Title: Television camera arrangements
IPC: H04N5/228
Filed: 1972-05-12
Abstract: 1426433 Cathode-ray tube circuits EMI Ltd 10 May 1973 [12 May 1972] 22279/72 Heading H4T The adverse effects of residual charges on the target of a pick-up tube that has been exposed to scenes which include areas of intense illumination and which give rise to charges which are too large to be reduced to cathode potential by a single scan are removed by scanning, assuming a conventional interlaced raster, alternate lines of the first field twice in successive line scanning periods (the intervening lines of this field being left unscanned) the potential of the beam during the first scan being such that charges on the target are reduced to a predetermined maximum level (e.g. equivalent to peak white) and during the second scan the beam potential being at a lower level (e.g. zero), the video signals generated during the first scan being suppressed whilst thsoe generated during the second scan are repeated by means of a delay line in order to provide a continuous video output. The scanning line sequence is thus 1, 1; 5, 5; 9, 9 &c. during the first field and during the second field, instead of employing the sequence 2; 2; 6, 6; 10, 10 &c. symmetry of the two interlaced fields is effected by employing the sequence 3, 3; 7, 7; 11, 11 &c. To effect the required scans a half line frequency square wave and a half field frequency square wave, each of appropriate amplitude, are combined with the normal field scanning waveform. It is stated that the invention may be used in conjunction with the invention described in Specification 1,426,434 which employs a similar scanning sequence but without variation of beam potential to reduce target lag. This use results in scan sequences of 1, 1, 1; 7, 7, 7; 13, 13, 13, and 4, 4, 4; 10, 10, 10; 16, 16, 16; &c. with appropriate beam potential, the video signals generated during the second scan of each line being repeated twice at intervals of one scanning line. The invention is especially applicable to the chrominance tube (or tubes) of colour television cameras which have a separate luminance tube since the loss of vertical resolution is of little significance.

[Class 80 (i).] Relates to rope or cable gearing of the kind described in the parent Specification in which the rope &c. is wound more than once around a driving-drum, axial movement of the points at which the rope reaches and leaves the drum being prevented by carrying the rope upon a chain movable axially as the drum turns. In this Specification, two or more ropes &c. are wound upon one or more chains moved axially by a single traversing device. A single chain 11, Figs. 2 and 3, which may be toothed to engage grooves in the drum, is coiled upon the drum and has two longitudinal grooves in its outer surface receiving a rope 16 at each end of the drum. The lateral faces of the end coils of the chain engage, with some freedom, chains 18 the rollers 17 of which bear against inclined tracks on stationary traversing members 15. Blocks 19 and flanges 93 control lateral movement of the chains 18, and ledges 90 at the top and bottom of the members 15 maintain the chains concentric with the drum. In a modification, the concentricity of the chains 18 is ensured by the use of adjustable split tracks carried by the members 15. In the construction shown in Fig. 5, four ropes 16 are wound in pairs on two chains 11 arranged side by side on worms 58 which are rotated by links 75 connected to a wheel 75<1> loose on a fixed eccentric 77.
