Title: Improvements in or relating to fluorescent screens
IPC: G21K4/00
Filed: 1925-01-31
Abstract: 228,568. Kodak, Ltd., (Assignees of Sheppard, S. E., and Eberlin. L. W.) Feb. 1, 1924, [Convention date]. Fluorescent screens. - In a screen comprising an active layer containing a fluorescent salt, a rear supporting layer, and a front protecting layer of cellulosic material, the protective layer is rendered matt by incorporating therein a lightdiffusing material. The screen may be produced by coating in succession upon a polished surface the protecting layer, the active layer, and a layer of material containing metallic particles in suspension, the finished screen being stripped from the polished surface. A fluorescent salt, such as calcium tungstate, may be used as the light-diffusing ingredient, and its proportion by weight to the cellulosic binder should be less than 50 per cent. The binding-agent in the active layer is preferably not greater than 5 per cent of the weight of the fluorescent salt.

Title: Test signal generator
IPC: H04N17/04
Filed: 1970-01-21
Abstract: 1287195 Television RCA CORPORATION 21 Jan 1970 [29 Jan 1970] 2881/70 Heading H4F Apparatus for generating test patterns, e.g. for testing electron beam convergence, at a television receiver 21 which is responsive to amplitude modulated signals at terminals AA<SP>1</SP> from the terminals BB<SP>1</SP> of an antenna 65 comprises a switch portion 67, 69 interposed in use between AA<SP>1</SP> and BB<SP>1</SP> so that normal television signals may still be received, and a generator 17, 23, 25, 27, 43, 49, 55 synchronized with the receiver horizontal sync. signals from a line 19 for producing pulses which bear a predetermined relationship to the receiver horizontal and vertical sync. signals and which cause a diode 57 of the switch 67, 69 to conduct and so provide a momentary low impedance across terminals AA<SP>1</SP>. The absence of signal is seen by the receiver as 100% carrier modulation (maximum white being equal to 85% modulation) and so corresponding bright spots are produced on the display tube 71 even when the brightness control 75 is adjusted to exclude the incoming television image. As shown, the horizontal sync. pulses at frequency H from line 19, which may be simply a wire adjacent the receiver 21 and near the horizontal deflection coils 77, are used to synchronize Colpitts oscillators 23 and 25 operating at frequencies of 2H and 12H respectively. The 2H oscillation is divided by thirtyfive in a relaxation oscillator 29 (35 is 1/15 of 525 lines) and fed to an AND gate 43 which also receives the 12H oscillation and thereby produces pulses forming, in this ease, a pattern of 15 equally spaced rows each with 12 equally spaced dots. The oscillator 27 includes a capacitor 31 which charges via resistors 35, 37, 33 until the potential at the emitter of a unijunction transistor 29 is such that the output from oscillator 23 causes it to conduct and discharge capacitor 31 via resistors 33, 39. Thus potentiometers 35 and 37 provide coarse and fine adjustment of the diversion ratio (or frequency of the output), and the output pulse length is determined by the setting of potentiometer 33.

Title: Automatic road traffic control
IPC: G08G1/08
Filed: 1966-01-21
Abstract: 1,126,934. Road traffic signals. INTERNATIONAL STANDARD ELECTRIC CORP. 21 Jan., 1966 [22 Jan., 1965], No. 2888/66. Heading G4Q. Traffic at a cross-roads is controlled by a programme selected from a plurality of predetermined programmes in accordance with traffic counts made in each approach lane for a pre-determined period. The output of counting devices 1, Fig. 2, are converted to analogue signals in converters 2 and fed to an adaptive memory storage matrix 3 which marks the rows of the matrix which most nearly correspond to the input. The output of the matrix corresponds to the required programme and is converted in unit 4 into digital form and fed to a control circuit 6 which also receives inputs from the converters 2 via a control element 12 and analogue-to-digital converter 5. The control circuit provides an output switching programme which is entered into store 7 and compared with the current programme in store 8; if there is a significant difference the gate 10 is opened to allow the new programme to replace the old in store 8. The counting cycle is repeated regularly, e.g. every 3 minutes, so that the optimum programme is kept up to date. If the maximum cycling period is exceeded, an output 13 from the control circuit 6 to the control element 12 reduces all the input signals in the same ratio.

