during deactivation. The wood may be pretreated with an alkali prior to oxygen pulping.

Title: Improvements in continuous aqueous prehydrolysis of wood chips
IPC: D21C1/02
Filed: 1964-12-15
Abstract: 1,043,460. Treating wood-pulp. RAYONIER Inc. Dec. 15, 1964 [Aug. 7, 1964 No. 51003/64. Heading D2W. [Also in Division B1]  Wood chips are prehydrolysed by effecting an initial mild hydrolysis in steam or water, passing the prehydrolysed chips and hot water concurrently downwards in contact in a vessel, separating part of the water and dissolved substances, cooling the chips by passing them countercurrently to a stream of water to a temperature slightly above the boiling point of water, and discharging them at atmospheric pressure. As shown, wood chips from hopper 1 are fed into vessel 4, which has steam-supply means 7 and 9 and a screw feeder 5 to force the chips to pocket-feeder 6. Some terpenes &c. are volatilized and removed at 8. The chips fall from pocket-feeder 6 to highpressure feeder 12 and are forced by pump 15 in a slurry to screw-feeder 16. The screw 17 squeezes out some water, which is returned through pipe 18. The chips are then forced along pipe 24 and into vessel 27 by water from pump 25. They move downwards through this vessel to the outlet 34. The vessel has four screen sections 36, 37, 38 and 39. At 36 and 37 the chips are charged with hot water from pipes 40 and 43. Water is drawn from the outside of the screen sections 36 and 37 and recirculated through heat-exchangers 60 and 71 by the pumps 41 and 44. The prehydrolysis take place between screens 37 and 38. At 38 a substantial part of the liquor is removed by pump 46. Pipes 50 and 51 introduce cooling water, and pipe 54 introduces dilute liquor containing dissolved chemicals. These pass upwards and are removed at 39 by pump 55 and taken to the dome 30 at the top of vessel 27. The slurry of chips leaving vessel 27 is led through pipe 35 and enlarged chamber 91 to blow-tank 92 and dewatering screen conveyer 95. Part of the water removed at 38 is recirculated through pipe 74. The rest is sent to flash chamber 77, and the concentrated liquor remaining after flashing-off is collected in tank 81 and taken off to a recovery system (not shown). The level of liquid in the flash chamber 77 is controlled by means of float indicator 78 which operates electric impulse valve 80. The condensate from heat exchangers 60 and 71 is passed to another flash chamber 63, with similar means for controlling liquid level. The recovered steam is sent to vessel 4 for use in the presteaming step. The liquid from separator 63 passes to vessel 66, with a similar level control, where more steam is flashed off together with turpentine and other volatile materials which are taken off through pipe 85 to recovery (not shown). The liquid from vessel 66 is passed through pipe 88 to waste or 89 to a powerhouse (not shown).
