Title: Demodulator cicuit for colour television signals
IPC: H04N11/16
Filed: 1975-06-30
Abstract: 1519822 Television receivers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA S.p.A. 30 June 1975 [5 July 1974 17 Jan 1975] 27500/75 Heading H4F An arrangement for demodulating a PAL chroma signal includes means for separating the two colour components which are then passed to respective synchronous demodulators. The demodulators are also fed with respective sub-carriers generated by means controlled by a half line frequency switching means so arranged that the sub-carriers have the required phase irrespective of the phase of the switching means and without the need for phase identification. means. In one embodiment, Fig. 1, the chroma signal is fed direct and via an n-line delay 2 (n odd) to an adder 4 and subtractor 5 which respectively provide the B-Y and R-Y components, the R-Y component inverting at half line frequency. Demodulators 6, 7 generate the colour difference signals. The chroma signal also passes to a burst gate 10 which passes the bursts to switch 11 switched at half line frequency to deliver successive bursts to alternate oscillators 12, 13. The oscillators generate respective constant phase sub-carriers in phase with the bursts applied to them. The sub-carriers are applied to adder 14, which delivers a subcarrier phased along the B-Y axis to demodulator 6, and to subtractor 15, which delivers a sub-carrier phased along the R-Y axis. An inverter 16 inverts the R-Y sub-carrier during alternate lines. Because the inverter is controlled by the half line frequency signal that controls switch 11 the sub-carrier fed to demodulator 7 is inverted at half line frequency and has the phase required for the R-Y component to be demodulated. In a second embodiment, Fig. 2, the chroma signal is fed directly and via a delay 2 to a reversing switch 30 switched at half line frequency. The switch directs alternate line signals to one input of an adder 4 and a subtractor 5, and the remaining line signals to the other input. The adder provides the B-Y component to a demodulator 6 and the subtractor the R-Y component to a second demodulator 7. The R-Y component has constant phase. Constant phase demodulating sub-carriers are derived from generators 22, 23, phase-controlled by constant phase bursts separated by gates 20, 21.

Abstract: 1301155 Fluidic elements BORG-WARNER CORP 10 June 1970 [25 June 1969] 28236/70 Heading G4P [Also in Division F1] A monostable fluidic switch has a control nozzle 132 and one or more additional nozzles 138 opening in to interaction chamber 114. Bias air pressure, e.g. atmospheric, is applied at nozzle 137. A liquid jet formed by nozzle 134 normally attaches to one sidewall of exit duet 121. One or more of the nozzles 138 are connected to the control air pressure inlet 131 and to the downstream part of exit duct 121 by a channel 139, shown partly in broken line, which formed in the plate forming the lower wall of duct 121. The presence of this channel aids attachment and reattachment of the jet to the side-wall. For the duration of a pulse of air at inlet 131 the jet switches to exit duct 124. As applied to the control of the flow of fuel to an I.C. engine, fuel from sump 149 is supplied to nozzle 134 by pump 147. In the absence of a control pulse from unit 143 the fuel returns to the sump via exit duct 121. Unit 143 emits pulses of frequency related to the engine speed and of duration related to the load. During a pulse the fuel flows through exit duct 124 and via restrictor 127, the resulting jet passing through chamber 164 and restrictor 163 to port 129 in the engine's air intake system. Chamber 164 has vents 158, 159 and, together with restrictor 127, serves to isolate the interaction chamber 114 from the varying vacuum at port 129.
