Title: Character reader
IPC: G06V30/224
Filed: 1964-12-07
Abstract: 1,021,907. Automatic character readers. SPERRY RAND CORPORATION. Dec. 7, 1964 [Dec. 30, 1963], No. 49644/64. Heading G4R.  Characters of the kind shown which are formed of a series of vertical strokes the leading edges of which are spaced either ''long'' or  " short " distances apart according to a code by which the character is identified, are read by sensing the strokes, using the leading edge of each in turn to initiate a ramp voltage which is reset when the following leading edge signal appears, the successive values reached by the ramp voltage being stored and a proportion of the highest used as threshold level whereby the long space signals are distinguished from the short space signals. This method of reading compensates both for variations in speed of movement of the document and for variations in thickness of the stroke lines. In the apparatus described the character is sensed magnetically. The waveform generated is applied to a digitizer adapted to produce signals representing the seven successive strokes. This consists of a 90- degree phase-shifter followed by a zero-crossing detector. The pulses from the zero-crossing detector pass to a multivibrator which blanks out signals from spurious marks between strokes. The output of the multivibrator is applied to the ramp generator and to a stroke counter which produces six distributing pulses for the six successive ramp voltages and an end-of-character signal from the seventh stroke. The six ramp voltages which are stored on six capacitors, are applied through an Or gate to a circuit which provides a certain percentage of the highest voltage to act as a threshold voltage. The end-of-character signal gates this voltage to the threshold circuit and the stored voltages exceeding this level give outputs. These correspond to the two long spaces, An error circuit responds if more or less than two outputs are produced. The combinational signals, two leads marked out of six, are recorded to indicate on one of fifteen leads the character read. A false start by the stroke counter, due to a spurious mark proceding the character is guarded against by connecting the output of the ramp generator to a threshold Schmitt trigger which responds when the signal approaches its maximum. This resets the stroke counter. In case the first stroke should be detected as the counter is being reset the first stroke, under these conditions, is stored into a flip-flop and entered in the counter later. The end of character signal from the stroke counter sets a monostable circuit serving to disable the system for a fixed period between characters. This prevents spurious response to ink splatter in the greater part of the inter-character gap.

Title: Squelch circuit
IPC: H04N5/93
Filed: 1974-11-18
Abstract: 1531214 Recording; defect elimination RCA CORPORATION 23 Oct 1975 [18 Nov 1974] 49924/74 Heading H4F In a video disc player, including a pick-up which recovers from the disc carrier frequency modulated by the video signal, means are provided to detect when the frequency of the carrier falls outside a predetermined range, to substitute a delayed video signal during these times and to inhibit the development of the video signal when a defect has been detected for more than a predetermined time. As described the video signal from pick up circuits 21 is demodulated and a defect detector 61 produces a pulse during periods when the carrier falls outside a predetermined range. For short duration defects a one line delayed video signal derived from comb filter 51 is substituted for the non-delayed signal by switch 39 under control of generator 67. The defect signal is lengthened (by 3 microsecs) by pulse stretcher 62 and passed to a squelch control signal generator which produces an output only when the defect signal has been present for a predetermined time (50 ms) which is long compared to one line interval, the time being determined by both the charge rate of capacitor 77 and the level at which diode 78 becomes forward biassed, and continues to produce an output for a considerable time (preferably ls) after the end of the defect pulse which time is determined by the time constants of RL combinations after diode 78. The squelch signal is applied to adder 57 and to limiter 25 to inhibit the output of audio and video signals. Interference from noise is particularly troublesome when the stylus is raised from the disc surface and at these times the squelch signal generator is controlled directly from the solenoids controlling stylus movement, see Specfication 1,531,215 (Division G5). Other parts of the circuit of Fig. 2 are wellknown e.g. the phase locked loop 41, 43, 45, 47, 49 controlling the oscillator 43 to produce correct frequency signals for changing the subcarrier frequency of the recorded video signal to one compatible with a conventional TV display and clamp circuit 55 which restores the D.C. component of the luminance signal derived from comb filter 51.

Abstract: In the formation of a thin rod of semi-conductor material having a substantially constant diameter of less than 5 mm by the relative passage of an inductively heated molten zone 66 (Fig. 1, not shown) through a thicker rod 12 with pulling together with rotation by means 26, the distance d between the solidifying interface 68 of the molten zone and an imaginary plane a through induction coil 62 is maintained constant by control of the rate of stretching.  An image of a portion of the surface of the rod about the solidifying interface is projected on to a variable resistance photoelectric cell 72 and variation of the light intensity from a particular range causes passage of a signal to motor 52 for increasing or decreasing the rate of pulling.  The image may be of an inside (Fig. 2, not shown) or outside (Fig. 4, not shown) surface portion.  Two photoelectric cells in series (Fig. 3, not shown), for both inside and outside portions, may be employed. The use of an image of an outside surface portion about the solidifying interface gives additional control over the diameter of the zone-melted rod.

Title: Improvements in and relating to transmission and receiving systems
IPC: H04L7/06
Filed: 1963-12-30
Abstract: 995,120. Telegraphs; transistor circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 30, 1963 [Jan. 2, 1963], No. 51136/63. Headings H3T and H4P. In a data transmission system employing frequency shift keying the space frequency which is transmitted between successive messages is amplitude modulated, so that at the receiver a clock pulse generator, which clocks the received data for regeneration, is kept in phase during both the message transmission and the long space transmission. At the receiver, Fig. 2, the f.m. data is demodulated 7, 8 to provide a double current signal which is fed to regenerator 9. Differentiator 10 provides the mark-space transitions, these triggering 1 bit flip-flop 12. The trailing edges of the flip-flop output cause filter 13 to ring at bit frequency to give clock pulses which, after limiting, are used to sample the received data at 9. When the a.m. long space frequency is received, integrator 24 attains a value at which it enables gate 22. The a.m. signal which as described is modulated at quarter bit frequency is demodulated at 17, 18 and passes via gate 22 to differentiator 23, whose output triggers flip-flop 12, so that the clock pulses are maintained during the long space. Circuitry.-At the transmitter, to derive the amplitude modulated long space signal, bit frequency clock pulses are fed to a dividing circuit 30, Fig. 3, which has a circuit in its collector tuned to quarter bit rate. Positive feed-back ensures that only one in four of the input clock pulses passes through this stage. The pulses are amplified at 31, 33 and fed to transistor 34 which has negative feed-back as shown. This effectively varies the output resistance of this stage which is used to amplitude modulate the output of the frequency modulator when the long space signal is extant. A blocking signal is applied at 61 when a message is being transmitted. At the receiver, Fig. 4, the output of the amplitude demodulator passes to amplifier 41, which is sharply tuned to quarter bit frequency, whose output passes via limiter 43, 44 to differentiator 49, 50 which feeds the flip-flop. The limiter output is blocked during message reception by conducting transistor 47. During the long space, the steady output from the discriminator charges capacitor 58, thereby switching off transistor 47.
