Title: Electron beam positioning apparatus
IPC: G11C11/23
Filed: 1957-04-26
Abstract: 836,235. Electric selective signalling apparatus. WESTERN ELECTRIC CO. Inc. April 26, 1957 [April 27, 1956], No. 13350/57. Class 40 (1). [Also in Groups XIX and XXXV] A digital-to-analogue converter consists of a cathode-ray tube with a perforated target containing rows of binary digital coded numbers in which the beam is deflected until the row of numbers selected corresponds to the coded input address. There is an additional control of fine positioning of the beam with respect to the selected row of apertures. The resultant control voltage necessary to effect the deflection represents the analogue output and is used to control one axis of the beam deflection system of an information storage tube. The second axis is controlled by a similar arrangement. In one embodiment, for a 5-digit code, the input address, applied in parallel form to a register 17, is converted to an analogue voltage at 18 and after amplification at 19 applied to the deflection plates 15 of the cathode-ray tube 10 so as to position the beam vertically on the code plate 13. The digital output obtained from the targets 26 ... 30 by scanning the beam horizontally is compared at 31, Fig. 2 (not shown), with the original address and any error, amplified at 32, is applied to the amplifier 19 to move the beam to the correct position on the plate 13. Anadditional quantizing set of apertures 30 provide an output for centralizing the beam with respect to the selected row of code apertures. In a second embodiment, Fig. 3, a three-digit code address applied to a register 17 is subtracted at 49 from the output of the targets 27 ... 29 of the coding tube. If the two code signals are not in agreement, then an output is produced in respect of each incorrect digit, and this output controls the appropriate one of 3 current generators 43 ... 45. The generators are " weighted " in accordance with the numerical significance of the digit column with which each one is associated, and the sum of the outputs of the current generators is applied to the deflector plates 15 to position the beam. A quantizing control is again obtained from apertures 26. Specifications 836,234, 836,236 and 836,237 are referred to.

Filed: 1971-05-07
Abstract: 1351844 EHT supplies RCA CORPORATION 7 May 1971 [11 May 1970 4 Jan 1971 29 March 1971] 13635/71 Heading H2F [Also in Divisions H3-H5] In a combined deflection circuit and EHT supply for a TV receiver, a protection circuit is included to reduce the line frequency in the event of excessive EHT voltage or in the presence of both positive and negative excursions of flyback pulses. The invention thus protects the phosphor on the cathode-ray tube from high energy electrons and reduces possible X-ray hazard. Fig. 3 shows a circuit for supplying line deflection currents to coils 661 and EHT voltage from a multiplier 901 and is of the type described in Specification 1,260,375. Failure of damping diode 621 results in a voltage across capacitor 671 having both positive and negative excursions. The negative excursion will cause diode 931 to conduct, reducing the voltage at the junction of resistors 261 and 281 and reducing the frequency of the line oscillator 161 so as to make the picture un-viewable and to reduce the excessive EHT voltage from multiplier 901. An EHT voltage regulator is included comprising a saturable reactor 108. Failure of the regulator will result in excessive positive voltage across capacitor 671 which turns on transistor 150, normally biased off by Zener diode 152, so as to reduce the frequency of line oscillator 161. In Fig. 1 (not shown) the voltage regulator comprising saturable reactor 108 is omitted and the protection circuit merely comprises a diode (35) connected between the S-shaping capacitor 641 and the gate of thyristor 681 and operates by becoming conductive if the voltage across capacitor 641 exhibits a negative excursion so as to cut off the gate drive of thyristor 681 so that the line deflection frequency and EHT voltages are reduced. Alternatively as in Fig. 2, an auxiliary winding 50s on the EHT transformer is coupled to a peak detector arranged so that in the event of failure of the damping diode 621 capacitor 61 will charge excessively positively, breaking down Zener diode 60 and so providing a continuous gate drive to thyristor 681. This action opens a breaker in the B + supply.
