Title: Improvements in or relating to recording blanks for electric recording in facsimile telegraphy
IPC: H04N1/23
Filed: 1954-05-21
Abstract: 755,566. Copying-telegraphy. CREED & CO., Ltd. May 21, 1954 [May 26, 1953], No. 15076/54. Class 40 (3). [Also in Groups VIII, XVI and XIX] An electro-sensitive recording blank for copying-telegraphy comprises a non-conductive base sheet carrying an adherent electrically-conducting coating of finely-divided carbon dispersed in a water-soluble binder, the coating being such as to have a high resistance surface stratum consisting mainly of a surface concentration of a varnish or lacquer resin having intermingled therewith some of the water-soluble binder and carbon, the stratum having thereon a thin adherent surface coating of substance of a character to be disintegrated in elemental areas in response to electrical marking currents. The high resistance surface stratum is due to the surface concentration of the resin phase of a resin solution emulsified in an aqueous solution of the binder in which the carbon is dispersed. The base sheet 70 of a suitable paper is coated with a layer of a mixture of an emulsified resin solution and a carbon dispersion in a watersoluble binder, preferably comprising casein, the water being absorbed by the paper sheet 70 and partially evaporated at the outer surface of the coating to form a layer 71 including the conductive carbon and a layer 72 containing mainly the resin, but including a small amount of carbon. The surface coating 73 of relatively high electrical resistance may comprise cuprous or lead thiocyanate, zinc sulphide, lead thiosulphate or an oxide of lead, titanium or zinc. The water-soluble binder may comprise polyvinyl alcohol, starch, or glue, and the resin may be an air-drying styrenated alkyd resin dissolved in toluol. Other resins include vinyls, modified resin esters, ethyl cellulose, dammar or rosin, and examples of the emulsifying agent are the oleate or stearate of ammonia or the oleate of morpholine. If the blank is to be used for lithographic off-set printing, the carbon layer may be made water-repellent and ink-receptive by adding to the mixture a small amount of water-soluble silicone, such as sodium methyl siliconate. Specification 660,029 is referred to.

Filed: 1950-06-19
Abstract: 707,228. Coating with metals. LONG, A., TAYLOR, F. N., and BLACKLOCK, A. June 18, 1951 [June 19, 1950], No. 15285/50. Class 82 (2) [Also in Group XXII] A method of applying metal to a surface for welding or coating it comprises supplying powdered metal and combustible gases to a nozzle whereby the powdered metal is simultaneously fused in the gas flame and combined with the fused surface to which the flame is applied, the powdered metal being drawn into the gas stream by an injector effect created by the passage of said gases to the nozzle. Apparatus according to the invention comprises a body 10 provided with nipples 11 and 12 for oxygen and acetylene respectively, valves 13 and 14 for controlling the gas mixture and a pipe 15 for receiving an adaptor 16. The pipe 15 is provided with a mixing nozzle 18 which is located within a conical chamber 19 in the adaptor 16. The narrow end of the chamber communicates with a pipe 22 leading to a nozzle 17. A hopper 30 containing powdered metal is supported by a discharge pipe 31 on a coupling member 32 having a central core 35 and nipples 34 and 33 are at each end. Extending into the core 35 is a tubular lining 36 mounted in a gland 37 and provided with a knurled head 38 whereby it can be turned in the member 32. The inner end of the lining 36 is provided with several different size'holes 39 capable of registering with the pipe 31 for regulating the powder feed from the hopper. The end 41 of the lining opens to the atmosphere and the inner end to the core 35 which communicates with a pipe 40 leading to the chamber 19 in the adaptor 16. In operation the lining 36 is adjusted. to bring the desired hole 39 into register with the pipe 31 from the hopper. The oxygen and acetylene valves 13 and 14 respectively are opened whereupon mixed oxy-acetylene gas issues from the nozzle 18 and creates a partial vacuum in the chamber 19 which draws air into the lining 36 and induces a flow of powdered metal from the hopper into the oxyacetylene gas stream which is ignited at the nozzle 17. The nozzle 17 is held within an inch of the surface to be welded or coated the metal powder and the surface being simultaneously fused and combined. A number of separately controlled hoppers may be provided for supplying a number of different metal powders so as to provide any desired mixture of metal powders in the gas stream.

Patent GB-1491919-A (GB)
Title: Display apparatus
IPC: G09G3/28
Filed: 1975-04-14
Abstract: 1491919 Matrix displays WESTERN ELECTRIC CO Inc 14 April 1975 [15 April 1974] 15318/75 Heading G5C Gas discharge display apparatus includes a plurality of display sites, means for selectively addressing the sites, one or more radiation sources activatable to facilitate gas discharge at the sites and means for activating the sources at a time # relative to the time of addressing a selected site which is dependent on the position of that site relative to the sources. This variation of time # overcomes problems caused by sites in the centre of the panel requiring a higher write voltage V b  than those at the panel edge which are adjacent the sources (Fig. 4). The provision of sufficient voltage for centre sites can result in spurious operation of non- selected sites at the panel edge. However the required write voltage varies with the delay time # hence varying # allows a constant voltage V b0  to be used to write all sites. The time # is vaned in ST steps by applying a source actuating pulse earlier either by widening the pulse or shifting it. The sources comprising keep alive discharge sites surrounding the display sites are continuously energized by sustain signals synchronized with those of the display sites but of a higher voltage. The display sites may be divided into vertical bands and the value of # chosen according to the band in which a selected site falls. Address signals in binary form are, convenient for determining # in incremental values using a circuit including a counter (803), Fig. 9 (not shown). When elongated pulses produce unbalanced wall charges the sustain pulses are shifted using delay devices (955), Fig. 12 (not shown). Since the display sites are surrounded by keep alive sites it is preferable to use the distance of an addressed site from the nearest keep alive site, to determine #. This is done by comparing the X and Y addresses. The majority of keep alive sites are driven by a keep alive sustain signal on one electrode and a display site sustain signal on the other. The time shift # need only occur on one pulse of the sustain signal, e.g. applied by the Y conductor. The keep alive sustain signal on Y conductors is chosen and no alteration of display site sustain signal occurs. The sustain pulses of sites on the vertical (Y direction) sides of the panel are thus modified but not those on the horizontal sides. Any change in the Y signals to those sites involves a similar undesirable change in display site signals. This problem is overcome by applying positive and negative pulses to the X conductors of the keep alive sites which combine with the unmodified Y signal to give a pulse with the desired delay #. Panels with polar and figure of eight electrode arrays and sinusoidal keep alive sustain pulses are referred to.
