Patent GB-1257582-A (GB)
IPC: H04N9/24
Filed: 1970-05-06
Abstract: 1,257,582. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 May, 1970 [9 May, 1969], No. 21877/70. Heading H4F. In colour television display apparatus of the type having a beam indexing tube 1 which provides an index signal 19 of ambiguous phase, e.g. of frequency <SP>3</SP>/ 2 f, if f is the writing frequency, and an unambiguous signal 113 of frequency f which in response to the output 125 of a gate pulse generator 77 is fed to a frequency divider 27 to set it in a predetermined condition until index signals are received thereby, if the output 125 of generator 77 is not synchronous with the signals 19 and 113, it is not clear when the signals 19 will begin to control the divider 27 and there will be a corresponding phase uncertainty in the outputs of the divider. Thus in Fig. 3, the signal 125, (167) ends at t 7 , half a pulse before t 8 , the true commencement of signal 19. In the present arrangement, the signal 113, (165 in Fig. 3) is fed directly, and via an invertor 131 and AND gate 121 to the reset and set inputs, 111 and 117  respectively, of a bi-stable 109, so that the signal 107, (171) fed to divider 27 ends at t8, i.e. it terminates at a time determined by the signal 113 acting in conjunction with the pulse 125. If the pulse 125, (167) ended between t 5  and t 6  the signal 107 would terminate at t 5 , one writing cycle before t 8 . It is thus possible to use digital frequency divider 27 in the circuit. As described, this is provided with balanced index signal inputs 233, 235 and the signal 171, (107) from the trigger 109 and, after the cessation of signal 171, gives three pairs of balanced outputs 221, 223, 225, 227, 229, 231 of frequency f/ 2  and relatively displaced by 120‹, which are modulated by colour signals 55, 57, 59 at 53. Since the outputs of the divider have a unity mark to space ratio, unwanted harmonics in the modulator output are easily removed by a filter 65, and a gate 71 which is controlled by the circuit 77 so as to be shut when the run-in signal is preset and open when the index signal is preset, passes the signals to a circuit 23 where they are mixed with the index signal to give an output 83 of writing frequency f. At 87 the signal 83 is combined with a corrected luminance signal M passed by a gate 93 during both the run-in and index signals, and passed to a grid 104 of the indexing tube. During the run-in signal a D.C. level is introduced into the M signal such that a favourable run-in signal to noise ratio is obtained. The circuit 77 controlling gates 121, 71 and 93 receives run-in signals 113, and field and line sync. pulses 137 and 139 respectively, in order to provide the correct outputs. Detailed circuitry for the gate 121, trigger 109, divider 27 and modulator 53, in a form suitable for integrated circuit techniques, is given, Figs. 2, 4 and 5 (not shown).

Abstract: 1288609 Electric selective signalling SPERRY RAND CORP 29 Dec 1969 [14 Jan 1969] 63039/69 Heading G4H Apparatus for producing an analogue output signal V 0  proportional to the angular difference between an electrical analogue input signal representing a first angle # and an electrical digital input signal representing a second angle # comprises a controller 30 for receiving the digital input signal and sine and cosine functions of the analogue input signal, a digital to analogue converter 36-39, 41-44 for converting the digital signal to first and second pairs of sine and cosine functions of a first value #a and a second value #b of the digital signal (where #a<#<#b) and transformers 51, 56 for providing a first difference signal which is a function of (#a-#) and a second difference signal which is a function of (#b-#). As described the apparatus is used with a flux valve 11 from which the analogue input signal is derived to determine direction with respect to the horizontal component of the earth's magnetic field, # being the angle between this component and the axis of the valve. The flux valve consists of a primary coil 12 energized by a source of frequency # and secondary coils 14-16 which are connected to the primaries 23, 24 of a transformer 25. The two outputs of the transformer are fed to the controller shown in Fig. 2 which comprises the four transformers 36-39. The controller 30 generates the signal V 0 , the polarity of which is determined by a phase detector 32 fed with a reference signal. The output of the phase detector is fed to an up/down counter 33 in which logic circuits are gated by pulses from a master clock, the count stopping when the digital signal # equals # since V 0  then equals zero. The digital signal # may be processed in a digital computer or displayed to a pilot to control the heading of a craft in which the apparatus is installed. The two most significant bits of # determine the quadrant in which # lies whilst the next three significant bits select the taps of the transformers 36-39 to determine # within a range of eleven degrees and generate a coarse signal V sin (#a-#) sin wt. The coarse signal is combined with a fine signal derived from a resistive ladder digital to analogue converter 45 controlled by the ten least significant bits of # to provide an accurate digital representation of #.
