Title: Digital pcm coded colour television system
IPC: H04N19/94
Filed: 1971-08-31
Abstract: 1345922 Colour television OFFICE DE RADIODIFFUSION-TELEVISION FRANCAISE 31 Aug 1971 [31 Aug 1970] 40659/71 Heading H4F  An arrangement for transmission of digital data representing colour television information employs for each scan line a set of up to (say) 16 digitized colour signals which are accumulated in a store at the transmitter during the scan, the addresses (four-bit) in store being transmitted in lieu of the colour values, and the colour values being transmitted in address order during the line-blanking periods and stored at the receiver. The invention makes use of the fact that the number of different colour signals normally found in any single line is limited, to reduce the number of bits needed to digitally encode the colour signals. As described in connection with a PAL system (or S.E.C.A.M. system) two colour signals  are formed and sampled at intervals for an A-D converter providing a six-bit signal for each I and Q signals may be used for an N.T.S.C. system. Each such 12-bit colour signal is compared with all the colour-signals previously entered into a store, and is itself entered in store only if it is new; in any case the address of this new colour signal is transmitted as a 4-bit address (in order to ensure that sixteen colour signals will be adequate, the difference between any two may be required to exceed a predetermined threshold before a new signal value is recognized). With each transmitted colour signal address is associated a 4-bit coding of the luminance; thus eight bits in all are transmitted for each such coding, and this system operates for each 400n Sec. period (a four-element picture period) during which a rapid change in luminance is not detected. A delay-line is used to detect the luminance change and if this exceeds a predetermined threshold it is coded into one of three two-bit signals representing the sign and magnitude of the change, and the transmission of the coded colour signals is inhibited while the luminance increment signals are transmitted. The binary signals are transmitted in a so-called "pseudo-ternary" form in which binary zero is represented by no-pulse and binary one by either a positive or a negative pulse, the switching between the two modes (i.e. "rapid luminance change" and "no rapid luminance change") being indicated by successive ones being of the same, instead of the otherwise different polarity.

Filed: 1974-09-23
Abstract: 1474454 Monitoring dimensions photoelectrically GALLAHER Ltd 15 Sept 1975 [23 Sept 1974] 41326/74 Heading G1A Cigarette testing apparatus comprises: means for continuously advancing cigarettes in succession transversley to their length; an optical device in which at least two light beams are transmitted towards respective photo-detectors across the plane of travel of the cigarettes and at different angles to their direction of travel; and means responsive to the photo-detectors to signal when the time of interruption of the beams by a cigarette is outside a predetermined range. Assemblies 12 comprising pairs of filter-tipped cigarettes 25 Fig. 3 joined at their filter ends, at which ends they are covered with imitation cork wrappings 26, are conveyed in cradles 13 of a belt (14) Fig. 1 (not shown) through a device Fig. 2 for detecting an abnormal outline size due to a wrinkle or unstuck end in a wrapping. An upper block 19 contains three focused LEDs T1-T3 directing beams at, respectively, 145 degrees, 90 degrees and 35 degrees to the direction of travel, towards respective focused phototransistors P1-P3 mounted in a lower block 20. Any irregularity of outline in a wrapping will cause at least one beam to be interrupted for an abnormal time, while an oval cigarette will merely cause interruptions which vary in a complementary way. Phototransitor signals are amplified at 30 Fig. 4, pulse-shaped at 31 and applied to a summing integrator 33 which, at the end of a measurement cycle, produces a voltage dependent upon the summed times of interruption of the three beams. A voltage outside upper and lower limits set by comparators 34 is gated to a memory 37 which activates a rejection device (23) Fig. 1 (not shown) when the faulty cigarette passes it. In an alternative embodiment Figs. 5, 6 (not shown), further sources (T4, T5) shine in directions parallel to the cigarette axes along lines above and below the plane of travel and spaced only a little wider than the maximum permissible cigarette diameter. If either of two detectors (P4, P5) senses any interruption of a respective beam, a fault is signalled by a respective bi-stable, 46 Fig. 4.
