Title: Perforated character identifying device
Inventor: ZIPF ALFRED R
IPC: G06V30/224
Filed: 1959-10-02
Abstract: 906,945. Recognizing characters; sensing perforated cards. CUMMINGS-CHICAGO CORPORATION. Oct. 2, 1959, No. 33438/59. Class 106 (1). Apparatus for reading one of a plurality of conventional, visually identifiable indicia, defined by selected perforation stations on a sheet having a relatively large number of such stations, comprises means for passing a signal through all of said selected perforation stations, a plurality of signal-responsive elements corresponding and responding to certain ones only of said perforation stations which include all of a plurality of numerically small groups of stations peculiar to one and only one of said indicia, a plurality of actuators, less in number than the said stations, and means for connecting them to said elements such that an actuator is energized which corresponds to the indicia whose representative group of photocells all receive said signals. The numerals 1-9, 0, Fig. 3, are visually represented by perforations each in one of eighteen positions 30, 32, Fig. 2, and are sensed by projecting a beam of light through the perforations into an array of photo-cells arranged as indicated in Fig. 4 (see also L.H. side of Fig. 1). Although each numeral, Fig. 3, is represented by a number of perforations, a group of three, in positions corresponding to photo-cells is unique to each numeral. Activated photo-cells (e.g. 4, 8 and 16, Fig. 1) fire associated thyratrons and energize relays (R4, R8, R16) which complete a circuit from battery 42 to the appropriate numeral actuator 40 (" 1 " in this example). Modifications described include means for sensing a number of numerals simultaneously by using more than one photo-cell array; two extra holes and corresponding photo-cells wired in series to actuate a sensing prevention mechanism should a misalignment occur; means for advancing the document, including a sprocket and sprocket holes; lucite rods connecting perforations corresponding to the document perforations in a table along which the cards pass, to the photo-cell array, thus eliminating the restrictions placed upon the size of the perforations by the bulk of the photo-cells.

Abstract: 1,164,399. Gas burners. GAS COUNCIL. 25 June, 1968 [20 July, 1967], No. 33458/67. Heading F4T. An aerated gas burner comprises a gas outlet nozzle 1 having two plates 5 fixed on opposite sides thereof, the plates 5 converging towards each other in the direction of flow of gas from the nozzle 1 to form between their nearer edges a slit 9a which is spaced from the nozzle and at which the gas burns with air drawn into the gas stream through gaps between edges of the plates 5 adjacent to the nozzle. As shown, the plates 5 are flat and shaped as major segments of a circle, are equally inclined to the axis of nozzle 1 and converge in a direction away from their straight edges 7. Slit 9a formed between circular edges 6 increases in width from its centre on the axis of the nozzle 1 outwards towards its ends. In use, the burner is normally arranged so that the flow of gas from outlet slit 4 in nozzle 1 is vertically upwards and burns on issuing from slit 9a with a fan-shaped flame. Plates 5 are connected at their bottom corners by straps 8. In another embodiment the plates are shaped as major segments of an ellipse with straight portions adjacent to the burner nozzle. In a further example (not shown) the plates are trapezium-shaped with their longer parallel sides adjacent to the burner nozzle. In a still further example (not shown) the plates have substantially semi-circular portions remote from the nozzle and one plate is flat and fixed parallel to the axis of the burner nozzle, the other plate being bent inwards and having its curved edge portion parallel to the first plate. In another modification (not shown) a pin extends between two plates to improve the mixing of gas and air thereabouts. In yet another modification (not shown) two additional plates are fitted, one to the outer face of each of the two converging plates, the converging plates having holes through them leading to spaces between them and the additional plates so that pilot flames are formed between the upper edges of the two sets of plates to assist in stabilizing the main flame.

Filed: 1948-12-30
Abstract: 659,769. Discharge apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. (General Electric Co.). Dec. 30, 1948, No. 33531. [Class 39 (i)] Apparatus for the acceleration of charged particles, e.g. ions or electrons,, has energizing windings which become magnetically saturable during a portion of the energizing cycle and a capacitance which resonates the windings and by appropriate circuit opening and closing means is precharged and connected to the windings just before the application of the alternating voltage supply thereto. The resonating capacitor 27 is adapted to be connected to the magnetizing windings 25, 26 of the synchrotron excited by input windings 23, 24 the supply to which is controlled by relay 31. It is charged from transformer 40, 41 and rectifier 39, and connected to the windings through a triggered spark gap 37 with a triggering electrode 34. The impulse for electrode 34 is obtained from a grid-controlled gaseous discharge tube 47, via a step-up transformer 52. The grid 49 of this tube is influenced by a peaking transformer 45 which is energized by a phase shifter 44. The coils 55, 56 of circuit-breakers 31, 36 are energized by windings 23, 24, the voltages being induced by the flux through coils 25, 26. The capacitor 27 is charged by closing switches 38, 41 and the starting switch 46. The tube 49 is fired at a time determined by the phase-shifter and discharges condenser 53 which has been charged from a source B. An appropriate voltage is induced on triggering electrode 34, so that an arc extends between electrodes 32, 33 and capacitor 27 is discharged through windings 25, 26, causing the excitation circuit to oscillate. Closure of circuit breakers 31, 36 simultaneously connects the voltage source to coils 23, 24 and shorts the spark gap so that its arc is extinguished. Proper phasing of the spark discharge avoids troublesome transient voltages. The switching in of the electron gun and of the electrodes 14, 15 of the synchrotron is accomplished as in Specification 574,812 by a magnetic peaking strip 60 controlling these devices through appropriate supply and delay devices.

Title: Improvements in or relating to signal reproducing systems
IPC: G11B15/14
Filed: 1963-08-29
Abstract: 1,003,496. Local circuits for magnetic playback heads. AMPEX CORPORATION. Aug. 29, 1963 [Oct. 1, 1962], No. 34281/63. Heading G5R. A circuit for combining successive frequency - modulated signals from a plurality of magnetic playback heads comprises means for demodulating the signals from individual heads and means for sequentially combining the demodulated signals to provide a single output signal. The apparatus shown in Fig. 1 may be provided with inputs from an amplitude modulated signal source 11, a pulse code modulated signal source 12, and a frequency modulated signal source 13. The inputs are translated to specific frequency bands in units 20-22, combined in unit 30 and applied to a frequency modulator 31 feeding a recording playback head system 32 which may comprise a drum carrying four heads and rotating transversely of a moving tape 33. When playing back the signals, the signals from one pair of opposite heads pass to unit 41 and the signals from the other pair to unit 42. Units 41 and 42 in conjunction with timing pulses from a timing unit 50 form gating circuits to close the channels when the respective heads are not in contact with the tape. Signals passing through the gates 41 and 42 are demodulated in units 46 and 48 respectively, which may be discriminators or pulse counters, and are recombined in a switching circuit 52 before passing to circuit 53 which recovers the original AM, PCM and FM signals. A level control circuit 54 samples the signal levels at the demodulators 46 and 48 and adjusts the bias levels so that they are identical when switching occurs. The timing pulses controlling the switching unit 52, the level control circuit 54 and the units 41 and 42 are produced by a unit 50 responsive to head drum position. The unit 50 may be further controlled by timing pulses recorded by one of the heads on the tape, by synchronizing signals contained within the recorded signal information (e.g. so that switching occurs during the blanking intervals of a television recording), or by an external timer. In a modification, Figs. 2 and 3 (not shown), a second head drum is provided longitudinally displaced from the first and with its heads offset by 45 degrees from those of the first. The signals from the second drum are processed in the same manner in further circuits under the control of a common timing unit.
