Title: Improvements in information display devices
IPC: G02F1/29
Filed: 1964-03-02
Abstract: 992,452. Photographic type - composing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 2, 1964 [March 5, 1963], No. 8655/64. Heading B6W. [Also in Divisions G4 and H4] A display device comprises means for generating a monochromatic collimated polarized beam of light, electro-optical means having a plurality of regions each representing a character and adapted to be selectively energized by an electric signal corresponding to that character whereby the beam of light passing through the energized region is split into two components one of which is transmitted by analyser means and directed on to display means. Light from a source 10, Fig. 1, is collimated by lens 12, polarized by screen 14 and passed through filter 16 to obtain a beam of the desired frequency. The electro-optical means is a character matrix each character having in the form of a stencil 22 an active crystal 20 behind it. Electrodes are provided for each crystal, a lower one forming part of a horizontal conductor and upper ones connected to vertical conductors 24. The crystals are mounted on a glass backing and an analyser plate 30, placed at 90 degrees to the filter 14 is mounted on the other side of the glass. Each crystal responds to energization of its electrodes by becoming birefringent, rotating the plane of the light beam passing through it. The plate 30 transmits only the rotated portion of the light so that by selecting which electrodes are energized a beam having the shape of a selected character is projected via lenses 42, 44, and positioning means 48 and lenses 62, 64 on to display screen 60. The positioning means consists of an electro-optical ferro-electric crystal having electrodes 52, 54 for applying an electric field along the optical axis whereby the refractive index is altered. The beam is deflected for successive characters 80 that they appear on the screen in a line. The screen 60 is sensitive to light or heat so that the characters are recorded. In the form of Fig. 2 the light source 70 is a laser producing monochromatic light which passes through collimator 14 and polarizer 14 and falls upon matrix 72. This matrix comprises two independent electro-optical mediums 74, 76 and analyzers 78, 80. Each of the mediums 74, 76 has an electrode system, there being aligned horizontal electrodes 82, 84 on either side of medium 74 and aligned vertical electrodes on each side of medium 76. The characters are formed in a mask 89 covering the medium 74. By energizing suitable electrodes the corresponding character is selected as before and deflected by horizontal and vertical deflectors 92, 94 on to display screen 100. Deflection voltages may be derived from a potentiometer having tappings connected in sequence to an output terminal.

Title: Improvements in methods of, and apparatus for, the preparation of ferrous oxide
IPC: C01G49/04
Filed: 1961-03-10
Abstract: <PICT:0980425/C1/1> Ferrous oxide is prepared from ores of higher oxides of iron by reacting a methane-rich gas (i.e. containing at least 25% methane) in a combustion zone with air in proportions for incomplete combustion to form a reducing gas stream, passing the reducing gas stream countercurrent to and in contact with an ore of higher oxides of iron in a reducing zone thereby reducing the ore to ferrous oxide, withdrawing the gaseous effluent from the reducing zone, dividing it into two approximately equal portions, burning one of the portions completely with air in recuperative heat exchange with the other portion and recycling and mixing the thus heated second portion with the reducing gas stream and/or with the methane-rich gas stream, so that the temperature within the combustion zone is approximately 1000 DEG  C.  As shown in Fig. 3, the iron is charged by a screw 2 from a hopper 3, to a gas-tight rotary furnace 1 having an axial burner supplied with a methane rich gas and air through tubes 10 and 11 respectively.  The reduced ore is poured into a tank 4, containing hot water, through a submerged shoot 5, and a chain of buckets 7 or an endless apron removes the oxide and discharges it to a rotary screen 8 in which it dries instantaneously. The gas escaping from the furnace is divided into two substantially equal portions by valves 18 and 19. Air, supplied by fan 20 is added to one of the portions and the mixture burnt in the hearth of heat recuperator 21, the flames passing along tubes 26.  The second portion is drawn in by fan 25 and forced through tubes 26 and thus heated to about 760 DEG  C. This-hot gas is then sent into the peripheral sheath 12 of the burner.

