Title: Improvements in or relating to thermionic valves for use in radio signalling systems
IPC: H03L1/04
Filed: 1934-01-31
Abstract: 437,804. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London. (Assignees of Smith, J. C. ; 4618, Layayette Avenue, Merchantville, New Jersey, U.S.A.) Jan. 31, 1934, No. 21769 /35. Convention date, Jan. 31, 1933. Divided out of 437,726. [Class 39 (i)] A valve for use in a circuit as a combined mixer and local oscillator has five electrodes interposed between the cathode 61 and output anode 54, the two electrodes 52, 67 nearest the cathode serving in the local oscillation circuit ; the second electrode 67 has an area which is only a small fraction of the cross-sectional area of the electron stream between the cathode and anode, so that it is adapted to influence the electrons over only a small part of the stream. In one construction this electrode, which acts as an anode for the oscillator, is in the form of one or more rods. Screen electrodes 87, 72 which are connected together within the valve are interposed as shown between the input grid 66 and (a) the oscillator electrodes and (b) the anode 54. The circuit arrangements are as described with reference to Fig. 8 of Specification 437,726. The control grid 66 may be of the exponential type to form a variable-mu valve.
Patent GB-763445-A (GB)
Title: Process for the manufacture of films and film coatings of polyvinyl alcohol
IPC: B29C41/28
Filed: 1953-08-06
Abstract: <PICT:0763445/IV(a)/1> Polyvinyl alcohol films are obtained by an immersion method in which a band is coated on one or both sides and guided vertically through a bath of polyvinyl alcohol solution, and the solution is pressed against the band by rollers rotating in the bath.  The band continues to move vertically after it has left the solution and during the drying of the film layer or layers.  The dried films are stripped from the band.  Preferably, the band is guided between rollers located in the bath at different heights and in staggered relation so that the band contacts the rollers over a substantial part of their surfaces.  After the band leaves the immersion bath it passes over a short distance in which a smooth surface is allowed to form on the coatings.  This may be assisted by spraying water or a thin solution of polyvinyl alcohol on to the surface or by treating it with wet wiping rollers.  The coated band is then passed through a drying zone, drying being effected by means of warm gases, radiant heat, infra-red radiation, or other means. The band may then pass to a cooling zone.  Films of greater thickness may be obtained by repeated immersion of the band.  The dry films are continuously removed from both sides of the band, and if desired they may be stretched.  The expression "polyvinyl alcohol" includes derivatives of polyvinyl alcohol which still contain free hydroxyl groups and which are soluble in water or aqueous liquids.  The forming-band may be of polyvinyl chloride or a polyvinyl acetal, or of steel, chrome-nickel steel, nickel or chrome-plated steel, brass or copper.  The surface of the band may be smooth or polished or may have a relief or profile pattern.  Coloured polyvinyl alcohol solutions may be used or the surface of the band may be prepared by applying a colouring matter uniformly or in pattern so that the surface of the film becomes coloured.  In an example, an endless band of polyvinyl chloride is coated with a solution of a wetting agent and dried. It is passed through a solution of polyvinyl alcohol and the solution is pressed on both sides of the band by staggered rollers.  The band is passed vertically upwards out of the bath and dried by exposure to infra-red radiation.  The dry films are stripped from the two sides of the band.  As shown, an endless belt B is driven by drum R and guided by rollers W1, W2 to a dipping bath T where it is immersed in a solution of polyvinyl alcohol.  Immersed rollers W3, W4 press the solution against the belt.  The films F1 and F2, formed on opposite sides of the belt, are stripped off as the belt is deflected round the rollers W5, W6.

Title: Method of improving the dyeability of textile fibres, films and the like
IPC: D06P3/40
Filed: 1959-06-25
Abstract: The dyeability of articles made from homopolymers or copolymers of acrylonitrile, methyl methacrylate or vinyl chloride is improved by incorporating therein a polyethyleneimine of the type containing a <FORM:0921422/IV(a)/1> group, in which R is hydrogen or an alkyl or aryl group, which has been rendered wholly or partially insoluble in water, the polyethyleneimine : polymer ratio being from 1:9 to 20:80. Polyethyleneimines specified are those which have been water-insolubilized by treatment with hydrogen peroxide, acidified potassium persulphate or hexamethylenediisocyanate, or cyanoethylated with acrylonitrile.  In the examples (1) polyacrylonitrile and polyethyleneimine which has been treated with hydrogen peroxide are dissolved in dimethylformamide to provide a solution from which fibres are spun which are dyeable with acid dyes; (2) polyethyleneimine which has been treated with hydrogen peroxide and polyvinyl chloride are dissolved in a mixture of trichloroethylene and nitromethane, and from the resulting solution fibres are spun which are treated with hexamethylene isocyanate prior to dyeing; and (3) a mixture of p  polyacrylonitrile and cyanoethylated polyethyleneimine are dissolved in dimethyl formamide, and from the resulting solution dyeable films are prepared.

