Title: Colour motion picture film playback system
IPC: H04N9/79
Filed: 1972-03-17
Abstract: 1419771 Image pick-up tubes RCA CORPORATION 6 March 1973 [17 March 1972] 12696/72 Heading H1D [Also in Divisions H3-H5] In apparatus for providing luminance and chrominance colour television signals, e.g. N.T.S.C. from a colour cine film 12, Fig. 1, the image of two successive frames 14 and 15 are projected on to respective targets of a television camera tube 18, the targets being formed from half discs and being scanned by respective beams from electron guns 21, 22 the scanning rasters being exactly the same due to a common deflection system 23, the first frame 15 being projected on to the upper target 19 via a colour encoding striped filter 26 to provide the chrominance signal at output 24 and the second frame 14 being projected on to the lower target 20 to provide the luminance signal at output 25. The luminance signal, having a bandwidth extending up to 3À5 MHz Fig. 2b, is extracted by low pass filter 40, Fig. 3 and fed to adder 39. The spatial filter 26 produces two chrominance signals 28 (e.g. red and blue) quadrature modulated on a 2 MHz carrier, Fig. 2a and a narrow band reference signal 27 at 1 MHz. These two signals are processed together to cancel out any errors due to scanning or filter inaccuracies. The chrominance signals and the reference signal are respectively extracted by band-pass filters 32 and 36. The chrominance signal has its carrier shifted to 5À58 MHz by mixing at 33 with the output of oscillator 34 and then to 3À58 MHz by mixing at 35 with the frequency doubled reference signal from multiplier 37. The chrominance signal now on the standard carrier of 3À58 MHz is combined with the luminance signal at adder 39 for modulation on the V.H.F. carrier at 41.  Instead of being on the target face of tube 18, the spatial filter may be provided adjacent the films, Fig. 4 (not shown) or in the centre of a lens projection system, Fig. 5 (not shown) such that the film's image is focussed on the filter and the image of film and filter is in turn focussed on the targets.

Abstract: 1,091,852. Fluid-pressure servomotor systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 20, 1966 [March 26, 1965], No.12875/65. Heading G3P. [Also in Division F1]  Control apparatus for a variable air intake of a gas turbine engine comprises a body 10 located downstream of the intake and provided with a passage 11 restricted at 13. A temperature sensitive element 14 downstream of the restriction controls a by-pass valve 19 in passage 17 via an electric motor 20. The pressure drop across the restriction is communicated via lines 15, 16 to capsules 25, 26 connected to opposite ends of an evacuated capsule 27. Capsule 26 contacts a pivoted jet tube 29 controlling a servopiston 32 connected to the variable intake. Capsule 25 contacts the free end of a lever 28. A shaft 33 extending from the servopiston carries a cage 34 in which are located rollers 35 which contact the jet tube and lever 28. In use, the element 14 adjusts valve 19 to determine the effect of the flow through ejector 18 upon the pressure downstream of the restriction. The piston 32 varies the air intake, preferably by actuating a relay valve controlling the jacks of the intake vanes. The temperature-responsive modification of the differential pressure signal 15, 16 ensures that the mass flow-rate to the engine is substantially constant.