Title: Articles comprising coated polyfluorocarbon substrates
IPC: C08J7/046
Filed: 1962-03-12
Abstract: A normally solid "surface-activated" polyfluorocarbon comprising a thermoplastic material having a molecular weight in excess of 1000 prepared by the polymerization of a compound of carbon and fluorine with or without hydrogen and/or chlorine and/or oxygen and in which there is present from 2-10 carbon atoms is coated with a polyimide having at least 20 recurring units of the structure <FORM:0997391/B1-B2/1> wherein R is a tetravalent radical containing at least 2 carbon atoms, with no more than 2 carbonyl groups being attached to any one carbon atom of said tetravalent radical, and R1 is a divalent radical containing at least two carbon atoms with no more than one free valence bond of the divalent radical being situated on any one carbon atom.  The polyfluorocarbon substrate may be for example polytetrafluoroethylene, polyhexafluoropropylene, polychlorotrifluoroethylene, polyvinylfluoride, polyvinylidenefluoride, copolymers of tetrafluoroethylene and hexafluoropropylene or perfluoromethyl perfluorovinyl ether or perfluoropropyl perfluorovinyl ether.  By "surface-activated" is meant that the substrate is treated chemically or physically or both to provide a strong bond between it and the coating.  The treatment may be by means of etching with sodium, or by treatment with an electric discharge such as a corona discharge.  When a surface of polytetrafluoroethylene is to be coated it may receive a primer coating of a copolymer of tetrafluoroethylene and hexafluoropropylene.  The polyimide coating is produced by applying a polyamide acid to the substrate and converting this to polyimide either thermally or chemically.  Thermo conversion involves heating to above 50  DEG C., and the chemical method may involve the use of acetic anhydride and pyridine.  The process is particularly suitable for coating wire, and many examples are given of coating copper and silver-plated copper wire. Specifications 898,651 and 903,271 are referred to.

Abstract: 1,182,195. Flash-bulbs. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 28, 1967 [March 2, 1966], No.9346/67. Heading G2L. A flash-bulb which may be arranged in a common unit with one or more other flash bulbs and comprising an envelope 13 containing actinically reacting material 14, e.g. zirconium wool, is fitted with two pole wires 16, 17 connected by a filament 15 coated with ignition paste, and an additional electrode 18, the arrangement being such that the pole wire 16 becomes connected to the electrode 18 as a result of the combustion reaction which occurs on ignition of the bulb. Thus when a plurality of bulbs is mounted in a suitable unit whereby they are connected together electrically as shown, ignition of one bulb places the next successive bulb in circuit for firing. The connection may be made in various ways. In bulb 9a, a drop 20 of low-melting-point metal, e.g. Wood's metal, carried by the wire 16a, is melted by the heat of the flash and bridges the wires 16a and 18a, in bulb 9b a non-conductive mass 22 connects the wires 16b, 18b and is rendered conducting by the heat or light of the flash; and in bulb 9c, a thin metal tube 24 connected to the wire 16c and surrounding but spaced from the wire 18c is compressed by the gas pressure occurring during the flash and makes contact with the electrode 18c. The power source 12 for igniting the bulbs may be a dry battery or a Piezo-electric crystal. Reference has been directed by the Comptroller to Specification 1,103,682.

Title: Method of and apparatus for testing combustible gas
Inventor: SILVER LEONARD
IPC: G01N25/54
Filed: 1950-04-18
Abstract: <PICT:0692712/III/1> The approach to explosibility of a combustible gas, due to the presence of oxygen or air therein, is tested by adding to the combustible gas a predetermined proportion of air and leading a sample of the resulting mixture into an explosion chamber, and subjecting the charge when stationary in the explosion chamber to the action of an ignition device.  Any resulting explosion may be used to switch off an electrostatic precipitator used in purification of the gas.  As shown, pumps 5, 10 operated by a coupled power drive 21 through adjustable eccentrics 18, 19, deliver gas and air respectively via a flame trap 14 to explosion chamber 15 where the mixture is subjected to a spark between electrodes 24.  An explosion raises cap 26 and opens switch 31 in the control circuit of the electrostatic precipitator.  A flexible diaphragm may replace the cap 26.  Pumps giving a continuous flow may be used in place of the pumps 5, 10, in which case intermittent supply to the explosion chamber is effected by a diversion valve operated by timing gear.  In an alternative arrangement, Fig. 2 (not shown), a constant sub-atmospheric pressure is maintained on the delivery side of a rotary pump by means of a governor-regulated valve in the gas supply line, and air is admitted through a calibrated orifice plate; two explosion chambers which operate alternately are provided.
