Title: Convergence system for a color picture tube
IPC: H04N9/28
Filed: 1968-06-19
Abstract: 1,219,637. Cathode-ray tube circuits. SONY CORP. 19 June, 1968 [22 June, 1967], No. 29126/68. Heading H4T. In a colour television receiver utilizing a single-gun three-beam picture reproducing tube 10, Fig. 1, in which electron lens means L<SP>1</SP>, L act on the beams to direct one (E G ) along the tube axis and to cause the other two (B B ), (B R ) to diverge so that they pass between respective pairs of deflecting plates P<SP>1</SP>, Q<SP>1</SP> and P, Q, static convergence of the three beams is effected by a deflecting voltage Vc applied between the plates of each pair and generated by rectifying by diode 30 the voltage developed across the secondary winding of a transformer 23 the primary of which is connected via an adjustable impedance 25 to a winding 24 on the line (horizontal) output transformer 21. The transformer 23 provides isolation between the high voltage V Q  and the impedance 25 so that manual adjustment of the latter may be effected safely. The converged beams then pass between adjacent grid wires gp of a grid Gp and impinge on appropriate ones of a repeating series of vertically extending colour strips on the tube screen S and to ensure convergence throughout each horizontal scan a dynamic convergence correction voltage V<SP>1</SP>C having a parabolic waveform is generated by the integrating effect of an inductor 27 and capacitors 28 and 31 and combined with the static convergence correction voltage Vc so that the voltage between the deflecting plates = Vc+ Vc<SP>1</SP>. This voltage " stands-on " a high voltage V Q , produced by rectifying in circuit 22 the voltage across a further winding 13 on transformer 21 and provides a voltage Vp = V Q + Vc+Vc<SP>1</SP> which is connected to the deflecting plates P, P<SP>1</SP> the electron lens elements G 3  and G 5  and to the screen S by connection means (not shown) internal of the tube. An advantage of the arrangement is that when the voltage Vp varies due to tube current variations caused by variations in picture brightness the ratio Vc/Vp is unaltered so that the convergence remains unchanged. Another advantage is that since the high anode voltage Vp is derived from the sum of (two) lower voltages insulation requirements are not so stringent. Instead of being connected in series with the primary of transformer 23 the adjustable impedance 25 may be connected in shunt therewith (Fig. 3A not shown) and instead of an adjustable impedance a multi-contact switch connected-to taps on the primary winding may be employed (Fig. 3B, not shown). For the production of static convergence only, the inductor 27 and the capacitor 28 are omitted (Fig. 3C, not shown).

Title: Improvements relating to pulse radar
Inventor: EVANS NOROL THEODORE
IPC: G01S13/87
Filed: 1968-06-19
Abstract: 1,220,704. Pulse radar. HUGHES AIRORAPT CO. 19 June, 1968 [19 June, 1967], No. 29152/68. Heading H4D. In a radar receiver the video returns are amplitude-quantized, into a multilevel code consisting of several bits, for each range "bin" interval, and are utilized to update the count in a multibit counter associated with each range bin; the count for each radar sweep, as well as the counts in preceding sweeps, and/or adjacent channels in a stacked beam radar, are used to generate leading and trailing edge signals for target azimuth detection. In the embodiment a 3-bit code is utilized in the quantization of amplitude e.g., the code 001, representing an amplitude of one, corresponds to a peak video level X of between 2À8 dB and 5À8 dB above r.m.s. noise: the 3-bit code utilized is designed to reduce false alarms due to noise. A threshold count of eight is selected for leading edge detection of a target and when the leading edge is detected the counter logic is modified, the counter is reset to zero, and when a count of eight is reached again a trailing edge signal is generated, azimuth then being computed (by known means not described) to be midway between the leading and trailing edges.

Abstract: 1286236 Photo-electric attitude measuring ROBERT BOSCH GmbH 18 June 1970 [18 June 1969] 29521/70 Heading H4D [Also in Division G1] To measure vehicle wheel axle angles, mirrors 12 are mounted on the wheels 10 with their planes normal to the respective axles, projectors 13, which in a datum position are aligned with each other, project measurement diagrams 21 via respective mirrors 12 on to fixed screens 18 adjacent the associated projectors, and the projectors are moved angularly to align their diagrams with datum lines on the screens 18 so that the angular deflection of each projector is a measure of the angle of the associated axle. The projector is movable about perpendicular axes 14, 15 and is rigidly coupled to a tapping point 16 of a variable resistor 17 in a bridge circuit (Fig. 5, not shown) or feeding an indicator 27 as shown, or other data-processing or signalling device. Camber angle is measured by adjusting the projector about the horizontal axis 14 and track angles by adjustment about the vertical axis 15. For automatic adjustment servomotors 28 acting about the two axes are controlled by photodiodes 19, 20 in the screen 18, the diagram 21 defining light-dark boundaries 22, 23 for co-operation with the photodiodes 19, 20 respectively. Alternatively a single servomotor may be used to move the projector 13 about an oblique axis so that the diagram moves diagonally across the screen. To increase the range of the device, the boundaries 22, 23 may be defined by different coloured bands of light, each colour illuminating half the diagram, said halves being at right angles to divide the diagram into quarters (Fig. 3, not shown). The photodiodes then have suitable colour filters. In a modification, the projectors are fixed, and the wheel mirrors 12 or additional intermediate mirrors are angularly adjusted and their deflections sensed.
