Title: Improvements in or relating to methods of synchronising scanning oscillators
IPC: H04N5/12
Filed: 1938-12-30
Abstract: 523,457. Valve generating circuits. FERNSEH AKT.-GES. Dec. 30, 1938, No. 37822. Convention date, Dec. 30, 1937. [Classes 40 (iii) and 40 (v)] The fly-back period of an oscillator is stopped when the potential at a point in the circuit is such as to allow current to flow through a biassed diode. In the oscillator shown condenser 20 is charged slowly over resistance 21 and discharged through valve AF7 when pulses from multi-vibrator 1 are fed to grid 19. The saw-tooth potentials produced are fed to valve 26 saw-tooth potentials are produced across anode resistance 15. During the fly-back time the point 16 becomes more and more positive so that eventually diode 28, which is suitably biased by battery 27 becomes conductive and an impulse is applied to generator 1. This impulse causes the valve AF7 to be choked so that the scanning stroke is initiated. Scanning potentials are taken at 24, 25. In the embodiment of Fig. 2 saw-tooth currents are produced in coil 44 by charging condenser 53 over 47, 46, 54 and 55 and discharging it through valve 35 when a synchronizing pulse is received on grid 38. Diode 59 is connected to the cathode of valve 43 and the elements are chosen so that when the cathode potential during fly-back reaches predetermined value, the diode becomes conductive and passes a pulse to grid 37 which chokes valve 35 and initiates the scanning stroke.

Title: System for read out of the coordinates of a matrix type display
IPC: G06F3/038
Filed: 1972-08-21
Abstract: 1407248 Reading displays FUJITSU Ltd 21 Aug 1972 [29 Aug 1971 28 Oct 1971] 38869/72 Heading H3H [Also in Division G4] In order to read out the co-ordinates of a light pen on a matrix type display such as a plasma display panel, the matrix is divided into a number of submatrices each of which is tested in turn by means of read pulses applied to all its co-ordinates, the submatrix in which the light pen is detected then being itself subdivided and the above process repeated until the X-co-ordinate of the light pen has been determined, whereupon the whole process is repeated for the corresponding Y-co-ordinate. In the embodiment of Fig. 2 a 128 Î 128 matrix display 9 is divided into 32 Î 32 blocks, the X, Y co-ordinates being accessed by drivers 8, 8a, Fig. 3E (not shown), fed from a CPU1 via address registers 6, 6a and decoders 7, 7a, Fig. 3D. To determine the X-co-ordinate of the pen, an inhibit register IR, Fig. 3C (not shown), blocks the outputs from flip-flops FF3-FF7 in ADR6 and a counter AC1, Fig. 3A (not shown) causes flip-flops FF1, FF2 to access each block of 32 X-lines in turn (i.e. all lines X1- X32, then all lines X33-X64, and so on); meanwhile an XY change switch 14 causes 6a-8a to access all 128 Y-lines. When the block containing pen 10 is accessed, a signal therefrom is fed to XYS14 via a shaper circuit 15 to halt AC1 and reset IR so that a counter AC2, Fig. 3B (not shown), can operate FF3-FF7 in ADR6 to sequentially access each of the 32 lines in the block (all 128 Y-lines are still accessed): when the X-coordinate is located, ASC15 is again signalled, and XYS14 reverses the X, Y coordinates: 6-8 now access all the X-lines, whereas IR, AC1, AC2, and 6a-8a now access each Y-block in turn to find the Y- coordinate. The last signal from 10 to 15 causes 14 to signal a control unit CU, whereupon CPU extracts the X, Y coordinates from registers 6, 6a. In the embodiment of Figs. 5-7 (not shown), for the determination of each coordinate the display is divided into two halves, the half containing the pen 10 itself being halved, and so on, all the coordinates in a half being accessed simultaneously. A description is given of the read signals necessary to access the matrix in the case of a plasma display panel (Figs. 4, 8, not shown), and also of how information may be written or erased on the display panel using the above apparatus.

