Title: Gas discharge display devices
IPC: H01J11/10
Filed: 1972-12-29
Abstract: 1418043 Matrix displays FUJITSU Ltd 29 Dec 1972 [30 Dec 1971] 60180/72 Heading G5C A display system comprises a gas discharge panel including crossed conductor arrays at least one array insulated from the gas by a dielectric layer, means for producing a lateral discharge P s  between adjacent conductors of one array and moving it across the panel and means for producing a discharge Pd between a pair of conductors of the other array in the region of the said lateral discharge. The panel having shift and display portions 10, 20 comprises substrates 11, 21, conductors k, w, a, b, c, y and insulation layers 12, 22 with partitions 13, 23 forming shift channels; leads extend from both ends of the electrodes. Lateral discharges are ignited by a firing voltage applied to electrodes k 1  k 2  and moved across the panel, between the partitions 13, by phased apart shift pulse trains applied to buses A, B, C, D. Write in pulses are applied between any selected pair of conductors, e.g. y1a, y1b and a discharge Pd is produced in the channel of layer 22 adjacent the instant position of a lateral discharge. Write in pulses continue to be applied as the lateral discharges move across the panel and produce a charge pattern over layer 22. Sustain pulses are also applied between each pair of y-conductors to maintain a display corresponding to the pattern. The sustain and write signals to the y-conductors are applied through gates 41, shift pulse trains to conductors a, b, c through gates 45. A pattern can be shifted vertically by applying the shift pulse trains to the y-conductors through gates 54 and sustain signals to conductors a, b, c through gates 55. Data may be read out using light or current detectors. The number of write drives 52 can be reduced by successively connecting the drivers to groups of y-conductors or each driver successively to two adjacent electrodes using switching arrangements. The shift pulse trains comprise a first igniting pulse V 2  (Fig. 5A, not shown) followed by sustain pulses V 5/2 , positive and negative pulses may be unequal. The pulses to a, b, c, d and y arrays may be out of phase to reduce unwanted discharges. In modifications the walls 13, 23 may be replaced by shield electrodes, strips of low secondary emissive material or the conductors may be periodically widened. Electrode w may be divided into two or more separately energized elements. The insulation on conductors a, b, c, d may be omitted.

Title: Tape recorders
IPC: G11B23/28
Filed: 1970-12-18
Abstract: 1333760 Cassette recorder MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 18 Dec 1970 [18 Dec 1969 19 Dec 1969 (2)] 60319/70 Heading G5R In a cassette tape recorder for educational purposes, e.g., language study, two sensing devices controlling the recording action of the recorder and responsive to indications on the cassette casing are provided, the first responding conventionally to the usual frangible indicator which is broken out to prevent recording on a pre-recorded tape in the cassette and the second responding to an indicator on specially provided instructional cassettes to over-ride the first sensing device and allow a student to record on a track of the tape. The second sensing device can be responsive to a second frangible indicator or can be an electrical device responsive to a conducting patch on the cassette casing, Figs. 7-9 (not shown). If frangible indicator 352 is broken out, sensing device 351 moves in the direction B under the action of spring 362 and prevents operation of record control 355, 354. This action is overridden if the cassette is an instructional cassette provided with a second indicator 357 with a broken out opening as a second sensing device 356 can move into the opening under the action of spring 359, which is stronger than spring 362, and move the first sensing device in the direction A. The recording action of the recorder can be electrically controlled in which case the mechanical sensing devices operate electrical switches, Figs. 7 and 16-20 (not shown). Should recording be attempted in these arrangements a warning is operated in addition to the attempt being blocked.

Title: Process for purifying liquid hydrocyanic acid
Inventor: SCHERHAG BERNHARD
IPC: C01C3/02
Filed: 1968-12-30
Abstract: 1,247,720. Purification of hydrocyanic acid. FARBENFABRIKEN BAYER A.G., and ERDOLCHEMIE G.m.b.H. 30 Dec., 1968 [2 Feb., 1968], No. 61630/68. Heading C1A. Liquid hydrocyanic acid which is contaminated with aliphatic and/or isocyclic hydrocarbons and/or heterocyclic compounds is purified by adding a hydrohalic acid or an oxyacid of sulphur or of phosphorous in concentrated form to the contaminated acid, and separating off the impurities thus leaving the purified liquid hydrocyanic acid. Suitable acids are sulphuric, sulphurous, alksulphonic, aralkyl sulphonic, hydrochloric or ortho, meta or pyro-phosphoric acid. The reaction product between the mineral acid and the impurities is separated from the hydrocyanic acid by distillation over a column or by passing through a tower of active charcoal. In a preferred embodiment, the reaction is carried out in the sump of a continuously operating distillation column, whereby the impurities are continuously removed. The crude cyanic acid is generally produced as a byproduct in ammoxidation processes, e.g. acrylonitrile synthesis.

Title: Electrostatic Printing and Copying
IPC: G03G15/22
Filed: 1978-10-25
Abstract: In a photocopying apparatus an electrostatic latent image is optically created on a precharged photoconductor 13 and transferred to a dielectric member 25 where it is developed with toner particles and the toner image is transferred to plain paper 35. A semiconductor substrate 15 is preferably included in the photoconductor member 11. In a printing apparatus, an electrostatic image is formed on an imaging roller by an ion generator comprising two electrodes separated by a solid dielectric, with a high frequency alternating potential used to create an air gap breakdown in a region at a junction of one of the electrodes and the solid dielectric. A direct current extraction potential applied to the junction electrode is used to extract ions from the discharge thus created. The ion generator and extractor may also be used in photocopier and other applications. The image bearing dielectric member 25 advantageously consists of impregnated anodized aluminium oxide, with high resistivity, and good hardness and smoothness to ensure essentially total transfer of the toned image to a receptor medium. This transfer may be effected with simultaneous image fixing by passing the receptor between the image roller and a backup roller under high pressure. <IMAGE>

Filed: 1980-03-24
Abstract: A reinforced, laminated wood panel comprises sheets of wood 2 e.g. beechwood bonded together by interleaved sheets 3 of fibre-reinforced thermosetting melamine and/or urea resin. Curing is effected at a pressure of between 9 and 25 kg/cm<2>, at 90 DEG C to 130 DEG C for 50 to 65 minutes so that the wood does not become impregnated with the resin and, hence, retains a lower rigidity than the resin sheets. The resultant laminate can be worked with wood working tools but is suitable for use in burglar-proof doors and partitions, and, when compressed at between 20 and 25 kg/cm<2>, is bullet-proof. <IMAGE>
