Title: Reader
IPC: G06K11/00
Filed: 1961-05-26
Abstract: 958,994. Electric selective signalling; sensing record cards. RADIO CORPORATION OF AMERICA. May 26,1961 [June 6, 1960], No. 19156/61. Headings G4H and G4M. Apparatus for measuring a co-ordinate y of a point on a graph 14 Fig. 2 comprises a bundle of light-transmitting-fibres 10, Fig. 1 the individual fibres being arranged in a line parallel to the y direction at the end 12 adjacent the graph 14, and being arranged on a circle at the other end 16 so that the fibres may be scanned in succession by means of a rotating disc 28 having a single hole 30 at the same radius as the ends of the fibres. A further light-transmitting channel 50 extends from hole 30 to photocell 54. Disc 28 has further holes 44,42 for generating a start pulse and clock pulses. The apparatus may be used to determine the average ordinates of points on a curve such as that shown in Fig. 2, having a thickness 2c. At the start of a measurement, a pulse from photocell 58 sets flip-flop 70 Fig. 5 and opens gate 72, allowing clock pulses from photocell 62 to reach counter 80. Pulses from photocell 54 are supplied to an inverter 76 giving an output train of pulses which is out of phase with the clock pulses train, and gate 74 therefore produces no output pulse at this stage. When hole 30 registers with the first fibre which is located over the curve, no pulse is produced, the output of inverter remains "high", and clock pulses pass through gate 74, the first of these pulses resetting flip-flop 70 and closing gate 72. When the scan passes beyond the curve, photocell 54 again produces pulses and no further clock pulses pass through gate 74. The output of gate 74 is connected to a scale-of-two flip-flop 77 and thus counter 80 receives a first train of pulses representing the distance to the lower edge of the curve from gate 72 and a second train of pulses representing half the thickness of the curve c from flip-flop 77, the total count representing the desired co-ordinate y. A series of such measurements may be made by moving the graph to the left between or during scans. Similar apparatus is used for sensing a punched card 152, Fig. 11. A bundle of light-transmitting fibres is constructed so that at one end the fibres are arranged in columns 154, 156 adjacent the card, and at the other end the fibres are arranged in a circle 150. The ends of the fibres in the circle 150 are scanned in turn by means of a rotating disc having an aperture which connects with a stationary photocell through a light-transmitting channel. The columns 154,156 of fibre ends are preferably offset as indicated by lines 158 to compensate for movement of the card while the columns are scanned in turn.

Abstract: 677,536. High-frequency discharge apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 20, 1949 [July 20, 1948], No. 19160/49. Class 39 (i). An electron beam tube comprising two parallel conductors 1, 2 between which an electrostatic field is established and wherein a constant magnetic field is applied perpendicular to the electric field and the direction of propagation of the beam, the two conductors constituting a retardation line in which is excited an electromagnetic wave whose speed of propagation is substantially the same as the speed of the beam, whereby the wave is amplified by interaction with the beam, is characterized in that a plurality ot cathodes 8 are distributed along the retardation line at intervals whereby the beam of each subsequent cathode interacts with the wave when the amplification due to the interaction of the beam of the previous cathode no longer increases sufficiently; preferably the distances between successive cathodes diminish from the input to the output end of the tube. In. Fig. 1 the conductor 1 is provided with a plurality of pins 3 to slow down the wave and the line is tapered at each end to match it to the input and output which may be capacitative connections to the Lecher lines 12. The cathodes 8 are in the plane of conductor 2 which may be at cathode potential but is preferably negative with respect to the cathodes. The magnetic field is perpendicular to the plane of the drawing. In the tube shown in cross-section in Fig. 4 the conductor 1 is a flattened helix connected at each end to a coaxial line 15; the cathodes 8 are arranged between the helix 1 and the planar conductor 2. Conductors 1 and 2 are fixed in ceramic members 14 which may be of aluminium or beryllium oxide. At the end of the line a copper block is provided to collect the electrons and it may be cooled with water or compressed air. The electromagnetic wave may be partly reflected at the cathodes 8 and to correct this obstacles which are preferably in the form of fins 22, Fig. 5, may be arranged in front of the cathodes which may be provided with focusing electrodes 23. The lower conductor 2 may be provided with fins 3 to assist in slowing down the wave, Fig. 6 (not shown). The Specification as open to inspection under Sect. 91, comprises also tubes with a single cathode and a tube using an electron gun to fire a beam down the delay line. In Fig. 10 (Cancelled), the upper conductor 1 comprises a metal sheet bent so that the medial portion supports the retarding fins 3 whilst the spaces between the fins are coupled to one another by the capacitors 24, 25 formed by the ends of the fins and a fold of the metal sheet; the thickness of this capacitative portion may be varied by compression and the phase velocity of the wave can thus be varied. Arrangements in which the spacing, dimensions, and contour of the fins are varied at each end of the line for matching purposes are also described. This subject-matter does not appear in the Specification as accepted.