Abstract: 1,195,695. Character recognition. MARCONI CO. Ltd. 22 June, 1967 [1 Sept., 1966], No. 38986/66. Heading G4R. Apparatus recognises a character from features (1)-(11) listed below, and interconnections between them, detected by comparing and analysing the signals from successive line scans of the character. Signals from a raster scan of a character are fed to a one-scan-line buffer register and from there, one scan-line at a time, to the first of a series of three further registers holding three consecutive scan-lines respectively. Sets of three corresponding bits from the three further registers are fed in turn to a feature detector, transfer of bits along the chain of three further registers occurring concurrently bit-by-bit. The feature detector outputs are compared with stored reference data to identify the symbol. Feature detector.-The features detected are: (1) start, when a pulse in one scan line does not overlap a pulse on either of the two preceding scan lines, (2) split, when a pulse in one scan line overlaps two pulses in the next following line or two in the next-but-one following line or one in each (the two latter pulses in this last case not overlapping), (3) join, the mirror image of split (i.e. replace "following" by "preceding"), (4) end, the mirror image of start, (5) start/split, i.e. when a pulse complies with both the start and split conditions, (6) join/split, (7) join/end. In (1) to (7), a pulse means a pulse of less than three-quarters of a scan line duration. A socalled long pulse (referred to below) means one which is either longer than three-quarters of a scan line duration or both extends into at least three quarter sections of a scan line and overlaps a long pulse in either the two preceding or the two following scan lines. Further features detected are: (8), (9), (10) the first, middle two, and last quarters of a long pulse respectively, (11) reversal, when overlapping pulses in successive scan lines progress first up the scan lines then down, or vice versa. If a long pulse feature occurs in a series of consecutive scan lines, only that in the first is counted. Vertical character strokes of substantial length are also detected, e.g. to distinguish Y from V. An interconnection occurs if there are overlapping pulses in any two of three successive scan lines.

Abstract: 930,424. Electrically heated furnace pouring spouts. AJAX MAGNETHERMIC CORPORATION. Nov. 14, 1960, No. 39044/60. Class 39 (3). A conduit for molten metal-e.g. a furnace pouring spout or launder-is heated by a resistance coil wound on a refractory tube which fits over the conduit, and has an end flange the thickness of which decreases in the radially outward direction, thereby promoting cooling of the flange, and hence tending to solidify metal escaping through cracks in the conduit before it can pass around the flange to reach the heating coil. The pouring spout, Fig. 5 and 37, Fig. 1, of a submerged channel induction furnace 20 includes refractory lining 48, the refractory heater tube 46 grooved to receive the " Nichrome " (Registered Trade Mark) resistor 47 and flared at the end to form the tapering flange 66, the asbestos lining 45 and refractory cement 67, and the metal casing 41 which is secured via the metal housing 42 to the furnace casing 43. The resistor is in the form of two non-uniformly wound coils, each coil passing round a turn-around pin 56 and terminating at central terminals 60 mounted in sockets in the tube (Figs. 3 and 4, not shown). The heater tube 46 and lining 48 are preferably of silicon nitride bonded silicon carbide. Constructions are described in which only a single non-uniformly wound resistance coil is employed (Figs. 8 to 10, not shown); in which the end flanges extend perpendicularly to the heater tube axis (Figs. 13 and 14, not shown); and in which separate lengths of flanged heater tube are mounted in series to reduce thermal expansion difficulties, and magnesia replaces asbestos as the thermal insulant 45 (Figs. 12 to 15, not shown). The conduit has particular application to the transport of alloys based on aluminium, magnesium, copper, and zinc. In Fig. 1, the pouring spout 37 connects a diecasting machine 38 with the furnace 20, which has gas-tight covers 31 and 35, and an entry port 40 whereby air, nitrogen, or carbon monoxide may be admitted to the furnace chamber under pressure to control the discharge of molten metal through the spout 37.