Title: Improvements in or relating to the production of hollow articles consisting of or comprising thermoplastic resins
IPC: B29C70/32
Filed: 1944-02-21
Abstract: <PICT:0585395/III/1> Powdered organic thermoplastic material, e.g., synthetic resin or cellulose acetate, is introduced into a hollow body, the body is rotated to spread the powder over its interior surface, and then heat is applied, whilst the body is still rotating, to fuse the powder and form a coherent layer on the said surface. The layer is allowed to cool.  The body may be a metal tube, and may be spun fast enough to compact the resin &c. and accelerate the escape of bubbles therefrom.  The resin layer may be circular or elliptical in cross-section, or otherwise shaped as by the use of insertions in the tube.  The tube may be rotated about more than one axis. When polyvinyl chloride powder is used, a basic stabilizer should be present, to neutralize liberated hydrochloric acid. Polyamides oxidize at elevated temperatures, and may be fused in an inert atmosphere.  Polystyrene may be used, and polythenes plasticized with polyisobutylene are particularly suitable.  The resin may be reinforced by wire mesh or sheets of coarse-fibred material such as asbestos, glass or cellulose fabric by introducing these materials into the tube before the resin has solidified.  In an example, asbestos paper is put into the tube before the resin powder is put in.  A metal tube 1 may be lined with resin 5, loss of resin being prevented by rings 2 spaced from flanges 3 by rings 4.

Title: Measurement of temperature distribution on a solid surface
IPC: G01K11/20
Filed: 1950-02-13
Abstract: 675,043. Luminescent materials and applications. EASTMAN KODAK CO. Feb. 13, 1950 [Feb. 11, 1949], No. 3625/50. Class 39 (i). A method for rendering visible the heat distribution on the surface of a solid body which comprises laying on or applying to the surfaces or parts thereof a thin uniform layer or thin uniform patches of a phosphor whose luminescent intensity when uniformly illuminated by exciting radiation is above nil and below the maximum obtainable from the phosphor at its optimum temperature. In Fig. 1, the condensing chamber 11 of a still is coated with a fluorescent phosphor 12 which is illuminated by ultra-violet light from a source 17. Comparison is made with a monitor disc 18 carrying the phosphor, or the layer may have been calibrated previously. Photographic records of brightness may be taken. This method may also be applied to internal combustion engines to determine cooling fin design. Small patches of phosphor, e.g. of phosphorescent tape, may be applied to very large surfaces, being accompanied each by a patch of a temperature insensitive phosphor. In further modifications an endless band coated with phosphor is in temporary contact with a moving sheet of material, e.g. rock wool, the temperature distribution of which determines faults, and when the phosphor band has been brought to the temperature of the sheet, it is illuminated with U.V. light and the luminescent brightness recorded by a photo-cell. Masks may be used in Fig. 3, where the phosphorescent property is utilized, the phosphor band 43 is illuminated with U.V. light from lamp 44, moves into contact with the hot sheet 30 of rock wool, and its phosphorescent brightness recorded at photo-cell 45 and fed to an amplifier 46 which actuates an inking device 47 to indicate a fault. A further modification utilizes fluorescence only, the lamp and photo-cell being situated at a point on the band just after leaving contact with the moving sheet. Graphs are included showing the relationship between temperature and brightness of a large number of phosphors which can be used. The examples give phosphors with positive or negative coefficients and include tungstates of strontium, lithium, sodium, zinc, barium, cadmium, magnesium, and calcium, the latter activated with manganese; molybdates of strontium, zinc, cadmium and lead or a mixture of the latter two ; cobalt borate; and sulphides or selenides of zinc and/or cadmium with silver, nickel or copper as activators. Temperatures of response range from - 200‹ C. to over 400‹ C. Specification 675,042 is referred to.
