Title: Telemeasuring Switch
IPC: H03K17/693
Filed: 1966-12-28
Abstract: 1,169,530. Transistor switching and pulsegenerating circuits. THOMSON-C.S.F. 28 Dec., 1966 [29 Dec., 1965], No. 58022/66. Heading H3T. A switch for sequentially switching a plurality of input channels E1, E2 ... E n  to a single output channel S comprises a plurality of field effect transistors T1, T2 ... T n  with their source-drain paths connected between a respective input and the output S, which transistors are rendered conductive sequentially by signals applied to their gate electrodes from respective bi-stable circuits B1, B2 ... B n . Suppose transistor T1 is initially conductive. A subsequent positive clock pulse H1 will trigger bi-stable circuit B1 so that transistor T1 is rendered non-conductive, and simultaneously a negative pulse is produced at the output of capacitor C1 to trigger circuit B2 such that transistor T2 is switched on. A subsequent positive clock pulse H2 (pulses H2 being intermediate pulses H1) triggers circuit B2, cutting off transistor T2 and triggering circuit B3 to switch transistor T3 on. In this manner the transistors are switched on in sequence. A free-running multivibrator M (Fig. 4, not shown) is synchronized by the output of bistable circuit B n  and resets bi-stable circuit B1 so as to initiate a further sequence.

Abstract: 1416140 Television EMI Ltd 28 Nov 1972 [30 Dec 1971] 60813/71 Heading H4F A video signal A at input 11, e.g. a colour signal, is non-additively mixed with a video signal B or caption signal at input 18, the composite output signal from mixer 17 comprising at any instant the larger of the two input signals, and the arrangement including a selectively operable switch 20 which when a caption signal is being mixed with signal A causes the caption signal's amplitude to be increased, e.g. doubled by multiplier 21, so that it is greater than the maximum level of signal A. This prevents the mixed signal containing chroma information instead of the required peak white caption signal. In addition the caption signal is preferably clamped 22 below the minimum level of the signal A during blanking intervals so that the negative portions of the burst signals in signal A are not removed by the caption signal, i.e. the complete burst signal from signal A is present in the mixed signal. With ganged switches positioned as shown, i.e. for a caption signal input, the inversely related (inverter 26) clamping levels of circuits 13 and 22 are determined by potential divider 25, but when the video signal A is mixed with the video signal B the switches 20 and 24 are caused to assume their V positions and the relative clamping levels of the two signals are controlled by fader 15.
