Title: Waveform source for television receiver
IPC: H04N3/16
Filed: 1969-03-03
Abstract: 1307212 Sawtooth wave generating circuit; cathode-ray tube circuits RCA CORPORATION 2 March 1970 [3 March 1969] 11212/69 Headings H3T and H4T In a transistorized television vertical deflection circuit utilizing negative feedback via a capacitor 63 from a current sensing resistor 64 in series with the deflection coils 40a, 40b, a capacitor 50 is connected between the resistor and coil to provide a parabolic output voltage for convergence of S correction. The capacitor may also serve to block direct current from the coil and, as it is in the feedback loop, a small value of capacitor may be used to provide the parabolic component without causing non- linearity of the sweep. In Fig. 4 the sawtooth drive is produced by charging the feedback capacitor 63 through amplitude adjusting resistors 61A, 61B and discharging it periodically through the transistors 180, 190 of a complementary type transistor oscillator, the timing of which is controlled by a capacitor 196 and resistor 194. Synchronizing pulses may be fed to the base of transistor 180. The deflection amplifier comprises transistors 80, 90, 100 and complementary output transistors 20, 30 feeding the deflection coils 40A, 40B, connected in series with the D.C. blocking and waveform producing capacitor 50 and current sensing resistor 64. Miller feedback is provided by capacitor 63, waveform shaping feedback via 144 and D.C. stabilizing feedback via 140. In addition feedback capacitors 92 and 107 reduce high frequency amplification and capacitor 109 provides boot-strap feedback.  S-shaping of the defection is effected by a feedback circuit comprising a blocking capacitor 146 and a resistor 147 which serves with capacitor 63 to integrate the feedback voltage. The components 144 and 145 provide phase shift. In Fig. 3 (not shown) the correction circuit is connected in the D.C. feedback path through the resistor 111, 113 equivalent to 140 in Fig. 4. Pin cushion correction is effected by a network 120 comprising (Fig. 3, not shown) the series connection of a saturable action reactor (121) to which a horizontal deflection voltage is applied via terminals H, H<SP>1</SP>, and a correction inductor (123) between the coils, The series connection is tuned by a capacitor (125) to adjust the phase and is shunted by a variable resistor 127 to adjust the amount of correction. Centring of the scan is effected by a resistor 131. Convergence is corrected in the R, G and B coils 170R, 170G and 170B in response to the parabolic voltages developed across capacitor 50. Potentiometers 171 and 177 adjust the R, G line alignment at the top and bottom of the raster, 173, 175 the R, G horizontal alignment at top and bottom and 178, 179 adjust the vertical blue shift at top and bottom.

Title: Character recognition apparatus
IPC: G06V10/20
Filed: 1970-05-06
Abstract: 1310293 Character recognition PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd (Philips Gloeilampenfabricken NV) 6 May 1970 21879/70 Heading G4R Sign recognition utilizes a scanning beam passed circularly across the overall line width of the sign and caused to follow the contour of the sign. The arc or arcs where a given scan circle is over a part of the sign is compared with the last such arc obtained in the previous scan circle for assessing coincidence, the coinciding arcs being counted for use in recognition. No coincidence for one or more scan circles indicates a line end, one coincidence indicates a non-branching line portion and a plurality indicates a branch. Using a light beam for scanning, the photodetector output is gated to one of two delays according to the state of a bi-stable. Each delay has a delay of one scan circle duration and any pulse applied to the delay deletes any pulse already in it. The photodetector output is also ANDed with the two delay outputs in respective gates to supply pulses through an OR gate fed by the two ANDs. When there is no output from the photodetector (ie. when the scan is on the background) presence of a pulse in either of the delays while there is no pulse in the other delay causes the bi-stable to be set so that this "other" delay receives any output from the photodetector. Designs for the delays, using monostables and counters, are disclosed. Each pulse from the OR gate may be used to advance the scan circle along the contour as long as it is present, or preferably a constant duration pulse starting a constant interval after the centre of the pulse from the OR gate is derived from the latter by counting clock pulses as 1 each during the duration of the pulse from the OR gate and as 2 each thereafter until counter capacity is reached, this producing a pulse from a monostable. This pulse, besides advancing the scan circle, also causes the count in a clock-fed counter to be recorded to indicate line direction for use in recognition. The photodetector output may be fed first through a circuit which eliminates short black and white pulses (noise). Advance of the scan circle may be under control of the OR of the two delay outputs directly, as a modification. The scanring may be of an image in an image storage tube.

Title: Time controlled drive devices
IPC: G04C1/06
Filed: 1969-09-17
Abstract: 1320152 Rotary make-and-break switches S DAVALL & SONS Ltd and R W G SOMERVELL 11 Dec 1970 [17 Sept 1969] 45885/69 Heading H1N [Also in Divisions F2 and G1] A time controlled device comprises a drive member 43 with a driving connection to a driven member 46, the movement of which is controlled by an escapement 11 whose driving connection 38, 28 with the driven member 46 is arranged so that the escapement 11 derives driving force from the drive member 43, there being means 39 limiting the driving force applied to the escapement 11.  As shown in Fig. 3 the driving force to the escapement 11 is limited by a torque sensitive brake formed by a helical spring 38 binding at a predetermined torque on a collar 39 secured to a fixed shaft 15. Residual energy stored at the escapement end of the spring 38 continues to drive the escapement but tends to release the brake as it unwinds. However, if energy continues to build up at its other end, the spring 38 will lock upon itself and slipping will occur at a clutch 42 between a power shaft 41 and the drive gear 43 until the energy stored in the spring is sufficiently reduced to unlock the drive. Alternatively, Figs. 1, 2 (not shown) the driving force to the escapement 11 may be limited by the rotation through predetermined angles of switches for starting and stopping an electric motor 25 which winds main springs 13 supplying power to the driven members and to the escapement 11. The device may be used to control the supply of power to any apparatus presenting a variable load but requiring an accurately controlled rotary drive, e.g. a tape recorder, chart recorder, programmer or sequencer.
