Title: Automatic luminance channel frequency response control apparatus
IPC: H04N9/77
Filed: 1975-10-16
Abstract: 1525406 Television RCA CORPORATION 16 Oct 1975 [21 Oct 1974] 42521/75 Heading H4F A signal processing unit 36, Fig. 1, operates as a variable bandwidth luminance filter controlled in response to the amplitude of a chrominance signal. Signal processing unit 36 is included in luminance channel 16 and serves to attenuate undesirable signals present in luminance channel 16 such as chrominance or sound signals or both, while relatively accentuating or peaking the amplitudes of high frequency components of the luminance signals to improve the transient response and fine detail resolution of the television receiver. Signal processing unit 36 includes provisions for automatically controlling the bandwidth of luminance channel 16 in response to control signals generated in chrominance channel 14. Signal processing unit 36 may also have provisions for controlling the amplitude of a peaked portion of the luminance channel frequency response in response to manual control signals or control signals generated in chrominance channel 14. Furthermore, signal processing unit 36 may also serve to equalize the time delays of the signals processed in chrominance channel 14 and luminance channel 16. Processing unit 36 includes a tapped delay line 116 from which a plurality of signals a, b, m, c, d delayed by different amounts are applied to respective weighting amplifiers 114 prior to combinations, as shown in Fig. 1, to produce the filtered output luminance signal Vo. Mixer 122, described more fully w.r.t. Fig. 2 (not shown), provides a composite output comprised of controlled amplitude portions of the inputs V bw1  and V bw2 . These controlled portions are in inverse relation to each other and one is derived in direct proportion to the amplitude of the chrominance signal supplied from the chrominance channel over line 32. Control of the amplitude of the peaked portion of the luminance is achieved manually or in response to the chrominance amplitude. Instead of producing controlled amplitude portions of inputs V bw1  and V bw2 , mixer 122 may switch discreetly between these signals, passing either as output, in response to a signal such as that derived from a "colour killer" unit 28. In order to change the frequency of the peaking signal additional delayed signals may be tapped from the delay line 116 and combined with signals a and d to feed the peaking control 124. This arrangement is described w.r.t. Fig. 5 (not shown). Figs. 3, 4 and 6 (not shown) are amplitude VS frequency transfer characteristic graphs indicating the bandwidth variation and peaking frequency variation with attenuation of control signals applied respectively to mixer 122, Fig. 1, and a similar mixer (520) Fig. 5 (not shown) additionally employed in the latter embodiment.

In a fluid-pressure servomotor system an error signal P sensed by an orifice plate 19 is fed to a device 13 where it is compared with a signal REF derived from a controller 14 to produce a digital output which is totalized and converted into an analogue signal which in turn is fed to a diaphragm valve 11, 12 in the output line 10 feeding the process being controlled, e.g. controlling the thickness of sheet steel or other material in a rolling or extrusion process. Device 13 has a comparator 20 which produces "Up" or "Down" signals according to whether P exceeds REF and feeds them to binary counter stages B o  -B 4  which are also fed with clock pulses generated in an oscillator 23. The outputs of stages B 0 -B 4  are fed to a summating device 24 through resistors R 0  -R 4  of values inversely proportional to the binary values of the associated stages. Device 24 generates an analogue signal proportional to the summated digital signal and feeds it to valve 11, 12. If it is desired the comparator 20 and oscillator 23 can be replaced by an electronic digital device 15 which feeds the required signals to device 13 through a fluid transducer 16. Fig. 5 (not shown) illustrates a modified arrangement feeding a push-pull signal to device 24.

Abstract: 1,199,859. Loud-speakers. UNITED AIRCRAFT CORP. 9 Sept., 1968 [16 Oct., 1967; 28 Feb., 1968], No. 42739/68. Heading H4J. [Also in Divisions F1, F3 and G1] Acoustic waves are generated in an ionized gas stream by modulating the D.C. current flowing between electrodes disposed in the stream. Electrodes 15, 16 project into flame 17 and are connected to D.C. bias supply 14 and auxiliary supply 13 so that a direct current flows between the electrodes. A signal source 11, e.g. oscillator, tape recorder or the like, is connected . to amplifier 12 whose output is applied through capacitor 18 to the electrode circuit at 20, 21 to modulate the D.C. current. The circuit parameters are chosen so that the direction of current flow in the D.C. circuit is not reversed and the voltage of auxiliary source 13 is chosen to keep the voltage above the level where distortion becomes significant. The system provides an omnidirectional loudspeaker or an ultrasonic generator. The system may be used for generating acoustic waves in a combustion chamber, such as a rocket motor, and by varying the modulation frequency any resonances can be recorded on a pressure transducer so that the necessary corrective action can be taken. The system could also be used to modulate the thrust of a rocket motor employing a pressure-sensitive propellant. The system can also be used to suppress the noise in an ionized gas stream by detecting the vibration noise of the stream, preferably by photo-electric means (see Division G1), and phase shifting the oscillation before feeding it to the electrodes so that the vibrations in the stream are nulled.