Abstract: 741,368. Colour television tubes. EDISON SWAN ELECTRIC CO., Ltd. July 24, 1953 [Aug. 29, 1952], No. 21825/52. Class 39 (1). A colour television receiving tube comprises an apertured plate 3<SP>1</SP>, Fig. 6, coated with a plurality, preferably three, sets of phosphors on the surface facing away from an equal plurality of guns 16, the phosphors and apertures being arranged in a recurring pattern and a transparent secondary emissive electrode 7<SP>1</SP>, so that primary electrons directed obliquely through the apertured plate 3<SP>1</SP> strike the electrode 7<SP>1</SP> and generate secondaries which excite a colour phosphor on screen 3<SP>1</SP>. The secondary emissive electrode may comprise the tube end wall with a conductive transparent coating upon which a secondary emissive coating is formed, or a separate plate or coating on a plate inside the tube envelope. The beams are directed at different angles so that each beam excites a phosphor of different colour. The secondary emissive and screen electrodes may be spherically shaped, Fig. 4 (not shown), in which case all apertures and colour dot groups have identical geometry, or planar as shown. In the latter case the spacing of the apertures and colour dot groups varies progressively from edge to edge of the electrode for the tilted arrangement or if the electrode is planar but not tilted from the centre to the edges. The colour dots 10, 11 and 12 and apertures 4 may be arranged as shown in Figs. 2, 3 or 8. The guns may be adjusted independently to control the relative colour intensities; they may be parallel, the beams being deflected to the correct trajectories by a common electron lens, or may be relatively tilted to converge the beams. They may be grouped round the axis or arranged side by side in a row. The tube may be used with frame, line or dot sequential or simultaneous systems, and the scanning can be by electrostatic or electromagnetic means. It may be used in broadcasting systems or in short distance transmission systems in which the video signals are transmitted over lines and no carrier wave is employed. A theoretical discussion of the screen structure is given. Specification 720,315 is referred to.

Filed: 1972-05-12
Abstract: 1434188 Timing GENERAL ELECTRIC CO Ltd 11 May 1973 [12 May 1972] 22410/73 Heading G4A A time out routine to time operations in a data processing system is effected using storage locations for storing binary digits, the locations being examined sequentially, the storage location immediately previously examined being set to its one state to commence a time out routine and an expired routine being effected when the location is next examined if the location has not been reset. As described one of N storage locations for W words of B bits (giving W.B possible independent time out routines) is examined when a clock pulse initiates the routine by setting a pointer I equal to 1 to access location 1. Each of the words of the location are then sequentially examined and if any word contains a " 1 " bit, the least significant one bit J is selected, reset to 0 and the expired routine appropriate to the bit number and the word number selected. The word is then again accessed until none of its bits are " 1 " when the next word is accessed. When all the words in the storage location have been processed the storage location numbers are updated cyclically so that at the next clock pulse the next location is examined. A time out routine is commenced by accessing a selected bit J of a selected word I in accordance with the required routine in the Nth storage location, i.e. the immediately previously examined location and setting the selected bit to 1. A time out is removed by calculating the bit J of the word W appropriate to the routine it is required to cancel and using this information to access all the storage locations to reset the selected bit J in the selected word W to zero.

Abstract: 1388145 Preparation of potassium dihydrogen phosphate; fertilizers FITZWILTON Ltd 14 May 1973 [12 May 1972] 22429/72 Headings C1A and C1B Potassium dihydrogen phosphate and soluble polymerized forms of this salt are prepared by reacting KCl and H 3 PO 4  in a molar ratio of P to K of 1 : 1 to 1À25 : 1 and blowing air through the reaction mixture to remove HCl. In an example, fertilizer grade KCl was fed at a constant rate (1800 g./hr.) with phosphonic acid to an air sparged reactor at 250‹ C. The ratio of H 3 PO 4  to potash in the feed was such as to give a product containing 1À1 moles P/mole K. The product from the reactor was passed to a second reactor working under the same conditions and this yielded a product containing 7À7% free acid, expressed as P 2 O 5  and 1À5% chloride. This product was either used directly as a fertilizer or heated with water at 110‹ C. for 2 hours to hydrolyse the phosphates, followed by vacuum drying to yield a hydrolysed product.
